Problems solved by technology

Including the latter approach in the described scenario is not entirely satisfactory
In fact, the presence of permanent guides on the base makes the equipment unnecessarily heavier and takes up a lot of space on the hull, limiting the number and / or size of equipment pieces that can be placed on the hull deck

Embodiment Construction

[0055] figure 1 with figure 2 A first device 10 intended to be placed in a body of water 12 is schematically shown.

[0056] The apparatus 10 is particularly useful in the production of fluids, in particular hydrocarbons such as oil and / or natural gas, collected at the bottom of a body of water 12 and raised to the surface of the body of water 12 .

[0057] The facility 10 is, for example, a floating production storage and offloading (FPSO) unit or a floating liquefied natural gas (FLNG) unit, a semi-submersible platform (which may be, for example, a tension leg platform (TLP)), an offloading buoy, a floating vertical column, or a vessel . In a variant, the device 10 is a fixed rigid structure of the "gravity-fed" type, such as a "gravity-based structure" (GBS).

[0058] The body of water 12 is, for example, a lake, sea or ocean. The depth of the body of water 12 at the device 10 is for example between 50m and 3000m, or even 4000m.

[0059] refer to figure 1, the device...

Abstract

The invention relates to a method which includes the following steps: providing the base (14), including an upper surface (22) and mountings (16) projecting above the upper surface (22); assembling guiding rails (36) on the mountings (16); placing the module (18) intended for being installed on the base (14) on an upper surface located next to the base (14); translating the module (18) along the guiding rails (36) in order to bring it onto the base (14); placing the module (18) on the mountings (16) so that the mountings (16) support the weight of the module (18); releasing the guiding rails (36) relative to the mountings (16); and removing the guiding rails (36) by horizontal movement opposite the upper surface (22) of the base (14).

Description

technical field [0001] The invention relates to a method for assembling a device intended to be placed in a body of water, the device comprising a base and at least one module placed on the base. Background technique [0002] The equipment is for example a floating production storage and offloading (FPSO) unit, a floating liquefied natural gas (FLNG) unit or more generally an offshore unit such as a semi-submersible platform (which may be, for example, a tension leg platform (TLP)), an offloading buoy , floating vertical columns or ships. In a variant, the device is a fixed rigid structure of the "gravity-fed" type, such as a "gravity-based structure" (GBS). [0003] Floating units of the above-mentioned type generally comprise a floating hull carrying a multitude of equipment elements interconnected. The means of these installations are connected to each other, for example, by pipes, functional lines such as electrical lines, hydraulic transmission lines and / or informatio...
