Indian classification society IRClass has released its new technical software, IR-HULL, which evaluates strength and scantling compliance for seagoing steel ships. IRClass said it specifically developed IR-HULL to verify all aspects of ship design compliance to its established rules and regulations for the construction and classification of steel ships. The software, available to ship owners, designers, consultants and shipyards, analyzes global strength (including both longitudinal and buckling strength) and local scantling for all panels and stiffeners in a vessel’s hull section.

Nippon Steel & Sumitomo Metal Corp, Japan's biggest steelmaker, may start talks on a contract to transport iron ore from Brazilian miner Vale on Valemax ships, the world's biggest bulk carriers, to cut costs, a senior official said. Such a contract would be a boost for Vale, which is trying to increase use of the ships after China in 2012 prevented the world's biggest iron ore miner from docking the giant vessels in its ports to protect its own shipping companies. The 400,000 deadweight tonne (dwt) vessels could cut Nippon Steel's shipping costs by at least $400,000 on each cargo.

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.

Amphibious Ship San Antonio to be Christened

The lead ship of the Navy’s newest class of amphibious warship, San Antonio (LPD 17), will be christened during ceremonies July 19 at Northrop Grumman Ship Systems Avondale Operations in New Orleans. Gen. Michael W. Hagee, commandant of the Marine Corps, will deliver the ceremony's principal address. U.S. Sen. Kay Bailey Hutchison of Texas will serve as ship's sponsor. In the time-honored Navy tradition, Hutchison will break a bottle of champagne across the bow to formally christen the ship, named for the city of San Antonio, Texas. San Antonio is the first surface ship ever designed in "virtual reality,” using computer modeling to design most of the ship before any steel was cut.
