Unmanned or remotely operated platform
An unmanned wellhead platform ( 1 ) (UWP) comprising a jacket ( 10 ) designed and adapted to be supported on the seabed and projecting above the sea level is shown. The unmanned wellhead platform ( 1 ) includes a topside installed on top of the jacket ( 10 ). The topside is designed as a standardized base concept tailored for repetitive future topside constructions ( 3 ). Each topside construction ( 3 ) is adapted to the number of wells to be developed. The topside construction ( 3 ) is made up by a number of different but standardized sections ( 4 ). Each standardized section ( 4 ) is dedicated for a particular and predetermined purpose and location in the topside construction ( 3 ).
1. An unmanned wellhead platform comprising:
a jacket configured to be supported on the seabed and projecting above the sea level;
a topside structure installed on top of the jacket and comprising at least two decks;
wherein the topside structure is expandable via the addition of one or more standardized sections, the topside structure being adapted to a number of wells to be developed, the topside structure comprising a plurality of different standardized sections, each of the plurality of different standardized sections being dedicated for a particular and predetermined purpose and location; and
wherein the plurality of different standardized sections adopt different sizes and configurations and are grouped in sets of sections having equal dimensions.
2. The unmanned wellhead platform according to claim 1 , wherein some of the plurality of different standardized sections have at least one defined well slot, each well slot having received its respective and unique number from 1 (one) and up, wherein each numbered well slot repeatedly receives the same location in the topside construction each time a base topside construction is constructed.
3. The unmanned wellhead platform according to claim 1 , wherein at least one of said plurality of different standardized sections is adapted to receive and mount various components associated with a dedicated well.
4. The unmanned wellhead platform according to claim 1 , wherein the plurality of different standardized sections are grouped in standardized structural sections and standardized equipment sections.
5. The unmanned wellhead platform according to claim 1 , wherein each of the plurality of different standardized sections spans over at least two decks.
6. The unmanned wellhead platform according to claim 5 , wherein each of the plurality of different standardized sections spans over three decks, the three decks being a cellar deck, a middle deck and a weather deck.
7. The unmanned wellhead platform according to claim 1 , wherein the topside structure comprises a plurality of dedicated well slots selected from eight, twelve, and sixteen dedicated well slots, each well slot being adapted to receive required components for one respective well.
8. The unmanned wellhead platform according to claim 1 , wherein the topside construction is rotated in the horizontal plane approximately 45 degrees relative to corner legs of the jacket.
9. The unmanned wellhead platform according to claim 1 , wherein the jacket is an equilateral jacket adjusted for sea depth, metocean data, soil condition, and strength required for the location of the unmanned platform.
