Fingerprinting the ship propulsion system: low hanging fruit or mission impossible?

In this paper the concept of ship propulsion system “fingerprinting” is explored as an alternative for data driven models that require extensive measured datasets collected over long periods of ship operation. As a first exploratory step a model of a ship in bollard pull conditions is linearised and its transfer functions are determined....

Uncertainties and Margins in the Ship Propulsion System Design Process

An important aspect for a new-built vessel is the contract speed. Not reaching the contract speed can lead to penalties for the shipbuilder and dissatisfaction for the customer, while an under-predicted contract speed can lead to non-competitive design and a lower income for the shipbuilder. The performance of a new-built vessel is uncertain due...

System design as a decisive step in engineering naval capability

Both costs and capability of naval ships are mainly determined in the early phases of design. The increasing power of computers and sophistication of simulation packages offers the challenge to create more different system designs in an early stage of ship design with a higher level of engineering detail, as well as the challenge to develop...
