Objective
The aim of the project is to obtain full scale data on the behaviour of the foundation of an offshore oil production platform.
The instrumentation system performed well. All accelerometers, structural strain gauges and mudmat pressure sensors functioned satisfactorily. The novel pile instrumentation also performed well. The project has determined the actual loads imposed on the piling and mudmats by the structural and environmental forces. In particular:
1. The environmental load acting on the pile group has been measured in environmental conditions up to a maximum wave height of 21 m.
2. The proportion of the environmental load carried by the mudmat and piles has been measured.
3. The distribution of load within the pile group and along the length of a pile has been determined.
4. The actual pile behaviour has been compared with design predictions.
5. The effective stiffness of the pile group has been measured.
British Petroleum Development Ltd have installed a production platform in 186 m of water at Magnus field in block 211-12 of the UK sector. North Sea.
The project consists in instrumenting the lower section of one of the four legs of the Magnus platform and piles supporting that leg. The behaviour of the instrumented members is recorded and a comparison made between measured pile loads and those calculated by conventional methods.
