DNV moves to standardise subsea certifications

Subsea standards: DNV's Bjorn Sogaard points to costs benefits

Classification and certification group DNV GL has launched a new certification scheme for subsea equipment and components, aiming to help operators and suppliers cut costs and delivery times.

The Oslo-based group has worked with both operators and suppliers to establish a system for certification that covers several product groups such as subsea trees, wellheads, tie-in systems, control systems and manifolds, as well as related work processes and documentation standards.

Introducing more standardisation is seen as essential to bring down costs, which have surged in recent years, Bjorn Sogaard, segment director for subsea and floaters at DNV GL, said at the ONS conference in Stavanger.

However, many suppliers have pointed to operators as part of the problem, as all the major players have their own additional requirements and documentation demands that push lead times and costs higher.

“Standards are like toothbrushes – everyone wants one, but they want one of their own,” said Anders Husby, head of the department for wells, subsea and risers at DNV GL. “But operators do see that the extra requirements are part of the cost picture, so there is room for things to happen.”
