module for an underwater structure, external element configured to engage with a module, structure comprising a plurality of modules, method for fabricating a module, and underwater structure.

摘要

A module for an underwater structure is described. the module comprises a plurality of walls defining a cavity configured such that at least two walls of said plurality of walls face each other to provide respective stack support surfaces for supporting said module, said walls are substantially parallel. to form complementary stack surfaces such that one stack surface can be supported on one surface and the other supplementary stack surface provides a bearing surface for another module. two or more walls of said plurality of walls each comprise an opening providing a conduit through each two or more walls to said cavity, respective openings of said two or more walls and said cavity configured to provide a flow path of water into, through and from said cavity. The water flow path may be considered unrestricted or at least substantially unrestricted in that water may flow through the openings and cavity without deviation or interruption except through the walls of the module or cavity. in the stacked formation, an opening may be closed or partially closed, but still the module, when by itself, may provide waterways that may be considered unrestricted or substantially unrestricted.
