Insufficient Training, Inadequate Bridge Operating Procedures, Lack of Operational Oversight Led to Fatal Ship Collision. The National Transportation Safety Board said Monday that the Aug. 21, 2017, collision between the USS John S McCain and the tanker Alnic MC was caused by insufficient training, inadequate bridge operating procedures and a lack of operational oversight.Ten sailors aboard the John S McCain died in the accident and 48 were injured when the ships collided in the Middle Channel passage of the Singapore Strait Traffic Separation Scheme.

Ship Mooring Chocks – New International Standard

A new ASTM International standard covers the principal dimensions and materials of closed chocks, used for mooring, for installation on ships. The new standard, ASTM F2935, Specification for Chocks, Ship Mooring, Cast Steel, has been developed by Subcommittee F25.01 on Structures, part of ASTM International Committee F25 on Ships and Marine Technology. Chocks are mounted directly on the deck, on the foundation or in a bulwark of a ship. Chao H. Lin, Office of Safety, Maritime Administration, U.S. Department of Transportation, and F25.01 chairman, notes that chocks are an essential apparatus for tying a vessel to a dock or pier. Shipboard hardware designers and manufacturers…

ASTM Seminar on SOLAS and Navy Vessels

The ASTM International seminar, Fire Testing for SOLAS and Navy Vessels: New Test Procedures and Material Approval Process, will be held Dec. 7 at the Tampa Marriott Waterside in Tampa. Sponsored by ASTM Committee F25 on Ships and Marine Technology, the seminar will be held in conjunction with the committee’s December standards development meetings. Major revisions to the International Code for the Application of Fire Test Procedures (FTP Code) were approved by the International Maritime Organization in December 2010. The revisions become effective on July 1, 2012, and all approval tests after June 30, 2013, must be to the revised procedures.

Proposed ASTM Standard to Cover Use of Doublers in Ship Repair

Many ship owners and operators repair ship structures with temporary steel patches known as doublers. The U.S. Coast Guard and Navy, as well as other maritime authorities, usually allow such patches until the ship’s next inspection period, which can be as long as three to five years from the date of repair. Despite this situation, there is not currently a standard for repairing steel hull ships with doublers.Subcommittee F25.01 on Structures is now working on a proposed new standard that will cover doublers: ASTM WK30649, Guide for Steel Ship Structure Repair Doubler Plate Design. The subcommittee is part of ASTM International Committee F25 on Ships and Marine Technology.

Feature: New Aluminum Marine Alloy Specification Developed

The Aluminum Association, Inc. The recent publication of the new specification - ASTM B928 High Magnesium Aluminum-Alloy Sheet & Plate for Marine Service - is the culmination of a cooperative effort between numerous parties involved in the marine industry including aluminum producers, boat builders, the Coast Guard and marine classification societies. The combined work of these groups will help to address the communication gap between marine end users and distributors of aluminum that became apparent in late 2001/early 2002 in the Pacific Northwest. As has been reported in various marine industry publications, the performance of some…

Bunkering Testing Breakthrough

Octel Petroleum Specialties, the UK fuel additive manufacturer, has made a significant breakthrough in the science of predicting the stability of heavy fuel oils. The development could lead to greater efficiency in critical applications such as estimating the oil quality before bunkering and evaluating the benefit of additives for upgrading Bunker “C” fuel oils. Bunker "C" oil is currently produced by blending the oil remaining after the refining process with lighter oil. The main destination for Bunker “C” is ships using diesel engines for propulsion. Traditionally, predicting the stability of Bunker "C" is fraught with difficulty, largely because stability is ill defined and also because previous methods have been somewhat subjective. This, however, is about to change.

Brandemarte Receives Wyman Memorial Award

Albert V. Brandemarte has received the L. L. Wyman Memorial Award for 2002 from American Society for Testing and Materials (ASTM) International. The award is given annually in recognition of meritorious contributions to standardization in the field of metallography through the work of ASTM Committee E04. Brandemarte serves as chief of metallography for the Naval Surface Warfare Center Carderock Division's Metals Department in Bethesda. He has been a member of the ASTM committee E04 for 14 years and served as committee chairman from 1998 to 2002. Through his work on the committee, Al became a nationally recognized expert in metallography, a critical tool in most Navy ship failure analyses. The award is named for L. L. Wyman, chairman of the Metallography Committee from 1938 through 1966.

Aluminum Gone "Bad"

There has been a lot of discussion in the marine industry over the past year with regard to "bad" aluminum. To briefly recap, a number of boat builders purchased aluminum from a supplier that met the requirements of ASTM 5083 H321. This alloy is accepted by both Lloyds Register (Lloyds) and Det Norske Veritas (DNV) for building aluminum vessels. After the aluminum was used to construct some vessels, the operators began to observe surface pitting corrosion. Upon investigation, it was discovered that the purchased plate had been treated differently during manufacturing, with the result that manganese nodules were precipitating out of the alloy, thus making it susceptible to inter-granular corrosion. The result was that newly-built vessels had to be rebuilt and their original hulls scrapped.
