General
1.1 Objective The objective of this report is to present the prospective fault current levels that can arise in the electrical power system on board MV Marble & MV Front Granite with particular respect to 440V system. Maximum short circuit contribution is calculated in order to verify the system withstand ability, particularly the switchboards and circuit breakers making and breaking capacity. Minimum fault currents are used for protective device co-ordination. Calculation tool is SKM Power Tools for Windows (version 6.0.3.2). 1.2 Scope This report covers the short circuit calculations on electrical power system on board MV Marble & MV Front Granite Scope includes:

Calculation modes and assumptions The power system has been implemented in SKM Power Tools for Windows and calculations are done according to IEC 61363. Maximum fault current has been calculated to verify system short circuit ratings. Minimum fault level (phase-to-phase fault current) is used for the relay co-ordination. The following cases have been calculated: •
Maximum fault level
•
Minimum fault level
Case 1: Maximum fault currents (Ballasting / Deballasting) •
All 3 generators are in operation
•
All Ballast pumps are in operation
•
All Ejector pumps are in operation
•
Cooling & Ventilation are in operation
•
Engine auxiliaries are partly in operation
•
Bow thruster is not in operation
•
Mooring system is not in operation Some conservative assumptions have been made: -
The z” of the motor power more than 100kW is set to 0.16pu and r/x=0.36.
-
The z” of the motor power less than 100kW is set to 0.2pu and r/x=0.42.
Case 2: Minimum operation Minimum fault level is used for setting of protection relays. System configuration according to Case a, with following exceptions:
Doc. kind Title
•
Sustained fault current from one generator (3 x In) is used for calculations.
•
No motor contribution
