Jan 18: RAN reparation

Li Ling – Jan 18:

RAN reparation today!

After the test mission last Saturday, Anders and Mark noticed that the downward looking multibeam on RAN was… Hmm… Not entirely attached to RAN… Lucky that they caught the issue! If we would have deployed without checking carefully, the multibeam will probably not be working and could, in the worst case… fall off into the ocean 😱

Doing the actual inspection and reparation was actually quite an operation for everyone onboard. Normally, RAN sits in her LARS (Launch And Recovery System) up-right, and we can’t access the downward looking multibeam… Anna and Mark and Anders tried covering the entire LARS in grease the other day, hoping that the grease will lubricate the LARS enough so that we could roll RAN around. Unfortunately, a 2 ton vehicle was not easily rolled… So, in order to access the multibeam, we had to lift RAN from the container to the heli deck (2 floors up) with a crane.

Luckily, the actual reparation turned out to be quite easy, it seemed like only two M6 bolts were missing. Getting RAN in and out of the container, however, was quite a bit of work with many people involved!

After the reparation, RAN was craned from the heli-deck down into the ocean, and then a normal recovery procedure was performed to get her back into the container.
