I found the order and details of the engines. Where is Engineer as I would like his views on them.

MaK power for BC Ferries
MaK 8 M 32 C diesels will power the three Super C Class ferries on order for BC Ferries at Flensburger Sc hiffbau Gesellschaft (FSG) Germany. The double ended ferries will be 160 m long, with a beam of 28.2 m and a draft of 5.75 m. They will carry 1,650 passengers and 370 automobiles and have a crew of approximately 35. They will be dlievered between December 2007 and June 2008.
With more than 750 engines sold, the MaK M 32 series has gained a leading position in its market segment. The M 32 C, produces 500 kW per cylinder and has proven successful as a prime mover in diesel electric propulsion applications.
In the Super C Class ferries, for example, the four MaK 8M 32 C generator sets in each ship jointly supply the electrical energy for the currently operating unit of the two propulsion motors (each of 11,000 kW), all the auxiliary systems and the comprehensive facilities available on the ships.
At an engine speed of 600 rpm, a total of 16,000 kW is available at the main switchboard. Even with only two generator sets active, a cruising speed of 18 knots can still be maintained.
In addition to the low operating costs and the high level of reliability, another important feature of the MaK engines is their low emissions..
The engines meet current IMO emissions standards and can be retrofitted with the Caterpillar-developed ACERT system to meet expected future requirements for even lower emissions. For this purpose, FlexCam Technology (FCT) or SingleFluid CommonRail (SFCR) are available. The employment of the FlexCam Technology, for example, reduces the soot emission in the part-load range to the point where it is invisible and lowers the NOx emission by a further 30 % below the current IMO limiting value.
The decision of the shipping company and the yard in favor of MaK 8M 32 C generator sets from Caterpillar Marine Power Systems is the result of many years of successful cooperation between the partners. As early as 1970, BC Ferries had good experience with MaK propulsion systems following the conversion of two ships and has since equipped a large proportion of its new ships with MaK or Cat engines. The Flensburger Schiffbau-Gesellschaft also mainly employs the proven MaK drive systems in their well-known RoRo type ships.
MaK Deutschland (as the partner of the Flensburger Schiffbau-Gesellschaft) and Finning Power Systems (as the Canadian partner of BC Ferries) have cooperated extremely closely on the project.

Wow, is 600rpm supposed to be a really low running speed for these engines? and then only goes 18 knots (33.6 km/h) as a service speed? 600rpm is a lower idleing speed than my car! Unless there is a difference with the car engine revolution and a ferry engine revolution that is confusing me...But wow, they seem to be getting really high end engines for these 3 ferries though! It's making me more excited!

[NMcKay]

its only generating power for the electric engines. and so they can run @ a low RPM, but still my car idles @ 800 Rpms, and yet the truck engines top out @ 2000 RPms

[hergfest]

Diesel engines rev lower than a car. Check out a Diesel Dodge and look at the tac, it redlines at 3k RPM.
Doesn't BC Ferries run the MAK engines on some of their boats? I remember reading somewhere that they have been very reliable.

[Scott (Former Account)]

All C-Class, and V-Class run the German MAK Diesels...

[NMcKay]

Reliable. but the parts take 6 - 12 weeks to ship in from germany. same with our engines.

[cascade]

I would like to know what Gearboxes they are using - as BC Ferries seems to have a lot of trouble in this department.

It looks to be about correct level of power - need to see the pitch on the props and how many blades they will have.

Spare parts - they are included in the contract - engines. I see that CAT are also in with some controls.

Here is the link to the engines

www.mak-global.com/prod/prod_comm_m32.php

MaK and Caterpillar joined forces a couple of years ago.
Cats pretty well only go up to there 3500 and 3600 series engines (3512's on the Main, Bowen, PR queens, and 3606 on the spirits for a stand by genni).The MaK's come in for bigger ships. The M8-32's are the inline 8 cylinder of the models. Here is some facts on marine engines for you all.

Marine diesel Engines are grouped into 3 types,

SLOW SPEED or Crosshead Engines: top RPM is around 100-110 RPM full speed. These are very large engines usually fitted in large ocean going containerships, tankers, frieghters. piston diameter is usually anywhere from 500mm to 1000 mm (1 meter) across. These are very tall engines with a crosshead and slipper between the piston rod and conecting rod. These engines are always of the 2-stroke cycle and usually burn bunker C or "heavy oil" as fuel. Horsepower is now up to and over 100,000 HP! BC ferries does not use any ships with these style of engines. Here is a picture

www.dieselduck.ca/images/engine_room/Machinery/B&W_12K90MC_75000hp.htm

Medium Speed: Engine speed usually can range between 300-1100 RPM. Queen of Nanaimo has (2x) 16 cylinder Mirrlees KVSSM Main engines turning at 325 RPM full speed. Usually fitted in ferries, large fish boats, some containerships,freighters, or tankers. Very useful in a ship where overhead room above the engine is not a great hieght as cylinder heads,pistons, con-rods, and liners do not need much room to be removed. This way more can be stored in the ship as the engine room is not as high. These engines are of the 4-stroke cycle. Here is a picture

www.dieselduck.ca/images/engine_room/Machinery/mak_m32.htm

Highe Speed: the rest of the field. Caterpillars, Detroit diesel's, MTU's, Cummins; Mitsubishi's etc. These can be either 2 or 4 cycle engine depending on the design. RPM's generally up to 6000 depending on the engine but marine is normally around 2000 or less. Here is a picture or go look in your dad's dodge ram

hope this is of any use

Odd looking...quite a bit different than the one BC Ferries had.

If I recall correctly, the manufacturer of the Gearboxes on the C-Class is L&S (Lohmann and Stolterfoht)...

Harbourlynx Has Medium SPeed Diesels with Twin Turbos... :>

I was under the impression that they were using (2X) 16 cylinder MTU's. These are actually rated as high speed diesels. The pacificats had (4x) 20 cylinder MTU's with 5 sequential turbochargers per engine. The Quinsam, Howe Sound Queen and the NIP all have the MTU 12V2000's with twin turbochargers.

[NMcKay]

your right. 2x 16000 Series MTU @ 2000RPM Maximum,

[BrianWilliams]

Forgive this most elementary question:

Is the power transmission diesel-hydraulic or diesel-electric?

[noleaksyet]

the super C's will be diesel electric

[cascade]

Engineer - you maybe able to answer this - but does BCFS have standard Bridge equipment - or is it a mixture of different kit?
As I wonder what type they will install on the new Super C's - of course the engine management system - linked to the bridge. This is normally different than the MaK engine brand.

This has been a problem for many years ordering different types of equipment for each new vessel. which in turn costs way more money to stock parts for every ship.
I think after all these years they are slowly learning, but wait and see, in the end I am sure there will be a whole new basket of goodies .
The choices are made my the powers above, we give them input, but it always seems to get lost by the time the ordering happens lol

[Engineer]

diesel electric
Yip it gets my vote, The Cumbie is Diesel-Electric and it is great to work on.
Our Bergen Generators run at 900 Rpm and produce 1.5 megawatts of power each.
4160 Volts.

[NMcKay]

yeah. but they burn too much gas because the engine has to be @ max power to generate power

[Political Incorrectness]

is this the C class HL Teen or the Super C's and what is up with companies not choosing fuel efficient purpolsion systems?

They look better than the drawings on BC Ferries' website. Those enclosed areas on the BC Ferries concept drawing just look ugly.

[Doug]

Harbourlynx Teen: the reason they use diesel electric is because it reduces fuel consumption and emissions. Have to be at full power?

I was wondering what that thing over the upper car deck was...seems like a few of the vessels built at Flensburger have that. Any ideas? I hope they don't stop using the upper loading ramps....

[NMcKay]

yes. the engines have to be at Full RPM all the time to generate power to the electric engines. just like the Trains do too.
