Engineering-Led Integration for Commercial Vessels


Thompson Marine’s in-house engineering team designs, integrates, and commissions complete CAT® power and Berg Propulsion systems for commercial vessels. The team manages the entire project lifecycle, from initial analysis and system specification through installation, sea trial support, and commissioning. Thompson Marine’s engineering team stays engaged from initial design through installation and commissioning, working in close coordination with those teams to ensure project knowledge carries through every phase.

Complete System Packaging and Integration

Thompson Marine engineers complete, installation-ready packages that go beyond engines and thrusters. Every package includes gears, pumps, filters, and custom piping, documented with detailed engine room layouts, wiring schematics, and mechanical installation drawings specific to the installation.

Mechanical and Electrical Integration

The primary focus of Thompson Marine’s engineering work is integrating complex power and propulsion systems into the vessel’s existing or new structure, ensuring all mechanical connections, electrical systems, and controls work in concert.

Control and Monitoring System Design

Thompson Marine designs and builds control and monitoring systems calibrated to the operational requirements of the vessel and the power systems installed, providing reliable command and clear visibility of all machinery.

Power Package Design and Build

Complete power packages are engineered, fabricated, and documented in-house, covering electrical integration, mechanical integration, and all supporting systems.

New Power and Propulsion Systems

Thompson Marine provides the engineering foundation for new vessel builds, ensuring CAT marine engines and Berg Propulsion systems are specified, integrated, and installed for optimal performance from the first day of commercial service. Engineering analysis for new builds includes:

Piping system calculations covering exhaust backpressure, fuel and air supply, and cooling water flow

Engine room air supply and exhaust sizing to maintain ideal operating conditions

Vibration isolation analysis

Six-degrees-of-motion studies

Finite Element Analysis

Shaft whirling analysis

Electrical schematics and wiring diagrams

Repowers and Retrofits: Modern Power for Proven Hulls

Fleet Modernization Planning

Thompson Marine works directly with fleet managers to develop repower and retrofit plans aligned with maintenance windows and operational schedules.

Legacy System Integration

Thompson Marine’s engineering team ensures new Caterpillar engines and Berg Propulsion systems work seamlessly with existing controls and auxiliary equipment, delivering modern efficiency without a full vessel overhaul.

Berg Propulsion Integration


Berg Propulsion systems offer native control architecture capable of managing mechanical, direct-drive electric, and battery-hybrid power sources within a single platform. Thompson Marine’s engineering team configures Berg’s control system to the specific requirements of the vessel and the power plant, without complex third-party add-ons or external automation layers.

Hybrid Propulsion Systems

Thompson Marine designs and integrates hybrid propulsion systems combining Caterpillar main engines with Berg Z-drives, electric motors, variable frequency drives, and a Thompson Marine-developed control interface. These systems reduce main engine hours, lower fuel consumption, and establish the architecture for future battery integration without requiring a second round of major upgrades.
