  • Method for retrieving a geographical point on the seabed
    Patent number: 8269669
    Abstract: The invention involves one or more radio markers (1) being located on or buried in the seabed with a suitable tool at a location where a geographical point requires to be retrieved. Radio markers may be deployed, for example, by means of a subsea vehicle (2). The subsea vehicle (2) is equipped with a positioning system and gyro (6) when the radio markers (1) are deployed, thereby enabling the approximate position of each individual radio marker (1) to be recorded with global map position. A subsea vehicle equipped with a radio antenna detects radio markers after returning to the approximate position by means of the coordinates.

  • Hinged and segmented pipe
    Patent number: 7448414
    Abstract: A rigid pipe (1) is achieved according to the invention in that half-cylinder shaped elements (2) are joined/hinged (3) to each other and where to a such chains are connected together with their concave sides in a zipper-like motion. The two half-cylindrical chains are spooled (13) up individually on each side of a housing (12). This result in a particularly rigid pipe of varying length with a wide area of use.
