Refloating Scenarios of an Intact Stranded Tanker

Document Type : Original Article

Abstract

In most grounding casualties, rapid refloating is desirable to remove the ship from a place of danger, to reduce stress in the hull and to minimize the risk of pollution. Different grounding conditions have been attributed to a candidate double hull tanker in order to investigate the possible refloating scenarios of the intact-grounded vessel. The refloating operation may consist of lightening and/or internal weight transfer. The objective of this paper is to illustrate an efficient weight management technique that may help the shipmaster to attain a good refloating procedure. For this purpose, each situation is analyzed; stability and strength check are made in order to depict the safe action to be undertaken. The results are graphically represented to make them of practical use for the operator. It is recommended that the resulting graphs are prepared in the design stage as a kind of Risk Management Solution, which helps the shipmaster to take quick, right and at the same time cost-efficient decision
