Platform for controlled containment of hydrocarbons

Platform for controlled containment of oil and condensate, comprising:

• a support structure;
• a deck superstructure positioned on top of the support structure, from where drilling may be performed, the support structure comprising collecting tanks which form an integrated part of the support structure;
• and
• a base structure configured to rest on a seabed, and comprising a number of separate buoyancy bodies placed on top of each other and interlocked, and resting on the base structure by means of the weight of the buoyancy bodies, the buoyancy bodies interlocked to the base structure by means of vertically tensioned cables evenly arranged around a periphery of the platform, and a plurality of mooring cables anchored to the sea bed at a large distance from the platform, the mooring cables being connected to the platform via fairleads and winches,
• wherein the base structure is fixed to the seabed by means of a plurality of piles or conductor tubes, pressed and cemented down into the seabed,
• wherein a fixing point for the vertically tensioned cables coincide with upper ends of the piles or conductor tubes.
