A Boundary Element Method Applied to Strongly Nonlinear Wave-Body Interaction Problems
Sun, Hui (Doktoravhandlinger ved NTNU, 1503-8181; 2007:141, Doctoral thesis, 2007)A two-dimensional Boundary Element Method (BEM) based on potential flow theory is developed to study wave-body interaction problems with strongly nonlinear effects. In particular, the following problems are studied. One ... -
A Decision Support Methodology for Strategic Planning Under Uncertainty in Maritime Transportation
Abusdal, Håvard (Master thesis, 2012)Measured in volume approximately 80 % of world trade is carried at sea and with just as many different actors the shipping industry acts close to a perfect market. The highly volatile nature of the industry with unexpected ... -
A Decision Support Model for Merchant Vessels Operating on the Arctic Sea
Sørstrand, Svenn Sætren (Master thesis, 2012)With the ice cap diminishing rapidly on the Arctic Sea, the opportunity of using the Northern Sea Route (NSR) increases correspondingly. However, the climate and presence of ice on the NSR sets additional requirements, ... -
A framework for cost-benefit analysis on use of condition based maintenance in an IO perspective
Børresen, Christian Steensland (Master thesis, 2011)The maintenance costs of an offshore production platform make up about 30 % of the daily costs, and this is not including the cost of shutdown caused by functional failure. Reducing the maintenance costs will have a great ... -
A higher-order boundary element method and applications to marine hydrodynamics
Grytøyr, Guttorm (Doktoravhandlinger ved NTNU, 1503-8181; 2008:170, Doctoral thesis, 2008) -
A Modular Design Methodology for OSV Accommodation Areas
Kawser, Zahid A.S.M. (Master thesis, 2012)Offshore shipbuilding industry is known for its highly customized products, which are in most cases tailor-made for specific missions. Being a traditionally conservative industry, it follows conventional design practices. ... -
A New Small-Scale LNG Distribution and Bunkering Facility: - An Approach to Risk Based Design and Verification
Steine, Caroline Mortmannsgård Gams (Master thesis, 2013)LNG is the preferred solution to meet environmental requirement and a great market growth is expected within few years. Lack of suitable infrastructure, regulation and bunkering practices poses challenges to the industry, ... -
A Numerical Study of a Damaged Ship in Beam Sea Waves
Kong, Xiangjun (Doktoravhandlinger ved NTNU, 1503-8181; 2009:268, Doctoral thesis, 2009)An important objective of survivability criteria for passenger vessels is to ensure that there is sufficient time called Time To Capsizing (TTC) to evacuate passengers and crew members in case of emergency. This requires ... -
A Numerical Study of Wave-in-Deck Impact using a Two-dimensional Constrained Interpolation Profile Method
Vestbøstad, Tone M. (Doktoravhandlinger ved NTNU, 1503-8181; 2009:153, Doctoral thesis, 2009)A Constrained Interpolation Profile method following Hu and Kashiwagi (2004) is developed for wave impact applications. Two-dimensional, unsteady, viscous and incompressible flow is assumed. The numerical model is a finite ... -
A reliability study of a Deepwater Vertical Xmas Tree with attention to XT retrieval rate
Stendebakken, Oda Ingeborg (Master thesis, 2014)The focus of this thesis is towards the subsea Xmas Tree (XT) system. The XT is recognized by the industry as an overall reliable configuration, but as in all development projects, it is a constant battle to optimize the ... -
A simulation-based decision support tool for arctic field logistics
Ulstein, Mads (Master thesis, 2014)As the global demand for energy continues to rise, the oil and gas industry investigates new opportunities for oil and gas production in more remote areas. Promising estimation of oil and gas reserves in the Arctic areas ... -
