WASHINGTON, D.C. The Coast Guard on Wednesday released its final
report of the investigation into the March 23, 2008, sinking of the
fish-processing vessel Alaska Ranger and the subsequent loss of
five of the 47 people aboard the ship.
“margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica;”>The
Alaska Ranger sank approximately 130 miles west of Dutch Harbor,
Alaska. Of the 47 people aboard, 42 were rescued, four deceased
crewmembers were recovered and one remains missing and is presumed
dead. The Coast Guard rescued 20 of the Alaska Rangers crew
through multiple hoists conducted by HH-60 and HH-65 helicopters,
with survivors being transported to and cared for aboard the Coast
Guard Cutter Munro. The fishing vessel Alaska Warrior rescued 22
survivors from two liferafts and recovered three deceased crew
members from the frigid water. The fourth deceased crewmember was
recovered by the Coast Guard.

Alaska Ranger was a 189-foot, 1,577 gross ton, fish-processing
vessel in the Bering Sea/Aleutian Island federal groundfish trawl
fisheries. The vessel was owned by the Fishing Company of
Alaska.

report of investigation details the findings of the Coast Guards
marine board of investigation as well as recommendations for
enhancing safety for fishing vessels.

Board determined that the cause of the sinking was flooding that
likely started in the rudder room, but rapidly progressed to the
engine room and other spaces due to a lack of watertight
integrity.
“margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica;”>While
the exact source of the uncontrolled flooding remains unknown, a
thorough analysis of the facts indicates the most likely source was
related to the vessel’s poor material condition and may have been
related to the Kort nozzle struts. The struts support the nozzles
shrouding the propellers at the stern of the vessel and are
believed to have experienced excessive stresses where they were
attached to the vessel’s hull.
“margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica;”>The
Board concluded that the Fishing Company of Alaska failed to
properly maintain the structural condition of the Alaska Ranger.
Evidence of extensive and repeated fracturing of the nozzle struts
and structural failures in the aft ballast tanks and potable water
tanks went unaddressed.
“margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica;”>At the
time of the casualty, the Fishing Company of Alaska had enrolled
the Alaska Ranger into the Coast Guard’s Alternate Compliance
Safety Agreement Program, commonly referred to as ACSA. However,
ACSA had not yet been effectively implemented, and the Alaska
Ranger, with several outstanding deficiencies, was not in
compliance with all ACSArequirements.
“margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica;”>Based on
its findings, the Board made 37 recommendations that address the
lack of comprehensive safety regulations for fishing vessels,
facilitate the consistent application of existing regulations and
correct shortcomings in the ACSA program that existed at the time
of the casualty.

Recommendations were also made to ensure crew members have properly
sized immersion suits, and to clarify and enforce requirements for
licensed crewmembers.
“margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica;”>Related
to the investigation, the Coast Guard published two marine safety
alerts. Alert 1-08, published on May 9, 2009, urged owners and
operators to take immediate action to ensure the watertight
integrity of their vessels. Alert 3-08, published July 2, 2008,
emphasized the need for vessel owners, operators and masters with
controllable pitch propellers to understand the design and
operation of their system.
“margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica;”>The
Coast Guard’s 2010 Authorization Act, signed in October 2010, set
new requirements for commercial fishing vessels that, when
implemented, are expected to enhance crew and vessel safety.
Included in the Act are provisions for mandatory safety
examinations for vessels operating beyond three miles at sea, as
well as construction standards for new vessels greater than 50 feet
in length. Additional standards will also be imposed for vessels
greater than 79 feet in length.

According to the National Institute for Occupational Safety and
Health, from 1994 to 2004, 641 commercial fishermen died while
fishing in the United States. Vessel sinkings resulted in more than
half of all fatalities. While work-related fatalities for
commercial fishermen in Alaska are still very high, they have
decreased by 42 percent since the early 1990s. This success is due,
in part, to the Coast Guard implementing new safety requirements in
the early 1990s.
