Background

The central question in the CresT JIP was: What is the highest (most critical) wave crest that will be encountered by my platform in its lifetime? This resulted in a number of important and practical recommendations for the wave heights and crest heights to be used in (floating) platform design. One of the general conclusions was that the properties of short-crested waves are very different from the long-crested waves, which are typically used for the design of offshore structures. 

Objective

As there is no state of the art methodology to apply short-crested models instead, in ShorTCresT, the same group of partners proposes to take into account short-crestedness in the design of offshore structures against extreme waves based on a good description of their spectral characteristics, statistics, kinematics and loading.
