The offshore industry has recognized the need for lighter and more cost-effective solutions for deepwater field development and for deepwater drilling. One of the critical points are the pillars that keep the oil platform fixed to the sea bed. Recent developments by Kvaerner Oilfield Products make use of composite materials instead of stainless steel materials.
FOS&S has been involved in this project for the characterisation of the mechanical behaviour of these composite pillars of oil platforms. The objective was to measure the strain behaviour on a lab scale prototype under different load conditions. In order to measure the mechanical deformation under different load conditions, Fibre Bragg Grating sensors have been embedded inside the composite rods during the production of these rods. After production of the sensor integrated lab scale prototype, load testing has been performed.
