Coast Guard Study
Reveals Double Hulls
Will Raise Shipping Costs
The Coast Guard recently con- ducted a draft Regulatory Impact
Analysis (RIA) of the proposal it made to implement the requirement of double hulls in OPA 90. The study found that the costs of double hulls, double bottoms, double sides, and smaller tanks would cost the opera- tor more, causing a decrease in al- lowable profits.
The Coast Guard stated that by mandating this requirement it would increase the cost of transporting petroleum by about $350 million.
The increased transportation costs would result from higher construc- tion costs, increased maintenance and repair costs, and a reduction in the cargo capacity of the vessel.
The double hull requirement will affect small inland barge operators, coastal barge operators, and tanker operators not in the Alaska trade more than large barge operators since double hulled vessels are al- ready in generalized use.
The draft RIA is available from the Coast Guard at a cost of $25, payable to the U.S. Treasury. To obtain a copy, call Bruce Novak of the OPA 90 staff at (202)267-6189.
Korean Contract Awarded
To FBM Support Services
FBM Support Services Limited, a subsidiary of FBM Marine Holdings (UK) Limited of Cowes, Isle of Wight was recently awarded a $7 million contract for the supply of materials and technology transfer to Korea
Tacoma Marine Industries (KTMI) for the construction of bridge erec- tion boats for the Korean govern- ment.
KTMI, one of the largest ship- yards in Korea, has been manufac- turing these boats as sub contrac- tors to FBM since 1985. In 1988,
FBM appointed KTMI exclusive lic- ensee for bridge erection boat sales in Korea.
The bridge erection boat was first designed and built in 1977 and is now deployed by the British, United
States, Turkish, Greek and Korean
Armies. Over 1000 of these boats are now in service.
Vicmar's Advance Fuel
Saving Technology For
A new fuel saving system designed by Vicmar Engineering Ltd. was recently installed and tested on the starboard main engine of the M/V
Seaspan "Greg", a roll-on/roll-off rail and trailer ship powered by two D399
Caterpillar engines. The main en- gine was monitored for a period of about a month-and-a-half, prior to installing the system, in order to establish data for comparison. The turbo chargers, after coolers and air gallery were dismantled, examined and photographed at both the be- ginning and the end of the monitor- ing period.
The fuel saving system consists of an Engine New Washing System and Turbo-Nozzle Ring Modifica- tion and, when used as a combina- tion, is capable of saving up to 6 to 8 percent of engine fuel consumption.
The engine new washing system al- lows turbochargers, air coolers, air intake manifolds, scavenging ports, or intake/exhaust valves to be kept in "like new" condition during nor- mal operation and maintain engine performance parameters in the de- sign range. The turbo-nozzle ring modification improves engine manufacturer's performance param- eters by coordination of turbocharger and diesel-engine characteristics.
Upon completion of the test, ac- cording to the chief engineer of the
Seaspan "Greg", Vicmar Engineer- ing Ltd., and Microfuel Computer, a visual inspection showed a remark- able difference, with components appearing to be in an almost-like- new condition after washing.
