Home' Work Boat World : November 2009 Contents Rolls-Royce, the global power systems company, recently
announced that it had won a £7.5 million (US$14.45m) order for
the supply of podded propulsion equipment and stabilising fins
for the latest French Navy Mistral class amphibious assault ship.
This latest order follows earlier contracts to supply podded
propulsors and stabilisers on the first two ships in the class
-- 'Mistral' and 'Tonnerre' -- which entered service in 2006 and
2007 respectively. The third vessel, to be built by STX Europe, is
expected to enter service in 2012.
Rolls-Royce President, Naval, Andy Marsh said: "The contract
recognises our ability to deliver a wide range of propulsion and
motion control equipment and underlines our important
relationship with the French Navy. We are proud to play a part in
the delivery of the Mistral class."
Rolls-Royce is a leading supplier of marine systems and has
invested in excess of £5 billion (US$9.63bn) in developing the
overall marine product range over the past decade. The company
supplies 70 navies with products ranging from gas turbines and
diesel engines, to propulsion, motion control and electrical
systems, and has a growing network of marine service facilities in
The Mermaid Pod propulsor is a highly optimised propulsor and
steering device incorporating two electric motors housed in two
steel pods, mounted on the hull of the ship. The pod acts as a
rudder to steer the ship and the motor drives a propeller.
Converteam will supply the electric propulsion motors and
The stabilising fins are retractable and can be deployed from
their housing in the ship's hull to stabilise the vessel when sailing
through rough seas. Once deployed, stabilisers pivot to counteract
the roll of the sea to lift the vessel in a similar concept to that of an
aircraft's wing. Stabilisers perform an essential role in steadying a
ship during military operations such as the use of weaponry,
refuelling or during the take off and landing of aircraft.
The podded propulsors will be manufactured in the Rolls-Royce
facility in Kristinehamn, Sweden and the company's Dunfermline
facility in Scotland will produce the stabilisers. Final assembly and
tests of the pod propulsors will take place in Converteam's Rotating
Machines factory in Nancy, France.

Built in Malaysia, the Voith Water
Tractor (VWT) 'Ansar 20' has recently
entered service in Saudi Arabia. The VWT
is primarily used for assisting oil tankers
during loading and also serves as a
universal work boat for harbour towage,
escorting services and tug operations.
(See Work Boat World, August, 2009, 40).
The VWT is fitted with two Voith
Schneider 26GII/165 AE 45 propellers, each
driven by a 1,350kW diesel unit. The vessel
was designed by the Canadian naval
architect firm Robert Allan. NGV Tech in
Malaysia built 'Ansar 20' on behalf of Bakri
Navigation, Saudi Arabia.
The Voith Water Tractor is 29.7 metres
long, 11.5 metres wide and has a maximum
displacement of 150 tonnes. The main
winch in the stern of the ship features a
300-metre long special towline (UHMWPE).
The universal workboat has a bollard pull
of 35 tonnes and is capable of a maximum
speed of 13 knots.
