Life Cycle of a ship

Programme Topics:

Commercial Ships

The decision to own a ship or charter is more of an art than a science! In certain shipping markets like liner shipping, it is more common to find owned ships whereas in some other markets like dry bulk and liquid bulk, chartering is more common. When you decide to buy a ship, you can buy a new one or old one. The new ship by placing the order with the ship yard who will design and construct the ship to suit your requirement. The old ship having all their valid certificates can be brought from the market. Then the ship has to be registered in a Port of a Country or keep running the ship under same where it has been registered when you have bought the ship. Will discuss more about ship’s registration in the next topic.

Ship design engineering

Well defined objectives are met by the design of a ship which is a creative process. The design engineering of a ship is more than the study of naval architecture alone though it is based on the science of naval architecture. Naval architecture consists inter alia a number of quite distinct subjects like structural strength, trim and stability, resistance and propulsion. Ship design requires the designer to keep the essentials of all these separate subjects of naval architecture and indeed a number of other factors in mind at one time so that a ship concept can be synthesized which both in its main dimensions and in its general arrangement satisfies or comes close to satisfying all the requirements. If the ship designer can do this successfully from the start of a project, the costs, time and effort required to produce a design will be greatly reduced. Otherwise the design is likely to require major changes as it is developed and detailed calculations can be made.

Procurements and Contracts in Ship Building

Procurement and Contracts regarding the building of ships do not fall within the competence of the shipyards. Many assembly and installation operations are, however carried out by their suppliers. In most cases, the logistics become an issue order to manage a Just in Time Inventory. The European equipment manufacturers contribute towards improving the logistics between the complex network of suppliers and shipyards leading to more effective management and allowing the assembly process of manufactured goods to be conducted as efficiently as possible.

Ship Construction

It is not uncommon for competent Masters & Chief Engineers to find themselves confused and amazed in a shipyard. Following is an attempt to explain basic ship construction with special emphasis on Shell Plate Drawings, Bottom & Side Shell arrangements, Ship construction materials, Plate Bending methods and brief description of Shipbuilding Process Flow. Care has been taken to explain structural terms and components through drawings and simple definitions for clearer understanding. A more detailed description of Shipbuilding Process Flow will certainly be of great interest to the readers and its simplified version is discussed; Another important aspect of shipbuilding is the Shipyard Quality Standard based on the guidelines of IACS Shipbuilding and Repair Quality Standards. For senior management personnel engaged as Owner’s representatives in shipyards, an awareness of these guidelines is paramount. This course has been prepared keeping the above two points in mind, and the contents are written in a simple way to make the course interesting.

Operation at Sea

Efficient ship operation is essential for cleaner voyages at sea and in port. Ships should be well maintained / modernized to guarantee maximum efficiency and to keep up-to-date with international and European legislation with regard to the environment. We will discuss the following under this


The European Marine equipment sector is very diverse and it has substantial know-how about components and systems. Therefore, it has a unique advantage to remain the maritime technological pacemaker by keeping their ability to integrate various different systems improving the energy efficiency of maritime transport to a sustainable level.

Shore Management

The Ocean going Ship, whatever may be the type of Ship and the crew can not operate in isolation, while running the ship. They always need their Office to support them in efficient running of the ship. The following figure depicts the total work

Decommissioning and Recycling of Ships

The end of the life-cycle of a vessel is naturally relevant to the environment. While recycling normally takes place far from the influence of the equipment manufacturer, the choice of materials and the design of marine equipment and ships can help minimize the impact of decommissioning. Much of the equipment on board a ship can survive the ship itself, and remain useful after the vessel itself has been scrapped. It must be remembered that up to 98% of a ship can be recycled in comparison to less than 60% of an airplane.
