An incident occurred throughout a backloading operation involving two vessels. The occasion resulted in cargo turning into caught after a collision on the receiving vessel’s deck. This abstract outlines the sequence of occasions, contributing components, and key security classes.
What Occurred
Throughout a backloading operation from one vessel to a different, cargo was being lowered onto the receiving vessel’s essential deck. The banksman signaled the crane operator to decrease the hoist and disconnect the stinger. At that second, the opposite vessel skilled sudden rolling, prompting the crane operator to regulate the winch to take care of the block’s place. When the winch was lifted once more, the suspended cargo swung and struck different cargo already stowed on the receiving vessel’s deck, turning into caught.
Why It Occurred
The incident was primarily attributable to the sudden rolling of one of many vessels, which led to instability within the cargo’s positioning. Restricted clearance on the receiving deck created a high-risk setting for collision. Moreover, the cargo was not adequately stabilized in the course of the carry, permitting it to swing unpredictably when hoisted. A delay in communication between the crane operator and the banksman in the course of the vessel’s motion additional contributed to the scenario.
Actions Taken
The crane operator responded appropriately by not releasing the primary block instantly, stopping uncontrolled motion of the cargo. Crew members shortly recognized the difficulty and acted to stop additional harm or harm. The stowage plan was adopted, and the banksman maintained correct signaling all through the operation, which supported coordinated dealing with regardless of the unanticipated vessel movement.
Classes Realized
Conduct thorough toolbox talks centered on vessel movement dangers earlier than lifting operations.
Reinforce the significance of exercising STOP WORK AUTHORITY when surprising situations come up.
Guarantee lifting threat assessments contemplate the potential of vessel motion.
Strengthen real-time communication between crane operators, banksmen, and deck crews throughout dynamic operations.
