OPEC - Flexitanks
They are used in conjunction with all types of OPEC marine pollution equipment and others to store recovered oil from polluted water. Standard capacity range between 5 and 100 tonnes. As well as for oil, the tanks can be made to order for use to store potable water and chemicals. flexitanks are a perfect ancilliary to force 5 and force 7 oil recovery systems.
The TOWED FLEXIBLE STORAGE TANKS are available in various sizes and consist of a long cylindrical bag with a tapered nose constructed from high tenacity nylon fabric coated each side with polyurethane.
All seams are glued welded and stitched where necessary, and sealed with tapes, also of polyurethane coated nylon cloth. The tapered nose is finished with a strong aluminium fabrication to which the tow rope is shackled.
The tail of the cylinder is less finely tapered and is closed by means of aluminium clamps which, when removed, allow the T.F.S.T to be entered for cleaning and inspection.
The T.F.S.T floats at the surface when loaded with a cargo, having density less than that of the surrounding water and, because of built-in buoyancy, it also floats when empty and therefore may be easily towed or moored if required in the unloaded condition.
