Cylindrical offshore mooring foam #buoys are buoyancy devices used for mooring and stabilization purposes in offshore applications. 

Recent trends in North Sea bed testing highlight advancements in equipment and methodologies to enhance geotechnical investigations, particularly for offshore wind farm development. 1. Advanced Cone Penetration Testing (CPT) Systems: One of the significant trends is the use of advanced CPT systems like Geoquip Marine's GMC200. This system provides detailed profiles of tip resistance, sleeve friction, and pore water pressure. It is designed for rapid deployment and operation in both shallow and deep waters, capable of seabed penetration up to 40 meters and functioning at water depths of up to 2000 meters [[❞]](https://lnkd.in/daAPUiU3). 2. Free-Fall Cone Penetrometers (FFCPT): These are increasingly utilized for deep-water geotechnical investigations. The new 4000-meter cone penetrometer, as tested off Crete, Greece, exemplifies this trend. FFCPTs allow for rapid assessment of seabed characteristics, which is crucial for understanding sediment behavior and stability, particularly in landslide-prone areas [[❞]](https://lnkd.in/dddNJwys). 3. Integration with Offshore Wind Development: Companies like Fugro are converting platform supply vessels (PSVs) into specialized geotechnical vessels to meet the growing demand for offshore wind farm site investigations. This includes deploying advanced geotechnical testing labs and equipment onboard to ensure precise and comprehensive data collection [[❞]](https://lnkd.in/dvC8zvdv). 4. Correlation and Calibration Improvements: A critical area of research is improving the correlations between CPT data and soil properties like small-strain shear modulus. Studies highlight the need for location-specific calibration, considering the unique geological conditions of the North Sea, to enhance the accuracy of foundation designs for offshore wind turbines [[❞]](https://lnkd.in/d3hdAadq). These advancements are driven by the increasing complexity of offshore projects and the need for more reliable data to support the design and construction of robust marine structures.

A chain is only as strong as its weakest link. Several type of offshore structures such as FSO/FPSO and SBM/CALM buoys utilize anchor chains to hold in position. It is common to see multiple anchor chains for each structures. Not small chain like bicycle chain. A single link chain for these structures can be almost 1m long and weight at few hundreds kilogram. A broken anchor chain is no good. It doesn't serve its purpose. Later the FSO or SBM buoy would float away if all anchor chains fails. Hence it is important to check the condition of the chain links at the high stress area & corrosion is mostly expected. The subsea inspection performed on the anchor chain are: ⚠ Visual Inspection ⚠ Marine Growth cleaning of chain links at selected location ⚠ Selected Chain Links Wear measurement to record its current dimension to compare with as-built data ⚠ Measurement of corrosion pitting if observed ⚠ CP measurement ⚠ Chain angle measurement These data would be utilize for analysis and understand where is the weakest link, so the necessary remediation work can be performed if necessary. As the weakest link would be the anchor chain's Achilles heel. #worklife #pakciksubsea #offshore #oilandgas #oilandgasindustry #subseainspection #subseairm

Zinc anodes are a crucial component of cathodic protection solutions, especially in environments where metal structures are exposed to seawater or other corrosive conditions. Zinc anodes protect a variety of submerged metal structures such as pipelines, marine vessels and offshore structures by sacrificing themselves to protect the important infrastructure asset. The benefits of using zinc anodes include their reliability in saline environments, cost-effectiveness and ease of installation and maintenance. If you have an underwater environment or infrastructure that needs to be protected from corrosion, contact a Farwest Representative today. #CathodicProtection #CorrosionControl #CorrosiveConditions

Unsurprisingly, there are many factors to consider when investing significant time and money into building an offshore wind farm. One factor that may not be top of mind for most people is the detection of potential unexploded ordnance: bombs or other explosives underwater that have not detonated as intended. This material poses a significant hazard and must be identified and removed quickly and safely during the building process. See how Nortek's VM Operations system played a part when performing this type of challenging survey: https://bit.ly/48AXbfP
