A question for engineers:
Large container vsls designed for speeds of up to 25-26 knots, and B&W engines of 75.000 HP to 90.000 HP (10 or 12 cylinders).
Max rpm 104 / 26 kts
Eco rpm: 80-84 rpm / 20 kts
The recent trend is to reduce speed to some 14 to 16 knots, which actually is manouvering speed.
- What is the long term effect on main engine?
- Once per day running on full navigation speed - can this help?
- Any other comment or advice.
