3 New Reports Now Available From Ship Structure Committee
The Ship Structure Committee has available copies of three new reports.
SSC-288, "The Effects of Varying Ship Hull Proportions and Hull Materials on Hull Flexibility, Bending and Vibratory Stresses," is an analytical study which considers four typical vessels—an ore carrier, a tanker, a containership and a general cargo vessel.
With the flexibility of the hull represented by the natural frequency of the ship, a potentially useful relationship between the flexibility and bending moment has been established.
SSC-289, "A Method for Economic Trade-offs of A l t e r n a te Ship Structural Materials," develops a relatively inexpensive and simple method for comparing the relative costs and benefits of using materials other than mild steel in ship construction. The factors considered include useful ship life, construction costs, repair and maintenance costs, together with noneconomic considerations, such as suitability for intended use and trade route, environmental impact, and depletion of natural resources.
SSC-290, "Significance and Control of Lamellar Tearing of Steel Plate in the Shipbuilding Industry," is a useful guide describing the factors which contribute to and influence lamellar tearing, a review of the procedures used to determine susceptibility to lamellar tearing, and methods for postwelding detection and repair of lamellar tears. This type of failure is especially common in fixed and mobile platforms of the type used in the offshore mineral exploration and production industry.
