Protection Structures for Subsea Production and Processing Equipment

CSUB specializes in GRP protection structures for subsea production and processing equipment. Lightweight, corrosion-free composite construction helps reduce installation burden, simplify offshore handling and support long-term subsea performance. Our solutions are developed for applications where protection, access and practical offshore operability are critical.

CSUB offers a patented GRP Single Well Protection Structure designed to protect subsea wellheads while maintaining practical offshore access. Compared with traditional steel alternatives, the lightweight composite design can help reduce deck-space demand, ease crane and handling constraints, and support more efficient installation and recovery.

The structure is developed with overtrawlable geometry, self-penetrating skirts for stabilization, large openings for full ROV accessibility and top hatches for intervention and operational access. This gives operators and contractors a protection structure that combines robust protection with practical offshore operability.

CSUB also supplies GRP structural and protective components for subsea processing applications where low weight, corrosion resistance and practical access are important design drivers. As supplier of GRP structural components for the NOV Seabox™ Water Treatment System, CSUB contributes from detail design to delivery for a subsea processing application, without acting as the system OEM.

Our portfolio also includes project-specific GRP structures for subsea oil and chemical storage applications, demonstrating how composite solutions can be used to protect equipment and support offshore operations in demanding subsea environments.

Lower Installation Burden

Low-weight GRP structures can help reduce deck-space demand, crane limitations and offshore handling complexity compared with heavier traditional steel alternatives.

Lower Lifecycle Burden

Corrosion-free composite construction supports long subsea service life and helps reduce maintenance exposure over time.

Protection with Practical Access

CSUB’s structures are developed to protect critical equipment while maintaining ROV access, intervention openings and practical offshore operability.

CSUB combines subsea structure expertise with GRP fabrication capability to develop protection structures aligned with project-specific equipment, access requirements and offshore constraints. From design development to fabrication and delivery, we support operators, contractors and equipment providers with practical offshore solutions for subsea production and processing equipment.
