Online Presentation on Holistic Design of an Offshore Support Vessel
Joint the T&R presentation by the SNAME (Society of Naval Architects and Marine Engineers) on the “Holistic Design of an Offshore Support Vessel — Parametric Arrangement and Optimization for Damage Stability” held on Wednesday, 22nd September 2021. The webinar will start at 10 AM EST (4 PM CEST) with a duration of 1 hour and 15 min.
The Offshore Service Vessel (OSV) case from the HOLISHIP project has addressed two different vessel concepts with the main focus on power system optimization based on the operational profile of the vessel. Regarded as highly specialized vessels, OSV design requires the synchronization of several of disciplines. Thus, a holistic approach, considering Key Performance Indicators (KPIs) for several disciplines, was developed and utilized starting from a conceptual design level up to the power system concept verification. Independent optimization of each sub-system for different KPIs, without taking into account the interaction between the modules, does not necessarily lead to an optimized overall performance of the vessel and a holistic design approach is highly likely to be beneficial. At the early design stage of a vessel, important parameters are defined, having a huge impact on the performance of the vessel according to the KPIs. Changing these parameters at a later stage in the design process is difficult and requires a considerable effort from the multidisciplinary design team.
This presentation of the holistic design process within the OSV application case is focused on the vessel’s tank arrangement with regards to damage stability criteria. A parametric arrangement methodology was created, integrated with damage stability criteria calculated for this vessel type, and an early-stage automated optimization of the tank arrangement was executed. The methodology is under utilization in other research projects and selected commercial projects.
