- Panama Canal expansion project
The Third Set of Locks Project is a
megaproject that will expand thePanama Canal . The expansion will be greater than at any time since the canal's construction. ThePanama Canal Authority proposed the project after years of study.Panamanian President Martín Torrijos presented the plan onApril 24 ,2006 andPanama nian citizens approved it in a national referendum by 76.8% of votes onOctober 22 ,2006 . The project will double the canal's capacity and allow more traffic.The project will create a new lane of traffic along the Canal by constructing a new set of locks. Details of the project include the following integrated components:
* Construction of two lock complexes — one on the Atlantic side and another on the Pacific side — each with three chambers, which include three water-saving basins;
*Excavation of new access channels to the new locks and the widening of existing navigational channels; and,
*Deepening of the navigation channels and the elevation ofGatun Lake ’s maximum operating level. [http://www.acp.gob.pa/eng/plan/documentos/propuesta/acp-expansion-proposal.pdf "Proposal for the Expansion of the Panama Canal" by the "Panama Canal Authority"] en icon]As stipulated by the Panamanian

September 3 ,2007 the Panama Canal expansion project officially started. Panama's presidentMartín Torrijos stated that the Canal will generate enough wealth to transform Panama into aFirst World country.The president also announced that the canal will also industrialize the country when the expansion projects start progress.Fact|date=September 2007 The project is also expected to reduce poverty by about 30%, making Panama have an estimated 8% of poverty in 2012.
Background
Since the 1930s, all of the Canal widening studies have determined that the most effective and efficient alternative to enhance Canal capacity is the construction of a third set of locks, with bigger dimensions than those of the locks built in 1914. Thus, in 1939, the
United States initiated the construction of locks designed to allow the transit of commercial and war ships, whose dimensions exceeded the size of the existing locks. In 1942, after advancing the excavations significantly, the Americans suspended the third set of locks project due to the outbreak ofWorld War II . In the 1980s, the tripartite commission formed byPanama ,Japan , and theUnited States took up the issue again, and like the Americans in 1939, determined that a third set of locks with larger lock chambers was the most appropriate alternative for increasing Canal capacity. Today, the studies developed by thePanama Canal Authority (ACP) as part of its Master Plan, with a horizon to the year 2025, confirm that a third set of locks, larger than those existing now, is the most suitable, profitable and environmentally responsible way to increase Canal capacity and allow the Panamanian maritime route to continue to grow.Throughout its history, the Canal has continually transformed its structure and adjusted to trade requirements and international maritime transport technologies. In this manner, the Canal has managed to increase its
competitiveness in a sustainable manner.Fact|date=August 2007President Torrijos on his speech on
April 24 ,2006 , announcing the project, said that "…to say it in a graphic manner, [the Canal] is like our 'petroleum '. Just like the petroleum that hasn't 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". [http://www.presidencia.gob.pa/discurso.php?cod=866&tex= President Martín Torrijos's speech at the unveiling of the project] es icon]Cargo volume
Based on ACP's projections, during the next 20 years, cargo volume transiting the Canal will grow at an average of three percent per year, doubling 2005’s tonnage by the year 2025. As such, providing the Canal with the capacity to transit larger vessels will make it more efficient by allowing the transit of higher cargo volumes with relatively fewer transits and less water use.
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 andwheat , among others), minerals, fertilizers, coal, and liquid goods, such as chemical products, propane gas, crude oil and oil derivatives. Recently, thecontainerized cargo segment has replaced the dry bulk segment as the Canal’s main income generator, moving it to second place. On the other hand, the vehicle carriers segment has become the third income generator, replacing the liquid bulk segment. Shipping industry analyses conducted by the ACP and top industry experts indicate that it would be beneficial to both the Canal and its users to expand the Canal due to the demand that will be served by allowing the transit of more tonnage.The question is, however, whether the trend upon which the
Panama Canal Authority makes those projections can continue for a generation. The growth inPanama Canal usage over the past few years has been almost entirely driven by increased U.S. imports fromChina passing through the canal to ports on the U.S. East and Gulf Coasts. But it is increasingly recognized in both the United States and China that this imbalance in trade is unsustainable and will be reduced in some sort of adjustment in the coming years, [ [http://worldnews.about.com/od/china/a/china_trade.htm Why the U.S. China Trade Imbalance is Unsustainable by About.com] ] though it is important to note that any such 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 it will not only not be adjusted, but will continue to grow for a generation as it has for the past several years. One of the central points of the canal expansion proposal's critics, most prominently made by former canal administrator Fernando Manfredo, is that it's unrealistic to attempt to predict canal usage trends over a generation, most improbable to expect that U.S. imports from China will continue to grow as they have the past few years over a generation, and irresponsible to bet Panama's financial future on such a projection.Competition
The most direct competition to the Canal is from alternative routes which present options for the transport of cargo between the same geographical points of origin and destination. The two main competitors of the Panama Canal are the U.S. intermodal system and the
Suez Canal .According to the ACP, the growing trend to use Post-Panamax
container ship s in transcontinental routes competing with the canal is irreversible. The main ports and merchandise distribution centers in these routes are investing in capacity, location, and maritime and land infrastructure to serve these vessels and handle their cargo volumes. If this trend continues, by the year 2011, approximately 37% of the capacity of the world’s container ship fleet will consist of vessels that do not fit through the canal, and a great part of this fleet will be placed in routes that compete with Panama, such as the transpacific-intermodal route and theSuez Canal route.The proposal states that strengthening its competitive position will allow the canal to accommodate demand and serve its customers. If the canal were to have the capacity to serve the growing demand, Panama could be transformed into the most important connectivity hub in the continent by joining together at the isthmus the north-south continental routes with the 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 one of the main world trade routes.
Predictions
According to the ACP, the Canal will reach its maximum sustainable capacity between the years 2009 and 2012. When it reaches this capacity it will not be able to continue to handle demand growth, 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 2014. All creative means will be employed by the ACP to stretch capacity until the construction is done.
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 have approximately double the capacity of the present Canal.
Critics such as former legislator Dr. 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, in which there is a limited capacity for large ships to pass one another [ [http://aol.countrywatch.com/aol_printwire.asp?vCOUNTRY=133&UID=1375565 Analysis: Expanding the Panama Canal By INGRID VASQUEZ] ]
Although the Canal is reaching its maximum capacity, the ACP clarifies that this does not mean that ships will be unable to transit the Canal. However, it does mean that the Canal’s growth capacity will stagnate and that it will not capture additional cargo volumes.
The former head of the Panama Canal's Dredging Division, Thomas Drohan, who is 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, any business can raise its price for it and this would apply to Panama Canal tolls as much as it does to petroleum [ [http://www.thepanamanews.com/pn/v_12/issue_17/news_02.html The “no” campaign holds a forum by Eric Jackson] ] .
The project
Locks
The Canal proposal today has two lanes each with its own set of locks. The proposal consists of adding 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 to the southwest of the existing Miraflores Locks. The other complex will be located to the 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 ofGatun Lake and back down again. Each chamber will have three lateral water-saving basins, for a total of nine basins per lock and 18 basins total. Just like the existing locks, the new locks and their basins will be filled and emptied bygravity , without the use ofpumps . 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 the start of World War II. The new locks will be connected to the existing channel system through new navigational channels.The new lock chambers will be 427 meters (1,400 ft) long, by 55 meters (180 ft) wide, and 18.3 meters (60 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 well-proven technology. The new locks will use
tugboat s to position the vessels instead of locomotives. As in the case of the rolling gates, tugs are successfully and widely utilized for these purposes in locks of similar dimensions.Navigational channels
According to the plan, a 3.2 km-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 north access channel, which will connect the new Pacific-side lock with the
Gaillard Cut , circumventing Miraflores Lake, and which will be 6.2 km long; and,* The south access channel, which will connect the new lock with the existing sea entrance on the
Pacific Ocean , and which will be 1.8 km long (see figure 5). The new channels will be at least 218 meters (715 ft) wide, both on the Atlantic and Pacific sides, which will permitPost-Panamax vessels to navigate in these channels in a single direction at any time.Gatun Lake raised convert|1.5|ft|m
All Canal elevations are referred to Precise Level Datum (PLD), which is close to Atlantic and Pacific entrance mean sea level. The maximum operational level of
Gatun Lake will be raised by approximately 0.45 meters (1.5 ft) — from the present PLD level of 26.7 meters (87.5 ft) to a PLD level of 27.1 meters (89 ft). Combined with the widening and deepening of the navigational channels, this component will increase Gatun Lake’s usable water reserve capacity and will allow the Canal’s water system to supply a daily average of 165 million gallons (625 million liters) 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 provided from Gatun and Alhajuela Lakes.Construction timeline
The construction of the third set of locks project is slated to take between seven to eight years. The new locks could begin operations between fiscal years 2014 and 2015.
Finances
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 both in increased cargo volume and vessel size that will use the Panama route. In this sense, the Canal, with a third set of locks, will be able to manage the traffic demand forecast beyond 2025, and total revenues for that year, adjusted for inflation, will amount to over USD $6.2 billion.
Estimated cost
The cost to construct the third set of locks is estimated by the ACP at approximately USD $5.25 billion. This estimate includes design, administrative, construction, testing, environmental mitigation, and commissioning costs. Additionally, this cost includes contingencies to cover risks and unforeseen events, such as those that might be caused by accidents, design changes, price increases, and possible delays, among others. The most relevant program cost is that of constructing the two new lock complexes — one on the Atlantic side and the other on the Pacific side — with estimated costs of approximately USD $1.110 billion and USD $1.03 billion each, plus a USD $590 million provision for possible contingencies during their construction.
Opponents contend the project is based on uncertain projections about maritime trade and the world economy. Prof. R.N. Mendez, an economist who works for the
University of Panama , alleged that the economic and financial projections are based on manipulated data. [http://www.nodo50.org/caminoalternativo/canal/43.htm "A bad business for Panama" by Roberto Mendez] es icon] Independent engineers, most notably Humberto Reynolds [http://www.nodo50.org/caminoalternativo/canal/33.htm "Estimated cost of the Third Locks" by Humberto Reynolds] es icon] and Tomas Drohan Ruiz, [http://www.nodo50.org/caminoalternativo/canal/83.htm "The real cost of the expansion" by Tomas Drohan Ruiz] es icon] 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, professor at the University of Panama thinks that confidence in the budget of the Panama Canal Authority is undermined because of engineering and consultancy firm Parsons Brinckerhoff's involvement. Parsons Brinckerhoff is best known for the Boston Big Dig, which ended up costing three times the estimated amount with several structural and safety concerns. [http://www.nodo50.org/caminoalternativo/boletin1/127-3.htm "The 'Big Dig' of the expansion" by M.A. Bernal] es icon]
Estimated profit
According to the ACP, the third set of locks is financially profitable, producing a 12% internal rate of return. The third set of locks project is self-financed and its financing will be separate from the Government’s financing. The state will not guarantee or endorse any loans undertaken by the ACP for the project’s execution. With tolls increasing at an annual average rate of 3.5% for 20 years, and according to the most probable traffic demand forecast and construction schedule, the external financing required will be mainly temporary and on the order of USD $2.3 billion to cover peak construction activities between 2009 and 2011. With the cash flows generated by the expanded Canal, investment costs will be recovered in less than 10 years and financing could be repaid in approximately eight years.
What "self-financing" actually means, however, is disputed. At least half of the money needed for the canal expansion project will have to be borrowed, and the ACP does not calculate the interest on that as part of the project's costs.Fact|date=February 2007
The ACP's revenue projections are based on suppositions about increase in canal usage and the willingness of shippers to pay higher tolls instead of seeking competing routes, both of which critics question.
Environmental impact
The ACP claims in the proposal that the third set of locks project is environmentally viable. It has been found that all possible adverse environmental impacts can be mitigated through existing procedures and technology, and no immitigable or permanent adverse impacts on the population or the environment are anticipated. There are no elements within the scope of the project that will compromise its environmental viability, such as communities, primary forests, national parks or forest reserves, relevant patrimonial or archaeological sites, agricultural or industrial production areas, or tourist or port areas. The project will not cause permanent or irreversible impacts on water or air quality. The proposed water supply program fulfills the objectives of maximizing the water capacity of Gatun and Alhajuela Lakes, and applies the most efficient water utilization technology at the locks so no new reservoirs will be required. Consequently, it will not be necessary to relocate communities. The entire area directly affected by the project is located within ACP operational and administrative areas.
Critics to the project contend there are a lot of environmental topics to be considered. For example: link between El Niño (ENSO) and global warming threat to water supplies. The ACP has commissioned a number of studies by a number of consultants about water supply and quality issues, and some like Eric Jackson [http://www.thepanamanews.com/pn/v_12/issue_12/business_01.html Propaganda, studies differ about Gatun Lake water quality by Eric Jackson] en icon] (editor of the Panama News internet newspaper), Gonzalo Menendez [http://www.thepanamanews.com/pn/v_12/issue_14/opinion_01.html Some worrisome environmental aspects of the Panama Canal expansion by Gonzalo Menendez] ] (former head of the National Environmental Authority or ANAM by its Spanish initials), Ariel Rodriguez [http://www.thepanamanews.com/pn/v_12/issue_13/spanish_opinion_03.html Panama News Spanish Opinion Section] es icon] (University of Panama biologist), former Vice Minister of Public Works Grettel Villalaz de Allen [ [http://www.nodo50.org/caminoalternativo/canal/24.htm Buscando Camino -Especial Canal - El agua del Canal de Panamá ] ] and others are some of the most prominent critics of the canal expansion plan from the point of view of water quality issues. Jackson contends that ACP's public statements often do not match the findings of their studies. He says that the Delft Hydraulics, [http://www.pancanal.com/esp/plan/estudios/0238.html Delft study on the water quality] ] WPSI Inc, [http://www.pancanal.com/esp/plan/estudios/ep-0024.html WPSI study about the water] ] and DHI [http://www.pancanal.com/esp/plan/estudios/0276.html DHI "study of studies"] ] studies all say that no matter what is done to mitigate the problem, the water saving basins feature of the proposed new locks would increase the intrusion of salt water into Gatun Lake, from which about half of Panama’s population takes its drinking water. The chosen method to partially mitigate this problem is to "flush" the new locks with fresh water from Gatun Lake — but that tends to defeat the proposed new locks’ water saving feature and raises questions about the security of the urban water supply.
However, one of the leading environmental organizations in Panama, ANCON (National Association for Nature Conservation) says that the studies and projections of operation of the Third Lock, including the water saving basins, state in a credible manner that there will be very low levels of salinization of waters of
Gatun Lake and that these levels would preserve the biologic separation of the Oceans with the safekeeping of the biodiversity and water quality for human use. [http://www.ancon.org/mambo/index.php?option=com_content&task=view&id=117&Itemid=150 ANCON approves the proposal] es icon]Employment generation
According to the ACP, the Canal expansion’s impact on employment will first be observed in the jobs directly generated by the economic boom experienced during the years of its construction. Approximately 35,000 to 40,000 new jobs will be created during the construction of the third set of locks, including 6,500 to 7,000 additional jobs that will be directly related to the project during the construction’s peak years.
However, officials state that the most important impact 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 – all of these contributing to fully leverage the advantages of Panama’s geographic position.The labor required for construction of the third set of locks will, in its vast majority, be 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 amounts necessary to carry out these training programs are included in the cost estimates of the project.
Critics dismiss this as pure
demagogy , noting that by 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 who are qualified to fill them.Fact|date=February 2007Among 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 would be created by the project, the debt that Panama incurs to build a third set of locks would not be defrayed by increased canal usage and thus an increased part of canal revenues would go toward paying the debt, reducing the waterway's contributions to the national government's general fund and in turn reducing money for road projects, public schools, police protection and all other government services.Fact|date=February 2007Critics also claim the project lacks an accompanying social development plan. President Torrijos has since accepted to develop one with the mediation of the
UNDP . [http://www.undp.org.pa/DesktopModules/Articles/ArticlesView.aspx?TabID=0&Lang=es&ItemID=246&mid=10334 Press release of the UNDP-Panama about the mediation process] es icon]Voices supporting the project

The logic behind this is that said port would be the second port (the first being Los Angeles) deep enough in the American Pacfic capable of handling post-panamax ships. As Panama is already a natural trading route, it would be able to handle the movement of containers from the Pacific to the Atlantic side via railroad, where containers would be reloaded to other ships for worldwide distribution.
