Ship design process


The development of a new ship design is carried out in three steps. The first one is the Basic Design with aim to create a baseline concept of the new vessel that satisfi es the shipowner’s requirements. At this step, the Preliminary General Arrangement Plan and a short description of the vessel are prepared.

In order to carry out the Basic Design it is necessary to defi ne the following items:

1. Types of cargo intended for transport

2. Requested cargo capacity

3. Restrictions for main dimensions if any

4. Required service speed

5. Endurance

6. Class Society and ship class

7. Required number of cabins

8. Cargo handling equipment

9. Type of hatch covers

10. Other requirements.

The second step is the Contract Design with the aim to develop detailed contract plans and specifications necessary to calculate the price of the vessel and to sign the Contract with a shipyard. Usually the scope of the Contract Design for a container vessel is as follows:

After signing the contract with a shipyard, it is possible to carry out the Technical Design which contains all drawings, documents and calculations to be approved by a class society, national authority and shipowner.
