A system and method for mooring of and supply electrical power to a vessel

A system for mooring of and supply electrical power to a vessel, the system comprising:

• a mooring buoy being configured to float on a sea surface and to be anchored to a seabed;
• a mooring connection being a combined mooring and electrical connection by comprising a mooring line and an electric conductive cable for supply of said electrical power, wherein said mooring line is configured to take-up tension arising from a vessel being moored to said mooring buoy by use of the mooring connection while essentially no mooring tension is applied to the electrical conductive cable, said mooring line is connected to said mooring buoy or anchored to the seabed at the seabed;
• a retractable vessel connector provided at an end of the mooring connection, said vessel connector being a combined mooring connector and electrical connector, and
• a gripping device arranged on a vessel, said gripping device being configured to grip and lock said vessel connector to moor said vessel to said mooring buoy or to the seabed.
