Twin Marine Heavylift AS (TMHL) is designing the Twin Marine Lifter system for
installing and removing platforms. Each of the two heavy lifters has 4 rectangular
buoyancy elements at one side, helping to lift the platform (on site) and place it on
the bigger transport vessel. The buoyancy tanks are a challenge when assessing both
resistance and course stability. DNV was called to assess the viscous resistance in
calm water, the forces on the buoyancy tanks and course stability.
