We completed the prototype subsea sensor system earlier this year and in-air testing for SAMIR (Semi-Autonomous Mooring Inspection Robot) is well underway! The test bed is set up with samples to test data collection and deployment. SAMIR will be mounted onto and travel along the test pieces, collecting data as it goes. Once post-processed, the data will allow us to quantitatively evaluate the condition of the test pieces and demonstrate SAMIR’s capability.
We started by introducing a small surface defect (~2 mm2 in cross section, 10 mm long) into the sensor head and it was picked up very easily. The sensor head is expected to be capable of accurately measuring the metallic cross sectional area as well as locating and sizing defects in the outer layers of wire ropes, where most wire damage is known to occur. Wire core defects may also be detectable –continued testing will allow us to nail down the specifics.
In the coming weeks we will be conducting in-air, as well as in-water, testing on the prototype system on several different types of defects. We will also be testing the subsea deployment systems in preparation for offshore trials and operation. Keep your eye on this blog for the latest on this exciting new technology!
