A meta-model for added resistance in waves
Kim, YoungRong; Esmailian, Ehsan; Steen, Sverre (Peer reviewed; Journal article, 2022)In this paper, we perform a comprehensive study of various semi-empirical methods using publicly accessible experimental data on added resistance in waves with different ship types and conditions. Based on the analysis ... -
A new method for optimal ship design in real sea states using the ship power profile
Esmailian, Ehsan; Steen, Sverre (Peer reviewed; Journal article, 2022)Typically, ships are designed for calm water and a constant design speed. However, a ship experiences different speeds and sea conditions over her lifetime. Following the significant correlations between environment and ... -
A new power prediction method using ship in-service data: a case study on a general cargo ship
Esmailian, Ehsan; Kim, Youngrong; Steen, Sverre; Koushan, Kourosh (Journal article; Peer reviewed, 2023)To increase energy efficiency and reduce greenhouse gas (GHG) emissions in the shipping industry, an accurate prediction of the ship performance at sea is crucial. This paper proposes a new power prediction method based ... -
Optimal Ship Design for Operating in Real Sea States
Esmailian, Ehsan (Doctoral theses at NTNU;2023:118, Doctoral thesis, 2023)Currently, ship designers are under increased pressure to provide energy-efficient designs and reduce greenhouse gas emissions. For a long time, ships were mostly designed and optimized for operation in calm water. However, ... -
Ship design for real sea states under uncertainty
Esmailian, Ehsan; Steen, Sverre; Koushan, Kourosh (Peer reviewed; Journal article, 2022)A ship is designed under inescapable uncertainty. Neglecting important uncertainties might lead to suboptimal designs. Furthermore, to achieve the best possible performance, the ship design should be optimized for the ...
