Matching a marine set to a vessel, not to a catalogue

Marine buyers come to this page for two reasons. Either they are specifying a new build and need an engine that will be supported in the yards and ports the vessel will actually use, or they are replacing an engine and need a set that fits the mounts, sea-water piping and exhaust already on board. In both cases the deciding factors are serviceability along the route and physical fit in the engine room, not the highest available rating.

We assemble marine generating sets on Weichai marine diesel engines, and the model is confirmed against the vessel's electrical load and available space before production begins.

Engine platformWeichai marine diesel
Usual output window12 kW to 500 kW in the marine programme
Engine modelsConfirmed per vessel, including models in the CW6200 family

InstallationBase frame and flexible mounts arranged for the hull position

Specification sheet for a Weichai marine generating set

Protection	Engine protection and shut-down arrangement specified with the panel
Spares	Consumables for this engine family are distributed through the marine supply chain in Asia, Africa and the Middle East

Packing	Strong wooden case with waterproof cloth
Typical duty	Fishing vessels, workboats and tugs, cargo and utility craft, passenger vessels

Weichai marine diesel generating set on a steel base frame with radiator and control panel — A set from this series on its base frame. Engine, alternator and control panel are assembled as one unit so the assembly can be lifted into the engine room and secured as a whole.

Points that decide a marine selection

Engine model is confirmed, not assumed. Vessels asking for a Weichai marine engine often arrive with a model number in mind; we check the model against the electrical load and the space available before quoting.
Service reach matters more at sea than on land. The engine family is served through the marine supply chain in the regions the vessel operates in, which is why consumables availability is part of the selection.
The mount and piping arrangement follows the hull. Replacement sets are matched to the existing mounts and sea-water circuit wherever the arrangement allows.
Continuous hotel and deck loads suit a matched alternator. The alternator frame is chosen for the load the vessel carries for hours at a time, not for a peak figure.
Protection works when nobody is watching. Shut-down and alarm settings are configured with the panel, which matters on a manned engine room with an unattended watch.
Access decides the largest possible unit. Hatch openings and the lifting path are checked before the rating is finally agreed.

The manufacturer

Jiangsu Qingzhiteng Power Equipment Co., Ltd manufactures diesel and gas generator sets in Yangzhou, Jiangsu. The marine programme runs from 12 kW to 500 kW alongside an inland diesel range of 3 kVA to 3000 kVA, and the same works produces sets with ATS, parallel systems, container units and remote-monitoring configurations. The company exports to more than 80 countries on five continents.

Assembly and release of a marine set

Electrical load, engine room dimensions and the access route are agreed and the engine model is fixed.
Engine and alternator are received and checked against that specification.
The set is assembled on its base frame and aligned.
Sea-water circuit, heat exchanger and exhaust arrangement are fitted and tested.
Panel wiring and protection settings are completed and checked.
The set is run on the test bench and its electrical and protection settings are verified.
The unit is cased with waterproof cloth and shipped with its documentation.

Vessels supplied

Fishing vessels, Southeast Asia

Operators wanted an engine family that could be serviced in the ports they use, so consumables availability was part of the selection along with the electrical load.

Utility and workboat, Africa

A replacement set had to fit existing mounts and the sea-water circuit already installed, so the arrangement was agreed with the yard before assembly.

Passenger craft, Middle East

Hotel and deck loads ran for long periods, so the alternator frame was selected for the continuous load and the panel was placed at the operating station.

Marine questions buyers ask

Which Weichai marine engine model suits my vessel?

Send the electrical load on board, the engine room dimensions and the access route. If you already have a model number in mind, include it, and we will confirm whether it matches the load and the space before quoting.

Can the sea-water circuit on board be reused?

Where the pipe sizes, strainer position and discharge are suitable for the new set, the heat exchanger arrangement is matched to the existing circuit. Send the arrangement and it will be checked against the selected engine.

Are spares available where the vessel operates?

Consumables for this engine family circulate through the marine supply chain in Asia, Africa and the Middle East. On an enquiry we can state the service items involved so the operator can plan local stock.

What protection is provided for unattended engine rooms?

Engine protection and shut-down settings are specified with the control panel. Tell us how the engine room is manned and what alarms you need, and the panel arrangement will be set accordingly.

What are the MOQ, lead time and payment terms?

These depend on the rating, quantity, destination and payment method and are given in the quotation. Send the vessel details and the port and we will quote on that basis.

For the alternative marine platform see the Cummins marine series, and for shore installations the land-based range; the full product range lists the remaining programmes.

Send the vessel and engine room details

Tell us the electrical load on board, the existing engine model if there is one, the engine room dimensions and hatch opening, the sea-water and exhaust connections, the voltage and frequency, the quantity and the destination port. With that we can confirm the engine model and the installation arrangement.
