London -- Bureau Veritas has given approval in principle for the basic design of a 14 000- container capacity vessel to be powered by LNG. The design, using rigid polyurethane foam to insulate the tanks, was developed jointly by Korea's Daewoo Shipbuilding & Marine Engineering (DSME), liner major CMA-CGM and Bureau Veritas.
The benefit of running on LNG is reduced emissions: at minimum fuel and maximum gas mode, when around 10 percent of the fuel is oil, overall CO2 emissions are cut by about 23 percent and SOX by about 92 percent.
"The market will determine when these ships can be ordered and built, but this is a real milestone as for the first time we have a fully worked and approved design for a main line ultra-large containership running on LN," said Jean-Francois Segretain, deputy technical director, Bureau Veritas, in a press release.
Segretain said an in-depth HAZID analysis allowed the team to "say with confidence that there are no technical or safety barriers to introducing LNG as a fuel for long-haul large containerships."
The fuel cuts operating costs, and lowers air emissions.
The vessel's LNG tank will be a Daewoo patent ACT-IB Aluminium Cargo Tank with polyurethane foam panel type insulation.
The vessel can also run on HFO (heavy fuel oil) if required, increasing flexibility in the period before LNG bunkering is widely available, the statement said.
