Marine Structures’ Post

A Platform for Progress at Narrow Water Bridge Piling works have commenced at our Narrow Water Bridge site with help from a recently arrived marine piling platform. The project is a transformative link that will connect the Cooley Peninsula in Co. Louth and the Kingdom of Mourne in Co. Down and the northern and southern shores of Carlingford Lough for the first time. When completed, the bridge will: ✅ Provide access to the stunning natural beauty of Carlingford Lough ✅ Boost the region’s tourism and leisure potential ✅ Promote sustainable travel with pedestrian and cyclist-friendly infrastructure Over the next 8 weeks, 41 steel piles will be installed, a combination of permanent and temporary piles, with the temporary piles removed after the bridge is erected.

SF Marina is playing an important role in the Femern Link tunnel development by supplying floating concrete dock pontoons for the project’s tugboat pier. The 215m pier is comprised of ten 20m x 10m SF1850 floating concrete pontoons and one 15m-long centre section with a 28° end. This allows the array to gently angle away from the stone breakwater for double-sided docking. Heavy-duty SF1850 series pontoons are designed to handle the rigors of commercial use. Virtually unsinkable, they offer approximately 970kg/m2 of buoyancy yet are extremely stable. Strong and buoyant SF Marina W400 Connectors deliver two 105 tonnes per joint of breaking strength. Internal corner pile guides allow the pier to maintain its 1m freeboard while 21 aluminum bull bollards provide ample tie up locations. Eight rescue ladders and three ring buoy/fire extinguisher pedestals help ensure worker safety. The concrete pontoons were made at SF Marina’s Wallhamn, Sweden facility and transported to the site by truck. The company has six precast manufacturing locations across the globe and a robust delivery network to keep construction schedules on time and logistics expenses low. Strengthening links between Scandinavia and Central Europe, the Femern Link tunnel is Denmark’s largest infrastructure project. It’s part of a growing green traffic corridor throughout Europe. The 11-mile tunnel will connect the Danish island of Lolland with the German island of Fehmarn, reducing travel time from 45 minutes by ferry to a mere ten minutes and seven by electric rail. Back in April, a fatal accident at the Fehmarnbelt Tunnel site cast a shadow over the project. But the project is on track. Recently, His Majesty King Frederik X of Denmark officially inaugurated the first tunnel element. Keep up to date with the latest industry news on Maritime Journal; https://lnkd.in/edQ2kNkV

Beach renourishment-related operations have begun, both on land and in the water. This project will see 1.5 million cubic yards of beach-grade sand dredged from the shoreline of the Cape Canaveral Space Force Station (CCSFS) just north of Port Canaveral’s harbor entrance and moved southward onto the City’s beach. To help do this, engineers have installed what is called a booster station about 1,500 feet offshore the northern end of the City. This booster station (called Reggie (yes, that is its actual name)) will help “boost” (i.e., pump) dredged sand southward down the shoreline via a metal pipe and onto the beach to be spread out by work crews. Boaters, please be cautious of offshore construction activities. This booster station will remain in place throughout the duration of the project. A second booster station named Jack will be arriving later this month and will be placed south of the City offshore of Cocoa Beach to help push sand to the project’s “Segment 2” area between N. 2nd Street and Tables Beach.

🌉 The Dutch John Cut Bridge will take high-speed trains over the Dutch John Cut waterway that connects to the Kings River in Fresno County. When complete, the 6-span structure will span 669 feet in length and 43 feet in width. 🏗 The CIDH (Cast-in-Drilled-Hole) piles, which are essential for the bridge's foundation are on average 240 feet in depth and 11 feet in diameter, which makes them one of the largest uncased CIDH piles ever built in America and within the California High-Speed Rail Authority project. Watch the video below of Dragados Flatiron Joint Venture’s Segment 2A Manager, Jose Romero, and witness this massive undertaking. #EngineeringMarvel #Infrastructure #BridgeConstruction #CIDH KELLER

📣 New Case Study 📣 In June 2024, Irish Rail used a Geosynthetic Cementitious Composite Mat (GCCM) to line a 100m drainage channel along the Dublin-Belfast railway in Grangebellew, Co. Louth. Carra Plant Hire Ltd won the contract, with works starting in May 2024. 🔗 https://ow.ly/SqXN50UqsEL #ConcreteCanvas #ChannelLining

𝐕𝐚𝐧 𝐎𝐨𝐫𝐝 𝐚𝐧𝐝 𝐁𝐨𝐬𝐤𝐚𝐥𝐢𝐬 𝐜𝐨𝐦𝐩𝐥𝐞𝐭𝐞 𝐭𝐫𝐞𝐧𝐜𝐡 𝐟𝐨𝐫 𝐰𝐨𝐫𝐥𝐝’𝐬 𝐥𝐚𝐫𝐠𝐞𝐬𝐭 𝐢𝐦𝐦𝐞𝐫𝐬𝐞𝐝 𝐭𝐮𝐧𝐧𝐞𝐥 👷♂️🚧 Fehmarn Belt Contractors (FBC), a joint venture between Van Oord and Boskalis, has completed the dredging work for the tunnel trench of the Fehmarnbelt Tunnel between Denmark and Germany. Van Oord’s trailing suction hopper dredger Vox Amalia together with Boskalis’ trailing suction hopper dredgers Crestway and Shoalway recently dredged the last cubic meters from the 18-kilometer-long trench in the seabed after almost three years of dredging to create the trench. With this FBC is signing off on the dredging work for the tunnel trench. FBC’s dredging work is not quite finished, as the final part of this project, the embankments around the tunnel entrances on both the German and Danish sides will be removed, including dredging the underlying connection of the trench. Once this done in the next months, the installation of the tunnel elements in the trench by another contractor will start to form the longest immersed tunnel in the world. It consists of a direct road and rail connection between Germany and Denmark, thus becoming the fastest route between Scandinavia and Central Europe for both passenger and freight transport. 🚇 #VanOord #Marineingenuity #Dredging #MarineInfrastucture #WeSucceed

Cougar Infrastructure Project Update! 🚧 Exciting progress is being made on the Cougar Infrastructure Project.

𝗡𝗢𝗧𝗜𝗖𝗘 𝗢𝗙 𝗖𝗟𝗢𝗦𝗘𝗗 𝗪𝗔𝗧𝗘𝗥𝗦 | 𝗗𝗔𝗥𝗪𝗜𝗡 𝗦𝗛𝗜𝗣 𝗟𝗜𝗙𝗧 𝗣𝗥𝗢𝗝𝗘𝗖𝗧 Pursuant to subsection 50(1) of the 𝘗𝘰𝘳𝘵𝘴 𝘔𝘢𝘯𝘢𝘨𝘦𝘮𝘦𝘯𝘵 𝘈𝘤𝘵 2015 (NT), the waters surrounding the Darwin Ship Lift Infrastructure Development Project will be closed for backhoe dredging and barging operations from 0000 hours on 10 January 2025 to 0000 hours on 30 September 2025. The boundary of the closed area will be delineated by four yellow marker buoys placed in the following positions and depicted on the map: •       12° 29.5008 S. 130° 53.7493 E •       12° 29.6701 S. 130° 53.8045 E •       12° 29.6705 S. 130° 54.1471 E •       12° 29.4171 S. 130° 54.1440E Access to the shipping channels in pilotage zones C (East Arm Wharf), F (Hudson Creek, Bladin Channel and Elizabeth River) and G (Darwin Marine Supply Base) will not be impeded. All persons and vessels not directly involved in the project are required to keep clear of the closed waters for safety reasons.

Dumping the base layer materials with loaders and stabilizing the slope with excavators is the method of constructing the ground for the breakwaters. This is the method of marine construction, but it depends on the conditions of the project and the facilities. 👌 Jarjoub Sea Port Breakwater

Brief Thoughts on Drones and Civil Construction The article below is one of what is becoming a flow of affirmative and positive disclosure that drone technology is increasingly used to observe as well as monitor civil construction in progress. Kudos to Stevens Cresto Engineers for their collaboration with Chad Bunn and CMB Services, utilizing the CMB drone technology to record the progress of this important project. I have been curious, impressed, somewhat excited, as well as intrigued by the potential of drone-applied technologies. In the civil construction industry sector drones are useful for video and still photography, as well as photogrammetry and now LIDAR data collection. Integrated with data processing technology from companies like Propeller, used by CMB Services, and Trace Air, used by a growing number of companies, the daily, weekly and monthly accrual of information, held in an electronic format for ongoing access is almost staggering. I have personally utilized the technology record to go “back in time” to see the captured images of work in progress. It literally changes the conversation when the record shows the “when and where” of a question. I’m of the opinion that drone technology in civil engineering and construction should be embraced. It changes the appeal of our industry. Will we continue to work hard at our industry? Well, yes. Civil construction is inherently labor intensive and thus, somewhat unattractive from that perspective. But the reward of hard work is the culmination of a project that serves our community. Drones can capture that process and that historic narrative enhances the “cool” factor. Chad Bunn Stevens Cresto Engineers
