Grand Princess

The Grandest Of Them All

Grand Princess is the fifth ship to be built by Fincantieri for Princess Cruises. It has become the flagship of the Grand Class, which includes the two 77,000-gt sister- ships Sun Princess and Dawn Princess, delivered in 1995 and 1997 respectively.

Grand Princess can accommodate more than 2,600 passengers in 1,296 cabins, 700 of which have verandahs. In addition to suites, mini-suites and standard cabins, the ship has 28 wheelchair accessible cab- ins. It is presently the largest cruise ship operating in the world at a length of 935 ft. (285 m). The vessel has been classified by Lloyds Register of Shipping as well as

Rina of Italy, and is registered Liberian.

Two FP propellers are driven by a Siemens electric propulsion motor with 21 mW maximum output. The propulsion power and the ship's electrical power are provided by six Siemens generators, each producing 11,520 kW, driven by six GMT-Sulzer diesel engines. Grand Princess has achieved a maximum speed of 24 knots, but will cruise at a service speed of 22 knots. The vessel features all the exciting activities today's passengers expect, plus a virtual reality center, blue screen produc- tion studio, life-sized chess game, art gallery, and a computerized golf center.

Cruise Ship Repair: New Size, New Challenges

RENK gear systems - superior thanks to latest techno- logy and con- vincing quality - have proven their reliability for many decades when high performances and extreme technical requirements are demanded .This is particularly true for gear units which excel in maximum reliability when they are applied on high-speed vessels.

Their outstanding charac- teristics are: • Extremely light-weight due to compact design • Low-level noise generation thanks to optimal toothing • High availability due to high reliability

Moreover, RENK is renowned as a leading manufacturer of

Today's mega-sized cruise ships not only stretch the imaginations of ship designers, they tax the physical facilities and technical know-how of shipyards and equip- ment suppliers. Ship repair facili- ties, for either planned mainte- nance or emergency work, are another area of maritime forced to consider the dilemmas (and dol- lars) involved in servicing bigger ships. Rebecca Stewart, Newport

News Shipbuilding's head of ship repair, addressed the issue of larg- er ships at the recent ship repair conference hosted by the Maritime

Administration in Washington,

D.C. Stewart noted that today's cruise fleet features considerable amounts of high technology equip- ment and systems, including but not limited to advanced azipod propulsion systems, fiber optic communications and new materi- als, which are designed to make ships lighter and faster.

As shipowners increase demand for faster and better service — attempting to ensure their large investments' idle time is mini- mized — Stewart maintains that it is critical for a yard to have the physical facilities, scheduling flexi- bility, technical expertise and tools to accommodate all of these foreign built ships in order to compete.
