Flange facing and X-Y milling are very common activities for us. We usually carry them out
- either during the new building stage, on behalf of the shipyard, during equipment installation or
- during service of the vessel or plant whenever plane surfaces were found damaged or distorted and are in need of remachining
Examples of work that we performed during during equipment installation includes landing surfaces of FPSO turrets, LNG tank covers, thruster mounting surfaces and pedestal bearings. Common repair jobs include the skimming of heat exchange cover surfaces and the remachining of surfaces after welding repair to eliminate distortion.
For circular flanges, the maximum size that we are able to machine with high accuracy is around 5,000 mm diameter. For rectangular or square shaped surfaces limits lie at around 10,000 mm x 8,000 mm.
Most of the flange facing and Y-Y milling machines that we use were designed and built by ourselves. These machines are very advanced and very compact to reduce freight costs and to be able to work in very tight places.
We always check and adjust the accuracy of our machining activities by laser. In some cases the lasers are even built into our machines.
