The OFFshore ITRH united a world-class team of researchers across the full spectrum of offshore engineering – from the atmosphere down to the seabed – providing a new multi-disciplinary perspective. These researchers were drawn from the following diverse areas: metocean (meteorology and oceanography), hydrodynamics, geotechnics, statistics, reliability, marine structures and asset management. This breadth provided a balanced perspective on performance in design and operation. Work in the OFFshore ITRH was separated into the following five key project streams.

Project One: Metocean hazards from solitons

Seawater temp

The original aim of this project was to quantify the soliton hazard in the North West Shelf by using field observations to evaluate a detailed numerical model which allowed for better prediction of total design current at any location in the study area.

Project Two: Wave-structure interaction


The original aim of this project was to use world-best numerical modelling capabilities to enable reliability-based analysis of complex wave-structure interactions and hence improve the efficient operation of floating facilities.

Project Three: Reliable moorings and risers

P3a thumb

The original aim of this project was to develop new design tools which are able to reduce design uncertainty to a point where both high-capacity steel catenary risers are viable and anchored mooring lines are reliable.

Project Four: Novel anchors and subsea foundation systems


The original aim of this project was to develop low-cost low-risk subsea anchors and foundation solutions which benefit from the consideration of whole-life behaviour.

Project Five: Floating facility data analytics for condition/ longevity monitoring


The original aim of this project was to envelope the other projects and apply engineering statistics and modern data analytics to enhance facility whole-life performance.
