DNV GL has been involved in verification of maintenance activities on critical subsea well equipment for many years. In 2017 a new revision of our Recommended Practice DNVGL-RP-E101 was issued, based on continuous interaction with market partners that supported a revision of this service document. The purpose of the revision was to harmonize different RPs addressing the same topic and make the document applicable globally, but most importantly to reflect the changes in the market.
DNV GL see that the drop in oil price has led to new business models within subsea maintenance with significantly lower volume and cost levels. We also see that the non-OEM side of the market has grown. The balancing act is now to keep a quality control level that secures technical integrity, and at the same time demonstrate an acceptable service cost.
The revised DNVGL-RP-E101 underlines the benefits of a risk based or condition based approach in terms of scoping only the critical components and processes for verification.
With the revised document DNV GL as an independent party has taken the market changes into account and facilitated for the new business models, in order for all players to succeed with the goal of having safe and operational well control equipment.
