The UK installed 854MW of wind generation capacity in 2012, bringing the total British offshore wind capacity to 2.9GW, according to the European Wind Energy Association (EWEA).
During the 12 months, nine wind farms were fully connected to the National Grid, representing investments of around €3.4bn to €4.6bn.
The report also showed Europe installed 1,165MW in offshore wind capacity last year, with 293 turbines installed and connected to the grid, bringing the total of turbines to 1,662.
Of this total capacity, 73% was installed in UK waters in 2012.
Overall, the UK remains the leader with 58.9% of Europe's total offshore capacity, followed by Denmark (18%), Belgium (8%) and Germany (6%).
RenewableUK Offshore Renewables director Nick Medic said: "The offshore wind industry is continuing to attract investment and creating jobs. We anticipate that more than 47,000 people will be working in the offshore sector by 2021."
Meanwhile, Scottish Renewables has announced that offshore wind developers have so far injected £165m in the Scottish economy.
The investment figure represents all contracts awarded by developers with Scottish companies in advance of any permissions being awarded to their projects.
Scottish Renewables' offshore renewables senior policy manager Lindsay Leask said: "This level of investment, made in advance of their projects gaining consents, shows the considerable level of confidence developers have in Scotland's offshore wind sector."
