Diverter system is a key component of offshore drilling mostly, and it always services the surface layer driling before BOP. The diverter assembly is the uppermost component of the riser system.It is not used to shut or seal the well completely, but to either direct the returning drill fluid or control the blowout and surface layer gas.When encountering the gas, the diverter can close off around drill pipe or casing, and open the special diection vent line on board at the same time.With the platform manifold, the gas will be guided and choked at special point.
Diverter system must be equipped with hydraulic control system to use. With the different size of packers, it is able to seal various shapes and sizes of drilling tools including kelly, drill pipes, tool joints, drill collar,etc.
