Naval procurement has changed dra- matically in the last several years, and while the procurement of fewer, multi- task ships is the norm rather than the exception, there have been rumblings from many fronts of late that a new wave of naval construction is needed to achieve the defense objectives of the

United States well beyond 2000. There are a myriad of strategic, political and fiscal factors, which help to determine the level of naval shipbuilding at any given time, however it is reasonable to assume that the projection of U.S. influ- ence around the globe in a continuous and seamless manner will require a fleet well above the current 322-ship navy.

Current projects whetting builder's and supplier's appetite includes Auxil- iary Dry Cargo Ship program, also known as ADC(X). The ADC(X), with three ships included in the proposed FY

Naval ships, fleet oilers, commercial container- ships, tankers and dredges are successfully finding new ways to operate more efficiently at lower cost, by utilizing Tranter's unsurpassed plate-type heat exchanger technology. Schematics presented here illustrate typical ways they are doing it.

Superchanger® plate and frame heat exchangers are used in a wide variety of shipboard applica- tions—particularly for cooling main engine jacket water and cooling main engine lube oil with fresh water or seawater; cooling the ship's central fresh water; cooling electronic equipment; or recovering heat from condensate. They are far more efficient than tubular systems, and provide heat transfer coefficients from rwo to five times greater than those achieved by shell and tube units. They also require 10% to 50% less deck space and weigh up to one-sixth less.

Superchanger units can be equipped with tita- nium plates which offer the best resistance to corrosion and erosion when exposed to seawater.

Intermixing or cross-contamination of hot and cold liquids is virtually impossible. Low fouling rates reduce cleaning requirements for

Superchanger units, that are designed for easy maintenance. They can be cleaned-in-place by back flushing, or quickly disassembled by hand, cleaned and put back in operation.

Platecoil® prime surface heat exchangers offer optimum temperature control. A Platecoil bank- in-tank unit provides wide interspaces for effec- tively passing solids while efficiently heating seawater containing oil from spills.

Platecoil bayonet heaters provide a large amount of efficient primary heating surface in a single unit for maintaining desired temperatures in ^tranter

SUPERCHANGER

UNIT storage tanks. These heaters help promote con- vection currents for better heat transfer rates and tank temperature uniformity. Platecoil suction heaters provide immediate heating for pumping oil out of tanks.

Tranter plate-type heat exchangers can be sup- plied in full compliance with codes and specifi- cations as required by the ABS: the U.S. Coast

Guard; shock testing per MIL-S-901C; vibration testing per MIL-STD-167-1; and ASME U stamp per Sec. VIII Div. 1.

Craft to Liquid Engineering Corporation of Billings, Mont. Specifically designed to replace underwater valves, fittings and piping on dams throughout the U.S., the vessel is equipped with an I-beam lifting system incorporating a hydraulic cable winch, allowing divers to recover dam equipment down to 200 ft. (60.9 m). Twin

Mercruiser 5.7L gas engines coupled to

Mercruiser Brovo II drive legs and pushes the boat to speeds in excess of 50 mph.

Crowley Marine Services Sets

New Quality Standards

Crowley Marine Services has earned certification of more vessels under the

American Bureau of Shipping's (ABS) joint ISO/ISM quality and safety manage- ment program than any other tug and barge operator in the Americas.

NASSCO Sends Off

Third Sealift Ship

NASSCO delivered its third Sealift

New Con- struction ship, USNS

Dahl, to the

U.S. Navy. Named for Specialist Fourth

Class Larry G. Dahl, who received the

U.S. Army Medal of Honor for his heroic efforts during the Vietnam War, the vessel was the first to be delivered under NASS-

CO's single integrated trial concept. This process, which lowered the ship's delivery schedule by five weeks, provided a signifi- cant amount of savings for the Navy.

NORSHIPCO Sets New

Standards With Renovations

NORSHIPCO, a subsidiary of United

States Marine Repair (USMR) and the largest non-nuclear ship repair, moderniza- tion and conversion company recently cel- ebrated the revitalization and renovation of its Norfolk-based shipyard facilities.

The changes promise to transform the ship repair industry. The refurbishment project, which was implemented as a result of the company's "People Are

Important" philosophy, consisted of not only the shipyard, but its interior, parking lots and Administration Building as well.

Landscaping work such as the addition of new trees, shrubs and flowers contribute to the yard's new look, and the exteriors of the shop warehouses have been stripped, siding was replaced and trims painted.

The ceremony, which was held on July 19 included U.S. Senator Charles Robb.
