Abstract

A subsea housing assembly has a subsea housing with first and second housing portions having first and second electrical connections for data communication with a separating wall. An inductive coupler has first and second coupling sections disposed in the first and second housing portions and provides inductive coupling across the wall for data communication between the first and second electrical connections. The inductive coupler has inner and outer coils. The outer coil at least partly surrounds the inner coil and at least part of the wall extends between the inner and outer coil. Soft magnetic material is arranged around the outer coil and/or inside the inner coil where magnetic flux is collected and guided from the outer to the inner coil and/or from the inner to the outer coil. A support structure is provided around and/or inside the part of the wall extending between the inner and outer coil.
