The Explorer Lifter is the first asymmetric semi-submersible unit without bracing in the world, which according to CIMC, results in lower towing resistance and improves sailing speed from an average of about 8-9 knots, to more than 11.3 knots. De-ballasting operations are accomplished via a much quicker pneumatic system to suit heavy lifting operations. This system reduces ballasting times by 75%.
With a 3600 ton tandem lift capacity, and 18 meter weight height operational requirements, the Explorer Lifter can meet the requirements for most offshore lifting operations and be applicable to West Africa, Brazil, Mexico and Southern Area of UK North Sea.
