  • Electrical diagrams – Accurate single-line and schematic diagrams

  • Switchboard design – Custom MV and LV switchboard engineering

  • Ex-equipment design – Safe design for explosion-proof environments (ATEX/IECEx zones)

  • Control and monitoring systems – Automation, alarms, and performance monitoring

📡 Navigation and Communication Engineering

  • Bridge system design – Integration of all major navigation systems:
    Gyro, Radar, ECDIS, Autopilot, GPS, Echosounder, AIS, IBS, GMDSS, Speed Log

  • Antenna arrangement design – Optimized layout for performance and regulatory compliance

  • Commissioning and system testing – Ensuring reliable functionality from day one

All engineering work is carried out in accordance with the latest IMO and classification society regulations, using industry-standard CAD and simulation tools.

Steel and piping works

Offshore & Marine Services OÜ offers extensive expertise in steel and piping works for marine and offshore repair, upgrade, and conversion projects. Our team is highly skilled in handling a wide range of pipe systems and materials, including carbon steel, stainless steel, copper, and glass fiber-reinforced epoxy (GRE).

We carry out installations for systems such as:

  • Ballast water systems

  • Seawater cooling

  • Potable water

  • Firefighting systems

  • Gland and flushing systems (dredgers)

  • Black and grey water systems

  • In-tank cargo pipelines

  • Ballast water treatment systems

  • Scrubber systems

Together with our trusted partners, we also perform a wide range of steel works — from simple structural modifications to the complex fabrication and installation of major ship elements, including:

  • Hull sections and blocks

  • Foundations and platforms

  • Radar masts and drilling derricks

  • Monorails and steel outfitting components

🔧 Corrosion Protection and Coating Solutions

Operating in demanding marine environments requires materials to perform near their limits. One of the key challenges is corrosion of steel structures and fasteners. To mitigate this risk, we ensure all external components are treated with high-performance protective coatings.

Scrubber Installation

Scrubber systems — or exhaust gas cleaning systems — are designed to reduce sulfur oxide (SOₓ) emissions from ship engines and boilers, ensuring compliance with international environmental regulations.

Offshore & Marine Services OÜ offers full-scope solutions for the selection, design, and installation of scrubber systems. We help shipowners identify and implement the most efficient system based on vessel type, space limitations, and operational needs.

Our services include:

  • Onboard inspection and feasibility studies

  • Review and verification of existing technical documentation

  • Plug-and-play installation concept for minimal downtime

  • Precise onboard measurements and site evaluation

  • 3D CAD modelling of the planned installation

  • Classification and workshop documentation

  • Structural strength calculations

  • Vibration and stability analysis

  • Full onboard installation and integration

We ensure that every solution is tailored, technically sound, and fully certified — from concept to commissioning.

Ballast Water Treatment System

Ballast water often contains a diverse mix of marine organisms, including plants, animals, and microorganisms transported across ecosystems. When discharged in a different region, these non-native species can survive, spread, and disrupt local ecosystems — sometimes causing significant environmental and economic damage.

To prevent this, international maritime regulations require the installation of Ballast Water Treatment Systems (BWTS).

Offshore & Marine Services OÜ provides complete turn-key BWTS solutions tailored to your vessel and operational needs.

Our services include:

  • Verification and review of existing technical documentation

  • On-board surveys and system feasibility checks

  • Conceptual and technical design

  • Support in selecting the appropriate BWTS and manufacturer

  • Preparation of classification documentation for approval

  • Development of detailed workshop documentation

  • Full onboard installation and integration

We ensure compliance with IMO and USCG standards and deliver reliable solutions from planning to commissioning.
