The refrigerated motor ship Polarstern was built in 1964 for Hamburg Süd at the Deutsche Werft ; It took seven months from laying the keel to delivery.
history
The Polarstern sailed from 1964 to 1970 for the Hamburg Süd shipping company . In 1970 she was sold to Friedrich Brante Ravenna KG and chartered back by Hamburg Süd for four years. In 1974 the Polarstern was sold to the London-based Fyffes Group Ltd. sold and renamed Darien . From 1981 the ship was operated under the name Chin Carrier for two years after it had previously been sold to the Greek shipping company Ichnusa Shipping Corporation in Piraeus . In 1983 it was sold to Helm Master Shipping Corporation Panama , renamed Khumbu , sold to Pakistan for demolition a year later and demolished in Gadani Beach .
description
The ship had a length of around 143 m, width of 18 m and was measured as a full-decker with 4970 GRT. The bridge and the engine room were arranged amidships. Four continuous decks resulted in 17 refrigerated holds with a height of 2.1 m, which were combined into 8 hold groups in separate cooling zones. With the nominal power of 11,400 HP, the ship ran at a banana draft of 22 kn.
The specialty of the Polarstern was the progressive automation . The machinery with the auxiliary systems was largely automated and the cargo cooling system was fully automated. The refrigerated ship was therefore considerably more expensive than normal liners , but could be operated with a crew reduced to 27-29 men. This reduced the running costs of the ship operation. Without automation, around 40–45 men would have been required for a reefer ship of this size at that time.
The slow-running MAN main engine and the necessary auxiliary systems were driven fully automatically and could be approached or operated remotely from the bridge via the engine telegraph or from the engine control room (MKR). After switching off the automatic, the machine could also be operated by hand. The power supply and the auxiliary systems were automated. The second auxiliary diesel provided in the priority circuit started when the power consumption increased and the generator it drives was automatically synchronized with the on-board network, switched on and the load evenly distributed over both generators. If power consumption fell and only one auxiliary diesel was required, the load was automatically reduced, the generator was switched off and the excess auxiliary diesel was switched off.
