AKVA puts trust in a ring that won't rust

Aquaculture supply giant AKVA group has entered into an agreement with Carl Stahl to purchase the Alfaring mooring system with two associated patents. The transaction was completed yesterday.

Alfaring is a mooring system that is specially adapted to floating fish farms. The main component of the system is a flexible coupling ring in polyurethane (with an endless steel rope as core) which acts as a coupling point for anchor lines and an attachment point for a buoy in a frame mooring. 

AKVA says the system has low weight, long service life and long inspection intervals, and is designed to reduce the risk of tears in the net or mooring line.

Less corrosion

The system satisfies the requirements of Norwegian Standard 9415 that apply to floating fish farms.  

“One of the biggest advantages of Alfaring as a connection point is that we avoid more steel components,” said AKVA mooring products manager Roar Østebøvik. 

“This will not be exposed to corrosion in the same way as a traditional connection point, and this will make us better able to deliver to the markets that increasingly demand steel-free solutions.”
