SHIP REPAIR & CONVERSION: Review of 1994 Blohm + Voss performed one of the more innovative jobs of the year, win- ning an order to convert three Sea- Land ships. The contract entailed shortening each containership by three midship sec- tions — 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 Overseas Ohio had a head-on collision with an iceberg off of Alaska. The ship was carrying salt wa- ter as ballast at the time of the accident. Part of the $1 million repair work in- cluded 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. The two and a half year old Stena Concertina was in Norfolk Shipbuild- ing and Drydock Corp.'s (Norshipco) Titan drydock for blasting and coating; tailshaft and rudder clearance inspec- tions; valve, pump and generator re- pairs; and other planned maintenance and inspections. The vessel is a techno- logically advanced double-hull oil tanker from Mitsui O.S.K. Lines. 26D Maritime Reporter/Engineering News
