A system is disclosed for setting inflatable packers underwater. The packers are used to seal the annulus between an anchor pile driven into the sea bed through a leg of the platform or through a skirt sleeve attached to a leg adjacent the sea bed to allow grout to be pumped into the annulus to connect the pile to the leg or skirt sleeve. The packer is inflated by fluid displaced from a pressure chamber located adjacent the packer by fluid under pressure located adjacent the packer, such as the ambient water.
