Skarhar Tanker Design Patented U.S. Shipbuilding Corporation, Inc. (USSC) has been issued patent No. 5,398,630 for a "Simplified Midbody Section for Marine Ves- sels and Method and Apparatus for Construction." This patent is the baseline concept for the Skarhar tanker design currently being de- veloped by USSC's sister company, Shipbuilding Ventures, Inc. The patent has been designed to reduce labor hours during tanker construc- tion, by using the patented produc- tion approach of automatically weld- ing longitudinal girders to an inner and outer shell. U.S. Patent Issued On New Flexible Liner Approach A recently-issued U.S. patent de- scribes a new approach to design- ing and installing flexible liners inside oil tankers and barges. In- stead of using large bladders or curtains, the approach uses small liner segments installed in indi- vidual stiffener bays. The edges of each liner segment are secured in a water/oil-tight manner, using clamping bars bolted to the inboard edges of stiffeners and web frames. Hull inspection is achieved by unclamping the bars, and using small segments reduces the costs of manufacturing and in- stallation. Since the clamping bars are positioned away from the outer shell, a liner segment can be pushed a substantial distance inward, if a spill occurs, without requiring drag- ging or sliding of liner material across a steel surface. The lining was invented by Phil Ross, with the help of naval archi- tects Leonard Stanton and Tim Layne, as well as Patrick Kelly, environmental engineer and presi- dent of JFKM Research.
