Pile Driving Monitoring (PDM) during driving and Pile Dynamic Testing (PDT) are widely used in onshore and offshore construction to ensure the structural integrity of the piles during driving and achieve a safe and economical pile installation. PDM helps to assess the pile behaviour during installation and thus to confirm the assumptions taken during pile design; as well, it allows to control the dynamic stresses in the pile and keep the hammer energy at max level compatible with pile integrity, thus allowing for an efficient management of the piling on field.

Since the 1850s, submarine cables have played an integral role in international data transmission and are now crucial to the growth of the offshore renewable sector. It is imperative to ensure the adequate protection of submarine cables so that they remain safe from threats such as fishing gear, shipping anchors, dredging and other dropped objects for the lifetime of the asset. 

Cathie will be presenting Cable Burial Risk Assessment methods and the current state of play at the International Offshore Partnering Forum (IPF) 2018 in Princeton, New Jersey.

Following the news of the completion of the installation of the 60 monopiles and transition pieces at E.ON’s Arkona Becken Südost windfarm project ahead of schedule, Cathie now inform that they have performed a study which enabled the reduction of noise in the water column created by monopile driving.

According to a recent report by Wind Europe, offshore wind in Europe doubled in capacity in 2017 to 3,148 MW raising Europe’s total installed offshore wind capacity to 15,780MW. There are now 92 offshore wind farms in 11 European countries, and once 11 offshore projects under construction are completed, the total installed grid connected capacity will increase to 18.7GW.

As the possibilities and uses of piled offshore foundations increase, so do the environmental, financial and technological challenges and demands. Leading providers of offshore geo-intelligence, foundation design and installation give us their take on the most cost- and time-efficient methods to overcome challenges

Leading offshore geoscience and geotechnical engineering consultancy, Cathie, are pleased to announce the opening of operations in the USA with the appointment of a Vice President. The move is part of the company’s drive for international expansion and will enable them to better serve the US offshore energy industry, following creation of Cathie Inc., at the turn of the year.

As one of the only industry contributions to the highly regarded Canadian Geotechnical Journal, a paper cowritten by Cathie enables more cost-effective pipeline protection solutions, by avoiding overly conservative burial depths. The publication is part of a special issue on pipeline geotechnics, one of Cathie’s special areas of expertise.

The Carbon Trust’s Cable Burial Risk Assessment (CBRA) guidelines, coauthored by Cathie, have now been used as far afield as the CERES Project in Australia. In addition to the now commonplace use of CBRA guidelines for offshore renewables and HVDC interconnectors, this represents a significant step forward in the acceptance of CBRA as best practise in the subsea power cables sector.

Global leader in offshore wind DONG Energy Wind Power has selected Cathie, Ceteal and Ghenova to provide support for its offshore wind farm projects over the next five years.
