A cost model is proposed for ships taking refuge from stormy weather such as typhoon. The model can evaluate the total costs clue to refuge at the berth inside harbour or at the anchorage outside harbour, respectively. The cost model is formulated as a function of Gross Tonnage of a ship and her departure delayed time clue to refuge. Main results by applying this model to three typical typhoans at Kobe Port during 1982 are as follows; (1) The cost increases in proportion to both Gross Tonnage of the ship and her delayed time for departure. (2) To take refuge at the berth inside harbour can make reduce ship's delayed time for departure by one-half compared with the case of taking refuge at the anchorage outside harbour. (3) As this results, it is much effective for cost reduction to take refuge at the berth inside harbour. (4) Based on this cost analysis, it is made clear that the proposed model can be applied for planning the effective size of ships and location of their berths for refuge from stormy weather.
