Extendable Draft Semisubmersible
Extendable Draft Semisubmersible (EDS) is a cost-effective, hybrid, ultra-deepwater, dry tree drilling semisubmersible. It can operate in waterdepth of 2,200 metres in the Santos Basin, offshore Southern Brazil.
EDS E-Semi wave basin model test in LabOceano.
EDS wave basin model test was successfully conducted in LabOceano in May 2012.
Classification societies, ABS and DNV, have acknowledged the feasibility and reliability of this concept for offshore Brazil ultra-deep waters.
