Blowout preventer system and method

A blowout preventer (BOP) for controlling pressure within a wellbore, comprising:

• an internal cavity;
• a front side including a door opening, the door opening providing access to the internal cavity;
• a door associated with the door opening, the door being movable between a first position and a second position, the door blocking access to the internal cavity in the first position and enabling access to the internal cavity in the second position;
• and
• a hinge coupled to the door, the hinge comprising:
• a hinge body, the hinge body secured to a body of the BOP;
• a hinge coupling coupled to the door;
• and
• a rotation mechanism arranged at an interface between the hinge body and the hinge coupling, the rotation mechanism securing the door in the second position or in a third position, the third position enabling access to the internal cavity,
• wherein the rotation mechanism further comprises:
• a body region having a first end and a second end;
• a first opening at the first end;
• and
• a second opening at the second end;
• wherein the first and second openings are configured to receive a pin, the pin engaging the second opening and a receptacle in the hinge coupling, the door being secured in the second position when the pin engages the first opening and in the third position when the pin engages the second opening.

A door assembly for providing access to an internal cavity of a blowout preventer (BOP), comprising:

• a door associated with a door opening, the door being movable between a first position and a second position, the door blocking access to the internal cavity in the first position and enabling access to the internal cavity in the second position;
• and
• a hinge coupled to the door, the hinge comprising:
• a hinge body;
• a hinge coupling coupled to the door;
• and
• a rotation mechanism arranged at an interface between the hinge body and the hinge coupling, the rotational mechanism securing the door in the second position or in a third position, the third position enabling access to the internal cavity,
• wherein the rotation mechanism further comprises:
• a body region having a first end and a second end;
• a first opening at the first end;
• and
• a second opening at the second end;
• wherein the first and second openings are configured to receive a pin, the pin engaging the second opening and a receptacle in the hinge coupling, the door being secured in the second position when the pin engages the first opening and in the third position when the pin engages the second opening.
