Mooring Calculation - Rev 0

This document contains input data and calculations for mooring a vessel. It provides information on vessel dimensions, environmental conditions like current and wind speed, and calculates the total longitudinal and lateral forces on the vessel from current and wind. It then calculates the tension force in different mooring lines based on their length, angle and direction factors. The total tension force summed across three mooring lines is 1.2167 kilonewtons.
