ENGINEERING BEYOND THE DRAWING
Designed to work onboard.
Marine House provides comprehensive marine engineering services for newbuild, retrofit, conversion, commercial, government and authorized defence projects.
We combine engineering analysis with practical shipbuilding, installation, inspection, testing and operational experience. Every system is developed for safety, efficiency, maintainability, class compliance and the vessel’s intended mission.
Our multidisciplinary team supports shipowners, shipyards and public-sector organizations throughout the complete project lifecycle.
PropulsionPower to thrust
MachinerySafe, maintainable arrangements
ElectricalGeneration, distribution & control
IntegrationOne coordinated vessel platform
CORE CAPABILITIES
Engineering the complete platform.
Connected disciplines reduce interface risk and ensure the vessel performs as one system.
Machinery Engineering
Engine-room layout, auxiliary machinery, ventilation, exhaust and maintenance access.
Piping Design
Fuel, cooling, bilge, ballast, fire, hydraulic, compressed-air and domestic systems.
Electrical Engineering
Load analysis, generation, distribution, control, navigation and emergency systems.
Automation & Monitoring
Alarm, control, power management and equipment-interface coordination.
System Integration
Space, weight, power, cooling, cabling, control and structural interfaces.
Installation Support
Shipyard coordination, design clarification, inspection and commissioning assistance.
Trials & Verification
Harbour trials, sea trials, performance review and final technical close-out.
PROPULSION SYSTEM ENGINEERING
Matched from engine to propeller.
We design propulsion systems around speed, endurance, bollard pull, payload, draft, manoeuvrability and operating profile. Engine power alone does not determine performance—the complete chain must work together.
01Main-engine power estimation and selection
02Gearbox selection and ratio analysis
03Shaft-line design and alignment
04Propeller selection, design and optimization
05Engine–gearbox–shaft–propeller matching
06Thruster, azimuth and control-system integration
REDESIGN & RE-ENGINEERING
Restore performance. Extend capability.
For vessels with inadequate speed, high fuel consumption, vibration, machinery failure or a changed operating mission.
Repowering
Engine and gearbox replacement, foundation modification, engine-room rearrangement and supporting-system review.
Propeller Redesign
Diameter, pitch, blade area, shaft speed, cavitation, clearance and propulsion matching.
Shaft-Line Modification
Shafting, bearings, alignment, coupling and structural-interface reassessment.
System Conversion
Fuel, cooling, exhaust, ventilation, electrical and control modifications for new machinery.
Performance Review
Speed, thrust, fuel use, operating load, vibration and reliability assessment.
Compliance Reassessment
Stability, structure, class, flag and statutory documentation following modification.
SYSTEM INTEGRATION
Multiple suppliers. One working vessel.
We coordinate equipment and interfaces so propulsion, power, automation, navigation, safety and mission systems operate as one platform.
Interface DefinitionMechanical, electrical, control and data boundaries.
Space & WeightArrangement, access, weight and centre-of-gravity control.
Power CoordinationGeneration, demand, distribution and emergency capacity.
Structural IntegrationFoundations, seating, reinforcement and installation loads.
Cooling & VentilationHeat loads, airflow, piping and environmental requirements.
Testing & CommissioningInspection, interface verification and trial support.
AUTHORIZED DEFENCE PROJECTS
Mission-system integration at platform level.
For authorized government and defence projects, Marine House provides naval-platform engineering for the safe and coordinated integration of approved mission equipment and defence-related systems.
Our role focuses on platform interfaces and engineering coordination in collaboration with the relevant authority, shipyard, approved supplier and original equipment manufacturer, subject to applicable security, export-control and regulatory requirements.
