The article supplies unusually strong cavern geometry: three unlined oil-storage chambers, each 16 m wide, 25 m high and 255 m long. Their clear internal volume is 102,000 m³ each and 306,000 m³ total, while their chamber-floor footprint is 12,240 m² / 131,750 ft². It also identifies four-metre-thick locks, two levels of end connection tunnels, groundwater-pressure sealing, automatic water pumping, and product heating to 55 °C. It provides no historic construction cost or storage/process capacity in tonnes.

Reviewed 15 August 2026 · geometry completeness 86/100 · Medium for civil geometry; low for total replacement cost
The model correctly multiplies the three chamber dimensions to 306,000 m³, but incorrectly states that chamber height is unpublished and then creates a 17,000 m² / 182,986 ft² floor-area proxy. The published footprint is 12,240 m² / 131,750 ft². More importantly, 306,000 m³ is clear internal volume, not necessarily solid design excavation; crown, overbreak, access and support need uplift. The SEK 4.076bn base lacks an explicit current oil-heating/transfer/fire/containment process package and scales protection by area, so it is not a complete functional replacement.
published: three chambers; 16 m width; 25 m height; 255 m length; 306,000 m³ total clear chamber volume; 12,240 m² / 131,750 ft² chamber-floor footprint; two-level end connections; one protected access behind four-metre locks | not_published: crown shape and overbreak; connection-tunnel lengths/sections; portal topology beyond the described access; excavated solid-rock volume; pump galleries and plant-room dimensions
water-bed/unlined groundwater containment; automatically regulated groundwater pumps; 55 °C product heating; upper and lower connection tunnels; oil transfer/pump system implied
large clear cavern volume plus overbreak/access; support and hydrogeology; continuous groundwater control; oil heating and transfer plant; fire/explosion safety and containment; heavy locks and connections
One active Karlshamnsverket storage complex of three chambers.
Correct the factual error and use 12,240 m² / 131,750 ft² published footprint; treat 306,000 m³ as clear-volume lower bound and add crown/overbreak/access scenarios; calibrate large repetitive cavern rates separately from small bunkers; add hydrogeology, pumping, monitoring and water management as their own line; add oil heating, transfer, fire/explosion and containment process modules; supplier-budget the four-metre locks
survey sections/crown geometry; access/connection tunnel quantities; rock/support class; groundwater inflow and pumping duty; storage tonnes and oil specification; heating/transfer/fire systems schedule; modern environmental and safety brief
published 25 m height is incorrectly labelled missing; published 12,240 m² / 131,750 ft² footprint is replaced by an unnecessary proxy; clear volume is mislabeled as solid design excavation; process plant is under-specified; active-site publication sensitivity
