Guidance notes on the application and maintenance of marine A tale of two metals - Ocean NavigatorJan 01, 2003 · Steel has a tensile strength of about 50,000 psi. Tensile strength is the ability to withstand static stress loads before tearing. Steel is also very ductile, having typical elongations of some 36 percent (elongation is a measure of steels ability to stretch or deform without rupturing). It also has high resistance to abrasion.

ADVANCED SHIP STRUCTURAL DESIGN AND MAINTENANCE

High tensile steel is frequently used in high stress areas in order to save weight. Structural maintenance aspects are seldom considered during design. Yet this is the stage at which the basis for cost efficient maintenance is established. BNR 197 Splendid Kooiman Marine GroupThis uses high-tensile steel which creates a lightweight structure. The inner bottom is made from the strong and resilient Hardox steel (Swedish Steel), which also saves weight. On the fore and aft ship, above the unladen waterline, several fender boxes have been incorporated in the hull along a length of around five metres. Fracture Mechanics, Fracture Criteria and - Ship Structurein designing welded steel ship hulls of all strength levels. Therefore, the purpose of this paper is to provide rational fracture-control guidelines consistent with economic realities which, when implemented, will minimize the probability of brittle fractures in welded ship hulls. Although the fact is

Preliminary parametric estimation of steel weight for new

Oct 30, 2015 · The standards for steel used in ship design have been raised over time. For example, a bulk carrier satisfying the common structural rules will have a higher hull steel weight ; the hull steel weight also can be reduced by the use of high tensile steel [1, 11]. The parametric estimation method is generally only relevant to the parameters of the entire ship and does not reflect changes in the local Preliminary parametric estimation of steel weight for new The analysis studies important factors to reduce life-cycle costs of ship hull structures, and aims to increase the awareness of the implications of using high-tensile steel in ship hulls.A VLCC Probabilistic Models for Corrosion in Structural Oct 01, 2003 · Economics of High-Tensile Steel in Ship Hulls, Marine Structures, 7 (1), pp. 31

ECONOMICS OF HIGH-TENSILE STEEL IN SHIP HULLS

Abstract During the last decade there has been an increase in the use of high-tensile steel in ship hulls. Initially, high-tensile steel was used in the deck and bottom structure, but lately it has also been used in side-structure and transverse elements. This has given more optimised ships, in terms of both reduced steel weight/investment costs and increased earning potential by increased deadweight.
