锚定状态下船体的GNSS测姿稳定性评估

Stability evaluation of ship hull in anchoring state based on GNSS attitude determination

利用锚定状态下船体进行勘探作业是目前海洋工程勘探常用的作业方式之一,针对目前关于锚定船体稳定性分析的应用研究相对较少的现状,本文利用GNSS测姿方法对锚定状态下船体的稳定性展开研究分析,研究了船体在不同海况下(二、三、四级)的平面位置、高程、横摇、纵摇和艏摇变化情况,并对船体的稳定性进行了较为全面的评估,在判断船体稳定性是否适合海洋工程勘探作业、是否可安装钻机设备等方面具有一定的实用价值。

At present, it is one of the common operation methods of offshore engineering exploration using the anchored hull to carry out exploration operation. Aiming at the current situation that the application research on the stability analysis of anchored hull is relatively less, this paper uses GNSS attitude determination method to study the stability of the ship under anchoring state, and studies the plane position and height of the hull in different sea conditions(Level 2, 3, 4). The stability of the hull is evaluated comprehensively, which has certain practical value in judging whether the stability of the hull is suitable for offshore engineering exploration and whether the drilling rig can be installed.
