Exploration, extraction, and transport of hydrocarbons via maritime routes
The oil and gas industry is a cornerstone of the global economy, providing the primary energy sources that power transport, manufacturing, and countless everyday activities. Within the maritime sphere, it covers the entire offshore lifecycle – from geophysical surveys and seismic mapping to exploration drilling, production, storage, and transport. Operations may take place hundreds of kilometers offshore, using fixed platforms, semi-submersibles, jack-ups, drillships, and floating production units.
Once extracted, hydrocarbons are processed and transported via specialized vessels such as VLCCs (Very Large Crude Carriers), FPSOs (Floating Production, Storage, and Offloading units), and LNG carriers that maintain gas at cryogenic temperatures. The industry is deeply interconnected with maritime law, port logistics, global commodity markets, and cutting-edge offshore engineering.
Maritime oil and gas activities influence global energy security, geopolitical stability, and economic development. The safe and efficient movement of petroleum and LNG ensures a stable energy supply for industries and households worldwide.
Strategically located maritime chokepoints – like the Strait of Hormuz, Suez Canal, and Strait of Malacca – are vital arteries of global commerce, but also vulnerable to political tensions, piracy, and environmental incidents.
The sector has been a driver of innovation in deepwater engineering, hull design, navigation systems, and safety management, setting standards later adopted in other maritime fields. At the same time, it is under pressure to reduce emissions, prevent spills, and transition toward more sustainable practices. The balance between meeting today’s energy demands and preparing for a low-carbon future is one of the defining challenges of our time.
• Understand offshore operations – Study platform types, drilling technologies, and safety systems.
• Map the energy supply chain – Trace the journey from offshore wellhead to refinery, identifying key maritime stages.
• Follow global market signals – Learn how oil price shifts, LNG demand, and OPEC+ decisions affect maritime flows.
• Learn the legal landscape – Explore conventions like MARPOL, UNCLOS, and specific energy transport agreements.
• Invest in safety & sustainability skills – Consider BOSIET certification, LNG handling courses, or oil spill response training.
• Think beyond oil – Explore how offshore infrastructure may adapt to offshore wind, hydrogen, or carbon capture projects in the coming decades.
Some modern LNG carriers can carry enough gas in a single voyage to power an entire country for several days.
