PERFORMANCE MONITOR FOR SUBSEA EQUIPMENT
First Claim
1. A system for monitoring subsea equipment performance and for providing early warning for equipment maintenance, comprising:
- at least one sensor coupled to said equipment and arranged to measure at least one performance indicator value; and
a calculation unit for sampling the measured indicator values at a chosen rate and from the sampled data estimating a likely future development of the sampled value and estimating the time for the passing of a chosen threshold value, the threshold value being a critical value requiring repair or replacements of said equipment, the system being adapted to provide a signal indicating the calculated time of repair/replacement, and wherein the monitored equipment is a subsea pump in a subsea pumping system and one of said at least one performance indicator values is the lube oil consumption.
