  • Patent number: 10919606
    Abstract: This publication relates to a shallow water terminal, preferably for storing and loading or unloading hydrocarbons, such as LNG, oil or gas. The base structure comprises a floatable, and removable seabed substructure (10) intended to be supported by a seabed (30), the seabed substructure (10) comprising a base structure (11) provided preferably with an upwards extending wall structure (22), arranged along at least a part of the periphery of the base structure (11), the base structure (10) preferably also being provided with an opening (23) in the wall structure (22) for allowing the floatable module to be berthed in and supported by the seabed substructure (10). The base structure (10) is provided with strong points (24) configured to receive the ends of preinstalled vertical piles (14) for at least temporary support of the base structure (11) during a piling operation for permanent piling of the base structure (10) to the sea bed (30).

  • Patent number: 10633815
    Abstract: A shallow water seabed terminal for storing and loading or unloading hydrocarbons, such as LNG, oil or gas, includes a removable floatable module and a removable seabed substructure intended to be supported by a seabed. The floatable module is releasably fixed to the seabed substructure so that a harbour terminal is formed. The seabed substructure includes a base structure provided with buoyancy devices, a wall structure extending upwardly from the base structure and arranged along at least a part of the periphery of the base structure. The base structure is also provided with an opening in the wall structure for allowing the floatable module to be berthed in and supported by the seabed substructure. The base structure is provided with a submerged beam or base slab structure which extends laterally out from the vertical wall structure and is configured to support the floatable module.

  • Patent number: 10590618
    Abstract: Various embodiments relate to a method and a seabed supported base structure for providing a shallow water drilling terminal, where a prefabricated floating seabed substructure is towed to site, ballasted to rest on the seabed and/or piled to the seabed forming a seabed foundation. The seabed supported base structure is provided with at least one cantilevered unit with openings for drilling of wells, projecting sideways out from the exterior side of a vertical wall, terminated above sea level. A prefabricated floating drilling module provided with an outrigger with sidewise movable drilling device is towed to the site, guided into the seabed substructure through an opening in the wall structure at the periphery of the base structure, ballasted and mated onto the base structure, whereupon wells are drilled from a drilling gear. Upon completed drilling and operation of the wells, the drilling unit is removed and substituted by a production unit.
