摘　　要：某海洋调查船要在原线型上增添一球鼻艏。从安装维修横隧道型艏推装置,降低船阻力和确保艏部流线光顺流畅不产生气泡等方面推荐采用大伸出上翘型球鼻艏。经船模水池试验验证,该鼻达到了预期效果。现此方案已赋于实施。An ocean survey ship needs a bulbous bow. The large-protruded upward-bending bulbous bow is recommended after studying various related aspects such as the arrangement of ducted bow thruster, reducing of ship resistance, keeping bow lines fair and smooth, and prevention against air-bulbs. This bulbous bow is proved effective by model basin test and is finally selected for the ship.
