Fuel Cost Awareness

Question:

WHY Ship Efficienicy?

2

3

Increased fuel-efficiency of vessels and main propulsion systems
Identification of consumption components
Before improvements can be implemented, sources of consumption need to be
identified.

Consumption
Design Reasons
Non-optimized
machinery design

Non-optimized hull
design

Operational
Reasons
Reasons related to
charterers (e.g.
scheduling, waiting
times at terminals
etc.)

Reasons related to
owner (e.g. voyage
execution, trim,
maintenance)

4

Design Reasons
Efficiency adjustments vs. operational
requirements - propeller and bulbous bow
optimization


The new bulbous bow design reduce
the form related resistance and
optimize the wave resistance for the
new operation profile.



The second benefit of the new bulbous
bow installation is a reduced total
resistance of the vessel which enable
additional optimization and saving
potential in way of the propeller
design.

Operational Reasons – what parameter can we influence
Controllable Effects, e.g.:
-

Trim
Draft, Ballast
Rudder angle
Hull Condition
Engine Performance
Auxiliary systems
Routing and scheduling

Uncontrollable Effects, e.g.:
-

Wind
Waves
Water Depth
Ambient Conditions
