Design Issues and Trends for the New Generation of Offshore Support Vessels

Abstract

Abstract The new generation of offshore support vessels (OSVs) has become increasinglysophisticated and technically advanced in response to demands from deepwaterdrilling and production operations. This paper reviews design issues and trendsfor the development of the next generation of OSVs, highlighting recentlyenhanced classification technical requirements. The new requirements addresssafety criteria and environmental protection for the design, construction andoperation of OSVs. The paper also includes applicable criteria and new notations for eachspecialized service of the OSV including transportation of supplies andequipment, towing and anchoring of offshore structures, well stimulation andtesting, fire fighting, heavy lift, oil spill containment, pipelineinstallation, diving activities and safety stand-by as well as provisions forthe integration of multifunctional services. Additionally, the paper addresses the use of LNG as a fuel for propulsionprimarily to reduce emissions. Introduction Over the years, Offshore Support Vessels (OSVs) have evolved dramatically asshown in Table 1 in terms of diversification, worldwide operation and waterdepth capabilities. This evolution of technology advancement has been driven bythe need to meet the ever-increasing support demands of deepwater drilling, production and subsea operations.
