Conversion of Tow Tankers into a Storage Tank Barge

Abstract

Tow old forebodies cut off from the jumboizing tanker, joined together and converted into a crude oil storage tank barge for use by the Gulf Oil Co. in Nigeria. Cutting and joining work was performed in our floating dock, which is very narrow and short to accommodate above tankers and forebodies. Therefore, detailed work procedure, including combined ship and dock ballasting, was carefully studied so as not to inflict any damages upon ship's hull and dock construction. Each 43 m overhung bow of the forebodies are supported by the floater of 400 t buoyancy when docked for the joining, to assist the dock's lifting capacity and mitigate the bending moment occurred at the ship and dock construction.
