The purpose of the on-line monitoring (OLM) system, which has an anticipated installation of Mid October 2005, is to measure motions of the East Espoir wellhead platform and verify the continuing integrity of the structure.
The OLM comprises accelerometers deployed on the platform to measure motions in the NS and EW directions.
In addition, a WaveRadar is included in the system to evaluate wave height/displacement relationships.
The OLM System can be used for:
Data from the sensors is recorded and analyzed by a computer system to determine the natural frequencies of the platform. A change in a natural frequency can indicate member severance or a weakening of the foundation.
As the equipment will be operated in a marine, tropical climate, it has been designed to operate with an air temperature of up to 45 degrees Celsius.
The award of this new contract marks the continuation of the long-term relationship built with CNR in the North Sea where monitoring systems are operated on the Ninian South and Murchison platforms.
