The
year 1999 was a memorable one weather-wise for the southeastern United
States. Several major hurricanes passed over or near the region, leaving
flooding and devastation in their wake.
When they strike,
hurricanes can cause widespread hardship and misery. They also can
disrupt the operations of ports, as well as the water, rail, and road
connections that lead to them. These disruptions affect the livelihood
of communities throughout the region, so it is important that the
duration of any disruption be kept as short as possible. This is why the
U.S. Coast Guard works quickly—in cooperation with port authorities,
tenants, and users—to reopen ports to commercial traffic in the
aftermath of a storm.
By law, Coast Guard
safety officials are the final arbiters of whether ports remain open, or
close—and, if the latter, when they reopen for business. They must
balance the economic demands of commerce with the demands of marine
safety and environmental protection. Two 1999 examples from East Coast
ports—Hampton Roads, Va., and Wilmington, N.C.—demonstrate how Coast
Guard units accomplish these critical tasks.
The Coast Guard and
Ports
Responsibility for the
safety, efficiency, and environmental soundness of marine operations in
U.S. waters and ports lies mainly with the Coast Guard. At the heart of
the Coast Guard’s preventive safety efforts are 46 Marine Safety
Offices (MSOs) located throughout the United States. MSO personnel,
supported by a cadre of marine inspectors, conduct a host of safety
patrols, foreign vessel boardings, U.S. vessel inspections, and marine
facility inspections. The commanding officers of the MSOs serve as
Captains of the Port (COTPs), as the Officers in Charge of Marine
Inspection (OCMIs), and as Federal On-Scene Coordinators (FOSCs) during
emergencies.
In practice, Coast
Guard district commanders usually have the final say on port operations
in the face of approaching storms. The COTPs execute the orders handed
down from the district level—but they have the authority to order
levels of readiness higher than those that the district directs. The
COTPs also work with port users, tenants, and administrators in
implementing the details involved in port readiness.
The Marine Safety
Offices in Hampton Roads and Wilmington fall under the control of the
Fifth Coast Guard District, which is commanded by Vice Adm. John E.
Shkor. The COTPs for the two ports, Capt. John Schrinner in Hampton
Roads and Capt. John Williams in Wilmington, are quite familiar with the
demands and challenges of hurricane preparation and recovery, as their
commands lie in an area that is a common pathway for these tropical
cyclones. But, as Williams explained in an autumn 1999 interview,
"Every hurricane has a different character, and we are faced with a
unique set of challenges every time we deal with one of these
storms."
Ports in the Bullseye
The locations of the
ports of Hampton Roads and Wilmington make them important gateways for
national and regional trade. According to the Department of
Transportation’s 1999 report, An Assessment of the U.S. Marine
Transportation System, Hampton Roads had the second highest volume of
international trade of any U.S. port. Its facilities handle more than
ten million tons of containerized cargo each year, plus large amounts of
grain, fertilizer, and sugar. Hampton Roads also owns the nation’s
largest coal exporting facilities.
The port of Wilmington
has a much more regional economic impact. It, too, handles container
traffic, but bulk cargo traffic such as paper and forest products
comprise a large part of the commerce that passes through the port.
Nevertheless, Wilmington is an important node in the trade flows between
North Carolina’s burgeoning hinterland cities and industries and the
rest of the world.
The same locations that
make them key trade conduits also put the two ports in harm’s way when
truly dangerous weather roars in. This is especially true of Wilmington,
which has been struck by five hurricanes in the last four years. Hampton
Roads, farther north than Wilmington, has been far more fortunate—Virginia’s
relatively short coast has taken only four direct hits from hurricanes
since 1899. Still, this has not spared the port from being lashed by
hurricane-force winds, storm surges, and torrential rains from storms
that first came ashore further south.
In 1999, the most
destructive hurricane to hit the southeastern Atlantic region was
Hurricane Floyd. Although it weakened before reaching the United States,
Floyd still packed sustained winds of 99 miles per hour when it made
landfall near Cape Fear south of Wilmington on 16 September. After
flooding large swaths of the Tarheel State, Floyd plowed inland over
Virginia and Maryland and points north, weakening as it went. It left 42
people dead in the United States, along with large numbers of families
and individuals homeless or displaced. It closed highways and flooded
rail lines throughout the Southeast and mid-Atlantic regions. And it
forced the ports of Wilmington and Hampton Roads to cease operations.
However, thanks to the
fast and efficient work of the U.S. Coast Guard and its partners, the
closures did not last long—Wilmington was open for business
approximately 48 hours after the storm’s passage; Hampton Roads fared
even better, reopening in six hours.
Preparation for
Hurricanes
The basic hurricane
preparation procedures that the two MSOs follow are similar. At the
start of each hurricane season, which normally runs from June to
November, the Coast Guard sets internal Hurricane Condition 5, the
lowest level of readiness (the highest being Condition 1). The setting
of Condition 5 is a signal for Coast Guard units in the area to
refamiliarize themselves with the details of the port’s hurricane
contingency plan. Meetings also are held with port officials, shipping
line representatives, and harbor pilots to reacquaint them with the plan’s
requirements as well.
When a hurricane
actually approaches the East Coast, upgrades in the Coast Guard’s
internal hurricane conditions—and in the publicly announced Maritime
Hurricane Condition—trigger specific sets of actions by both the Coast
Guard and private industry. These actions vary slightly from port to
port. On the Coast Guard side, district and MSO personnel begin to keep
a detailed watch on the storm’s movements. If storm path projections
indicate that a strike is likely in the port area, the local COTP sets
Condition Whiskey.
The MSO uses every
means at his disposal—including telephone calls, faxes, e-mails, and
press releases—to notify all concerned of the change, and continues to
do so each time the Maritime Hurricane Condition changes. Vessels in the
area are notified directly via a Broadcast Notice to Mariners.
With the hurricane
procedures in effect, the MSO initiates meetings with port authorities
and industry. The participants identify ships that might have to ride
out the storm in port, and those that will be asked to leave and seek
safety on the open sea. "The participation of harbor pilots,"
Schrinner noted in an interview, "is a key part of this
process."
Meanwhile, MSO
personnel also step up their harbor patrols and inspections to determine
whether preparations by ships, facilities, and marinas are adequate.
The pace and gravity of
storm preparations increase when hurricane-force winds are estimated to
be only 24 hours away and Maritime Hurricane Condition Yankee is set.
The COTPs restrict inbound commercial traffic and make detailed
decisions as to which, if any, vessels remaining in the port will be
allowed to stay.
Waterfront facilities
must apply for COTP permission to have commercial vessels or barges of
greater than 200 gross tons remain moored at the facility during the
storm. The MSOs establish Crisis Action Centers to deal with any or all
of several types of emergencies that will invariably begin to develop
with the storm’s approach. MSO Hampton Roads also sends liaison
officers to the Virginia Pilot Association station to help monitor
vessel status.
No True Haven
Condition Zulu is set
when the hurricane’s fiercest winds are calculated to be 12 hours
away. At this point the COTPs prohibit the movement of virtually all
commercial traffic. The transfers of dangerous bulk liquid cargoes and
bunker fuels are suspended, as is any lightering of liquids from larger
to smaller vessels. Waterfront facilities are required to secure their
equipment against spills and other hazards. The MSOs monitor all of
these last-minute preparations.
Although Hampton Roads
and Wilmington follow similar procedures, location and geography drive
some differences between their preparations. In Wilmington’s case, all
ships not permitted to remain in port must leave Wilmington at least 15
hours prior to the predicted onset of gale-force winds, giving these
vessels time to proceed down the Cape Fear River, clear Frying Pan
Shoals at the river’s mouth, and head to safety.
This is a recent
change. Prior to Floyd, ships in Wilmington were required to depart the
port 24 hours in advance of hurricane-force winds likely to hit the
area. The rule was changed in Floyd’s aftermath because several
vessels had been "trapped" in Wilmington by the storm’s
approach.
In Hampton Roads, the
COTP can assign hurricane anchorages to the ships that were unable to
make open sea safely before the onset of hurricane conditions. MSO
personnel work with the Virginia Pilot Association to identify anchorage
areas that provide a buffer between other anchored ships and the
shoreline. From a safety standpoint, however, the Coast Guard prefers
that ships evade the hurricane by putting to sea, because no harbor in
the area provides a true haven during a hurricane.
The exodus to the
Atlantic by ships evading oncoming hurricanes does not mean commercial
vessels only. In Hampton Roads, the port evacuation also includes
approximately 80 warships and auxiliary ships of the Navy’s Second
Fleet. Larger Coast Guard cutters also leave port. (Conversely, many
Coast Guard small boats and craft from outlying stations seek shelter in
either Hampton Roads or Wilmington during hurricanes.)
Riding Out the Storm
Moving ships out to sea
is perhaps the most important safety precaution that ports can take in
advance of a hurricane. But it is not always possible to get every large
vessel out of danger. For instance, with Floyd approaching Wilmington,
Williams placed three ships under a COTP order to leave port. However,
as their departure preparations dragged on, their masters had a
collective change of heart about heading south down the Cape Fear River.
"After a while,
they all said they couldn’t get underway, stating that it was no
longer safe," Williams recounted, "and the [harbor] pilots
supported them." The long trip from Wilmington down the Cape Fear
River and around Frying Pan Shoals would have put the ships squarely in
Floyd’s path. After a quick analysis of the storm’s movement,
Williams and his staff agreed to allow the vessels to remain in
Wilmington. The ships managed to ride Floyd out safely, but the incident
caused the change in policy for port departures mentioned earlier.
In general, any ship
remaining in port in a storm must double up its lines, rig anchors for
quick release, shift ballast (if necessary) for maximum stability, and
have all of its pumps and manifolds on line. The Coast Guard also
coordinates with local tugboat companies to ensure emergency-response
services are available in case the advance preparations are not enough
to keep vessels at their moorings during the storm.
The value of these
types of preparations was proven as the still-potent Floyd passed over
Hampton Roads. The 718-foot-long Chinese heavy-lift merchant vessel Zhen
Hua 4—loaded down with two massive, 219-foot-high cranes—broke loose
from its moorings at Norfolk International Terminal and was blown onto
an adjacent pier. Reacting quickly, the Coast Guard requested assistance
from four tugs, which converged on the wayward vessel along with an MSO
Marine Safety Team. After some careful maneuvering, Zhen Hua 4 was again
moored securely at the terminal. Damage to the ship, its cargo, and the
pier was minimal.
Elsewhere, nine vessels
of the Navy’s Ready Reserve Force moored at the mouth of the James
River north of Norfolk dragged their anchors and drifted westward. MSO
Hampton Roads deployed another team to help coordinate and monitor the
vessels’ eventual return to their berths. Fortunately, the ships did
not run aground or drift into shipping channels, and local tugs were
able to control their movements.
Aftermath of the Storm
After a hurricane has
swept over and through a port, the Coast Guard’s first priority is
damage assessment, including any damage done to aids to navigation (ATONs).
The assessment is used to determine the condition of shipping channels,
the presence of breakaway ships or barges, and any damage to port
facilities that could cause a safety or pollution hazard.
Again, the port’s
geography often determines many of the specific actions that MSO
personnel take. According to Jerry Crooks, chief investigation officer
with MSO Hampton Roads, one of the most expeditious means of finding out
roadstead conditions in that port is to call state highway personnel
stationed on the Chesapeake Bay Bridge Tunnel and/or other area bridges
and simply ask them for visual observations.
The MSO also receives
initial readings on the condition of channel navigation aids from a
Coast Guardsman riding a harbor pilot boat from Cape Henry at the mouth
of the Chesapeake to the piers at Portsmouth. Traffic-monitoring
personnel in a pilot tower at Cape Henry also carry out visual and radar
checks on buoys in Thimble Shoals channel. "We use these … checks
to establish an initial ‘comfort zone,’" Crooks said.
These actions usually
are accompanied by aerial and land-based inspections. A Coast Guard
helicopter will fly over the main channels of the port, for example,
looking for missing buoys, vessels adrift, the presence of wrecks or
debris in the channel, and thin, colored sheens on the water (which
indicate the possibility of oil or chemical leaks).
Meanwhile, teams from
the MSO also fan out ashore in four-wheel-drive vehicles to check the
integrity and safety of port facilities, as well as those of the
numerous chemical plants and refineries along Hampton Roads’
waterways.
In Hampton Roads,
District Five will assign buoy survey duties to cutters returning from
sea. As they proceed to their piers, the cutters use their Global
Positioning Satellite (GPS) systems and other methods to ensure that the
buoys are still in their charted positions. Wilmington does not have
cutters at its disposal for similar ATON duties. So, like its commercial
brethren, the Wilmington-based cutter Diligence cannot enter the
potentially treacherous Cape Fear River channel until aerial and surface
surveys—augmented by the observations of river pilots—ensure that
navigational aids are in place and the channel is unobstructed.
The Lessons-Learned
Phase
Obstructions are always
a key concern in the post-storm surveys. The initial surveys and other
assessment efforts identify any barges or other watercraft that have
grounded, been blown into the channel, or sunk and become hazards to
other ships. The Coast Guard can rely upon contract tugs in an
emergency, but for the most part the owners of wayward vessels are held
responsible for corralling any of their craft that have broken loose,
and for salvaging those that may have sunk.
Submerged buoys also
can be major hazards to navigation. When a buoy is not where it should
be the MSO will coordinate with the Army Corps of Engineers—the agency
responsible for keeping the channel open—or with the National Oceanic
and Atmospheric Administration to search for the buoy with side-scan
sonar. In all such situations, the Coast Guard notifies mariners of the
problem and marks the hazards to ensure they cause no further problems.
Once the MSOs are
convinced that local waters are again safe for commercial traffic, the
port will be reopened. In Hampton Roads, the first people notified are
the harbor pilots, because they decide how to sort the long queue of
ships waiting to enter port. Anxious port-authority personnel and
shipping agents also receive quick notification, usually by fax and
phone call. Ships’ crews get the word directly from the Coast Guard
via marine broadcast. Wilmington follows similar reopening procedures.
Declaring a port open,
however, does not mean that everything is back to normal. For the MSOs,
the process of evaluating the lessons learned during the hurricane is
just beginning. An important part of the evaluation process, Schrinner
points out, is "meeting with the port players, who give us very
valuable feedback as we refine our hurricane preparedness
procedures."
Meanwhile, other Coast
Guard units are engaged in restoring the damaged, destroyed, or
displaced aids to navigation. Coast Guard Aid to Navigation Teams (ANTs),
operating from small boats, service small buoys, lights, and fixed
structures. To reset a larger buoy, however, which can weigh in at more
than four tons, requires a buoy tender. This and other restoration work
can continue for a month or more, depending upon the hurricane’s
severity.
Just the Beginning?
"This is something
we are going to have to get used to," Williams conceded when
discussing Wilmington’s five hurricane strikes in four years. Indeed,
some forecasters see evidence that the next few years may resemble the
1930s and 1940s, when huge storms regularly made landfall on U.S.
coasts. If these fears are realized, Wilmington—and maybe even
relatively sheltered Hampton Roads—will likely feel the brunt of a
number of other heavy storms in the years ahead.
When a hurricane
"decides" to hammer the U.S. coast, there is nothing anyone
can do to prevent it. For that reason alone, it seems evident, having an
agency available that can coordinate port preparation for and recovery
from these life-threatening storms is essential for safety,
environmental, and economic reasons.
Today, and for a very
long time to come, in all probability, the Coast Guard will be that
agency, serving as perhaps the most essential public or private-sector
organization available to help ports weather the worst that Mother
Nature can throw at them.
