#5 – Communications

March 23, 2005

Mariners are reminded that the following communications procedures will be in effect at the structures:

AT LOCKS

Lock crews’ initial communication with vessel will occur when vessel is inbound at the L/A2

Vessel to acknowledge at minimum the following 3 positioning instructions:

  • Initial communication (final mooring position)
  • 25 m spotting instruction (15 m at SLSDC locks)
  • Final spotting instruction (In position)

At SLSDC locks for downbound maximum sized vessels required to winch to final mooring position the following additional communications must be acknowledged:

  • The message “15 m to the 15m mark”
  • The message “In position at the 15 m mark”,
  • When the vessel has winched into position, the message “In position”

AT BRIDGES (remote from locks)

The following procedure applies at all free-standing Bridges, namely:

  • Br. 7A/7B, SLU, VAL in the Montreal Lake Ontario Section
  • Br. 4, 5, 11 and 21 in the Welland Canal Section

The bridge operator will make a VHF radio call on the normal working channel to the last vessel through the bridge draw, immediately prior to initiating the bridge lowering / closing sequence. Vessel may respond if there is a problem.

e.g. “VESSEL NAME, BRIDGE 21 WILL START TO LOWER”
