Problems solved by technology

Furthermore, due to the potentially large length of the tube, said interaction can cause the tube to vibrate, which can cause tube fatigue
Under adverse conditions, vibrations may occur at the resonant frequency of the tubes, which can cause catastrophic failure of one or more tubes

Embodiment Construction

[0046] refer to figure 1 with figure 2 , which discloses an overview of a platform mechanism 1 for offshore oil and gas development according to an embodiment of the present invention. The platform mechanism 1 is particularly suitable for water depths of 40-120m. The platform mechanism 1 comprises an elongated structure 3 and an anchoring mechanism 4 .

[0047] The elongated structure 3 comprises a base part 5 and a top part 7 . The base part 5 is anchored in the seabed of the sea such that a part of the base part 5 is embedded in the seabed and another part of the base part 5 is in the sea above the seabed. The structure 3 is anchored in the seabed such that the structure 3 extends from the seabed towards and above the surface of the sea. The structure 3 can be anchored at a well opening 9 or a well opening 9 to be formed in the seabed by drilling operations.

[0048] The platform mechanism 1 also includes a platform 10 and a plurality of tubes 12 . The platform 10 is ...

Abstract

A platform arrangement (1) for offshore energy exploitation comprising an elongated structure (3) with a base portion (5) and a top portion (7). The base portion is adapted to be anchored in the seabed of the sea so that the elongated structure extends away from the seabed towards the surface of the sea. The top portion is adapted to hold process equipment (11) for said exploitation. The arrangement further comprises a plurality of pipes (12) for the operation of the exploitation extending from the base portion to the top portion of the structure. The structure comprises an outer casing (50) and an inner casing (52) arranged so that an outer space (54) is formed between the outer casing and the inner casing. The plurality of pipes are arranged so that they extend in said outer space from the base portion to the top portion of the structure.

Description

technical field [0001] The invention relates to a platform mechanism for offshore energy development, especially oil and gas development. The platform mechanism can also be used for other offshore energy development, such as wind energy, solar energy, etc. The mechanism includes an elongated structure including a base portion and a top portion. The base portion is anchorable into the seabed of the sea such that the elongated structure extends away from the seabed towards the surface of the sea. The top portion can hold processing equipment for the development. The mechanism also includes a plurality of tubes for the operation of the development and extending from the base portion of the structure to the top portion. Background technique [0002] Prior art offshore oil platforms generally comprise a structure of a minimum of 3 legs firmly anchored in the seabed. These platforms provide a stable structure for withstanding severe marine conditions of wind, currents, waves, ...
