The ship lifecycle
The life cycle of a ship will typically experience four main stages of ‘life’, namely; design, construction, repair and conversion, and end of service. When purchasing a ship it may be important to know the ships ‘life’ up until the current date of purchase to ascertain the strength and reliability of the ship. If the ship was designed by a credible naval architect you will have confidence in the overall infrastructure of the ship.

Ship life cycle explained
There are several stages of life in which a ship will go through however these stages can be categorized into four main areas. The life cycle is as follows;
Design
This is the initial stage of life for a ship. Typically, this stage will involve the ship owner, designers and ship yard where the vessel is to be built. A naval architect will perform the design for the ship and once the ship is fully constructed it can be launched for service.
This stage is imperative to get right and requires comprehensive analysis and research of ideal ship specifications, dimensions and general ship layout. It should be noted that the ship design must comply with relevant laws and marine regulations in place.
Construction
The construction stage is vitally important in terms of compliance with necessary health and safety regulations, marine standards and other requirements that will render the ship suitable for service. Ship construction will almost always be carried out in a ship yard and can take up to several years to complete the construction. The size and structure of the vessel will influence the length of construction time and also how the building will be conducted. Once construction is completed the ship is launched in the water.
Repair and Conversion
Ships require regular repair and maintenance to ensure they are consistently seaworthy and safe for navigation in waters. If a ship has a particularly active service it will require more repair and maintenance work than a ship used for infrequent chartering, also the weather conditions and distance the ship undergoes will influence the number of repair services it must have. Not all ship repairs and conversions are carried out in a ship yard, some forms of repair can be performed while the ship is stationary in the water. It should be noted that depending on the type of ship you have and its use, it may require visits to dry docks and other types of marine specialized facilities.
End of Service
The final stage of a ships life cycle is known as its ‘end of service’. Ships will typically end up in one of a number of ways – ship museum, scrapped, as breakwaters or artificial reefs, although some unfortunate ships may end up at the bottom of the ocean as a result of collision, extreme damage or grounding. The life expectancy of a ship is normally between 20-40 years depending on the material of the vessel, its use and maintenance.
