Propulsion Systems Used in Modern Naval Vessels

Propulsion systems selection is an important part of naval ship design. These systems have always had to satisfy speed and ship-service power requirements. Nowadays, increasing fuel costs are moving such decisions towards more fuel-efficient solutions. Unlike commercial ships, naval ships operate at a variety of speeds and electric loads, making fuel consumption optimization challenging. Propulsion System choices for modern Naval Vessels depends on some criteria:
Traditional criteria
• ship speed requirements
• shock capability
• noise reduction
• infrared signature
Additional criteria
• change in operation requirements
• greater range of speed
• added mission flexibility
• longer periods away from base with smaller crews
• cleaner emissions
An emerging global macro-trend in naval engineering over the last fifteen years has been a decisive migration to ‘more electric’ propulsion due to progressively increasing electrical load demand and a focus on affordability. All-electric and hybrid electro-mechanical arrangements are routinely demonstrating merit since 1990 in the Royal Navy Type 23 ASW frigate and subsequent modern frigate programs. These include the Royal Navy Type 26, German Navy F125, Spanish Navy F110, Italian and French Navies’ FREMM, Republic of Korea Navy FFX-II frigate and Finnish Navy SQ2020 frigate programs.
Types of Propulsion Systems:
Combined diesel or gas (CODOG)
Combined diesel and gas (CODAG)
CODLAD (COmbined Diesel-eLectric And Diesel)
Combined diesel-electric and gas (CODLAG)
Combined diesel and diesel (CODAD)
Combined gas or gas (COGOG)
Combined gas turbine and gas turbine (COGAG)
Combined nuclear and steam propulsion system (CONAS)
Integrated electric propulsion (IEP)

i found this really hard to understand . What accent is this speaker ???

[@NoName-ds5uq]

Great explanation, thank you! I served on a ship with twin steam turbines and two shafts… A huge downside to them is their warm up time. From cold it would take 8 hours to get them operating.

No offence, but the voice is really bad!
Made watching unbearable.

Excellent video but it would improve it still would be if you were to use a better mic and / or get it closer to your mouth. The music could also be a little lower in volume compared to your voice. No offence, I just want your videos to be even better. Thanks.

[@ruthdilbeck2035]

Thanks for the clarification on several things. Following the accent is a little different though. It was a bit fun just listening to the talk.

[@telosfd]

Why don't they put external turbines like on airplanes? Unless they are vulnerable to any hit against the ship!

Combined diesel electric through azipod motors is the best way.
