Sammendrag
This thesis will focus on the use of optimization algorithms to suggestan optimal bolt placement with regards to deflection. The work isinspired by and supposed to be an addition to the design process thatThomas Røkke and Henrik Hoen Hersleth have been automating. Theinput and output of this program are based on this design process, andthese parameters will be defined and discussed later.The program is supposed to suggest an optimal bolt pattern for subseamanifold applications where the goal is to reduce the separation in andaround hydraulic tubes. The solution to this problem is not necessarilya symmetric bolt pattern and this makes it challenging to establisha simple model to calculate the different deflections. The main focusof this thesis is to establish and design a model that can be used tosuggest a good bolt pattern. The model will be used to design anobjective function that tries to estimate the deformation in each tube,and this objective function can be used in optimization algorithms tofind an optimal solution. The results of the different models will beverified using Finite Element Method (FEM) in the ABAQUS CAEtool.
