In the past, DHI has been involved in several design and reassessments of fixed offshore structures, including both the establishment of environmental design data and the determination of the wave and current induced hydrodynamic loads.

Design data are established using DHI’s numerical hindcast models and field measurements. DHI has been involved in field mesaurements since the early eighties, and the experience in analysis of such data has lead to an in-depth understanding of the physics and statistics of waves.

The hydrodynamic loads on complex jacket structures have been assessed either through physical model tests or by the use of DHI’s hydrodynamic wave/current load generator.

During the past few years, the wave-induced loading of lower platform decks has become an important issue in structural integrity assessments for several operators. DHI has been heavily involved in this issues, to the extent that a numerical model for the computation of wave induced deck loads on offshore platforms has been developed.
