Sulphur, the Blowout Protection in Spookys link is called a BOP, In this video they call it a SBOP or Surface BOP.

An accumulator is: A device used in a hydraulic system to store energy or, in some applications, dampen pressure fluctuations. Energy is stored by compressing a precharged gas bladder with hydraulic fluid from the operating or charging system. Depending on the fluid volume and precharge pressure of the accumulator, a limited amount of hydraulic energy is then available independent of any other power source. Well pressure-control systems typically incorporate sufficient accumulator capacity to enable the BOP to be operated with all other power shut down.

A ROV panel is where a ROV interfaces with the system

The whole point of that is this animation shows all three items together.
