DCV vessel is capable of executing complex infrastructure and pipeline projects in ultra deep water, while offering sufficient lifting capacity to install platforms in relatively shallow water. These vessels are capable of operating in waters beyond 3,000 meters. They used for the installation of foundations, moorings, SPARs, TLPs, and integrated topsides, as well as pipelines and flowlines.
As a rule, deepwater construction vessels are outfitted with DP2 or DP3 technology for operations in very harsh environments. DCV are equipped with powerful offshore cranes and ROV work class systems.
On biggest DCVs the living quarters can accommodate up to 500 persons in single and double cabins or even up to 700 (like on DCV “Thialf”, Heerema).
