On a recent voyage in 2024, an Indian-flagged LPG carrier transporting 15,400 tonnes of liquefied petroleum gas (LPG) successfully sailed out of the Strait of Hormuz, a critical maritime chokepoint. This passage underscores India’s heavy reliance on secure sea lanes for energy imports, particularly through the Strait, which facilitates about 20% of global petroleum trade. The event highlights the intersection of India’s domestic maritime regulatory framework, international maritime law, and the geopolitical risks inherent in energy supply routes.

Legal Framework Governing Indian-Flagged Vessels and Maritime Zones

The Merchant Shipping Act, 1958 defines the registration and operation of Indian-flagged ships, with Section 4 specifying criteria for an 'Indian ship'. The Maritime Zones of India (Regulation of Fishing by Foreign Vessels) Act, 1981 governs India’s Exclusive Economic Zone (EEZ), ensuring sovereign rights over marine resources. Internationally, the United Nations Convention on the Law of the Sea (UNCLOS), 1982 regulates navigation rights through international straits like Hormuz, particularly under Part II (Territorial Sea and Contiguous Zone) and Part V (EEZ). The Indian Ports Act, 1908 regulates port operations critical for LPG handling, while the Petroleum and Natural Gas Regulatory Board Act, 2006 (Section 11) mandates safety standards for LPG transport.

• Merchant Shipping Act, 1958: Registration, ownership, and safety of Indian ships
• Maritime Zones of India Act, 1981: Regulation of foreign vessels in India’s EEZ
• UNCLOS, 1982: Right of transit passage through international straits, including Hormuz
• Indian Ports Act, 1908: Port operations and cargo handling regulations
• PNGRB Act, 2006: Safety and standards for LPG transport

Economic Significance of the Strait of Hormuz for India’s Energy Security

India imports approximately 85% of its crude oil through the Strait of Hormuz, making it a vital artery for energy security. In FY 2023, LPG imports via maritime routes stood at around 7.5 million tonnes, with the Indian-flagged vessel’s 15,400 tonnes representing a fraction of this volume but symbolizing broader import dependencies. The country’s energy import bill reached $180 billion in FY 2023, reflecting the scale of reliance on imported hydrocarbons. Disruptions in Hormuz could escalate LPG prices, impacting household energy costs and industrial feedstock prices, thereby influencing inflation and GDP growth.

• India’s LPG import volume: 7.5 million tonnes in FY 2023 (PPAC)
• Energy import bill: $180 billion in FY 2023 (Economic Survey 2023-24)
• 85% of crude oil imports transit through Strait of Hormuz (MoPNG Annual Report 2023-24)
• Maritime incidents in Hormuz increased by 30% from 2020-2023 (International Maritime Bureau)

Institutional Roles in Maritime Energy Security

The Directorate General of Shipping (DGS) administers ship registration and maritime safety standards. The Ministry of Petroleum and Natural Gas (MoPNG) formulates policies and oversees energy imports. The Indian Coast Guard (ICG) ensures maritime security and protection of shipping lanes, particularly in sensitive areas like Hormuz. Globally, the International Maritime Organization (IMO) sets safety and security standards, while the Petroleum Planning & Analysis Cell (PPAC) provides critical data on petroleum imports and consumption.

• DGS: Registration, certification, and safety compliance of Indian ships
• MoPNG: Energy import policy and strategic planning
• ICG: Maritime security, anti-piracy, and protection of sea lanes
• IMO: International maritime safety and security standards
• PPAC: Data analytics and monitoring of petroleum supply chains

Strategic Vulnerabilities and Policy Gaps

India’s overdependence on the Strait of Hormuz exposes it to geopolitical risks, including maritime security threats and supply disruptions. Despite the increase in maritime incidents by 30% between 2020 and 2023, India’s diversification of energy import routes remains limited. The absence of significant pipeline infrastructure or alternative maritime routes constrains India’s ability to mitigate chokepoint risks. Current energy security policies do not adequately address these vulnerabilities, leaving India exposed to price shocks and supply uncertainties.

• High geopolitical risk due to chokepoint dependence
• Limited alternative import routes or domestic substitutes
• Insufficient infrastructure for LNG and pipeline diversification
• Need for enhanced maritime security coordination and diplomacy

Significance and Way Forward

The passage of the Indian-flagged LPG carrier through the Strait of Hormuz is emblematic of India’s strategic energy dependencies. Strengthening maritime security through the Indian Coast Guard and Navy cooperation is essential. India must accelerate diversification by investing in LNG terminals, pipeline connectivity, and strategic petroleum reserves. Diplomatic engagement with Gulf and Central Asian countries can open alternative supply corridors. Robust implementation of maritime safety laws and adherence to UNCLOS provisions will safeguard navigation rights and energy imports.

• Enhance maritime security presence in chokepoints
• Invest in LNG infrastructure and pipeline projects
• Develop strategic petroleum reserves to buffer supply shocks
• Leverage diplomatic channels for alternative supply routes
• Strengthen compliance with international maritime law (UNCLOS)
