摘要:
This publication discloses a harbour plant (10) for storage, loading and unloading of hydrocarbon products at sea, comprising a number of units (9) being mutually placed on the seabed so that a harbour plant is formed. The units (9) are placed independently at a given distance apart in sideways direction and having a front surface along which a vessel is intended to be moored, forming passage(s) for parts of the waves, and being configured to dampen a part of the incoming waves while allowing other parts of the waves and current to pass through the harbour plant. The sideways distances between two neighbouring units (9) is governed by the frequency of the waves to be dampened and the frequencies of the waves allowed to pass in between the units (9). The front surface of one of the units (9) is offset with a distance relative to the front surfaces of two neighbouring in a traverse direction away from said incoming waves, and/or that the units are configured in such way that the width of the passage between two neighbouring units increases or decreases in direction of the wave motion.
摘要:
The publication relates to a shallow water seabed terminal (40) for storing and loading or unloading hydrocarbons, such as LNG, oil or gas, comprising a floatable, removable module (20), and a removable seabed substructure (10) intended to be supported by a seabed (19), the floatable module (20) being releasably fixed to the seabed substructure (10) so that a harbour terminal is formed, the seabed substructure (10) comprises a base structure (11) provided with buoyancy devices, an upwards extending wall structure (12) extending up from the base structure (11) and arranged along at least a part of the periphery of the base structure (11), the base structure also being provided with an opening (18) in the wall structure (12) for allowing the floatable module (20), to be berthed in and supported by the seabed substructure (10). The base structure (11) is provided with a submerged beam or base slab structure (35) extending laterally out from the vertical wall structure (12), configured to support the floatable, removable module, the beam or slab structure (35) being provided with sleeves or ducts extending through the submerged beam or slab structure (35) configured to receive the piles to be driven down into the seabed soil.
