Structure ecosystem

In an era of low oil prices operators are facing increasing challenges to reduce CAPEX and OPEX costs. There is a need to design and build offshore structures that are more cost effective, while reducing operating costs of existing structures, without compromising structural integrity or safety in operation. A key to driving efficiency and reducing costs is the concept of a cloud-based digital twin, a virtual image of an asset and all associated data supporting asset-centric engineering applications. Updated throughout the lifecycle, the digital twin is an aggregated database representing the as-is state of the asset at any point in time.


DNV GL’s Structure ecosystem solutions cover the complete needs for strength assessment and structural integrity management from initial design to eventual decommissioning. Through the digital twin it supports long term information management and provides a cost-effective collaboration platform available to all stakeholders. With its advanced analytical offshore structural engineering tools, and access to data from anywhere at any time, our ecosystem helps to ensure more profitable, safe, and sustainable operations of all types of fixed and floating offshore structures, including those supporting offshore wind turbines.

Sesam Pipeline software
Pipeline design software

Pipeline design software

Based on many years of research and experience, we have developed special-purpose pipeline design software to make it easy for designers to document code compliance without the need to go to complex finite element analysis. In this way, extensive time and cost is saved for each project. Sesam's tool set contains a collection of six software modules to support offshore engineers to efficiently perform design analysis calculations on offshore pipelines.

Sesam Wind software
Engineering analysis of fixed and floating OWT structures

Engineering analysis of fixed and floating OWT structures

Sesam for offshore wind is a tailor-made solution for structural strength analysis of both fixed and floating offshore wind turbine structures. Accounting for the combined effect of wind on the turbine blades and hydrodynamic loads on te support structure, ultimate limit state (ULS) and fatigue analysis can be performed on the supporting structures, be they fixed (gravity based or piled to the sea-bed) or floating (moored/tethered) vessels.
