Rolls-Royce is a global leader in ship design, marine propulsion, engineering, hydrodynamics and systems integration. It offers a broad spectrum of products and systems across the marine market.

Today more than 20,000 commercial and naval vessels worldwide use Rolls-Royce equipment, and the company also powers 400 ships in 30 navies.

Ship design, integrated system solutions and ship equipment

  • Concept design
  • Complete vessel designs and integrated equipment packages
  • Diesel engines
  • Gas engines
  • Gas turbines
  • Mechanical, electrical and hybrid propulsion systems
  • Integrated propulsion and manoeuvring
  • Fixed pitch and adjustable bolted propellers
  • CP propellers and shaftlines
  • Reduction gearboxes
  • Azimuth thrusters for main propulsion, manoeuvring or dynamic positioning
  • Tunnel thrusters
  • Rudders
  • Steering gear
  • Deck machinery
  • Electrical systems and switchboards
  • Control, automation and condition monitoring

  • Dynamic positioning


Rolls-Royce provide complete design, systems and equipment packages for many types of vessel, including ropax and roro vessels, offshore service vessels, fishing boats, coastguard vessels and ice-going ships. Concept design and integrated system solutions are offered for many others.

As shipowners increasingly turn to liquefied natural gas (LNG) as a fuel, Rolls-Royce designs, engineers and supplies complete systems ‘from the bunkering flange to the propeller thrust’ using proven equipment and experience from vessels in service. Ship designs optimised for LNG fuel can also be provided.


Rolls-Royce is a global leader in design and manufacture of marine propulsion systems. These range from individual items of equipment such as propellers, azimuth thrusters or engines, to complete integrated ship systems including controls and condition monitoring.


Medium speed diesels in the Bergen range for distillate and heavy fuel, with powers up to 8,000kW. These engines can be supplied as propulsion engines for mechanical drive, gensets for diesel electric propulsion or as marine auxiliaries for large vessels.

Gas engines using LNG as fuel, with unit powers up to approx 7,000kW. These gas engines use the proven Rolls-Royce lean burn combustion technology to provide high output with low fuel consumption and much reduced CO2, NOx and particulates emissions compared with liquid fuel engines. For mechanical drive or as gensets.

Rolls-Royce marine engines meet IMO NOx and Clean Design class requirements without additional off-engine exhaust treatment.

Gas turbines for propulsion or as part of a GT/diesel electric system. Marine aero-derivative turbines in unit powers up to 36MW.


  • Fixed pitch propellers up to 10m diameter
  • Adjustable bolted propellers
  • Controllable pitch propellers in nickel aluminium bronze or stainless steel for all applications including highest ice class


Single input single output marine reduction gears with wide choice of torques, ratios and shaft offsets. Many power take-off options.

Azimuth thrusters – 360 degree steerable, mechanical or electric drive

  • Conventional azimuth thrusters with pushing propellers, open water or nozzle, CP or FP propellers
  • Azipull thrusters with streamlined underwater unit and pulling propeller, CP or FP
  • Contaz with contrarotating propellers
  • Swing up and vertically retractable azimuth thrusters
  • Combined azimuth and tunnel thrusters
  • Tunnel thrusters with FP or CP propellers


Aluminium and stainless steel waterjets to suit high speed vessels, from workboats to large fast ferries to naval vessels. The full range of Rolls-Royce waterjets spans input powers from about 200kW to more than 40,000kW per jet unit.

Complete propulsion systems

Rolls-Royce designs, engineers and supplies complete propulsion systems with mechanical, diesel electric, gas electric or hybrid transmissions.

The company has recently expanded its power-electrical capability and provides complete ship electrical systems including switchboards and variable frequency propulsion drives.

Motion control

Rolls-Royce is a major manufacturer of steering and stabilisation systems for both commercial and naval vessels The range includes steering gear to suit ships of all sizes, with conventional or flap rudders, passive tank stabilising and anti-heel systems, and retractable or fixed fin stabilisers including stabilisation at rest.

Deck machinery

A full range of deck machinery is offered, based on modular construction so that tailormade solutions can be provided at an economic price. Systems can be supplied with low presssure or high pressure hydraulic drive or multi speed or frequency controlled drive. There are specialised winches for offshore vessels and fishing boats, and ship-to-ship replenishment at sea systems for naval forces.

Support and service

Rolls-Royce has a worldwide aftersales support and service organisation, with experienced service engineers and technicians at key locations based at service workshops. Since Rolls-Royce marine equipment has a very long service life, many older items of equipment can be upgraded during overhaul. The product range has grown by development and acquisition, and many legacy brands are supported, including: Aquamaster, Liaaen, Peilo Teknikk, Normo, Norwinch, Ulstein Propeller, and Hinze.
