In order to support rig owners and operations in reducing downtime caused by integration and quality issues with software-intensive control systems, DNV is publishing a Recommended Practice.

As the rate of technology innovation increases, offshore rigs are becoming more and more dependent on complex software-intensive control systems. These are providing great opportunities but are also inducing new problems, often related to the commissioning, integration and operational phases.

Challenges often occur as there are many different components from a diverse group of suppliers required to work together. Successful development and integration is not always the case in this setting.

“The results of a software crash or integration issues may be a significant loss of revenue due to delayed rig commissioning and rig downtime. Misunderstandings about requirements and responsibilities often contribute to these problems. Furthermore, many critical integration and verification tasks ‘fall through the cracks’,” says Annie Combelles, the head of DNV’s IT Global Services unit.
