16. Holistic Assessment of Survival Time after Ship Collision
Sammanfattning : Collisions between ships contribute to ship losses even in modern time, and the International Maritime Organization (IMO) strives towards a more risk-based view on addressing the damage stability of ships. This thesis presents a holistic methodology for computing the consequences of ship collisions. LÄS MER
17. Roughest hour – approaches to ship hull fouling management
Sammanfattning : Submerged surfaces at sea are colonized by a high diversity of sessile (i.e. attached) life forms. As the merchant fleet capacity increases, responding to growth in demand for seaborne transport, so does the hull wetted surface area that is prone to colonization by these sessile organisms, i.

18. Voyage optimization algorithms for ship safety and energy-efficiency
Sammanfattning : Currently, over 90% of the world’s trade is transported by sea. The environmental impacts from shipping and societal challenges of human and property losses caused by ship accidents are pressuring the shipping industry for more energy efficiency and enhanced safety. LÄS MER
19. Fatigue Assessment and Extreme Response Prediction of Ship Structures
Sammanfattning : In this thesis, a simplified narrow-band approximation model is proposed to estimate fatigue damage of ship structures, and an efficient method for extreme response predictions is also developed using upcrossing spectrums of ship responses. The proposed fatigue model includes two main parameters, significant stress range hs and zero upcrossing frequency fz. LÄS MER
20. Characterising turbulent ship wakes from an environmental impact perspective
Sammanfattning : The world’s oceans, especially coastal areas, are intensively trafficked by ships. All these ships exert pressure on the marine environment, through emission to the atmosphere, discharges of pollutants to the water, and physical disturbance through energy input. Of these impacts, energy pollution from shipping has received the least attention. LÄS MER
