Lecture by Professor Alistair B A Boxall (University of York).

The replacement of offshore pedestal crane slew bearings has been carried out for over 40 years however the vast majority being carried out on fixed installations. The presentation will detail how this activity was carried out onboard an FPSO whilst still on station in the UKCS where not just complexities of lifting a crane but vessel motion being the major factor which needed to be thoroughly engineered to achieve successful execution.

Over the next 10 years there will be a substantial number of assets that need to be removed from the North Sea and operators will be looking hard at ways to reduce cost given that this area does not add production. This presentation will cover: Why the decommissioning industry is so important to the North Sea The various approaches to decommissioning Case Study Key Safety Issues to think about for different stages of decommissioning projects UK legislative influences Environmental aspects…

Claxton partnering with the National Decommissioning Centre, the University of Aberdeen and the Net Zero Technology Centre, have been developing an underwater laser cutting solution. This involves interfacing a 15kW industrial laser system to a custom designed subsea laser cutting head with associated intelligent control and monitoring system with electronic motion control. This will offer a feasible alternative to conventional cutting methods, bringing a low-carbon, quick and clean underwater cutting technology to the decommissioning market. This lecture will outline the…
