Piloting in Confined Spaces

When piloting in confined spaces, the gravest concerns are getting stuck or getting the tether snagged on an obstruction.

The best techniques are:

• Ballast the ROV as close to neutral as possible

• Proceed slowly and plan ahead before entering tight spaces

• Observe the entire immediate surroundings, including up and down, for any obstacles that might entrap the ROV or snag the tether

• Have someone feed tether as close to the entry point as possible

• Move slowly and deliberately to avoid stirring up silt

If the ROV or tether does get stuck, assess the situation as best as possible in order to avoid making the situation worse. See the section on Emergency Response to a Snagged Tether/ROV for additional tips.
