Challenges in Selection, Anchorage Design, and Installation of Mooring Hooks on Existing Structures
Quick-release mooring hooks have become increasingly popular for use in design of new mooring systems, especially for larger vessels. Hooks offer several operational and safety benefits over the standard bollards or cleats. Such benefits include the abilities to release mooring lines without detensioning the lines, release mooring lines remotely from a distant control location in possible emergency situations, as well as monitoring of tension in the mooring lines while a vessel is at berth. In addition, mooring hooks are increasingly being required for new installations by local rules or regulations. This paper discusses the challenges and solutions for designing and installing quickrelease mooring hook at existing marine facilities. Examples of successful installations and typical technical challenges are presented.
