Overview of Services
The Group made enormous progress in more recent areas of business, such as the construction of cross-country pipelines and high-pressure systems for the petrochemical, fertilizer, and refinery industries. Aban inevitably entered the powerful fields of power generating and drilling.
The biggest private participant in India’s offshore drilling market is ABAN. It is a member of the Aban Group and was marketed by Aban Constructions Private Limited in association with the Gulf of Mexico offshore drilling firm Chiles Offshore Inc., USA. The company offers offshore drilling and production services for oil and gas exploration, development, and production. It owns and runs drill ships, a floating production complex called “Tahara,” and seven offshore drilling rigs.
Scale of Operations
With its headquarters located in Mumbai, Maharashtra, India, Abban Offshore is a prominent supplier of offshore support services to the oil and gas sector. With a significant presence along the western coast, particularly the Mumbai High region, the corporation mostly operates in Indian offshore waters.
Anchor handling tug supply vessels, platform supply vessels, and multipurpose support vessels are all part of the diverse fleet of offshore support vessels that Abban Offshore oversees. The company’s position in India’s offshore energy services industry has been strengthened by the steady expansion of its fleet and operational capabilities over time.
