A floating arrangement may include at least one support-floatation-unit for supporting a solar panel, the at least one support-floatation-unit has a main body having a flat base and at least one connection portion; and at least one connecting-floatation-unit having a flat base and at least one connection portion. The respective corner-connection-portions may be coupled together to form a connection joint connecting the support-floatation-unit and the connecting-floatation-unit in a side-by-side arrangement. A height from the base of the support-floatation-unit to the connection joint may be larger than a height from the base of the connecting-floatation-unit to the connection joint such that the base of the support-floatation-unit may extend downwards from the base of the connecting-floatation-unit by a depth which defines an additional displacement volume of the support-floatation-unit configured to provide additional buoyancy to support the solar panel.

A house is provided. The house includes a base and a roof. The roof is attached to the base. The base has sufficient buoyancy to enable the house to float on water.

In a membrane type heat insulation system for a cryogenic liquefied gas carrier cargo tank and a liquefied gas fuel container, a secondary heat insulation layer comprises a plurality of panels which are stacked in multiple layers while each pair of upper and lower panels is arranged to intersect each other, whereby heat loss which may occur in the gap between the panels can be minimized and deformation due to a temperature difference can be minimized.

An improved hull penetration assembly, and various components thereof are provided. These include a hull penetration mount with braces thereon, as well as a hull penetration mount comprising a lower chamber and a removable hatch coupled thereto. These further include a kit comprising these and other improvements together with a plug insertion apparatus, an object delivery apparatus, a light delivery apparatus and a borescope apparatus.

The present invention relates to an apparatus for passively preventing a marine floating body from twisting during mooring by controlling tension in ropes connected to the marine floating body within a predetermined allowable limit. The apparatus includes: a floating main body connected to the ropes, fixed on the sea, and providing a space for marine work; winches disposed on the floating main body and retracting or releasing the ropes fixing the floating main body; fairleads disposed on portions of the floating main body and guiding the ropes to the winches through themselves; and braking units disposed on portions of the floating main body at a predetermined distance from the fairleads, with the ropes passing through the fairleads and themselves, and controlling a speed of the ropes that are retracted to the winches at a predetermined speed.

A floating structure having at least one row of floating rectangular parallelepipedal modular blocks, one block having four vertical peripheral faces that meet at four vertical edges, each vertical edge bearing an assembly lug in which an assembly system can be received in order to join the block to one or more adjacent blocks, each row having a plurality of blocks joined to one another by assembly systems arranged in two diagonally opposite lugs of each block, with the exception of two end blocks, the floating structure being configured so that each block is joined to an adjacent block by a single assembly lug.

In order to provide a rudder blade, which has a low level of weight, is easier and more inexpensive to manufacture, that meets the various strength and stability requirements for various rudder-blade sections, which can be at least partly manufactured in an automated manner and for which the manufacturing of irregular surfaces, in particular, the leading edge, is made easier, a rudder blade is proposed, which has a modular structure, wherein the rudder blade comprises at least two prefabricated rudder-blade segments and is composed of the at least two prefabricated rudder-blade segments.

A platform assembly configured to be coupled to a tower of a sea vessel. The platform assembly includes a platform, a series of brackets configured to be coupled to the platform, and a series of clamps configured to be coupled to the series of brackets. The series of clamps are configured to detachably couple the platform assembly to the tower of the sea vessel.
