Mooring analysis

header_fortøyningsanalyse
 

A mooring analysis calculates the loads in mooring systems on fish farms, feed barges or other floating structures. The goal is to calculate a cost efficient mooring configuration, while still providing safe solutions, reducing the risk of escaping fish. Aquastructures is accredited by the Norwegian government to perform mooring analyses, for the fish farm industry, in accordance to the NYTEK regulation.

Fish farms

To reduce the risk of escaping fish, the Norwegian authorities demand design verification on all types of floating fish farms. This means that the mooring system should be analyzed with the use of calculation software. When advising in design of new mooring configurations, we always do our best to calculate a cost-effective solution, while providing mooring systems that reduce the risk of escaping fish. We are an accredited company, and therefore allowed to issue mooring analyses as a part of the certificate for the aquaculture installation required by the Norwegian authorities.

Feed barges

For feed barges located near floating fish farms, the NYTEK regulation requires that the barge mooring systems are designed, and analysed by the same principles as for the fish farm themselves. Barges are often sensitive to wave and wind loads, and we can perform analyses both using regular and irregular sea states. This provides accurate calculations of the mooring line loads, and assessment of fatigue problems.

Floating docks and marinas

Mooring analyses of floating docks and marinas are performed in similar manners, as for floating fish farms and feed barges, by using wind, current and wave loads. Additionally, loads caused by one or several boats could affect the load in the system. We have in several occasions contributed to design of mooring solutions for floating docks and marinas.

Offshore oil and gas

Aquastructures provides mooring analyses for the offshore oil and gas industry. Typical analysis are structures and systems moored to sea bed or quays. Through AquaSim, Aquastructures is able to analyze and visualize the system, and internal reaction forces. Vessel, platform or system motions may be included to the dynamics, either by direct calculation or by RAO.
