  • Gas Turbine

    Hello, today i found out my first sea phase would be on the Celebrity Millennium. This ship has 2 gas turbine engines rather than diesel. Does this mean for my second sea phase I will need to be on a diesel ship and get a combined steam and diesel ticket? Thanks

    Erm.......GAS turbine you say........not steam turbine.....the clue is rather in the title

    Are they using the turbines for propulsion or as emergency generators? I know some cruise ones fitted them as back up generators as they have high power density and fit in odd little spaces, but wasn't aware anyone used them for main machinery (other than the military and some high speed craft obvs)...?....

    Send more details when you have them, sounds interesting.

    No I do not report things from here to them as they are quite able to come and read this stuff for themselves.

      Quite a few cruise ship's and ferries have them as propulsion
      Go out, do stuff

        Ahh okay I didn't realise there was a gas ticket! This website says that the propulsion is provided by 2 gas turbines and a single steam turbine- http://www.ship-technology.com/projects/millennium/

          Ok, that makes sense, you might get enough steam time depending on the size of plant etc, makes sense as there will be a lot of waste heat to recover

          I knew about the ferries using them for propulsion but don't know cruise ships where using them other than for emergency use.

          Not sure there's a gas certificate, so will need to check with your seniors once on board as to what time counts as either steam or motor or gas maybe

              No such thing as a gas ticket sorry....

                Do you reckon time aboard a gas turbine ship would count as steam time then?

                  You'll be better to ask once you're on board.

                    My understanding is that to sail on gas turbine vessels you must hold a motor CoC, so I would imagine that the time will count as motor time.

                      Quite an interesting setup. QM2 notably cruises on diesels but uses GTs for boost power to achieve 30kts.

                        MSN 1857 contains the answer...

                        5.5 Service on gas turbine ships Service on gas turbine ships can be used at full rate for both motor and steam certification. Engineer Officers holding motor or steam Certificates of Competency are eligible to serve on this type of vessel; however, some additional training related to the gas turbine machinery may be required for senior Engineer Officers.

                        Note that it would also require completing all the Steam parts of the TRB and sitting/passing the Steam EK exam.

                        Not sure whether gas turbine would count for both at the same time I.e. if counted for steam cannot be counted for motor...

                          A little late to the party... Currently on GTV Brilliance of the Seas... We have podded propulsion and our main generators are two GTGs - nominal load 25MW per side. Above these we have heat recovery steam generators outputting 32bar steam to drive a steam turbine (9MW). Also have a DG with scrubber system to burn HFO around the clock so I'm assuming what you will have is a similar set up. I haven't touched any of the steam section in the TRB as all the maintenance that has really taken place is safety valve overhauling and condenser cleaning.
