sir,please tell me about naval architecture & marine engineering.what is it's future in india and in other countries.how are the placements going to be for a student from this branch?

Naval architecture is an engineering discipline dealing with the design, construction and repair of marine vehicles. Naval architecture involves basic and applied research, design, development, design evaluation and calculations during all stages of the life of a marine vehicle. Preliminary design of the vessel, its detailed design, construction, trials, operation and maintenance, launching and dry-docking are the main activities involved. Ship design calculations are also required for ships being modified (by means of conversion, rebuilding, modernization, or repair). Formulation of safety regulations and damage control rules and the approval and certification of ship designs to meet such statutory and non-statutory requirements are also included in naval architecture.

Scope exists in shipyards, shipping companies, research institutions, classification societies, statutory bodies of the Ministry of Transport and Shipping, port trusts, ocean engineering companies and as consultants. Naval architects may also join the technical branch of the Indian Navy.

Marine Engineering involves the design, construction, installation, operation and support of the systems and equipment which propel and control marine vehicles, and of the systems which make a vehicle or structure habitable for crew, passengers and cargo.

Marine Engineering is allied to mechanical engineering, although the modern marine engineer requires knowledge (and hands on experience) with electrical, electronic, pneumatic, hydraulic, chemistry, control engineering, naval architecture or ship design, process engineering,steam generations gas turbines and even nuclear technology on certain military vessels.

Marine Engineering on board a ship refers to the operation and maintenance of the propulsion and other systems such as: electrical power generation plant; lighting; air conditioning; refrigeration; and water systems on board the vessel.Marine engineering also embraces other areas such as Autonomous Underwater Vehicle research; Marine renewable energy research; and careers related to the Offshore extractive and infrastructure (Cable Laying) industries.
