Skandia Gateway in Gothenburg

The Port of Gothenburg is the only port in Sweden used by the world’s largest container vessels and provides direct routes between Sweden and the Far East. However, the depth of the fairway and turning area must be increased in order to maintain the port’s strategic importance.

Name of project: The Skandia Gateway – Deeper fairway in the Port of Gothenburg.

Where: Gothenburg. Widening and deepening of the northern fairway to the Skandia Harbour and the turning area.

Planned implementation period:  August 2025 to May 2027; if possible, the start of construction can be brought forward one year. A decision about the implementation period will be made before summer 2022.

State of maturity: Main hearing in the Land and Environment Court ends on April 1st 2022, with an environmental permit expected in May 2022. In case of an appeal, permit may be delayed about 12 months.  

The financing of the project is secured.

Planned depth: Maximum depth for dredging is 20.5 m in the outer part of the fairway. In the inner part the maximum depths are 19.4 and 19.25 m.

Preliminary dredging volume: Approximately 13.5 million m3 in situ.

Approximate distribution of rock/dredgable material: Approximately 13 million m3 of clay and about 340,000 m3 of rock in situ.

Known contaminated material?/Management of contaminated material?: Approximately 285,000 m3 of clay in situ is classified as contaminated material. The project is applying for an environmental permit for dumping contaminated spoil at sea and cover these with around 10 m of clean dredged clay.

Potential distance to disposal site or landfill site: The project is applying for an environmental permit to dispose all spoil at sea. The intended disposal site is located around 8–10 nautical miles from the dredging area.

Potential difficult traffic situation: As the work area is located in and around the existing fairway, there is a lot of traffic and stringent demands for coordination with the Swedish Maritime Administration’s Vessel Traffic Service (VTS) and the Port of Gothenburg, among others. There is also a southern fairway to Gothenburg that can be used to reduce traffic in the northern fairway.

Special conditions: The project is being implemented in partnership with Port of Gothenburg. The Swedish Maritime Administration is responsible for dredging the fairway and adjusting the fairway markings. The Port of Gothenburg is responsible for dock measures, including the dredging 50 m from docks.

It shall be noted that a similar dredging project was conducted in Gothenburg over the years 2002–2004. Therefore, the area and the risks are well known.

Estimated production time: Approximately two seasons, with a break in disruptive works between the middle of May and the middle of August.

Type of contract: Not decided.

Procurement process, tender period, pre-qualification: A formal decision regarding the procurement process is being made before summer 2022. If production is to start in August 2025, the procurement will be advertised around the turn of the year 2023/2024, with the contract being signed before the end of 2024. If production is to start in August 2024, the project expects procurement to be advertised in early spring 2023.
