Summary
Investigation of a stabilised-oil release on Statfjord C during inter-platform transfer and loading-pump isolation. It examines drainage restrictions, fire-seal defects, missing tank-level alarms and inadequate isolation and concurrent-work arrangements. Oil reached the installation and sea; disturbed evidence and unverified valve conditions limited certainty about contributory causes.
