Superyachts are fascinating craft to look at it But for me, even more fascinating, is the way they’re built and the engineering that goes into them In this video, we’ll take a look behind the scenes at how these boats are built And a look at some of the engineering that goes into building these amazing craft And for any aspiring yacht engineers, this video gives a look at another aspect of the job of a yacht engineer The boat is created as a 3D (computer) model From the model, hundreds of drawings are made which the builders in the yard use to create the boat in reality The hull starts life as a skeleton, with frames bulkheads and stringers, that are cut, assembled and welded together The actual skin of the hull is made from many small panels that are cut, rolled and welded in place Most of the small to medium-sized super yachts are built from aluminium You also get quite a number of fibreglass or composite boats at the smaller end of the scale too And on the bigger boats the hulls are usually built from steel And the super structure or the accommodation above the main deck is built from aluminium or composite material Once the hull and superstructure are complete, then the work starts with the installation of piping, insulation, electrical It’s really quite mind-boggling the amount of cables and pipe work that go into a boat When we get to the engine room later in the video, you’ll see what I mean To see the interior of these boats during the fit out is quite amazing It’s hard to imagine at this stage, just how beautiful it all looks when it’s finished There’s carpenters, plumbers, electricians, engineers, everybody working around each other It’s also equally impressive, just how quickly it transforms, from a workshop to a finished interior This is the crew mess on one boat For marine engineers, working on a yacht is quite a bit different to working on a commercial ship Here’s a small part of the audiovisual system. The entertainment system on these yachts is massive The yachts have quite large and complex audio-visual systems & computer networks. These take up quite a bit of your time Also the toys. Jet skis, tenders and other watercraft, these need to be maintained as well They’re are also something you don’t have on a ship This was going to be my bunk. But we were leaving in six weeks, I was starting to get nervous On some boats you need to share a cabin on other boats you have your own It’s another difference to working on the ships Sharing your cabin is not something you do on a ship Down the engine room there’s plenty to look at It’s like spaghetti down here, pipes and cables going everywhere But it’s a good chance with everything opened up, to follow where everything goes In the engine room, just like in the accommodation, there’s plenty of protection used Here’s a brand-new v16 MTU, nearly ready to be started up for the first time By far the two most popular engines used in super yachts, are the German MTU’s and the American Caterpillars My position on board, is Chief Engineer The engineer normally arrives in the final months of the build It’s a busy time, not just learning the boat You work together with the shipyards engineers, the classification societies surveyors Acceptance testing for all the systems and sea trials once she’s in the water Everything is getting tested. It’s a long ongoing process Finding faults, making lists, getting them fixed, ticking them off the list Also all the tools and spare parts need to be decided on and ordered in And finding enough room to store everything is always a headache Here’s one of the stabiliser fins, just prior to installation It’s only the passenger ships and ferry’s in commercial shipping, that have these They’re installed either side of the hull to cut down on rolling, when you’re underway. And also when you’re at anchor The zero speed stabilisers actually paddle when you’re at anchor, to stop the boat from rolling Here we are in the propeller workshop. We had to go down and check the fit of the propeller on its shaft They paint a blue dye on the taper on the shaft before fitting the propeller So you can check afterwards, for proper mating of the two taper surfaces And here they are after delivery, installed on the boat By now we were getting pretty close to the launch The final deck work was being done. And the painting was well underway, with plastic everywhere I think he’d lost his keys, up the exhaust… This was the crew’s office, for the duration we were in the yard Boats this size have normally two or three generators This boat had two and here they’re being tested, at just over 100 percent of their rated capacity Connected to load banks on the workshop floor By now the boat was almost ready to be launched Still a lot of work left to do after she goes in the water though Now it was time to try out these engines! Once we finally leave the yard, now it’s time to use the boat, for what it was build for I hope you enjoyed the video We’ve jumped over a lot of steps It’s definitely biased! It’s all from an engineer’s point of view But if you’re into the same sort of thing, hopefully it’s given you a better idea of how these boats are put together and if your mechanical minded and have thought of working on a boat I’ll put some links below in the description, where you can find more information on the pathways into this job Thanks for watching!
