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:
- The bridge navigation and communication equipment’s used. The Item, Mark & Specifications and Remarks are written in a tabular form.
- 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.
- Details about the ship’s hull which includes the plates, draught marks, type of rudder and propeller and bow thruster.
- 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.
- Type and specifications of the blocks and running gear.
- The condition and type of dredging equipment which includes inspection of pumps, hydraulics, wires, pipes, sensors etc. as far as it is accessible.
- State of the cargo tanks, ballast tanks, chain lockers, deck store rooms.
- Safety and fire-fighting equipment’s. Checking the number and quality of lifeboats, life-saving appliances, life rafts (inflatable), life jackets, immersion suits, thermal protective aids, life-buoys, gas detection system and which fixed fire-fighting system is used.
- Information about the machinery. The general engine room layout, cylinder running hours and wear, crankshaft deflections. The make, type, total running hours of the main engine turbocharger, the auxiliary engines and alternators/generators, and of the main air compressors.
- Performance of the dredging vessel. The records of the vessels trips are checked by the attending inspectors to establish the performances and/or consumptions of the vessel.
Finally the independent marine surveyor concludes the report with a pointed unprejudiced view of the vessel assimilated from the inspection conducted.
Dredging Vessel Pre-purchase Condition Survey
Some of the conclusions noted during dredging vessel pre-purchase condition survey were the following:
- 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.
- 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.
- 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.
- The spare gears were stored in the workshop and was reportedly as per the company requirements. The inventory was maintained in soft copy.
- 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.
- 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.
- The marine surveyors suggested that a follow up vessel inspection be carried out in order to establish the exact condition of the vessel and / or any new outstanding conditions remain after the completion of the survey.
