Marine Surveys

  • Vessel’s On/off hire surveys. The purpose of these surveys is principally to determine the extent of damage, other than fair wear and tear, which may have occurred to the ship between the commencement and termination of charter. Whilst the determination of damage is the principle purpose of the on/off hire surveys, they also include, checking of documents and certificates, establishment of quantities of fuel and stores on board and the establishment of cleanliness of the cargo spaces.

  • Vessel’s Bunkers surveys. Bunkers Surveys are carried out for DELIVERY and RE-DELIVERY purposes and also for Loss Control in supervision of loading/discharging of petroleum products by tankers or barges.

  • Vessel’s Draught surveys. The draught survey is the "before and after" survey, which determines, by measurement, the vessel's displacement before and after loading or discharging. The difference between these two displacements is the weight of cargo loaded or discharged.

  • Watertightness Tests. Hose test or Ultrasonic watertightness analysis are performed according to instructions received in order to ensure that vessels' hatch covers are watertight.
