Ballast Water
Treatment Systems (BWTS)

Independent BWTS services Engineering and turnkey installation of ballast water treatment systems

At SYM Naval, we provide independent engineering and installation services for ballast water treatment systems (BWTS), supporting shipowners throughout the entire project lifecycle. From system selection and engineering to onboard installation and commissioning, we deliver compliant and efficient BWTS solutions tailored to each vessel’s technical and operational requirements.

Our teams work both afloat and in dry dock, including installations carried out during navigation to minimise vessel downtime. With in-house engineering, 3D scanning and digital modelling capabilities, and worldwide operational support from our strategic bases, we ensure safe, optimised and class-approved BWTS installations for commercial vessels operating globally.

Independent selection

Technical advice without ties to any manufacturer, ensuring the most suitable BWTS solution for each vessel and operational profile.

3D design

In-house engineering, 3D scanning and digital layouts to validate feasibility, optimise integration and streamline approvals.

Turnkey installation

Complete BWTS installation services including prefabrication, onboard integration, commissioning and class approval.

Afloat & dry dock

BWTS installations carried out afloat, during navigation or in dry dock, minimising downtime and operational impact.

Proven engineering expertiseBWTS projects delivered worldwide

With extensive experience in ballast water treatment system projects, SYM Naval supports shipowners worldwide from concept to execution. Operating from our strategic bases in Barcelona and Santo Domingo, we deliver BWTS installations for a wide range of commercial vessels, coordinating closely with owners, yards, class societies and onboard crews.

Our teams are used to working under real operational conditions, carrying out BWTS installations afloat, during navigation or in dry dock. This practical approach allows us to reduce downtime, optimise execution schedules and ensure fully compliant installations adapted to each vessel’s design and trading pattern.

How we workEfficient BWTS project execution

Each ballast water treatment system project is approached with a clear focus on feasibility, planning and execution efficiency. Our in-house engineering team develops tailored solutions based on the vessel’s layout, operational constraints and regulatory requirements, ensuring smooth integration of the BWTS into existing onboard systems.

Through 3D scanning, digital modelling and prefabrication, we reduce onboard work and optimise installation timelines. This methodology allows us to adapt the level of intervention to each project, whether during scheduled dry dockings or through carefully planned installations carried out while the vessel remains operational.
