The HSBT is a flexible tether with sections of high stiffness. This tether solution will increase the stiffness several times compared to existing WLR tether application and at the same time the flexibility of a wire/rope will be partly maintained.

The HSBT can be used in a WLR tether system where wells offer high bending stiffness in combination with long tether lines to achieve a high WLR efficiency. It can also be used to increase WLR efficiency on normal well stiffness wells when this is required.
