NAVAL ARCHITECTS & MARINE ENGINEERS 100 Iowa Street Sturgeon Bay, Wisconsin Halter Marine Delivers Second Halmar 110 Class Tug Halter Marine-built Joel Robin takes an offshore drilling rig in tow on one of its first assignments after delivery. The second in a new class of all-purpose, ocean, and harbor service tugs has been de-livered to Robin Marine Corporation of Har-vey, La., by its builder, Halter Marine Serv-ices, Inc. The tug- is the 3,600-hp 110-foot Joel Robin. The new Halmar 110 (designation of the class developed by Halter Marine engineers) tug is built to American Bureau of Shipping classification Maltese Cross A-l ocean towing service. It has a beam of 30 feet 6 inches, a depth of 16 feet 3 inches, and a draft of 14 feet 6 inches. The steel hull of the tug is divided into seven major compartments by six water-tight bulkheads. The hull form of the Joel Robin features a soft nose stem with a slightly flared bow to furnish dry performance. A double chine form with a third chine introduced aft of amidships provides an unusually good water flow to the propellers. The Joel Robin is powered by two Enter-prise Model DMG 38 turbo-charged, after-cooled and direct reversible engines furnishing 3,600 hp at 600 rpm. Stainless steel, four-blade, 10-foot diameter Coolidge propellers turn on 9% inch diameter ABS Grade 2 steel forged shafts with stainless steel liners riding on B. F. Goodrich Cutless rubber bearings through Reintjes WAV 1651 3:1 reduction gearing. The main propulsion units are con-trolled through Morse single-lever controls at five stations throughout the tug?three in the pilothouse and two aft on the boat deck. Steer-ing is by Sperry Cub electrohydraulic system powered by 15-hp motors. The new tug has a free-running speed of 13.5. knots and a bollard pull of 115,000 pounds. Fuel oil capacity, normal, is 70,000 gallons; maximum of 86,000 gallons. Potable water capacity is 5,000 gallons and wash water is 10,000 gallons. The engine room of the tug is fully auto-mated with monitoring stations in the engine room and bridge and with alarms in the galley and chief engineer's stateroom. The system, of solid-state design, was manufactured by Pan American Engineering of New Orleans. Auxiliary equipment aboard the ocean tug includes electric motor-driven bilge, fire and washdown pumps, fuel-oil transfer pumps, pot-able water pressure sets, wash water and sani-tary water pressure sets, two Quincy 350 ten-horsepower air compressors with six 114-gal-lon air receivers, and a Douglas watermaker, Model D-10, which uses waste hot water from the generator cooling system. Caterpillar D333 Series C diesel engines drive two 125-kw 460-volt, d-c, 3-phase paralleled generators. The deck equipment on the Joel Robin is massive and is designed and constructed for heavy-duty operation. The combination towing and anchor pulling machine is an Interconti-nental set with side-by-side double drums driven by a Caterpillar D330 diesel engine through a torque converter. The vessel is equipped with a 15-hp electric single wildcat anchor windlass with 1,000-pound anchor in a hull recess with 720 feet of 1 inch high-strength chain, a Halter Marine vertical and horizontal hydraulically actuated stern roller assembly; and a 20-hp electrical vertical cap-stan with a 24-inch barrel. The Halmar 110 tug is equipped with a great variety of navigational equipment including Sperry Mark 27 gyro compass; Sperry auto-pilot; Raytheon 1105 AM radio-telephone; Raytheon 1275 AM single sideband; Raytheon 40A VHF FM radio; Raytheon 358A auto-matic direction finder; Raytheon DE 726 fatho-meter; one Raytheon 2502 radar and one RCA CPM-10 radar. The first tug in the Halmar 110 class was built for CIT Corporation, which leased the boat to Dole for operation in Hawaii. The class is available in several arrangements and in horsepower ranges from 1,700 to 4,500. The tugs are used primarily for ocean towing, an-chor handling, and ship docking. Dillingham To Acguire Vetco Offshore Ind. Dillingham Corp., Honolulu, has announced it is negotiating to acquire Vetco Offshore In-dustries Inc., a maker of offshore drilling equipment, in a transaction that could involve $27-million of Dillingham stock. The proposed transaction would be subject to the approval of the directors of both com-panies and shareholders of Vetco, which is based in Ventura, Calif. Dillingham is a di-versified concern with interests in land de-velopment, various types of construction and other operations. In a separate development, George S. Wheaton, executive vice-president, was named chairman of Dillingham, a post that has been vacant. J. C. Walker, senior vice-president, was made vice-chairman, a newly created posi-tion. Lowell S. Dillingham continues as presi-dent and chief executive. June 1, 1969 29
