Small offshore wind farm service vessels (WFSVs), which are designed for delivering minor maintenance tasks, will be used more frequently in the future operation and maintenance of offshore wind farms. However, small WFSVs usually have insufficient seakeeping capability. Upon arriving at site, they will meet difficulty in realising the safe transfer of crew and parts between offshore wind turbines (OWTs) and WFSVs. Some methods are already developed for addressing this issue, but none of them is ideal in practical application. Therefore, a feasibility research is conducted in this paper in order to develop a new measure for stabilising small WFSVs based on the static stability theory of ships. From the experimental testing results, it is surprisingly found that it is difficult to stabilise the twin-hull WFSVs in waves by using the proposed method as the static stability theory fails to consider the overturning moment that is created by the ballast mass block when it is in flow, except that the ballast mass block has little volume or it is put down to a very deep position where waves cannot reach. However, this is not realistic.
