The licences were awarded in Britain's 26th licensing round which, according to the UK Department of Energy and Climate Change (DECC), resulted in a total of 144 new licences to extract oil and gas from UK waters.
A Maersk Oil spokeswoman confirmed that the Danish company got six licences but declined to give further details.
Maersk got four operatorships and stakes in two other licenses in which France's GDF Suez and Total are the operators, the DECC said on its website.
