CF Energy brings LNG to where vessels come home: supply in ISO T75 tanks, bunkering by port cluster, safety surveys, MRV data and a financing model that does not require all the capital up front. No gas trading. No retrofit works.
Register a port-cluster pilot →Vietnam has a green-energy transition programme for transport (Decision 876/QĐ-TTg, 2022) and is drafting an emissions-reduction roadmap for its fleet. Dual-fuel engines are already on the market; the hard part is bunkering: where the vessel refuels, how often, and who is responsible if something goes wrong. The three vessel groups below all come home regularly, so those three questions can be answered: back in port on schedule, at a few fixed ports.
High-power vessels on long trips, with fuel the biggest cost of every voyage. Keep the diesel engine, add an LNG dual-fuel system; the fuel saved pays off the equipment over time.
Short routes, fixed schedules, back in port every night, operating in bays that need to stay clean. One bunkering point serves the whole fleet; less smoke, smell and noise right at the passenger pier.
North–South and river–sea routes have fixed end points, so bunkering at both ends is enough. Works alongside Nam Duong's barge fleet and CF Energy's ISO depots at Hai Phong and Cai Mep.
LNG only gets onto a vessel when all five items below run together. LNG supply is the importer's job; the engine is the yard's and the technology supplier's. CF Energy does the three in the middle — the same part it already does for plants on land.
Import terminals, importers and LNG cargo owners.
ISO T75 as mobile buffer or a fixed satellite tank at fishing-port clusters, tourist piers and coastal ports.
Truck-to-ship, ISO-to-ship or from a quayside station; safety procedure, ESD, gas detection, exclusion zone.
Retrofit and maintenance of the dual-fuel system — technology partners and certified yards under registry rules.
GasTwin™ logs diesel, LNG, engine hours and route per voyage; reports to owners, banks and regulators.
No one-size retrofit for every vessel, and no station built before there are enough vessels. Each port cluster goes through five steps; each step ends with a document that owners, banks and regulators can all see.
Length, power, operating days, diesel consumption, engine age, distance to the bunkering point, ability to repay.
Vessel and engine files, tank space, ventilation, fire safety; actual diesel used per trip.
Bunkering location, ISO/satellite-tank configuration, bunkering procedure; retrofit file prepared by the partner and submitted to the registry.
Leak test, pressure test, ESD test; monitor at least one full operating cycle.
Assess safety, economics and environment; expand cluster by cluster where it works, upgrade the station once volume proves it.
How much LNG helps must be measured on board, not estimated from factors. Unburned methane (methane slip) must be counted, otherwise the emissions figure looks better than reality. GasTwin™ logs the fields below per voyage and exports reports in one format.
| Group | Metrics tracked | Used for |
|---|---|---|
| Fuel | Diesel and LNG per voyage / period; actual substitution rate | Net saving; reconciliation against the sharing contract |
| Operations | Engine hours, engine load, route, number of bunkerings, bunkering time | Normalise consumption intensity; schedule bunkering |
| Safety | Leak alarms, fire incidents, procedure compliance, downtime | Condition for expanding the cluster |
| Environment | CO₂e by an approved method; NOx / SOx / PM where measurable; methane slip | Green-credit and carbon-credit files |
| Supply chain | LNG fulfilment rate, logistics cost per tonne, minimum stock | Station upgrade decision |
ISO tanks, the tractor fleet, port operators, river–sea barges, the measurement platform — CF Group already has all of it to serve plants on land. Taking it to vessels is extra use, not new investment.
A tank supplying a plant by day can sit as buffer at a fishing port by night. The ISO depots at Hai Phong and Cai Mep are two ready starting points for the coastal route.
The port crane operator and the barge operator are both group companies — the bunkering procedure is written with the people who will actually do it.
The AI/IoT monitoring platform exists; GasTwin™ only adds vessel data fields, not a new system.

No. Retrofit design and installation are done by technology partners and certified yards under registry rules. CF Energy surveys, secures LNG supply, bunkers, handles safety at the transfer point and MRV data. Not doing the on-board part is what lets CF Energy work with every technology supplier.
Best suited are vessels long enough to fit the tank and safety equipment, with high power, many operating days a year, high diesel consumption, and regularly calling at a port cluster where bunkering can be organised. Exact thresholds are set from each vessel's real data after survey, not from a fixed template.
It depends on the configuration: transfer from an ISO or road tanker needs a hard standing for vehicle access, an exclusion zone, dedicated connection equipment and trained operators; a fixed quayside station shortens the time and serves the whole fleet. Bunkering time is fixed in the technical plan for each cluster.
CF Energy is responsible for the procedure and equipment at the transfer point — pre-transfer checks, exclusion zone, emergency stop, gas detection. The on-board fuel system falls under the registry-certified design. The boundary of responsibility is written into the contract and the coordination procedure.
Yes, but it must be measured on board: actual diesel and LNG used, engine hours, and unburned methane. GasTwin™ logs per voyage and reports by a method approved by the competent authority. CF Energy does not publish benefits from theoretical factors.
Not necessarily. Bunkering and storage equipment can be invested by CF Energy or a partner under an ESCO or equipment-lease model; the on-board retrofit can access green credit with the MRV file. The exact structure depends on the number of vessels in the cluster and the actual savings data.
