Crossings, protection covers, foundations and support structures are never really one-size-fits-all. That is why we work with project-specific GRP solutions. By adapting each structure to the actual application, it becomes possible to improve installation efficiency and reduce lifecycle burden over time.

Corrosion is not something to be managed later ❌ It should be part of the discussion from the very beginning. Material choice influences service life, maintenance exposure and the long-term burden a structure brings with it. Non-metallic alternatives like GRP offer greater durability and lower maintenance over time. Learn more here 👉 https://csub.com/grp/

In subsea projects, weight affects more than transport 🌊 Lower weight can mean smaller cranes, smaller vessels and fewer installation campaigns offshore. That is why GRP is an attractive choice in applications where reducing offshore installation cost and lifecycle risk is a priority 🥇

In subsea projects, the material itself is only part of the solution. Much of the real value comes from how early the structure is adapted to project requirements, installation method, transport logic, interface conditions and long-term operating demands. That is where co-engineering matters. At CSUB, each structure is developed around the specific project rather than taken off the shelf. Our engineering team works directly with clients on design optimisation, value engineering and fast-track delivery to help ensure the structure is not only technically right, but also practical to fabricate, transport and install.

Substantially above NOK 100 million — and gaining ground in new markets 👏 In Q1, we signed contracts exceeding NOK 100 million in total. Seeing this happen across new markets makes the milestone even more meaningful for us. It shows that we are moving in the right direction and building momentum in new markets alongside our existing ones 🙌

Subsea projects are local in ex*****on, but global in demand 🌍 CSUB operates from its engineering headquarters in Norway, supported by manufacturing capacity across multiple sites and regional production through partners. For offshore clients, that can mean shorter transport distances, greater delivery flexibility and better support across different project regions.

What if your subsea support structures could be installed with smaller cranes, fewer vessel campaigns and better deck utilization — while delivering 50+ years of corrosion-free performance? 🙌 That is what CSUB delivers.

H₂S is one of the most demanding corrosion challenges in oil and gas 😥 In metallic systems, sour-service conditions can increase the risk of cracking, degradation and reduced long-term reliability. That is why material choice becomes especially important in demanding offshore environments.
GRP structures provide a non-metallic alternative, making them particularly relevant in applications where corrosion resistance and long service life are key requirements. Read more about the benefits of GRP: https://csub.com/grp/
