以下节录JOHN SCHOFIELD 先生所著的《Laytime and Demurrage》一书第五版之4.189段给你参考：“The question to be asked seems to be: could cargo of the type intended t be loaded or discharged be safely loaded or discharged without undue risk due to the weather conditions then prevailing at the place where the parties intended cargo operations to be carried out？ In answering this question it is irrelevant whether the vessel concerned is herself at the loading or discharging point. Clearly, if the vessel is in position then evidentially it is easier to establish, but if she is not in position and no similar cargo is being worked at the loading/discharging position then the question will have to be determined on a theoretical basis.”。
