Replenishment-at-sea
» View the image gallery

Rolls-Royce supply a range of underway replenishment (UNREP) and refuelling at sea equipment. Semi-automated all-electric systems have been developed to complement conventional abeam and astern refuelling rigs.


Each of the four rigs on the RFA Fort class replenishment ships can transfer solids or liquids

For liquids and solids transfer (currently two tonne load) the dual capacity high performance rig transfers loads from a single station and can safely operate up to sea-state 6 and 7.

As the system is semi-automated, an individual at the control console operates all winches involved in the transfer from the supply ship.

Features and benefits

  • All-electric for low manning and low maintenance
  • Semi-automatic operation for improved safety
  • Capable of operating up to sea-state 7 (liquids)
  • In service with 12 navies

Moveable HighPoint (MHP)
The Rolls-Royce Moveable HighPoint gives vessels to ability to receive liquid or solid transfers and can be installed during build or retrofitted. They are manufactured to the required length to ensure the reception points are at the correct height relative to the distance from the deck edge.
