Can you describe the challenging water conditions that Crabster had to navigate? For example, how fast were the currents you had to deal with? How deep was the water? How was the visibility underwater?

The water depth was about 45 meters, visibility was less than 20 centimeters and water temperature was 11~12 degrees C. The maximum current is more than 8 knots at the area but when we were there, the tidal current was less than 3 knots. Sometimes tough wave and wind bother us. The Crabster had no problem to work in those conditions, but Crabster cannot overcome its mother ship. Our ship was too small to keep her position in those current, wind and wave conditions. So we wanted to attach our ship to the large rescue barge firmly moored with four anchors. But we could not have permission.
