Ship history

Toisa was the first to order a customised Deepwater Enabler (HX102 design) newbuild, at Hyundai Heavy Industries (HHI) in Korea. 

The vessel design has been developed for maximum efficiency and cost effectiveness featuring heavy lift capabilities with active heave compensation, two moon pools, and up to 50t/m2 deck strength in key areas. The design includes a number of key features that give maximum capability and flexibility. These features include an AHC offshore crane rated at 900 tonnes SWL (Safe Working Load) with a depth capability of 3,500 metres, and a 200-tonne SWL knuckleboom crane with a 2,000 metres depth capability.

Furthermore, the vessel can accommodate a 550-tonne flex lay tower over the main 8.4 by 8.4-metre moon pool, and two 2,500-tonne-capacity carousels below deck. There is an enclosed ROV hangar for deployment of two large work class deepwater ROVs to port and starboard sides or through a central moon pool. This moon pool is also arranged to allow the deployment of a deck mounted saturation diving bell. The vessel is delivered with all necessary interfaces to service both ROVs and the saturation dive system.

Full compliance with the SPS Code is a fundamental principle of the design, which includes arrangements to meet Comfort Class COMF-V(3), the highest working environment standard. 

The deck area is designed to give optimised clear space for the installation of project equipment such as pipelay spreads, and for the carriage and deployment of heavy offshore equipment.
