What does offshore mean?
Offshore describes something located, moving, or operating away from the shore. It most commonly refers to activities at sea, such as fishing, drilling, shipping, or the construction of wind farms and platforms. The word can also describe a business or investment situated outside a country’s main financial or legal system, as in offshore banking. Offshore therefore combines a literal geographical meaning with a broader sense of separation from a main land, territory, or established system. It is widely used in British and American English and is especially common in reports about energy, maritime activity, finance, and international business. The related terms onshore and inland provide useful contrasts: onshore refers to movement or activity toward or on land, while inland points away from the coast but not necessarily out at sea.
Situated, operating, or developing away from the shore, especially at sea.
"The offshore platform supplies natural gas to the mainland."
Also used figuratively for business, finance, or other activities conducted outside a particular country or jurisdiction.
Away from the shore or toward the open sea.
"The vessel drifted offshore during the night."
Can also indicate movement or operation away from a country’s mainland or established system.
Offshore is more than a direction: it suggests the open sea and, by extension, a remote or detached position.

Where does offshore come from?
Offshore is formed in English by combining off with shore, following the pattern of words such as ashore and onshore. The compound meaning “away from the shore” developed from the older sense of off, meaning away from or at a distance. Its modern geographical and commercial senses developed as maritime travel, offshore industries, and international finance became more widespread.
How offshore is actually used
