Embodiment Construction

[0086] It should be noted that in the following detailed description of the embodiments shown in the drawings, the same reference numerals are used for the same or similar structures and features.

[0087] figure 1 A top view of an embodiment of a harbor station 10 according to the invention is schematically shown. The shown harbor site comprises three identical units 11, 11' configured to remain stably on the seabed 12 due to gravity. Three units 11, 11' are placed on the seabed 12 at a distance Q apart, the middle unit 11' is also positioned in a retracted position relative to the two other units 11, with a retracted distance R, the middle unit 11 ' are retracted in the same direction as the general principal direction 13 of the wave. as further shown in figure 1 , the vessel 14 is moored along the intermediate unit 11' on the leeward side of the units 11, 11'. The mooring system used to moor the vessel 14 to the units 11, 11' comprises one or more forward mooring l...

Abstract

The present disclosure discloses a harbor facility (10) for storing, loading and unloading oil and gas products at sea, comprising a plurality of units (11, 11') arranged alternately on the seabed to form the harbor facility. The units (11, 11') are independently positioned at a given distance from the lateral direction and have front surfaces along which the vessel can be moored, thereby forming part of the wave channel, and configured to attenuate incoming waves while Allow waves and currents from other parts to pass through the harbor facility. The lateral distance between two adjacent units (11, 11') is controlled by the frequency of the waves to be damped and the waves allowed to pass between the units (11, 11'). In a transverse direction away from the incoming wave, the front surface of one of the units (11, 11') is offset by a distance relative to two adjacent front surfaces and / or the unit is configured to Increase or decrease the channel width between two adjacent units in the direction of motion.

Description

field of invention [0001] The present invention relates to the transport of oil and gas at sea, and more particularly to a device as stated in the preambles of the independent claims. [0002] In more detail, the present invention relates to the installation and operation of seaport facilities for the storage and loading or unloading of oil and gas, such as liquefied natural gas, at a distance from the shore in shallow waters, where an optional facility for liquefied natural gas is built on shore storage unit or as a flotation unit for mooring. [0003] More specifically, the present invention relates to a marine facility for storing, loading and unloading oil and gas products at sea, said marine facility comprising a plurality of units arranged alternately on the seabed to form a marine facility. The units are intended to be positioned independently, each unit being in spaced relation at a given distance D in the lateral direction and having a front surface along and against...
