Wave Loads and Offshore

Calculating wave loads on floating or fixed structures can be challenging if the geometry or the conditions do not allow standard engineering calculation method to be used with confidence. 

Our CFD service can offer accurate wave loads on various types of structures ranging from sailing vessels to fixed coastal structures.

In the past a significant effort was devoted by our team in the field of wave modelling and offshore technology. Some of the problems we tackled are the listed below.

Wave Loads on Monopiles

Being the main structural element of any coastal or offshore structure, wave loads on monopiles present a very important problem in many ocean engineering fields. Read more on  related studies in some of the papers below:

Wave Loads on Offshore and Coastal structures

Offshore structures such as platforms or FPSOs are exposed to some of the worse weather conditions in the worlds. We can help you predict those extreme loads and make the project a bit safer. For coastal structures wave shoaling and breaking make them even more dangerous, and requires us to use compressible air models to tackle the problem. Here are some of the publications related to this problem:

Green Water Loads

Assessing green water loads on offshore structures or sailing vessels can be a challenging task given the complexity of the problem. This phenomenon has been a focus of our work for a long time and we are sure that we can help you out. Take a look at some of our publications on the topic:
