DP incident

Following a recent DP incident, which occurred when alongside a fixed installation, a contractor has issued the following safety notice. There was no damage or injury to either personnel or assets.

  • DP Operators must be aware of the blind areas which other ships or structures can present when operating on DGPS reference systems, particularly when using land based differential systems.
  • The effect of lit flares on DGPS signals (and other radio signals) needs to be assessed when considering operations close to flare booms.
  • All available reference systems should be made available and ready for immediate operation when operating close to other vessels or structures, particularly when DGPS reference systems are being used as the prime references.
  • Taut wires should be lowered to a position above the seabed clear of the highest obstructions and not less than 10m above the bottom.
