Abstract: A seal assembly can include a sealing component and a spring energizer located within a seal cavity or spring cavity of the sealing component. The sealing component provides an exterior surface for providing protection of the seal cavity and spring energizer from an external or contaminated environment, such as the atmosphere. The sealing component can have two distinct first and second sealing points. Each distinct first sealing point can have two discrete first sealing points and each second sealing point can have two discrete second sealing points. Part of the spring energizer can extend externally of the sealing component.

Abstract: An assembly includes a first waveguide and a second waveguide extending longitudinally along a first axis, each having an end, each comprising a first annular groove, the two ends being contiguous along the first axis, and an assembly device for assembling the first waveguide and the second waveguide, wherein the assembly device comprises a sleeve surrounding the ends of the first and second waveguides and having an inner wall comprising two first annular grooves facing the first annular grooves of the first and second waveguides, two reversibly deformable waveguides, each being positioned in a first annular groove of the sleeve and positioned in a first annular groove of the first and second waveguides, so as to block the first and second waveguides in terms of translation along the first axis.

Abstract: An apparatus and method for accessing a sub sea pipeline. The apparatus comprises a entry guide (2) having a channel extending there-through for guiding a pipeline intervention device and means for attaching the entry guide to the external wall of a section of pipeline so that the longitudinal axis (b) through the centre of the channel of the entry guide forms an angle of between about 1° and 10° with the longitudinal axis (a) through the centre of the pipeline section.
