Naval engineering, also referred to as naval architecture is a field of engineering that uses mechanical, electrical, electronic, software, and safety engineering principles to design, build, and operate maritime structures and vessels. Naval architecture comprises both fundamental and practical research, design, development, design evaluation (classification), and calculations at all stages of a maritime vehicle's existence. The vessel's preliminary design, detailed design, construction, trials, operation, and maintenance, as well as launching and dry-docking, are the main operations involved. For changed ships, calculations for ship design are also required. Naval architecture also includes the creation of safety legislation, damage-control techniques, and safety rules, as well as the approval and certification of ship designs to fulfil statutory and non-statutory criteria.Naval engineering, also referred to as naval architecture is a field of engineering that uses mechanical, electrical, electronic, software, and safety engineering principles to design, build, and operate maritime structures and vessels.

The conditions that a vessel confronts while at rest in water and the degree of its ability to float are the subject of hydrostatics. Calculating trim (the measurement of the vessel's longitudinal inclination), buoyancy, displacement, and other hydrostatic properties is required (the ability of a vessel to restore itself to an upright position after being inclined by wind, sea, or loading conditions).
Hydrodynamics
Hydrodynamics deals with the flow of water over surfaces such as a ship's hull, bow, and stern as well as over rudders and propeller blades [1,2].
Ship resistance, which is mostly caused by water flow around the hull, and propulsion are problems with motion on water. This information is used to calculate powering. Propellers, thrusters, water jets, sails, etc. are used to drive a vessel over the water.
Internal combustion is used by the vast majority of engine types. Some ships power their electrical systems with nuclear or solar energy.
Flotation and stability
The distance between the longitudinal meta-center and the centre of gravity affects how stable longitudinal inclinations are. In other words, the foundation for maintaining the ship's centre of gravity is the distance the ship has between its front and aft parts [3-5].
Structures
Structures take into account the choice of building material, structural analysis of the vessel's global and local strengths, vibration of the structural components, and the vessel's structural responses to sea motions. The type of ship, the materials to be used, and the quantity of each will all affect the construction and design. While some ships may be made of glass-reinforced plastic, the majority of ships are likely made of steel, with aluminium perhaps being used in the superstructure.
Steel plates with a rectangular shape are supported on four edges and are used to create the panels that make up the complete ship's structure. The bulkheads, deck, and ship's hull are all simultaneously formed by the grillages when joined over a substantial surface area. The principal force the ship must resist is longitudinal bending, which stresses its hull even though the ship's construction is sturdy enough to keep it together.
Construction
When steel or aluminium is used, the structure is built and launched after the plates and profiles have been rolled, marked, cut, and bent in accordance with the structural design drawings or models. There are several techniques used to link other materials, like glass- and fiber-reinforced plastic. All aspects of construction, including safety, structural strength, hydrodynamics, and ship arrangement, are meticulously studied out. Every consideration provides a new material and ship orientation option. When considering the strength of the structure, acts of ship collision are taken into account in terms of how the structure is affected [6].
The applied material on the struck ship has elastic properties, which allows it to absorb energy while being struck and then deflect it in the opposite direction, causing both ships to rebound in order to limit further damage. For this reason, the properties of materials are carefully taken into consideration. Concept design, layout, and access, fire protection, space allocation, ergonomics, and capacity are all part of arrangements. The hydrostatic pressures are an opposing force that the body must resist in order to float and prevent sinking. In order to keep the body in equilibrium, the forces exerted on it must have the same direction and amplitude. When additional conditions are present, the amplitude of these forces shifts dramatically, causing the body to sway. This description of equilibrium is only present when a freely floating body is in still water.
