Propulsion pod pioneers ABB have won an order worth around US$25-million to supply its marine propulsion system, Azipod, and complete electric power plants for two new rescue and salvage icebreakers that are under construction at Nordic Yards GmbH in Germany.

The original idea for the Azipod (Azimuthing Podded Drive) system was conceived a couple of decades ago in response to the Finnish Maritime Administration’s quest for ways to improve its icebreaker operations. Icebreakers must be capable of manoeuvring in such a way that they can break out of an ice channel in any direction in order to assist merchant ships using that channel. Investigations showed that a propulsion motor which could direct the thrust in any direction would be the ideal solution to this problem. The Azipod drive system that was subsequently developed provided the answer with its podded electric propulsion unit, freely steerable through 360 degr... [More]
Polar King, constructed in Vigo on Spain’s Atlantic coast by century-old shipyard Constr. Nav. Paulino Freire S.A. recently entered service for Norwegian owners GC Rieber Shipping of Bergen. This week this hi-tech ship was already setting about the work she was built for; offshore rig and multi-purpose platform support services, as well as research (with ROV operating capability) in the North Sea hydrocarbon fields.
PropulsionThe DP equipped Polar King is fitted with a diesel-electric propulsion system powered by 6 x MAN 9L21/331 main generator diesel engines that each produce 1,980 kW at 900 rpm, while for manoeuvring purposes there are a pair of TT 2400 DP CP tunnel thrusters by Rolls-Royce Marine AS – Propulsion Ulsteinvik.
