comments: Picked up and made up ARC, Powerpulse, Sonicvison, NMDC and NMDC pony. 

Meanwhile lined up for testing CRI hose and perform injection test. Observed that CRI hose had detached from subsea wellhead. Valve on hose and check valve was dug in the mud/seabed. Attempted to grab valve assembly but could not apply enough force with ROV.
