Visual Inspections
Visual inspections provide an essential first step in assessing the condition of underwater assets, offering both broad and detailed assessments. General Visual Inspections (GVI) provide an overview of structures, identifying obvious issues such as marine growth, corrosion, or damage, while Detailed Visual Inspections (DVI) take a closer look at critical areas, often using high-resolution cameras or measurement tools. These inspections are fundamental for asset monitoring and proactive maintenance planning.
Structural Integrity Assessments
Structural integrity assessments use advanced techniques to evaluate the health of underwater structures and detect potential weaknesses. Ultrasonic Thickness (UT) Measurement assesses metal thickness to monitor corrosion, Flooded Member Detection (FMD) identifies unwanted water ingress in hollow structures, and Alternating Current Field Measurement (ACFM) detects surface and near-surface cracks. These methods ensure that subsea infrastructure remains safe and compliant with industry standards.
Corrosion Protection & Monitoring
Corrosion protection and monitoring help mitigate the risk of material degradation in harsh marine environments. Cathodic Protection (CP) Measurement evaluates the effectiveness of corrosion prevention systems, such as sacrificial anodes and impressed current systems, ensuring the long-term durability of subsea assets. Regular monitoring enables early intervention, reducing repair costs and extending asset lifespans.
Marine Growth & Cleaning Services
Marine growth removal and cleaning services help maintain the efficiency and visibility of underwater structures. Marine Growth Removal eliminates biofouling that can obscure inspections and increase hydrodynamic drag, while Hull Inspection and Cleaning ensures vessels and offshore installations maintain optimal performance and fuel efficiency. These services are vital for reducing maintenance costs and meeting regulatory requirements.
Asset-Specific Inspections
Asset-specific inspections cater to the unique requirements of different industries and structures. Pipeline and Subsea Infrastructure Inspections assess the condition of pipelines, power cables, and offshore equipment, ensuring they operate safely and efficiently. Wind Farm & FPSO Inspections provide targeted assessments of renewable energy and floating production systems, helping operators maintain compliance and maximise operational reliability.
Advanced Inspection & Mapping
Advanced inspection and mapping techniques provide highly detailed, data-driven insights into subsea environments. Subsea Photogrammetry captures precise 3D models of underwater structures, allowing for accurate deformation tracking and structural assessments. Laser Scanning & Point Cloud Mapping generate high-resolution spatial data, supporting maintenance planning and digital twin development for complex subsea assets.
