Summary
BSEE examines a subsea jumper failure in Mississippi Canyon Block 209 that released an estimated 16,000 barrels of oil. Internal corrosion and stresses from pipeline movement caused the failure. The report analyses flow-meter inaccuracies, delayed leak recognition and startup pressure trends, recommending infrastructure scrutiny and improved subsea leak detection training.
