Sea Fury | Inshore Work Boat (Arctic 28)

The Sea Fury

The Sea Fury, an Arctic 28 inshore workboat, is compact yet powerful, perfectly suited for operations in confined or shallow waters. Its size and agility enable access to locations that larger vessels cannot reach, without compromising on capability. Sea Fury is ideal for inshore inspections, light intervention tasks, and support operations where precision and accessibility are essential. Despite its smaller footprint, it maintains the high standards of performance and safety that define our fleet.

The MV Equinox (Catamaran Nearshore Work Boat) was utilised as part of the Safe Caledonia reactivation and Special Periodic Survey (SPS) for client Prosafe.

All operations were executed in a safe, efficient, and highly professional manner. The RockSalt team played a key role not only in the successful execution of the work but also in the detailed planning, particularly for the cofferdam campaign. Their expertise and collaborative approach were instrumental in the safe and timely completion of this critical aspect of the project.   Neil Mackay, Technical Superintendent – Prosafe
