Full description

Hygienic drinking water on the high seas

They are the biggest cruise ships ever built in Germany. And they set new standards for holidays at sea: The four passenger ships of the Radiance class, built at the Meyer shipyard in Papenburg, are part of the Royal Caribbean International fleet, the world's largest cruise brand.

One of the floating luxury hotels is the "Serenade of the Seas," commissioned into service in 2003. The ship's "glassy" and futuristic design imbues it with a real aura of glamour. The glass frontage on the main restaurant provides a glorious view across the open sea. A further 16 bars, clubs and lounges appeal to every taste. The 2,500 passengers are looked after by a crew of 850. Royal Caribbean applies high standards of safety and comfort in line with its brand.

Luxurious travel thanks to ProPress

As one example, guests on-board the four-star cruise ship are supplied with nearly 400,000 gallons of drinking water a day. Those 160 gallons per passenger are not "consumed" in the many bars and restaurants, however, but in a sauna with pool and steam room, as well as by two more pools and three whirlpools on deck. The water is delivered by two evaporators and a reverse osmosis plant. It is distributed by the ProPress piping system.

A special feature of the ProPress system is Viega's "cold" press technology. Its advantages are particularly revealed in the tight space available on-board ship: The pressed connections are quickly fitted and provide safety thanks to Viega’s patented Smart Connect. In addition, no heat or sparking is involved in their installation as in the case of welded joints otherwise used for large pipe dimensions. This safety aspect is particularly vital in the event of repairs being needed while at sea.

Also the piping systems for operating air and heat use ProPress – making 93 miles of pipes in total. The time saved by cold pressing instead of welding or soldering was also useful in keeping to the tight deadlines in construction of the Serenade.
