DNV Updates Marine Operations Standards for Offshore Wind, Subsea Cables


DNV has made updates to its marine standard covering most offshore assets and operations, including the transportation, installation and removal of subsea cables and relevant wind farms. 

This latest revision of the DNV-ST-N001 standard is its first in five years and follows an external hearing exercise, during which more than 350 technical comments were submitted by industry members. 

The standard itself came about after DNV and Noble Denton legacy standards were combined into one document. It is meant to be applied across marine operations and key engineering requirements relevant to load-out, construction afloat, voyages and installation, as well as the loads addressed in the marine operations’ design. The standard also lays out the requirements from the perspective of the Marine Warranty Surveyor, who reviews these operations.

“Following a high level of engagement from the industry, the latest revision of DNV-ST-N001 further reinforces its position as the de-facto standard used to safely undertake marine operations all over the world providing the needed assurance in the implementation of the energy transition,” says DNV’s Lucy Craig.

“Since the standard was first established, it has been vital that it has remained at the forefront of changes to the industry and these updates will ensure that our customers continue to receive the highest possible standard of assurance.”
