Green Technology

3C Metal offers clients turnkey solutions and crucial integration services. We provide all aspects of the retrofit process, from initial assessment and design to installation, testing, and certification.

Exploring green retrofit turnkey solutions for merchant vessels is a forward-thinking approach to improving the environmental sustainability of maritime transport. This involves upgrading existing ships with newer, greener technologies to reduce emissions, increase energy efficiency, and comply with international regulations. Our capabilities include, but are not limited to, the following projects: energy efficiency solutions including VFD-controlled electrical power optimization for pumps and fans; emissions reduction technologies including CO2 capturing and ballast water treatment system (BWTS) integrations; hull modifications and hydrodynamic efficiency; waste heat recovery systems; and solar and wind power integration.

3C Metal is your dedicated partner with experience in maritime retrofit projects, a good understanding of international rules and regulations, and access to the latest green technologies.


3C Metal is a trusted green technology retrofit partner, facilitating everything from surveys, feasibility studies, 3D laser scanning, engineering, pre-fabrication, installation, electrical integration and assistance with commissioning. We don’t believe a vessel should be taken off hire during retrofit projects, and we work with vessel owners and ship managers to plan projects accordingly, with vessels continuing operation as normal while the retrofit installation takes place.

We have a highly-experienced deployment team on hand, ready to carry out retrofit projects smoothly and efficiently. 3C Metal's installation capabilities include retrofits onboard container ships, bulk carriers, cruise ships, RO-ROs, drillships, semi-submersibles and super yachts, with UV-systems, pasteurization systems, electro chlorination, chemical injection systems. 3C Metal's experienced team will ensure there are minimal disruptions to the vessel's operations.
