Safety Flash 23/24 - November 2024

• LTI: Finger Injury During Emergency Recovery of ROV

  • A worker suffered a finger injury caught between a crane wire and an ROV recovery hook during an emergency ROV recovery.
  • A small boat (FRC) was used to connect the recovery rigging to the crane hook.
  • The worker's task was to release the ROV hook from the crane wire, which resulted in their finger being pinched.
  • Injury caused an amputation to approximately the nail bed of the left ring finger.

• What Went Right

  • A thorough toolbox talk including all relevant personnel.

• What Went Wrong

  • The step of releasing the ROV hook from the crane wire was not identified or risk-assessed.
  • The emergency recovery steps were not sufficiently detailed in the plan or procedure.
  • Fault finding and repair of the latching mechanism on the LARS (Lifting and Recovery System) was not attempted before the emergency recovery.

• Actions Taken

  • Reviewed and updated the emergency recovery procedure and risk assessment.
  • Ensured sufficient detailed planning, including risk assessments and task evaluations, were conducted for emergency operations.
  • Established regular training in various emergency recovery scenarios using the FRC (small boat).

• BSEE: Recurring Hand Injuries from Alternative Cutting Devices

  • Incident 1: A worker was using a damaged cutting device (blade exposed), resulting in a laceration between the thumb and index finger.
  • Incident 2: A worker sustained a laceration to their hand due to a missing blade guard on a cutting device.

• Actions to Take

  • Always follow safe work practices when using alternative cutting devices.
  • Ensure proper maintenance and discard defective devices.

• Hot Work Performed Outside of Permit-to-Work (PTW) Boundary Limit

  • Sparks and hot work discharge fell onto scaffolding boards and a 600V HV electrical cable, causing burn marks.
  • There was no fire watcher available in the vicinity.
  • Less than adequate risk perception.
  • Inadequate risk assessment and communication.
  • No proper communication about the work being performed.
  • No permission was sought prior to starting the hot work.
  • Assumptions about the hot work permit boundaries.

• Vital Safety Information (Height of Vehicle) Found Incorrect

  • A worker encountered an overhead structure while moving a vehicle that had an incorrect stamped traveling height.
  • The actual traveling height was different from the stamped height.
  • Three other trucks in the same fleet had similar incorrect height measurements.

• NTSB: Crane Wire Failure

  • A crane wire on a cargo vessel parted while offloading a wind turbine nacelle.
  • The nacelle (69 tonnes) fell back into the cargo hold.
  • Estimated damage was US$3-5 million.
  • The load was 86% of the crane's maximum rated capacity. The lift was made within 19 meters of the crane base, which was certified by a third-party contractor.
  • There were no fatalities or injuries, and no pollution.
  • Post-incident inspection found no evidence of issues with the hoisting equipment or the crane.
  • Probable cause: undetected corrosion and wear in the hoisting wire strands.
  • Examination revealed external corrosion and pitting in the wire ropes, necessitating a closer look at maintenance procedures for wire rope.
