The University National Oceanographic Laboratory System (UNOLS) updated their Research Vessel Safety Standards, and specified that new documentation called Maximum Capability Documents (MCDs) are required for each piece of each overboard handling systems. An MCD is intended to describe the structural limits of the individual component.
The wide variety of vessels in the UNOLS fleet, coupled with the undefined loads each of these unique components could be expected to carry in the future, created quite a challenge in providing this documentation. Glosten has supported UNOLS in developing a standardized methodology to analyze all of the potential loading scenarios for each component and then document the analysis in a useful way for future seaman to use intuitively.
Supported by the National Science Foundation, Glosten worked intimately with each of the UNOLS vessel operators to identify the potential range of the components and perform ship checks to verify as-built dimensions. The data were used to build finite element models of each of the components and an automation routine developed in order to analyze the hundreds of load cases identified by each of the operators. The delivered document was a 1-page summary sheet coupled with a booklet of backup data that describes the structural limits of that piece of overboard handling equipment.
Safer Operation for Current and Future Science
Complex analysis was distilled for each of the vessel operators enabling safer operation and clarity for management and seamen. Additionally, Glosten developed a methodology to enable rapid and thorough analysis of each unique component. The client and the vessel operators are satisfied, and MCD development for other components continues for these institutions.
