12. Use the crane to slide the profiler down the cable and into the water. When the
MMP is sufficiently immersed to avoid unnecessary snap loads, release it and
recover the crane and tag lines.
13. Continue to stream cable, attaching the lower bumper at the planned location.
Secure the end of the cable to the acoustic release and anchor.
14. Deploy the anchor when the station is reached.
Recovery Procedure
To recover the MMP, complete the following steps:
1. Trigger the release and capture one end of the mooring.
2. Detach the float and run the cable through the A-frame block and onto the winch.
When the upper bumper is reached, pull that section of cable onto the deck and
remove the bumper.
3. Continue to wind cable onto the winch. The MMP will be on the tether
somewhere between the stoppers. The exact location of the MMP depends on the
profiling schedule, ballasting accuracy, and whether the tension in the cable after
release can sustain some degree of coupling with the drive wheel. The presence
of flotation modules below the lower stopper may have a strong effect on
coupling. However, the MMP is not buoyant in air and the drive wheel, even
with strong coupling, will only sustain a few pounds.
4. Continue to wind the mooring cable onto the winch and, in the absence of severe
fouling or entanglement, the MMP must eventually fetch up against the bottom
stopper. The stopper will sustain the full flooded weight of the MMP and can be
used to lift the profiler clear of the water. If you recover the bottom of the
mooring first, the top stopper can be used to lift the MMP.
