[ATTACH]4343[/ATTACH] New T Parker Host boat Ms Janet for the CSX coal run in Baltimore
Old Delta/Crosby boat.
I have to question the HP that is listed for this Tug (Old Crosby Force). From what can find she has Detroit Diesel 16 V 149 T.I.B. and they claim 4000 HP. Supposedly, she only has 1 3/4" wire, which seems a little small for a 4,000 HP Boat.
How in the Hell do some of these GOM Boat Owners come up with the listed HP? I guess they are using Common Core Math!
It’s Liar’s HP.
Most people would call a pair of 16-149s about 2400 hp.
yes and that’s generous. My boat has well over 10,000 then.
The funniest shit is looking over their HP specs for boats on the Crosby site.
Most old 165’ OSV’s I worked on that were built in the 70’s had 149’s. The engines were always rated as 900 hp a piece.
That was for the older NA version correct? I think the turbo version (depending on configuration) was 1500-2000 HP or something like that. Granted I don’t think the turbo version ended up as main propulsion on too many vessels. I certainly have not seen turbo 149s on any old workboats (mainly tugs) I have been on.
Crowley always sold the Invader Class as 9,000hp. They may still. . . I remember in Lake Charles when I was working down below between SJ runs, a Navy surveyor was onboard looking at a typical Invader for a job we were bidding on. He was looking at the name plate HP of the 20EMD645s and asked me how 3,600 x 2 equaled 9,000. . . I told him that he might want to talk to chartering. . . . we got that job anyway, and I even got to participate, towing two SL-7s from Philly to NOLA for conversion. . .

That’s a good estimate…
I’m currently working on a vessel with 16-149s and our hp is classified as 2560.
I’m only on my second hitch on a new boat, and in the wheelhouse again after three years in the ER with a different employer (because of that I have not gotten involved at all in the er here). I’m curious and will ask the chief if these have turbos.

I think these outfits combine the HP of the steering motors, capstans/towing machines and dishwasher.
I remember running those old Moran/Curtis Bay boats with the 278 diesel electric plants and forty years after they were built, they were still billing them as 1750 horsepower. The chief and I laughed about that one often.

Just walked my lazy ass down there and looked myself. Yes these are turbocharged.

They go through the vessel and get the horsepower rating from every data plate on every motor, compressor, engine, microwave oven, fan etc. Add all that horsepower together and multiply it by the peak, maybe 1.5. There you go, the HP of the vessel. Cha-ching$$
I think all the ship assit tugs use the total hp including the mixmaster, a/c units. Bollard pull is probable more accurate not always being operated on the same power levels that the test were done on.
It’s coonass HP. Divide it by 2 to get a number that’s close to what the boat actually has.

Coonass HP = Indicated HP as opposed to Bhp used by the rest of the world.
In fact most of the world has gone to kW as the universal measurement of energy and kN as measurement of force.
thought you left?
Well, you know, we Americans are still using imperial measurements because we can. Screw your eurofag metric system!!

along those lines, just got an ecdis installed on board here. Doing the course next month so hoping to learn a lot…anyway, depths are in meters and I was told there’s no way to change that because that’s the IMO standard, much to my chagrin.

It’s real easy to figure out, 0 meters is the same as 0 feet. Your depth under keel should NOT equal 0.
I ain’t even got a 6-pack and I know that.

So the American military are eurofag’s?
