Supacat Multi-Purpose Vessel 24 (SMV24) is an offshore support vessel (OSV) built by Mustang Marine (Wales) for Supacat, who ordered the vessel in February 2013. The vessel was built at Mustang Marine’s Pembroke Dock facility in the UK and launched at Seawork International in June 2013. James Fisher Marine Services (JFMS) purchased the vessel from Supacat in April 2014.

SMV24 is designed to act as a multi-purpose platform to perform wind farm and offshore maintenance roles up to 150nm offshore.

SMV24 design and features

Designed by naval architecture firm Incat Crowther, SMV24 is built of marine grade aluminium with double bottom to survive damages. The boat has an overall length of 25.7m, beam of 8m, height above the waterline of 24.4m and draft of 1.5m.

SMV24 received a number of DnV (Det Norske Veritas) 1A1 class notations, including HSLC R1 Wind Farm Service 1, and carries a UK MCA SCV Code (MGN 280) Category 1 flag meeting individual flag requirements for Sweden, Norway, Denmark, Netherlands and Germany.

The vessel features an extensive and multi-functional deck space to hold equipment, including specialist diving equipment, remotely operated vehicle (ROV) equipment, operations and maintenance equipment, accommodation modules and ship to turbine (STT) oil change service.

It can handle 30t of cargo using its pillar-free cargo deck, which is flat from stern to stern and fitted with a set of container rails covering the full length of the vessel, allowing movement of container loads up to 10ft on the aft and up to 20ft on the forward deck. The rails also allow movement of a deck crane mounted on a base frame.

The crane is secured to its location by tie down points fitted throughout the deck. Removable hand rails are fitted throughout the deck, connecting the forward and aft boarding points to allow safe movement of personnel by providing access to the passenger cabin and accommodation spaces.

For improved visibility, the wheel house is located at the upper deck. Skylights are fitted allowing the operators to see the turbines during docking.
