control pods choke kill lines aligned choke kill line connectors 26 interconnect choke kill lines 36 and choke kill valves 30 on stack 14 and abp 16 to choke kill lines 38 on riser connector 20 control pods 24 of lmrp 12 provide control signals to bop stack 14 while auxiliary control pods 34 on bop stack 14 provide control signals to abp 16 in certain embodiments ram bop 39 s 28 in abp 16 are controlled by auxiliary control pods 34 which may be communicatively linked to control pods 24 via umbilical jumpers or some other releasable connection in certain embodiments the control functions for ram bop 39 s 28 of abp 16 as well as control functions for other equipment may be integrated into control pods 24 on lmrp 12 thus eliminating the need for auxiliary control pods 34 because abp 16 is operated with bop stack 14 hydraulic accumulator bottles 42 mounted on the bop stack can be used to support operation of the abp abp 16 may also comprise a remotely operated vehicle rov panel that provides control of the abp functions by an rov lmrp 12 and bop stack 14 are similar to and can operate as a convention two component stack assembly abp 16 is installed between wellhead 18 and bop stack 14 and provides additional ram bop 39 s 28 to provide redundancy and increase.
