Concept characteristics and economics Unlike for shipping, design performance for offshore units is rarely expressed in just volumetric or mass payload. It is a complex system of modular functionalities, mission specific equipment and supporting systems. The addition of LNG in cargo vessel types will usually result in loss of payload, or an increase in the unit’s main dimensions, i.e. footprint. However, for offshore vessels the total footprint might be governed by boundary conditions other than mass or volume payload; meaning that an increase in the total footprint due to LNG is not necessarily the case.
