Design, Testing and Analysis of a New Pipeline Recovery Tool
Eriksson, Nicolai Bull (Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-06-15)Pipeline Recovery Tools (PRT’s) are used in decommissioning and recovery of subsea pipelines. The PRT often use a mechanical system to insert and lock itself onto the subsea pipeline. This thesis examines a unique connection ... -
Dynamic Analysis of a Floating Fish Cage with Feeding Systems
Bruset, Mathias (Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-06)Aquaculture is one of the fastest growing industries in Norway, and one of the fastest growing food production industries in the world. Limited access to available locations along the coast is gradually forcing aquacultural ... -
