Model tests for development and validation of new concepts are a central aspect of MARINTEK’s activity. Complex concepts, with advanced control systems or moorings in very deep water, increase the demand for numerical tools to be used in combination with model tests. Hence, development of new advanced software tools is also important to deal with new challenges.
In 2010, MARINTEK performed a number of studies in connection with Eide Marine Services AS’ recently developed well intervention vessel. The vessel is intended to combine the motion characteristics of rigs in adverse sea states with the mobility of conventional vessels. The main aim of the study was to document the characteristics of the vessel’s dynamic positioning system and its motion characteristics, via a combination of numerical analyses and comprehensive model tests in the Ocean Basin.
In 2010, a large proportion of MARINTEK’s activity on moored floaters in deep water was carried out in connection with the potential development of the Luva field in the Norwegian Sea, where the depth reaches some 1,300 metres. MARINTEK has also tested floater concepts for other fields. In June 2010, we performed a wide range of tests for a semisubmersible moored platform, which was one of the concepts that were evaluated for the development of Midgard on the Åsgard field. These tests were carried out using a segmented model in order to measure hydrodynamic forces on one of the columns and the platform deck.
