After satisfactorily analysis of mooring analysis it is important to optimize mooring pattern in terms of Opex and capex.
8 mooring lines and anchors can be cheaper than 12 lines arrangement or vice versa.
Proposed anchor patterns shall be checked against compliance of Extreme (Tension and Offset in Intact, Damaged and Transient Condition), Fatigue (Design lifetime with safety factor of 10) and Offloading condition where hawser tensions are in specified limits.
The commercial estimate is covered from the detail design of mooring system until hook-up and installation phase. This estimation shall be based on information gathered from previous projects and latest market cost on the work services and equipment.
These cost components shall include
