DNV-RP-F401 Electrical power cables in subsea applications

Recommended practice

Edition 2019-09 - Amended 2021-09

This recommended practice (RP) is to be used as a supplement to ISO 13 628-5 /1/ with regards to electrical power cables. This ISO standard does not give requirements to such cables on a detailed level. This RP covers additional requirements for power cables being submerged in seawater at large water depths and/or being exposed to dynamic excitation, e.g. when suspended from floating production units.

The RP is intended to be used together with /1/. In case of conflict between the ISO standard and this document the ISO standard shall prevail.

It is a pre-requisite that power cables are designed and fabricated according to existing IEC standards.
