BEAP Fuel & Gas Condition Assessment Guidelines

The purpose of this checklist is to outline the requirements for AECOM condition assessment of reticulated Defence Fuel Installation (DFI) assets, as part of the Base Engineering and Assessment (BEAP) project.

It is important to note that a DFI does not include[1]:

-Fuel facilities which are part of another fixed infrastructure where the fuel assets are not independently managed as a stand-alone system, and/or are classified as consuming assets (e.g. storage tank for a back-up power generator, provided it is recognised and managed as part of the parent power generation asset);

-Mobile fuel assets such as tankers (e.g. RAAF refuelling tanker, bulk liquid fuel, tanker truck fuel or tank pump assembly);

-Field-deployable fuel assets (e.g. bulk bladders, petroleum oils and lubricant points/kerbside refuelling points or forward arming and refuelling points); and

-Navy re-supply vessels (e.g. auxiliary oilers or auxiliary oiler replenishment).

Fuel Asset Condition Parameters

Unserviceable / Poor / Fair / Good / As New
Fuel Storage Tanks
Age / Tank cannot be filled due to leaks or contamination / Tank installed >10 years prior and not repainted and / or inspected / Tank installed 5 - 10 years prior and not repainted / inspected / Tank installed >5 years prior but recently repainted and / or inspected / Tank recently built and commissioned within the period of ≤5 years prior
Material of Manufacturer / No evidence that steel tank is internally painted / Single-wall steel Installed >10 years prior and not repainted / inspected / Single-wall steel installed 5-10 years prior and not repainted / inspected / Stainless steel or double-wall or single-wall steel installed >5 years prior but recently repainted and / or inspected / Recently built and commissioned within the period of ≤5 years prior
Coating System
Inspection Records
(DFI (A)+DFI (N)
Only) / No evidence that steel tank is internally painted / Tank installed >10 years prior and not inspected or records inconsistent / Tank installed 5 - 10 years prior and not inspected or records inconsistent / Internal tank inspection conducted every 5 years or less with records / Recently built and commissioned within the period of ≤5 years prior
Inspection Records
(DFI (G)+DFI (P)
Only) / No evidence that tank/s have been inspected or as-installed information not available / Tank installed >20 years prior and not inspected or records present but inconsistent / Tank installed 10 - 20 years prior and not inspected or records present but inconsistent / Internal tank inspection (i.e. pressure test) conducted every 10 years or less with records / Recently built and commissioned within the period of ≤5 years prior
UST Installations / Evidence of leakage and/or corrosion / Single-wall tank installed >10 years prior without inspection records or evidence of cathodic protection system / Single-wall tank installed <10 years prior with cathodic protection system in documented in as-built information / Double-wall tank or single-wall tank with documented corrosion protection maintenance records / Recently built and commissioned within the period of ≤5 years prior
Tank Installation Cleanliness / Surrounds / Not capable of functioning and requires full replacement / upgrade / Significant dirt and debris build up that would affect maintenance and / or severely limited asset serviceably / Some dirt and debris build up that may affect maintenance and / or some loss of asset serviceably / No dirt and debris build up with documented maintenance records as per BFIMI / No dirt and debris build up and recently installed ≤5 years prior
Fuel Hydrant Lines
Age / Line is not currently in use and has no decommissioning report/s. / Tank installed >20 years prior and has no testing or as-built information / Line installed 10-20 years prior and has inconsistent as-built information and inspection records / Line installed 5-10 years prior and has good as-built documentation or installed >10 years with recent inspection records / Line recently built and commissioned within the period of ≤5 years prior
Material of Manufacturer / Line is not currently in use and has no decommissioning report/s. / Line is > 20 years old, within no documented cathodic protection system or test records / Line is < 20 years old, constructed of steel, has a documented cathodic protection system with inconsistent test records / Line is constructed of steel and has a documented cathodic protection system with consistent testing records or is of double-wall non-corrodible construction. Also, an active leak detection system is in use. / Line recently built and commissioned within the period of ≤5 years prior
Valve Pits and Hydrant Pits / Components within pits cannot be used to to seizure / missing parts. No capability exists to issue fuel. / Water in combination with severe corrosion of components is present. Serviceability would be affected, impacting on capability to dispense fuel. / Evidence of water ingress and/or some corrosion. Some water remains in pits and cracking is visible in walls / floor. Serviceability would be somewhat affected / No evidence of water ingress and/or corrosion. Pits are well sealed. All protective caps are in place. / Line recently built and commissioned within the period of ≤5 years prior
Fuel Hydrant Pumps
Corrosion / Pump does not work. / Evidence of severe corrosion, no maintenance records are present and pump is outputting less that design flowrates. / Evidence of surface corrosion (i.e. wear of painted coatings, data plate). No maintenance records present however serviceability is not impacted / No evidence of corrosion and maintenance records present along with as-built documentation. / Built and commissioned within the period of ≤5 years prior
Age / Pump does not work. / Pump is >20 years old and is exposed to ambient conditions / elements. / Pump is 15-20 years old and is provided with some cover from ambient conditions / Pump is ≤15 years old and is provided with full cover from ambient conditions / Built and commissioned within the period of ≤5 years prior

Gas Asset Condition Parameters

Unserviceable / Poor / Fair / Good / As New
Gas Pipelines
Age / Pipeline is no longer in use and has no decommissioning report/s / Pipelines are >20 years old and have no as-installed information and evidence of ongoing leaks / Pipelines are 10-20 years old and have limited as-installed information. Some evidence of service interruptions / Pipelines installed 5-10 years prior and have good as-built documentation or are >10 years old and have comprehensive maintenance records / Pipelines recently built and commissioned within the period of ≤5 years prior
Pressure Regulation Stations
Corrosion / Station is no longer in use and has no decommissioning report/s. Also applicable if stations are leaking. / Corrosion severe with components installed exposed to elements. No sign of maintenance records either written or service tags. / Show signs of surface corrosion and/or fading of painted components. Service tags no longer readable. Area surrounding stations not well maintained. / Well maintained with no visible signs of corrosion and adequately protected from elements. / Pressure regulation stations recently built and commissioned within the period of ≤5 years prior
