Development of new models for shipping and naval industry for the prediction of rogue waves

Project partner:

Stad Towing Tank, Postboks 244, 6701 Måløy.

Project duration: 2016 -

Project description:

Rogue waves represent one of the least studied phenomena in the naval and marine transport sector, and denotes the occurrence of 3-storey building sized waves during strong low-pressure systems in oceanic environments. Rogue waves were documented for the first time in 1995 on the Draupner rig in the North sea, where an unexpected 27 meter high wave was read by the laser-detector on the rig-base. In times of climate change and strong weather storms at oil-installation environments, it is critical to predict the occurrence of rogue waves, particularly in relation with safety off-shore. Rogue waves are also an interesting phenomena at the mathematical level, as they include central parts from quantum mechanics (wave packets). This project aims to deliver a mathematical model to predict rogue waves for the maritime and off-shore sectors as well as the insurance sector and is developed through the use of supercomputers and advanced mathematical software.
