Transforming Net Repair in Norwegian Salmon Farms: Apama ROV NRS for Efficient and Safe Aquaculture Solutions

Background

Norwegian salmon farms must comply with strict environmental and safety regulations. Traditional net repair often involves divers, leading to high operational risks and downtime. The need for a safer, more efficient solution was clear.

Challenge

To replace high-risk diving operations with a compact, remotely operated system capable of meeting Norway’s stringent repair standards (minimum 80% net strength retention for 18 months).

Solution

The Compact Apama ROV NRS, developed by Southern Ocean Subsea (SoSub) in collaboration with ROVrespons (Norway), integrates advanced tooling and net identification technology utilising Industry 4.0 practices. It allows single-operator deployment from small vessels and is controlled remotely from headquarters, providing a reliable, single-operator solution for aquaculture maintenance.”
