2-28. ANCHORING A RIBBON BRIDGE .

NOTE

Anchoring a Ribbon Bridge will require one boat for each 3 bays of bridge and not

less than one boat operator and two assistant boat operators per boat.

Boat operator. Maneuver the boat into position until the pushknees are in contact with the downstream bow ponton

of the bridge.

NOTE

When more than one boat is required, boats should be evenly spaced along the

bridge.

WARNING

Hold on to safety rails. You could be thrown overboard when the boat bumps the

bay.

Assistant boat operators. Wait on or near the bow of the boat without blocking the boat operator's view until the

pushknees touch the bridge.

Boat operator. Keep the pushknees of the boat in constant contact with the bridge.

WARNING

Do not get any part of body between bay and boat. Injury to personnel could

result.

WARNING

Make sure that each tieline is tight and the bay is held firmly against the

pushknees or the bridge will tend to pull off to the side of the boat.

Assistant boat operators. Secure one tieline to the nearest bow ponton anchoring pin on the bridge to port and

starboard of the boat. Pull each tieline tight and secure it to the bow bollard on its respective side of the boat.

Boat operator. Maintain bridge on centerline by adjusting the scoop controls and throttles. Follow directions of the

bridge commander.
