During a TTS verification at Kårstø Processing
Plant there where raised a non-conformity to
Statoil specification and requirements with
regard to temperature rise in substations when
HVAC
is shut down. One could not find any
documentation on whether Statoil were compliant
with
specifications and requirements. This finding
is further implemented and followed up as a
deviation to TR2237 [3] and in the Total Risk
Analysis[App. D,D04] at Kårstø Processing plant
to
a situation where gas is detected in the air
intake of a substation and one have to shut
down the
HVAC.
The purpose of this thesis is to find the
temperature increase inside a substation when
HVAC is
shut down due to gas detected in the air
intake. To find the temperature increase one
have to
identify heat load to the room and heat leaving
the room.
By comparing measurements, experimental data
and a numerical analysis good enough to make
decisions on when or if one have to close down
the substation. Results from the numerical
analysis
will be seen in comparison with statutory
regulations and internal specifications and
requirements.
Measurements and experiment were performed
during normal operation of the plant, and it
took
place at one of the substations placed in or
near area where one have the highest
probability of
seeing a gas leakage.
