Free from the influence, guidance, or control of others Jaisu Shipping Company's spare parts and machining needs are independent, self-contained, self-reliant. The company maintains a 24/7 workshop and repair facility with a crew and personnel strength of 300 people.

Starting from the bare minimum needs of machining custom size nuts and bolts the company has machined and constructed propellers up to 3 meters in diameter. Recent works include manufacturing of a grab with 4 cum grab capacity in less than 10 days time. The spares department holds spares for every engine part and the engine as a whole. Thus cutting down on the downtime for maintenance in an efficient manner.
