Subsea Crossings and Bridges for Pipelines and Umbilicals

CSUB designs and fabricates GRP subsea crossings and bridges for pipelines and umbilicals where controlled separation, reliable support and practical offshore installation are required. Lightweight, non-metallic composite construction helps reduce handling complexity, limit corrosion-related lifecycle exposure and support project-specific crossing solutions for demanding subsea environments.

CSUB’s crossings and bridges are designed for locations where subsea pipelines, umbilicals or cables must cross other assets or seabed features under controlled conditions. Each structure is developed to suit the actual route, interface requirements, support geometry and installation method, helping operators and contractors manage crossings with a practical and durable subsea solution.

Lower Installation Cost and Offshore Complexity
Lightweight GRP structures help simplify transport, lifting and offshore handling compared with heavier traditional alternatives. This can support more efficient installation planning, reduced handling complexity and lower offshore installation cost.

Project-Specific Design for Pipelines and Umbilicals
Crossing structures can be engineered to suit pipeline and umbilical configuration, route conditions, support height and friction interface requirements. This helps project teams implement crossing solutions that are adapted to actual field and installation constraints rather than standardised one-size-fits-all designs.

Corrosion-Free Composite Performance
CSUB’s non-metallic composite crossing structures eliminate metallic corrosion risk and provide durable long-term subsea performance. This helps reduce lifecycle maintenance exposure while supporting reliable operation in demanding offshore environments.

CSUB crossings and bridges are developed with a strong focus on execution offshore. Low weight, fabrication flexibility and project-specific adaptation help support efficient loadout, handling and installation while limiting unnecessary seabed intervention where project conditions allow. Optional low-friction interface solutions can also be incorporated where required to suit installation and operational needs.

CSUB supports customers with engineering input, structural assessment and project documentation to help reduce technical and procurement risk. By combining design development with composite fabrication expertise, CSUB helps operators, contractors and subsea suppliers implement crossing solutions that are practical to install and aligned with project requirements.
