now the question is.... how do we fit it in a BUSA????

BIG motor.Love to see the start motor.Or is it air start?

Air start to each cylinder, either way. Cam shaft slides along and allows engine to run either way. Big ships have reversing engines, no transmissions. That's one reason they're slow to stop!

Yeah have played that game trying to get ships out of slipway in a tidal river system (Cairns).
When it does not work first time round & you need to return to fwd thrust it gets bloody hairy as the boat starts drifting towards the dock pylons whilst engine direction is changed.
Especially when said boat has just had an $3 million refit inc $1 million in paint, stress, what stress.

Even with reversing g/boxs some are prone to stall when direction is changed to fast...

I worked on fishing boat engines and in trucks at universal diesel,Darwin.Before and after the cyclone.Only gardeners & Perkins,man diesel and stuff.

Awesome post. Any more photos?

Sorta makes you realise with all these ships in the world how reliant we are on fossil fuels and how we complain when we fill up our cars and bikes. We must have a lot of reserves to keep this society going.

For that ship it works out to 38 200l drums of heavy fuel every hour.
The figures are scary!
And the volume of exhaust gases coming out the funnel makes a joke out of the controls we put on our car (and bike) emissions!
But there's still no better way to move 200,000 tonnes of cargo around the world, so I guess they're here to stay (keeps me in a job, too!).

i saw the swedish company fitting these engines to one of these ships a few years back ,awesome show

This ship has been VERY unlucky, from the very start!
Just before the owners took delivery of the brand new ship from the shipyard, a welding job on the main deck led to a fire that totally destroyed the almost finished accommodation quarters and all the navigational and electronic equipment on the Bridge.(the whole 'block of flats').
They decided to use the superstructure (accommodation/bridge/funnel) module being fabricated for a subsequent sister ship to replace the burnt out module on the Emma Maersk. The entire burnt-out module was cut off at deck level and then sold to a nearby recycling company for demolition. The replacement module (completely fitted out with furniture, equipment, wiring, galley, refrigerator chambers, plumbing, exhaust/induction systems, electronics, etc, etc) was lifted and placed onboard in one 1200 tonne lift. The lost time due to the fire was only four weeks.

Sort of like buying a brand new Busa, the only one available, and it then catches fire in the dealers workshop while doing its pre-delivery inspection? You'd have to be a little pissed off?

(PS I hope you guys find this stuff interesting? I know its not to do with Busa's, but it is a machine/engine/vehicle?)

Keep it coming mate... thought we hate to admit there are other interesting things about other than busa's LOL

Keep the photos coming Cap. It's about time we had a member with an interesting job that can post pics.

Top posts Captain!!! Is it true the fuel these ships use is like a soup? And not sure if its true but a mate told me yes ago that the ship motors can be "two stroke" to save on weight?

Yep, you're right. These big ships run on heavy fuel which is un-refined and cheap. At normal temperature it's very thick and heavy, and it smells f***** aweful! The ships heat it up, to make it thinner, and then cleans it through centrifugal purifiers. The sludge is stored in tanks onboard. This is a daily process to keep up with the daily consumption. The big ships engines are reversing (they can run in either rotation) but they generally can only start and stop and start again on diesel fuel (we call it gas oil). So when the ship approaches port, the engineers start to merge the gas oil in with the heavy oil, until its eventually running on gas oil only. Then it can be stopped and restarted. There are big accumulators of compressed air to start the engine, but usually only enough for 5 or 6 starts. Then you have to wait a long time while the compressors recharge the accumulators. If you stop, then go astern, then stop, and go ahead - that's 2 starts - you've only got three left! That's why big ships don't like to stop, and sometimes can't stop. Coming into a port and maneuvering into a wharf needs a bit of thinking out! As a Pilot, (12 years i did it for) the first thing you ask the Captain is 'how many starts, and where's the main engine start air guage!' Sometimes going from ahead to astern the engine won't 'catch' - you've just wasted one start. No wonder Pilots burn out early and have an alcohol problem? Some of the big engines use individual piston braking with compressed air used to bring each piston to a stop, then the same air pressure starts the engine rotating in the opposite direction. At the same time the cam shafts are moved along by hydraulic rams to another set of lobes, the fuel is injected into each cylinder, and away she goes. Easy!
