The KC-135 & VC-10 (both four-engined airplanes) have both provided sterling service as tankers with four engines, and indeed there is a large fleet around the world of converted 707 tankers (707’s & 747’s in Iran’s case)…all of which have four engines.

:confused: Like TriStar, I would think. :confused:

Self righting RNLI craft = nice. but still replace the air with water, she sinks. Think that’s whats happened when the Portrush boat had an argument with Rathlin Island. ( Happy to be corrected if wrong)

Nice idea though, a 1000+ft long carrier self righting after being hit. Over 6000 inside thought might be a little ill after.:)

You can’t get the air out of foam 😉

As for shipsize, sure, currently GRP vessel are limited to about 500 tons, but those ARE minecountermeasures vessels – which are more likely than other vessel to face detonations close up – and some FACs (e.g. Visby)

Anyway, even for (very) large vessels: if you foamed up unused/unusable spaces, that would help maintain buoyancy should the hull ever flood. May just be the difference between sinking or limping back to port…

i just found this on another forum,
does anyone know what that huge white block is that is being installed on the Varyag? :confused:

i think its a boiler, but i dont know :confused:

http://club.china.com/data/thread/1013/2715/97/75/6_1.html

Varyag would have a(the) late(st) model KVG-3 boiler (see below). The white block you are referring to is not even vaguely reminiscent of a KVG-3 type boiler. In fact, there is nothing in the pic(s) to suggest it is being installed on board the Varyag, or even intended for installation on it, or is even on the dockside along the Varyag. Looking at the two photo’s accompanying that pic, I’m more inclined to think it is a cooling element associated with the fixed planar phased arrays.

CONVERSION OF MARITIME BOILERS FOR STATIONARY POWER GENERATING PLANTS
—————————————————-

The Special Boiler Design Bureau, which boasts extensive experience in developing maritime power generating plants, has developed a number of steam boilers of unique design on the basis of ship’s high-pressure boilers. The technical characteristics of some of the steam boilers make them of interest for application in stationary power generating plants. Necessity prompted SKBK’s designers to recognize the feasibility of using maritime boilers on the “ground.”

The use of such plants began in 1961. With the accumulation of experience, high-pressure boiler designs offered increasing reliability and production efficiency. For application in stationary power generating plants the maritime boilers were decertified and modified in accordance with the requirements of the inspection services of Russia for stationary conditions.

These plants are characterized by a number of specific features. One such feature is the unique principle of operation of the high-pressure boiler converted for use in stationary power generating plants. For example, this type of boiler utilizes outlet gas energy for delivery of air to the furnaces for fuel burning. A gas turbine drives the compressor which pumps the air. The turbine is connected to the boiler gas line downstream of the economizer and operated by flue gas which has already transferred a considerable part of its heat energy to the boiler heating surfaces. It is remarkable that the compressor and gas turbine are integrated into a common turbo supercharger. The free air drawn by the compressor is heated during compression. Then, the air is supplied through the air duct to the boiler casing. The casing is rated at the compressor’s maximum pressure. After passing through the inter-casing space, the air is forced through the air nozzle to the boiler furnace and mixed with fuel atomized by the injectors, thus providing its normal burning. The fuel combustion products, or flue gases, pass through the gas-cleaning system, removing any hard particles, and enter the gas turbine. In the process it transfers part of its heat to the heating surfaces in the boiler furnace and gas duct.

Thus, excluding unproductive losses by optimizing the working process, the SKBK has achieved the high productivity and efficiency of ecologically clean boilers.

It should be noted here that depending on the boiler load and external air temperature it is possible to observe insufficient or excess power developed by the gas turbine. In this case, insufficient power is compensated for by an additional steam turbine and excess power is avoided by releasing air supplied by the compressor through the air control valve.

The feed water is delivered to the boiler through the water economizer. From there it flows into the steam collector through the feed tube to the slip pipes. The slip pipes are located behind the screen, close to the steam and water heaters. The steam generated in the screen row and convection bank of tubes enters the steam superheater and is fed to services.

Structurally, the high-pressure boiler is essentially a compact vertical 2-head boiler with a vertical heat superheater, an economizer and one-side gas flow.

In consideration of actual operating conditions, the SKBK made the boiler control system fully automatic. Thus, the boiler features high dynamic characteristics: the increases and decreases for several minutes, and, since the boiler’s parameters do not go beyond operational limits, the alarm and protection systems will not operate.

The relatively low weight and dimensions of the high-pressure boilers designed by the SKBK make it possible to install them in small shore boiler houses and electric power stations.

A small exhaust heat boiler is installed behind the high-pressure boiler to increase the efficiency of the boiler plant. It can generate the desired form of steam or heat water, depending on the boiler house’s requirements. The efficiency of this plant ranges from 93 to 96 percent.

With due regard to consumer requirements the SKBK has developed several boiler models: boilers fired by gas fuel or boilers fired by gas and residual fuel. The SKBK currently supplies three models: KVG3GM, KVG3M-GM (gas and residual fuel) and KVG2MG (for gas fuel).

The steam-generating capacity of boilers for stationary conditions is reduced to increase service life. The boilers are supplied fully assembled, can be shipped by rail or by sea and it takes 24 hours or less to arrange and install the boilers in the limited dimensions of standard medium capacity boiler houses.

The automatic control system employs microprocessors. The boilers are controlled from the central station by one operator. The control system, control fittings, turbo-supercharger, and exhaust heat boiler are supplied complete with the boilers.

The measured exhaust of nitric oxide is not in excess of 150 mg/nm3 when the boiler is fired by gas fuel and 250 mg/nm3 when fired by residual fuel.

In addition to high pressure automated boilers fired by gas and residual fuel, the SKBK is ready to supply:
– automated unattended boiler units with a steam-generating capacity of 6.3 and 16 t/h, a saturated steam pressure of 0.7 to 1.6 MPa fired by gas and residual fuel. The weight of the boilers is not more than 15 tons;
– exhaust-heat steam and hot-water boilers with a heating capacity of 0.1 to 25 MW;
– automated hot-water boiler unit KVGA 0.5 with a heating capacity of 0.5 Gcal/h, fired by gas fuel;
– automated boiler KGM 125-14-540, fired by gas-and-residual fuel, with a steam-generating capacity of 125 t/h, a superheated steam temperature of 5400 C, and a steam pressure of 13.8/9 MPa;

The SKBK is ready to design and supply any heat exchangers made of titanium, stainless or carbon steel, and hot-water boilers of any heating capacity.

The SKBK designs heating and machinery sections for boiler houses, supplies boilers, automatic control systems and boiler house equipment, performs supervisory installation, setups and commissions boilers for the customer, trains the customer’s personnel and performs boiler maintenance. All products are released to customers with the necessary licenses granted by the Russian Federation State Municipal Technical Inspection (Boiler Inspection) and the Russian Federation State Atomic Inspection agencies.

The low weight and small dimensions of high-pressure boilers for stationary propulsion machinery, good dynamic properties, and high reliability and maintainability make them very attractive for application at small and medium-size electric stations. The short installation, setup and activation time, no need for a heavy foundation provide economic advantages in terms of capital and working costs.

The space and cost savings over normal boilers of similar power have resulted in the SKBK receiving contracts with several large plants and power system departments in Russia and an oil refinery in Lithuania.

I think you’ve got the wrong end of the stick. As far as I recall, nobody has suggested that rebuilding Gorshkov would have been lower risk anywhere else. The argument is not over where it could have been done at lower risk than Sevmash, but the very silly claim (not by you) that rebuilding Gorshkov at Sevmash (& perhaps anywhere in Russia) was essentially risk-free.

Personally, I think that rebuilding Gorshkov was very high-risk wherever it was done, & that the lowest risk option was probably to have a carrier based on an enlarged Cavour (& very similar to the currently building INS Vikrant) built by Fincantieri, with Indians involved in design & construction, & the second of class built in India.

Well, I just got a bit tired of hearing Sevmash getting slammed. I figure they themselves didn’t quite realize what they were getting into.

Buque de Vigilancia Litoral (BVL)

These ships have been designed by Navantia for defence missions of the sea around Venezuela: protection of the fishing area, protection against smuggling and drug traffic, as well as the defence of the maritime traffic in general.

Main characteristics:
Length: 79.90 m.
Width: 11.50 m.
Depth: 7 m.
Displacment: 1,500 t.
Speed: 22 knots
Autonomy: 4,000 miles
Crew: 34 + 30
Armament: 1x 76mm Oto Melara compact naval gun, 1x 35mm Millennium gun

The POVZEE is bigger, with the same armament.

Lightly-armed coastguard-type patrol vessels, not fighting ships. They’re for fisheries & oil-rig protection, smuggler-chasing & the like.

And of course, to keep the Dutch out.
