It is equally important that aviation fuel transportable storage tanks are located where they are easily accessible by the installation or vessel cranes to facilitate re-supply. Also, the storage tanks should be in an area where they are free of ‘dropped object’ risks from routine crane operations.
Aviation Fuel transportable tanks should be located in a bunded area separated from other bulk liquid supplies.  The bunded area should be sized to contain at least 110% times the volume of the largest sized transportation tank used.
Generally, these tanks are supplied with either 600 imp.  gallon or 1000 imp. gallon capacity.

To assist with locating the transportable tanks during loading or back loading, the bunded area should have a substantial purpose made steel frame around its perimeter to act as a guide and buffer system.  This is particularly important on floating structures and vessels where restraining the tanks from movement due to vessel motions should be fully taken into account.
A suitably specified, rigid pipe system will normally be installed for interconnecting fixed aviation fuel storage tanks to the pumping system (skid mounted).
The supply to fixed aviation fuel storage from transportable tanks, or where no fixed tanks are used, will normally be achieved by using flexible hoses from each transportable tank coupled to a rigid piped gallery.  It is imperative that the flexible hose, coupling and tank are all properly bonded.  
11.7.4.3 Aviation Fuel Pumping System
The aviation fuel pumping system and ancillary equipment (normally skid mounted) should be designed and located to achieve good operating efficiency with easy access for routine maintenance.

11.7.4.4 Aviation Fuel Dispenser
The aviation fuel dispenser, ancillary equipment, supply system, stand-by and manual systems should be designed and located to achieve good operating efficiency.

Locating the fuel dispenser skid on the helideck, adjacent to the safe landing area needs to be well thought out to ensure safe and easy access for refuelling operations, routine maintenance and annual strip down, inspection and re-certification.
The skid should have a ‘steady red’ light mounted on the top and connected to the system to indicate when the system is in operation.  The light should be visible from all areas of the helideck.
Skid positioning on the helideck along with layout of the skid system components and any access panels should fully take into account routine and annual maintenance programmes (e.g. filter pack removal).  
Routine fuel system and fuel quality checks should be capable of being carried out simply and easily without risk of contamination (e.g. water / rain ingress).
