The MARVEL HERON achieves significant improvements in both LNG carrying capacity and fuel performance through the adoption of a more efficient hull structure and an innovative hybrid propulsion system. After completion scheduled in September, it will enter into service primarily transporting LNG for the Cameron LNG Project, in which Mitsui is a participating partner.
The vessel is the second LNG carrier of its type built by Mitsubishi Shipbuilding for Mitsui. It features an LOA of 297.5 m, a width of 48.94 m, a depth of 27.5 m, a draft of 11.4 m, and a deadweight capacity of approximately 79 000 t. In addition to this, the total holding capacity of the tanks is 177 000 m3.
According to the statement, the order for the MARVEL HERON was received through MI LNG Co., Ltd, a joint venture established by MHI and Imabari Shipbuilding Co., Ltd to design and market newbuild LNG carriers. Construction was carried out by Mitsubishi Heavy Industries Marine Structure Co., Ltd – a Nagasaki-based MHI Group company – and launching took place on 2 February 2019.
Both ships ordered by Mitsui for the Cameron LNG Project are named after migratory birds. Alongside the MARVEL HERON, its sister ship was christened the MARVEL CRANE at a ceremony held on 21 February this year. The MARVEL CRANE was handed over to Mitsui on 28 March and is now in service.
The new vessels feature apple-shaped tanks refined from MOSS-type spherical tanks. This innovative tank structure results in increased LNG carrying capacity while keeping the ship’s beam within the parameters of passage through the newly expanded Panama Canal. Ship propulsion is performed by ‘STaGE’ – a hybrid system combining a steam turbine and gas-fired engines. It consists of MHI’s proprietary high-efficiency reheat Ultra Steam Turbine (UST) for ships, a dual-fuel diesel engine that accommodates both gas and oil, and an electrically propelled engine. Effective use of the waste heat from the engines to drive the UST results in significantly enhanced plant efficiency, enabling efficient navigation at all speeds, high to low.
