Although very few control systems are required to be type approved, many manufcaturers see the benefit of obtaining DNV type approval of their control system or component.

The type approval process will typically entail verification of all environmental parameters such as temperature range and electromagnetic compatibility by detailed examination of test reports.

In addition, standard functionality will be type approved so that this functionality will not have to be documented and tested in detail in plan approval and certification survey.

Consequently, type approved equipment will have less requirements for submittal of documentation for plan approval and the fee for certification survey will be reduced.
