The new OESV, measuring 120 meters in length and 23 meters in beam, is designed
to excel in a wide range of offshore operations, offering the flexibility to work efficiently across
various tasks: it ensures the safe transportation of personnel to marine structures, supports
maintenance teams, and fulfills multiple functions, including wind CSOV operations, offshore construction,
subsea installations, inter-array cable laying and repair, dredging, and ROV inspection operations.
Additionally, it provides pipe transportation, diving support, and complete first class accommodation.
