Mitsubishi Shipbuilding, NYK Line score ClassNK AIP for Large LCO2 Carrier
Mitsubishi Shipbuilding, a part of Mitsubishi Heavy Industries (MHI) Group, and Nippon Yusen Kabushiki Kaisha (NYK Line) wee granted Approval in Principle (AiP) from ClassNK for joint development of CO2 transport technology for liquefied CO2 (LCO2) carriers.LCO2 carriers transport liquefied CO2 at low temperature and high pressure, which is contained in the cargo tank system. Since the design of cargo containment system depend on the condition of liquefied CO2 such as their temperature and pressure…
Gas Ships: Large LNG Carriers ABS Addresses Tech Concerns
As the LNG trade significantly increase over the next decade, transporting the fuel in ever larger, more sophisticated ships means particular attention must be paid to technical issues to ensure the present and long-term viability of the new generation of larger LNG carriers. Operators continue driving the demand for larger LNG ships to take advantage of the economies of scale. "By increasing the size of the standard LNG carrier from about 145,000 to 200,000 cu. m. and even larger, it is estimated that there could be a reduction in transportation costs by as much as 15 percent," said James Gaughan, ABS Senior Consultant, Energy Project Development Group. Another advantage with larger LNG ship designs is a reduction in the amount of cargo boiled off as a percentage of volume.
