These are markets in which we already operate a number of modern vessels but where we recognise that the future needs of the offshore industry cannot be fully met from the existing, and aging, world fleet. This large, capable, flexible unit has the potential to be further customized to individual client requirements and will represent a significant enhanced addition to Toisa’s existing construction vessel fleet. This vessel can, and will, support a wide variety of subsea operations world‐wide. This order will provide the market with a DP3 vessel where full compliance with the SPS Code is a fundamental principle of the design and also includes arrangements to meet DNV’s COMFORT Class. The vessel has all the inherent flexibility in design of previous Toisa construction vessels ‐ and more so. The under‐deck configuration provides space allowing installation of 2 x 2500 Tonne capacity under‐deck carousels, and/or a range of alternative equipment to be installed – similarly, a large deck area of c. 2900m2 is optimised clear space for the installation of project equipment such as pipelay spreads and the carriage and deployment of heavy offshore equipment for installation. A fully integrated vessel management and control system of all key functions is fitted on the vessel and includes the optional provision for deployment of a deck mounted diving bell through a central moonpool. The now common requirement for subsea construction vessels to accommodate large numbers of contractors personnel has also been addressed in designing the ship to accommodate up to 250 persons ( depending on Charterers requirements). Sealion Shipping Ltd currently operates four existing Construction vessels within its varied modern fleet of twenty five offshore support vessels. In addition, Toisa has a further five offshore support vessels presently under construction, that will join the Sealion fleet during 2013 and 2014. Further newbuilding projects remain under consideration.
