Hull Monitoring System. Volume 1:Phase III. System Installation and Evaluation.

摘要

The report is on the design and development of a prototype Hull Monitoring System (HMS) for use on merchant vessels. The overall objective of the HMS was to increase ship safety and to improve ship performance by generating appropriate information and recommendations through a minicomputer controlling strategically located sensors,information display consoles,and an interactive command console. For increased ship safety,the HMS monitored primarily ship stability,hull strength,cargo lashing strength,and flooding conditions. For improved ship performance,the HMS provided information leading to the optimum trim and levels in the roll-stabilization tanks with minimum ballast and the assurance of hull structural integrity and intact cargo. The HMS operates in four main modes:Cargo,Cruise,Fuel,and Damage. The development program was conducted in three phases:Phase I,System Definition,beginning in May 1974;Phase II,System Design and Fabrication,beginning in June 1975;and Phase III,System Installation and Evaluation,beginning in October 1976. In Phase III,the HMS was installed on the SS American Aquarius, a United States Lines Incorporated Lancerclass containership,for performance evaluation. In general,the HMS performed as intended. Recommendations are included for improving the reliability of sensor and operator inputs. This final report concludes Phase III. Included as appendixes are compiled data from the voyages,the Operating and Maintenance Manual for the HMS,and computer program descriptions and listings.
