Were there any difficulties in the mothership putting Crabster into the water with its crane and retrieving Crabster from the water? And did Crabster walk and operate well underwater?

We used our own LARS(launch and recovery system) consisting of crane and cable winch. It was the first use of our LARS designed for Crabster. The LARS worked well. During the weather was good, we have no problem with mothership and all the launch and recovery process was done perfectly. But the ship was too small to work in wavy and windy weather. The ship’s roll motion was too big to launch and retrieve the 700kg-Crabster safely. Crabster walked seabed while taking seafloor images with acoustic camera. Crabster was launched 13 times and stayed in water total 15 hours 36 minutes and worked total 11 hours 21 minutes on seafloor while Crabster remained in Jindo for 20 days.
