Abstract: A mining system includes: a vessel for processing mined ore, an upper platform coupled with the vessel, a lower platform supported by the ocean floor, a number of transport cables which extend between the upper and lower platform, and a container for containing ore which container is fixedly coupled to a container transporting cable such that the container moves vertically with the container transporting cable to transport the container in a container trajectory extending between the upper and lower platform.

Abstract: The invention relates to a coupling (8) for the releasable coupling of pipe parts, the coupling (8) comprising: a first pipe part (9), which on the inner circumference has two or more rows (18, 19) of lugs (13, 15); a second pipe part (10), which on the outer circumference has two or more rows (30, 31) of lugs (23, 24); wherein the lugs (13, 15, 23, 24) of each of the rows (18, 19, 30, 31) of the first pipe part (9) and of the second pipe part (10) have interspaces (12, 14, 25, 26) which are designed to allow lugs of one pipe part to pass the lugs of the other pipe part for sliding of the pipe parts (9, 10) into and out of one another in the axial direction, and wherein the pipe parts (9, 10), in the slid-together state, can be twisted in the tangential direction to make the lugs (13, 15) of the first pipe part (9) engage on the lugs (23, 24) of the second pipe part (10) for fixing of the pipe parts (9, 10) in the axial direction.
