Estimation of Shallow Water Effects Using Empirical and Numerical Methods for Inland Vessels
Abstract: Due to the increased demand for transportation of cargoes through waterways, there is a need for more and efficient inland vessels. The Inland Waterways Authority of India (IWAI) has planned initiatives to augment the inland waterways sector through strategic development, complementing one activity with others to ensure efficient and effective movement of goods within the country for in-bound and out-bound destinations. A key element of this plan will be the …

Standardization of Design of a Commercial Combination Fishing Vessel in India
Abstract: The sea going boats and ships are designed and constructed based on the rules of the classification societies and the registering authorities of the flag nation. This ensures the structural and operational safety of the vessel as well as the crew and others onboard. The vast majority of the commercial fishing vessels in India are not designed and constructed like this. The standards are not followed in the design and …

Thermo-mechanical Tensioning: A Distortion Mitigation Tool for Shipbuilding Industry
Abstract: Thin plates are widely used in ship building to lower the weight of the hull structure so as to have a gain in pay load as well as to improve fuel efficiency. But the fabrication of the structures involving the thin plates suffers weld induced buckling because of their lower critical buckling strength. So, there is a need to mitigate these weld induced buckling distortions by employing proper distortion control …

Properties in Materials for Ship Frame Structure
Abstract: Materials for ship building select materials for hull and superstructures. Buoyancy, stability, stiffness, resistance to buckling and distortion, corrosions, osmosis into laminates and fire risks are main properties. The aim is to resist distributions of gravity waves, hogging moment of cargo, sagging moment and deflections. Materials selected are iron and steel, aluminium, cupro-nickel, glass reinforced plastics, epoxy laminates, concrete and wood as load carrying members like girders, beams and stiffeners. …

Use of New Materials for Caisson Type Dry Dock Gates in ShipBuilding and Ship Repair Dry Docks: A Review Paper
Abstract: The search for new, more efficient forms of dock gate designs and contemporary trends has led to the construction of increasingly more complex elements including many that still require an economically viable construction system. Caisson type Dry Dock gates need to evolve into a great extent of modernization and to be adapted to the latest technology demands. The use of composite materials could be considered in Dry-Dock gates, particularly in …
