Technical Report On Mooring For LNG Ships Released By MarAd The Maritime Administration has released a technical report on the feasibility of a new Single Point Mooring (SPM) concept de- signed for ships carrying liquefied natural gas (LNG) and other low- temperature cargoes. The study was carried out by Donaldson Associates, Rancho Palos Verdes, Calif., under con- tract to the Maritime Adminis- tration. Additional funding and technical support were provided by Pacific Marine Associates, a jointly held subsidiary of Pacific Lighting Corporation and Pacific Gas & Electric Company. The cryogenic SPM provides an unmanned, remote tanker moor- ing and transfer conduct which is operable in an unusually wide range of weather conditions. It does not have liquefaction, stor- age, or vaporization capability and is, therefore, used in conjunction with an onshore or offshore stor- age facility. The study concentrated on five key areas: (1) motion character- istics of the cargo transfer buoy; (2) design of the marine hose as- sembly; (3) design of a coaxial LNG/vapor swivel in the top of the buoy; (4) a self-sealing dis- connect, and (5) pressure drop and thermal analysis for a tri- axial pipeline concept. Positive results were obtained for each of the key areas investi- gated. The report concludes that subsequent technical effort can follow the normal design path for new marine systems, namely, test verification of the analytical results obtained. The final report is available from the National Technical In- formation Service, 5285 Port Roy- al Road, Springfield, Va. 22161, for $5.50. The order number is PB-283474/AS. New Diesel/Electric Supply Boats Featured In Halter Brochure An eight-page brochure, re- plete with color photos and de- scriptions of the many types of vessels built by Halter Marine, Inc., features a new type of HAL- MAR tug/supply vessel using diesel/electric propulsion. Halter Marine, Inc. is the world's largest builder of supply vessels for the offshore oil in- dustry. The company owns and operates 10 shipyards in the Southeastern United States, and builds a wide variety of vessels, including crewboats, tugs, utility boats, fishing vessels, and oceano- graphic research vessels.

MAULThe first vessel in the U.S. to apply the most unique bottom coating in the world/ SPC EM jfll \ V ij Ihi / t x -tflf \ 1 fifoS MAUI: dark area-Cathodic Protection Dielectric shield; green - first coat of SPC; blue - second coat of SPC. MAUI: ready for sea with 4 coats of SPC. Matson's new 720', 38,700 ton maximum displacement container vessel, MAUI, has been coated with SPC self-polishing copolymer by Maryland Shipbuilding and Drydock. Built by Bath Iron Works, MAUI went through fitting out period with only an anti-corrosive coating below the waterline. Prior to receiving 4 coats of SPC the only surface preparation required was a high pressure water wash. SPC self-polishing copolymer antifouling bottom paint is a revolutionary coating patented by International Paint Company. The unique chemical combination of biocide and vehicle allows the water turbulence to polish SPC's surface as the ship passes through the water. Not only does the hull remain clean but the progressive smoothing of the underwater hull results in significant operational savings. You too can expect to save at least 12% in fuel costs if you coat your vessels with SPC. You will also require fewer drydockings because the life of SPC is directly proportional to its thickness. Recoating with SPC is simpler than with conventional antifouling systems. A high pressure water wash, touch up of physically damaged areas with anti-corrosive, and the surface is ready for enough additional coats of SPC to last until next planned drydocking two, three or even four years away. Contact your nearest International Marine Coatings representative and challenge him to show how much SPC can save for you. International Marine Coatings International Paint Company, Inc.
