Probably has costilier mantainance since its parts are all in one piece.

Lighter sytem: better top speed, worse acceleration, much more expensive to make it sturdier as the bottom one. Probably also needs much more maintainance due to it being slimmer and flimsier, but mainaintance is proabbly easier since its parts are "distributed". probably easier to make water tight(only need to put in water the parts that interact with water, and everything else goes into the boat).

The benefits are proably related to "How fast is the sheep going to need to go?"]]> 2021-10-07 11:43:38 UTC https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799472351 https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799480935 2021-10-07 11:47:46 UTC https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799480935 https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799484017 The first propeller is fixed and there is an external element leading the flow in a quite limited way. 
The second one allows rotation of the whole propeller, making the vessel more maneuverable]]> 2021-10-07 11:49:09 UTC https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799484017 jrby1015 https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799489582 The bottom of the boat has been altered to increase the flow strength running through the larger propellers. Additionally the fin and propeller have been combined, enabling the fin direction to change with the motor direction.]]> 2021-10-07 11:51:48 UTC https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799489582 https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799492429 The abb propeller looks more manoeuvrable, but it also looks more prone to heavy damage. The abb propeller is outside the ship and so it can be cooled directly by the water. The fans on the abb propeller are bigger. The propeller is more modular than the abb one, it is easier to mantain. The abb propeller is better for hydrodynamics.]]> 2021-10-07 11:53:14 UTC https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799492429 https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799493800 The second propeller looks more maneuverable as it can rotate and function as a rudder, and has a wider range of angular freedom, it also has ABB logo!
The second one looks smaller, less robust and less maneuverable.]]> 2021-10-07 11:53:52 UTC https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799493800 https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799494587 The top one is a simpler design, where the engine is inside the hull. The propellers are directed to the steers(?). It enables a possible larger speed (the engine is definitely inside the hull, therefore could be larger). 
The second design integrates the propellers with the steers enabling the ship to achieve even higher mobility.]]> 2021-10-07 11:54:15 UTC https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799494587 jrby1015 https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799494693 Although the second image appears to have a join which the motors can rotate on, perhaps having 4 smaller motors with rotating joints could enable smoother transitions in maneuverability? Other ideas could be altering the blade or motor casing shape, or making the bottom of the ship more round to increase flow into the propellers.]]> 2021-10-07 11:54:18 UTC https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799494693 https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799517930 Past history of same and imilar models. Where do they brake? how much time does it take for them to brake? In what situations do they brake(Do they brake faster in different weather or at different speeds[temperature, dust, atmospheric pressure])? What is the knowledge of those who operate them? How often do they maintain them?]]> 2021-10-07 12:05:07 UTC https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799517930 jrby1015 https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799518977 You could install sensors for each different part on every similar machine and continually measure the performance. This performance data could be sent to the cloud and analyzed with ML algorithms to determine if something is wrong. If the performance is behind similar machines, this data could be reported to an application that the manager has. With this data it could be sent back to ABB who could send a technician to tune up the machine before anything breaks.]]> 2021-10-07 12:05:35 UTC https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799518977 https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799521163 1) Measure parameters of the engine: current, voltage, torgue etc. and compare current values with the healthy values. Changes might mean possible damage.
2) Measure external factors that might cause damage, like air quality inside the housing of the engine. ]]> 2021-10-07 12:06:33 UTC https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799521163 https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799521582 digital twin of the motor]]> 2021-10-07 12:06:44 UTC https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799521582 https://padlet.com/hennapoutiainen/850szk6coxbh5qc5/wish/1799524909 Simulation

The decrease in efficiency could also be a lead.
