pre-purchase dredging vessel codition Surveys

Our dredging Vessel inspection involves a thorough survey of as much of a vessel as is accessible. This detailed technical examination is usually followed by a written report which lists the extent and nature of the defects found.                                                                                                The report starts with the Introduction, Description of Dredging Vessel and its main particulars as extracted from various plans and documents on board and/or supplied by the vessels Master/Chief Engineer. The Pre-purchase Dredging Vessel inspection by the independent marine surveyors shows:

  1.  The bridge navigation and communication equipment’s used. The Item, Mark & Specifications and Remarks are written in a tabular form.
  2.  The condition of the vessel accommodation which consist of the quantity and condition of the cabins, crew mess room and recreation area, sanitary spaces, air conditioning system.
  3.  Details about the ship’s hull which includes the plates, draught marks, type of rudder and propeller and bow thruster.
  4.  State of the main deck areas which constitutes of the deck plating, railings, mast house structures, air vents and sounding pipes, pipe work and walkways, deck lighting, hatch access and watertight doors.

Dredging Vessel Pre-purchase Condition Survey

Some of the conclusions noted during dredging vessel pre-purchase condition survey were the following:

  1. Superstructure and decks were visually noted to be in satisfactory condition, with satisfactory coating condition and no visual evidence of temporary repairs. Evidence of upgradation work in progress was noted.
  2. During our inspection on deck it was noticed that steering compartment, bow thruster and spud hydraulic room had evidence of oil leak, we recommended to the chief engineer of the dredger to maintain it clean and dry at all times to avoid any potential accidental pollution hazards.
  3. The dredger equipment were noted to be in satisfactory condition. As reported by the Chief Engineer of the cutter dredger, periodic checks are carried out on the cutter and the submersible pumps every 12 hours. Checks are also carried out on the ladder wire and positioning anchor cables.
  4. The spare gears were stored in the workshop and was reportedly as per the company requirements. The inventory was maintained in soft copy.
  5. One deck travelling crane Dreggen of twenty five (25) tons, tested and found to be operational. The winches were noted to be in satisfactory condition.
  6. The are four (4) ballast tanks and reportedly inspected as per onboard inspection programme. The ballast tanks were not inspected as they were not ready for man entry.
