A rock structure specifically designed to protect subsea power cables is essential for ensuring the safety of these vital assets against environmental hazards and human activities. Below are key components along with brief descriptions: Berm: The berm is a critical element in subsea cable protection strategies, providing a robust physical barrier that enhances the stability and longevity of underwater cables. Its design and implementation are key to ensuring the reliability of subsea infrastructure in challenging marine environments. Armour Layer: This outer layer of a rock berm offers essential protection for subsea cables against hydrodynamic loading from waves and currents. By utilizing larger, durable materials and employing careful construction techniques, the armour layer helps maintain the integrity and reliability of subsea cable infrastructure. Proper design and maintenance are crucial for sustaining its protective capabilities in demanding marine conditions. Filter Layer: The filter layer is a vital protective component for subsea cables, helping to control sedimentation and providing additional protection against environmental factors. By facilitating proper drainage and minimizing abrasion, the filter layer contributes to the overall longevity and reliability of subsea cable systems. Toe Area: The toe area refers to the bottom part of a protective structure, such as a rock berm or revetment. It plays a significant role in stabilizing and protecting the structure from erosion and external forces. Proper design and construction of the toe area are essential for ensuring the effectiveness of protective measures over time. Falling Apron: This engineering feature is crucial for coastal and underwater protection strategies. By dissipating wave energy and preventing erosion, the falling apron contributes to the stability and integrity of protective structures, ensuring the long-term reliability of subsea cables and coastal defenses. Effective design, material selection, and maintenance are essential for the falling apron’s success in various environments. These components work together to form a comprehensive protective system for subsea power cables, shielding them from environmental hazards, erosion, and human activities. Each element is vital for ensuring the longevity and reliability of subsea infrastructure, making effective design and implementation crucial for protecting these critical assets.

With the ceiling height being only 2.3 metres we deployed our low headroom windowless rig to a site in London. Being able to drill with ceiling height as low as 1.9 metres using 0.5 metre samplers and rods this rig is invaluable because it can get to a position where a standard windowless rig cannot drill. This rig can still undertake spt’s, dynamic probes and Install monitoring wells.

VESSEL REVIEW: Orange, Texas-based marine projects company Muddy Water Dredging recently took delivery of a new bespoke maintenance and navigation support dredger built by DSC Dredge of Reserve, Louisiana. Named 'Vaneta Marie', the dredger is what DSC Dredge claims as one of the largest cutter suction dredgers (CSDs) built in the United States with a length of 371 feet (113 metres). The vessel is capable of 24/7 operation and dredging a 400-foot (120-metre) wide cut with an 80-degree swing arc. The latter attribute is important as it allows the dredger to fulfil its original design brief, which called for a vessel that will easily clear the Calcasieu River in southwestern Louisiana in a single pass. This capability means that boat traffic can pass through the river without having to shut down operations just to move the dredger. Full article link in comments.

Attention #geotechnicalengineers, #bridgeengineers and #marineengineers: #Ship impacts can apply massive loads on #bridge piers. In this example, I took a typical 100k vessel impact load, applied 30 ft above the cap initially, and progressively increased the load to 20000 k, which is likely close but perhaps smaller than the load that the Francis Scott bridge experienced. This is an imaginary bridge pier with 12 - 90 inch diameter piles. At the 100k typical #ASCE7-22 impact load the pier displaces about 0.5 inches. At 20000k the displacements increase to 29 inches and the piles fail structurally. The analysis was performed with our #DeepFND #deepfoundation software and included water flow loads. This unfortunate event reminds us that the public should pay more attention to our #infrastructure before it collapses. Follow Deep Excavation LLC for more.

Part 2 🔷Did you knew that cone penetration test can be done underwater in the sea ? It’s use to determine the area that can care a load of permanent structure by using sensors that send back (friction) and soil (resistance) value in the machine . -with the help of this technology the imagineers can know how deep the ship piles must be driven. #civilengineering #geotechnicalengineering #construction #bridge #building #soil #soiltest #geotechnicaltest
