The IMT 958 multi-role emergency response and rescue vessel (ERRV), which was named in the Balenciaga Shipyard in Northern Spain, is the first of two F-class vessels in the group's £110m investment which has seen 8 other vessels delivered to the company over the last two years.

At 58 metres long, the Grampian Fortress features diesel electric propulsion via twin Azimuth Stern Drives. It is also equipped with daughter craft and fast rescue craft as well as being able to transfer and store limited deck cargo and provide offshore locations with fresh water and fuel if required.

The Grampian Fortress will be joined later in the year by the second F-Class ERRV, the Grampian Freedom.
