Goltens Retrofit / Upgrade / Repower Enhanced
Decarbonization and Emissions Reduction Retrofits
Turnkey EPC retrofits for SOx scrubbers, SCR, waste heat recovery (ORC), air lubrication, propeller optimization, route optimization, emissions monitoring and shaft generators.
Description
Goltens Green Technologies delivers full EPC turnkey retrofit solutions, from feasibility studies and 3D scanning through engineering design, procurement, prefabrication, installation, commissioning and lifecycle support. The division was launched in 2010, has six global centers of excellence and reports 2,000+ completed projects.
Key features
- SOx scrubbers and SCR systems (IMO Tier III NOx compliance), independent of technology supplier
- Waste heat recovery: Organic Rankine Cycle (ORC) systems converting heat from engines, exhaust gases, cooling water or steam into electricity or mechanical power
- Ship resistance reduction: bulbous bow replacement, slow steaming and air lubrication (microbubble, air layer and air cavity)
- Route optimization with Qtagg EcoPilot, Marine Technologies Smart Ship and C-Connect, and Navalt Oceanix
- Propeller optimization: caps, nozzles/ducts and other technologies
- Emissions monitoring: Continuous Emissions Monitoring Systems with EMSYS and Protea
- Shaft generators: retrofit projects with WE Tech Solutions
Applications
Emissions compliance and energy-efficiency upgrades on existing vessels of all types.
