Testing of an electronics module
First Claim
1. 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.

Abstract
A method of testing an electronics module (11) for an underwater well installation, comprises the steps of: providing a test equipment (7) comprising a processor (8) and a Local Area Network (LAN) switch (9), such that the processor (8) may communicate with the switch (9); providing an electronics module (11) comprising a data acquisition means (12) and a second LAN switch (10), such that the data acquisition means (12) may communicate with the second switch (10); passing test data from the processor (8) to the data acquisition means (12) via the first and second LAN switches (9, 10); and monitoring the response of the electronics module (11) in response to the test data.

8. A testing system for a subsea electronics module (SEM) for use at a well installation, comprising:
-
test equipment comprising a plurality of processors for outputting test data to an SEM at a well installation and a first Local Area Network (LAN) switch, configured such that each of the plurality of processors communicate with the first LAN switch, the test equipment further configured to separately communicate packages of the test data from each of the plurality of processors, in parallel, to a data acquisition means of the SEM via the first LAN switch of the test equipment and a second LAN switch of the SEM to thereby reduce testing time, and to receive a response to the test data from the SEM to thereby evaluate operation of the SEM; and the SEM comprising the data acquisition means and the second LAN switch, the SEM configured such that the data acquisition means communicates with the second LAN switch to provide the test equipment a response to test data in response thereto to so that the test equipment evaluates operation of the SEM. - View Dependent Claims (12, 13)
