Abstract

Subsea heating assembly, comprising a component interface cable (9) in association with a subsea component (7′) to be heated. The component interface cable receives power from an electric power source. The power source comprises an induction coupler (100) with core rings which surround an alternating current carrying source cable (5), and a winding cable (107) wound around the core ring The winding cable connects to the component interface cable. The induction coupler comprises an upper section (100a) with first core parts (101a) and a lower section (100b) with second core parts (101b). The winding cable is arranged in the upper section. The first core parts are aligned with second core parts when the upper section is landed on the lower section. The upper section is removable from the lower section.
