Maritime covers any activity or object relating to the sea, particularly where it is in connection with marine trading or naval matters. This includes ports, ships, vessels, and offshore oil rigs (along with their crew and activities). Maritime activities also extend to those based onshore such as shipbuilding and repair, naval architecture and engineering. Sea going careers in maritime can begin with a training program or apprenticeship where qualifications are gained along with on-the-job training, or by starting at the bottom from an entry level position and working up to a more senior role. Most onshore maritime jobs will require a university level degree or similar.
