The design capacity of the rest of the mooring equipment onboard (winches, bitts, fairleads, rollers, ) depends on this value. Mooring lines may also assist in heaving the ship alongside a birth and can be used to assist in unbirthing. The higher mooring loads and longer design life requires consideration of several factors which are discussed here. 1619. Slack means very slack, with lots of droop, almost touching the water. The easiest solution is to slack the mooring lines before each measurement. 1/Circ. The advantage of a mooring over anchoring the vessel is that the moorings are typically selected based on the harbor bottom sediment types and are weighted and/or secured to better hold and secure various types of vessels in that area. This plan presents specific information regarding the towing and mooring fittings aboard the vessel, the mooring lines, as well as the arrangement of mooring Fig. 5 for semi-taut line mooring, and to 2 for catenary mooring. This paper points out the need, created by the advent of mammoth oil tankers, for using more efficient mooring patterns than those used in the past. Check Compatibility: Ensure new mooring lines are compatible with existing winches, capstans, and mooring systems to prevent increased wear and ensure efficient operations. 5 method of applying load of towing or mooring line including limiting fleet angle, i.
