Windenergy News: A new revision of DNV's offshore standard for Integrated Software Dependent Systems

DNV is experiencing increasing demand from the drilling market for this kind of service and has now established a separate dedicated section in order to better serve this growing market.

Based on continuous dialogue with owners, yards and suppliers, DNV’s offshore standard OS-D203 has been revised in order to clarify the requirements for assigning an ISDS class notation to an offshore unit as proof of compliance with the standard as well as to clarify the text in general and remove known inconsistencies. In addition, the standard has become more user-friendly.

The following are the main improvements in the revision:
• It has established scope and confidence levels for selected drilling and well-intervention-unit systems in the standard
• The information and defined expectations related to roles and responsibilities for each involved party in an ISDS process have been structured and clarified
• The standard text has been restructured to make information more easily available
• Security requirements have been introduced

“The revision means that yards, owners and suppliers may now more easily determine the scope and efforts related to implementing ISDS,” says Knut Ording, manager of the newly established Systems and software reliability section. “Besides, the standard is now more user-friendly and it’s easier to find information,” he says.
DNV realises that addressing the safety and reliability of integrated software dependent systems is now becoming an industry standard for offshore drilling units. That is why it has geared up to deliver high quality ISDS services to this industry in key locations such as Norway and Korea.

Early mover
DNV was the first classification society to set the safety and reliability of integrated software dependent systems on the agenda. The basis for the Enhanced System Verification (ESV) class notation was launched in 2005 and ISDS was introduced in 2009. The demand for these services is growing rapidly.

“It’s also important to underline that all DNV’s technology development takes place in close cooperation with our customers and end-users,” says Knut Ording.
