BSEE: A warning on tagline entanglement

BSEE notes:

“Since November 2022, there have been four incidents during offshore operations involving personnel becoming entangled in taglines and lifted with the load. Despite the high potential for injury surrounding the events and operations, none of the occurrences resulted in an injury.

"Similar situations were previously discussed in BSEE Safety Alert 362, Poor Tag Line Awareness Leads to Multiple Incidents."

The following summarises some recent incidents involving individuals entangled in taglines:

• January 2023: While lifting a welding machine from the deck, a crew member moved into the Step Back Area (see Figure 1) and stepped into the coiled tagline and became entangled. The crew member was able to grab the tagline while entangled and was lifted up and swung with the load approximately 4 m off the deck (Figure 2). The Signalman relayed the crane operator to stop the lift, and the rigger and load were lowered to the deck.
  
  
• December 2022: After backloading a bundle of pipe onto a vessel, a deckhand attached the taglines to the crane hook to send up to the platform. When the taglines were lifted, he became entangled in the lines and was lifted approximately 1 m above the deck onto a bundle of pipe where he was able to free himself without injury. A safety stand-down was conducted, and the importance of tagline safety was reinforced to the crews.
  
  
• November 2022: After completing multiple lifts from one deck to another, crane crews were sending a bundle of taglines to the top deck when a rigger became entangled in the lines on the main deck below. The rigger was able to grab and hang onto the tagline while being lifted approximately 3 m. The flagger signalled an all-stop after seeing the rigger in the air and the crane operator was able to safely lower the rigger down without further incident.
  
  
• November 2022: After unhooking a load on the deck of an offshore vessel, a deckhand became entangled in a tagline and was lifted from the deck after the designated banksman signalled the crane operator to start the lift. When the lift began, the deckhand’s leg was lifted approximately 60 cm off the deck, causing the deckhand to become unbalanced. Other crew members were able to support the deckhand’s upper body while the crane operator lowered him down to deck.
