French shipbuilder OCEA unveiled a new multirole offshore support vessel (OSV) at the Euronaval 2022 maritime exhibition in Paris.

Derived from the shipbuilder's 60 m Rigel (OSV 190)-class survey ship, which is in service with the Indonesian Navy, OSV 315 is designed for offshore oceanographic research and hydrographic survey missions as well as search-and-rescue and maritime security operations in coastal and offshore waters.

Speaking to Janes at Euronaval 2022, Philippe Neri, OCEA director of maritime safety and security, said that OSV 315 had been designed to meet evolving customer demand for a multirole support ship with increased autonomy, range, and endurance, compared with the 60 m Rigel class; with the capacity to carry a greater number of scientists onboard; and the ability to operate a wide range of unmanned systems.

Featuring an aluminium hull and superstructure, with an overall length of 95 m, a beam of 17 m, and a draft of 5 m, the ship is the largest yet to be offered by the company. It carries a crew complement of 75, with accommodation for an additional 35 personnel.

Propulsion is a combined diesel and electric arrangement that provides for a maximum speed of 16 kt at full load and a cruising speed of 12 kt. It has a range of 10,000 n miles at 12 kt and an endurance of 45 days.
