HARBOR SYSTEM MASTER PLAN - City and Borough of Sitka

Sitka Harbor System Master Plan
Condition Inventory
Findings
The electrical systems for this harbor were installed in
2007 as previously noted. All systems and system
components are essentially new and in good to excellent
condition. Given that this is a recent installation, it is
anticipated that the system was designed in compliance
with the current codes which have not changed with
respect to component ratings since installation. Thus,
the system capacity is sure to be adequate.
The noted exceptions involve the shore-tie pedestals.
The enclosures include hinged covers over the
receptacles and circuit breakers as previously noted. The hinges are weak and several are broken or
damaged.
The digital metering within the shore-tie pedestals is reportedly failing and difficult to repair and
calibrate. The CBS Electric Department is expressing frustration and a preference for conventional,
Form 1S, revenue meters. These utility grade meters provide a means for testing and calibration that is
already in affect at the department.
Also, the feeder cables from the service/distribution switchboard to the substations transition from the
gangways to the main float via support from a galvanized steel post. The loop from the gangway to the
post dips into the water during high tides, collecting marine growth and debris. This will reduce their
life expectancy. It appears that they can be fastened a little tighter to reduce their contact with the
water.
Excepting the above noted issues, the systems and components have a remaining service life of 25 to 30
years.
