Alstom to Equip DP-Controlled Vessels
Allstom will install an integrated DP system from its acclaimed 'A' Series
in Cunard Line's Queen Mary ll, which will be the largest cruiseliner ever
built when it goes into service in 2003.
In contrast, the company has also secured an order to fit a compact DP stand
alone system from the same series into what will be one of the smallest DP
controlled vessels in the world - a 14.9 metre long multipurpose catamaran.
The vessel, owned by MIKA AS, is being built at the Ulvan Bät AS shipyard in
Dynamic positioning enables vessels to maintain station without anchoring,
avoiding the need to have contact with the seabed and minimising
environmental concerns about damage to the local eco-system. Cruise ships in
particular benefit from such systems as it gives them a greater choice of
locations for tendering. Thrusters are used to counteract the effects of
wind, current or wave action - increasing passenger comfort in all weather
The A series is a complete vessel control system which combines dynamic
positioning with a broad range of automation functions.
The 344 metre long QMll, which is being built at ALSTOM's Chantiers de
l'Atlantique shipyard in France, will be fitted with an ADP02 integrated
system, which can be operated from three points on the vessel. It offers
full joystick contol - manual and auto-heading - as well as conventional DP
functions including station keeping, anchor mode, auto pilot, transit, auto
speed with Doppler log and 'relaxed DP'. Relaxed DP offers the additional
benefit of considerable fuel savings and reduced wear and tear on power
generation and propulsion equipment.
QMll will also be equipped with an ALSTOM and Rolls Royce MermaidTM podded
propulsion system - the first four-pod installation to date. Each pod has a
rated power of 22mW and will provide a speed of nearly 30 knots with low
noise and vibration levels.
Paul English, Offshore Sales and Business Development Manager for ALSTOM's
Marine and Offshore activity, said: "The modular nature of the A series
means it is flexible enough to incorporate a wide range of features for all
types of vessel, regardless of whether it is a huge cruise liner or a 15
