A rugged screw-threaded pipe connector for handling corrosive or contaminating fluids under high pressure in a pipeline or pipe riser surrounded by a body of water and subject to high static or dynamic stresses and bending forces. The connector is provided with coarse threads having stabbing flanks and with load flanks adapted to support high loads. The connector is provided with multiple sealing means arranged within the body of the connector that isolate the threads from fluids outside the connector or within the bore of the connector.

A method of providing a cathodic protection to an installed pile is disclosed in which a plurality of anodes are provided on a tendon foundation guide assembly which is attached to a lowering unit and lowered to the pile. The tendon foundation guide assembly is attached to the installed pile and at least one of the anodes is electrically connected to the pile. The tendon foundation guide assembly is then separated from the lowering unit. In another aspect of the invention, a tendon foundation guide assembly is disclosed for deployment upon the top of an installed pile for cathodically protecting the pile and a tendon receptacle inside the pile.
