Key Additional Systems for a Feed Barge Would Include:

• Barge Control: A module in AKVA connect that keeps track and oversight of all processes on the barge. AKVA connect enables monitoring of all onboard systems (tank levels, operating parameters, alarm systems), and allows for remote operation externally via barge control.

• Silage System: An important system onboard the barge is the treatment of dead fish. To maintain silage as a valuable product, it is crucial to process the raw material and the subsequent processing. AKVA group has designed a safe and efficient processing facility that gives customers the option to customize for the desired process method and capacity per location. AKVA group has designed a two-stage and high-capacity silage system that ensures a stable and valuable silage product from the dead fish.

• Power supply: Our feed barges can be delivered with generator operation, hybrid operation with battery systems, or prepared for shore power. In some cases, a combination of these power supplies may be relevant. Hybrid power supply reduces generator operating time by 50-90%, cuts diesel consumption by up to 60%, and similarly reduces CO2 and NOx emissions. Hybrid operation can also be used for "peak shaving" to handle power peaks, even in a shore-powered facility which can reduce the sizing of both equipment and cables. Hybrid power supply significantly reduces the environmental footprint, and in combination with renewable energy sources and energy-efficient technology like waterborne feeding, good environmental results can also be achieved.

HSE and safety

AKVA group delivers feed barges that meet current HSE requirements in close dialogue with customers. Our products are intended to be perceived as a safe and secure workplace. All our feed barges come with fire and safety systems, where the water integrity of feed barges is secured with watertight bulkheads. Additionally, AKVA group has also chosen to install 2 bilge pumps in each bulkhead for secondary protection. There is also an option to monitor watertight doors within AKVA connect. The barge also has the possibility for other support systems like freshwater systems, industrial water systems, septic systems, diesel refueling systems, lifting systems, and more.

Exposed barge models

As the competition for fjord-near locations is intense, several new setups are being moved to more exposed locations. In this context, since 2015, AKVA group has included as part of our standard portfolio; barges for exposed locations. With our unique V-design on the barges and optimized design, we have established some barge models that are certified for up to Hs 6.5 to both withstand the great environmental forces and still be operable. The models are developed through analyses and testing and have a good track record in the market over the last 10 years. The fleet is designed with high loading capacity (minimum 600 tons of feed) for remote operation at locations where daily access is not possible due to bad weather. Our exposed models are therefore designed to be reliable, even on days when they must be remotely operated. Contact us for more information and how we can customize your feed barge for optimal operation.

Regulations for barges

Our barges are built according to definitions and specifications that comply with Norwegian regulatory requirements. NS9415:2021 is the current regulation for aquaculture facilities that underpins all our designs, also internationally along with Nytek23. Electrical installations are designed and built according to the current NEK400 regulation, and the feed barges are normally supplied with a TN-S 400V 50 HZ system in accordance with FEL, NEK for Aquaculture Facilities and Machine Regulations.

Network and IT on the barge are designed and delivered according to the NEK700 regulation. Ensuring that the fleet complies with all applicable HSE regulations is an important part of the design. AKVA group has also delivered facilities in accordance with Class-objects in our deliveries to Canada and is also familiar with deliveries to other "flag-nation" that we adapt our design to meet various requirements for certification or classification in our international deliveries.

Engineering resources

Our fleet team consists of highly qualified and experienced personnel both within aquaculture, but also ship design and building. AKVA group owns its own barge designs which we develop and standardize together with customers over time. Our designers are familiar with current regulations and design for an optimized product according to the customer's expectations and security. By having our own design resources, AKVA group also has the opportunity for custom design that goes beyond our standard portfolio. The design office also has opportunities for other design tasks such as conversions, optimization of existing facilities, or calculations.

Life extension

In cooperation with certification bodies, AKVA group's design department has also established a service around life extension on older feed barges. Contact your nearest service station for more information about the service.
