Sea bed terminal for offshore activities

A shallow water seabed terminal for storing and loading or unloading hydrocarbons, said seabed terminal comprising a removable floatable module, and a removable seabed substructure configured to be supported by a seabed, the floatable module being releasably fixed to the seabed substructure so that a harbour terminal is formed, the seabed substructure including a base structure provided with buoyancy devices, a wall structure extending upwardly from the base structure and arranged along at least a part of a periphery of the base structure, the base structure being provided with an opening in the wall structure for allowing the floatable module to be berthed in and supported by the seabed substructure, wherein the base structure is provided with a submerged beam structure extending along the circumference of the base structure and extending laterally out from the wall structure and configured to support the floatable module, the submerged beam structure being provided with sleeves or ducts extending through the submerged beam structure and being configured to receive piles to be driven down into a soil of the seabed,

• wherein an upper end of each pile is terminated and rigidly locked or anchored in the submerged beam structure ensuring that the weight of the floatable module when berthed is transferred directly through the submerged beam structure and through the piles into a deeper layer of the seabed soil.
