Port of Luleå Malmporten fairway and deepwater port works

Dredging vessel and support craft in a harbour approach, published by the Swedish Maritime Administration with its Malmporten contract update

Swedish Maritime Administration

Malmporten has moved through a completed 2024 preparatory dredging package, an over-budget main tender, a redesigned procurement and a signed SEK 5.7 billion Boskalis-Van Oord contract for roughly 14 million cubic metres of remaining fairway and harbour works.

Project anatomy

Contract scope and delivery roles

Client / authority
Swedish Maritime Administration and Port of Luleå
Delivery parties
Malmporten Dredging Contractors, Boskalis, Van Oord
Contract route
Joint public-authority capital works contract retendered after an over-budget procurement; approximately SEK 5.7 billion / EUR 500 million
Execution window
Execution from spring 2027 through the ice-free seasons, with completion required before mid-August 2030.
Works package
Remaining works to deepen approximately 40 km of fairway and the harbour basin, dredge about 14 million m³ of mixed sediment and fresh rock, and reuse suitable material for deepwater-port land reclamation, following a separately executed 2024 preparatory package.
Marine interfaces
Capital dredging, drill-and-blast, environmental controls, navigational-access improvement, land reclamation, and an ice-constrained execution calendar are combined in one major works package.
Commercial evidence boundary
The failed first main tender makes scope control and production credibility as important as headline fleet capacity. The signed package now concentrates mixed geology, drill-and-blast, seasonal productivity, turbidity control and reclamation interfaces into a 2027-2030 window, while the separately stopped quay procurement remains an external port-readiness dependency.

The remaining dredging contract was signed

The owners moved the main dredging package from conditional award to a signed approximately SEK 5.7 billion contract for about 40 kilometres of fairway, with execution from 2027 and completion by 15 August 2030. Signing does not prove fleet mobilisation, accepted depth, reclaimed land or deepwater-port readiness.

Malmporten Dredging Contractors received the main-works award

The owner announced a roughly 14-million-m³ optimized scope and planned contract signing after the review period. The record at that gate established an award decision; the signed contract followed on 2 July.

Source

The owners launched an optimized two-stage retender

A redesigned fairway scope returned to market through prequalification and invited bids. The later owner release describes the previous procurement as cancelled in September 2025, while the authority's detailed status record says the common tender had been stopped in February; The two descriptions remain separate rather than being collapsed into one event.

Source

The common dredging tender exceeded budget and was stopped

The Swedish Maritime Administration says the submitted bids exceeded budget and that the deepwater-quay procurement was also stopped. The subsequent design optimization was intended to reduce cost without changing capacity, safety or function.

Source

The preparatory dredging package finished on plan

The authority records completion of the 2024 preparatory works in October. That package was physical progress, but it did not complete the remaining fairway, harbour-basin, quay or deepwater-port works.

Source

Preparatory dredging entered field execution

Optimus and Kahamari 2 started in the harbour area, followed by Magnor in the Sandgrönn fairway and planned support from Simson. The fleet disclosure is evidence of active preparatory production, not completion of the later main contract.

Source

The first preparatory dredging contract was signed

The approximately SEK 655 million base package, with a further option, covered roughly 1.5 million m³ in the harbour and part of Sandgrönnleden before winter. Its quantity and value must remain separate from the later remaining-works contract.

Source

The market dialogue published the original whole-program baseline

The early owner brief described about 22 million m³, around 1 million m³ of rock, parallel port construction and normal operations, and an April 2024-December 2026 concept. These were procurement-planning assumptions and are not the current 14-million-m³ remaining-works contract.

What remains unverified

Outstanding evidence

  • Spring 2027 mobilization
  • Ice-free-season production plan
  • Rock excavation and drill-and-blast sequencing
  • Reclamation and deepwater-port interface dates
