Destined for the Gulf of Mexico, the deep-water semi-submersible crane & accommodation vessel Explorer Lifter was delivered today by Yantai CIMC Raffles Offshore Ltd.

Designed, constructed and commissioned by CIMC Raffles. the Explorer Lifter is a new generation offshore tender unit classed by ABS integrating the functions of heavy-lifting, storage of cargo, and accommodation.

Rig particulars:

  • LOA: 137.5 meters
  • Beam: 81 meters
  • Draft: (base line to main deck) 39 meters
  • Maximum Variable load 7070 tones,
  • Accommodations: 618 people
  • Dynamic Positioning: DP3
  • Power Generation: 8 x 3860 KW main generators
  • Propulsion: 6 x 3800 KW full-revolving thrusters.
  • Crane: 2 x 1800 ton offshore mast crane

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.
