What is the purpose of a "Trolley" in mooring operations?

The purpose of a trolley in mooring operations is to ease down the bitter end of the chain. A trolley is a movable device used to guide and control the handling of the chain, allowing for more efficient management of mooring lines and chains, particularly in heavy or additional load situations. This function is critical in reducing the strain on both the equipment and the crew during the mooring process.

By easing down the bitter end, the trolley helps to ensure that the chain is stowed or deployed smoothly, preventing sudden jerks or snags that could cause damage or pose a safety hazard. Proper use of a trolley not only facilitates a more controlled mooring operation but also enhances the overall safety and effectiveness of the process.

Other roles described, such as securing a bowline or maneuvering the vessel, do not accurately represent the primary function of a trolley in this context. The correct understanding of a trolley’s function is essential for effective mooring operations.
