Abstract
The present invention relates to an arrangement in a pipe bundle, more specifically to a method and a system for heating subsea or on-shore pipelines, especially pipelines for transportation of substantially oil, gas and water, said pipelines (8, 108, 208) being arranged in a substantially cylindrical outer carrier pipe (1, 101, 201), and for the purpose of providing an arrangement wherein the quantity of heating cable can be reduced, and wherein the manufacturing of such arrangement can be simplified, at the same time as the finished arrangement will provide appropriate heating of the pipelines and the contents thereof, it is according to the invention suggested an arrangement comprising: PA1 a carrier pipe (1, 101) having an outer and/or inner thermal insulation (2, 102), PA1 one or more longitudinally extending energy carriers (3, 4, 5; 103, 104, 105) extending in the longitudinal direction of said carrier pipe (1, 101) for the dissipation/transfer of heat directly and/or indirectly to said pipelines (8, 108), respectively said pipe bundle or bundles, and thereby to the contents of said pipelines.
