Valemax ships are a fleet of very large ore carriers (VLOC) owned or chartered by the Brazilian mining company Vale S.A. to carry iron ore from Brazil to European and Asian ports. With a capacity ranging from 380,000 to 400,000 tons deadweight, the Chinamax ships are the largest bulk carriers ever built and among the longest ships currently in service.
In 2008, Vale placed orders for twelve 400,000-ton Valemax ships to be constructed by Jiangsu Rongsheng Heavy Industries (RSHI) in China and ordered seven more ships from South Korean Daewoo Shipbuilding & Marine Engineering (DSME) in 2009. In addition sixteen more ships of similar size will be built in China and South Korea for other shipping companies, and chartered to Vale under long-term contracts.

Jiangsu Rongsheng Heavy Industries
The first Valemax vessels were ordered on 3 August 2008 when Vale signed a contract with the Chinese shipbuilder Jiangsu Rongsheng Heavy Industries (RSHI) for the construction of twelve 400,000-ton ore carriers. The development had reportedly started in 2007. The contract, worth $1.6 billion, was the world's biggest single shipbuilding contract by deadweight tonnage. The first Chinese-built Valemax vessel, Vale China, was launched at the Nantong shipyard on 9 July 2011 and delivered on 25 November 2011. Although it was expected that the first Chinese-built Valemax vessel would call a Chinese port on its maiden voyage, the ship was diverted to the new transshipment hub Vale had constructed in Philippines. The second RSHI-built Valemax ship (Vale Dongjiakou) was delivered on 9 April 2012, the third (Vale Dalian) on 20 May, the fourth (Vale Hebei) on 28 September, the fifth (Vale Shandong) on 7 December 2012, the sixth (Vale Jiangsu) on 23 March 2013, the seventh (Vale Caofeidian) on 22 July 2013, and the eight (Vale Lianyungang) on 22 November 2013. In March 2012, the shipyard announced that all but one of the remaining Valemax vessels ordered by Vale would be delivered within 2012, but according to Vale only two more ships would be delivered. As of December 2013[update], at least one more RSHI-built Valemax ship (Vale Majishan) has been launched.
On 2 November 2008, Oman Shipping Company signed a framework agreement with RSHI for the construction of four 400,000-ton vessels to transport iron ore from Brazil to the port of Sohar in Oman, where Vale is expected to open a steel plant in near future. The shipbuilding contract, worth US$483 million, was signed in July 2009. Initially the ships were to be named Jazer, Yanqul, Al Kamil and Wafi, but instead they will be named Vale Liwa, Vale Sohar, Vale Shinas and Vale Saham. The steel cutting ceremony for the first two vessels was held on 8 July 2010 and they were launched on 19 March 2012. Vale Liwa entered service in August 2012, followed by Vale Sohar in September 2012, Vale Saham in January 2013, and Vale Shinas in March 2013. The ships reportedly received additional strengthening due to the Vale Beijing incident. As of December 2012[update], the ships built for Oman Shipping Company have been removed from the Det Norske Veritas registry.
The Chinese shipbuilder's ability to deliver any of the very large ore carriers ordered by Vale in time was doubted already before the first ship was built. In May 2011 it was announced that due to delays in construction only two or three Valemax vessels will be delivered from the Chinese shipyard in 2011 instead of the planned six. In the end only one ship, Vale China, was delivered in before the end of the year. Furthermore, later reports claimed that the ships ordered by Vale have a capacity of only 380,000 tons, even though according to the Det Norske Veritas database entries all Chinese-built ships have a deadweight tonnage in excess of 400,000 tons and in the past Vale has referred to the ships ordered from Rongsheng as 400,000-ton vessels. The reduction in cargo capacity, at least on paper, may be due to the reluctance of Chinese officials to accept the 400,000-ton ships to Chinese ports.
In April 2012 it was reported that Vale had refused delivery for three Valemax ships recently completed by Jiangsu Rongsheng Heavy Industries. This was seen as a move against the Chinese officials who have not allowed the 400,000-ton ships to dock in Chinese ports. However, the reports were rebutted by RSHI, who called them "inaccurate and unfounded".
Daewoo Shipbuilding & Marine Engineering
On 26 October 2009 Vale ordered four Valemax vessels from the South Korean shipbuilder Daewoo Shipbuilding & Marine Engineering (DSME) for $460 million. Further three ships were ordered from DSME in July 2010, bringing the total order to seven 400,000-ton Valemax vessels. Despite receiving the order later than the Chinese shipyard, DSME launched the first Valemax class ore carrier, Vale Brasil, on 31 December 2010 and delivered her to Vale in March 2011. It was followed by Vale Rio de Janeiro on 22 September 2011, Vale Italia on 25 October 2011, Vale Malaysia on 27 March 2012, Vale Carajas on 29 May 2012. and Vale Minas Gerais on 13 July 2012. The last Valemax ship to be built by DSME, Vale Korea, was delivered on 9 April 2013.
STX Offshore & Shipbuilding
In addition to the ships Vale ordered for itself, further sixteen ships of similar size will be built for other shipping companies and chartered to Vale under exclusive long-term contracts, bringing the total fleet under Vale to 35 vessels. Eight of the ships will be built by South Korean shipbuilder STX Offshore & Shipbuilding in Jinhae, South Korea (STX Jinhae), and Dalian, China (STX Dalian). The shipping company, STX Pan Ocean, signed a 25-year contract with Vale in 2009.
The first STX-built Valemax vessel, Vale Beijing, was delivered by STX Jinhae on 27 September 2011. Although another vessel was expected to take delivery later that year, only one ship was delivered. The second ship, Vale Qingdao, was delivered also by STX Jinhae on 13 April 2012, but the third and fourth ships, Vale Espirito Santo and Vale Indonesia, were built by STX Dalian and delivered on 17 September 2012 and 30 October 2012, respectively. However, the fifth ship, Vale Fujiyama, was again built by STX Jinhae and delivered on 26 November 2012. The sixth ship, Vale Tubarao, was delivered by STX Dalian on 30 January 2013. While both of the two remaining ships were supposed to be delivered by the end of 2013, only Vale Maranhao entered service on 29 August. The last Valemax vessel built by STX, Vale Ponta da Madeira, will be delivered in 2014.
Bohai Shipbuilding Heavy Industry
On 30 April 2007 Berge Bulk signed a contract with the Chinese shipbuilding company Bohai Shipbuilding Heavy Industry for the construction of four 388,000-ton very large ore carriers. Although initially scheduled for delivery in 2010, the first vessel, Berge Everest, was delivered on 23 September 2011. It was followed by Berge Aconcagua on 15 March 2012 and Berge Jaya on 12 June 2012. The remaining ship, Berge Neblina, was initially also scheduled to be delivered in 2012, but entered service on 4 January 2013.
Had Vale not ordered the Valemax fleet in 2008, these ships would have become the largest bulk carriers in the world, surpassing Berge Bulk's own Berge Stahl. The four ships have since been chartered by Vale and, despite slight differences in design and contract date predating that of the ships ordered by Vale, they are also referred to as Valemax vessels.
On 24 May 2011, Vale Brasil received her first cargo at the Brazilian port Terminal Marítimo de Ponta da Madeira, 391,000 tons of iron ore bound for Dalian in China. However, in June, after rounding the Cape of Good Hope, the ship was rerouted to Taranto, Italy, and turned back towards the Atlantic Ocean. There had been speculation that Vale Brasil was not allowed to enter the Chinese port fully laden, but according to Vale the destination was changed due to commercial, not political reasons. The ship arrived at the port of Taranto on 14 July 2011 to discharge her cargo. Since then, fully laden Valemax vessels have unloaded at various ports, such as Dalian in China, Sohar in Oman, Rotterdam, Ōita in Japan, Dangjin in South Korea, and the transshipment hub Vale has constructed at Subic Bay in the Philippines.
On 31 January 2012 the Ministry of Commerce of the People's Republic of China officially banned dry bulk carriers with capacity exceeding 300,000 tons from entering Chinese ports to protect the domestic freight industry. Prior to this only one of the new very large ore carrier chartered by Vale, Berge Everest, had unloaded Brazilian iron ore at a Chinese port — the ship arrived at Dalian on 28 December 2011 — but this is assumed to be a bureaucratic fluke as no Chinese port has regulatory approval to receive dry bulk carriers of that size. According to Vale the discussions about allowing the Valemax ships to enter Chinese ports are ongoing and the Chinese officials have given a preliminary go-ahead for the construction of new berths capable of accommodating the 400,000-ton ships. However, according to the Ningbo Port Company, the construction of the new port facilities would take two to three years, causing further delays for Vale which in the meantime is losing $2–3 per ton of ore due to the ban. On 15 April 2013, Vale Malaysia became the first 400,000-ton Valemax vessel to call a Chinese port. The partially loaded ship docked at the port of Lianyungang en route from the Vale transshipment hub in Subic Bay, Philippines. However, it is unclear if the Chinese officials have actually lifted the ban for fully laden Valemax vessels as none of the ships have called Chinese ports since.
Initially Vale planned to own and manage a fleet of 19 Valemax vessels by itself to control the wildly fluctuating charter prices for large bulk carriers, which had dropped from US$233,988 per day in June 2008 to as low as US$2,400 by December of the same year. However, because of the global economic downturn and the reluctance of Chinese ports to accept the fully laden ships due to environmental concerns, the new board of directors decided to focus capital allocation to mining. As a result Vale has reportedly decided to sell the ships to other, likely Chinese shipping companies and charter them back under long-term contracts. On 21 December 2011 a Brazilian financial newspaper reported that Vale had sold the four Valemax vessels that had been delivered by then to an undisclosed buyer and intended to put the remaining 15 on sale before the end of the year, but as of April 2013[update] none of the ships have not changed owners officially. Although Vale may suffer financial losses from selling the ships, they will be covered by the profit from iron ore sales even at current, depressed ore prices if one or two shipments can be unloaded in Chinese ports.
On 1 November 2013, Vale signed a $500 million contract with the Chinese shipping company Shandong Shipping for the operation of four Valemax vessels. As a result, the 400,000-ton ore carriers may finally be able to dock at Chinese ports. The 2011-built Vale Rio de Janeiro was renamed Shandong Da De. She was followed by the 2012-built Vale Minas Gerais (renamed Shandong Da Zhi), Vale Malaysia (renamed Shandong Da Ren) and Vale Carajas (renamed Shandong Da Cheng).
Structural failure of Vale Beijing
On 5 December 2011 it was reported that Vale Beijing, operated by STX Pan Ocean, had suffered structural damage during her first cargo loading and was in danger of sinking at the port of Ponta da Madeira in Brazil due to sea water entering ruptured ballast tanks and cargo holds. The South Korean-built Valemax ship, partially loaded with 260,000 tons of iron ore, was towed away from Pier 1 by tugboats in the following day and as a precaution against environmental damage the Brazilian authorities requested her fuel tanks to be emptied. Since there are no facilities to unload iron ore from the ship at Ponta da Madeira and no large shipyards in the region, emergency repairs had to be performed by divers and the cargo redistributed while the ship is anchored offshore before it could be towed to a shipyard. The cause of the damage has not been published by STX, but design or construction flaws, material fatigue and incorrect loading have all been suspected. According to calculations performed by DNV the damage was not caused by global strength issues or single pass loading, but is assumed to be related to local buckling strength in some areas of the web frames in the aft ballast tanks. Vale Beijing remained anchored off Ponta da Madeira with a crawler crane on the deck and an oceangoing tug standing by until 19 February 2012, when it left São Luís for Oman. After unloading at Sohar, the ship headed to South Korea for dry docking and arrived at STX shipyard in Jinhae, where it was delivered in September 2011, for inspection and repairs on 21 April 2012. Vale Beijing returned to service in July 2012.
Had Vale Beijing sunk at the pier instead of being moved to an anchorage area outside the port shortly after the leak was detected, the incident would have severely delayed the operations at the port which ships out about 10 percent of the world's iron ore production. While Vale Beijing delayed the loading of only 750,000 tons of iron ore, on 11 November 1994 Trade Daring, a 145,000 DWT ore-bulk-oil carrier, broke in two at the same location due to incorrect loading, blocking the deepwater pier of Ponta da Madeira for more than six weeks before the wreck was removed and scuttled offshore.
After the incident, the China Shipowners' Association (CSA) questioned the safety of the 400,000-ton ore carriers commissioned by Vale. CSA was particularly concerned about the ability of the newly built ships to withstand various sea conditions and the pollution resulting from fuel oil leaks in case of structural damage — each Valemax ship can carry around 10,000 tons of fuel oil. In January 2012 China officially banned the vessels from Chinese ports. However, in April 2013, The China Shipping Association confirmed that the first Valemax vessel was allowed to dock in the Chinese port of Lianyungang in the Jiangsu province. Despite this, the ban has not been officially lifted as of September 2013[update].
Grounding of Vale Indonesia
On 7 September 2013, Vale Indonesia ran aground on a sandbar about 40 nautical miles (74 km; 46 mi) north of São Luís. The vessel, operated by STX Pan Ocean, was fully laden with 390,000 tons of iron ore bound for Vale's transhipment hub in Subic Bay. Two ballast tanks were reportedly breached, but there were no injuries or pollution, and the vessel was not in danger of sinking.
Although similar in size, the Valemax vessels built by different shipyards in South Korea and China have some differences in main dimensions, cargo capacity, machinery and external appearance.
The Valemax ships are 360 to 362 metres (1,181 to 1,188 ft) long, making them some of the longest ships currently in service. With a maximum draught of between 22 and 23 metres (72 and 75 ft) while loaded, the ships are limited only to a few deepwater ports in Brazil, Europe and China. In ballast the ships draw around 12 metres (39 ft) of water. The breadth of the Valemax ships is about 65 metres (213 ft). The size of the ships is limited mainly by Chinese ports and the ships of this size are generally referred to as Chinamax vessels.
The Valemax vessels have seven cargo holds with a total gross volume of almost 220,000 cubic metres (287,749 cu yd). In addition to increasing the strength of the hull special attention has also been paid to improve the speed and efficiency of the loading and discharging operations. Each cargo hold can be fully loaded by a shiploader in a single step with a loading rate of 13,500 tonnes per hour and can carry almost as much iron ore as a small Panamax carrier. In addition the space inside the cargo hold that cannot be reached by grabs during discharging, the so-called "dead spots", is minimized. With a deadweight tonnage of 400,000 tons, a fully laden Valemax vessel is carrying as much iron ore as around 11,150 trucks, enough to produce steel for three Golden Gate bridges. Once all 35 Valemax ships are in service and if each ship does four round trips per year, they will be capable of carrying about 15% of the annual iron ore exports from Brazil to all destinations.
Like most modern bulk carriers, each Valemax vessel will be powered by a single two-stroke low-speed crosshead diesel engine directly coupled to a fixed-pitch propeller. The ships built by DSME and STX in South Korea will be powered by 7-cylinder MAN B&W 7S80ME-C8 and 7S80ME-C engines, respectively, and the ships built by RSHI and Bohai Shipbuilding Heavy Industry will receive Wärtsilä 7RT-flex82T and 7RT-flex84T engines, respectively. The Wärtsilä RT-flex82T engines are manufactured in China under licence. Both MAN and Wärtsilä engines will have a maximum continuous rating of around 29,000 kW (39,000 hp) when turning the 10-metre (33 ft) propeller at 76–78 rpm, giving the ships a service speed of around 15 knots (28 km/h; 17 mph) while burning almost 100 tons of heavy fuel oil per day. However, due to the large size of the vessels the emissions per cargo ton-mile are very low and thus the Valemax vessels are in fact among the most efficient long-distance dry bulk carriers in service — Vale has reported a 35% drop in emissions per ton of cargo carried in comparison to older ships.
All Valemax vessels will be classified by Det Norske Veritas, although some have dual classification with the Korean Register of Shipping. However, the Valemax vessels built for Oman Shipping Company have been removed from the DNV database.
The new ships are considerably larger than the previous record holder, 364,767-ton Berge Stahl, which had been the largest bulk carrier in the world since it was built in 1986. While the draft of the old vessel is the same as that of the Valemax vessels — 23 metres (75 ft) — the new ships are 20 metres (66 ft) longer and 1.5 metres (4.9 ft) wider than the old freighter, and can carry about 10% more cargo.
The Valemax vessels are also the second largest ships in service by deadweight tonnage, second only to the TI class supertankers that have a deadweight tonnage of over 440,000 tons. However, they are still far from the largest ship ever constructed — Seawise Giant, built in 1979 and broken up in 2009, was 458.46 metres (1,504.1 ft) long and had a deadweight tonnage of 564,650 tons — and also considerably shorter than the longest ships currently in service, the 399-metre (1,309 ft) Mærsk Triple E class container ships.
Vale's decision of constructing a fleet of 400,000-ton ore carriers has been widely criticized by other shipping companies. The new Valemax ships, expected to cut the company's transportation costs by 20–25%, are blamed for driving down the freight rates for the entire industry, swelling the already oversupplied bulk transportation market and stalling the recovery of the shipping business after the financial crisis.
The freight rates, down 80% from 2008, are expected to drop further down to the levels of 1977. According to the chief executive of BIMCO, the Valemax vessels could displace up to 168 150,000–180,000-ton capesize bulk carriers, around 15% of the existing fleet, from the long haul voyages and force them to less profitable shorter routes. Vale has responded to the criticism by stating that the company aims to permanently cut the costs of Atlantic-Pacific dry bulk shipping to make Brazilian ore more competitive against iron ore produced in Australia, which is closer to major customers in Asia.
Vale has also faced opposition from the China Shipowners' Association which claim that the Brazilian mining company is seeking to control the freight market as it has already done with the iron ore prices. In the past the Chinese ports were not allowed to increase their capacity to more than 300,000 tons for dry bulk carriers due to safety and environmental concerns, and if the 400,000-ton Valemax vessels are allowed to Chinese ports, Vale's monopoly on the route may result in losses for other shipping companies operating capesize ore carriers. Also, when Vale Brasil was diverted to Italy on her maiden voyage, there was speculation that the domestic steel industry of China had urged the authorities to protect their commercial interests. However, Vale has also received support from the Chinese steel companies as they would benefit from lower transportation costs.
As a precaution against prolonged ban of Valemax vessels from the Chinese ports, Vale started constructing both land- and offshore-based transshipment hubs where iron ore can be loaded to smaller ships for final delivery. Ore Fabrica, a 280,000 DWT crude oil tanker converted in China, arrived at Subic Bay, Philippines, in late January 2012 and has since unloaded a number of Valemax ships. This backup plan has also been criticized by the vice-executive chairman of the CSA, Zhang Shouguo, who called it "waste of resource" and questioned Vale's ability to run the fleet as properly as professional shipping companies. There have been rumors that as a result Vale intends to sell or lease its planned fleet of Valemax bulk carriers to Chinese shipping companies with long-term charter contracts to avoid such criticism and allow the ships to enter Chinese ports, but as of 2013[update] no Valemax ship has changed owners.
In May 2012, the largest Chinese operator of dry bulk carriers, state-owned China Ocean Shipping (Group) Company (COSCO), claimed that Vale has refused to use the company's ships since March as a protest against banning the Valemax vessels from Chinese ports. Vale has refused to give comments on the issue.
Luiz Inácio Lula da Silva, the former president of Brazil, also publicly criticized Vale's former CEO Roger Agnelli for the decision of ordering ships from Asian shipyards instead of building them in Brazil, where Lula da Silva has been trying to revitalize the shipbuilding industry to create more jobs and increase local demand for steel and other products. Agnelli, who later left his position following continued criticism, replied that the Brazilian shipyards did not have the capacity to build such ships and stated that during the past few years Vale had commissioned 51 vessels from Brazilian shipyards.
