A new and more user-friendly version of DNV’s offshore standard for Integrated Software Dependent Systems (ISDS) has been issued. 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
