  • 최근 서해지역 영해기점도서인 격렬비열도 인근 해상에 중국어선 불법어업이 증가되고 있으며, 인천 평택 대산항의 입출항 선박의 주요 관문로에 위치하고 있어 국토 최서단에 위치한 격렬비열도등대 기능을 강화하여 통항선박의 안전항행 유도, 불법어선 감시, 영토지킴이, 기상악화 시 어민들의 수난 구호기지 역할 수행 및 해양 기상관측시설물 관리 등 다양한 기능을 수행하도록 기반을 마련하였다.

  • Using motions (Maruo) and wave reflection (the author), speed loss due to wind (van Berlekom) and ITTC standard spectrum, and various effects of weather(:such as weather intensity, ship type, ship size and draught) on ship speed performance at sea were investigated. Further, a comparison of the relative effects of weather and hull roughness on speed loss was also studied for a VLCC.

  • An improved approximate formula is presented for Series 60 forms, modifying the approximate formula, developed by the Author in 1983. The weather formula is based on interpretations of detailed calculations of speed loss, due to wind(van Berlekom), motions(Maruo), and wave reflection resistance(Kwon). Comparison is made between the result of the approximate formula and the one of detailed calculation. The result of the formula is also compared with some published full-scale data for speed loss.
