Brief summary:
HSE:

STOP cards: Total – 38 Seadrill – 28, PTTEPAA - 3, Third Party – 7.
Incidents: 2
#1
At 03:30hrs this morning – Whilst running the 9 5/8” casing the MLS landing collar held-up in the wear bushing. The
plan was to lay out the landing joint that had a small pup joint on top – then pull out and investigate the problem with
the MLS. The single joint elevators (SJE’s) were placed around the full joint of casing and the blocks lifted up. It
appears that all the focus was on the casing collar on top of the pup joint not on the collar between the casing joint
and the pup joint. The SJE’s caught on the collar between the casing joint and the pup joint taking the full weight of
the casing causing the shackles holding the SJE’s to shear. NOPSA have been notified.
#2
While attempting to free the jammed Casing Drive System (CDS) which would not release from the casing string, an
air hoist was routed through a sheave block attached to the Stbd ‘V’ door Samson post and connected to the CDS to
assist in trying to work it free. While applying tension to the CDS the sheave block failed with the sheave section
being flung into the air although still attached to the tugger line. On investigation it was noted that the SWL for the
sheave block was 0·8t being used on an air hoist with the lifting capacity of 5t SWL.
