SIM surveyors conduct condition surveys for the purpose of determining the condition of a vessel or equipment at the time of the survey. The extent or characteristics of the survey can vary considerably, depending on the requirements given. They will carry out a thorough examination and report on the condition of the vessel, probable cause and recommended repairs, and an estimate of the cost. They also include certificates, reports, documentation, being attached to the final report.
The purpose of SIM Draft Surveys is to determine the weight of cargo on board the vessel using the density of the water in which the vessel is floating; from this total they subtract the weight of the vessel's structure and other weights on board which are not cargo. The difference obtained is the cargo weight. This survey includes reading the vessel’s drafts, measuring the ballast water, fuel and diesel oil and other liquids on board, and calculating the final quantity by using the vessel’s approved dead-weight scales and tank tables, and other documents.
SIM On-Hire Surveys / Off-Hire Surveys are conducted to determine the extent of damage which may have occurred to the ship and her equipment between the commencement and termination of charter. This inspection also includes the checking of documents and certificates and the establishment of quantities of fuel and stores on board.
