（ご質問１）
出発前から、荷役可能期間内の到着は困難と分かる場合はありますか？
Do you have some difficult cases to arrive in lay/can window before departure ?
（ご質問２）
その場合、荷役可能期間を再設定できますか？
Is it possible to adjust lay/can window?

Optimum Ship Routeing for Bulk Carrier
Post-Voyage Analysis
Based on re-evaluation of route, we show vessel
saved 159MT of fuel. This is made comparing
actual route versus the master’s route at his
intended RPM setting .
(B)
WNI suggested route with
better current condition
This was primarily because of RPM Optimization,
but also because of Route Optimization utilizing
current data.
(A) Fuel Savings due to RPM Optimization: 153MT
(B) Fuel Savings due to Route Optimization: 6MT
Total Estimated Fuel Savings: 159MT
(A)
M’s intended RPM: 70
(Eco Speed)
Suggested RPM: Min62
