OSLO, Norway — Ocyan has engaged DNV as an independent third party for the qualification process concerning a system for injecting hydrogen as an additive in the internal combustion engines of drilling rigs.
The aim is to reduce diesel consumption and greenhouse-gas emissions from drilling.
DNV will ensure the technology reaches the anticipated maturity, following provisions in DNV-RP-A203. This provides a systematic approach to technology qualification and is said to ensure that new technologies function reliably within specified limits.
DNV’s three-pronged approach covers the technology’s qualification process (demonstrating the performance and reliability of the system); assessment of operational risks (with a focus on the safety of the new system and of the drilling rig); and an assessment of Class requirements (evaluating the requirements of the Classification Society for the issuance of Approval in Principle for the system).
Ocyan is working in cooperation with LZ Energia, which develops solutions for reducing fuel consumption and air pollution in its clients’ operations. Shell Brasil is supporting the project, via the RD&I investment clause of Brazil’s National Petroleum Agency.
“Our cross-disciplinary approach ensures that all technological, safety and regulatory aspects are fulfilled prior to deploying the technology, providing transparency and trust for the different stakeholder,” said Alex Imperial, vice president of DNV's Energy Systems, South America.
Leandro Brandão, new business manager with Ocyan, added, “Starting from a pilot concept that LZ uses in engines for the road segment (trucks), we are adapting it for use in large engines of our rigs. By using hydrogen together with diesel, optimizing combustion, the differential of the proposal is saving fuel and emitting less pollutants.
“After carrying out a pilot test on one of our rigs earlier this year to validate the concept, we are still in the first phase of the project, which includes the delivery of the functional prototype of the product. Having overcome all the challenges of this phase, in the future, we intend to continue with a second stage, whose efforts will be based on tests in a relevant environment and the commercialization of the product.”
