The safe carriage of liquefied natural gas by sea is dependent on the structural performance of both the cargo containment system and the ship's hull. While for ease of reference it is normal to differentiate between the ship and the cargo containment system, it is fundamental to recognise that the ship, as a composite unit, is the cargo transport and containment vessel. In recognising this it cart be appreciated that compatibility in terms of interaction of the cargo containment system with the ship's hull, both in a local and global sense, are important considerations.

A new generation of LNG carrier design utilising the Moss Rosenberg Independent Spherical Tank Type 'B' containment system was proposed by Mitsubishi. The ship was to be of 125000m3 capacity and have four cargo tanks of equal diameter instead of the five cargo tanks as previously fitted to ships of this capacity. As a result of research and development by Mitsubishi the containment system was also to incorporate certain features that were new or had been refined from those fitted on previous designs.
