Abstract
A method for connecting sections of a multi-bore structure in water comprises connecting the sections to bring corresponding bores of the sections into mutual alignment while those bores are each closed by a plug that excludes the water from the bores. Then, with the sections connected and the corresponding bores sealed together in fluid communication with each other, the plugs are flushed away in a flushing fluid that flows along the communicating bores.
