What We Optimize

• Prime movers: High-efficiency diesel, parallel/serial hybrid, fully electric.
• Transmission line: Gearbox ratios, shaft alignment, couplings, bearings, seals.
• Propulsors: Fixed/variable-pitch propellers, surface finish, cup/pitch matching.
• Controls & software: ECU maps, load curves, power management, AI-based monitoring.
• Hydrodynamics & cooling: Hull/shaft alignment, exhaust backpressure, closed/open loop cooling, anti-fouling.

Our Proven Process
Comprehensive Assessment
Engine/gearbox health, fuel flow, torque curves, vibration & acoustics, thermal scans.
Component Upgrades
High-efficiency props, variable-pitch systems, hybrid/electric packages where appropriate.
Software Calibration
ECU optimization, gear ratio selections, power distribution logic, smart energy management.
Hydrodynamic & Thermal Enhancements
Alignment to reduce turbulence; optimized cooling/exhaust for stable temperatures under load.
Sea Trials & Fine-Tuning
Real-world validation of fuel rate, thrust, and RPM/knots; iterative pitch and mapping tweaks.
Common Problems We Solve

• Excessive Fuel Use

Incorrect AFR, dated ECUs, drag from mismatched props/shafts.

• Vibration & Noise

Misalignment, cavitation, worn bearings/mounts, imbalance.

• Poor Thrust/Speed

Undersized prop area or pitch, inefficient power delivery, hull drag.

• Overheating & Failures

Restricted cooling circuits, degraded lubricants, corroded exhaust/cooling components.

Upgrade Pathways

• Hybrid/Electric Integration for low-noise harbor transits and efficient station-keeping.
• Variable-Pitch Propellers to optimize across speed regimes and sea states.
• Digital Power Management with AI-assisted monitoring for predictive maintenance.
• Advanced Materials (composite props, duplex/stainless components) for strength and corrosion resistance.

Deliverables You Receive

• Baseline & post-optimization performance report (fuel L/h, nm/L, RPM-knots curves).
• Vibration & noise analysis with actionable tolerances.
• ECU map summary, change log, and rollback point.
• Maintenance schedule tuned to your operating profile.

Indicative KPIs We Target

• Fuel efficiency: –8% to –20% (profile-dependent)
• Vibration levels: –20% to –50% in key bands
• Noise footprint: –3 to –8 dB(A) in cabin measurements
• Throttle response: noticeably faster hole-shot and mid-range

(Actual results vary by hull form, displacement, sea state, and existing equipment.)

FAQs
Do I need to switch to hybrid to see savings?
Not necessarily. ECU calibration, alignment, and prop optimization often yield meaningful gains on conventional diesel setups.
Will performance improve at both cruise and top end?
We tune for your real operating envelope. Many owners prefer optimizing at displacement or fast-cruise speeds where hours are logged.
How long does the optimization take?
Typical projects run from a focused 1–2 day calibration and alignment to multi-week upgrade programs when adding hybrid/electric systems.
