Terramare handed the new S1 pier to Port of Turku in June 2026, completing the first construction contract in the Ferry Terminal Turku programme. The berth remains outside passenger service until March 2027 because the terminal, passenger gangway, three boarding bridges, traffic systems, field circulation and operating interfaces must still converge. The nine-month interval separates marine-civil handover, system commissioning and first service.

The evidence moved from construction to interface readiness

Port of Turku is the primary source for physical progress, contractor roles and operating dates. TED award records control the two disclosed values. The owner's current pages describe S1 with different length and pile metrics; the brief preserves the discrepancy rather than manufacturing a single as-built number.

A complete pier is still one component

The S1 structure is substantial: long steel piles through clay, about 12,000 m3 of concrete, a hydraulic vehicle ramp, underwater erosion protection and extensive diving. Yet the first scheduled vessel call sits nine months after handover. That gap is not idle time by definition; it is where access bridges, passenger processing, terminal systems, traffic control, ship clearances, emergency procedures and operator readiness become one usable berth.

Evidence conclusion

System commissioning gates remain open

S1's June 2026 owner handover is a confirmed marine-civil milestone. It does not close the wider project or establish an operating berth. Remaining milestones are Skanska's gangway and bridge installation, terminal completion, Weasel Software's traffic system, field access and drainage acceptance, integrated operational tests, the March 2027 first Tallink Silja call and defects follow-up. Quay S2 remains a separate 2028 package. The EUR 20.55 million S1 and EUR 14 million field awards produce a EUR 34.55 million disclosed subtotal, not a whole-programme budget or final account.

Outstanding evidence

  • S1 gangway and three boarding-bridge installation and testing
  • Terminal occupancy approval and passenger-flow readiness
  • Hydraulic ramp, fender, mooring and ship-clearance acceptance
  • Passenger and traffic-management system commissioning
  • Field drainage, utility, lighting, security and traffic acceptance
  • First Tallink Silja call in March 2027
  • Reconciliation of conflicting owner-published pier length and pile metrics
  • S2 award, automooring transfer and 2028 operating gate
