Temperature and pressure
sensors from ABB’s UK
Measurement Products business
are helping to maintain
safety at the world’s largest
above ground liquid natural
gas (LNG) tanks at National
Grid’s Isle of Grain terminal.

The four 50m high tanks,
each holding 200,000m3 of
LNG, form Phase 2 and 3 of
an expansion plan that will
eventually see the site capable
of supplying 20% of the UK’s
gas demand.
For Phase 2, ABB supplied
93 temperature units and 99
pressure units, while for Phase
3, it supplied 74 temperature
units and 140 pressure units.

These are used throughout
the site on every process line
and utility. A typical application
is in the management of
boil-off vapour, which is
produced in the tanks and
liquid fill lines during normal
operations by heat transfer
from the surroundings.

Some of the ABB
temperature sensors are of a
clamp-on design, allowing
them to be installed around
the pipe work rather than
needing to intrude through
the pipe wall.
