Two-thirds of the Royal Navy’s surface fleet is moored in the HM Naval Base in Portsmouth. One of those vessels is the HMS Queen Elizabeth, the lead ship of the Queen Elizabeth class of aircraft carriers, the largest warships ever built for the Royal Navy of the United Kingdom and capable of carrying up to 60 aircraft.

Quick Release Mooring Pulley

Mampaey already supplied four Quick Release Mooring Pulleys for HMNB Portsmouth in 2016, for the Middle Slip Jetty, and two in 2015 for the Victory Jetty. All Pulleys have a Safe Working Load (SWL) of 180 tons and are outfitted with a Hydraulic Remote Control System and capstans.

This year Mampaey supplied two additional Quick Release Mooring Pulleys. The units of this order are located on the second operational berth on the Victory Jetty.

The advantage of the Quick Release Mooring Pulley is the reduction of fixed mooring points: instead of two conventional Quick Release Mooring Hook Units only one Pulley is used. The mooring line runs from the vessel and loops around the Pulley to return to the vessel, where it will be secured on the vessel’s deck bits. This saves space on the deck of the vessel: only one winch is needed to create two mooring lines.

With the Quick Release Mooring Pulley the force concentration on each rope is equalized because the friction in the sheave rotation is minimized. Same as our Quick Release Mooring Hook Units, the Pulley’s can be outfitted with a Remote Control System to release the hooks from a distance in case of an emergency.
