First HVO-blend supply reported on 1 September; vessel fuel verification under way

Participation source

Toyo and NX Shoji report HVO-blend bunkering for DCM8 at Nagoya Port. The case puts fuel approval, witnessed blending and delivery records alongside the vessel's ground-improvement performance.

Nagoya DCM8 HVO-blend programme identities: DCM8 deep-mixing vessel, Tomac operator, NX Shoji supplier; the DCM6 FAME campaign is a separate 2025 trial.

Project anatomy

Contract scope and delivery roles

Client / authority
Toyo Construction Co., Ltd.
Delivery parties
Tomac: operator of Toyo group ground-improvement vessel DCM8., NX Shoji: HVO-blend fuel supplier and approval-route participant.
Contract route
Company marine-fuel verification programme, announced by Toyo and supplier NX Shoji on 26 October. No external works competition is identified in the programme announcements.
Execution window
First supply on 1 September 2026 at Nagoya Port; the companies report verification begun. A final test duration or result date is not specified.
Works package
HVO blended with conventional diesel and supplied to deep-mixing vessel DCM8 working on marine ground improvement at Nagoya Port. The named wider civil contract is not disclosed.
Marine interfaces
Fuel batch specification, tank inventory and engine hours need to connect to the treatment log and accepted ground-improvement output. Soil, treatment depth, standby and re-treatment affect fuel consumption per completed cubic metre.
Commercial evidence boundary
Delivered fuel price, blend proportion and documented lifecycle factor need to be assessed against recorded consumption over a comparable work period. Quantified savings and costs remain undisclosed in the announcements.

Evidence gap

What remains unverified

Outstanding evidence

  • Batch specification, blend proportion and lifecycle-emissions basis
  • DCM8 tank readings, operating hours and accepted treatment volume
  • Engine verification findings and repeated-supply availability
