Spill is defined as any loss of containment (oil and chemical) that reached the environment. The spill volume reported should reflect the volume of material that reached the environment only (i.e. not inclusive of any
released volume retained within secondary or other confinement). Reported volume reaching the environment is irrespective of the quantity recovered (i.e. representst the gross volume reaching the environment, not a net volume remaining in the environment).
Oil and chemical spills including oil, oil products, chemicals, and/ or solvents during exploration and production activities.
Spills occurring from support and standby vessels are to be included, but spills of produced water or process wastewater are excluded. Loss of containment resulting from acts of sabotage (such as theft of oil from
pipelines and storage) should be reported. Loss as a result of “acts of terrorism” / attacks on infrastructure should not be reported. Spills of chemical and drilling fluids are also included.
Intentional discharges of drill cutting (only offshore operations exceed 12 nautical miles) during drilling activities are excluded
