No two sites—or load tests—are the same. That’s why we don’t rely on a single method. ✅ Static Load Testing (ASTM D1143 / D3689) – compression & tension, delivering precise data for axial performance. ✅ Dynamic Load Testing – fast, efficient, and effective when time matters. ✅ Bi-Directional Load Testing – ideal for deep shafts and large loads, eliminating the need for massive reaction frames. ✅ Lateral Load Testing – critical for serviceability and structural performance. With over 100 load tests completed each year, FTG designs and executes the right program for your project—whether it’s drilled shafts, auger cast piles, micropiles, driven piles, anchors, or tiebacks. Our goal: maximize efficiency, reduce cost, and deliver confidence in your foundation. 🔗 Learn more: https://lnkd.in/e_iAzNPw #FTGbuilds #Engineering #Construction #LoadTesting

Dropcell Surveys: The CP Health Check If you want to know whether your CP system is really protecting your asset, a dropcell survey is a quick and easy fail-safe method. Here’s how it works: • A calibrated reference electrode is lowered adjacent to the steel structure (platform jacket, vessel hull, harbour wall, etc.). • The structure cathodic protection potential is recorded and compared to historical and future readings. • Any deviation from the generally accepted -800 mV to -1100 mV protection range (Ag/AgCl/sw) is flagged and assessed. For more complex geometry structures, topside dropcell surveys can still provide reliable average potentials. But if readings are more positive than -800 mV, there’s a risk of under-protected areas, especially in complex nodes or enclosed spaces. That’s when we recommend a contact potential survey via ROV. Subsea Corrosion Pro Tip: Average potential readings can hide localised risks. Always investigate low readings before they become expensive problems. At Subsea Corrosion Ltd, our survey methods combine precision measurements, expert interpretation, and robust reporting so you can make informed maintenance decisions. Whether your CP system is ICCP or sacrificial anode-based, a regular dropcell survey is your first line of defence against unexpected failures. #offshoreinspection #marineengineering #cathodicprotection #corrosionprevention #subseaengineering

Bidirectional Static Load Testing (BDSLT) is a proven method for assessing the axial capacity of deep #foundations, particularly bored piles. Unlike conventional top-down static load tests, #BDSLT mobilizes both end bearing and shaft resistance simultaneously in opposite directions. This eliminates the need for external reaction systems while enabling higher test loads with reduced site constraints. ⚠️ Limitations → Requires accurate interpretation to combine upward and downward resistances → Test setup must be integrated early in the construction schedule → Hydraulic jack remains embedded in the pile and is generally non-recoverable → Does not directly test pile head performance or load transfer at the pile top 📊 Typical Instrumentation Includes → hydraulic jacks for bidirectional load application → Strain gauges to capture axial stress distribution → Displacement sensors (LVDTs or dial gauges) to measure movement → Tell-tales for multi-depth displacement monitoring → Data loggers for continuous data acquisition and analysis 🏗️ Use Cases → Large-diameter bored piles for bridges, towers, and high-rise foundations → Projects with limited space where traditional reaction setups are impractical → Testing ultra-high capacity foundations beyond the scope of top-down methods → Sites with geotechnical variability requiring separation of skin and base resistance 📹: GRL 🔄: Useful?

🔍 Beyond Spot UT: Elevating Pressure Vessel Inspections with B-Scan Technology When it comes to critical equipment like pressure vessels, relying solely on traditional spot ultrasonic thickness readings on grids (as some inspection scopes still suggest) can leave blind spots. At F&G Technologies, we leverage advanced B-Scan Ultrasonic Inspection with the Scorpion Crawler, enabling: 
✅ High-precision mapping of wall thickness across the entire surface
✅ Early detection of pitting corrosion and gradual wall thinning
✅ A more reliable, data-driven diagnosis compared to isolated spot checks
✅ Significant savings in scaffolding costs
✅ Greatly reduced operational risks by avoiding the need for working at height
✅ Enhanced safety and asset integrity for your most critical operations With this approach, operators gain a far clearer picture of asset health, ensuring informed decisions and extending the lifecycle of their equipment. 📍 We operate nationwide across all U.S. states without limitations. 📧 contact@fygtechnologies.com

Dynamic Load Test of Piles (DLT) Dynamic load testing is a quick and reliable method to check pile capacity and integrity. A hammer is dropped on the pile head, and sensors record force and velocity. The test helps to: ✅ Verify load-carrying capacity ✅ Check pile integrity ✅ Save time compared to static load test Widely used in high-rise & infrastructure projects for faster foundation quality assurance. #PileFoundation #DynamicLoadTest #ConstructionQuality #CivilEngineering

Did you know that a containerized solution onboard a ship or offshore unit falls under the same classification rules as decks and bulkheads, and all transits need to be type approved? With Roxtec seals, you can ensure certified protection all while being openable and adaptable to cables and pipes of different sizes. They provide fire protection, pressure ratings and solutions for Ex and shielded areas. The penetration seals prevent humidity inside deckhouses, shelters and containers, resist corrosion and withstand vibration while providing excellent cable retention to extend cable and system lifetime. As an integrator, you gain a competitive advantage by delivering completely protected containers that help ensuring operational reliability.

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

🔹 Construction & Working of 3-Phase Induction Motor ⚡ Construction A 3-phase induction motor mainly consists of two parts: 1️⃣ Stator – A stationary part made of laminated steel core and three-phase winding placed in slots. It produces a rotating magnetic field (RMF) when 3-phase supply is given. 2️⃣ Rotor – The rotating part placed inside the stator. Two types are common: Squirrel Cage Rotor (simple, rugged, widely used) Slip Ring Rotor (used for high starting torque applications) Both parts are separated by a small air gap. ⚡ Working Principle When a 3-phase supply is given to the stator winding, a rotating magnetic field (RMF) is produced. This RMF cuts the rotor conductors → EMF induced in the rotor (Faraday’s Law). Since the rotor is short-circuited, current flows in the rotor conductors. According to Lorentz force law, interaction between rotor current and stator field produces torque, causing the rotor to rotate in the direction of RMF. The rotor speed is always slightly less than synchronous speed (called slip). ⚡ Key Features ✅ Simple & rugged construction ✅ Low maintenance ✅ Widely used in industries (pumps, fans, conveyors, compressors, etc.) #electrical #machine #inductionmotoar
