Probabilistic Design of Midship Panel based on Model scale compressive Ice Test
Neumann, Karoline Mali (Master thesis, 2013)This thesis is investigating compressive ice loads acting on the mid-ship using a model experiment performed in Aalto ice tank where atactile sensor was mounted on the side. In order to get insight in thevery complex ... -
Risk of collision between service vessels and offshore wind turbines
Dai, Lijuan; Ehlers, Sören; Rausand, Marvin; Utne, Ingrid Bouwer (Journal article; Peer reviewed, 2013)Offshore wind farms are growing in size and are situated farther and farther away from shore. The demand for service visits to transfer personnel and equipment to the wind turbines is increasing, and safe operation of the ... -
Steel weight optimisation with respect to stiffener spacing and plate thickness of mid ship structure for cargo vessels
Stokkeland, Lina Marie Storås (Master thesis, 2013)When building a ship, the weight and cost are important factors. By reducing weight there will be more cargo capacity which ensures the income for the ship owner. On the other hand, creating light weight structure often ... -
Ultimate Strength and Capacity Assessment of Ice Class Vessel Operating in Ice
Mork, Håkon (Master thesis, 2016)In an ongoing project between DNV GL and a customer, the ultimate strength and damage on a ship exposed to ice loading are to be assessed. The vessel has the DNV GL class notation Ice(1A*), but is now considered for operation ... -
Virtual Prototyping for Marine Crane Design and Operations
Chu, Yingguang (Doctoral theses;2018:10, Doctoral thesis, 2018)Marine crane system design is an interdisciplinary process involving such as mechanical design, kinematics, multi-body dynamics, hydraulics, and operational control-related tasks. Marine crane operations are inherently ... -
Virtual prototyping for maritime crane design and operations
Chu, Yingguang; Hatledal, Lars Ivar; Zhang, Houxiang; Æsøy, Vilmar; Ehlers, Sören (Journal article; Peer reviewed, 2018)This paper presents the implementation of the virtual prototyping system for maritime crane design and operations. The study is designed to bridge the following gaps in maritime crane system simulations. First, the virtual ...
