Embodiment Construction

[0042] Figure 1 to Figure 8 Four double counterweight arms for transporting fluid products according to the invention are shown and four embodiments of the main balancing system are shown.

[0043] They are, for example, counterbalanced marine arms for transporting fluid products, especially petroleum products such as liquefied natural gas, for loading tankers provided with suitable pipes or conduits from fixed storage to which the arms are permanently attached.

[0044] In these forms of embodiment chosen by way of example only to illustrate the application of the invention, these handling arms generally comprise deformable tubular sections adapted to utilize hydraulic motors or known types of Any other device (coupling) disconnected (only in image 3 ) is connected to a fixed conduit leading to a storage device (not shown) and terminating in a coupling, and is adapted to be connected to a second pipeline (not shown) carried by a tanker (not shown itself).

Abstract

The invention provides a balanced arm (201 ) for transferring a fluid product. The balanced arm (201 ) for transferring the fluid product comprises a transfer compass comprising an inner transfer member (208) and an outer transfer member (221 )articulated together, and a counterweight system(203) for balancing the transfer compass, and is characterized in that the compass is installed on a turntable (215) rotatable about a vertical axis, to rotationally drive the transfer compass about that axis, and the balancing system comprises at least one counterweight (207; 207') mounted on a support (251 ) fixed to the turntable so as to be able to turn about an axis (206) of horizontal general orientation, and functionally be linked to the inner transfer member to provide the balancing of the transfer compass.

Description

technical field [0001] The present invention relates to a balancing arm for the transfer (loading and / or unloading) of fluid products, such as petroleum products (liquefied natural gas, etc.). [0002] More specifically, the present invention relates to a double counterweight marine fluid handling arm, equipped with a hydraulic coupling, thereby permitting the transfer between two ships berthed side by side, between a ship berthed side by side and a platform or floating barge, or between said Transfer between the quay on which the loading arm is mounted and a ship moored alongside the quay. Background technique [0003] Examples of such arms are described in patent documents WO02 / 22491 and GB1395909. One of the main disadvantages of the arms described in these documents is their fixed base, which does not allow easy access to the arms, especially for maintenance operations. [0004] Baseless arms do exist, of the kind described in US4408943, but their accessibility is not ...
