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 is a self-propelled semi-submersible drilling unit. Depending on the design it can work in mid water or ultra-deep water and in moderate or harsh environments. All models can be outfitted with a mooring system and/or thrusters and have a drill floor, construction floor and drilling tower. Read more

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
