Excerpt from U.S. Coast Guard Proceedings of the Marine
Safety & Security Council magazine by Ms. Joan Lundstrom, chair, Harbor
Safety Committee of the San Francisco Bay Region.
The Harbor Safety Committee
of the SF Bay Region’s jurisdiction extends 100 miles from the San Francisco
Lighted Horn Buoy 12 miles offshore to the inland Ports of Sacramento and
Stockton.

The Harbor Safety Committee
(HSC) of the San Francisco Bay Region is continuing its collaboration with the
Coast Guard, the National Oceanic Atmospheric Administration (NOAA), the U.S.
Army Corps of Engineers, and local stakeholders to enhance navigational safety
and prevent maritime accidents and spills.
RESPONDING TO CHALLENGES
AIS Dock Identification System
In 2005, the HSC navigation
work group labored to develop a dock and berth numbering scheme based on local
codes used to indicate AIS locations. Working with the Coast Guard vessel
traffic service (VTS) staff, the stakeholders in the region numbered every
current and future dock in a logical and consistent manner.
Though there was some initial
reluctance to move away from the legacy dock and berth names, the VTS and
community became more comfortable using the new identification scheme, and it
has become the standard and the model for other regions.
Near-Miss in Dense Fog
Subsequently, during an HSC
meeting, a ferry captain reported a near-miss of two commuter ferries in dense
fog at the ferry building. The ferry operations work group analyzed and developed an
approach and maneuvering scheme for the congested ferry building approach and
departure area, as well as a routing protocol in the central Bay, to decrease
the risk of collision for commuter ferries.
With ferry routes charted,
other types of vessels, including recreational boats, can more easily predict
the locations of the fast ferries and steer clear.
Container Ship Struck Bay Bridge
In November 2007, a container
ship struck the Bay Bridge in dense fog. Within days of the spill, California Governor
Arnold Schwarzenegger directed the Office of Spill Prevention and Response to
investigate the causes and response to the allision. The office called upon the
harbor safety committee to analyze the navigational safety-related issues of
the governor’s directive and make appropriate recommendations regarding
prevention.
Loss of Propulsion Incidents from Mandated Low-Sulfur
Fuel
In 2009 another maritime
challenge arose when Coast Guard Sector San Francisco and the bar pilots
alerted the harbor safety committee of a dramatic increase in total loss of
propulsion of ships following implementation of the California Air Resources
Board (ARB) low-sulfur fuel switching requirement.
The HSC chair contacted the
ARB staff to meet with the maritime community to discuss the unintended
consequences of the regulation. As a result, the California Air Resources Board
agreed to actively promulgate safety exemption provisions to mariners, work
with the Coast Guard on outreach, and report monthly to the harbor safety
committee on waivers.
The Coast Guard and the HSC
continue to monitor propulsion failures in the San Francisco Bay region. While
the number of ships experiencing problems associated with fuel switching is
down, it is essential to determine where low-sulfur fuel results in a loss of
propulsion, determine the cause, and vigorously communicate lessons learned.
Every day commercial ships transit in and out of San Francisco Bay. |
