Abstract: A weak link (17, 43) for a riser system comprising a pin (2, 25) and a box (1, 24), bolts (11, 34) for releasably connecting the pin (2, 25) and the box (1, 24), the bolts being designed to break at a predefined tension. The link further comprising a pressure balancing mechanism for balancing axial forces acting on the bolts (11, 34) due to end cap effect. The weak link also comprises a strong mode mechanism and a dampening mechanism.

Abstract: A cable arrangement for feeding power and signals to downhole equipment, such as an electrically submersible pump (6), within an oil or gas well, comprising an upper suspension element (15), a lower connector (22), a docking station (11′) for the downhole equipment coupled to said connector (22), and a cable (8a), comprising lines for power and signal. The cable extends between, and is coupled to, the upper suspension element (15) and the lower connector (22). The docking station (11′) is adapted for attachment to the inner surface of a production tubing (5), that a narrow gap is formed between the production tubing (5) and the downhole equipment (6). The cable (8) is shaped to fit inside the gap by having a first dimension in the radial direction of the gap, which is smaller than the gap and a second dimension in the tangential direction of the gap, which is substantially larger than the first dimension.
