Formatank Ltd recently refurbished two water storage tanks on board a pipe lay and heavy lift vessel. The onboard engineers had noted deterioration of the coating, and walls of their fresh water hydrophore tanks, and relayed the diagnosis to Formatank. Understanding the importance of dependable water supply on board an industrial vessel, and challenges with replacing the tanks, Formatank accommodated the refurbishment requirements in a short timescale.
The restricted access to the two 6.5m3 water storage tanks didn�t pose an issue for the skilled Formatank team. A complete internal tank wall cleaning process was carried out removing the rust and grime build up. Upon completion of the surface preparation a full tank wall inspection was carried out to determine the most suitable course of action. The Formatank 2-coat GRP liner was applied to the entire internal tank wall adopting hand-lay technique method, and using WRAS approved materials. The GRP liner effectively creates a new internal tank wall, suitable for drinking water storage and in this case guaranteed for 5 years.
Within 48 hours the water storage tanks were back to ship shape condition and providing the dependable clean water source once again to the three-hundred vessel crew.
