a. Except as specified below, vessels arriving at Panama Canal (ACP) waters shall switch
their main propulsion engines, boilers, auxiliary generator engines, and other ancillary
equipment from residual fuels to marine distillate fuels. Changeover must be completed
according to the following:
1. Southbound vessels, at least eight nautical miles from the Breakwater on the Atlantic
side.
2. Northbound vessels, at least three nautical miles from the Sea Buoy at the Pacific
Entrance.
b. Vessels shall record the fuel changeover in their Engine Room Logbook and/or Fuel Oil
Changeover Record Book. The record book entries shall specify the date and time of
commencement and ending of the changeover from marine residual fuel to marine
distillate fuel.
c. After completion of any changeover to marine distillate fuel, the vessel shall verify that
the main propulsion engine operates properly. If necessary, the vessel shall undertake
appropriate corrective actions to ensure the vessel’s safe and expeditious transit of the
Panama Canal.
d. Vessels may supplement or replace marine distillate fuels with any of the following:
1. LNG fuel (including boil-off gas)
2. Biofuels compliant with MARPOL Annex VI
3. Residual marine fuels with maximum sulfur concentration of 0.5% and not exceeding
a viscosity of 70 centistokes @ 50°C.
4. A closed loop scrubber in zero discharge mode or a hybrid scrubber in closed loop
and zero discharge mode
e. The type of fuel and scrubber combination intended for use in Panama Canal waters
must be uploaded by the vessel’s local agent to the FUEL DECLARATION menu in
VUMPA for all vessels arriving to Panama Canal waters. In turn, this information will be
verified on the BDN or corresponding fuel analysis report by Panama Canal Boarding
Officers upon the vessel's arrival to Canal waters. Additionally, vessels with approved
scrubbers, must have the following information readily available for verification: IAPP
Certificate and Supplement thereof, total volume of effluent holding tanks, and logbook
entries confirming that effluent holding tanks were emptied prior to arriving to Canal
waters.
