Twin Fin Propulsion System Delivers Better Performance

Through prefabrication, it took just 45 days for Caterpillar to retrofit its new twin fin propulsion system to the Polarcus Naila, a seismic vessel. The innovative twin fin system, made for diesel electric propulsion systems, provides both the increased cargo capacity usually associated with thrusters and the reliability and safety associated with conventional propellers. Add to that higher thrust performance, and reduced fuel consumption and emissions, and you have a sustainable solution that was delivered with limited downtime.

Caterpillar affects all aspects of global industrial growth. I’m looking forward to being a contributing member of this team.

I have watched the whole video and i am still waiting for an explanation about how this new system increase the performance. The only thing i saw is a big new fin that is supposed to increase the drag and give worse performance.

What a pleasure working on Cat propulsion system with Cat technicians.

I build repair and service Controllable pitch propeller systems. The benefit of this system is the compact design and ease of disassembly/assembly. If any component may need to be changed, it makes for easy change out. As far as performance goes, it probably isn't much better than any other system except for overall weight. Water borne bearings have to be changed more often with relatively low cost bearing material, it has to be machined though. With oil filled (EAL) vegetable oil filled stern tubes, the bearings are changed less and more run time without servicing. I'm an expert in this field. I have suggestions for this design and the only downfall of this design is draft, they hang pretty low.

you still don't say what it is, any more than the stupid vid.

[@andystevens7557]

TL;DR The Twin Fin system replaces the 2 existing Azmouthpods with twin stern thrusters, and twin propellers. It keeps the same maneuverability that the pods give, but is much more cost effective and reliable. It also means you can perform almost all of the maintenance while still in the water.

[@boomerrob9223]

No explanation of the system. Really?

[@vipero00]

Yah, but what is the twin fin system and how does it contrast and compare with what was OEM on the ship? So it's great but WTF is it?

[@SleepySkipper]

Yeah a lot of waffle but very little information!

[@eastofsuez]

The OEM thrusters were higher maintenance which meant more frequent dry-docking. The Twin Fin developed by CAT and partners provides a more efficient propulsion option for this class of vessel.

I hope Caterpillar didn't pay the person who did this video. Seems like it was done by some marketing weenie that has no knowledge of the product or industry. It didn't even define what a 'twin fin' is. After watching this video I know very little about the product. I feel so irritated at the video I am less inclined to seek out additional info about the product!

[@Xyb3rTeCh]

Couldn't agree more.

[@jamesbingham1007]

Yes, but you got some slow motion close-ups of work boots and hard hats.

[@peetsnort]

Exactly what I thought All fucking hype like the apple iPhone adverts I want to see the money shot

[@Justwantahover]

It's just an advertisement not a technical tutorial.

[@shortribslongbow5312]

What is the " Twin Fin System " and how does it work? Poor video.............

[@ellenharder]

Ow shit! This ship couldnt pay its bills at Damen shipyard so its been laying there for about 4 years now! Its a 2 minute bike ride from my home in the north of Amsterdam!

[@Justwantahover]

It's an advertisement, not a technical tutorial.

[@uncommonsense6635]

I wanted to see the sea trials and comparables. Cat is being a real dog on this one.

[@fridgemagnett]

Shame there was so little real information.

[@Justwantahover]

Imagine what that would cost. What a nightmare of a job!

[@jamesmerkel9442]

fast nearly bolt on retrofit nice.

[@nnkh8078]

Very good boys you smart 🤓🤓❤

[@dustinlaborde4537]

Watch the whole vide,o still have no idea what twin fin technology is ..... not a clue.

[@SolarizeYourLife]

No tubercles blades on the fins?

[@marvinkitfox3386]

No technical specs? Ok, here are some. The original ship was build in 2010 This retrofit was done in beginning 2014 i.e. The original design was SHYTE!

[@mitu-usa9121]

Im not clear about the concept

[@Flaaaaanders]

Twin fin is tougher. Engine in safer location. More hydrodynamic don’t have bulbous pod. If you know this already the video is nice

[@montymonty5040]

Nice

[@christopherscobie]

Cool

[@jamesmerkel9442]

electric power meant using bigger prop jack shit that is what they did nothing.

[@maretranquillity]

Very disappointing video, I know less about the "twin fin" now than I did when I started.

[@RU-zm7wj]

Look above you and everything is explained, maybe have an eye exam?

[@maretranquillity]

@@RU-zm7wj When I look above me I see the ceiling in my office--is that supposed to explain the Twin Fin? Reading down through the comments it would seem that I am not the only person needing an eye exam. Your post was just as useful as the video in explaining what the Twin Fin is. I did see another video that advertised itself as being about the Twin Fin, but it had been removed according to You Tube. Thanks for nothing though.

[@rightsideupvt]

Waste of time watching this. A bunch of suits patting each other on the back.

[@villageblunder4787]

What a terrible video.Cat should be ashamed.
