ASNE Day (continued) which was designed to identify and qualify those companies and private shipyards technically capable of managing combat systems work and conducting combat system testing.

The MOR program has had a lim- ited effect to date because the role of the MOR company is nebulous and subservient to the prime con- tractor. The Navy is represented in a private shipyard by the supervisor of shipbuilding, conversion and re- pair. As he talks only to the prime contractor, the Navy has until now no effective means to establish a proper MOR role.

Standard Item 009-67 is the solu- tion to this dilemma. Standard items establish uniform methods for requirements of ship repair and be- come part of the contract when they are invoked in the ship repair work package. This standard item de- scribes to the Navy planner how to estimate the size of the MOR team appropriate in the work package, a feature that will insure that combat system bids are tailored to a specific availability.

Naval Auxiliary Ship Designs," by

Alfred D. Issacson and John J.

Kron Jr.

The design of Navy auxiliary ships can benefit from the applica- tion of modern commercial tanker pumping systems practices. Navy auxiliaries that are outfitted for un- derway replenishment traditionally have at least one pumproom, and the designs are based upon a con- ventional pumproom-type cargo system with horizontal or vertical centrifuge cargo pumps. Each cargo tank has a dedicated suction line leading to the cargo pumps. In con- trast, the latest commercial product tankers, especially lighters, that most closely resemble Navy auxil- iaries in the manner in which they carry liquid cargoes, have been built with in-tank deepwell or submersi- ble cargo pumps, thereby eliminat- ing the pumproom. The application of this type of pumping system reduces the size of the ship consid- erably, thereby resulting in reduc- tion of required propulsive power and fuel consumption as well as a dramatic reduction in construction cost.

The paper discusses the three most common pumping system de- signs, with variations of each, and illustrates the differences in the sys- tems and their effect on the design of an auxiliary ship. 16
