DAS Offshore Limited is one of India's most experienced offshore fabrication and engineering companies, incorporated in 1987 and operating for over 35 years across the upstream oil & gas, infrastructure and shipbuilding sectors. Headquartered in Navi Mumbai, Maharashtra, the company owns and operates Rohini Yard — a dedicated waterfront fabrication facility on India's west coast — from which it delivers large-scale offshore structural fabrication, EPC contracting and industrial construction services to clients across India and internationally.
Over three decades, DAS Offshore Limited has grown from a specialist offshore fabrication contractor into a fully diversified engineering company. The company’s core strength remains in upstream hydrocarbon — encompassing offshore platform fabrication, module and skid fabrication, topside packages, jacket pile fabrication and brownfield engineering — while its Infrastructure Division delivers marine structures, barge construction, bridge superstructures and RDSO approved railway fabrication. This breadth of capability, supported by ISO 9001:2015, ISO 14001:2015 and OHSAS 18001:2007 certifications, positions DAS Offshore Limited as a trusted partner for complex, large-scale engineering projects.
DAS Offshore Limited is governed by a board of industry technocrats with deep expertise in the hydrocarbon and infrastructure sectors. The company’s three operating divisions — Oil & Gas, Infrastructure and Rohini Yard — function with dedicated teams, specialist equipment and full in-house fabrication capabilities. Two subsidiary companies, DAS Instrumentation Pvt. Ltd and Changbhale Engineering & Services Pvt. Ltd, further extend the group’s capabilities in Electrical & Instrumentation and NDT services respectively, enabling DAS Offshore Limited to deliver fully integrated project solutions under a single contract framework.
