Ballast Water Treatment System

Work Scope

The Ballast Water Treatment System (BWTS) is a crucial system for ensuring compliance with environmental regulations, treating ballast water discharged by vessels during voyages to prevent the spread of invasive species and protect the marine ecosystem. However, due to continuous operation and the challenges posed by the marine environment, regular maintenance and repairs are required. We offer specialized repair services for BWTS based on advanced technology and extensive experience.

The Main Engine Pneumatic Control System plays a crucial role in ensuring the efficient operation and safety of the engine.

Over time, wear or failures in components can occur, making regular overhauls necessary to prevent issues. We provide specialized overhaul services for the Main Engine Pneumatic Control System to ensure the stable and efficient operation of the vessel.
