Work is continuing on the two-phase modernization scheme at Halifax Shipyards in

Nova Scotia. First new floating dock named Scotiadock (shown here) is now in operation. The oversized Panamax floating drydock will be inaugurated in late 1980. $C19.5-Million Modernization

Under Way At Halifax Shipyards

A two-phase, 19.5-million Ca- nadian dollar modernization pro- gram is being carried out by Hali- fax Industries Limited, Halifax,

Nova Scotia, at its ship repair facility, Halifax Shipyards.

William J. Riley, president and chief executive officer of Halifax

Industries Limited, says: "Given our very competitive cost levels and our strategic geographic lo- cation, we believe Halifax has a big future in North Atlantic ship repairing, and this modernization program will greatly increase the efficiency and technical standards we can offer customers."

Phase one of the moderniza- tion scheme, which cost $C7.5 million, has already been com- pleted. This phase entailed con- struction of the foundation for the yard's recently commissioned 185-meter by 25.2-meter (about 607 by 83 feet) floating dock,

Scotiadock, which has a lifting capacity of 16,000 tons. Also in- volved in phase one was the re- placement of older piling at Pier 6, and the total rebuilding of the machine shop wharf.

The water supply distribution system in the yard has been to- tally replaced with a new under- ground system that provides greater fire protection and pump- ing capabilities. Also replaced were the distribution systems for steam, air, oxygen, acetylene, and condensate. The new systems can supply 100 pounds pressure of steam or air to any location in the yard. Oxygen and acetylene are now stored centrally, and there is a new underground sup- ply system to all the yard's fa- cilities. Also underground is a new 25,000-volt electrical system.

Company and the Dillingham Mar- itime Group, of which Foss is a part.

Named to new positions are

Alfred J. Conway, from vice president-finance for the Western

Division of Dillingham Maritime to director-group administration and finance for Dillingham Mari- time Group; Gary Hoglufid, from manager-planning and control to vice president-finance and plan- ning for Foss; and Gary Low, from senior financial analyst to supervisor of planning and con- trol for Foss.

Mr. Conway has been with Dill- ingham since 1968, and in Seattle since 1974. He will transfer to

Dillingham's corporate headquar- ters in Hawaii later this summer.

Mr. Hoglund joined Foss in 1970.

Mullan Named General

Manager At Jet Blast

Division of Jet Blast Company, a wholly owned subsidiary of Ma- rine Equipment & Services Co. of

Hoboken, N.J. The announcement was made by Marine Equipment president Francis J. Dunlap.

Before joining Jet Blast early this year, Mr. Mullan was sales manager, Gulf Coast District, for

Norlin Corporation.

Jet Blast offers a wide range of high-pres.5ure water blasting and related services to the marine industry. Mr. Mullan will be lo- cated at the Jet Blast office at 1306 Raleigh Avenue, Norfolk,

Va. 23507.

SNAME Chesapeake Section

In total, 33,000 feet of piping was used to install the new systems.

New machinery purchased in- cluded a heavy-duty lathe with a 72-inch swing over the bed and capable of handling shafts to 40 feet. Also acquired as part of the first phase improvements were a metal-cutting saw, a jib crane, a heavy-duty spray washer, a tur- ret lathe, a bandsaw, a bake oven, pipe-threading machinery, and a drill press.

In addition to the yard's $C7.5- million first phase, $C6 million was spent on the purchase and commissioning of Scotiadock.

The next phase of the scheme, which will cost another $C6 mil- lion and involve the moderniza- tion of the yard's steel fabrica- tion facilities, is now going ahead.

New machinery for a plate prep- aration (shot blast and paint) line and a panel welding line will be purchased. Also in this phase will be the rebuilding of the yard's slipway, on which stern trawlers are to be built.

In addition to Scotiadock, Hali- fax Shipyards is to acquire in late 1981 the use of an over-sized "Panamax" floating dock capable of handling vessels of up to 116,- 000 dwt. This $C43.5-million fa- cility is to be bought jointly by the Canadian Federal Government and the Provincial Government of

Nova Scotia, and then leased to

Halifax Industries Limited.

The Chesapeake Section of The

Society of Naval Architects and

Marine Engineers met recently at

Walter Reed Army Hospital's Of- ficers' Club to hear a paper by

Richard A. Swanek and Alfred

L. Dinsenhacher, both of David

Taylor NSRDC, and Lt. Michael

F. Flessner of the U.S. Coast

Guard, on "Cargo Tank Overpres- surization and Procedures for

Vent System Evaluation and De- sign."

Because of the number of ac- cidents in tank vessel operations, more attention is now being given to the design and operating pro- cedures for tanks containing liq- uids that produce flammable and or toxic vapors, to ensure that the safety of the ship and its per- sonnel not be compromised.

The paper presented analytical methods for evaluating pressure buildup in marine cargo tanks so as to prevent overpressurization of these tanks. In particular, the paper addressed the loading and unloading of volatile and non- volatile liquid cargoes carried in bulk, and provided a method for evaluating overpressurization haz- ards during cargo transfer oper- ations.

The student paper presented by

Robert J. Kaslner, a midshipman at the U.S. Naval Academy, dis- cussed the harnessing of ocean wave energy through wave en- ergy focusing using a submerged lens-shaped structure. Midship- man Kastner recounted the ex- periment he conducted at the

Academy, which showed that a lens-shaped structure can cause wave height magnification of 1.5 times the incident value. 38 ZIDELL Maritime Reporter/Engineering News
