2. Technology for Cleaner Air
Why Sea Water Scrubbing?
• Simple chemistry
• Proven application for land-based facilities
and as inert gas systems on petroleum & chemical
tankers
• Substantially minimizes harmful emissions
from diesel engines (SOx and particulate matter)
• Can be used in port or at sea

3. Scrubbed air exhaust
Krystallon Seawater Scrubber
How it Works - in Concept
Re-heat Section
Reheat Section
• Exhaust passes through a
Seawater Injectors
Sea Water Bath multi-sectioned scrubber.
Scrubber is designed to promote thorough
Seawater Scrubber Section mixing of gaseous engine emissions and

4. Shore Power Projects
EXISTING
Juneau Alaska, Seattle & Vancouver
PLANNED
San Francisco, Los Angeles, San Diego,
Long Beach
Criteria for a Successful Project
 Environmentally responsible source.
 Availability of an adequate supply of electricity at a reasonable
cost.
 Frequency of calls by cruise vessels equipped to connect to
Shore Power.
 Availability of the same dock and pier facility for these vessels for
every call.
 Adequate dock and uplands space for equipment.
 Willing partners including – utility, port and government agencies.
