/ Semi-Submersibles

In the mid 90s Huisman was involved in the design of the Pride Amethyst 2 class semi-submersible drilling rig. The semi-submersible has a unique vertical riser storage designed by Huisman. Four semi-submersible units were built according to the Huisman design, including Huisman built riser handling crane and offshore cranes. We continue to use our experience gained in designing complete drilling semi-submersibles.

Orion

The innovative Orion Class is a Semi-Submersible drilling unit suitable for different water depths, that can be outfitted with a mooring system, a thruster-assisted mooring system, or with full dynamic positioning. The moored Orion is specifically designed for harsh environments mid-water areas (e.g. the Norwegian Continental Shelf) and the Orion with dynamic positioning for harsh environments (e.g. the North Atlantic, GOM, Brazil, and West Africa).  

The design of the units focuses on efficiency, health, safety, and the environment. The units feature a flat main deck, a drill floor flush with the main deck, and a dual Multi Purpose Tower allowing offline activities. Safe and simple material handling is achieved by the flush main deck/drill floor, a cargo elevator, and a forklift corridor in the deck box.

JBF Arctic

The Huisman-designed Arctic S facilitates operations at different draughts resulting in three main operating modes. The unique design combines the advantages of a conventional semi-submersible, resulting in low motions in waves and a heavily strengthened ice-resistant unit when operating in ice at deep draught afloat. In the third operating mode, the unit acts as a gravity-based structure. Read more.
