Zusammenfassung:	A subsea assembly (11) includes a guideframe (19) which receives a control pod (21). The guideframe (19) is in fluid communication with either a blow out preventer (BOP) (13), a lower marine riser package (LMRP) (15), or both. The control pod (21) is in communication with a surface vessel and is used to control the functions of the BOP (13) or the LMRP (15). Electrical and hydraulic connection can be established between the control pod (21) and the subsea assembly (11) without the use of remote operated vehicle. This is achieved by a piston (59, fig 3) which is used to extend a stab assembly (55, fig 3) into engagement with control panels (33, fig 2) that are in commutation with the BOP (13) and the LMRP (15). Springs (81, fig 4A) and slideable plates help align electrical connection to the BOP (13) and LMRP (15) upon engagement of stab assemblies and stab receptor assemblies.
