Prove structural integrity during all stages in the lifetime of offshore bottom-fixed installations

We believe success relies on the ability to have continuous confidence in the compliance, safety and structural integrity of new and ageing structures.

Built on decades of engineering expertise, our software enables owners and engineers worldwide to improve the structural design, prove structural integrity during operation and document satisfactory residual structural strength for prolonged life in service of offshore wind and O&G installations.

DNV offers digital solutions for structural strength assessment of offshore installations covering the design tasks to efficiently optimise the design with respect to costs, feasibility and compliance with regulatory standards. Our tools and services provide you with the confidence and support needed for structural considerations during all lifetime phases of bottom-fixed installations including the operational phase and service life after permitted lifetime.
