Fehmarnbelt: IVY's 1,600-Tonne Load Test

Fehmarnbelt's September load test addressed a change in transport geometry. The first special tunnel element has a basement and must travel higher in the water than a standard element. Raising it reduces buoyancy and transfers more load to the immersion vessel IVY. Sund & Bælt reported on 11 September 2026 that the fourth standard element had been loaded with an additional 1,600 tonnes, distributed between water bags on its roof and tanks inside it, and lifted to the height required for transporting the special element.

Davis prepares water-plant modules for an over-ice resupply

Australia's Antarctic programme is sending a containerised pump house, a reverse-osmosis plant and earthmoving equipment to Davis for the 2026-27 construction season. Its 20 October departure account puts RSV Nuyina's planned resupply position about one kilometre from station buildings. More than half of the voyage's cargo of over 950 tonnes is assigned to infrastructure renewal. AAD's V1 schedule lists an over-ice resupply at Davis from 4 to 13 November. [1][3]

Melaka sets a buoyed work area for power-plant mud removal

Malaysia's Marine Department has published a mud-removal work area for the Melaka 2,242 MW combined-cycle power plant, with a stated period from 7 October 2026 to 15 June 2027. Port Circular 52/2026, dated 12 October, identifies four boundary points and names anchor-handling tugs JETTA 35 and JETTA 37 and barges JETTA 39 and LIGHT SABER. It advises other vessels to keep clear of the work area and navigate cautiously nearby. [1]

Sizewell targets Q2 2027 bulk imports as jetty works advance offshore

Sizewell C expects its Marine Bulk Import Facility to become operational in the second quarter of 2027. The owner's works tracker reports that construction has advanced from the beach into the sea, with platform works continuing through the end of 2026. The facility will transfer bulk materials from vessels to the main construction site. April's site forum recorded Canti-travel piling in progress; the harbour's subsequent phase-two plan paired offshore jetty-head construction with an approach trestle advancing seaward from the mainland.

Gulfport's deepening plan includes a later sponsor payment

Gulfport's recommended navigation improvements carry two different sponsor payments. The signed 23 June 2026 Chief's Report assigns $137.102 million of the $548.216 million initial project cost to the Mississippi State Port Authority. It also estimates an additional General Navigation Features payment at $50.8 million, before eligible credits. Paragraph 9(d) places that additional payment after construction, with interest, over a period of up to 30 years. A sponsor's funding forecast therefore needs a construction contribution and a separate post-completion repayment schedule. Annual federal operation, maintenance, repair, replacement and rehabilitation (OMRR&R) is estimated at $17 million, including anticipated maintenance dredging. [1]
