Trollhatte Canal (SETHN)

The canal, operated by the Swedish Maritime Administration, is 82km long (10km of which are man-made), the remainder being a natural waterway - The Gota Alv River. The difference in level between Lake Vanern and the sea is 44.0m. This change is catered for by six locks: one in Lilla Edet of 6.0m, four at Trollhattan of 32.0m (total) and one at Krinkebergskulle of 6.0m. Double bottoms in the locks ensure an even distribution of the water. This makes for gentle water movement, during both filling and draining with 8,000 - 12,000mі of water required for each lock operation. Minimum water depth in the main canal is 6.3m and the threshold depth of the locks is 5.7m MLLW. The locks in which vessels pass through are equipped with electrical/mechanical doors and gates. The water distributes evenly throughout the locks due to the double bottoms and means that water is calm during both filling and emptying. The canal is an important route for merchant vessels and as a result they are able to navigate the canal 24hrs a day throughout the year. Discussions are taking place in order to ensure the future shipping on lake Vanern by building new navigational locks in Lilla Edet, Trolhattan and Vanersborg. The plan is that between 2026-2032 new modern locks will be built throughout Trollhatte Canal. The following port areas are on the Trollhatte Canal: Agnesberg, Surte, Nol, Lodose and Vanersborg (see separate port entries).

Trollhatte Canal connects the Gota River to Lake Vanern between Gothenburg and Vanersborg.

Max LOA 89m, beam 13.2m and draught 5.4m. Note: The aforementioned max dimension for transit through the Trollhatte Canal are only given through a special permit issued by the local administration. Request for special permit shall be sent by e-mail to: kctrollhattan@sjofartsverket.se. General max LOA 87m, beam 12.6m and draught 4.7m. Note: The aforementioned dimensions are the general max dimension for transit through the Trollhatte Canal. Max Barge and Towage: LOA 35m, beam 3m and draught 3m. (Total length from stern of towing vessel to end of towage: 60.0m). Max. airdraught (waterline to masthead height): 27.0m.

Approx. 3,500,000t of cargo and 1,000 vessels handled annually.

Swedish 1352 and 1353. Admiralty Pilot NP18, NP286(2).

The ordering of pilots and changes that may occur for the Pilot Stations in Trollhattan, and Vanern is carried out by VTS Trollhattan. Pilotage is compulsory for all category 1, 2 and 3 vessels and over LOA 60m, beam 9.0m, draught 4.0m, and vessels carrying more than 5t of explosives. Call Trollhatten Pilots or Vanern Pilots. A preliminary Pilot request must be made a least 24hrs in advance and a definitive pilot request made at least 5hrs in advance. Dangerous/noxious cargoes: A checklist, in accordance with regulations published by the Swedish Maritime Administration regarding special safety inspection of vessels operating on Trollhatte Canal and Lake Vanern, this must be filled out for all vessels requiring a pilot and which are carrying dangerous or noxious goods. The checklist must be completed within 24 hours upon arrival and before arrival at the pilot boarding area. The checklist should be handed over at the lock in Lilla Edet or Brinkebergskulle. Vessels from Lake Vanern to the canal at call point Galle Udde (58є28.34'N 12є28.18'E) must notify at Dalbo bridge and announce their vessel name and call point. During the winter months and in order to optimise wait times vessels to report to the canal centre in Trollhatten. Registrations must be made before departing Gothenburg, passage Dalbobron N and S bound and upon arrival to, and before departure at Vanerhamn.Pilot boards as follows: ..... 1. Vessels Northbound 57° 41.190'N 11° 52.220'E. 2. Vessels Southbound board the pilot N of the Dalbobron in Vanersborg. 3. Pilots are changed at the locks in Lilla Edet.

The flow of water through the canal is affected by the load on certain power plants, which may reach a maximum of about 2.5kts.

Except for the part covered by VTS-Gothenburg there is no VTS area within the Vanern Pilot Area. No vessel traffic service is provided and there is no formal maritime reporting system. Reporting shall be done to nearest bridge and lock according to Swedish Maritime Administration regulation. All bridges across the canal are remotely operated from the canal control centre in Trollhatten. See more at: http://www.sjofartsverket.se Procedure: During transit, all vessels shall maintain a continuous listening watch on VHF Ch 09 and VHF Ch 16. Instructions will be given to vessels at bridges, locks and on occasion from the Canal Office for completion of the canal transit. (On Lake Vanern, vessels should also maintain a continuous listening watch on VHF Ch 14). All vessels shall report before departure from any location stating departure time and destination. A request should be made on the current traffic situation. Vessels en route from Vanern to the canal should call Dalbobron 1 hours before arrival or at the latest on passage of Galleudde Light stating vessel's name, draught and ETA at Dalbobron. Vessels carrying cargo defined in SJOFS 1985: 19 (Water Pollutant decree) or carrying explosives over 5,000 kilos, shall notify the Canal Office 12 hours before arrival. Vessels should make contact on VHF on arrival to bridge, lock or regulated canal area. Vessels should notify the nearest lock or bridge of intention of anchoring. Further necessary information concerning traffic regulations when transiting the canal can be found in The Administration Decree (SJOFS 1993:28). Reporting: All vessels northbound and southbound should make a general call on VHF 09 when passing Lodose (58°02'N 012°09'E) stating vessel's name and heading. Bridges and Locks calling procedure: ..... Jordallsbron 1. Northbound vessels: at Slakhuset and dolphin 608 2. Southbound vessels: at Dosebacka (dolphin 536) and St Viken (dolphin 548) Stroms Sluss 1. Northbound vessels: at Pappersbruk (dolphin 412) and Lodose Varv (dolphin 455A) 2. Southbound vessels: at Esperod (dolphin 376) and Lodose Varv (dolphin 455A) Trollhattans Sluss 1. Northbound vessels: at lock Trollhattans Sluss on VHF at Dalen (dolphin 337) and Intagan (dolphin 313A) Jarnvagsbron 1. Northbound vessels: at Klaffbron 2. Southbound vessels: at Maloga (dolphin 225) Brinkebergskulle Slussen 1. Northbound vessels: at Onsjo (dolphin 212) and dolphins 143/146 2. Southbound vessels: at Vassbotten (dolphin 113) It is worth noting that merchant vessel have priority for passage throughout the canal including manoeuvring through locks and bridge openings. Whereas pleasure craft are only able to manoeuvre the bridges and locks between Lilla Edet and the bridge Gropbron in Vanersborg during 0900-1900hrs. As merchant vessels have priority, it may lead to pleasure crafts having to wait and queue. Locking times are shown on digital information signs located close to the locks

The canal normally freezes during the winter. In mild winters it freezes for fewer than 50 days (in a period between Dec-Mar) but in severe winters, it can freeze up for up to 100 days including the presence of close pack ice. Ice conditions in the Gota Alv are somewhat less severe. The canal is kept open for traffic throughout the year, with certain limitations on tonnage during the ice period. An ice breaker may be contacted at the canal centre in Trollhattan.
