    Enjoy this behind-the-scenes video of Endurance 658-14's CAT engine check. Our Service Operations Manager Geo Tamblyn goes into detail about a part of the HYG new yacht commissioning process. The first set of tests go from idle to full throttle at 100 RPM increments, with one engine tested at a time. At each 100 RPM increment, Bear, our CAT mechanic uses his software to check that the proper load is achieved, temperatures are correct, and fuel flow is proper. This is done to the max 2300 RPMs. These tests can help the mechanic to identify if the loads are proper, if the max RPM is being reached, and if the prop pitch needs adjusting. The 2 stop to full throttle tests ensure the optimal delay and speed of the engine, which protects the engines from hard use or unnecessary wear and tear. Once these are done, CAT will make any necessary adjustments and fine-tuning to guarantee an optimal cruising experience. 

    If you have any questions about this procedure or the commissioning process, reply and ask away! Geo will be happy to answer.

    This was a good video.  It would be great to see a proper pre-cruise engine room check procedure video.

    Thanks, Fred & Marybeth! That's a great idea; we'll work on putting something together about engine-room checks prior to cruising.

    Nice video, although I flinched when he just pushed the throttles to full load from a dead start.  

    What other systems on Hampton/Endurance are checked out like this?  For example: generators, stabilizers, chilled water ac, etc,?

    Hi Chuck,

    Great observation, and honestly I flinched a bit as well. I was pleasantly surprised that it was a smooth increase in rpm; it appears it is "Governed". As you seen in the video, no one was thrown back or uncomfortable during the test.

    Thanks,

    Geo

    Chuck, it’s part of the CAT procedure to test throttle response (timing) during the CAT start up process as part of the commissioning stage. The other components you mentioned go through “normal” testing like full load on the generators, seatrial stabilizers with mfg. We test and seatrial all equipment as standard procedure during the commissioning stage. Hope this helps and feel free to contact me with any questions you may have.
