Since the replacement of the engine, fuel and construction materials, in recent years the Gulf of Mexico marine ship has become more energy efficient and less polluting. At the same time, the Gulf of Mexico shipyard has new requirements for regulatory and users responded.
harvey gulf international environmental regulations ship coordinator nicole eddlemon pointed out that "in the United States, the use of energy-efficient vessels is subject to the Obama Administration and the US Environmental Protection Agency launched the North American Emission Control Area regulations or eca driven also by oil and gas platforms stringent emissions requirements drive, clients who are trying to become more environmentally friendly ship operators to save energy. "
According harvey gulf international deepwater Alaska and chad verret senior vice president of operations, in all the ship 200 miles off the coast within the United States, must meet the requirements of low-sulfur fuel EPA August 1, 2012 came into force, "in fourchon marine fuels sold in Hong Kong are now low-sulfur diesel fuel. "
harvey gulf: the more stringent standards? no problem!
Permitted sulfur content in diesel has dropped to 10000ppm, in 2015 will fall to 1000 ppm. Non-current limit global emissions control area is 35000 ppm. However, harvey gulf of verret insists, "This new EPA rules will not affect our LNG carriers, LNG because almost no sulfur. For example, in 2013 we will deliver the US Gulf market The lng osv would not be affected. "
Today the vast majority of energy are concentrated in the engine. eddlemon noted that "due to the improved engine power configuration, we recently delivered the ship's diesel engine tier ii, can reduce emissions and optimize fuel consumption. In 2011 and 2012, we have delivered three 300 multipurpose dps-2 diesel-electric propulsion osv, have been leased out. "November 2011, harvey gulf delivered" harvey supporter "number, in April 2012 delivered" harvey sisuaq "number, in August 2012 delivered the" harvey champion "No. .
US deepwater Gulf of Mexico to introduce lng supply vessels
In mid-August 2012, harvey gulf lng osv signed three long-term lease contract, which is the first US company signed lng supply vessels in the US deep water. This 3 "harvey energy" number, "harvey power" number, "harvey liberty" number will be delivered in 2013 and 2014.
eddlemon pointed out that "the UK North Sea is very environmentally friendly, the area has been used for many years lng ship, action faster than the United States." She also mentioned that the sulfur content of diesel fuel in California limits are more stringent than in North America eca restrictions. California on the sulfur content of marine diesel emissions limit of 5000ppm.
eddlemon said, "One of the reasons we accelerate the use of lng ship because of the offshore platforms made very strict emissions requirements." eddlemon said that if the annual emissions rigs EPA provisions of the outer continental shelf area of over 250 tons, which is the main source of internet. "These platforms owner must determine what their primary pollution, including nox, sox and carbon dioxide, and using the best control technology (bact) or bact analysis."
eddlemon also noted that "some platforms, according to their permitted emission limits allow the ship to burn only low-sulfur fuel, and only close to the platform for a limited time." She said, lng almost no sulfur, rarely as bunker fuel emissions The nox.
thoma-sea meet environmental requirements
When thoma-sea marine constructors, llc started building can reduce diesel emissions and fuel - electricity osv time, the market demand for the company responded. The company is building a series of diesel - electric osv. Walter thomassie general manager, explains, "Compared with the traditional design, they will be optimized hull design to reduce emissions on the basis of power system efficiency, and significantly reduce fuel consumption." These ships have gained abs, ams, a1, circle e , enviro, dp-2, fifi-1, uscg sub i & l certification.
The series first ship will be delivered by the end of 2012, in July 2013 the delivery of the second ship, and ship delivery in September 2013, the first four in January 2014 delivery. thomassie pointed out, "When we started this project at the end of 2010, our shipbuilding decision was driven by market demand. At design time, our customers and gulf offshore logistics company considers it necessary for the marine areas to provide an efficient and environmentally friendly solutions choice. The concept is the same technology associates, inc Company (tai) designed in cooperation. "
2010, thoma-sea will integrate its lockport and houma into thoma-sea marine constructors. Recently, the company sold two diesel - electric power psv to gulf mark americas.
bordelon companies use emissions engine
According bordelon marine inc. Is building three 252 feet long psv, boat engines will reduce pollution emissions. The company's president and chief executive officer wes bordelon introduction, "we began designing in 2010. Even if this requirement was not, but we decided to build tier 3 emission standards in line with the new boat." EPA tier 3 requirements and reducing nox other emissions. stringrays design propulsion system will be 2 Cummins qsk 60-m, in line with the requirements of tier 3 engines, each driving a station schottle 1215,220 hp z-drive. Each ship will be equipped with two schottle stt2,1020 hp bow thruster.
bordelon said, "These stringray design, the level abs solas, l & i, accu, fifi 1, dp2, ams ship using special software, the combination of large and small generators to maximize fuel efficiency. When demand is low, the ship Alternatively a single low-power generator to run. "The first ship will be delivered in January 2013, the second ship to be delivered in September 2013, the third ship in January 2014 delivery.
bordelon marine oil and gas industry, the Gulf of Mexico and around the world to provide transport services. bmi offers marine vessels, to support the construction, exploration, production and rov and diving, marine research and military applications.
riverhawk using lightweight materials to reduce energy consumption
"High-performance patrol boat builders riverhawk fast sea frames, using environmentally friendly materials production of military ships and maritime security," the company said engineer fabrizio loi. In early August 2012, the company built 43 meters long, advanced multi-mission platform (amp) has completed sea trials in the Gulf of Mexico received. riverhawk the use of advanced composite materials instead of the traditional steel and aluminum, high-speed patrol boats, including amp and seastriker series boat hull, deck and superstructure provides strength, rigidity and firmness.
loi noted that optimize weight composite construction can improve the performance of ship operators and ship operators to reduce the impact on the environment. "The benefits of weight reduction to increase the load in the case of the same tonnage, which will help reduce carbon dioxide emissions unit load. If the load increases are not concerned, it can also reduce the demand for power, reducing fuel consumption and reduce carbon dioxide emission."
james jones composites consulting group (ccg) regional manager for the Americas, "amp45 in the development process, we and riverhawk and a contractor cooperation, we have consulted the use of vacuum infusion manufacturing composite hull. In order to provide a lightweight boat, structure sturdy hull, we use the whole ship diab foam structure of the core material. "ccg diab group is a branch, to provide the core structural materials for the shipbuilding, aerospace, transportation and other markets.
jones pointed out that "the boat lighter weight composite materials to reduce fuel consumption, or at the same speed or increase the carrying fuel increases." Other benefits include reduced maintenance and lower life cycle costs. Large ships can use the mixing process, such as metallic hull and composite superstructure.
The federal government will continue to promote reduced emissions
Insiders pointed out that they were concerned about the US EPA emission regulations that in the next decade will be even more stringent. Shipyard will continue to respond to customer needs saving fuel and using lightweight materials. Achieve environmentally friendly way and more than one reason, the importance of these two concepts shipbuilding enterprises will become competitive, long-term winner strict market regulations.
