Seaborne oil, also known as crude oil, is a fossil fuel that is primarily composed of hydrocarbons. Hydrocarbons are organic molecules that contain only carbon and hydrogen atoms, and they are the building blocks of many organic compounds, including crude oil.

Crude oil contains a wide range of hydrocarbons, including alkanes, alkenes, and aromatics, which vary in size and complexity. The composition of hydrocarbons in crude oil can vary depending on the source and location of the oil deposit.

Hydrocarbons in seaborne oil can have both beneficial and harmful effects. On the one hand, hydrocarbons are an important source of energy and are used to produce a wide range of products, including gasoline, diesel fuel, and plastics. On the other hand, the release of hydrocarbons into the environment can have negative impacts on marine ecosystems and human health.

When oil is spilled into the ocean, the hydrocarbons can form a slick on the surface of the water, which can harm marine life and birds. Additionally, the hydrocarbons can contaminate beaches and other coastal habitats, impacting tourism and local economies.

To mitigate the risks associated with seaborne oil, regulations and protocols have been developed to minimize the potential for oil spills and to respond quickly and effectively in the event of a spill. These measures include requirements for double-hulled tankers, oil spill response plans, and training for oil spill responders.
