Abstract
flexible pipe body and a method of providing electrical continuity are disclosed. The flexible pipe body comprises a first armour layer formed from a helical winding of a metal tape element, a further armour layer formed from a helical winding of a further metal tape element, and at least one intermediate layer between the first and further armour layers, said intermediate layer comprising a helically wound electrically insulating tape element (8000, 8001, 8002, 8003, 8004) and a helically wound electrically conductive tape element (8100, 8101, 8102, 8103, 8104).

Flexible pipe body for transporting production fluids, comprising:
- a first armour layer formed from a helical winding of a metal wire element;
- a further armour layer formed from a helical winding of a further metal wire element;
- and
- at least one intermediate layer between the first and further armour layers, said intermediate layer comprising a helically wound electrically insulating tape element and a helically wound electrically conductive tape element.
A method of providing electrical continuity between adjacent layers of a flexible pipe, comprising the steps of:
- winding an intermediate layer over a first layer;
- and
- providing a further layer over the intermediate layer;
- whereby
- said step of winding the intermediate layer comprises helically winding at least one electrically insulating tape element simultaneously with an electrically conductive tape element over the first armour layer.
