Environmental Statement - Maersk Oil

Major accidental
events
Other environmental
aspects
B ‐ 14
Oil spills Loss of hydrocarbon
containment.
Produced water spills Accidental discharge of
produced water above
regulatory limits of 30mg/l.
Failure of flow‐
lines/loss of well
control /fire
explosion / loss of
FPSO/ rupture in
offloading line
Consumption of
materials
Loss of platform, process plant
or well control resulting in
release of gas and condensate
which may be ignited.
Use of finite materials such as
chemicals and steel. There will
be a increase in chemical use
with production, however
there will be no changes to the
surface infrastructure.
Impact dependent on spill volume and weather conditions.
Birds are most sensitive offshore receptor. Also affected are
plankton, fish/fisheries, seabed animals & marine mammals.
Affect also on amenity value, property (e.g. vessels in
marinas) & commercial interests.
Likelihood Consequence Risk
2 2 Low
Oil in water can result in narcotic, toxic, teratogenic impacts
and enrichment etc.
Likelihood Consequence Risk
3 2 Low
Atmospheric emissions contribute to global warming, acid
deposition and ozone depletion. Damage to commercial
fisheries. Sediment and water quality impairment. Potential
discharge of hydrocarbons and various chemicals and gases
into the environment. Fire‐fighting system comprises of CO2,
water and foam (no halons released). Physical disturbance to
other sea users.

Balloch Field Development Environmental Statement
Procedures in OPEP are
implemented should a spill occur.
Training is provided on oil spill
response to all appropriate
personnel. Maersk are members
of OSRL (OSRL are on standby to
provide oil spill clean‐up when

includes reducing the quantity of
materials used.
Appendix B ‐ Environmental Assessment
Low impact.
Negligible impact.
Spills may cause local
elevation of hydrocarbon
levels and contamination
and toxic effects and
socio‐economic impacts
to fishing, and tourism.
Mitigation measures will
ensure actual risk of a
spill are within tolerable
levels.
Materials used on the
platform indirectly
impact natural resources.
Low impact.
