Abstract
An arrangement for resolving a hydrate plug (1) in a pipeline (2), such as tubing, drill pipe, casing etc., is described, said arrangement comprising a heating device (4) run on wire line. The heating device (4) is elongated and spear shaped and is mounted on a stroking device (3), the stroking device (3) being adapted to provide a pushing force of sufficient strength to force the heating device into the hydrate plug (1). The heating device then has a large surface towards the hydrate plug. When heat is applied to the heating device, the hydrate plug will melt. A hydrate inhibitor may be added to the liquid near the hydrate plug.
