SAWE-RP12D, RECOMMENDED PRACTICE: WEIGHT CONTROL TECHNICAL REQUIREMENTS FOR NAVAL SURFACE SHIPS (22-MAY-2002)

SAWE-RP12D, RECOMMENDED PRACTICE: WEIGHT CONTROL TECHNICAL REQUIREMENTS FOR NAVAL SURFACE SHIPS (22-MAY-2002)., Naval ships by nature require a rigorous and proactive approach to weight control. Their unique missions and operating environments make them markedly different from other more conventional ships. Their unique requirements for survivability, seakeeping, maneuverability, and the need to undergo significant overhauls and upgrades during their service life coupled with their high sensitivity to weight and KG makes them a special case for weight control. New or specialized hull forms may add further to the need for significant emphasis on weight control. This recommended practice provides weight control technical requirements for all phases of naval surface ship acquisition (i.e., preliminary design through detail design and construction) and service life and also describes different types of weight estimates, reports, and weight control procedures. The purpose of this document is to promote uniformity and standardization in weight control and weight reporting. This RP describes weight control measures and requirements that are applicable to military vessels which typically require more stringent emphasis on weight control due to the need for upgrades in systems and functions throughout the life of the ship. This RP may also be invoked in whole or in part for other vessels such as commercial ships or offshore platforms as deemed appropriate. The requirements in this practice apply (either in part or in total) only as specified in a contractual agreement (e.g., contract clause, purchase order, etc.). This standard defines weight control technical requirements and describes the various different types of weight estimates and reports that may be contractually required by a ship owner. The contract will specify requirements for deliverables commensurate with the weight control program for the ship in question including data to be submitted, frequency of submission, number of copies, and recipients. Although the frequency and level of fidelity of estimating and reporting may vary, the definition of weight control products is uniform.
