The invention relates to a device () which comprises a stationary member (), comprising a stabilization means () relative to the bottom of the expanse of water, a member () movable relative to the stationary member (), comprising at least one floating element () intended for remaining on the surface () of the expanse of water, such that the swell drives the movement of said movable member (), a guiding means () substantially vertical to the movement of the movable member () relative to the stationary member (), and a generation means () for electric power, arranged between the stationary member () and the movable member (), intended for converting into electric power the mechanical energy from the vertical motion of the movable member () relative to the stationary member ().

The invention relates to a structure for the transport, installation and dismantling of an oil rig deck, of the type comprising a floating hull provided with legs which can move vertically in relation to the buoyant hull and a shuttle associated with each of said legs and intended to be applied against the lower face of the deck, whereby said shuttle can be moved by the corresponding leg between a low position on the buoyant hull and a high rig deck lifting position.

An observation or aiming system for a self-propelled vehicle is described. The system includes a post pivoting about a bearing axis (Ag) relative to the vehicle. The post carries a body for an optical block and a thermal camera which are mounted to pivot about an elevation axis (As) perpendicular to the bearing axis (Ag). The body and the thermal camera are disposed symmetrically relative to the bearing axis (Ag). The system also includes a radar channel having a radar transmitter unit mounted on the body, a radar detection unit mounted on the body close to the bearing axis (Ag) and concentration means situated in the body for concentrating radar waves on the radar detection unit. The optical block, the thermal camera, and the radar channel are secured so as to always have the same orientation in elevation and in bearing, and thus the same observation direction.

A method of intervention on the seabed (F) using a free end of one riser ( ) originating from a semi-submersible platform ( ) designed for producing oil from a deposit, at a number of distinct intervention points ( ), includes the following successive steps: tethering the platform ( ) to immobilize it in a position floating over the deposit; installing the riser ( ) connecting the floating platform ( ) to the seabed (F) for intervention at a first intervention point ( ); carrying out an intervention at the first intervention point ( ); disengaging the free end of the riser ( ) from the first intervention point ( ), while keeping this end submerged; moving the free end of the riser ( ) with respect to the seabed (F) towards a second intervention point ( ), while keeping the floating platform ( ) in place; and carrying out an intervention at the second intervention point ( ).

Method of setting up a production installation

A support device on the sea-bed for legs of a self-elevating oil-rig platform are characterized in that it comprises an individual and independent shoe (3) intended to be fixed on the lower end of the leg (2) and fitted with a detachable and adjustable locking means (20), for fitting rigidly on the said lower end of the leg (2) .
