Owner reports offshore construction progress and expects bulk-import operation in Q2 2027

Project sources

Sizewell C is constructing a temporary bulk-import jetty and conveyor connection to its main site. The owner forecasts Q2 2027 operation; the marine licence defines the berthing structures and separate capital and monthly maintenance-dredging ceilings.

Project anatomy

Contract scope and delivery roles

Client / authority
Sizewell C Limited
Delivery parties
Notice 29 assigns the planned jetty-head work to the jack-up vessel Wind; the reviewed records leave the package's commercial contractor unspecified.
Contract route
Owner and harbour records describe construction and the marine delivery plan. The amended deemed marine licence authorises Work 1A(aa); commercial award, payment and cargo-handling agreements require their own contract records.
Execution window
The 15 April 2026 forum recorded Canti-travel piling in progress. Notice 29 planned phase two from around 2 July for approximately four months. The live owner tracker reports works through the end of 2026 and forecasts operation in Q2 2027.
Works package
Temporary bulk-import pier carrying a covered conveyor and access road up to 468 m long and 12 m wide; a head approximately 50 m by 50 m, excluding Canti-travel access spurs; three berthing dolphins and two mooring dolphins; navigational lighting; a dredged berthing pocket and subsequent removal before power-station operation.
Marine interfaces
The phase-two plan joins offshore head construction from Wind to the approach trestle advancing seaward by Canti-travel. Cargo reception depends on the berth, berthing structures, conveyor connection and the main site's receiving route becoming available together.
Commercial evidence boundary
The marine licence caps capital dredging at 11,675 m3 and maintenance at 1,170 m3 per month within the berthing pocket. Condition 32 ties each dredging phase to an approved method, dates, volume, depth and vessel set. Dredging recovery, structural handover and mechanical commissioning can each affect the first cargo's usable arrival slot.

Evidence gap

What remains unverified

Outstanding evidence

  • Current head, trestle and conveyor progress and commissioning dates
  • Approved dredging phase, dated survey, pocket depth and vessel operating draught
  • Berthing-system handover and main-site aggregate receiving capacity
