double skinned pipes with diameters sized 110 mm / 125 mm. The fuel delivery bowser

driver, shall therefore just select which tank/tanks to fill (as instructed by MFT) by

simply connecting the bowser’s discharge hose pipe to the 4" inlet port with dry break

coupling (to prevent cross filling and contamination) and manually operate the quarter

turn valve numbered / marked like its corresponding storage tank. This system is

capable of delivering a maximum flow rate of 800-1,000 lts/minute, using the bowser’s

transfer pump. Each tank shall have a top entry point equipped with an ‘Overfill

Prevention Device’ in accordance with EN 13616 Type A, to match with a 110mm /

material and diameter. The manifold shall then feed at one end, the inlet side of 2 fuel

filters described in more detail later, while at the other end, it shall have a manual valve

with a blanked flange end connection which would be utilised in the future when more

fuel storage tanks are added.

Each storage tank and additive compartment shall also have, at its lowest bottom

position, a remotely / or manually (with over-ride) operated ‘wash-out’ valve (using

flanged dismountable connections) to enable the emptying of every tank for cleaning

and inspection purposes. Downstream of the ‘wash-out’ valve, there shall be a

galvanised steel suction bowser spherical female connection fitting to enable every

tank to be emptied, whenever required.

The station operator shall have the means to manage any individual tank outlet valve,

to supply & operate the dispenser units either via remote operation from a dedicated

panel, with LED valve status indications showing ‘Open’ / ‘Closed’ / ‘Over-Ride’ or else

via localised manual valve operation. Delivery valves shall be of the normally closed

type, while all valves on the outlet and inlet sides of the storage tanks, shall have the

possibility to be locked in their closed position.

3.4 Fuel Filtration – On tanks’ outlet manifold

Diesel fuel (EN590) pumped out from the storage tanks, shall be filtered through a

dual assembly of suitably sized leg mounted Racor RVFS SS Series filters with

reusable silicon treated or synthetic fibre (25 micron) fuel filters. Each filter assembly

shall be installed with its own differential pressure gauge, so as to monitor the need
