will be powered mainly with its Wartsila diesel package, there will be times, according to Berends, when it will be necessary to employ Zuiderdam's GE gas turbine. Unlike recent new- builds, (such as Celebrity's new Millennium class introduced in 2000), the Vista Class vessels will not be pow- ered solely by the gas turbines.

Ciardiello) than operating on the turbines as the main source of power, the vessel will kick into gas turbine mode when travel- ing into environmentally sensitive ports, such as Juneau, Alaska. "At sea, we will employ three diesels," Berends said. "While the gas turbine is cost effective, it will be used in places such as Alaska so that we can properly comply with 'green ship' and environmental regula- tions." Another measure that Berends pointed out regarding the use of the diesel and gas turbines at the same time is the issue of an emergency situation — particular- ly in the vessel's engine room. Granted that if a fire were to occur in one of the vessel's engine rooms, the ship could function off its auxiliary power utilizing the diesel engines. The reason for this, according to Berends is merely one of "safety first," since diesels can kick into gear in just one minute — a gas turbine could take almost seven minutes to start up - therefore it would be a safety issue to use both at the same time. Moving up to the vessel's bridge room, February 2003 we had the opportunity to meet with the man at the head of Zuiderdam's controls - Capt. Jack Van Coevorden who has been working on HAL cruise vessels since 1972. Van Coevorden, who was born and raised in Indonesia, chose to be a Dutch national in 1951, and following his graduation from high school worked on cargo ships before moving over to the cruise sector. With all of the electronics equipment supplied by STN Atlas, the bridge also features a GPS by Leica, satellite com- munications by MTN and GMDSS via Sailor. Van Coevorden also points out that Zuiderdam, as well as all Holland America vessels, employ a separate "safety center" in the bridge area, con- sisting of fire control equipment, fire doors and the HI-Fog sprinkler system. In addition, smoke detectors can be heard in each individual stateroom with yellow flashing lights for the hearing impaired should a fire occur onboard - a first for the cruise industry. A "Waste" of Time A state-of-the-art wastewater system by Rochem and incinerator by Scanship for the removal of Zuiderdam's waste products was a bold move by HAL and Fincantieri, who traditionally employed ANCHORS CHAINS ^ORTELBOER the Zenon system onboard its ves sels. Environmental officer Willem Berends had nothing but positive feedback regarding the decision. "So far we are happy with the yard (Fincantieri) deciding to use the Rochem system," Berends said. "On this vessel, we employ a system that is of drinking water quality after the first stage of treat- ment." Despite this claim, however, HAL opted to treat the water a second time, via a reverse osmosis process, just to be 100 percent sure that the gray water is indeed of drinking water quali- ty. The filtration system designed for this process that treats both accommoda- tion gray water and laundry water, uti- lizes membrane separation with Rochem UF FM membrane module. According to Berends, "Rochem supplies low pres- sure reverse osmosis (LPRO) systems to properly treat the gray water and treated Tel.: +31 (0)10 429 2222 Fax: +31 (0)10 429 6459 info@wortelboer.nl www.wortelboer.nl black water to provide assur- ances that the treated water discharged." The Rochem FM Module sys- tem, which was designed for the purification of gray water according to IMO regulations, has a nominal total recovery of 85 percent, meaning that the supplied quantity of gray water is dis- persed into 15 percent waste water and 85 percent clean water.
