| Posted By: Tom Posted On: Jul 14, 2005 Views: 3744 | NEW CELEBRITY SHIP--DIESEL POWERED? DIESEL BELIEVER thinks RCL/CELEBRITY will be using diesel-electric propulsion in their new mega-liner. I would not believe these initial press reports. We shall see! All 8 COGES ships are performing exceptionally well, and earning more profits than the diesel ships. I think a COGES decision is very likely! |
| Posted By: DIESEL BELIEVER Posted On: Jul 14, 2005 Views: 3506 | New Celbrity ship Celebrity (which is a Royal Caribbean unit) has just signed a LOI with Meyer for a new "mega" ship. Meyer says "The ships will be able to accommodate 2,850 passengers in 1,425 cabins, and will be equipped with diesel engines and podded propulsion systems. The overall engine output will be 67,000 kW (91,400 hp)." Didn't see anything there about gas turbines or COGES Wonder if RCL or Clebrity are thinking about what it would cost to retrofit their existing COGES sships to diesel electric? They'd lose a few cabins, but... |
| Posted By: Tom Posted On: Jul 13, 2005 Views: 3418 | FOR DIESEL BELIEVER Just to set the record straight, there are currently 8 Cruise Liners utilizing COGES....4 ships at Royal Caribbean Int'l, and 4 ships at Celebrity. These ships do not require diesels for normal propulsion/ship service. |
| Posted By: Tom Posted On: Jul 13, 2005 Views: 3326 | Gas Turbine Containerships I wouldn't be surprised if the new 9,200 size, and larger, ships at SHI will utilize twin screws. Twin screws would be ideal for a very environmentally friendly, COMBINED GAS TUBINE-ELECTRIC AND STEAM (COGES) PROPULSION PLANT. The use of Bunker C Fuel will soon be prohibited....even on the high seas. |
| Posted By: DIESEL BELIEVER Posted On: Jul 13, 2005 Views: 3244 | Come off it, Tom With oil at $60 a barrel and gas turbine fuel prices through the roof, few cruise ships are likely actually running the gas turbine components of their diesel-gas turbine-electric power plants. The gas turbine may be fine for naval applications, but it still has to prove itself in commercial ships. The real answer is to tighten the permissible emissions levels from diesels and leave it to the diesel manufacturers research departments to further refine things like common rail injection. |
| Posted By: Tom Posted On: Jul 11, 2005 Views: 3155 | Containership PROPULSION As the Industry proceeds from very large containerships (VLCS) TO Ultra-Large ContainerShips (ULCS), naval architects and the shipyards are overlooking the real need for a change from DIESEL to GAS TURBINE propulsion. The huge, Low-Speed Diesels required for the new breed of ULCS, are the greatest, man-made, ENVIRONMENTAL AND CARCINOGENIC POLLUTERS ever PRODUCED for use at sea. ULCS design and operation result in very large and variable electric loads which are easily and efficiently satisfied by INTEGRATED AC-ELECTRIC DRIVE PROPULSION PLANTS using GAS TURBINES as the prime movers. DIESELS ARE NOT "FOREVER" IN CONTAINERSHIPS, JUST AS THEY WERE NOT FOREVER IN CRUISE SHIPS. Time to think CLEAN!....and efficient ULCS! |
