Our Advantages

A comprehensive approach, proven expertise and reliable partnership at every stage of the project.

Comprehensive Approach

Full-cycle services — from engineering and inspection through to construction and handover. One contractor for every stage.We have an extensive experience and successfully completed more than 10 000 projects.

Specialized Underwater Expertise

Reliable inspection, repair and reinforcement of underwater structures — carried out by certified divers with 30+ years of experience.

Extensive Marine Experience

Proven track record in demanding marine environments — port infrastructure, coastal and hydraulic structures.

Flexible Solutions

Tailored approach to every project — non-standard and technically complex hydraulic and marine structures.

Vessel Inspection Without Drydocking

To ensure proper safety conditions for passengers, vessel crew and cargo — and to extend a vessel's lifecycle — periodical surveys of the underwater part are essential.

  • Underwater inspection

    Full hull survey by certified divers per classification society requirements no drydock needed.

  • Hull cleaning

    Removal of marine growth and biofouling to restore hydrodynamic performance and reduce fuel consumption.

  • Propeller-rudder system cleaning

    Cleaning and inspection of propeller blades, rudder and shaft components to restore propulsion efficiency.

  • Ultrasonic thickness measurement

    Non-destructive hull plating measurement detecting corrosion and confirming structural integrity.
