There is a lot of concern and worry about the TRIWV, however in practice this need not be the case. It has been brought in for your safety and the safety of others. If you do have something seriously wrong with your ship then it is better that it is known and sorted.
The TRIWV comes in two parts: a safety survey of the ship ie equipment, bulkheads, fire extingures, etc and an out of water hull survey i.e. thickness of hull.
While out of the water it would be pointless not to have bottom cleaned which is needed anyway for hull inspection, anodes replace, bottom painted and anti-fouled if necessary.
A ship in the Netherlands must certified, the requirements are, for example:
  • Proof of ownership (English registry – SSR No.)
  • Fixed address in the Netherlands (a shipyard or shipbroker could suffice)
  • A hull report, not older than 2 years by a Dutch expert. The report must be viewable and preferably at the Dutch shipyard
  • Gas and Fire extinguisher inspection by again Dutch authority
  • Any verification work i.e Hydraulic crane or steering by and accredited Dutch authority
Certification number must be put on hull with chisel or welded to the identified/certified ship.
Zone 3.4 EU
  • Hull inspection completed to a standard accepted by insurance surveyors
  • Forepeak bulkhead required (though engine room bulkhead is advisory)
  • Steering mechanisms/capabilities inspected to a standard accepted by insurance surveyors
  • Reliable propulsion system and engine room at adequate safety level; for example:
  • Rotating parts protected
  • Gas oil tank and pipes made of steel
  • Steel tube surrounded/covered or casing pipe
  • Minimum attainable speed of 10km/h on quiet water
  • The propulsion system and manoeuvrability should be suitable for the relevant sea area
  • The steering of the craft should have safety measures such as a means of identifying the rudder position, siren (horn), reliable motor control system
  • (if present) the gas installation must be inspected by Dutch Shipping inspector or equivalent
  • Anchor installation is in good condition (in many cases, an anchor with ca75” a 100kg anchor is sufficient)
  • 2 Marifoons (1 with ATIS), and a control certificate
  • Blue Board with flashing light
  • In the near future AIS (Automatic Identification System). A collision avoidance system that gives information all the ships in your area, their speed and courses and how to contact them (name, call sign, MMSI). This information is publicly broadcast on VHF radio which can be picked up either by other ships or by shore based receivers.
  • At least 3 fire extinguishers (certified)
  • 2 lifebuoys, 1 with line, 1 with light
  • Life-jackets for each person on board
  • Navigation lights, regular, and a separate (emergency) anchor light
  • Boats hook, connection drum, binoculars, searchlight, rescue board ie means of getting overboard person back on.
  • Police regulation relating to area of operation and, if necessary, inventory accordingly
Relax... this is what you would want if purchasing a ship.
All the above makes it far easier for selling, if needed, at a future date. We feel sure that you will be able to include the cost into the sale price. It will make you feel safer, and insurance companies will be insisting that the ship is certified.
