Our services

The site survey is the work that leads up to the determination of dimensioning values for wave heights, current conditions and other relevant environmental forces at a site. The results of the survey are gathered in a site report which is used as the starting point for further work to ensure compliance with the NYTEK23/NYTEK Regulations. It defines frameworks for the use and dimensioning of technical equipment. The report also provides useful and relevant information on environmental factors so that fish farmers can adapt their quality system's procedures and routines and have the necessary risk analyses conducted.

A mooring analysis is intended to determine the dimensioning loads in a site's mooring system. A number of small and large factors influence the dimensioning loads, including environmental forces, mooring components, main components and the location.

The mooring analysis is the mainstay of the initial work carried out at a site. A mooring analysis is intended to add value and be beneficial to you as a customer, and our goal is the optimal design of your mooring system. We want you as a fish farmer to feel confident that your fish-farming facilities are dimensioned for the prevailing conditions at given sites and that your assets are safeguarded in the best possible way.

A site certificate is an assurance that your fish-farming facility meets all of NS 9415's technical requirements. The issuance of a site certificate means that you as a fish farmer can feel confident that your fish-farming sites have equipment components that make them safe and that the equipment is correctly connected and in the right position at your facility.

Since the requirement of a site certificate was introduced in 2012, DNV has issued several hundred site certificates for fish-farming sites along the entire coast of Norway.

Main components and construction parts for mooring must have a lifetime extension before use beyond the designed working life laid down in the product certificate, the validity period of the main component certificate or the validity period of a previous lifetime extensions.

It is a prerequisite for extending the lifetime that the main component complies with requirements in regulations and standards throughout the period for the lifetime extension. The main component shall have sufficient capacity to withstand given loads and load combinations for a period under given environmental conditions.

The main component's current condition must be evaluated on the basis of technical documentation (for example from design, manufacture, installation and use of the component), inspection, analyses, relevant tests and measurements. The main component's future condition must be evaluated on the basis of the main component's current condition, the effect of the expected environmental impact and use as well as mitigating measures. The evaluation shall, with sufficient consideration of uncertainty, conclude on a lifetime extension period where the main component meets the requirements.

Before issuing a lifetime extension certificate, the following shall be carried out:

1. examination, to the extent necessary, of the main component or representative structural parts in the mooring system
2. the condition of the main component or structural part must be determined at the time of verification with sufficient consideration of uncertainties and
3. determination of any anticipated deterioration in the capacity or durability of the main component or structural part.

Why work with us?

Since 2004, we have had the pleasure of certifying main components and extra equipment in all the categories stated in the NYTEK23/NYTEK Regulations. We have provided services to the aquaculture industry since 1988 and this long experience has given us wide knowledge of the fish-farming industry. We can see how the rules and standards are connected so that you receive a chain of aquaculture regulations' services that are cohesive, beneficial and meaningful.
