由于工程要求,往往需要把井架、套管、各种平台、海上脚手架、基础沉箱、挖泥船等工程构件及施工机具,从海上浮运到安装地点,浮运的方式通常采用直接拖曳法、驳船装载法及重件运输船等方式。在这几种方式中,直接拖曳法要求构件强度本身具有耐风压、耐波浪冲击的能力;驳船装载法需要配备起重设备,而重件运输船在运输构件尺度上又有所限制,所以为了克服上述各种方式的缺点,达到安全而经济地搬运海上浮运构件的目的,最近采用了潜浮驳运输方式。
Due to the engineering requirements, it is often necessary to float the derricks, casing pipes, various platforms, offshore scaffolding, foundation caissons, dredgers and other construction components and construction machinery from the sea to the installation site. Floating methods usually adopt the direct towing method, Barge loading method and heavy cargo carriers and other means. In these ways, the direct towing method requires that the component strength itself has the capability of resisting wind pressure and wave impact; the barge loading method needs to be equipped with lifting equipment, and the heavy-duty carrier has some restrictions on the size of the transport component In order to overcome the above shortcomings of various modes and achieve the purpose of safely and economically transporting offshore floating components, the submarine floating floating mode of transport has recently been adopted.
