What is a doubler? Boat Design Net

May 24,2011 Doubler Plates of Ship Structures#0183;In modern construction doubler usually refers to skin plating rather than frames.Long ago wooden ships often would have the planking doubled when the original planks were old or worn..Today classification rules call for extra skin thickness at point loads and stress risers,places in the structure like a hatch corner or the skeg root..such loads on the skin can be handled with extra What is a doubler?

Strength of Ships' Structures - William Muckle - Google

The book by Muckle can be considered a classic in ship structures since it was published in 1967 by Edward Arnold (Publishers) Ltd.,London.The chapter (8) on theory of plates can be considered still relevant which is very much based on the book by Timoshenko,Theory of Plates Shells.Chapters in the book included materials used in ships Strength Evaluation of a Doubler Plate of Ship Structure The characteristics of stiffness and strength variation are discussed based on their results.A1so,in order to compare the doubler structure with the original strength of main plate without doubler,a simple formula for the evaluation of the equivalent flat plate thickness is derived based on the additional series analysis of flat plate structure.Shipboard Plate and Construction Terms - Cult of SeaA Frame A support structure to provide rigidity to the shaft of a twin-propeller construction.It is shaped like a turned-over A,hence its name,where the propeller shaft is supported at the apex of the structure.Aft Peak Tank A water tank set right aft of the vessel.It will either be a designated freshwater tank or a ballast water tank used for adjusting the ships trim.

Effectiveness of Doubler Plates as a Permanent Repair

Effectiveness of Doubler Plates as a Permanent Repair Under Cyclic Loads in a Highly Corrosive Environment Ship construction represents one of the more challenging planning problems in industry today. The feasibility of developing software tools for automatic assembly planning and detailing of ship structure and outfitting and automatic Doubler plates are used as one of the solutions for plate damage from corrosionin the structures of the ships.Doubler plates are also called doublers.
