The application
Define the duty at every ship interface.
A shipboard cold line, a fuel-system skid and a bunkering connection can require different operators, end connections and inspection records. We work from the system specification to define the valve assembly, its control interfaces and the documentation required by the project and classification society.
Bunkering & transfer
Emergency shut-off and release equipment selected as part of the transfer-system specification.
Non-return & control
Axial and dual-plate checks, screw-down non-return selection and modulating globe assemblies.
Selection essentials
What defines the right configuration?
- System duty
- Fuel, cargo, bunkering or vapour-line function and operating sequence.
- Controls
- Utility, shutdown logic, feedback and required operating times.
- Environment
- Orientation, enclosure requirements, access and marine exposure.
- Project approval
- Classification society, design standard, witness tests and documentation.
