The main advantages of electrical propulsion mode with power mating:
动力配套电力推进方式的优点主要有：
the reduction of lifetime cycle cost of vessels because of the fall of fuel
consumption and maintenance fees, especially when the vessel load varies greatly ‐由于减少了燃油消耗和维护费用，从而降低了船舶的寿命周期内的成本，特别是当船舶负荷变化较大时效果更加显著
the system could not be disturbed from a single accident, it also can optimize
mover (diesel or gas turbine)load
‐系统不易受到单个故障的影响，并且可以对原动机（柴油机或燃气轮机）的负荷进行优化
weights of diesels in high or middle speed are lighter
‐高中速柴油机的质量更轻
low occupation in the hull, the adding efficient load in the hull
‐船体空间占用更少，空间利用也更加灵活，从而增加了船舶的有效载荷applying electric to propulsion by cables, then can be not mounted together
with mover, which bring big flexibility of choosing the location of propulsion
‐推进可通过电缆供电，因而可以不与原动机布置在一起，这就给推进的位置选择带来了很大的灵活性
through the use of azimuth propulsion ,the movement of vessels improved
-通过使用全回转推进器，提高了船舶的机动能力
cavitation could be weaken due to the shorter transmission shaft and fixed
mover speed and regular water move made by azimuth propulsion, which can reduce the noise and vibration of the propulsion system
-由于传动轴更短，而且原动机转速固定，再加上全回转推进器使水流更加均匀，消弱了空泡现象，从而使推进系统的噪声和振动大为减轻
to ice-going vessel, when propellers crack on ice layer or floating ice, its laod
twist will change greatly ,electrical prolusion system has perfect power performance ,which can avoid parts load and accidental tripping phenomenon
-对于冰区作业船来说，当螺旋桨撞上冰层或浮冰时，其负荷扭矩将出现急剧变化，电力推进系统具有非常好的动力性能，可以避免发生局部过载并出现意外跳闸现
象
ice-breaking vessels should have great twist in low speed ,FPP propellers and
variable frequency drive technique satisfy the needs of ice-breaking
-破冰船要求船舶在低速航行下提供较大的扭矩，FPP螺旋桨和变频驱动技术可以
很好的满足破冰船的应用
For vessels requiring a maximum pull at low speeds, such as harbour tugs, river pushers and anchor handling tugs (AHT), the ducted propellers are generally the optimal solution.
管道式的推进器能够普遍的适用于一艘低速行驶但需要一个最大推力的船只，例如港口拖船，内河推轮和锚作拖船。

The nozzle used is the high performance HJ3-type nozzle designed by Steerprop. It combines increased bollard pull with improved free running efficiency. When compared to a traditional 19A-type nozzle, the achieved increase in bollard pull is 4 to 6 % and in high-speed efficiency approximately 15 %.
