Abstract: 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.

Key words: GNSS attitude determination, hull stability, anchoring state, evaluation
