Marine Shipping
With bunker costs measured in thousands per day, the difference between complete and incomplete combustion is the difference between profit and loss.
Two marine engines. Same methodology. Certified lab.
NTROPYX® was evaluated at an ISO/IEC 17025 accredited laboratory on two marine diesel reference engines — a Caterpillar C32 ACERT (medium-speed marine diesel) and a Wärtsilä 6RT-flex50 (two-stroke, low-speed, crosshead). Both engines were tested per ISO 8178 Cycle E3 (marine propulsion engines), referenced to MARPOL Annex VI and the IMO NOx Technical Code 2008.

Report GBT104002132 (Caterpillar) and Report GBT104002133 (Wärtsilä), inspection dates March 2026. All testing performed at a CNAS/CMA accredited laboratory per ISO/IEC 17025:2017. Emission measurement per ISO 8178-1 / GB/T 8190.1-2023, test cycle per ISO 8178-4 / GB/T 8190.4-2023 (Cycle E3). Fuel per ISO 8217:2017 / GB/T 17411.From bench to blue water.
One molecular combustion catalyst, one bottle — calibrated to treat the fuel a vessel actually burns, from coastal phinisi to ocean-going container ship.
Real vessel. Real conditions. Bali.
Beyond the laboratory, NTROPYX® was applied aboard M/V KAYRA — a traditional Phinisi vessel moored at Serangan Island, Bali, Indonesia. The test used a full-to-full visual measurement protocol on two identical onboard gensets, followed by a supplementary propulsion test on the main engine.

Two MarelliMotori MJL 200 SA4 alternators (42 kVA continuous) were tested sequentially: first without treatment (baseline), then with NTROPYX®-treated diesel, under the same constant load profile (air conditioning, refrigeration, lighting, ventilation). Fuel level was measured visually via the vessel’s transparent corrugated sight glass tube, using the uniform ridges (spires) as linear measurement units. The vessel’s captain and chief mechanic reported a visible reduction in exhaust smoke during the NTROPYX®-treated runs.

Full-to-full visual measurement protocol, two identical onboard gensets (MarelliMotori MJL 200 SA4, 42 kVA continuous / 46 kVA standby, 400 V / 50 Hz), 12-hour run per phase. Supplementary propulsion test conducted on 23 March 2026 on the main engine (SEAMAN CH900 marine V8). Vessel image courtesy of Kayra Phinisi (kayraphinisi.com).Not an additive. A quantum catalyst.
NTROPYX® is a combustion catalyst — not a fuel additive. It is positioned by Virgo Global Energy SA as a category of its own, distinct from conventional marine fuel treatments available on the bunker market.
NTROPYX is a combustion catalyst, not a fuel additive.
Does not modify the chemistry of the treated fuel.
Chemically undetectable in the treated fuel.
Treatment ratio is calibrated per customer, scaled to volume and operating profile.
EU27 — 44.4 billion litres of bunker fuel. 14% recoverable.
European international maritime bunkers consumed 1 597 296 TJ of liquid fossil fuel in 2023 (Eurostat) — ~44.4 Bn L diesel-equivalent. Heavy fuel oil dominates ocean-going engines (74%), gas oil powers cleaner SECA-zone operations (23%). At the catalyst dose used in the Caterpillar & Wärtsilä bench tests, the recovery scope is unmatched per litre.
Derivation: Eurostat [nrg_bal_c] series INTMARB / siec O4680 (fuel oil 1 221 699 TJ) + O4671XR5220B (gas oil 375 597 TJ) = 1 597 296 TJ. Converted at diesel LHV 36 MJ/L → 44.37 Bn L diesel-equivalent.
INTMARB × O4680 + O4671XR5220B (international maritime bunkers, fuel oil + gas oil) × TJ × 2023. Diesel-equivalent conversion: LHV 36 MJ/L.

Field trial pilots are scoped on a single vessel, with tank-to-tank measurement support and a signed technical annex. Dosage is calibrated to the fuel volume treated and the engine configuration.
