Figure 23 

ROV-type Subsea Environmental Cap and Dummy Connectors, flying and flanged types.  

 

Note that there  is  clear  subsea  visible  differentiation  between the  Environment  Cap,  and  Dummy 
with  open  circuit,  looped  with  wire  or  resistors.  Labels  are  added  for  this  purpose  (not  shown  on 
these images). 

9.5 

Live Mate / De-mate 

The connectors are not designed to be mated or de-mated while electrically energised. Depending 
on the type of electrical load, the following advice should be followed. 

 

Danger!

 Risk of death from electric shock due to exposed live pins, e.g. factory or top-side 

system test and unmated receptacle is energised.  

Ensure all test procedures are followed.

 

Communication channels and protocols are observed.

 

 

Caution

.  Risk  of  material  damage.  The  maximum  number  of  live  mate  /  de-mate 

operations under any of these conditions is ONE only. There is a high risk of damage 
to both plug and receptacle connector that would render it unusable. 

 

Resistive loads 

Mating the connectors should not lead to any damage to the sealing mechanisms within the plugs. 

Following this de-mating procedure, testing should be carried out on the connector to establish if any 
damage has occurred. Under no circumstances shall connectors be partially mated with power on. 

Capacitive loads 

Mating with power on will lead to an in-rush current. The magnitude of this in-rush current will depend 
on the capacitance of the circuit. It is very important that the in-rush current is no more than 100A 
for 5 seconds. 

Inductive loads 

Mating the connectors should not lead to any damage to the sealing mechanisms within the inserts. 
De-mating 

must not be attempted 

as there is a risk of high back EMF’s which will cause damage 

to the seals and insulation within the inserts.
