Bermuda-based vessel owner, Toisa Limited, has inked a deal with Qingdao Wuchuan Heavy Industry (QWHI) for the construction of two DP2 Multi-Purpose Offshore Construction & ROV Support Vessels (RSV’s), to be delivered in mid-2017.

There will a working deck area of 1,100m2 and a working moon-pool of 7.20 x 7.20 metres. With a minimum deck strength of 10t/m2 and specific areas strengthened to take 25t/m2 carriage and deployment of heavy equipment and special project related machinery is facilitated.
Operational safety on the 97.10 meters long RSVs will be enhanced with provision of an enclosed ROV hangar, designed to accommodate two large work class ROVs for over-side launch. All the necessary interfaces to service ROVs, as well as dedicated offices, control rooms, workshops and stores are included in the hangar design, producing an ergonomically arranged space for efficient operation of ROVs.
The new Toisa’s RSVs will be able to accommodate a total of 100 persons in cabins and public spaces.
