SHIP REPAIR & CONVERSION: Review of 1994

Blohm + Voss performed one of the more innovative jobs of the year, winning an order to convert three Sea- Land ships.

The contract entailed shortening each containership by three midship sections from 950 ft. (289.5 m) to 856 ft. (261 m) — and giving each a new bow structure to improve streamlining. The Hamburg Shipbuilding Research Institute (HSVA) was involved in the hydrodynamic calculations and in the planning of the experimental work. The two and a half year old Stena Concertina was in Norfolk Shipbuilding and Drydock Corp.'s (Norshipco) Titan drydock for blasting and coating; tailshaft and rudder clearance inspections; valve, pump and generator repairs; and other planned maintenance and inspections. The vessel is a technologically advanced double-hull oil tanker from Mitsui O.S.K. Lines.

The Overseas Ohio had a head-on collision with an iceberg off of Alaska. The ship was carrying salt water as ballast at the time of the accident. Part of the $1 million repair work included replacement of the rudder bearings, for which Orkot was chosen.

Before & After: The transport vessel Super Se vant 1 (pictured above) underwent a conversh at Rotterdam's YVCBoln es Dockyard^ becomii the D.P. Fall Pipe stonedumping vessel Tidewc Rollingstone.
