Robert Allan-Designed Hydrographic Survey Vessel Delivered By Allied Shipbuilders

Allied Shipbuilders Ltd. of North Vancouver, B.C., Canada, recently delivered the hydrographic survey vessel R.B. Young to the Canadian Department of Fisheries and Oceans, following a successful and extensive series of trials.

The vessel was built to a design by Robert Allan Ltd., Vancouver, originally prepared in 1984, and later updated prior to the awarding of a construction contract in 1988.

The R.B. Young will be based at the Institute of Ocean Sciences, Sidney, B.C., and will conduct coastal hydrographic survey work throughout the coastal waters of British Columbia. She is equipped with the very latest in scientific equipment for the performance of this work, and was designed and equipped so that upgrading and modernizing of electronic data recording and analytical equipment could be readily accomplished.

The vessel is of all-welded steel construction, with an aluminum wheelhouse, all constructed in accordance with the rules and under survey of the American Bureau of Shipping. The hull is of simple, double chine form, with a fine entry, full stern, and relatively full midsection.

A full height forecastle extends nearly 60 percent of the length of the vessel, leaving an open aft deck for a variety of equipment, depending upon the nature of work to be performed. Possible configurations include either two 8-meter survey launches, in davits, or hydrographic winches and stern gantry.

Vessel propulsion is by twin CP propellers, each driven by a high- speed marine diesel engine through a reduction gearbox. Installed machinery includes the following: main engines, Cat Model 3406, each rated 322 bhp at 1,800 rpm; gearbox, Hundested Model CPG 32, 4:1 reduction ratio; and CP propellers, Hundested, four-blade, 1,300-mm diameter.

Electrical power is provided by two 1,200-rpm Cat 3306 diesel generators, each supplying 95 kw of power at 240/3/60. Power stabilization is provided on all circuits supplying scientific systems.

The R.B. Young has accommodations for 11 persons—six ship's crew and five scientific mission staff.
