*** Safety Alert ***
Dropped Load into the Gulf:
Recently during a routine lift from motor vessel to work platform one end of tubing basket came undone from stinger causing one
end of basket to fall dumping approx, 3300-ft of tubing into the Gulf.
2-Two-part slings from the pipe basket holding approx, 3300-ft of 1 ¼-tubing were hooked
up to stinger attached to the big block. Basket was then lifted approx, 20-ft above motor
vessel and over the water when the load shifted slightly causing one of the sling eyelet/D-
ring to pop up striking the safety latch on stinger. Safety latch failed, therefore one end of
the tubing basket fell allowing the contents to go into the Gulf.
Picture; immediately after the incident once Crane Operator This Photo shows the stinger latch and how it was
was able to bring basket safely back on the boat deck shifted damaged for the side force of D-ring once loaded
Photo show’s how slings were doubled up on the second lift to make This picture is a recreation of how the basket
them longer, which increased the angle ensuring a much safer lift was attached. The slings are too short and the D-rings
(Arrow’s indicate what angle was used during the original lift, and appear to sit too high on the stinger hook, therefore
it’s easy to see the extreme angle and how would have increased when the load shifted it caused one D-ring side force to
the safety latch, which failed causing the load to fall
into the Gulf.
Factors to Consider:
Per-installed slings were too short to provide proper angle for correct support throughout the lift.
Dock load out team failed to identify the risk with the short sling set up and went ahead and loaded tubing basket.
Platform Crane Operator and riggers failed to identify potential risk and made the lift.
Some Corrective Actions Taken:
Install a 50-ton clevis to the stinger to assist in stabilizing/centralizing the load to reduce shifting.
Install longer lifting slings to increase lift angle according to SOP’s recommendations and APR RP D-2.
Contact Company that installed slings to the tubing basket to ensure they understand the requirements.
Notify the Dock to ensure that they understand that no equipment is to be transported to the field without being properly slung.
Conduct an on-site safety meeting with all parties to ensure that everyone understands the sling length to angle ratio, and how
important it is to conduct a pre-lift inspection on all loads to ensure a safe lift. Initiate a safety alert and forward to all parties to
assist in minimizing reoccurrence. Produced by: Safety by Design on behalf of Client
