Dual-Fuel RoRo on a 38% EV-Mix Route
By Field Engineering · February 12, 2026 · 6 min read
A new-build dual-fuel PCTC carrying a 38% BEV cargo mix on a trans-Pacific route. The highest EV percentage we have run continuous coverage on.
A new-build dual-fuel PCTC on a trans-Pacific route, carrying a 38% BEV mix in its standard manifest — well above the 30% internal review threshold most operators now use. The detection layer ran continuously over four full round-trip voyages.
Why the deck environment is harder
- Higher absolute EV count per deck — more candidate event sources.
- Dual-fuel main engines produce different deck thermal profiles than conventional propulsion.
- Tropical mid-passage sailings push ambient and solar gain into worst-case envelopes.

Round-trip voyages of continuous coverage
"On the third voyage we caught a forward-deck BEV with a slow underbody drift. By the time we located the vehicle and isolated it, the cell coherence had already escalated to red. That is the lead time we were paying for."— Chief Officer (operator NDA)

The EV-Percentage Tipping Point Nobody Wants to Quote
Public statements from operators talk about "mixed cargo" — internally the conversation is about a hard percentage above which sailings should be re-routed. That number is moving.
