The cities of Quequén and Necochea constitute an urban conglomerate of about 86.000 inhabitants divided by the Quequén Grande river. There is an intense commercial activity as the city is in the middle of one of the richest farming areas in the country. There are also important agro-industrial plants (vegetable oil and seeds by-products) and fish processing plants. Also, there is a médium-sized agriculture equipment industry. The area has good road access and is connected by highways Nº 55, 86, 88, 227 and 228. The city is served by the Ferrosur Roca railway and there is a small airport for medium sized airplanes working domestic routes.

Port general description:

The port is situated at the mouth of the river Quequén, Necochea occupying the right bank and Quequén the left bank. In 2011, 283 ocean going vessels called. Trade consists mainly of exports of soybeans, wheat (mainly to Brazil), maize, sunflower seed pellets and vegetable oil. A total of 5,6 million ton of grain and agri by-products were exported in 2011. Shipments of wood chips have dropped due to the local wood¥chip plant is presently not operating. Imports are almost entirely confined to the reception of bulk.


There is an anteport immediately inside the breakwaters and there are 13 berths along the riverfront (seven on the Quequén side and six on the Necochea). The least width in the anteport is approximately 500 m; anchoring is not allowed. On entering, and weather permitting, vessels are swung in the anteport to enable them to berth bow out ready for sailing. Should this not be possible vessels berth bow in with the need to be swung on completion of loading and the possibility of delay depending on weather conditions. The anteport is affected by some swell, as are all the berths in the port especially during southerly gales.

Port and Berth Description:

The port has two protecting breakwaters, the northern breakwater measuring 572 m and the southern breakwater to 1594 m, providing protection from the southern swell. The entrance between breakwaters is 220 meters wide and the channel is dredged to average depth of 13,70 m (45 ft) (July 2012) in a width of 120 m. It is proposed in the near future to shorten the northern breakwater by 50 m.


Quequén/Necochea has an open roadstead delimited as follows:
North: by an imaginary line running parallel to coast. Distance 5 miles.
South: by parallel 38º 46´W
West: by meridian 58º 51´W
East: by meridian 58º 21´W Pilot boards about 1,5 miles SE of southern breakwater.


Anchoring is permitted within the zone delimited by the following limits; North: by an imaginary line parallel to the coast 5 miles off the coastline; South: by parallel 38º 46´ S; West: by meridian 058º 51´ W and East:by meridian 058º 28´ W. However the Coastguard may allow anchoring within the 5 mile limit in the case of having to embark/disembark crewmembers, etc. The PNA regularly broadcast gale warnings in Spanish.

Restrictions (As per Disp. PNA QUEQ, RB6 Nº 246/06 and 199/07):

1) Maximum permitted LOA to enter/leave port 230 m, basis channel width of 120 m. Should channel width be reduced for any reason then maximum permitted LOA is decreased by 10 m for every 5 m reduction.
2) Whilst there is no maximum stipulated draft at this port, the recommended maximum is 13,00 m (43 ft) and this is the maximum recorded draft to date.
3) Regarding draft/wave height: If wave height, measured on the outer part of the access channel, is equal or less than 0,50 m, all vessels sailing/entering must leave under the keel clearance (UKC) of 0,3 m (1 ft) if rising tide, or 0,6 m (2 ft) if ebbing tide. Additionally to this UKC, for LOA from 80 m to 230 m, ships sailing/entering must add a safety margin of 0,10 m per each 0,10 m of wave height exceeding 0,50 m, up to a wave height of 1,80 m. For wave height above 1,80 to 2,70 m the safety margin to be applied to the UKC depends on draft, beam and LOA, with different percentages related to ship´s draft for vessels entering, and other percentages for vessels sailing, providing the waves’ period is up to eight seconds for all cases. Agents must be specially consulted about these three safety margins.
4) Coastguard prevents ships from entering or leaving port if: a) wave height exceeds 2,40 m (ships up to 230 m LOA) or 2,70 m (ships up to 140 m LOA); b) wind velocity exceeds 37 km/h-20 knots; c) when visibility is less than (2) two nautical miles.
5) Crossing is not permitted in the access channel, nor are maneuvers inside the port when another vessel is entering/departing.
6) Vessels are normally required to berth bow out, however they are permitted to berth bow in if conditions do not permit vessels to be swung or if special cargo conditions so require.
7) For vessels entering/leaving trimmed by the stern, the unsighted distance forward of the bow shall not exceed 400 m.
8) For entering/sailing vessels may have a positive squat of not more than 2%. Additionally, masters are warned that a high tension electrical cable is strung above the river between berths 6 and 8. Height is 40 m (131 ft) at datum. A system for wave height and direction recording is in service, located at Lat 38º 35’37,2´´S , Long 58º 41′ 20,4″W , depth of 14 m (46 ft) at 630 m from south breakwater, not interfering with traffic.

Berth assignment:

Agents should notify Consorcio de Gestión del Puerto de Quequén (Port Administration) harbor master and grain elevator / shippers at least two working days beforehand of vessel´s ETA with confirmation holds ready. It should be noted that vessels loading vegetable oil have priority at berth 1 and any other vessel requesting this berth, in theory, must be prepared to accept vegetable oil loaders second off if need be. Regulations state combined beams both vessels plus fenders must not exceed 50 m. However, usual practice dictates that the vessel on the berth is requested to work a minimum of 18 hours per day to ensure prompt termination and freeing of the berth.

Local communications:

Radio communications 24 hours a day via Argentina Radio. Quequén Prefectura Naval Radio, L5B and VHF Ch# 12-14-16. Also VHF for Pilots and launches.


Compulsory. Pilots offer their services individually or in association with others. Pilots board about 1,5 miles SE of southern breakwater head.

Free pratique:

granted only alongside, not at anchor.


Use of two tugs for entrance and departure is compulsory, with the following exceptions:
1) Vessels up to LOA 80 m – no tugs required.
2) Vessels of LOA over 80 m up to 100 m – one tug required.
3) Vessels of LOA up to 140 m berthed bow out can sail with one tug except from berths 7, 8, 9 and 10. (With special coastguard permission).
4) Vessels of LOA up to 160 m with bow thruster of adequate HP and immersion can enter/sail with one tug except to/from berths 7, 8, 9 and 10. (With special coastguard permission). A tolerance of 5% on the above figures is normally granted by PNA. Two towing companies operate with two tugs each, all of about 3500 HP.
