As the world population grows and the demand for seafood and fish increase, the strain on wild fish populations and the environment increase along with it. But, even as aquaculture operations have stepped in to help supply the demand for fish, environmental challenges remain. For example, poorly constructed net pens and mooring systems cause failures that lead to fish escapes. To prevent these issues and ensure consistency across all aquaculture operations, Norway developed the NS 9415 standard, which has been adopted by many major producers, as the standard for design. When organizations follow the NS 9415 certification process, it helps ensure that fish farms are environmentally safe and structurally sound.

What is NS 9415 Certification?

NS 9415 is a standard that guides the site surveys, risk analysis, design, dimensioning, production, installation and operation of an aquaculture facility. Rather than establishing your own guidelines, it provides a proven framework that an organization can follow. In addition, NS 9415 defines the requirements for the components of a fish farm including:

  • Net pens
  • Floating collars
  • Rafts
  • Mooring equipment and connections

And, any extra equipment needed to run the operation effectively. Furthermore, it details how to operate marine fish farms so they are acceptably escape-proof.

The Importance Of NS 9415 Certification

Building to this standard means that the cage can withstand a level above the critical breakage point. Otherwise, it won’t be certified.

In fact, when companies follow this standard, it reduces the risk of technical failures and the resulting escapes. In a study conducted by the Norwegian Directorate of Fisheries, facilities that meet these standards experienced a significant decline in salmon and rainbow trout escapes.

How Poseidon Builds NS 9415 Into Their Structures

Poseidon incorporates NS 9415 standards into our entire workflow including the design, development and implementation process.

Site Surveys

Our objective with any aquaculture development project is to protect the environment, reduce risk and optimize production. Our site surveys are designed to do just that. We follow a number of steps including estimating and evaluating the biological carrying capacity of farm sites and determining the baseline upon which allowable fish and farm density are based.

Risk Analysis

It’s essential to analyze wind, wave and current data and run simulations to mirror worst-case scenarios for the each specific farm site. This analysis allows us to determine the components to use for the mooring grid and the type of cage construction required.

Design And Dimensioning

The risk analysis guides the design and dimensioning process dictating the type and size of chain, rope and anchors to use for the mooring grid. We only use parts and equipment that are certified for use under the specific conditions defined during the risk analysis.

Production

We then drive net pen and mooring system production by incorporating the survey, risk analysis and design and dimensioning information. When you achieve NS 9415 certification, it means that the designs and components are certified and the risk analysis simulations meet the guidelines for each specific site.

Poseidon Ocean Systems

The NS 9415 standard will help further elevate environmental standards and decrease the amount of fish escapes at aquaculture operations. Our commitment to these standards coupled with our research and development efforts will lead to better outcomes for all constituents.
