Aban Offshore
An Indian offshore drilling contractor that provides drilling rigs and related services to oil and gas companies.
Last updated August 31, 2026
Overview
Aban Offshore is an Indian offshore drilling services company headquartered in Chennai. Established in 1986, it developed around the provision, chartering and operation of offshore drilling rigs for oil and gas exploration and production companies. Its customer base has been particularly associated with Indian oil companies, including Oil and Natural Gas Corporation, while the group also pursued international offshore activity. The company’s principal operating capability has been the deployment of offshore drilling units, including jack-up rigs, under contracts with energy producers. Such contracts generally provide customers with access to drilling capacity, rig crews and associated operational support without requiring them to own the drilling unit. The business is capital intensive and depends heavily on rig utilization, contract day rates, maintenance costs, financing conditions and the level of exploration and development spending by oil and gas companies. Aban expanded beyond its original offshore drilling focus through activities connected with onshore drilling, construction, wind energy, power generation, information-technology-enabled services, hotels and resorts, tea plantations and marketing. Offshore drilling nevertheless remained the company’s defining business identity and the main basis for its recognition as a listed Indian energy-services enterprise. The company was affected by the severe downturn in the global offshore drilling market, which reduced demand and pressured rig rates and utilization. Publicly reported information also records substantial debt-related stress, legal proceedings connected with loan defaults, disputes involving customs treatment of an offshore vessel and a sanctions-related enforcement matter involving a Singapore subsidiary. In August 2022, Aban Offshore reached a one-time settlement with Central Bank of India and paid the outstanding principal identified in the settlement, after which the bank withdrew its insolvency application before the National Company Law Tribunal. The available reference material reports a consolidated net loss of ₹1,972.53 crore for 2021. No reliable current operating profile, active fleet list or current corporate website is established in the supplied sources. Accordingly, Aban Offshore’s present status as an independent going concern requires verification rather than being assumed from its historical listing or former operating scale.
History
Aban Offshore was established in India in 1986 and became associated with the country’s offshore drilling and oilfield-services sector. Its core business developed around supplying drilling units and related operational services to oil and gas exploration and production companies. The company’s historical identity was closely linked to offshore drilling contracts, especially work for Indian oil companies such as Oil and Natural Gas Corporation. The operating model relied on owning, chartering and managing offshore drilling units. Jack-up rigs were an important part of the company’s reported fleet and service offering. These rigs are used in relatively shallow offshore environments and can be moved between contract locations, making their economic value dependent on availability, technical condition, utilization and prevailing day rates. Aban’s business therefore combined industrial operations with significant balance-sheet exposure to equipment purchases, maintenance, debt financing and long-term charter commitments. As it expanded, the group pursued business interests beyond offshore drilling. Reference material associates the wider group with construction, onshore drilling, wind energy, power generation, information-technology-enabled services, hotels and resorts, tea plantations and marketing. Aban Offshore also developed activity outside India, making it an Indian multinational offshore drilling-services provider rather than a purely domestic contractor. The offshore drilling industry subsequently entered a difficult cycle. Lower oil prices, reduced exploration budgets, excess rig capacity and declining utilization placed pressure on contractors across the sector. Aban Offshore experienced related operational and financial difficulties, including debt stress and restructuring-related problems. The available sources report a consolidated net loss of ₹1,972.53 crore for 2021, but do not provide enough information to reconstruct a complete year-by-year financial history or establish the current condition of every asset and legal entity. The company was also involved in several regulatory and legal matters. In 2015, the Directorate of Revenue Intelligence seized the Aban-ICE vessel over allegations concerning deployment beyond its authorized contractual zone. Aban challenged the customs duties and penalties, arguing that amended government essentiality certificates supported its position. Separately, a Singapore subsidiary became subject to a U.S. sanctions enforcement matter in 2017 involving the alleged unauthorized re-export of U.S.-origin goods to Iran. The matter was resolved through an OFAC settlement and payment of a civil monetary penalty. Debt problems later led Central Bank of India to file an insolvency application under Section 7 of the Insolvency and Bankruptcy Code. In August 2022, Aban Offshore reached a one-time settlement with the bank, paying ₹121.78 crore in outstanding principal. The bank then withdrew its application before the National Company Law Tribunal. This settlement reduced the immediate insolvency proceeding, but the supplied material does not establish whether Aban Offshore subsequently restored a substantial operating fleet, continued as an independent going concern or underwent further corporate changes.
