| Summary: | 碩士 === 國立臺灣海洋大學 === 商船學系所 === 98 === Coast Guard Administration is the maritime law-enforcement agency, which executes the patrolling mission of the territorial waters and the economic zone and saving projects under a harsh climate. The administration is equipped by large, medium and small patrol vessels. The vessels which are over 500 tonnages enable to be on duty overseas while the Beaufort wind scale is over 9. Those vessels assigned by the Council of Agriculture and the Bureau of Customs and the ones made itself undertake the duty of the maritime law enforcement.
The seakeeping of the vessels is related to their size and length. Obviously, the seakeeping of the large vessels is better than the small ones. Among the similar vessels, the difference of the seakeeping exists. The stability of the vessels is the main factor of the seakeeping. It depends on the roll amplitudes and the acceleration. The former has influences on the sailors’ exercise capacity, and the latter causes seasickness and the damage of the equipments and the construction. Therefore, if the seakeeping criterion of exercise casting boats, salvaging operation, towing operation, and fire-fighting operation can be established, it will make the rules for the sailors, procedures and equipments to follow. Furthermore, it makes sure of the safety of the vessels.
The purpose of the present study is to investigate the ability of searching and rescuing of the vessels, the stability of the vessels, the seakeeping and the roll amplitudes, and the seakeeping and the wave. According to the investigation, the researcher investigates the vessel composition, the stability, the seakeeping and the operations. The researcher will analyze the data and confer the possible problem by means of the questionnaires. The study will be presented for the reference of the execution of the vessels and the construction of the vessels. The conclusion of this study is to provide a method for the administration to develop the ability of searching and rescuing, evaluate the executing situation, establish the criterion of the seakeeping, develop the seakeeping, and build the statistics of the sea states. Therefore, it can help to keep the vessels, staffs, and the equipments safe.
