Trident is not a distributor with a price list. Every motor that leaves Dordrecht is the result of an engineering review, duty, geometry, electrical environment, installation context. Whether the brief is a new build, a retrofit or an emergency replacement, the engineering work is the work.
From a photograph of an existing motor plate, we reconstruct the full electrical and mechanical specification. We have the back-catalogue, the design experience and the workshop record to do this for almost every European-built submersible motor of the last forty years.
Every motor can be built exactly to specification. Trident engineers the machine around the existing installation: foundation, shaft end, cable routing and connection dimensions are taken over one to one, so the vessel or plant itself does not change.
A retrofit motor has to slot into a vessel that was not designed around it. Mounting bolts, shaft height, terminal position, cooling connections, every interface gets engineered for drop-in fit, even when the internal motor design changes significantly.
Fixed-speed motors retrofitted with inverter-rated insulation, terminal shielding and bearing protection. Where the vessel is also moving to inverter drive, we coordinate the motor design with the drive specification, du/dt limits, switching frequency, cable length.
Final finishing and testing in the Dordrecht workshop. Every motor goes through a no-load test, a load test, an insulation resistance check and a high-voltage withstand test before it leaves the building. FAT to your specification, optional witness test.
On-site commissioning support available globally. A Trident engineer joins your team for the installation and the start-up, verifies the protection signal routing, confirms the drive parameters and signs off the commissioning report.
Every motor is delivered with a complete as-built documentation package. Test certificate, as-built dimensional drawing, electrical schematic, protector wiring diagram, recommended spares list, maintenance schedule. Issued in the language and format your class society requires.
The TKBS series is engineered, finished and tested in our workshop in Dordrecht. Van Bodegraven has been engineering electric motors continuously since 1898. The current capability envelope.
A workshop is not a marketing claim. It is a set of physical capacities, what you can crane, what you can coat, what you can test. The Dordrecht facility runs continuously from inbound inspection through final test.
For projects outside our workshop envelope, Trident draws on a network of partner facilities across the Netherlands and the wider EU.
Trident motors are engineered per project after order placement. The technical documentation goes to your engineers for approval, and manufacturing starts only after that written approval. Six stages, one approval point.
Application and requirements reviewed. Trident confirms the proposed motor concept is feasible before you commit.
You place the order. Final requirements and application data go to Trident Engineering, and all input is checked before design starts.
The motor is designed for your application and the driven machine: electrical design, shaft and coupling, flange and bolt pattern, monitoring, materials.
The technical package goes to your engineers for review. Comments are worked in; written approval closes the design. No manufacturing before approval.
Production, assembly, electrical and mechanical testing, quality control and final inspection.
Documentation completed, test results available, units released for dispatch.
For complex projects, capacity upgrades, deep sea duty, class-society approvals, the conversation starts with the Trident engineering desk.
