Offshore exploration and production of hydrocarbons have progressed into deeper waters, with several production systems operating in water depths exceeding 1,000 m.  The development and implementation of more rational and reliable hydrodynamic design procedures founded on detailed understanding and description of the physical processes are key objectives in the offshore work at DHI.

Loads and response of fixed and floating structures under combined impact of wind, waves and currents are studied in DHI’s 3D wave basin. This advanced facility is equipped with all necessary peripherals for running tests and analyses efficiently.

DHI has also developed reliable numerical models to describe the hydrodynamics, morphological processes and structural responses of subsea structures and pipelines.  Seabed variations around installations due to scour, sedimentation or migrating sand waves can be simulated by DHI’s dynamic numerical models.

DHI designs and assists in setting up complete monitoring systems, including sensors, data acquisition equipment, data analysis and storage software. Reliable monitoring systems have proven beneficial for both operational purposes and for improving the environmental design basis.
