When required to do so, the EDP disconnects from the LRP and isolates the riser from the environment. Thus the EDP allows the MODU/WIV to safely and quickly disconnect from the subsea well and move away in an emergency. The EDP is designed to carry out its function while under load with a high disconnection angle.

In electrical engineering, a disconnector, disconnect switch or isolator switch is a type of switching device with visible contacts, used to ensure that an electrical circuit is completely de-energized for service or maintenance.
The micro ribbon or miniature ribbon connector is a common type of electrical connector for a variety of applications, such as in computer and telecommunications equipment having many contacts.

The main machine in the line was the GE-225 (1961). [5] [3] It used a 20-bit word, of which 13 bits could be used for an address.Along with the basic central processing unit (CPU) the system could also have had a floating-point unit (the "Auxiliary Arithmetic Unit"), or a fixed-point decimal option with three six-bit decimal digits per word.
