远东码头船靠船靠泊作业风险评估与操作措施

Risk Assessment and Operational Measures of Ship-Beside-Ship Berthing at Yuandong Dock

相对于船舶靠码头作业,二程船靠泊一程船的船靠船靠泊作业要额外考虑两船之间的靠球、靠泊角度、系缆条件、作业协调和吃水差等风险因素,作业风险更大。对此,从二程船对一程船的撞击力、靠球的选型与配置、二程船靠泊时机、靠泊角度、靠泊速度、拖船配置以及靠球弹性的应对等角度出发,对远东码头二程船靠泊一程船作业进行靠泊方案风险评估、实景模拟验证、模拟操纵训练和多次靠泊实践探索,并提出相应的操作措施。该操作措施较好地解决了二程船特殊条件下在远东码头11#泊位靠泊一程船外当的安全靠泊问题。

The additional factors, such as use of fender balls, control of berthing angle, mooring conditions, berthing operation coordination, draught difference between ships, making the ship-beside-ship berthing operation more difficult and risky than berthing alongside the wharf. The risk of operation when the second-vessel berthing beside the first-vessel at Yuandong Dock is assessed taking into account the striking force from first-vessel, fender balls selection, optimum berthing time, berthing angle, berthing velocity, tug selection, as well as the elasticity of fender balls. The operation is simulated according to the realistic scenario and appropriate operation procedure is proposed and verified through practical operations at Yuandong Dock. The proposed operation procedure has been used at berth No. 11 of Yuandong Dock successfully.
