SEAFIRST MARINE LIMITED has built up a very professional and experienced team which specializes in all kinds of in-situ machining. These equipments are designed by our own company and are one of the most efficient tools on for ship repair.

In-situ milling for flange surface

Our engineers can carry out in-situ milling for flange surface of deck cranes and other equipments. The machining is needed especially after new flange is welded to the pedestal or if there is any deformation on these flange surfaces. The work range can be up to 5 meters diameter and our equipment can be disassembled into small parts so it is easy to transfer for various jobs at different ports.

Machining Range: Φ 1250mm-5000mm
