When Holland America Line's ms Zaandam sets sail from Vancouver, B.C., on Earth Day, April 22, it will be unlike any other cruise ship at sea, featuring new cutting edge emission reduction technology recently
installed during a two-week drydock. In cooperation with several United States
and Canadian government
and regulatory agencies, Holland America Line has launched a technology demonstration project
, designed to demonstrate the feasibility of using sea water to "scrub," or reduce, engine emissions on oceangoing vessels.
The sea water scrubber system, developed by Krystallon
, a subsidiary of
, uses the natural chemistry of seawater to remove virtually all sulfur oxide (SOx) as well as significantly reduce particulate matter emissions.
The sea water is then treated to remove harmful components while the calcium carbonate (CaCO3) in seawater renders the sulfur oxides harmless by conversions to sulfates and neutral salts.
The price tag tops more than $1.5 million and includes assistance of
$300,000 from an Environmental Protection Agency
Collaborative grant and a $100,000 contribution from Puget Sound
Agency. Additional support for the project comes from the Port of Seattle,
the Port of Vancouver, Environment Canada, British Columbia Ministry
Environment and the B. C. Clean Air Research Fund, as well as Krystallon.
Each government agency has representatives serving on a technical advisory
committee that oversees the development of this project.
Holland America Line demonstrates its commitment to responsible
environmental practices through a comprehensive fleetwide program that
emphasizes compliance with all international environmental guidelines,
waste reduction and recycling, and a history of embracing new environmental
technologies such as state-of-the-art water treatment systems, shore power
while ships are in port, and an internationally-recognized whale strike
In June 2006, Holland America Line's Environmental Management System
received the international ISO 14001 certification, demonstrating that the
company conforms to higher standards than what is just required by the
letter of the law. Holland America Line's ships currently meet or exceed
all provisions of the international regulations governing the environmental
management of marine operations. An environmental officer serves on each
ship to oversee shipboard compliance and procedures.
