Shall the machine be operated?



On board submarines, maintenance operations often prove to be delicate and may even last several months. To avoid damage wherever possible, high-precision and rapid maintenance operations must be regularly carried out on large numbers of flanges, valves and pipes.

Where can a SERCO portable machining unit be used?

SERCO-designed and built equipment can be used in confined spaces and demanding environments.
SERCO has designed surfacing and boring machines both for military navy (submarines, aircraft carriers) and merchant navy (cargo vessels, ferries, liners etc.) projects, which cover a very wide range of diameters and can be used for many different applications.

Why prefer SERCO equipment?

Our equipment is reputed for its quality, capabilities, ease of use, light weight and dependability. It is designed for high-precision machining operations. The equipment’s weight and dimensions enable it to be used in difficult to access work areas or under demanding conditions (ionizing radiation, extreme temperatures, saline environments, etc.)

Examples of applications:

SERCO machines are particularly suitable for repairing diesel engines due to the length of their boring stroke and the quality of surface finish they provide. In this way, they contribute to increasing the service life of engines and thereby make significant savings.
