Found that clearance mm) between the riser and the 13 3/8" BOP test plug would make it impossible for the lid to pass the plug. Drained BOP to get dry access to BOP through ram door. Prepared fishing magnet on rope.
16:15 - 19:00: Opened LPR ram doors. Drained riser. Picked up to 11,5 m MD in order to get pictures of fish. Got pictures showing lid resting on top of 13 3/8" test plug.
