Claims6
An offshore well test platform system positionable above one or more underwater wells comprising:
- a submergible buoy to be restrained below the surface of the water and above one or more underwater wells;
- a platform structure connectable to the buoy and having an upper portion extending above the surface of the water when connected to the buoy in an installed condition;
- a well test platform deck connected to the upper portion of the platformed structure;
- flexible riser means extendable between the one or more underwater wells and the platform deck for providing passage therethrough for well test or workover operations;
- and
