Research Cargo Ship

Project: CS1 - Cargo Operations Studio

Status: Running
Contact: Tomas Olsson-Neptun
Description: Development project of a virtual simulator for simulation of cargo operations and load handling. The simulator is used for education, training and research purposes.

 


Project: CS2 – Structural integrity analysis of critical elements of RoPax ships

Status: Finished 2008 (Doctoral thesis can be ordered) 
Contact: Associate Professor Jonas Ringsberg (head supervisor); Dr Ulf Karlsson (former doctoral student in the project). 
Description: Development of a “collision-resistant” side-shell structure suitable for RoPax ships which allows for large scale deformation and deep penetration in the struck ship before the inner-side shell is fractured.

 


Project: CS3 – Hasard/Marine structures

Status: Running
Contact: Associate Professor Jonas Ringsberg (head supervisor) and Mr Per Hogström (PhD student).
Description: The objective with the project is to develop a comprehensive calculation procedure which quantitatively can be used for study of ships survivability caused by collision damage,incorporating: (i) structural collision resistance, (ii) structural stability and collapse, and (iii) ship flooding and stability in waves. The project is divided into twp tracks: marine structures (CS3) and seakeeping (CS9).

 


Project: CS4 – Ship routing and fatigue analysis of container ships

Status: Running
Contact: Associate Professor Jonas Ringsberg (head supervisor) and Mr Zhiyuan Li (PhD student).
Description: Fatigue analysis of container ships is analysed numerically by hydrodynamic and finite element analysis. Global screening for fatigue damage is carried out followed by local fatigue analysis in order to propose another ship route which results in less accumulated fatigue damage (in total or locally) and safer transportation (less risk for fatigue fracture). Close collaboration with project CS5.

 


Project: CS5 – Optimisation of ship routing with respect to fatigue and fuel consumption

Status: Running
Contact: Associate Professor Jonas Ringsberg (supervisor), Professor Igor Rychlik (head supervisor) and Mr Wengang Mao (PhD student).
Description: A numerical tool useful for fatigue routing and less fuel consumption is being developed. Statistical models for sea state conditions, fatigue evaluation and climate changes are utilised. Close collaboration with project CS4.

 


Project: CS6 – Lightweight design using composite structures

Status: Running
Contact: Associate Professor Jonas Ringsberg (head supervisor) and Mr Måns Håkansson (PhD student).
Description: To explore the benefits and potential of using composite materials in structures of commercial vessels.

 


Project: CS7 – Methods for large amplitude ship motions in waves

Status: Running
Contact: Associate Professor Carl-Erik Janson (head supervisor) and Mr Martin Kjellberg (PhD student). 
Description: Numerical tools are being developed for the simulation and analysis of large ship motions and seakeeping in waves. The method should be utilised to predict a ship’s seakeeping attributes (i.e. ship motions, velocities and accelerations). The practical application can be, for example, to assess safety and comfort for crew and passengers.

 


Project: CS8 – Ship manoeuvring in waves

Status: Running
Contact: Associate Professor Carl-Erik Janson (head supervisor) and Ms Heng Ran (PhD student) 
Description: Numerical tools are developed for the simulation and analysis of manoeuvring in waves. Damaged ship stability and manoeuvrability will be studied by simulations.

 


Project: CS9 – Hasard/Seakeeping

Status: Running 
Contact: Associate Professor Carl-Erik Janson (head supervisor) and Lic Eng Martin Schreuder (PhD student).
Description: The objective with the project is to develop a comprehensive calculation procedure which quantitatively can be used for study of ships survivability caused by collision damage,incorporating: (i) structural collision resistance, (ii) structural stability and collapse, and (iii) ship flooding and stability in waves. The project is divided into twp tracks: marine structures (CS3) and seakeeping (CS9).

 


Project: CS10 – Requirement management in ship design

Status: Running 
Contact: Professor Olle Rutgersson (head supervisor) and Lic Eng Ingar Malmgren (PhD student). 
Description: Systems engineering principles are used to study and assess the ship design process from a requirement management point of view. The project is carried out in the ship industry, with the aim to bring forth new experience and knowledge on requirement management in practice.

 


Project: CS11: Fatigue and ageing of lightweight structures

Status: Start of project: 2009-11-09. End of project: 2014-10-31 
Contact: Jonas Ringsberg (Professor; Project Manager). 
Description: The present project is part of the EU-project BESST, Breakthrough in European Ship and Shipbuilding Technologies. 
Investigation of composite structures (fibre reinforced polymers) as innovative lightweight materials and their possible application in ship building of large commercial vessels. 
Detailed investigation of the properties and characteristics of various composite structures will be carried out by experiments at SP Technical Research Institute of Sweden in Borås. 
Numerical models (using the finite element method) will be developed that can mimic the characteristics of the various tests, both for virgin, aged and fatigued structures/materials.
Maintenance and repair methods will be incorporated in the study together with LCA and LCC analysis.
