摘要:
A mooring method of the present invention includes a transportation step of transporting a mooring member (1) having a mooring cable (10) which can be connected to a float at one end (10a) thereof and an accommodation member (20) which is installed at the other end (10b) of the mooring cable (10) and has an accommodation space (20s) therein to a mooring position of the float, a first accommodation step of accommodating a first heavy weight in at least a part of the accommodation space (20s) of the accommodation member (20) at the mooring position, a connection step of connecting the one end (10a) of the mooring cable (10) to the float at the mooring position after the first accommodation step, and a second accommodation step of accommodating a second heavy weight in the accommodation space (20s) of the accommodation member (20) by adding the second heavy weight to the first heavy weight or exchanging at least part of the first heavy weight with the second heavy weight at the mooring position after the connection step.

The present invention relates to a fixed type structure unit for restoring lost sand, a structure and a restoring method. To this end, the present invention is characterized by restoring lost sand using the Venturi effect by providing a fixed type cover structure unit underwater to restore lost sand due to erosion, wherein: both end parts in a length direction are open and are provided with an inlet part and an outlet part respectively; an erosion part is provided to be open in a bottom part; the height of the cross section is arranged to become higher towards the inlet part along the length direction; and a hollow part through which water flows is provided integrally inside the fixed type cover structure unit.

A caisson breakwater module having an upwave and a downwave side and incorporating an oscillating water column, the caisson breakwater comprising a base installed on the sea bed and a lid adapted to be positioned on top of said base, the base defining a water inlet on the upwave side and further defining a water oscillation chamber, and the lid defining a breakwater section on the upwave side, a turbine chamber, one or more air ducts connected with said turbine chamber and an additional substantially sealed chamber. The invention further relates to a breakwater comprising a plurality of such modules and a lid suitable for use in such modules.

Disclosed is a removable erosion-control and fencing (“REAF”) system for shoreline preservation along a line defined by a plurality of posts. An exemplary REAF system comprises first and second post clamp pairs mounted to adjacent posts. Each post clamp pair “sandwiches” a post and is fixedly attached to the post by virtue of fasteners that lock one half of the post clamp pair to its other half. In this way, the post clamp pair “hugs” the post and is secured thereon without having to be permanently fixed to the post or damaging the structural rigidity of the post. Each post clamp pair includes a substantially vertical wall slot such that one or more cross-members may be received into the walls slots to form a wall section in a space defined between the adjacent posts.

To provide an easily constructible steel wall having a wall body in which steel sheet piles capable of easily providing a high water stopping performance are coupled, and reinforced by a steel pipe or an H-shaped steel. The wall body 4 is provided by coupling the plurality of hat-shaped steel sheet piles 1 by a joint. The steel pipe 2, which reinforces the wall body 4, is provided being arranged along a longitudinal direction of the wall body 4. A space is provided between the wall body 4 and the steel pipe 2. The wall body 4 is formed into a corrugated shape in which a projection and a recess are repeated in a longitudinal direction as a steel sheet pile wall. The steel pipe 2 is disposed such that a part thereof is being entered into a recessed portion of the wall body 4. A head portion of the wall body 4 is coupled to a head portion of the steel pipe 2. The wall body 4 and the steel pipe 2 are coupled by concrete. Load transmission is performed between the wall body 4 and the steel pipe 2. Accordingly, the steel wall 3 may have a structure in which an acting earth pressure and water pressure are received and shared by the wall body 4 and the steel pipe 2.

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.
