A key challenge for the future is to leverage new technologies for cost-efficient development and operation, while maintaining or improving safety and production availability. </p><p>DNV’s history in subsea technology goes back to the early 1970s, and is evidenced by completed projects, significant research, published standards, and recommended practices. By working with key suppliers and operators worldwide we have gained a unique cross-industry understanding of the complexities of subsea tie-backs, specific systems, equipment and components, degradation mechanisms, and integrity. DNV has run several joint industry projects (JIP’s) to address subsea challenges.  </p><p>Globally, our experts support customers with drilling and well, subsea production systems, subsea power and processing systems, umbilicals, cables and risers.  </p><p>By combining this experience with our deep expertise in flow assurance and materials, we help asset owners and suppliers address challenges in design and operation. These can include: </p><ul><li>Barrier philosophy and integrity </li><li>Design analysis and verification</li><li>Functional assessment </li><li>Pressure containment and structural strength </li><li>Material selection and compatibility </li><li>Operational loads and fatigue </li><li>Structural reliability analysis for remaining fatigue life </li><li>System architecture, reliability and operational safety </li><li>Lifting, marine operations, and intervention.</li></ul><p>DNV can assist with:</p><h3>Concept and feasibility  </h3><ul><li>Concept selection and FEED to
