ITEM #1 Call to Order
Chris called the meeting to order. There were 42 members in attendance.
Chris introduced Dr. David
Rezachek, of HSWAC (Hawaii Sea Water Air Conditioning), LLC.
What is seawater Air
Conditioning? Cold sea water
is pumped up from a depth of 1,600 to 3,000 feet of depth.
The cold water is around 42 to 45 degrees Fahrenheit.
It goes through a heat exchange where it cools a closed circuit
re-circulating fresh water system.
This is what cools the rooms.
Because there is a slight warming of the seawater it is chilled
slightly before being returning to sea.
The sea water is then returned to the ocean where it is rapidly mixed
with the sea water.
Cold seawater is free, accessible and renewable
SWAC provides reduced and stable air conditioning costs.
Has a number of environmental benefits.
It is not a new technology.
It is used in many areas around the world including
The pipes are made out of HDPE.
In a 63 inch pipe the wall thickness is about 3” thick the pipes are
heat fused together. These
“welds” are as strong as the parent material.
Concrete anchors hold the pipe to the bottom.
Under water life expectancy could be as much as 100 years.
Installation will be from the
shore using directional horizontal drilling to a depth of about 30 to 40 feet
deep at a region outside of the near shore coral reef area.
This may be a distance of about ½ mile offshore.
Then the cement anchors will hold the pipeline just above the ocean
All the pipes will be either
under ground or under water. The
only visible structure will be the pumping station.
This will be housed in a parking structure.
Various buildings will be connected to the system via pipes.
They are currently completing an archeological survey of the
distribution route. These
distribution pipes will be about 3 to 3.5 feet of depth.
The supply pipe will be insulated.
These pipes are around 10 inches in diameter.
This system is estimated to
say about 145,000 barrels of oil per year.
It should also say about 265,000 gallons of potable water per year
which used in energy production process cooling towers.
These evaporate potable water to cool production processes.
This will be a two day savings of potable water for all of
This system will also help
City and State governments to meet goals and mandates for energy efficiency
improvements. The 25,000 ton
HSWAC project will eliminate the need for up to 17 megawatts of new
generation. Currently new
generation plants are running behind demand.
This will ease the development crunch.
It is also expected that electrical rates are going to continue to
climb, perhaps as much as double over the life expectancy of the project.
In a SWAC system about 80 percent of their costs are fixed operational
costs that are predictable. Oil
based cooling systems are cheaper to install but their long term operating
costs are tied to the price of oil and far more expensive and less
Secondary benefits include the
potential of using the return water as process cooling water for the downtown
power plant for example.
$80,000,000 in bonds is being
requested from the State. In
all, the initial capital installation costs are estimated to be about
bonds have been secured and customers are being asked to commit to a 20 year
contract to guarantee the bonds. The
buildings internal infrastructure will require very little change.
Some connection capitalization may be required but HECO is providing a
$200 per water ton rebate to help offset these capitalization costs.
ITEM #3 Joe Curtis -
Joe runs the training center
at Barber’s Point for the Seafarer’s
They have air conditioned
class rooms available, one for 36 and another for 50 participants.
This is an extension of the main training center located in
They have a burn building that
simulates and engine room fire with the ability to demonstrate a roll over.
They can also simulate Bridge and Galley fires.
All of their water is recycled.
They also have a helicopter fire simulation prop.
They have a 50,000 gallon pool in which they conduct “Life Raft”
classes and Survival Suit training.
They can also conduct “Damage Control” training to teach techniques
for plugging holes in the hull.
As long as the cruise ship
They are licensed to teach as
many as 100 people at a time.
They have recently conducted some training for NOAA.
ITEM #4 Ward
Graessle, Offshore Marine Surveyors - Casitas
Ward Graessle served as the
owner’s agent during the salvage operation, and showed photos of the
grounding and salvage operation.
The 145 ft. Casitas ran
aground on July 2nd, on
Approximately 30,000 gallons
were removed fairly early on by the USCG Cutter Walnut.
Also, there was about 10,000 gallons of gasoline in drums stored in a
container on the deck.
They were right on the edge of
the reef. On the
inboard side the depth varied between 1 to 2 feet.
On the outboard side it was about 12 feet and the depth dropped off
The only pollution was from
the internal diesel day tank that leaked into the engine room.
This tank was emptied by the crew to attain source control.
They hydrocarbons on board were successfully removed during the
Once oil was removed from the
vessel sea water was back filled with sea water to ballast the vessel down to
seat it firmly on the reef. This
helps to minimize reef damage.
American Marine was hired to
conduct the salvage. They
brought in a barge that was ideally configured to conduct pulling/salvage
operations. This barge was
on its way back to
Chris Woolaway announced as a
side note, that the work that the Casitas was undertaking derelict net
recovery. This was
that last year for funding for this project.
NOAA has contracted with another vessel to continue this work.
In addition, the USCG Cutters Kukui and Walnut will complete their
portion of the work.
ITEM #5 USCG Concerns
Captain Brown reported that he had no announcements.
of DBOR, announced that DLNR received funding for the Kahului Boat ramp work.
This was to be a triple wide boat ramp.
When they opened the bids last year they discovered they were short of
efforts at the Legislature were successful in getting the additional funds to
complete this project.
from State Harbors announced that funding has been approved to construct a
boat ramp, docks and toilet facilities at the
reminded everyone that the “Get the Drift and Bag It” clean up effort will
happen on September 17th.
Robin Bond thanked everyone
for their presentations and encouraged the group to think of possible topics for
