2 Areas for technical consideration by the Administration

  2.1 Prior to agreeing to an in-water survey, the Administration should ascertain that:

  • .1 the owner has requested the Administration or recognized organization (RO) to approve the in-water survey at least four weeks in advance of the intended date of the inspection. The owner's proposed schedule and the conditions for performing the in-water inspection should allow effective planning and execution of the survey;

  • .2 the master of the ship has confirmed in writing that the ship, to his best knowledge, has not sustained any grounding or contact damage since the previous bottom inspection and that nothing unusual has been observed to suspect that any part of the ship's bottom or protuberances has been otherwise damaged;

  • .3 the Administration or its RO has reviewed the ship survey records to confirm current satisfactory condition of hull and machinery. Decisions of acceptability should be based on the condition of the ship, the hull protection system and the procedures that will be followed for the performing of the underwater survey; and

  • .4 a shipowner who makes a request for an IWS has completed, at a previous dry-dock, or during its initial construction, a preliminary survey of the hull to the satisfaction of the Administration or its RO that documents and establishes the ship's future suitability for an IWS. The preliminary survey will evaluate the condition of the hull and note that appropriate preparations, markings, fittings and capability have been satisfactorily installed, affixed or completed so as to accomplish the IWS in accordance with the recommendations specified in these Guidelines.
