Revolutionary sterngear system allows bearing replacement at sea: no dry docking required! A boon for shipbuilders and shipowners alike, this new Glacier-Herbert* system of withdrawable sterngear reduces bearing inspection and replace- ment time to a matter of hours. It also reduces the need for replacement: Because this system provides the means for a more accurate alignment of the bearing with the shaft, and offers improved lubrica- tion and cooling methods, it serves to extend bearing service life well beyond that expected from more conventional systems. The new Glacier-Herbert system allows the stern bearing and seals to be completely serviced from inboard while the ship is afloat at normal trim and at any draft. This eliminates the need for dry- docking for bearing service—a great time and cost advantage, particularly for tankers in the VLCC classes for which world ports offer only limited drydocking facilities. The system can be sized to fit within any vessel, and is compatible with all types of propellers and seals. * Developed by the Glacier Metal Company Ltd., and Mr. C. W. Herbert, Consulting Engineer. Proved in Service G-H withdrawable sterngear systems have been at sea in several vessels since 1970. In every case, sterngear performance has been exemplary: the function and maintenance advantages designed into the system have proved out as actual cost and time savings to the vessels' owners. As a result of this verified reliability, contracts have been signed to install the system in several more large tankers now under construction. Bethlehem is U.S. licensee Bethlehem Steel Corporation has entered into an agreement with Glacier Metal Company Ltd., holder of the system patent, to manufacture, in- stall, and maintain Glacier-Herbert withdrawable sterngear in the United States. With design work supplied by Glacier Metal, Bethlehem will build the systems, and then oversee their installation any- where in the United States. Construction and main- tenance work will be performed by our several repair yards on the East, Gulf, and West Coasts of this country. SEE IT IN HOBOKEN You are cordially invited to inspect a complete assembly of the Glacier- Herbert withdrawable sterngear system. Manufactured for installation later this year, the assembly will be on display from May 13 through May 17, 1974 at Bethlehem's Hoboken shipyard, 1301 Hudson St., Hoboken, N.J. For details, please call Gus Jonsson at the yard: (201) 659-2070, extension 240. BETHLEHEM STEEL Shipbuilding May 1, 1974 5
