Sandefjord – Norway
“Biofouling was affecting both water quality and fish health. Weda’s Optimizer keeps our hulls clean and operations smooth.”
— Operations Manager, Sandefjord Aquaculture Site
This aquaculture operator near Sandefjord, Norway, manages a series of floating fish pens and vessel-based support infrastructure. These installations suffer from algae and biofouling buildup, which can increase drag, reduce water exchange, and endanger fish health. Traditional hull cleaning methods require drydocking or diver intervention. By switching to remotely operated submersible cleaners, the operator was able to maintain barge hulls, netting structures, and pen walls with minimal disruption. This approach aligns with Norway’s strict aquaculture standards and improves operational sustainability.
The Challenge
Algae and organic growth on the hulls of support vessels led to reduced fuel efficiency and increased disease risk within the pens due to cross-contamination.
The Weda Solution
The Optimizer — a Weda-designed hull-cleaning robot — was deployed to clean ship hulls while vessels were idle. This allowed for frequent, cost-effective cleaning with no need for dry-docking or divers.
