“…Early estimates of motions natural frequencies can be made for the three natural frequencies in roll, heave, and pitch based only upon the main characteristics and parameters of the vessel (DnV, 2010), and manoeuvrability acceptance is performed based on the criteria developed in (Barr et al, 1981). The seakeeping operability criteria have been analysed in (Nordenstrom, 1971, Hutchison, 1981, Naito et al, 2006, Ghaemi and Olszewski, 2017 and recently in (Garbatov et al, 2019).…”

The paper covered a study aimed at developing a risk-based conceptual ship design method for bulk carriers, while taking into account the life cycle assessment and energy efficiency of the ship propulsion system. The study included conceptual ship design as a part of the risk-based ship design approach. In such conceptual design, using the long-time experience and statistics, the main dimensions and hull form, resistance and propulsion, weights, initial stability, freeboard, seakeeping and manoeuvrability were initially derived and the capital expenditure, operational expenditure, and decommissioning expenditure obtained. An optimal design solution was obtained, based on the energy efficiency design index, shipbuilding, operation, and resale costs at the end of the service life, which were used as input variables in a riskbased analysis.

“…Limiting values of selected operability criteria are shown in Table 4. Limiting values employed are universal for all ship types, except limiting values of the roll and the vertical acceleration at FP, which are specific for passenger ships [13]. Expressions for calculating operability criteria using response spectra and corresponding spectral moments are provided, e.g., in [18].…”

The method for the prediction of extreme vertical wave bending moments on a passenger ship based on the hindcast database along the shipping route is presented. Operability analysis is performed to identify sea states when the ship is not able to normally operate and which are likely to be avoided. Closed-form expressions are used for the calculation of transfer functions of ship motions and loads. Multiple operability criteria are used and compared to the corresponding limiting values. The most probable extreme wave bending moments for the short-term sea states at discrete locations along the shipping route are calculated, and annual maximum extreme values are determined. Gumbel probability distribution is then fitted to the annual extreme values, and wave bending moments corresponding to a return period of 20 years are determined for discrete locations. The system reliability approach is used to calculate combined extreme vertical wave bending moment along the shipping route. The method is employed on the example of a passenger ship sailing across the Adriatic Sea (Split, Croatia, to Ancona, Italy). The contribution of the study is the method for the extreme values of wave loads using the hindcast wave database and accounting for ship operational restrictions.

“…The level of limit values is also dependent on the type and size of the ship. A summary of the criteria proposed by various researchers for selected seakeeping is provided in (Ghaemi and Olszewski, 2017, Karppinen, 1987and Lloyd, 1989.…”

Ocean routes are recommended for ships based on economic criteria. Under the influence of waves, during the cruise of the ship, dangerous phenomena are created, the intensity of which depends on the speed of the ship and its course in relation to the direction of the waves, the state of the sea, the size of the ship, the state of loading. Although weather services are known, waves parameters are not used to calculate the value of parameters that characterize dangerous phenomena. The article presents the most frequently analysed dangerous phenomena, how they are calculated, the criteria for their evaluation, and the results of calculations for the selected vessel.
