An offshore assembly to operate a facility, in particular an underwater oil and gas production facility. The offshore assembly has: a semi-submersible support structure arranged in a body of water and having at least one tubular portion; a wind turbine to generate electricity and equipped with a tower, a nacelle and a blade assembly. The offshore assembly also has at least one back-up power source mounted on the semi-submersible support structure to generate electricity. A plurality of compartments are stacked on top of each other within the tubular portion. Each of the compartments is dedicated to housing respective equipment to perform respective functions, and a cooling and ventilation system cools and ventilates the plurality of compartments.

Offshore assembly and oil and gas production system and method comprising such offshore assembly

A method of connecting together two unit elements (') of a fluid transport pipe, each unit pipe element being covered in an outer insulating coating (&#x2032;) made of a thermoplastic material, with the exception of an end portion that does not have an outer insulating coating. The method includes: a step of welding together two abutting unit pipe elements; a step of positioning an annular sleeve () around a cut-back and in part around the outer insulating coatings of the two unit pipe elements, the sleeve being made of a thermoplastic material; a step of fastening the sleeve in sealed manner by weld bonding on the outer insulating coatings; and a step of applying an external pressure on the sleeve to enable it to be deformed elastically and match the shape of the respective end portions of the two unit pipe elements.

Method for connecting two unitary elements of a conduit for transporting fluids by means of a sleeve

An installation of bottom-to-surface connections of at least two undersea pipes (--) resting on the sea bottom (), and a rigid pipe (--) constituted by a vertical riser having its bottom end () fastened to a base (--) at the sea bottom (), and having its top end () tensioned by an immersed float (--); and a flexible connection pipe (--) providing the connection between a common floating support () and the top end () of the vertical riser via a junction device (--; wherein two hybrid towers are connected together by at least one rigid separator bar () having a length not less than the diameter of the larger-diameter float.

Facility comprising at least two bottom-surface links comprising vertical risers connected by bars

An installation of bottom-to-surface connections having a plurality of bottom-to-surface connections arranged in a fan from a common floating support. The installation having a first number k of first bottom-to-surface connections, with each first number of connections having a first riser connected to a first undersea pipe tensioned in substantially vertical manner by a first float, and a diving first flexible connection pipe connecting the floating support and first riser. The installation further having a second number m of second bottom-to-surface connection, with each second number of connections having a second rigid pipe connected to a second undersea pipe and tensioned by a second buoyancy element, and a second flexible connection pipe providing the connection between the floating support and the second rigid pipe.
