Seawater Heater Repair

Customer: Bumi Armada

Location: Offshore North Sea


Due to incorrect commissioning, the client’s seawater heater had a tube failure and required an urgent repair.


  • Bent and buckled tubes were difficult to remove, but the team’s experience meant that they were able to offer the client a solution that saw a complete strip down of the unit, removal of the tubes, installation of thicker wall tubes and upgrading of strength to the welds to give overall superior mechanical strength. 
  • The unit was then fully rebuilt, tested and returned to the client within the tight deadline.


  • Superior functioning unit
  • Delivered within three week tight turnaround.
