The new equipment has been developed in close cooperation with the Swedish Maritime Administration, SSPA Sweden and Stena Line and was tested extensively onboard Stena Danica in a variety of harsh conditions.

It is designed to be lightweight for easy deployment. The framework of the dock is made of aluminium or fibre composites, while the pontoons are made of fibre reinforced plastic completely filled with closed cell foam. These pontoons are additionally fitted with fenders as well as optional lifelines. An additional net turns the dock into an efficient means of rescue.

The system works by pulling the floating dock alongside the mother vessel. A permanently connected forward painter, joined to an adjustable painter boom, provides a safe distance to the hull side.

The FRB is then easily and safely driven into the MSS docking system until the stem of the boat enters a cone in the fore end of the dock. A pair of locks, one on each side, fits into a recess in the pontoons. For enhanced security there is a secondary lock consisting of two flaps connected behind the transom.

With the FRB in position, the dock and the boat form one single, controllable unit with good stability and buoyancy. The MSS dock is then pulled towards the hull and is optionally connected to the mother ship by a vertical guide wire along the ship's hull, hence reducing the swinging motion even further. In the event of the FRB slamming into the ship's side, as can happen in extreme seas, the boat is protected by the dock.
