Fabrication Services

Rotary has a total of 6 fabrication workshops spanning across key regions in Middle East and Southeast Asia. Apart from providing shop fabrication support to our EPCM services, the workshops also undertake standalone fabrication projects for various multinational and local clients.

The 6 workshops occupy a combined total of more than 30 hectares, capable of more than 1.2 million dB of piping, 9,000 tonnes of structural steel, 42,000 tonnes of tankage works per year.



One-stop solution is provided to satisfy all your requirements. Our main core specializations are:
- Tankage pre-fabrication
- Structure fabrication
- Piping fabrication
- Pressure vessel fabrication

SS, CS, AS and all metals are designed, purchased and fabricated in accordance with international standards such as ASME, TEMA, ASTM, API, NACE etc.

Instead of outsourcing, we prefer to keep all ancillary activities in-house in view to upkeep the highest standards and efficiency we have always maintained. Within the confines of our workshops, we have our own blasting, painting, NDT, inspection yards that complement our core services.

Our Services – Tankage

Tanks are the heart and soul of each terminal which explains our profound expertise in this area as well.

Our shops are equipped with plate rolling machines, CNC cutters, AVW & AGW to size and shape plates as per your project requirements. We are also able to execute fabrication for different types of materials which include cryogenic, spherical, pressure vessel tanks etc.

When required, we will be able to fabricate and assemble smaller-sized tanks in the workshops, before transferring them to the worksite that will allow for swift ground installation.
