SEABED CONSTRUCTORMulti-Purpose Offshore Construction Vessel
A versatile Subsea Support and Construction Vessel, providing fully integrated subsea services worldwide
VESSEL SPECIFICATIONS
MAIN CHARACTERISTICSEXCELLENCE IN SUBSEA OPERATIONS
Owned and operated by Swire Seabed, the Seabed Constructor is fully equipped with heavy duty WROVs, a multiple AUV survey spread and is fully supported by dedicated on-shore engineering and survey teams. Acquired by Swire Pacific Offshore (SPO) in 2012, the focus of our business is now primarily on providing a highly flexible range of integrated services – IMR, subsea construction, subsea engineering and seabed survey. Being part of one of the largest companies in the offshore industry, with a network of over 20 offices, has enabled us to combine our cutting edge practical skills with the international support required to service our clients worldwide.
A strong culture of co-operation exists between the marine crew from SPO and the project crew from Swire Seabed, and they both work closely with our project management department which incorporates both marine and project related parts of the operation.
It is a well proven portfolio of integrated subsea and marine services that enables us to deliver safe and customised solutions to our clients globally.
