When purchased the vessel had 4 X 2,500 litre steel fuel tanks. Only the stern port side tank was usable for fuel. The forward starboard side tank was used as a fresh water tank.
The other two tanks were so badly rusted that they were no longer serviceable. All four tanks were removed after closer inspection revealed that there was significant rust damage to the tops of all four tanks.
Two new fully baffled and triple layered ‘flexible’ bladder tanks were specially designed and made to replace the steel tanks.
Two highly structurally designed bays were constructed using heavy gauge steel and structural deck mesh. Steel uprights were bolted to the main ribs of the boat then a slightly sloping floors was constructed and installed. A heavy duty steel top frame was then attached and then the bays were bolted back to the main ship timbers using steel braces.
All the internal area of each bay was lined with several layers of carpet and then the bladders together with the bund lining were positioned. The bladders were attached to the top frame to hold them in place. Each tank nominally holds 3,500 litres, although total volume is very difficult to determine precisely.
Both tanks are fitted with a filling point & two breather outlets on the top. On the sides at the lower (forward) end they are fitted with a sight glass, water drain valve, fuel take-off valve, and a fuel transfer valve.
Both tanks are directly connected to the new fuel management manifold.
