Project Overview
Major Project Challenges
Maintain operations
during construction
“Bumpless” transfer of
power
Mooring/Berthing of
numerous ships types
General Electrical Requirements
Ship power requirements
7.78 MW @ .8 PF = 9.73 MVA
6600 V
Limit voltage drops
Grounding
Ship Power Requirements
Bumpless transfer achieved by
One diesel generator (SSDG) on line
Momentary paralleling of shore & SSDG
Match Phase
Transfer to Shore Power (Green Power)
Ship power demands
Hotels Loads
Shipside Oil Unloading Pumps
Crude Oil Washing (COW) Pumps
Ship Power Requirements
Voltage Drop Analysis
Assure voltage within allowable limits
Operating voltage range 6600 to 6800
Calculated voltage drop below 5800 v
due to COW pump start
Ship controlled LTC transformer
Composite Voltage Profile
Grounding
Ship grounded to earth
Hull & earth same potential
Ship & earth bonded
Ground within power cables
TOUCH POTENTIAL
Between cable and
ship
Arching during
ground fault
conditions
Touch potential
