A ship crosses
the Columbia
River.
|
The point where Oregon's powerful Columbia River
spills into the Pacific Ocean can become a navigational
nightmare for ship pilots, as huge ocean swells crash
into a sand bar at the entrance of the river. Add heavy
rain, high wind or low visibility to those rough
conditions, and you get a situation for which many
mariners are ill-equipped.
That's where the Columbia River Bar pilots come in.
They have the specialized knowledge to bring ships as
long as 1,200 feet through the risky waterway.
The danger
Up to a million cubic feet of water rushes from the
Columbia River into the Pacific Ocean every second.
"It's a very huge impact with the swells because of
the large current outbound and the force of the swells
coming inbound," explains Columbia River Bar pilot,
Capt. Michael Dillon.
Incoming ocean swells can double in size when they
enter the Columbia River. That's because they have to
cross the Columbia River Bar, a four-mile stretch of
sand that has built up at the river's mouth.
"Swells get upward to 23 to 24 feet, sometimes even
greater," explains Gary Lewen, a Columbia River Bar
pilot.
"The swells break as they hit the river. They lose
their backs and are no longer rounded. They become
almost like a shelf, like a cliff. And it becomes a
monster to handle sometimes," he said.
A safe passage
The Columbia River Bar pilots are considered
specialists who can utilize their unique knowledge of
the Oregon waterway that ships' captains may not have.
That's why they climb aboard ships to help them enter or
exit the river.

A breathtaking accident
The Columbia River Pilots have not lost a
single life in decades, but there have been close
calls. In 1994, Capt. Michael Dillon took a plunge
that nearly killed him.

"Current conditions
change by the hour, sands build up, there may be a shoal
area that's not there one day and is there the next day.
And the pilots are familiar with that on a day by day
basis," says Lewen.
"Once we get aboard the vessel, we effectively take
command of that vessel. It's kind of a hands-off
operation. The pilot doesn't touch anything other than
the radar and the radios," said Lewen. "The pilot's job
is not to steer, but to tell the helmsman how to steer
or what to steer," he added.
It is the responsibility of Columbia River Bar pilots
to keep freighters within the boundaries of a narrow
shipping channel. During rough conditions, just one
mistake could cause a ship to run aground. Or worse, a
ship could break in half and sink.
Treacherous weather

Severe
weather is not uncommon at the mouth of the Columbia
River, especially in the winter, when strong
low-pressure systems bring extreme weather. Incoming
storms can turn the enormous responsibility of Columbia
River Bar pilots into a heavy challenge.
"A large vessel, which is almost like the Empire
State building on its side, appears to be
indestructible. But, the ocean's an extremely powerful
force, and it can actually wipe things off the deck. It
knocks containers off, we've had ships come in with
containers just hanging off the side of it just barely
attached to the vessel anymore," explained Lewen.
In addition to churning ocean waters higher than
usual, storms can also produce blinding rain and fierce
winds that have blown pilots into the raging waters.
"We've had numerous occasions where the pilot boat
has actually come up with such force as to actually
break the pilot's legs," said Lewen.
River Bar pilots enter the oceangoing vessels from
smaller pilot boats that pull alongside the larger
ships. Then, the pilots climb rope ladders onto the
ships.
"We've had the pilot boat actually catch the pilot's
foot between the ship and the boat, and break the
pilot's foot."
But a broken foot is not the only concern during the
boarding process.
"When a pilot goes overboard, the first thing to
think about is to be hit by the propeller, and that can
of course, slice you in two. And that's the immediate
thing. Once you are out of that danger, then it's
drowning. Hypothermia and drowning if you are not found
immediately," said Captain Kell Aursland, Columbia River
Bar pilot.
