The present invention discloses a brick, comprising a brick body, which comprises at least one slot position for connecting a column, and a method for using the bricks to build dikes in water, including the following steps: (1) drilling a plurality of pile holes at water bottom; (2) casting concrete into each of the pile holes to form concrete columns; (3) stacking up a number of the bricks along the concrete columns and having them tightly connected to form a wall; (4) filling the clearances between the concrete columns and the bricks with mortar. The bricks and dike building method provided by the present invention are suitable for direct over-water dike building, the construction is fast and the dikes built are firm and stable, have superior waterproof function and can effectively prevent the impact of currents, winds and waves.

A metal fin tube foundation includes a pair of coupled metal plates, each plate being comprised of a plurality of flat panels, wherein each panel is positioned at an angle relative to an adjacent panel, and each plate including a fin on each lateral end of each plate, wherein each fin overlaps a fin of the other metal plate forming two pairs of overlapped fins, wherein the plates are coupled along each of the two pairs of overlapped fins; wherein the plurality of panels of the coupled two metal plates form a closed perimeter polygon shape having an open interior and wherein each pair of overlapped fins form a combined fin element which extends away from the perimeter of the polygon.

The invention relates to an offshore drilling or production vessel comprising a platform and a mooring system attached thereto, said mooring system comprising: i.) a support frame with a winch-drum mounted thereon; ii.) a mooring line for mooring said platform to the ocean floor, said mooring line comprising a first portion and a second portion; wherein said first portion is hauled on and paid off by said winch-drum; wherein said second portion is anchored to the ocean floor; characterized in that the mooring line is a single length mooring line comprising high strength polyolefin fibers; wherein the first portion of the mooring line has a first mass (M1) of polyolefin fibers per unit length and the second portion of the mooring line has a second mass (M2) of polyolefin fibers per unit length; wherein the ratio M1/M2 is greater than 1 and wherein said first portion extends continuously into said second portion through a tapered portion of the mooring line.

A tree house propped upon a simulated tree trunk has a platform, a cabin thereon, a main support column supported in a ground anchor, a plurality of diagonal struts, and a variety of simulate tree dressings for the column and struts. The cabin is built upon the platform and forms an inner living space that is served with potable water utilities, waste water utilities, and public-utility electric service. The main support column extends downward from the platform about a relative center of mass of the platform and cabin together, to ultimately sink into the ground anchor. The plurality of diagonal struts extended diagonally downward from the cabin radially spaced away from where the column extends downward from the platform, and join the column intermediate the platform and ground anchor. There furthermore are simulated tree trunk dressing covering the column, and, simulated tree branch dressing covering the struts.
