COATING THE FORTIES FIELD SUBMARINE PIPELINE

British Petroleum Co. Ltd. specified a newly developed negative buoyancy coating with high impact-resisting properties for use on the 110 mile, 32 in. dia pipeline from the Forties field to the Cruden Bay shore terminal. One of the ingredients of the coating mix is Aberdeen Granite, possibly the hardest concrete aggregate available. To insure that the coating will stand up to the service conditions expected, the coating was subjected to severe tests simulating the effects of trawl boards, by striking the specimens of coated pipe 60 blows at an angle of 90 deg with a one-ton steel hammer, and 20 blows at an angle of 60 deg, both at a speed of 4 knots. British Petroleum also carried out shear and bending tests on the concrete, and did an experimental laying operation in the Mediterranean, using pipe coated with the new material.
