Ship Design

SimFWD provides to customers integrated ship design and engineering services in Maritime / Offshore and Shipbuilding projects of different types and size. Our range of services starts from the concept idea until the ship is put in service and continues through life-cycle service as maintenance, repair and conversion.

We have the ability to address the all steps of the design and engineering processes with high quality. Concept Design is the starting point of the project where we define main characteristics with the aid of state of the art software and statistical databases. Basic Design is then developed according to national and international rules and verified by advanced engineering analyses. Detailed Design comprises all engineering and construction documentation for the Shipyard. Finally, Engineering Management services include supervision, management, budgeting and operational works of the project assuring quality and schedule.

Conceptual design

Conceptual design phase includes a group of works and processes where all documentation that describes and guarantees the ship according to customer’s needs is generated.

Basic design

Basic design stage inherently contains the conceptual and contractual design phases. This is the most important stage in the ship design project. In the scope of basic design, SimFWD undertakes all necessary engineering work which comprise of arrangement of spaces and equipment, structural design, compartmentation and intact /damaged stability, exterior design and finally hull-form optimization for performance. Using wide experience on numerous ship design projects for different ship types of various sizes and state of the art software tools, SimFWD presents high quality basic design services to its customers.
