| Abstract | The aim of this paper is to illustrate the main relationship between the independent variables that heavily contribute to fleet resizing. Commonly a shipping company has a fleet for transporting the goods from one port to another around the world. This fleet consists of a group of carriers that transports a fixed amount of cargo between two ports over a period of time and for a fixed cost. The number of carriers in the fleet is heavily dependent on the amount of goods to be delivered annually as stated in the contract. The number of carriers can vary according to the size and speed of the vessels. In addition, fleet operations, scheduling, routing and fleet design can contribute to the development of the overall configuration of the shipping fleet. Specialised long haul carriers with known operating routes such as liquefied natural gas (LNG) carrier transportation depends on the following factors: the ship's daily running costs, voyage costs, costs at sea, costs at port and daily lay-up costs, as well as the number of round voyages per year, lay-up costs of the carrier and number of lay-up days per year. It is clear that there are many different input parameters that are required for fleet optimisation. The objective of fleet optimisation is generally to find the ideal number of ships to deliver the goods according to the contract and to reduce overall fleet costs. The costs are referred to as capital and operational costs. The capital costs or initial expenses are all of the costs that are incurred prior to the commissioning and entry into service of the LNG carrier. Meanwhile, other fixed and variable costs, or future expenses, are all costs that are incurred after delivery of the vessel. However before carried out any fleet optimisation, comprehensive study regarding relationship between all the parameters that affect the fleet size should be established. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
