Ship Technology Research

The Ship Technology Research (Schiffstechnik) journal seeks to provide a sound and internationally-recognised platform for the presentation and discussion of the latest developments in research, design and manufacture as well as operation and maintenance concerning ships and offshore structures. Engineers and researchers involved in the design and fabrication of ships and offshore structures are the primary audiences of interest. The journal covers applied research in the following topics for ships and offshore structures: • Resistance and propulsion in calm water and in waves • Motions in waves and dynamic stability • Wave loads, extreme and fatigue loads • Fluid-structure interaction, whipping and springing • Manoeuvring in calm water and in waves • Slamming, sloshing and green-water loads • Loads on appendages • Cavitation and ventilation • Ship dynamics in shallow and restricted waters • Hydrodynamic interaction and multi-body problems • Mooring, anchoring and station keeping • Modelling of environment – wind and waves • Development and validation of numerical methods • Model tests and full-scale measurements • Design loads and rule development • Linear and nonlinear structural response for service loads and accidental actions • Novel materials and material modeling including fatigue and fracture • Design method developments and applications with a special focus on risk-based design methods as well as optimization techniques • Design method developments and applications for Arctic conditions • Life-cycle considerations and assessment incl. manufacture, inspection, monitoring, repair and maintenance • Structural dynamics • Strength and fatigue • Mechanics of offshore structures.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

External Cites per Doc

Cites per Doc

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.
