Science Traceability Matrix 63  \nExecutive Summary  \nWoods Hole Oceanographic Institution (WHOI) will design and build a replacement for the current Human Occupied Vehicle (HOV) Alvin under a Cooperative Agreement with the National Science Foundation. WHOI expertise, in conjunction with expertise acquired from other engineering and management groups inside and outside the Institution, will be used to execute this Project. WHOI will design and build an HOV with a 6500 m depth capability in two stages to be consistent with available technology and funding. During Stage 1 (hereafter referred to as the A-4500 HOV Project), the 4500 m-rated DSV Alvin will be significantly enhanced anda new, larger personnel sphere currently under construction will be installed. This new sphere will allow for larger fields of view for scientists, including complete overlap with the pilot ’s view of the deep ocean and seafloor, thereby immediately providing a significant improvement over the existing Alvin’s capabilities. In addition, the A-4500 HOV will have new interior electronics, improved lighting, and advanced camera and video systems. The new command and control system will increase efficiency and productivity of vehicle operations. In Stage 2 (hereafter referred to as the A-6500 HOV Project) , as additional funding becomes available and lithium ion battery technology matures and is proven for safe use in human-occupied vehicles, the changes necessary to increase working time and extend the depth rating of the submarine to 6500 m would be accomplished.  \nThe 6500 m HOV will be designed and constructed to ","cbCaiaQ2Ge7pQml0","https://ap.wps.com/l/cbCaiaQ2Ge7pQml0","pdf",14573482,72,"English","# Executive Summary\n# 1.0 Introduction and Background to the 6500m HOV Project\n# 2.0 Science Mission Requirements\n# 3.0 Progress to Date\n# 4.0 Vehicle Design and Construction\n# 5.0 Project Management\n# 6.0 Transition to Operations Plan\n# 7.0 References and Supporting Documents\n# Appendix A\n# Appendix B","[{\"question\":\"What is the purpose of the Project Execution Plan for the 6500 m HOV program?\",\"answer\":\"It describes how WHOI will manage the project during Stage 1 (A-4500 HOV) and provides order-of-magnitude estimates to reach Stage 2 (A-6500 HOV).\"},{\"question\":\"What are the main Stage 1 enhancements for the A-4500 HOV?\",\"answer\":\"Stage 1 focuses on significantly enhancing the 4500 m-rated Alvin and installing a new, larger personnel sphere, along with updated interior electronics, improved lighting, and advanced camera and video systems plus a new command and control system.\"},{\"question\":\"Why is the Preliminary Design Review being held after construction has begun?\",\"answer\":\"The plan states the program is somewhat unusual because the Preliminary Design Review occurs after construction has started.\"}]","6500m HOV Project Stage 1 - A-4500 HOV Project Execution Plan | PDF",1789253083,25]
