A number of publications on modelling of wave-structure interaction using different methods and technologies have recently been published.
At the 27th International Conference on Offshore and Arctic Engineering held in Extoril, Portugal, 15-20 June 2008 DHI presented two new papers:
-
Numerical simulation of ship motion in offshore and harbour areas by Erik Damgaard, Bjarne Jensen, Simon Brandi Mortensen, Hans Fabricius Hansen and Jens Kirkegaard.
A method for simulating the motions and mooring forces of a moored ship subject to wave forcing has been further developed and validated for both the open water case and inside harbour areas. The simulation tool solves the equations of motions in the time domain. Examples from both open waters and enclosed waters in harbours are presented.

Numerical modelling of wave run-up on a wind turbine foundation by Anders Wedel Nielsen, Simon Brandi Mortensen, Vagner Jacobsen and Erik Damgaard Christensen.
The paper presents the results of a CFD model of the wave run-up on a mono-pile. The mono-pile is widely used as the foundation unit for offshore wind turbines. The aim for the calculations is to make a detailed investigation of the effect of three-dimensional (3D) waves on the run-up and to determine the maximum wave run-up. The CFD results are compared with the results of physical model tests conducted under the same conditions. The model tests were conducted under idealized conditions: The tests were carried out on a horizontal bottom using phase and directional focused waves to obtain a 3D effect and at the same time being able to control the breaking. The key objective of this part of the numerical analysis is to develop a model capable

The June 2008 issue of Offshore Center Denmark’s news magazine ON/OFF focus on offshore wind power. The magazine includes a DHI article entitling “Wave impact on offshore wind turbines and foundations”.

Scandinavian Oil-Gas Magazine No 5/6 2008 presents the article “Wave-in-deck loads on offshore structures” by Vagner Jacobsen and Bjarne Jensen.
This article focus on methods and technologies for re-assessment of design conditions for existing offshore structures, where the decrease of air gaps due to sea subsidence and the effect of climate changes (both sea level rise and storm intensity) is of increasing interests for the offshore oil & gas operators.
