Shipyard Machinery: Manufacturing Processes and Quality Control

Industry Standards in Naval Equipment Construction

When a shipyard orders a conveyor belt or a refrigeration system, it is not buying a catalog: it is buying a process. Every piece of equipment that leaves our plant goes through a defined sequence of cutting, welding, machining, assembly, and testing. There are no shortcuts.

Manufacturing begins with certified marine steel plates. They are cut with high-definition plasma and visually inspected before moving to welding. All critical joints — those that will bear dynamic loads at sea — are inspected with ultrasound and magnetic particle testing. Porosity and inclusions are not accepted.

Shaft and gear machining is done on CNC lathes with tolerances in the hundredths. Each part is measured with a probe and recorded in a manufacturing report. If a dimension is not within range, the part is rejected and re-machined. It is not adjusted during assembly.

Final assembly takes place on a test bench. There, the motors, gearboxes, and drums are mounted, and the assembly is subjected to a load equivalent to 110% of the nominal load for four continuous hours. Temperatures, vibrations, and consumption are measured. Only if everything is within parameters is the equipment released for shipment.

That is the standard. Not because a manual says so, but because a piece of equipment that fails at sea is not a logistical inconvenience: it is an operational and economic risk. That is why every client who arrives with technical questions receives concrete answers, not promises.
