A simulation-based ship design methodology for evaluating susceptibility to weather-induced delays during marine operations

Abstract

In this paper, we present and test a discrete-event simulation approach for evaluating the inherent susceptibility to weather-induced delays during marine operations as a consequence of limitations in vessel response characteristics. The simulation routine replicates the execution of operations in a long-term perspective by applying weather data time series and vessel response-based operational criteria. Weather windows are taken as the basis for the operation start-up criterion. A case study is presented where we examine the capabilities of the simulation methodology towards reflecting the inherent weather challenges in operational scenarios and the ability to distinguish between alternative design concepts. Comparison is performed towards the percentage operability method and integrated operability factor to uncover advantages of the presented approach. Application of the simulation methodology is found to yield further knowledge of the inherent operational persistence and weather delay susceptibility of proposed vessel designs in the early phases of ship design.

Effective utilization of service vessels in fish farming: fleet design considering the characteristics of the locations

“…Only a limited number of experiments were performed, but they do provide a demonstration of the variations in fleet performance that can result from different weather scenarios. It should also be noted that only one parameter is used to represent weather, and even though significant wave height is often the main consideration with respect to operational limits for vessel operations (Det Norske Veritas AS 2011) , other parameters like wave period, wind, and current are also important (Sandvik et al, 2018;Shen et al, 2019b). Vessel characteristics are not extensively described in the method, only including sailing speed, what operations the vessels can perform, and operational limit.…”

“…That is, how waves can build up before reaching the farm. Left-hand map is retrieved from the Norwegian Directorate of Fisheries ( 2021a) is studied for other maritime industries, including percent operability based on scatter analysis (Gutsch et al, 2016;Tezdogan et al, 2014), the relative rate of operation based on discrete-event simulation (Sandvik et al, 2018), and the operability robustness index (Gutsch et al, 2020). For other segments, such as traditional shipping, the literature also covers long-term operational performance of fleets of vessels in the context of strategic problems such as the maritime fleet size and mix problem (Álvarez et al, 2011;Pantuso et al, 2014;Sperstad et al, 2017), and short-term maritime fleet routing and scheduling (Álvarez, 2009;Lianes et al, 2021;Psaraftis, 2019).…”

Operability analysis of traditional small fishing boats in Indonesia with different loading conditions

“…The work of Gutsch et al (2017) investigated the change of some main dimensions of Offshore Construction Vessels (OCV), such as length, breadth, draught, transversal GM, and radius of gyration of roll (R 44 ) to the IOF value of RMS Roll. Sandvik et al (2018) used IOF for every single criterion of the RMS of heave, pitch, roll, and vertical crane displacement for the OCV. In their research, the combination of some main dimensions of the vessel was also investigated.…”

“…In addition, the guidance introduces a reducing factor, the alpha-factor, which will reduce the weather operability because of the uncertainty of weather forecasts combined with operation durations [48] (B700 therein). Weather-induced delays and weather dependency can be modelled using discrete event simulation techniques [51,52].…”
