Late this afternoon the Coast Guard released the final report on the sinking of the Fishing Vessel Alaska Ranger that sank in the frigid waters north of Dutch Harbor, Alaska on 23 March 2008. Though “only” five of the 47 people on board were lost the fact remains that any loss of life is tragic. The full report can be found here (9) in all its nearly 200 page glory… (or read embedded version below). I’ve also included today’s press release on the matter below.
On the subject of the Alaska Ranger I’d like to point out that author Kalee Thompson also release a book covering the heroics of rescuing the 42 that were alive. The book, Deadliest Sea: The Untold Story Behind the Greatest Rescue in Coast Guard History, is a must read as the rescues itself, as touted by Thompson’s book title, is, perhaps, the greatest rescue in Coast Guard history.
Here is the report; press release is below it.
12 January 2011 Press Release:
WASHINGTON — The Coast Guard released Wednesday 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.
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 Ranger’s 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.
The 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.
The report of investigation details the findings of the Coast Guard’s marine board of investigation as well as recommendations for enhancing safety for fishing vessels.
The 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.
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.
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.
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 ACSA requirements.
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.
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.
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.
