Operational fuel efficiency 能源效率

Increasing fuel costs inspire ship owners and operators in finding ways to reduce fuel consumption. In sight of recent developments in emission regulations, ship owners benefit from the proportional reduction of emissions with reduction of fuel consumption. For existing ships, a significant amount of fuel can be saved by improving the operational conditions of the vessel. The expected additional fuel savings can be as high as 5%.

逐年上涨的燃料成本迫使船东和运营商寻找降低燃料消耗的方法。从现有排放规定的发展来看，减少燃料消耗进而按比例减少排放的做法也会使船东受益。对于现有船舶来说，改进船舶航行条件将会大大降低燃料使用，预计额外的燃料节省可以高达5%。

Essential in fuel savings on board is crew awareness. Motivating the crew to act and react to fuel consuming conditions is essential. Important in this is displaying the effect of some operational choices on the ship performance.

在船上对于燃料节约最主要的是船员们的意识，同时激励船员们掌握燃料消耗条件也是非常重要的。即向他们展示一些航行条件选择对船舶性能的影响。

Navigational conditions in which fuel is wasted are:

燃料浪费的航行情况包括：

• Large speed variations 较大的速度变化
• Applying full power in shallow or restricted water 在浅水或限制水域使用全功率
• Too sensitive auto pilot setting which initiates frequent rudder angles 导致频繁更换舵角的过于敏感的自动驾驶
• Suboptimal trims 次优纵倾
