Project record
Oslo Kneppeskjaer East quay replacement and expansion
Oslo Havn; exact Kneppeskjaer East foundation-work update published in February 2026
Port of Oslo awarded Repstad Anlegg an approximately NOK 250 million design-build contract to replace and extend Kneppeskjaer East. The owner describes a continuous 284-metre quay front, two ship ramps and at least 12.5 metres of depth, while the contractor uses a rounded 300-metre description. Demolition, dredging and subsea blasting moved into a 99-steel-pile foundation stage in 2026. Multiconsult and Norconsult hold distinct environmental-control roles.
Segment
Multipurpose quays, dredging and carbon-logistics infrastructure
Status
Repstad Anlegg began works in August 2025; demolition, dredging and subsea blasting preceded a 99-pile quay-foundation programme scheduled from March to July 2026 / Confirmed

Project anatomy
Contract scope and delivery roles
- Client / authority
- Oslo Havn KF, the Port of Oslo municipal port authority
- Delivery parties
- Repstad Anlegg AS - design-build main contractor for demolition, subsea blasting, dredging, concrete works and quay construction, Multiconsult - independent ecological and chemical monitoring and control before, during and after the works for the port authority, Norconsult - environmental adviser to Repstad for turbidity, noise, pollution and biodiversity planning and control, No reviewed primary source names downstream piling, dredging, blasting, concrete or marine-plant subcontractors
- Contract route
- Oslo Port awarded a design-build contract to Repstad Anlegg, an Endur subsidiary, in June 2025 for approximately NOK 250 million. The main contractor integrates demolition, seabed work, structures and quay delivery while environmental control is split between the owner's independent adviser and the contractor's adviser.
- Execution window
- Repstad mobilised in late July and early August 2025 for an approximately 20-month programme. Oslo Port reported foundation work beginning in March 2026 after demolition, dredging and subsea blasting, with the 99-pile driving programme targeted for completion in week 29 of 2026.
- Works package
- Demolish and replace the northern quay, extend the southern quay, create a continuous quay front stated as 284 metres by the owner and 300 metres by the contractor, install two ship ramps, deepen the basin to at least 12.5 metres and complete associated concrete and marine works. The quay is intended to support general cargo and future liquid-CO2 logistics.
- Marine interfaces
- Dredging and underwater blasting establish the basin and foundation workfront before 99 steel tubular piles, concrete deck works and ship ramps can be completed. Turbidity, underwater noise, contaminated sediment and biodiversity controls form explicit release conditions throughout the sequence.
- Commercial evidence boundary
- The top-tier contract, value and environmental roles are unusually clear. The downstream plant and subcontract chain is not public. The owner has published a construction-stage transition into piling but no as-built depths, accepted dredging quantities, final pile completion or quay handover.

Dated events that changed scope, counterparties, delivery, commissioning or operating status.
Open this project in the Change LogThe quay moved into its 99-pile foundation stage
Oslo Port placed the project after demolition, dredging and underwater blasting but before concrete quay completion and handover.
SourceRepstad mobilised under active environmental controls
Oslo Port identified both environmental advisers and the monitoring measures governing demolition, dredging, noise, turbidity and contaminated sediment.
SourceRepstad received the design-build contract
The approximately NOK 250 million award placed demolition, dredging, blasting, concrete and quay works under one main contractor.

What remains unverified
Outstanding evidence
- Completion of 99 steel tubular piles
- Owner 284-metre versus contractor 300-metre geometry
- Post-dredge bathymetry and minimum 12.5-metre depth
- Concrete deck and two ship-ramp completion
- Turbidity, noise and contaminated-sediment compliance
- Downstream marine-plant and subcontract allocation
- Quay handover and liquid-CO2 logistics readiness
