SLOFEC® FloorScanner

he SLOFEC® FloorScanner is an advanced electromagnetic tank floor inspection system that uses Saturated Low Frequency Eddy Current technology to detect corrosion and wall loss in storage tank floors — even through coatings.

How It Works

The system uses eddy current technique with an array of sensors fixed in a carrier driven along the surface. It detects surface cracks even under non-conductive coatings. The scanner employs 8-sensor arrays covering both weld zones and heat-affected zones, with spring-loaded holders that follow weld contours for precise detection.

Key Applications

• Tank Floor Mappind

ACFM Eddy Current

Our ACFM (Alternating Current Field Measurement) system provides reliable, repeatable crack detection on any type of welding with maximum coating of 5mm — no surface cleaning required. Built-in 5MP camera captures on-site documentation.

How It Works

ACFM works by introducing an alternating current into the surface of the component being inspected. When a crack is present, the current flow is disturbed, and the resulting changes in the magnetic field above the surface are detected by sensors. This allows accurate measurement of crack length and depth without removing coatings.

Key Applications

• Weld inspection
• Painted and coated structures
• Cranes and towers
• Refinery piping and vessels
• Bridges and infrastructure
• Topside onshore/offshore structures

FOCUS+ Guided Wave Testing

The FOCUS+ unit uses guided wave technology to screen long lengths of pipe for anomalies. Unlike conventional UT which tests only the area beneath the transducer, guided waves can inspect entire pipe segments rapidly — then focus in on problem areas with precision.

How It Works

The computer-controlled, battery-operated unit uses an integrated pump for collar inflation around the pipe. Guided waves propagate along the pipe wall, reflecting from corrosion, erosion or other anomalies. The FOCUS+ software automatically performs most setup functions and enables one-click focusing on localized areas of interest.

Key Applications

• Long-range pipe screening
• Corrosion detection under supports
• Road crossing pipe inspection
• Insulated pipe assessment
• Offshore riser inspection

Robotic Blasting & Surface Prep

Our robotic blasting system provides environmentally friendly, zero-discharge coating removal and surface preparation. The fully contained system uses vacuum and magnets to adhere to any steel surface orientation — vertical, horizontal, or inverted.

How It Works

The robot utilizes ultra-high pressure water jetting (up to 55,000 PSI) to remove coatings while maintaining 100% containment of water, paint and corrosion debris. Magnetic and vacuum adhesion allows the unit to operate on any surface orientation. Wireless remote control enables safe operation from a distance.

Key Applications

• Storage tank surface preparation
• Vessel coating removal
• Pipeline maintenance
• Offshore structure refurbishment
• Industrial painting preparation

INTERGRIID®

INTERGRIID is a Digital Condition-Based Management (DCBM) platform for offshore structural integrity management. It combines measurement, monitoring, engineering models, and risk analysis to support evidence-based decisions for offshore assets.

How It Works

INTERGRIID works by transforming offshore asset integrity management from periodic, assumption-based inspections into a continuous, evidence-based monitoring system. Instead of relying solely on engineering calculations, it continuously measures how a platform actually behaves and uses that information to guide inspection, maintenance, and life-extension decisions. Overall Workflow 1. Measure The first step is to measure the platform's actual structural behaviour offshore using sensors. The system collects data such as: Accelerometer readings Structural strain Metocean (environmental) conditions The goal is to understand how the structure behaves under real operating conditions rather than relying only on theoretical models. 2. Compare The measured behaviour is then compared against the engineering design model. Specifically, the system compares: Measured structural response Design models created in tools such as SACS and SESAM This determines whether the platform is behaving as engineers expected. 3. Rank INTERGRIID ranks every offshore asset according to its measured risk. Instead of inspecting all platforms on a fixed schedule, assets with the greatest evidenced risk receive priority attention. 4. Act Finally, the measured evidence is used to drive operational decisions, including: Risk-Based Inspection (RBI) Inspection planning Maintenance Asset life-extension decisions The presentation emphasizes that actions are based on measured evidence rather than conservative assumptions. Three Core Capabilities The presentation explains that the platform is built around three complementary capabilities. IG-Insight (Structural Health Check) A short-term measurement campaign that: Measures dynamic structural condition Verifies engineering models Supports pre-life-extension assessments Performs post-event inspections Its purpose is to answer: "What does the platform look like today?" IG-Monitor (Structural Health Monitoring) This component installs permanent sensors on the offshore platform. It continuously: Monitors structural trends Detects changes in stiffness Detects changes in structural mass Detects abnormal dynamic responses Builds a live digital twin Its purpose is to answer: "Where is the platform heading?" IG-Assure (Dynamic Risk Assessment) The measured structural behaviour is converted into engineering risk metrics. It calculates: Structural Reliability Index (SRI) Probability of Failure (PoF) Dynamic Risk-Based Inspection recommendations Its purpose is to answer: "What does the measured risk mean?" The Technical Principle A central idea in the presentation is that every offshore platform behaves like a mass–stiffness system. Changes in either the platform's stiffness or mass alter its natural frequency, making natural frequency an indicator of structural health. The presentation notes that trends in natural frequency can reveal changes caused by factors such as marine growth, scour, soil changes, corrosion, or section loss. The system therefore monitors structural behaviour rather than waiting for visible damage. Model vs Reality Engineering Model Predicts how the platform should behave using geometry, soil, loading, and mass assumptions. Measured Monitoring Shows how the platform is actually behaving under real environmental and operational conditions. If the measured and modelled behaviour align, engineers gain confidence in continued safe operation. If they diverge, the system recommends investigation, model updates, Risk-Based Inspection (RBI) updates, and targeted inspections. End-to-End Process The technology's complete process, as described in the presentation, can be summarized as: Install sensors or use existing inspection data. Collect real-time structural measurements. Analyse structural behaviour. Compare measured behaviour with engineering models. Detect structural changes and anomalies. Calculate reliability and probability of failure. Rank assets by measured risk. Update inspection schedules and maintenance plans. Support life-extension decisions with evidence rather than assumptions.
