Finaly an afternoon without rain.
A perfect opportunity to close the office door and open the window to shoot some pictures.

Three sisters, close to hand over to the customer, 'a' coastguard. Ships that sail 30 knots.
Four propellers, 4 x 1900 kW Caterpillar.
I write the operating manuals for them.





A not yet ready fast offshore supply vessel.
The yellow contraption on the aft deck is a swell compensated work platform.
The platform is lifted hydraulicaly so workers can work on offshore wind turbines. The swell compensation keeps the platform level with the turbine,
while the vessel below them can dance up and down in the waves.

Nice view from the office Ger, how does the swell compensation of that offshore supply vessel work ? is it by gyroscopic control ?

Ger- what are the dimensions of the CG Vessels? Length, Beam, Draft, tankage? How man crew on board during typical patrol operations?

Beautiful crafts right there, Ger!
The coast guard vessels look quick, and obviously are meant to be a bit intimidating. That motion-compensated work platform looks like a gas to work off of! Can I get a job working on wind generators in the North Sea, man?

Yo Quinten,
Not that I know everything but blue, white, & red -configured vertically- are the French national colors.
AFAIK.
Could have that wrong. Didn't hear it from me.

But I am sure
Ger was being discreet (hint hint)
anyway, since these vessels have yet to be sent to their new owners. wink

The CG vessels are for one of the island states in the Caribian sea between where the dope comes from
and where it is supposed to go to.
They each have a fast (waterjet drive) daughter craft, launched from a ramp in the stern.

About the work platform on the supply vessel, I have to check the name of the sub supplier.
They have an informative website. I'll post tomorrow.

Peter, you may know the bridge across the Merwede in the A27 at Gorinchem.
It's in the news every morning. Congested traffic...
The yard is Damen, answering Quintens suggestion below. That's not a secret. wink

you could be right , I'm seeing the blue color as black ?
But as the stripes are vertical nor horizontal , all bets are off .

Signal flags on the yardarm and bow , I think say D(amen)?

Yes, 30 knots is fast. My Dad served, during WW2 in the SWPA, on a Modified Leander Class 6" cruiser. Parsons geared turbines; 4 shafts; 72,000 S H P; 7,105 ton displacement; 32 1/2 knots.
British built!

30 knots is indeed fast. The older normal cargo ships I sailed on in the nineteen-seventees had a cruise speed of 16 to 17 knots.
The later ones 21 knots.

To answer some questions:

The three sisters in the pictures are 50 meters long, 9 meters wide; draft 3 meters.
Do a google search on "SPA 5009". SPA means StanPatrol.
The basic design is standard. The vessels are customized per order.

The blue supply boat is 51 meters long, 9 meters wide. Draft also 3 meters with a margin according to the loading conditions.
Google for FCS 5009. FCS means Fast Crew Supplier.
Here also the basic design is standard. The vessels are customized per order.
The hydraulic work platform on the 51 is made by Palfinger.

Both vessel types have a `sea axe` bow type. This bow type plus the shape of the hull
below the water line results in higher possible speed in rough sea state and prevent `planing`.

Two hundred years ago, shipyards were turning out fast frigates and sloops for various navies whose purpose was to intercept pirates and blockade runners.

Not a secret for sure. There's a nice picture on the Damen web site of Mr. van Oord signing a contract with the defence minister of Trinidad and Tobago for 12 patrol vessels .... quite a nice contract, I'm sure!!

I worked for a company once that had a shipyard. They lost so much money screwing up the builds and the estimates that, every time the news came out that they had won a contract, the stock share price went DOWN ....

For some film about a similar vessel plus daughter craft [click] here.
Its a Greek coastguard vessel in the Aegean sea.
The victems are refugees from who cares where who happened to need some help...

Do not try to read the Greek teksts. The footage after the 40th second is good enough.

Do any of the customers of these ships fit them out with ASW weapons, such as depth charges, MAD, or homing torpedoes?

Looks big and fast enough to take on the normal diesel submarine that might be sneaking up. Although I'm sure that the ASW weapons systems would cost more than the ship .... !

@ASW weapons@

You want to buy one, Lannis? laughing

Basically every vessel is a platform which can be fitted with different systems for different purposes, civilian or military.

The yard here - my location - does not fit weapon systems.
One of the yards in the group which also builds for the navy, does. This has to do with licenses, security etc etc.

My team describes vessel functionality only. Not - also not if fitted - weapon systems.

Ger, what do you reckon of this. HMS Ariadne, Abdiel class minelayer cruiser, launched16/2/43. Displacement 2,650 tons, std ; 4,000 tons full load. Two shafts, geared turbines, four Admiralty three drum boilers. 72,000 shp. FORTY knots.
In 1944, she was attached to the US Seventh Fleet in the Pacific.
At that time, Dad was serving on the LSI HMAS Kanimbla, at Leyte ( Philipines ),yes, Dugout Doug needed the assistance of the ROYAL Australian Navy for his " I shall return "( the Kanimbla was one of several HNA Ships involved in this operation )
Anyway, at one time the Kanimbla was hove to close to the Ariadne, which was just sitting simmering. Dad said, that in the space of seconds, the Ariadne got a call to be somewhere. The funnels belched, the stern sank, and she had the bone in her teeth in yards! Like a speedboat, he said!
The greatest display of horsepower Dad reckoned he ever saw!
British built!

72000 hp is more than I ever sailed with. I learned the 3-drum boilers at school but never saw them.
They were teached as a typical navy boiler due to the low height and compact shape.
I only sailed diesel propulsion.

That much power on two shafts only is remarkable.
You need enough propeller blade area / diameter to transmit that much energy to the water since hydrodynamics limit propeller tip speed and thus rpm.
That's one of the reasons the fast patrol vessels here have four shafts / four propellers (D = 1.5 meters in this particular case). The draft does not allow for large diameter propellers.

I hate to sound like I am compensating for something, but my ship would do in excess of 80,000 shp per shaft on 4 shafts (during sea trials - not the norm). The torque would rotate the longest shaft something like 1.5 times between the reduction gear and the propeller.

Steam is where its at. Never could get used to diesel propulsion, seemed too new and cutting edge for me. smile

Warships are a special category, they have to have as much power as it's physically possible to twist the shaft with. Everything they do needs massive amounts of power - chasing the enemy, running from the enemy, dodging a torpedo, recovering aircraft; in a war, everything really IS a life-or-death situation. No worries about fuel consumption expense, and if you have to sail into a hurricane or typhoon as part of your tactics, the huge amount of power generally lets you stay alive in there ....

That's a lot of power.

What kind of ship was that, Geoff?
An aircraft carrier?

A navy engineer (I'm merchant marine) once explained it like this:
Two shafts are what we need for normal operations.
Best efficiency, and handling at cruising speed.
The two other shafts give us what an afterburner gives a jet fighter.
Get the h3ll out or get the h3ll in.

Quote:
speaking of diesels ... they say 'Bigger is better'

That's the engine type we call "cathedrals" as used on normal long haul cargo ships.
The engine drives the shaft directly; no gearbox, at 100 - 130 rpm.
The engine can turn CW and CCW for forward sailing and for manoeuvring astern.
These ships go deep (draft) so a huge propeller on a low rpm speed is possible, giving best efficiency.
Plus: It can burn fuel as cheap and viscous as asphalt (when it's cold).

What amazes me is that you can scale up a model aircraft engine to something millions of times its size, and end up with one of these. It's like scaling up a mouse to be an elephant - it shouldn't work!!

But this thing has pistons and a crankshaft and flywheels and everything just like a tiny two-stroke diesel. Must be a job replacing main bearings or big-ends!

USS Enterpise. Eight 150 MW reactors feeding 4 engines and a 1200 psig boiler (taken out when I was there) as a back up to the nuke plants, plus a couple of diesels (not for propulsion) for good measure.

They don't build them like that anymore. The ship was obsolete when I was on her in the early 90's, but I would take her over the new electronic gizmo ships now. However, I was on the liberty ship in San Francisco (SS Jeremiah O' Brien) while they were turning the shaft and must say that I think I like triple expansion engines over a turbine. I envy your career Ger B - I love marine engineering but never had the fortitude to go back after my Navy days to get my degree and license in it.
