In the mid 90’s 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 which 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 environment 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 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 allows to operate at different drafts 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 draft afloat. In third operating mode, the unit acts as a gravity based structure. Read more
