🌍✈️ Gavin Donnelly and David Hand Boyd from our Rockbags team are on the move again this week; they are attending WindEurope in Copenhagen. They're catching up with clients and connecting with some of the leading figures in global Wind Energy. We’re currently involved in a range of exciting projects and challenges around scour and cable protection—areas where our patented Japanese Filter Unit® Rockbags have been making a real difference. For over 15 years, they’ve played a key role across Europe, Asia, and the UK, delivering cost-effective, sustainable solutions to protect our clients’ critical subsea assets. 🌊🔧 www.rockbags.com #WindEurope2025 #Rockbags #SubseaSolutions #CableProtection #SustainableEngineering #OffshoreWind #EngineeringExcellence #SubseaProtection Northern Ireland Maritime & Offshore

A new method for scour monitoring based on distributed fiber optic vibration sensing Yinghao Lin, Dongjian Zheng , Cheng Ran Riverbed scouring caused by water flow is a major factor in dike damage, and traditional optical fiber technologies for monitoring scour are limited due to cost and durability concerns. This study presents an advanced solution: a riverbed scouring sensing rod using distributed optical fiber vibration sensing technology based on Adaptive Threshold Brillouin Optical Time Domain Analysis (AT-BOTDA). The new method leverages dynamic strain transmissibility and its gradient to estimate scour depth more efficiently. Unlike traditional point-type methods, AT-BOTDA allows high-speed, distributed strain measurement, enhancing monitoring accuracy without the need for full-spectrum scanning. Model experiments validated the method under both dry and dynamic water conditions. The results show that dynamic strain transmissibility and its gradient provide reliable scour depth monitoring, even accounting for changes in water level. The gradient-based method proves superior, with a relative error of less than 6% in scour depth estimation. This cost-effective and adaptable approach promises more effective scour monitoring, ensuring the safe operation of dikes and improving environmental resilience.

Filter Unit® Scour Protection Physical Model Tests.(Test2) Kyowa commissioned the National Renewable Energy Centre (NaREC) to procure and supervise a set of hydraulic physical model tests at HR Wallingford to demonstrate the effectiveness of Filter Unit® as scour protection around monopile foundations in typical North Sea conditions. The key objective of the physical model tests on the Filter Unit® scour protection system is to allow its performance to be independently tested to inform Kyowa’s purpose of effectively marketing and ultimately selling the product, in the first instance to developers of round 3 offshore wind farms, where monopile diameters of over 6.0 m are likely to be used. The testing should simulate the representative combined wave and current conditions. The project allowed for 20 tests to be undertaken, with two monopiles in each test. The twenty tests were split into seven test series. Each of the initial test series consisted of a number of tests, building up to a test that was expected to induce some movement of armour or failure of the scour protection system. TEST 2: A third layer of filter units was added to the first ring (against the monopile) before Test 2 was conducted, in order to reduce the loss of sediment observed during Test 1. There was no displacement of the filter units around the edge of the model with no additional settlement of the filter units visible, close to the monopile. The riprap scour protection system has started to lose a small amount of material around the sides and at its downstream edge. The top surface is less even than it was, with some lowering of the top surface close to the monopile. Some sand has settled on top of the scour protection system near the upstream edge. Erosion also occurred at the front of the sand bed. This was due to turbulence caused as the current flow passed the transition from a solid concrete bathymetry to the sand bed. Moreover, there was no feed of sand from upstream to compensate for these losses. #Ridgeway #GlobalOffshore #SubseaEngineering #CableStabilisation #OrkneyIslands #OffshoreProjects #MarineInfrastructure #SubseaTechnology #Rockbags #FilterUnits #OffshoreEnergy #RenewableEnergy #UnderwaterConstruction #OffshoreSupport #MarineSolutions #SeabedStabilisation #KirkwallPort #EngineeringExcellence #CoastalProtection #SustainableInfrastructure #OffshoreInnovationw

We are looking forward to seeing old and new friends in Copenhagen this week.

TEST 1: Test 1 was completed using only currents. The current only condition caused low levels of scour around both models leaving typical bed ripple patterns across the model.   completion of the test, to show how uniform the response of the sand bed was to the currents, across the entire sand bed. The bed elevation plots for before and after the tests are shown side by side. The use of the commercial laser scanner allowed the entire sand bed and both scour protection systems to be accurately surveyed. The system is accurate enough to pick out individual filter units, based on the small variations in their surface elevation. #Ridgeway #GlobalOffshore #SubseaEngineering #CableStabilisation #OrkneyIslands #OffshoreProjects #MarineInfrastructure #SubseaTechnology #Rockbags #FilterUnits #OffshoreEnergy #RenewableEnergy #UnderwaterConstruction #OffshoreSupport #MarineSolutions #SeabedStabilisation #KirkwallPort #EngineeringExcellence #CoastalProtection #SustainableInfrastructure #OffshoreInnovationw

Innovative Application of Filter Unit® Rockbags in Coastal Defense Project. Ridgeway Rockbags implemented an eco-friendly solution using 4T Eco-green Filter Unit® Rockbags to ensure uninterrupted water flow from multiple outfall pipes along the southern coast of England. The primary challenge was preventing sediment and debris buildup around the pipes, which could obstruct drainage and lead to flooding risks. Thanks to the permeable design of the Filter Unit® Rockbags, water passes through effortlessly while effectively filtering out blockages. This sustainable approach not only safeguards the coastal infrastructure but also supports environmental conservation by maintaining natural water circulation. Ridgeway Rockbags and Bluemont Pty Ltd deliver reliable, sustainable solutions for coastal erosion challenges by Kyowa Filter Unit® Rockbags. #Ridgeway #GlobalOffshore #SubseaEngineering #CableStabilisation #OrkneyIslands #OffshoreProjects #MarineInfrastructure #SubseaTechnology #Rockbags #FilterUnits #OffshoreEnergy #RenewableEnergy #UnderwaterConstruction #OffshoreSupport #MarineSolutions #SeabedStabilisation #KirkwallPort #EngineeringExcellence #CoastalProtection #SustainableInfrastructure #OffshoreInnovationw
