Site of Special Scientific Interest (SSSI) and is protected under both UK
and European Union legislation.

In addition to obtaining the necessary environmental permits, the
project team worked closely with environmental agencies to ensure
minimal impact to the area. The timescale was short – there were only
62 days in which the pipeline could be laid to fit in with the rhythm of
nature, as well as the refinery’s shutdown. It was a window not to be
missed, so no wonder planning began four years before, in 2011.

The team conducted bird count surveys over a 12 month period before
work began to understand feeding and breeding patterns and made
a conscious decision to stop the project’s preliminary work over the
winter period to prevent any impact to the feeding patterns of important
migrating bird colonies.

To protect and preserve the coastline and its flora and fauna, all workers
travelled via the river - even the kit came to the site on water. Cranes,
diggers… everything came by sea. The workers even stayed in a floating
hotel and river taxis transported workers to and from the nearby port of
Grimsby.

The team also conducted topographical surveys of the shoreline using
drones and inspected the beach and seabed for unexploded bombs
from the Second World War. Despite this extensive preparation, one
such bomb was dredged up during the project!

So, let’s get down to specifics. To align with the refinery’s turnaround
schedule, it was necessary for the pipeline project to fit within
