Patent ID: 8290737

Claim:
A method of testing a subsea electronics module (SEM) for an underwater well installation, comprising the steps of: providing test equipment configured for testing an SEM, the test equipment comprising a plurality of processors and a first Local Area Network (LAN) switch, such that the processors may communicate with the first LAN switch; providing an SEM for an underwater well installation, the SEM comprising a data acquisition means and a second LAN switch, such that the data acquisition means may communicate with the second switch; separately passing packages of test data from each of the processors of the test equipment, in parallel, to the data acquisition means of the SEM undergoing testing via the first and second LAN switches to thereby reduce testing time, performed separately from normal operations of the SEM in the underwater well installation; and monitoring for a corresponding response of the SEM in response to the test data passed to the SEM, the monitoring performed by the test equipment to evaluate operation of the SEM.
