Construction support survey
Construction support experience across more than ten offshore projects, including the world’s largest single offshore wind farm.
Spectrum provides construction support survey services to support offshore installation, engineering, and verification activities throughout the construction phase of marine infrastructure projects. Drawing on more than 20 years of experience across offshore energy and infrastructure developments—including support for some of the world’s largest offshore wind projects—our team delivers accurate, dependable survey data that enables safe, efficient, and well-informed construction operations.
By combining advanced geophysical survey techniques, subsea inspection capabilities, and high-precision positioning systems, Spectrum delivers timely and reliable datasets that support installation accuracy, asset integrity, and construction quality assurance. Our integrated approach helps reduce uncertainty, verify compliance with design specifications, and minimise risk throughout the offshore construction process.
Our construction support survey capabilities include:
Catenary imaging
High-resolution seabed imaging to verify cable and pipeline catenary configuration during installation.
This supports installation monitoring and ensures assets transition correctly from suspended installation to final seabed laydown.
High-Voltage (HV) cable and pipeline depth of burial
Geophysical survey techniques are used to measure burial depth and confirm that installed cables and pipelines meet engineering and protection requirements.
Accurate burial verification supports compliance with installation specifications and reduces exposure risk.
Boulder detection and removal support
Pre- and post-installation surveys to identify seabed obstructions that may pose risks to cable installation or infrastructure stability.
Survey data supports safe boulder clearance operations and confirms that routes are free from hazards.
Scour monitoring
Repeat surveys are required to detect and monitor seabed scour around foundations, cables, and subsea structures.
Monitoring seabed change helps assess structural stability and informs maintenance or mitigation strategies where required.
Cable monitoring
Post-installation inspection and monitoring surveys provide ongoing assessment of cable condition, exposure, and seabed interaction.
These surveys help identify areas of potential risk and support long-term asset integrity management.
Real-Time Kinematic (RTK) positioning service setup and support
Spectrum provides RTK positioning services to support offshore installation activities requiring high-accuracy GNSS positioning.
