Abstract:In recent years, there were many marine accidents happened at patrol-boat of Coast Guard. Among the various accidents, the event of fouled propeller happen most frequently. The statistics of accidents reveals that the fouled propeller possessed 75% of patrol-boat accidents. These accidents not only degrade the capability of patrolling but also waste a large amount of government budget. In order to reduce the accident of fouled propeller, this study investigate the major reasons to cause the fouled propeller for patrol-boat and fishing boat in Keelung costal area. To improve human careless mistake, the training navigator of patrol-boat by STCW (International Convention on Standards of Training,Certification and Watchkeeping for Seafarers) and ISM (International Safety Management) Code are required. For the construction propeller problem, this study proposes install propeller guard refer to literatures. Also, some interview with the propeller’s experts collecting their opinions to lay out a feasible way. Our research show that the best way is to install a protect guide ring in bottom of boat to prevent from fouled propeller. But the installation of propeller guard ring may reduce the vessel speed. Three possible ways to overcome the problem those are to amend the exterior of propeller ring, to adjust the propeller’s pitch of screw or to reduce propeller weight. The result of this study is to reduce the rate of occurrence for propeller fouled of small boats and to reduce the maintenance expense.
