BROCHURE DATA

The WASP industry is growing 40× by 2030, yet no platform provides vessel-specific, physics-grounded performance intelligence. Operators are flying blind.

01
Pre-Install Blindness
Vendors provide generic polar diagrams — no model for specific vessel geometry, actual routes, or loading conditions.
±40% UNCERTAIN ESTIMATES
02
Post-Install Waste
WASP devices are rarely optimally operated. Rotor speed, TWA, engine load interactions are too complex for manual control.
20–40% SAVINGS UNREALISED
03
Fleet Strategy Gap
Mixed-fleet owners can't prioritise which vessels benefit most from which WASP technology without vessel-specific models.
SUBOPTIMAL CAPEX ALLOCATION
04
Regulatory Exposure
IMO CII tightens annually to 2030. EU ETS costs are live now. Owners must document actual performance improvement.
NON-COMPLIANCE = PORT BANS
Our Approach

WHERE PHYSICS
MEETS INTELLIGENCE.

Most WASP tools give you generic estimates. OpSimNAV gives you your vessel, your route, your answer — grounded in real physics, delivered in milliseconds.

Physics You Can Trust
Built on high-fidelity CFD and wind tunnel data — not statistical guesses. Every insight is grounded in the real aerodynamics of your vessel.
Intelligence at Operational Speed
Our AI surrogate delivers answers in under 10 milliseconds — fast enough to guide real decisions in real time, as conditions evolve.
Hardware-Agnostic by Design
Rotor Sails, Airfoil Wings, mixed fleets — OpSimNAV works across all WASP technologies and all OEMs. One platform, every device.
WHY OPSIMNAV
Every WASP manufacturer gives you hardware with a basic control system. OpSimNAV is the intelligence layer above all of them — the only platform that is physics-informed, vessel-specific, and works across every OEM.
OEM SOFTWARE
Hardware-locked control dashboards. Works only with their own product. No cross-fleet, no physics model.
GENERIC VOYAGE SW
General fleet analytics. Not WASP-aware. Cannot model wind propulsion physics or predict sail performance.
OPSIMNAV
Physics-first. OEM-agnostic. Vessel-specific. The only platform built exclusively for wind propulsion intelligence.

THREE TOOLS.
ONE MISSION.

From the moment you consider WASP to the day you outperform every benchmark — a purpose-built tool for each stage of that journey.

ASSESSMENT
WASPassess
🔍
Know the real opportunity before you commit. A vessel-specific, physics-informed feasibility study — so every WASP investment decision is backed by evidence, not brochure data.
FLEET STRATEGY
WASPfleet
🛳
Turn your entire fleet into a competitive advantage. Portfolio-level intelligence that shows where the highest returns are, tracks CII compliance, and reports to regulators automatically.
All three tools run on the same physics-informed AI engine. One model of your vessel. Three ways to use it.

Why OpSimNAV

THE ONLY PLATFORM
BUILT FOR THE
WHOLE INDUSTRY.

The WASP industry is growing fast — and every hardware manufacturer is focused on building world-class wind propulsion systems. None of them provides the vessel-specific, physics-grounded intelligence layer that operators need to realise the full value of those systems.

OpSimNAV is not a WASP hardware competitor. We are the software intelligence layer that sits above all of them — OEM-agnostic, physics-first, and designed entirely around what operators actually need.

Physics-informed — explainable, not a black box
CFD and wind tunnel data fused into AI that encodes real aerodynamics. Outputs engineers can understand and verify — not just numbers to accept on faith.
OEM-agnostic across all WASP types
Rotor sails, airfoil wings, suction sails — OpSimNAV models them all. Mixed fleets get a single unified intelligence layer regardless of which hardware is installed.
The entire WASP lifecycle — one platform
Pre-installation ROI to real-time control to fleet CII compliance. One physics engine, three products, every stage of the journey.
22%
Additional fuel saving vs unoptimised WASP
The gap between vessels operating hardware without real-time physics intelligence and those using OpSimNAV — the opportunity we exist to close.
<10ms
Physics-informed surrogate inference
A complete vessel-specific WASP performance prediction — thrust vector, fuel saving, CII impact — in under 10 milliseconds. Operational speed, physics accuracy.
