6. Starting Large Motors on board ships
Typical starting methods:
Direct On Line (DOL)
Star-Delta
Autotransformer (ATS)
Electronic Soft Starters
Electronic Frequency Drives (VFD)
What is the optimum starting method for marine application ?

7. Direct On Line Starting (DOL)
Direct On Line Starting results in High Inrush Current & Mechanical Shock
Motor Current
Inrush current % In
Motor Torque
Initial Torque % Tn
The high inrush current can result in voltage drops
The high mechanical shock can result in damage to the motor, load and transmission system (gear, belt, etc.). It can also require frequent maintenance.

8. Star-Delta Starting
Two steps starting: Y connected (58% Un), transfer to Delta (100% Un) t
U Y = 58% Un D Y Un
U Y
Transfer
point
Transfer to Delta by timer - open loop control, which may result in very high inrush current if transfer is done before motor reached close to full speed
Step angle of 30°

9. Autotransformer Starting (ATS)
The inrush current of the transformer in an Auto-transformer starter may be
too quick for the EVR to respond, resulting in a voltage drop

29. When To Use Soft Starters
Summary:
When starting current must be reduced to avoid voltage drops, due to the low ratio between motor / Generator power.
When starting torque must be reduced (mechanical problems)
When starting complicated mechanical loads
When starting sensitive loads
When starting high inertia loads (long starting time)
For frequent starting
Preventing over pressure and hammer effect in pump applications

30. Typical Applications on ships
Cargo Pumps (LNG), Ballast pumps ,Hydraulic pumps (power packs)
Large motors
Frequent starts
Chillers (air-condition & refrigeration)
Gas Compressors (FPSO)
Water injection Pumps (FPSO)
Thrusters
Fire fighting pumps
