Dual-fuel containership conversion
Under the contract, C-LNG will supply three 1350cbm type C LNG fuel tanks with in-tank pumps and tank gauging system, low-pressure vaporiser and buffer tank, glycol-water system, and N2 system for the conversion on board the Matson Navigation-owned Daniel K. Inouye.
TMC has been contracted by C-LNG Solutions to deliver the boil-off gas compressors for the FGSS. These can be used both dual-fuel vessels, for example LNG in combination with bunker oil, and single-fuel LNG vessels.
On board a vessel that uses LNG as fuel, heat from the surroundings increases the temperature inside the cooled down LNG fuel tanks, causing liquid to evaporate. The gas generated from this is known as boil-off gas. The system captures the boil-off gas from the LNG fuel tanks onboard, compresses it with a TMC compressor and injects it into the main engine as fuel.
“By compressing the boil-off gas to the required pressure in order to supply it as fuel directly into the ship’s engine, you have an optimal system with regards to energy efficiency,” said Hans Petter Tanum, TMC’s director of sales and business development.
“Utilising boil-off gas as a valuable resource is a clever way of reducing the vessel’s fuel costs quite significantly, with the added benefit of lowering harmful emissions to air too,” he added.
