Rotterdam and Northern Europe
Hybrid-electric propulsion built for measurable fuel savings.
Engineering-led marine power systems for commercial vessels — designed to reduce fuel burn, improve redundancy, and simplify compliance across newbuild and retrofit projects.
Purpose-built propulsion systems for demanding fleets
Engineering hybrid propulsion for real vessels.
Tidal Forge Marine Systems focuses on the technical realities of commercial shipping: power balance, duty cycles, space constraints, class requirements, and installation downtime.
Our process combines propulsion analysis, electrical architecture, energy storage integration, control logic, and operational modeling to shape systems that perform on the water, not just on paper.
Whether the project is a newbuild specification or a retrofit conversion, we align the propulsion strategy with fuel economics, reliability targets, and vessel mission profiles.
Performance
Fuel savings and reliability for commercial vessels.
Headline metrics for owners and technical teams who need hard numbers before a retrofit or newbuild decision. Indicative ranges depend on route profile, sea state, hotel load, and the vessel’s duty cycle.
Typical fuel reduction target
Measured against duty cycles with variable load, port maneuvering, and partial-load cruising.
Hybrid assist envelope
Designed to absorb peaks, support transients, and keep engines closer to efficient operating bands.
Preferred generator loading
Energy management is tuned to stabilize generator operation, reduce cycling, and improve reserve margin.
Indicative storage range
Selected to fit retrofit space, endurance goals, redundancy strategy, and classification constraints.
Process
How the system is engineered.
A clear delivery path from vessel analysis to commissioning, built for shipyard coordination and owner approval.
-
01
Profile the vessel duty cycle.
We review route data, loading patterns, hotel demand, maneuvering behavior, and downtime constraints to identify where hybrid architecture adds value.
Deliverable: technical feasibility brief and duty-cycle summary.
-
02
Model propulsion and electrical architecture.
Candidate system topologies are simulated for fuel use, reserve margin, redundancy, and operating cost under representative sea states and route segments.
Deliverable: power balance, architecture options, and indicative performance range.
-
03
Select batteries, motors, generators, and controls.
Component selection is aligned to installation envelope, cooling strategy, class requirements, and the vessel’s maintenance profile.
Deliverable: interface matrix, equipment schedule, and control philosophy.
-
04
Validate integration, documentation, and sea-trial readiness.
We close the loop with control logic validation, commissioning checks, owner handover materials, and sea-trial tuning against the agreed baseline.
Deliverable: commissioning pack and trial report template.
Solutions
Three propulsion architectures.
Three options matched to vessel profile, mission profile, and retrofit constraints. Each solution includes indicative performance ranges and integration considerations.
Hybrid assist
Peak shaving and maneuvering control.
For vessels with variable loads and frequent maneuvering, batteries absorb peaks while engines remain in efficient bands.
Diesel engines
Primary generation
Energy management
Load balancing and control logic
Motor / battery bank
Assist, regenerate, and smooth transients
Integration focus
Suited to ferries, workboats, and multipurpose cargo vessels where maneuvering, peak demand, and partial-load operation are the main cost drivers.
- Absorbs short power spikes without over-sizing the main engines.
- Improves low-speed control and response in port approaches.
- Reduces generator cycling and smooths transient loads.
- Creates redundancy for critical hotel and propulsion systems.
Proof
Retrofit case study: measurable gains on a working vessel.
A vessel retrofit example shows how engineering choices translate into operational results.
A commercial vessel operating on mixed coastal routes was selected for a hybrid-electric retrofit to improve efficiency at partial load and reduce engine hours.
The final architecture combined battery-assisted peak shaving, optimized generator scheduling, and a new energy management system tuned to the vessel’s duty cycle.
Sea trial results showed smoother load transitions, lower specific fuel use in port approach conditions, and improved operator confidence through built-in redundancy.
“The performance model gave us a clear business case before we committed to retrofit design.”
Compliance and validation
Engineering proof is built into the delivery process.
Each project includes performance modeling, safety review, control strategy validation, and documentation support for class and owner review.
We map the integration pathway across propulsion, switchboards, batteries, cooling, and monitoring systems to reduce installation risk. Commissioning closes the loop with measured baselines, control tuning, and operator handover materials tailored to the vessel.
Class-facing documentation
Submission-ready packs aligned to DNV, Lloyd’s Register, ABS, and Bureau Veritas review formats.
Validation workflow
FMEA inputs, control logic checks, alarm philosophy, and commissioning test points tracked from concept to trial.
Operational readiness
Handover materials shaped for crews, superintendents, and shipyard teams so the vessel enters service with clarity.
Reporting support
Documentation structure suitable for emissions tracking, efficiency proof, and owner reporting.
“Their performance model gave us a clear business case before we committed to retrofit design.”
“The integration package was precise enough for our yard to plan installation without rework.”
“We needed redundancy, not just efficiency. Their architecture delivered both.”
Delivery
Project timeline from concept to sea trial.
An implementation schedule that helps shipyards and owners plan procurement, yard time, and testing windows.
Vessel profile, route data, operational constraints, and stakeholder goals are captured and translated into a feasibility brief.
We compare propulsion architectures, confirm the operating-mode matrix, and shape the technical direction around the mission profile.
Interface control, equipment sizing, documentation, and class-facing drawings are prepared for yard coordination.
Procurement support, installation guidance, and change control keep the project aligned with schedule and budget.
Control tuning, baseline checks, sea-trial validation, and operator handover close the loop before entry into service.
