Propulsion Systems Engineering

Leading provider of Propulsion System Dynamic Analysis (PSDA) services to the marine industry.

PSDA, also known as Dynamic Response Analysis, is a design tool used to validate the performance of individual equipment components and their integration into a propulsion system including the associated control algorithms.

Performed to support the development of a propulsion system whose steady state and dynamic performance must be well understood at an early stage in the ship design program, long before construction.

PSDA common practice in the marine industry, particularly for ships that have complex propulsion system architecture and/or a broad range of operational and mission profiles. Gastops PSDA methods provide the flexibility to investigate “what if” scenarios and perform parametric studies that support the ship design process by quantifying system performance and verifying that the system design margins are adequate to cope with the anticipated dynamic loading conditions.

These analyses are an integral part of the design process since they allow system performance estimates to be available during the contract and detailed design phases of the ship program. The analyses are essential in designing and validating machinery control system algorithms, and also provide the added benefit of contributing to the development of training/test support systems and programs.
