Tunnel Thrusters & DP Operations: Silent Control with propper Ducted Propellers. In offshore operations, precision is not optional — it’s the standard. Tunnel thrusters fitted with ducted (nozzle-type) Kaplan CPP provide high thrust at low speeds for responsive lateral movement, station-keeping accuracy, and tight maneuvering — even under adverse conditions. The nozzle improves bollard-pull efficiency, reduces tip-vortex losses, and stabilizes inflow close to the hull. Critical detail — blade-to-tunnel tip clearance. Efficiency and acoustic performance depend on keeping the gap between blade tip and tunnel exactly as specified by the OEM manual. Clearances set too small raise the risk of contact, vibration, and cavitation; too large and the jet weakens, recirculation increases, and bollard-pull drops. Maintain concentricity and alignment under load, account for coating thickness and deformation, and inspect regularly to preserve the design clearance. Design notes for DP excellence • Kaplan geometry with controllable pitch for fine thrust resolution at low speed • Entrance radius and exit flare of the tunnel to minimize losses • Variable-speed electric drives integrated with DP control laws to reduce acoustic footprint Because holding position isn’t about power — it’s about precision in motion. #TunnelThrusters #KaplanCPP #DynamicPositioning #DuctedPropeller #BollardPull #Hydrodynamics #NoiseControl #MarinePropulsion #OffshoreOperations #VesselPerformance #NavalArchitecture #SustainableShipping

A proportional valve is a hydraulic or pneumatic valve that precisely controls flow or pressure continuously, rather than simply opening or closing (as with a simple on-off valve). Spider cranes equipped with proportional valves ensure smooth boom movement (no sudden jerks when raising or lowering) and load positioning with millimeter-level accuracy. The operator's joystick or remote control sends a signal to these valves. How a proportional valve works: It receives an electrical signal (voltage or current), typically from a controller or remote control. The valve then adjusts its opening proportionally to this signal. This allows for very precise control of actuator speed, force, or position. Proportional valve configuration is crucial for spider cranes. #Proportionalvalve #spidercrane #minicrane #compactcrane #glassinstallation

Cutting steel pipes 100 meters below sea level? No problem—with hydraulics. One of the most extreme applications of hydraulic systems is a subsea diamond wire saw, designed to cut through pipes, beams, and wires deep underwater. Operating at depths of up to 100 meters, the saw faces: 🏋️♀️ Constant back pressure of ~10 bar 🌊 Saltwater exposure 🌡️ High temperature fluctuations 🌬️ Wind and wave interference 💡 But here's the clever part: the entire cutting process is controlled purely hydraulically, without any electrical components underwater. This not only improves reliability in a corrosive, high-pressure environment—but more importantly, it significantly enhances diver safety. No electronics, no sparks, no compromise. 💪 It’s a perfect example of how hydraulic solutions rise to the toughest challenges—onshore, offshore, or under the sea. Want to know more extreme hydraulic use cases? Let us know in the comments. #funfact #hydraulics #subseaengineering

🎥 𝗧𝗲𝗺𝗯𝘂𝗿𝗼𝗻𝗴 𝗕𝗿𝗶𝗱𝗴𝗲 – 𝗪𝗮𝘁𝗰𝗵 𝘁𝗵𝗲 𝗚𝗮𝗻𝘁𝗿𝘆 𝗮𝘁 𝗪𝗼𝗿𝗸 After Monday’s post, many of you asked for more detail on 𝗵𝗼𝘄 𝘁𝗵𝗲 𝘀𝘆𝘀𝘁𝗲𝗺 𝗮𝗰𝘁𝘂𝗮𝗹𝗹𝘆 𝘄𝗼𝗿𝗸𝗲𝗱. Here’s a short video (courtesy of Daelim-Swee) showing the 𝗲𝗿𝗲𝗰𝘁𝗶𝗼𝗻 𝗼𝗳 𝘁𝗵𝗲 𝘀𝗲𝗰𝗼𝗻𝗱 𝗽𝗮𝗶𝗿 𝗼𝗳 𝟴𝟳𝟬-𝘁𝗼𝗻𝗻𝗲 𝗴𝗶𝗿𝗱𝗲𝗿𝘀 on the 13.65 km marine viaduct. Rather than repeating the engineering specs (you can find them here 👉 https://lnkd.in/p/djMrg3Jf), this clip speaks for itself: 🔹 𝗧𝘄𝗼 𝟱𝟬 𝗺 𝗴𝗶𝗿𝗱𝗲𝗿𝘀 𝗹𝗶𝗳𝘁𝗲𝗱 𝘀𝗶𝗱𝗲 𝗯𝘆 𝘀𝗶𝗱𝗲. 🔹 𝗦𝘁𝗿𝗮𝗻𝗱 𝗷𝗮𝗰𝗸𝘀 𝗹𝗼𝘄𝗲𝗿𝗶𝗻𝗴 𝘁𝗵𝗲𝗺 𝘀𝗺𝗼𝗼𝘁𝗵𝗹𝘆 𝗼𝗻𝘁𝗼 𝗯𝗲𝗮𝗿𝗶𝗻𝗴𝘀. 🔹 𝗖𝗮𝗿𝗲𝗳𝘂𝗹 𝗹𝗼𝗮𝗱 𝘁𝗿𝗮𝗻𝘀𝗳𝗲𝗿 𝗮𝗰𝗵𝗶𝗲𝘃𝗲𝗱 𝘁𝗵𝗿𝗼𝘂𝗴𝗵 𝗮 𝘀𝘁𝗿𝗼𝗸𝗲-𝘀𝘆𝗻𝗰𝗵𝗿𝗼𝗻𝗶𝘀𝗲𝗱 𝗵𝘆𝗱𝗿𝗮𝘂𝗹𝗶𝗰 𝗰𝗼𝗻𝘁𝗿𝗼𝗹 𝘀𝘆𝘀𝘁𝗲𝗺.

BOOM GEARBOX REPLACEMENT | SK2150 SEAKING CRANE 🔧💥 Mission: SK104459 #crane #offshore_oil_rigs https://lnkd.in/d3jB_5_h In this video, you’ll see the complete process of replacing the boom gearbox on a SEAKING SK2150 crane, using part number SK104459. The operation was carried out under challenging conditions and tight deadlines to restore the crane’s functionality. From removing the damaged unit to precisely installing the new gearbox, every step has been professionally documented. One of the most sensitive and critical stages in this repair was gear timing, which had to be set exactly at the 12 o’clock position according to the official documentation. Even the slightest mistake could cause further damage to the gearbox. Due to the size and weight of the components, this job required a 3 to 4-person team and took a considerable amount of time. Unfortunately, this gearbox model is prone to failure. Further technical investigation is needed to identify the root cause: • Was it a material failure? • Is the frame slightly deformed or misaligned? • Does the drum need replacement or correction? • Or is there a recurring issue with the gears themselves that leads to cracking or mechanical breakdown? 🔧 Equipment: SEAKING Crane – Model SK2150 🔩 Replaced Part: Boom Gearbox – Part No. SK104459 🎥 Location: Offshore platform – Real Working Conditions 👉 Don’t forget to like and subscribe for more specialized repair content. #crane #riglife #oilwelldrilling #offshore_oil_rigs #mechanic #maintenance #RigMaintenance #SubseaEngineering #drillingcompany #cranefail #

🎓 #LNGKnowledge How the aluminum spherical tank for Moss type is attached to the ship's steel hull ❓ ✅ The LNG ship Moss type tanks are each supported by a metal skirt from the equatorial ring ⭕, which transmits the weight of the tank and the cargo to the lower hull. The skirt is stiffened in the upper part by horizontal rings ⭕ and the lower part by vertical corrugated stiffeners. ✅ Each tank is covered by a spherical steel tank cover 🔴, the main purpose being for tank and insulation weather protection. The cover also permits control of the hold space atmosphere 💭. The lower edge of each cover is welded to the weather deck, forming a watertight seal 🚧. ✅ A flexible rubber seal is used at the point where the tank dome protrudes out from the cover. 📷 : liquefiedgascarrier More content like this delivered to your inbox❓ Subscribe to My Newsletter for FREE 👉 https://lnkd.in/dQYv_wdN #lng #lngindustry #lngshipping #lngbunkering #gtt #mossdesign #naturalgas #shipping
