Background
Ocado is the world’s largest dedicated online supermarket.
Prior to a devastating fire in February 2019, the Andover
Central Fulfilment Centre (CFC) provided about 10% of Ocado total
capacity and processed over 30,000 orders per week.
During the redesign process, Ocado decided to use Andover as a
petrol test site.
The petrol fuel islands were designed to fuel a forthcoming
petrol hybrid fleet of vans that would, in time, completely replace
the existing diesel van fleet.
The aim was to grow its fleet but also reduce carbon footprint
and move ahead of the UK government’s 2030 ban on non-hybrid.

DesignEarly stages
Vectec was approached in September 2019 by MBA Consulting
Engineers for advice
Client opted to go below ground to maximise the available yard
space.
Then decided to make the new facility diesel and petrol
The size of the required petrol storage raised the question of
Stage 1B and Stage 2 Vapour Recovery

DesignLayout
The final design was a three island facility
Careful layout to adhere to hazardous zoning
Reduced Zone 2 radiidue to VR2

DesignWhy VR2?
Environmental compliance
Permits for Vapour Recovery are issued by a local authority’s
department for control of pollution under DEFRA guidelines. DEFRA
stated in December 2013 (Process Guidance Note 1/14(13)) that any
new service station with a planned petrol throughput greater than
500m3 in any 12 month requires Stage 2 controls.
Alongside the requirement to be compliant with UK environmental
legislation, the biggest driver behind employing VR2 on a
commercial petrol forecourt is safety.
The client decided to put in VR from the get-go in preparation
for hybrid switch

DesignRole of the petroleum licensing authority
Licenses granted either by a local authority’s trading standards
department or by the local Fire and Rescue service.
A petroleum officer would usually expect to be present to
oversee the offload of a below ground petrol tank, as well as to
oversee the pipework pressure testing and finally to oversee the
facility commissioning.
The submission must include as installed drawings of fuel
pipework, tank in ground and drainage; with full technical
specifications and DSEAR risk assessment/method statement
