  • Patent number: 6938695
    Abstract: A subsea well assembly has a guideframe that receives a control pod. The guideframe is in fluid communication with either a blow-out preventer (BOP), a lower marine riser package (LMRP), or both. The control pod is in communication with a vessel, and is used to control the functions of the BOP, the LMRP, or both. Electrical and hydraulic communications are established between the control pod with little or no assistance from a remote operated vehicle. A piston is used to extend a stab assembly into engagement with control panels that are in communication with the BOP and LMRP. The stab assembly can be locked in its upper position while being lowered and landed in the guideframe, and in its lower position after registering with the control panels. Springs and slideable plates help align electrical connections to the BOP and LMRP upon engagement of stab assemblies and stab receptor assemblies.
