Far East Levingston To Build $37-Million Rig For The Western Company Western Co. of North America, Fort Worth, Texas, announced it has ordered a $37-million deep- water jackup drilling rig for de- livery in July 1981, from Far East Levingston Shipbuilding Ltd., a member of the Keppel group of companies in Singapore. In addition to drilling operations, Western provides other services to domestic petroleum operators. R.B. Inserra Appointed VP-Engineering/Operations At Atlantic Diving Co. Russell B. Inserra, former proj- ect manager of Atlantic Diving Company, Inc. of Gloucester, Mass., has been appointed to the post of vice president, Engineer- ing and Operations, by William T. Jebb Jr., president of Atlantic Diving Company. Russell B. Inserra "Mr. Inserra has been project manager on some very tough jobs for us—a 5,500-foot polyethylene pipeline installation, an 18,000- foot 72-inch-diameter concrete- coated steel pipe installation, and the installation of a 21-ton stain- less-steel cofferdam in the active spent fuel pit of a nuclear power reactor," commented Mr. Jebb. "And, over the four years he's been with us, Atlantic Diving Company has become the largest underwater contracting firm on the East Coast." Mr. Inserra is a graduate of Columbia University with an en- gineering degree. He has devel- oped proprietary techniques for ultrasonic testing of concrete un- der water, and has worked as a project engineer and diver on nu- merous underwater sewer and gas pipeline projects, cathodic protec- tion installations, and pier re- habilitation projects. ASSOPO '80 Set For June 16-18 In Trondheim —Program Available An International Symposium on "Automation for Safety in Shipping and Offshore Petroleum Operations" (ASSOPO '80) is scheduled to be held in Trond- heim, Norway, June 16-18, 1980. The symposium was organized by the Norwegian Society for Automatic Control, jointly spon- sored by IFIP (International Fed- eration for Information Process- ing) and IF AC (International Federation of Automatic Control). It will present the state of the art and potential future develop- ments of automation as a tool for improving safety in shipping and offshore petroleum operations. About 75 papers from 10 coun- tries will be presented during the three-day meeting. Among topics to be covered are: Instrumentation; Control Systems; Monitoring and Alarm Systems; Navigation and Traffic Surveillance; Risk, Safety and Reliability; Man-Machine Sys- tems ; Simulators for Training; and Maintenance Systems. This symposium is a successor of five previously held Symposia on Automation of Maritime Op- erations. About 400 experts from nations active within this field are expected to attend. The Program Committee has representatives from England, Finland, Japan, the Netherlands, Norway, Poland, and the USA. Registration deadline is March 15, 1980. Registrations are ac- cepted, with an increased fee, until May 1980.

The savings we delivered 4 years ago are FOUR TIMES GREATER today! At today's high fuel costs these savings can be up to $1,000,000 per vessel,** making SCAMP® hull cleanings an essential part of your profit program. If your vessel has been in service six months or more contact us immediately This ad appeared in major marine publications in 1976. fuel savings upto*228,(X)0 demonstrated asa result of regular hull cleanings with SCAMP underwater hull cleaning services An EXXON Corporation study determined actual cash savings from regular hull cleanings with SCAMP"' equipment. At Constant 21 MDWT 50 MDWT 250 MDWT Speed of Diesel Steam Steam 11 Knots $31,000 $127,000. $144,000 12 Knots $33,000 $141,000 $161,000 13 Knots $35,000 $157,000 $188,000 14 Knots $38,000 $185,000 $228,000 The net savings represent total tuel savings Irom regular hull cleanings and delay costs based on 4 to 16 hour cleaning periods. For example, (or a VLCC. the savings amounted to 6 tons of fuel pe' day or $36,000 per round trip The following chart illustrates typical fuel savings of a 50 MDWT vessel operating at a reduced speed of 11 knots as an example. Increase of shaft horsepower and fuel consumption becSme necessary to hold speed at 11 knots due to loss of hull and propulsion plant efficiency as time elapses Since regrowth of foul- ing takes place after each cleaning, maximum net savings are realized from a regular SCAMP hull cleaning program. In the preceeding example, net savings (fuel savings less SCAMP hull cleaning costs) were $127,000. Optimum cleaning programs are, every round trip for long-haul VLCC's and every four months for smaller vessels commencing at the onset of fouling, about 10 to 12 months after dry dock. A SCAMP hull cleaning program returns fuel savings many times greater than the cost of the cleanings even when operating at reduced speeds. Since its introduction, over 1600 vessels have been cleaned by SCAMP units. Many ship operators bank on it. A hmned number oI copies of mis Exxo-.
