HOVIK, Norway - DNV GL has created a new service specification for functional safety certification. This service specification will be applied for the certification of a high-integrity pressure protection system (HIPPS). GE Oil & Gas UK Ltd. has commissioned DNV GL to carry out a third-party inspection and certification of the logic solver element of a product that will provide overpressure protection to subsea process pipelines.
DNV GL’s Manchester, UK office will carry out the project. The scope of work involves verification of the design, configuration, and architecture of the HIPPS logic solver, and associated interface equipment, to ensure it meets the requirements in the IEC 61511 standard.
The award of this work follows collaboration with GE Oil & Gas UK on the functional safety aspects of their new completion and workover riser system. The new service specification will also be used in ongoing projects involving BOPs for other clients.
DNV GL says it has observed an increase in the importance of functional safety and that functional safety is more frequently being applied in the offshore industries for ensuring the reliability of safety systems. The requirement for SIL certification for systems such as BOPs, workover systems, and pressure protection systems has become common place.
To respond to this, DNV GL has developed this service specification for functional safety certification, which can be applied to all electronic or programmable systems with safety functions. The service specification is a flexible tool that allows DNV GL to certify systems, subsystems, and components against a wide range of standards including IEC 61508, IEC 61511 and Norwegian Oil and Gas’ Guideline 070. The service specification also allows for the certification of development tools and management systems. DNV GL’s service specification for functional safety certification may involve the appraisal of entire systems, subsystems, tools and procedures.
On completion of the scope of work for the HIPPS certification project with GE, DNV GL will provide a certificate of conformity and a certification report.
