Environmentally acceptable lubricants (EAL) in the maritime industry
(Master thesis, 2016)All dynamic mechanical equipment needs lubrication to perform in a best possible way. In the maritime industry, e.g. ships, many of the most important dynamic mechanical systems are located beneath the surface of the sea. ... -
Estimating the Design Parameters of a Highly Skewed Ship Propeller by Automated 3D-scanning
(Master thesis, 2018)Ship propellers have a highly complex surface geometry. Certain design parameters are commonly used to describe this complex geometry. During production of the propeller blades there is a need for measuring the blade ... -
Experimental Study of Hydraulic Accumulator Discharge
(Master thesis, 2018)This thesis aims to identify the behaviour of a 4 l hydraulic bladder accumulator undergoing discharge under various conditions and ultimately shed some light on irregularities that OneSubsea Processing is experiencing ... -
Experimental study of oil-water separation techniques
(Master thesis, 2017)As hydrocarbon reservoirs mature they will increase their production of water, also operators are moving to deeper waters and marginal fields. As a result, the costs of processing and handling increases. Compact subsea ... -
Experiments and Numeric Simulation on Displacement and Flushing of Hydrocarbon Fluid in Subsea Systems
(Master thesis, 2016)With the increasing number of subsea developments in the oil and gas industry, there is a need for more, and reliable, information on how to conduct safe and well informed subsea operations. One of the hot topics today is ... -
Formulation of Enhanced Water-Glycol Lubricants for Offshore Components - The Influence of Thickeners in Environmentally Acceptable Lubricants on the Wear of a Steel Piston Cylinder
(Master thesis, 2016)The service life of offshore stainless steel cylinders used for riser tensioner systems is lower than expected. This is due to the complex degradation mechanisms, like corrosion, wear and fatigue, that take place under the ... -

(Master thesis, 2018)The following activities shall be included in the project: ATI 830 1. Document microstructure and mechanical properties for the received alloy. 2. Execute the test program given in Attachment 1. 3. Execute a literature ... -
Installation and IMR on a subsea production system
(Master thesis, 2017)In recent years, the focus on increased production and reducing operating costs has become an important goal for the oil and gas industry. This trend is likely to be even more important in the future. Installation and ... -
A novel solution for plugging of subsea wells
(Master thesis, 2016)In recent years, Statoil and other operators on the Norwegian continental shelf (NCS) have publicly announced the need for innovation and new solutions that can improve the efficiency, and reduce the cost of plugging and ... -
Possibilities and Implications by Designing an Aluminium Integrated Template Structure.
(Master thesis, 2017)Steel has historically been the governing material for use in subsea applications. This master thesis looks into the possibility of using aluminium rather than steel in subsea structures. A four-slots integrated template ... -
Predictive Maintenance for an Industrial Application - Contribution to Maintenance Modelling Utilizing Petri Nets with Predicates
(Master thesis, 2018)In the current industrial scenario, maintenance activities are recognized as a strategic issue. With the increasing demands of the maintenance organizations, maintenance policies have to ensure that physical assets will ... -
Properties of thermal sprayed coatings for internal use in pipes and bends
(Master thesis, 2015)NTNU/SINTEF are participating in a research project called Smooth Surfaces , financed by Norsk Forskningsråd, and with Brunvoll, Triplex, Omya Hustadmarmor and Aquamarine as industry partners in the project. One of the ... -
Reliability assessment of subsea BOP control systems
(Master thesis, 2015)The subsea blowout preventer (BOP) and the BOP control system were the most important contributors to the Macondo accident in April 2010. A BOP is a large valve system used during the drilling phase; to seal, control, and ... -
Reliability assessment of subsea BOP shear ram preventers
(Master thesis, 2015)The objective of this report is to assess the reliability of blind shear rams (BSRs). The BSR's failure to seal off and secure the well in the Macondo incident proved the necessity of reevaluating the abilities of current ... -
Reliability Assessment of Subsea X-mas Tree Configurations
(Master thesis, 2015)The focus of this thesis is to provide input for choosing the optimal X-mas Tree (XT) configuration for a subsea production system. The subsea XT is used to direct, regulate, and stop the flow from a well. These functions ... -
Reliability of subsea blowout preventer systems - A study of the emergency disconnect function
(Master thesis, 2015)The Deepwater Horizon accident in 2010 emphasizes the significance of safety in offshore drilling. The drilling rig was considered to be reliable and safe, but the blowout in the Gulf of Mexico costed eleven lives and the ... -
Risk-Based Inspection of a Fish Feed Factory.
(Master thesis, 2018)Production equipment is always subject to corrosion and material degradation, e.g. wear and fatigue, when in operation. The extent of deterioration depends on several parameters such as material selection, operating ... -
