Private Bauxite Terminal at Porto Trombetas


The Porto Trombetas bauxite terminal is located in the Brazilian Amazon region, on the right bank of the Trombetas River, a tributary on the left bank of the Amazon Rivers. The terminal’s position is:

Latitude: 01º 27,6’ S

Longitude: 56º 22,8’ W


Access to the Trombetas River is through the Amazon River, entering through the North Bar near Lightfloat Amazon Nº 1’ Lat. 01º 34,1 N and Long. 49º 01.3 W.

Nautical charts:

The entire waterway, from the North Bar until Porto Trombetas, for about 575 nautical miles, is charted and marked with nautical river signaling. The Brazilian nautical charts for this stretch are:

  • 40, 200, 201 and 210, approach and passage at North Bar;
  • 202, 203, 204, 205 and 220, navigation on the Amazon River until Fazendinha;
  • 4101AB, 4102A/B, 4103A/B and 4104A for navigation on the Amazon River;
  • 4411;4412;4413;4414;4415;4416;4417;4418 for navigation on the Trombetas River.

Information for Ships released by the Hydrography and Navigation Authority keeps the charts updated with regard to changes in river signaling and depth.


Navigation on the Amazon and Trombetas Rivers requires constant attention; one must have the appropriate nautical charts, GPS, radar, ecobathymeter and AIS in good conditions.

During the day the coastal region of the North Bar may be covered by fog or smoke, making visual marking for the beacons difficult; at night the radio beacon signal may have a deviation of up to 10º.

Although the river bottom capacity for holding an anchor is good along the entire waterway, ship captains should pay attention on the North Bar stretch, where mud suction of the anchor may occur.

Piloting services:

These are required from Macapá (Fazendinha) to Porto Trombetas, with two pilots aboard. The pilots remain in service during the entire loading period.

Piloting at the North Bar is not obligatory and depends upon the decision of the captain, and may be obtained through the navigation services with a large routing detour to pick up the pilots at Salinópolis.


Along the entire waterway it is currently 38 feet (11.58 meters) deep in freshwater, with shallow depth restrictions during the high tides at the North Bar.

During the dry periods of the Trombetas River (September to December), there may be a reduction in the loading draft because of the river level. The river level and draft are monitored by MRN and informed daily to the Santarém Port Authority.


Tides are significant at the North Bar of the Amazon River and should be calculated according to the information found in nautical chart 210 and the Route Map. The current follows a SW direction during high tides and flows NE during low tides, with a speed of up to 3 knots during neap tides and 5 knots during spring tides.

There is no tide on the Trombetas River, where the current flows downstream at a velocity that varies from 0.5 knots during dry periods to 1.5 knots during the high water period (April to August), and may reach 2 knots close to its mouth.


Because of the restrictions imposed by the curves on the Trombetas River, ships are limited to Panamax type with up to 260m LOA. During high water periods, from April to August, bulk-carrier ships with up to 40m Breadth and 260m LOA may be received, after consulting with MRN.


At Porto Trombetas there are two tugboats available, totaling 62 tons of bollard pull and two launches to receive spotters during docking and mooring and unmooring maneuvers for ships.


Since Brazil is a signatory of the International Convention for the Prevention of Pollution from Ships, the Captains and Ship-owners must follow all of the norms in MARPOL 73/78 and CLC/69, as well as determinations by the Brazilian government.

Discharge of any type of ballast except for clean freshwater is forbidden, as is the dumping of rubbish or any other waste along the waterway. Violations are subject to severe punishment. The terminal does not have equipment for removing ballast of any type, nor of oily residues from washing tanks or rubbish collection.


Discharge of saltwater into the Trombetas River is forbidden and is subject to heavy fines. Accord to the Maritime Authority rule Normam 20, the exchange of water must be done in two stages. The first must be at least 200 nautical miles from the coast in waters with at least 200 meters of depth, of port departure ballast for ocean saltwater. The second stage is the exchange of saltwater, beginning at the entry to the North Bar, at the 20 meter isobath, until docking at Fazendinha, for freshwater. After pilots have been received, the discharge of saltwater is not permitted.

Procedures for arrival:

Ships coming from the high seas must send the ETA North Bar 72 and 48 hours before arrival, addressed to the Agent and MRN, for dispatch, requests for pilots and sending of information on river signaling at the North Bar and restrictions on navigation along the Amazon and Trombetas Rivers. The shipping agency will inform the necessary documents to be shown by the Captain to the Brazilian authorities.

Immigration, Customs and Sanitation inspections are done in the Fazendinha docking area, and customs inspection may also be done at Porto Trombetas. Bulk-carrier ships with more than 18 years of age may be inspected by representatives of the State Port Control to verify their state of conservation.

After receiving “Free Circulation” from the Agent, the Captain must inform the ETA at the mouth of the Trombetas River to the Agency and MRN, and must obtain authorization to enter this river. Instructions regarding mooring or waiting buoys are sent with this authorization.

Anchorage points:

For inspections by authorities and receiving pilots, at Fazendinha: Lat 00º03.7’ S and Long 51º05.8’ W

Awaiting authorization to enter the Trombetas River: Lat 01º54,5’ S and Long 55º36,0’ W

To await mooring on the Trombetas River, on the docking buoys at waiting points 1 and 2

For ships under quarantine or repairs, buoy nº 03 and ships awaiting improvement in weather, anchorage area at about 0.7 miles upstream from the ore pier.

Safety (ISPS Code):

The Porto Trombetas terminal has its safety plan set up according to the norms of the ISPS Code of the IMO. Before mooring the ship safety officer must contact the terminal safety supervisor to receive information on port inspection for loading and unloading crew, passengers, food or any other type of material. This contact can be done via VHF (channel 14) or by telephone 55 93 3549-7415.

Loading Terminal:

The pier is a steel structure with a length of 120m, with six concrete dolphins and four docking buoys, which can receive only one ship at a time. The pier is protected by permanent fendering.

The ship loader moves horizontally and vertically to both sides of the pier. The terminal operates 24 hours a day, including Saturdays, Sundays and holidays, and may be contacted by VHF on channel 14. The loading rate may reach 85 thousand metric tons/day for dry and wet bauxite.

Loading Parameters:

River freshwater density (average): 0.996

Angle of repose in the hold pile: 34º

Specific weight of bauxite: 1.4 to 1.7 ton/m³.

Aerial Draft:

The distance from the ship waterline to the mouth of the loader is around 13.5 m during high water and around 19 m at low water. Captains should ask the ship Agency for information on the level of the Trombetas River, in order to carry out deballasting before mooring at Porto Trombetas.

Facilities at the Terminal:

  • Emergency medical service may be found at the Pro Saúde hospital through the agency representing the ship;
  • Mail and public telephone are available to local and international communications;
  • Small emergency repairs may be done at the MRN workshops. Requests are made through the shipping agency;
  • There is freshwater available for supplying the ship, after consulting Mineração Rio do Norte;
  • The ship crew may visit the public area of the port, taking care to take their documents with photographic identification;
  • There are daily domestic flights to Manaus, Santarém and Belém;
  • Oil and electricity supply from land is not available;
  • There is no rubbish collection for the ships.
