A method and a device for replacing a seal element in an undersea blowout preventer is provided. A complete system includes a control center on the surface, an umbilical from the control center to a remotely operated vehicle (ROV), and a seal element carrier manipulated by the ROV. The carrier includes either retrieving tool or a running tool, which retains a cartridge which is to be inserted into or has been retrieved from a BOP. The cartridge is split along a vertical plane, with each half of the cartridge becoming a temporarily integral part of a pipe ram on either side of the BOP. Alignment ramps on the cartridge mate with complementary surfaces on the respective faces of the pipe rams.
