CostaAtlantica gets perfect CDC score
Costa Cruises’ new flagship, the CostaAtlantica passed its semi-annual, unannounced sanitation inspection by the Centers for Disease Control and Prevention (CDC) with a perfect score of 100. The CostaAtlantica is one of only two vessels currently awarded a perfect score.

Since the early 1970’s, all cruise ships calling on U.S. ports are subject to these unannounced inspections as part of the CDC’s Vessel Sanitation Program. The inspections, conducted by U.S. Environmental Health Officers, focus on a checklist of 48 areas of sanitation including the handling, preparation and storage of food; plumbing, spa and pool facilities; onboard water supply; and equipment maintenance and personnel. Each ship is given a score based on a scale of 1 to 100, with an 86 or above being a passing score.

Up-to-date inspection reports are made available to the public at www2.cdc.gov/nceh/vsp/vspmain.asp.

Daewoo bags $1.1 billion in orders in one week
South Korea's Daewoo Shipbuilding and Engineering announced yesterday that, in the past week, it had succeeded in receiving orders for 10 vessels totaling $1.1 billion. They included 5 LNG carriers for Australian and Indian projects.

Daewoo had already received an LNG ship order in January from Belgian's Exmar. It has thus received orders for all the 6 LNG carriers contracted worldwide this year.

The new LNG carrier orders consist of three 138,000 cu.m membrane type LNG carriers (including two options) for the NWS(North West Shelf) Consortium involving by Chevron and other companies and two identical LNG carriers ordered by Mitsui O.S.K. Line which recently acquired the rights for transportation for the Petronet LNG Project in India.

Daewoo also won orders for what it describes as four "huge" containerships and one product carrier, but id not release further details,

In total, Daewoo has this year already won orders for 17 vessels worth $1.7 billion, about 70% of its sales target for the year.

What do you do with an unwanted nuclear sub?
Got any ideas of how to safely store an outmoded nuclear sub on land? If you do, go to http://www.lancs.ac.uk/users/csec/isolus/isolus.htm

The web page is part of the U.K.'s ISOLUS (Intermediate Storage Of Laid Up Submarines) project. It's a web-based survey running from April 2 to June 30 seeking public input on the problem of what to do with obsolete nuclear subs

The U.K. has 27 nuclear-powered submarines.

  • The MoD states that:

  • 16 are still in service
  • 9 have been defuelled and are being stored afloat - 6 at Rosyth (near Edinburgh) and 3 at Devonport (Plymout)
  • 1 (the Renown) is currently being defuelled at Rosyth
  • 1 (HMS Valiant) has been stored afloat at Devonport since 1994 waiting to be defuelled

So, the 11 UK nuclear-powered submarines that are no longer in service are currently stored afloat at dockyards at Rosyth and Devonport.
U.K. submarines taken out of service undergo a process called Defuel, De-equip and Lay-up Preparation (DDLP).

  • Defuel: the most highly radioactive material on board, the fuel, is removed and transported by train to Sellafield in Cumbria, where it is stored;
  • De-equip: equipment which is classified for security, or which can be reused or disposed of, is removed;
  • Lay-up Preparation: the submarine (which still contains the Reactor Compartment- is prepared for long-term storage afloat.

This has been done at Devonport and Rosyth. In future defuelling will only be carried out at Devonport. Devonport will also become the only UK site to refit nuclear-powered submarines that are in service.

By 2012 more submarines will have come out of service and there will no longer be enough practicable space at the existing berths to store them afloat at these dockyards. By 2040 all 27 of the current UK nuclear-powered submarines will have come out of service. Either more space for afloat storage will have to be provided somewhere, or an alternative means of storing the radioactive wastes will have to be developed.

Rolls-Royce establishes Naval marine organization to serve U.S.
Rolls-Royce has set up a dedicated U.S. marine organization to provide a complete range of products and services to the U.S. Navy, U.S. Coast Guard and naval defense contractors in the shipbuilding and ship maintenance business.

The Rolls-Royce facility in Walpole, MA, (formerly the Bird-Johnson Company) has been designated as the lead site for Rolls-Royce Naval Marine, Inc. in North America.

Rolls-Royce believes its naval business in the U.S. will continue to grow as customers increasingly look to companies that can provide equipment and systems or service packages from a single source.

Since the acquisition of Vickers plc in 1999, Rolls-Royce's marine capabilities have grown significantly. Its wide ranging portfolio includes gas turbines, propellers, podded propulsors, waterjets, stabilizers, steering gear and deck handling equipment.

Saul Lanyado, President - Marine for Rolls-Royce, said: "We are a global company serving 30 navies worldwide, but the ability to offer local support is crucial to our success. This new role for our Walpole facility is part of that strategy."’

He noted that the Walpole site has strong links with the U.S. Navy, having supplied every new U.S. Navy surface combatant ship class with controllable pitch propellers for the last 30 years, and had a strong tradition of customer partnering.’’

He cited the Smart Propulsor Product Model program, a contract with the U.S. Navy’s Naval Sea Systems Command, as an example of this partnering approach. Rolls-Royce Naval Marine is using its design and manufacturing experience to evaluate cost impacts of propulsor designs in a virtual environment.

The company’s early involvement in the development process will enable the U.S. Navy to select propulsors with the best performance at an affordable life-cycle cost.

Rolls-Royce is also applying the latest propeller technology to the LSD 41/49 class, which will provide a fuel efficiency improvement of over six per cent -- even before load management and maintenance savings are added.

Rolls-Royce software algorithms control propulsion systems on DDG-51, AOE-6 and LPD-17 vessels, and turbine overload protection systems operate on DD-963, DDG-993 and CG-47 classes.

Rolls-Royce supplies the U.S. Navy with gas turbine generators, including those for the current DDG-51 class. Almost 300 Model 501 gas turbines provide auxiliary power for all U.S. Navy destroyers and cruisers, with almost ten million hours of operating experience.

Other Rolls-Royce products now available to the U.S. Navy and U.S. Coast Guard include:

  • Water jets - the Kamewa range, from 90 kW to 50 MW, covers vessel types from pilot launches and patrol craft to the fastest commercial ferries and freighters; --
  • Pods - the commercially proven Mermaid) electric pod propulsion system, at 5-25 MW
  • Stabilizers and steering gear - Rolls-Royce fixed fin stabilizers are standard on FFG-7 class frigates. The company also offers Brown Brothers non-retractable stabilizers for naval vessels.
  • Steering gear covers all vessel types; and --
  • Underway Replenishment Systems - Rolls-Royce offers a range of automated, electrically-powered replenishment and refueling at sea systems consistent with the all-electric ship concept.

The AWJ-21, an innovative concept for applying proven waterjet technology in an underwater discharge configuration, is currently under development, in cooperation with the U.S. Navy’s Office of Naval Research.

Advantages claimed for the AWJ-21 include markedly improved cavitation performance, enhanced low speed maneuvering, higher efficiency, elimination of exposed shafting, struts and rudders, reduced ship draft and lower torque -- thus reducing overall machinery weight.

Presently, Rolls-Royce is carrying out hydrodynamic model tests. This scale model testing will be followed by a quarter-scale technology demonstrator program wherein a 1.5 MW AWJ-21 will be tested at sea in a craft capable of 30 knots fitted with electric drive. This will validate the powering, maneuvering, and cavitation characteristics and help predict the performance of larger configurations such as those required for surface combatant ships of the future.

Rolls-Royce also supports the Northrop Grumman led advanced cycle WR-21 marine gas turbine.

Northrop Grumman’s Marine Systems business, based in Sunnyvale, CA, is prime contractor for the WR-21 engine program, with overall responsibility for engineering and systems integration. Rolls-Royce has designed and developed the gas generator and power turbine. The WR-21 is currently being qualified for U.S. Navy applications in conjunction with the Royal Navy and French Navy at the DCN Indret facility, near Nantes, France.

Last month, Northrop Grumman and Rolls-Royce plc were awarded a contract worth approximately $120 million by prime contractor BAE SYSTEMS to supply 12 WR-21 marine gas turbine packages for the first six ships of a new twelve ship fleet of Type 45 air defense destroyers for the Royal Navy
