A method of providing a buoyant concrete support structure 10 for an offshore installation, such as a wind turbine. A monolithic multicellular concrete member 11 is formed with at least five cells 14 arranged circumferentially around a central vertical longitudinal axis 20. The diameter of each cell is smaller than a diameter of a circumference along which the cells are arranged. The cells are formed as vertically-extending hollow elements with an enclosed bottom portion provided below a hollow central void 15 thereabove. The cells are formed contemporaneously such that all of the cells are integrally-formed with each other in unison to provide the seamless monolithic multicellular concrete member. The cells are coherent such that each cell shares a common wall portion 40 with an adjacent cell. A support structure formed using the method is also disclosed.
