Panama Canal expansion project

Components of the project

The Panama Canal expansion project, also called the Third Set of Locks Project, is intended to double the capacity of the Panama Canal by 2016 by creating a new lane of traffic and allowing more and larger ships, the New Panamax size, which are about one and a half times the current maximum width and length (known as Panamax) and can carry over twice as much cargo.

The project is planned to:

  • Build two new locks, one each on the Atlantic and Pacific sides, and excavate new channels to the new locks. Each will have three chambers with water-saving basins..
  • Widen and deepen existing channels.
  • Raise the maximum operating level of Gatun Lake.[1]

Then-Panamanian President Martín Torrijos formally proposed the project on 24 April 2006, saying it would transform Panama into a First World country. A national referendum approved the proposal by a 76.8 percent majority on 22 October, and the Cabinet and National Assembly followed suit. The project formally began in 2007.[2] It was initially announced that the Canal expansion would be completed by August 2014 to coincide with the 100th anniversary of the opening of the Panama Canal but various setbacks, including strikes and disputes with the construction consortium over cost overruns, pushed the completion date first to June 2015 then December 2015. [3] [4] On 14 April 2015, Canal Project Minister Roberto Roy announced that the Canal expansion would be operational by 1 April 2016.[5]

The project is expected to create demand for ports to handle New Panamax ships. Several U.S. Eastern Seaboard ports will be ready for these larger ships, and others are considering renovations, including dredging, blasting, and bridge raising.[6] In the UK, the Port of Southampton can handle post-Panamax vessels and is expanding to accommodate more,[7] while the Port of Liverpool will be capable by 2015 and others are considering such expansion.[8]

The Panama Canal has been working at full capacity for several years. Several dozen vessels queuing at the Pacific Ocean waiting to enter the canal in 2013.

The Panama Canal has a limited capacity determined by operational times and cycles of the existing locks and further constrained by the current trend towards larger (close to Panamax-sized) vessels transiting the canal, requiring more transit time in the locks and channels. Also, periodic maintenance on the aging canal requires shutdowns of this waterway. Demand is growing due to the growth of international trade, and many users require a guaranteed level of service. Despite the gains which have been made in efficiency, the Panama Canal Authority (ACP) estimated that the canal would reach its maximum sustainable capacity between 2009 and 2012.[1] The long-term solution for the congestion is the expansion of the canal with a third set of locks.

Vessels waiting at Gatun Lake to cross the Gatun Locks to exit the canal at the Atlantic side in 2014. At the left of the existing locks is the construction area for the new set of locks with water saving chambers part of the Panama Canal expansion project.

The size of ships that can transit the canal, called Panamax, is constrained by the size of the locks, which are 110 ft (33.53 m) wide and 1,050 ft (320.04 m) long, and 41.2 ft (12.56 m) deep. The third set of locks will allow transit of larger, Post-Panamax ships, which have a greater cargo capacity than the current locks can handle.

All of the canal-widening studies since the 1930s have determined that the best way to increase canal capacity is by building a third set of locks larger than the 1914 locks. The US began excavations for new locks in 1939, but abandoned them in 1942 because of the outbreak of World War II.[1] This conclusion was again reached in the 1980s by the tripartite commission formed by Panama, Japan, and the US. More recently, the studies developed by the Panama Canal Authority (Spanish: Autoridad del Canal de Panamá (ACP)) for its 2025 master plan confirm that a third, larger set of locks is the most suitable, profitable, and environmentally responsible option.[1]

Former president Martín Torrijos, in an 24 April 2006 speech announcing the project, said that the canal "is like our 'petroleum'. Just like the petroleum that has not been extracted is worthless and that in order to extract it you have to invest in infrastructure, the canal requires to expand its capacity to absorb the growing demand of cargo and generate more wealth for Panamanians".[9]

While the canal expansion is being completed, and considering the high operational costs of the vessels, the long queues that occur during the high season December through to March (sometimes up to a seven-day delay), and the high value of some of the cargo transported through the canal, the ACP has implemented a Transit Booking System and Transit Slot Auction to allow a better management of the scarce capacity available and to increase the level of service offered to the shipping companies. The scheme gives users two choices: (1) transit by order of arrival on a first-come, first-served basis, as the canal historically has operated; or (2) booked service for a fee—a congestion charge. The booked service allows two options of fees. The Transit Booking System, available online, allowing customers who do not want to wait in queue to pay an additional 15% over the regular tolls, guaranteeing a specific day for transit and crossing the canal in 18 hours or less. ACP sells 24 of these daily slots up to 365 days in advance. The second choice is high priority transit. Since 2006, ACP has made available a 25th slot, sold through the Transit Slot Auction to the highest bidder.[10] The main customers of the Transit Booking System are cruise ships, container ships, vehicle carriers, and non-containerized cargo vessels.[11]

Cargo volume

The Panama Canal Authority predicts that the volume of cargo transiting the canal will grow by an average of 3% per year, doubling the 2005 tonnage by 2025. Allowing larger vessels to transit the canal will move more cargo per transit and volume of water used.

Historically, the dry and liquid bulk segments have generated most of the canal's revenues. Bulk cargo includes dry goods, such as grains (corn, soy, and wheat, among others), minerals, fertilizers, coal, and liquid goods, such as chemical products, propane gas, crude oil, and oil derivatives. Recently, containerized cargo has replaced dry bulk as the canal's main income generator, moving it to second place. Vehicle carriers have become the third-largest income generator, replacing the liquid bulk segment. Shipping industry analyses conducted by the ACP and top industry experts indicate that the canal expansion will be beneficial to both the canal and its users because of the demand that will be served by allowing the transit of more tonnage.[1]

However, the question is whether the trend on which the ACP makes those projections can continue for a generation.

The growth in usage of the Panama Canal over the past few years has been almost entirely driven by increased US imports from China passing through the canal en route to ports on the US East and Gulf coasts. But it is increasingly recognized in both the US and China that this imbalance in trade is unsustainable and will be reduced via some sort of adjustment in the coming years[12] (although such an imbalance need not be made up by physically shipped goods, but could be made by other trade such as intellectual property as China upgrades its intellectual property protection laws). The ACP, however, presumes that trade will continue to grow for a generation as it has for the past several years.

One of the central points made by critics of canal expansion, most prominently former canal administrator Fernando Manfredo, is that it is unrealistic to attempt to predict canal usage trends over a generation, improbable to expect that US imports from China will continue to grow for a generation as they have the past few years, and irresponsible to bet Panama's financial future on such a projection.


The most direct competition to the canal comes from alternative routes that present options for transporting cargo between the same points of origin and destination.

The opening of the Russian Northern Sea Route and the Canadian Northwest Passage to commercial traffic could pose an alternative to the canal in the long term. Warmer waters in the Arctic Ocean could open the passage for an increasing number of months each year, making it more attractive as a major shipping route. However, the passage through the Arctic would require significant investment in escort vessels and staging ports. The Canadian commercial marine transport industry does not anticipate that this route will be a viable alternative to the Panama Canal within the next 10 to 20 years.[13]

The two main current competitors of the Panama Canal are the US intermodal system and the Suez Canal. The main ports and merchandise distribution centers in these routes are investing in capacity, location, and maritime and land infrastructure to serve post-Panamax container ships and their larger cargo volumes. According to the ACP, the growing usage of such ships in transcontinental routes competing with the canal is irreversible. If so, by 2011, approximately 37% of the capacity of the world's container ship fleet will consist of vessels that do not fit through the current canal, and a great part of this fleet could be used on routes that compete with Panama.[1]

The proposal states that strengthening the canal's competitive position will allow it to accommodate demand and serve its customers. If the canal had the capacity to serve the growing demand, Panama could become the most important connectivity hub on the continent by joining together north–south continental routes and east–west transcontinental routes. Accordingly, the canal will continue to be viable and competitive in all of its routes and segments, and contribute significantly to Panama's development and growth while maintaining its position as a major world trade route.[1]


Maximum sustainable capacity of the Canal with the new locks

According to the studies conducted by the ACP in 2005, the canal would reach its maximum sustainable capacity between 2009 and 2012. When it reaches this capacity it will not be able to continue to handle growth in demand, resulting in a reduction in the competitiveness of the Panama maritime route.

As approved by the Panamanian people, construction for the expansion project is slated to conclude by April 2016. The ACP will use all possible means to stretch capacity until the construction is completed.

The proposed expansion of the canal by the construction of a third set of locks will allow it to capture the entire demand projected through 2025 and beyond. Together, the existing and new locks will approximately double the capacity of the present canal.[1]

Critics such as former legislator Keith Holder, co-author of the legislation that created the ACP, point out that canal usage is seasonal and that even during the few months when it is most crowded, the bottleneck that slows traffic is not the locks but the narrow Culebra Cut, which has a limited capacity for large ships to pass one another.[14]

Although the canal is nearing its maximum capacity, this does not mean that ships will be unable to transit it. Rather, the canal's growth capacity will stagnate and that it will not capture additional cargo volumes.[1]

The former head of the Panama Canal's dredging division, Thomas Drohan, a critic of the expansion plan, discounts allegations that this is a problem in the short term. He argues that if the supply of any good or service becomes short, businesses can raise their prices; this would apply to Panama Canal tolls as much as it does to petroleum.[15]

The canal today has two lanes, each with its own set of locks. The expansion project will add a third lane through the construction of lock complexes at each end of the canal. One lock complex will be located on the Pacific side, southwest of the existing Miraflores Locks. The other will be located east of the existing Gatun Locks. Each of these new lock complexes will have three consecutive chambers designed to move vessels from sea level to the level of Gatun Lake and back down again.[1]

Each chamber will have three lateral water-saving basins, for a total of nine basins per lock and 18 basins in total. Just like the existing locks, the new locks and their basins will be filled and emptied by gravity, without the use of pumps. The location of the new locks uses a significant portion of the area excavated by the United States in 1939 and suspended in 1942 because of World War II. The new locks will be connected to the existing channel system through new navigational channels.[1] The new lock chambers will be 427 m (1,400.92 ft) long, 55 m (180.45 ft) wide, and 18.3 m (60.04 ft) deep. They will use rolling gates instead of miter gates, which are used by the existing locks. Rolling gates are used in almost all existing locks with dimensions similar to those being proposed, and are a proven technology. The new locks will use tugboats to position the vessels instead of electric locomotives. As with rolling gates, tugs are successfully and widely used for these purposes in locks of similar dimensions.[1]

Water-saving basins

The new locks have water-saving basins to reduce the volume of water that is needed in lock operation. The operation of both the old and new locks uses gravity and valves. There is no pumping involved.

Operation of the locks, old and new, will use water from Gatun Lake. Even in the current situation with two lock lanes, water supply can be limited at the end of Panama's dry season, when the lake's water level is low. The addition of a third set of locks means that this water supply issue must be addressed.

Three basins are associated with each lock chamber. The volume lost per cycle is two-fifths of the "moving water" chamber volume. The other three-fifths is reused. Interestingly, an equal savings of water, based on the same principle, could be reached by adding more lock chambers. Constructing a stair of eight chambers (instead of three) to elevate 85 ft (26 m) would use an 11 ft (3.25 m) water slice per cycle. However, this would require ships to travel through eight locks, making ship handling less efficient.

Water usage is calculated per single lock cycle. It is determined by the water volume in a lock chamber between the levels it handles. Essentially, each cycle uses the volume of water discharged by the lock chamber (its width multiplied by its height and depth). When the locks are in stairs, as in the Panama Canal, only the first (highest) lock chamber matters for this calculation. None of the lower locks use additional water; they have the same volume. Moreover, the ship's underwater volume does not matter, because that volume is present both before and after the change in water level and thus is part of the non-moved volume.

Diagram of water-saving basins (ascending)

The water used per lock operating cycle is therefore equal to the amount of water that flows into the first (upper) lock chamber when filling it from Gatun Lake. Reducing this volume requires reducing the chamber's width, length, or elevating height. Note that the elevating height has already been reduced by staging the total 85 ft (26 m) elevation change into three locks. Were this change done in a single lock chamber, the water volume lost would be three times as much.

The water-saving basins function as follows: The volume of water moved by the lock chamber (e.g., a height of 30 ft (9 m)) can be divided into five equal horizontal "slices" (here, 1.8 m each). When the canal begins operation, the chamber is filled once from Gatun Lake. Then, when emptying the chamber, the top three slices (1, 2, and 3) are emptied, one by one, into to three basins, each at a successively lower elevation. That is, water slice 1 is emptied, using gravity and valves, into a basin that is at the same level as water slice 2. Then water slice 2 is emptied into a basin at the same level as water slice 3, and slice 3 is emptied into a basin at the same level as slice 4. Water slices 4 and 5 are emptied into the next lock chamber and "lost" (as in the original canal locks).

When the lock moves a ship upward, the chamber is closed, and the water from the basin at level 4 is let into the chamber, filling slice 5. Then basin level 3 fills level 4, and basin 2 fills level 3. Next, from levels 2 and 1 are filled from Gatun Lake, "costing" a volume of 12 ft (3.6 m) instead of 30 ft (9 m) over the chamber area (2/5 of the elevation height). The ship is now at the level of Gatun Lake and can cross it.

Navigational channels

According to the plan, a 3.2 km (2.0 mi)-long access channel will be excavated to connect the new Atlantic locks with the existing sea entrance of the canal. To connect the new Pacific-side locks with the existing channels, two new access channels will be built:

  • The 6.2 km (3.9 mi) north access channel, which will connect the new Pacific-side lock with the Culebra Cut, circumventing Miraflores Lake. This channel will run along the new Borinquen Dam that separates it from Miraflores Lake (which has a water level that is 9 m lower, due to the dislocation of the Pedro Miguel locks).
  • The 1.8 km (1.1 mi) south access channel, which will connect the new lock with the existing sea entrance on the Pacific Ocean (fig. 5).

The new channels on both the Atlantic and the Pacific sides will be at least 218 meters (715 feet) wide, permitting Post-Panamax vessels to navigate in a single direction.[1]

Maximum operating level of Gatun Lake

Canal elevations are referred to using the Precise Level Datum (PLD), which is close to the mean sea level of the Atlantic and Pacific entrances. The maximum operational level of Gatun Lake will be raised by approximately 0.45 meters (1.5 feet) from the present PLD level of 26.7 meters (88 feet) to a PLD level of 27.1 meters (89 feet). Combined with the widening and deepening of the navigational channels, this will increase Gatun Lake's usable water reserve capacity and allow the canal's water system to supply a daily average of 165,000,000 US gal (625,000,000 L; 137,000,000 imp gal) of additional water. This additional water volume is enough to provide an annual average of approximately 1,100 additional lockages without affecting the water supply for human use, which is also provided from Gatun and Alhajuela Lakes.[1]

Construction timeline

The construction of the third set of locks project was originally slated to take seven or eight years, with the new locks beginning operations between fiscal years 2014 and 2015, roughly 100 years after the canal first opened.[1][16] In July 2012, however, it was announced that the expansion project had fallen six months behind schedule, pushing the opening date back from October 2014 to April 2015.[17] By September 2014, the new gates were projected to be open for transit at the "beginning of 2016."[18][19][20][21]

In October 2011, the Panama Canal Authority announced the completion of the third phase of excavation for the Pacific access channel.[22][23]

In June 2012, a 100-foot-tall reinforced concrete monolith was completed, the first of 46 such monoliths that line the new Pacific-side lock walls.[24]

Sixteen new lock gates had to be installed as part of the canal expansion: eight on the Atlantic side, and eight on the Pacific. The installation process began in December 2014, with a 3,285-ton gate's installation on the Atlantic side; it concluded in April 2015, with the installation of a 4,232-ton gate on the Pacific side.[25][26]

In June 2015, flooding of the new locks began: first on the Atlantic side, then on the Pacific; by then, the canal's re-inauguration was slated for April 2016.[27][28][29][30]

In August 2015, a crack was reported in a concrete sill at the new Cocoli locks, but it was not anticipated to affect the project completion timeline.[31][32]


The main purpose of the canal expansion program is to increase Panama's ability to benefit from the growing traffic demand. This growing demand is manifested in both the increased cargo volumes and the size of vessels that will use the Panama route. In this sense, with a third set of locks, the canal will be able to manage the traffic demand forecast beyond 2025; total inflation-adjusted revenues for that year are predicted to amount to over USD $6.2 billion.[1]

Estimated cost

Cost estimates of the project

In 2006, ACP estimated the cost of the third set of locks project at US$5.25 billion.[1] This figure includes design, administrative, construction, testing, environmental mitigation, and commissioning costs, as well as contingencies to cover risks and unforeseen events, such as accidents, design changes, price increases, and possible delays. The cost of interest paid on loans during construction is not included. The largest cost is that associated with constructing the two new lock complexes—one each on the Atlantic and Pacific sides—with estimated costs of US$1.11 billion and USD $1.03 billion each, plus a USD $590 million provision for possible contingencies during their construction.[1]

Opponents contend the project is based on uncertain projections about maritime trade and the world economy. Roberto N. Méndez, an economist at the University of Panama, alleges that the economic and financial projections are based on manipulated data.[33] Independent engineers, most notably Humberto Reynolds[34] and Tomás Drohan Ruiz,[35] the former head of engineering and dredging of the Panama Canal, say that the project will cost much more than currently budgeted and that it is too risky for Panama. M. A. Bernal, a professor at the University of Panama, argues that confidence in the ACP's budget is undermined because of the involvement of engineering and consultancy firm Parsons Brinckerhoff. Parsons Brinckerhoff is best known for the Big Dig in Boston, which ended up costing three times the estimated amount, with several structural and safety concerns.[36]

Estimated profitability and financing

According to the ACP, the third set of locks will be financially profitable, producing a 12 percent internal rate of return. The project's financing is separate from the governmental budget. The state, which has a lower credit rating than the ACP, does not guarantee or endorse any loans borrowed by the ACP for the project. Assuming that tolls increase at an annual average rate of 3.5 percent for 20 years, and according to the traffic demand forecast and construction schedule deemed most likely by the ACP, the external financing required will be temporary and in the order of USD $2.3 billion to cover peak construction activities between 2009 and 2011.[1]

The ACP's revenue projections are based on questionable assumptions about increased canal usage and shippers' willingness to pay higher tolls instead of seeking competing routes. In a bid to attract new business as well as keeping the current customers, the ACP is looking to implement financial incentives in their toll programme, including a loyalty scheme, which are expected to combat the problems raised by increased fees.[37] With the cash flow generated by the expanded canal, investment costs are expected to be recovered in less than 10 years, and financing could be repaid in approximately eight.[1]

The $2.3 billion financing package for the canal expansion, signed in December 2008 in the midst of the global financial crisis, includes loans from the following government-owned financial institutions:

The financing is not tied; that is, contracts can be awarded to firms from any country. The loans are for 20 years, including a 10-year grace period. Under a common terms agreement, all five financial institutions agreed to provide the same loan conditions to the ACP. Shortly before, credit rating agency Moody's gave the ACP an A1 investment grade rating. Mizuho Corporate Bank and the law firm Shearman & Sterling helped put the financing package together.[38]

Environmental impact

The ACP's proposal claims that the project will not permanently harm the environment, communities, primary forests, national parks or forest reserves, relevant patrimonial or archaeological sites, agricultural or industrial production areas, or tourist or port areas. It says that any harm can be mitigated using existing procedures and technology.[1]

The proposal says that the project will not permanently reduce water or air quality. The proposed water supply program maximizes the water capacity of Gatun and Alhajuela Lakes and is designed to use water efficiently so that no new reservoirs will be required and no communities need to be displaced.[1]

Critics of the project contend that there are many environmental issues to be considered, such as the link between El Niño (ENSO) and the threat to water supplies posed by El Niño. The ACP has commissioned studies by several consultants about water supply and quality problems. Some of the most prominent critics of the canal expansion plan from the point of view of water quality issues are Eric Jackson[39] (editor of the online Panama News), Gonzalo Menendez[40] (former head of Panama's National Environmental Authority), and Ariel Rodriguez[41] (a biologist at the University of Panama), and former Vice Minister of Public Works Grettel Villalaz de Allen.[42]

Jackson contends that the ACP's public statements often do not match the findings of their studies. He argues that studies by Delft Hydraulics,[43] WPSI Inc.,[44] and DHI[45] all say that the proposed water-saving basins will allow more salt water into Gatun Lake, from which about half of Panama's population takes its drinking water. The ACP says that the problem can be reduced by "flushing" the new locks with fresh water from Gatun Lake, but this would defeat the water-saving feature.

However, one of the leading environmental organizations in Panama, the National Association for Nature Conservation (ANCON), says that the studies and projections of operations of the third set of locks, including the water-saving basins, credibly state that there will be very low levels of salinization of waters of Gatun Lake and that these levels will preserve the biological separation of the oceans while safekeeping biodiversity and water quality for human use.[46]

Employment generation

According to the ACP, the canal expansion's impact on employment will first be observed in jobs directly generated by its construction. Approximately 35,000–40,000 new jobs will be created during the construction of the third set of locks, including 6,500–7,000 additional jobs that will be directly related to the project during the peak years of construction. However, officials state that the most important impacts on employment will be medium and long term, and will come from the economic growth brought about by extra income generated by the expanded canal and the economic activities produced by the increase in canal cargo and vessel transits.

The labor required for construction of the third set of locks will be largely done by Panamanians. To ensure the availability of Panamanian labor necessary for the third set of locks project and its connected activities, the ACP and public and private authorities will work jointly to train the required workforce, with sufficient lead time, so that it has the necessary competencies, capabilities, and certifications. The costs of these training programs are included in the cost estimates of the project.[1]

Critics dismiss this as demagogy, noting that according to the ACP's own studies, at the peak of construction there will be fewer than 6,000 jobs created, and that some of these will be highly skilled posts filled by foreigners because there are no Panamanians qualified to fill them.

Among those who oppose the canal expansion proposal is Panama's construction workers' union, SUNTRACS. The union's secretary general, Genaro Lopez, argues that while some construction jobs will be created by the project, the debt that Panama incurs to build a third set of locks will not be defrayed by increased canal usage and thus an increased part of canal revenues will go toward paying the debt, reducing the waterway's contributions to the national government's general fund, in turn reducing the money available for road projects, public schools, police protection, and other government services.

Critics also claim that the project lacks an accompanying social development plan. Then-President Torrijos has since accepted the request to develop one with the mediation of the United Nations Development Programme.[47]

  • The Council on Hemispheric Affairs (COHA) stated in a press release that under the Torrijos government, the expanding Panama Canal will not likely serve the needs of the vast majority of Panamanians. Many of the benefits will be tied to the commercial interests of the country's accountants, bankers, and lawyers, as well as their US counterparts, and world trade. They also say that the administration's rampant corruption and other flaws raise questions about Panama's capacity to supervise such an enormous project.[55] COHA has received some letters pointing out factual errors in its statement, and plans to modify its statement in response.[56]
  • Former President Guillermo Endara and his Vanguardia Moral de la Patria Party,[57] MOLIRENA,[58] a conservative, business-oriented party that normally gets about 10 percent of the vote.
  • Most of the Panamanian left and most of the labor movement, including CONUSI[59] (National Independent Syndicate Union) and FRENADESO[60] (the National Front for the Defence of Social and Economic Rights).
  • Most members of the nationalist Panameñista Party (Grettel Villalaz de Allen and Gonzalo Menendez, mentioned above, and former legislator Gloria Young[61] are prominent examples).
  • Some environmentalist leaders and groups: Biodiversidad Panama, whose principal leader is University of Panama biologist Ariel Rodriguez, and former National Environmental Authority director Gonzalo Menendez.
  • Proponents of Liberation Theology, in part because they suspect that poor farmers among whom they have a social base would be adversely affected. The canal expansion issue has aggravated the breach between this mainly Catholic strain and the Catholic hierarchy.[62]
