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 and a 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. The 6500 m HOV will be designed and constructed to achieve the full spectrum of the U.S. deep submergence scientific community’s diverse and multi-disciplinary requirements which span a range of geographic settings, and seafloor and water column environments. The 6500m HOV will provide unique and state-of-the-art scientific capabilities essential to observational deep- submergence research, and the flexibility to deploy a variety of sensors, conduct in situ experiments, and undertake synchronous observations – all of which are essential to 21st century oceanographic science. Given the scope of the project, WHOI will endeavor to execute this project in accordance with the “intent” of the NSF Large Facilities Manual (LFM) requirements even though this project is not funded through the NSF Major Research Equipment and Facilities Construction (MREFC) account. The Project Execution Plan (PEP) describes how WHOI will manage this project during Stage 1, and provides order of magnitude estimates to achieve Stage 2 of the project. This project is somewhat unusual in that the Preliminary Design Review is being held after construction has begun. The total estimated cost for the preferred Stage 1 A-4500 HOV design is $35,174,894 (including contingency), of which $16,145,537 has been expended on the project as of 31 October 2009. The PEP establishes the roles and responsibilities of the project team members and describes the manner in which the Project will be managed and controlled. The PEP describes the project 1 A-4500 HOV Project Project Execution Pan management tools, techniques and procedures that will be implemented for ensuring that the Project meets its goals and objectives. This first version of the PEP was created to support the Preliminary Design Review and will be modified as the Project moves forward. The philosophy in writing this PEP is to incorporate a number of existing (or planned) supporting documents by reference. This allows the supporting documents to be updated without impacting the PEP. 1.0 Introduction and Background to the 6500m HOV Project Great advances in scientific knowledge that fundamentally improve humanity are born from direct observations. There are many examples of this axiom. What if Thomas Jefferson had opted for some indirect way to explore the American west instead of sending Lewis and Clark on their famous expedition? The richness of that direct experience with the environment, and the direct observations of nature, native civilizations, and the spatial context and continuity of the landforms, rivers, and mountains achieved the historical impact it did precisely because those explorers were immersed in the settings they were mapping and studying. Similarly, to paraphrase Allyn Vine, one of the engineers who developed the Alvin submersible, the Royal Society of London could not have chosen a better ‘instrument’ than Charles Darwin to make observations in the Galápagos Islands. Immersed in the unique natural setting of the Galápagos and observing the birds and other animals interacting with their environment provided the stimulation for his ideas on natural selection. In each of these examples, talented individuals making detailed direct observations changed the course of history and science. Direct observation of the ocean floor provides the last great frontier on this planet for exploration and discovery. Seminal observations made in the late 1970s by scientists using the HOV Alvin in the Galápagos Rift ushered in an entirely new perspective on how animals can adapt and survive in some of the most hostile environments on this planet. This discovery precipitated scientific debate that continues to this day regarding how life-forming processes initiated on this planet and how they may exist elsewhere in our solar system. The discovery of hydrothermal vents and the Figure 1.1 Gray area denotes areas that Alvin can operate. The new 6500m HOV will be able to operate in the gray, yellow and red areas, direct observations of the increasing accessibility to 98% of the seafloor. myriad processes associated 2 A-4500 HOV Project Project Execution Pan with chemosynthetic processes in the deep ocean revolutionized not only the biological sciences but oceanography in general. These discoveries paved the way for over 40 years of focused research along ocean plate boundaries and along continental margins. They have helped establish new lines of scientific inquiry that have had important societal and economic consequences. The deep ocean and seafloor beyond 4500 m water depth (the current limit of the HOV Alvin) is unquestionably the 21st century’s frontier on this planet. The construction of a new 6500 m submersible to replace the HOV Alvin has the same potential as the HMS Beagle that transported Darwin to the Galápagos – the opportunity to explore and make discoveries. With the significant advances in underwater technology, we can now provide the tools to explore and study the diverse properties and processes that are present in that environment. This will undoubtedly provide new and important insights into a plethora of biological, chemical, geological and physical processes. Constructing a new 6500m HOV will ensure that U.S. scientists and students have the means to make direct observations over 98% of the seafloor and the overlying water column – a major improvement from the 65% that is now within reach of the HOV Alvin (Figure 1.1). 1.1 Community Activities Towards a New 6500m HOV Deep submergence science is a diverse field of study involving biological, chemical, geological and physical oceanography. Observations and measurements are made at and near the seafloor, and in the vast mid-water environment from the edges of the continents to the deepest and most remote regions of the world’s oceans. The diverse nature of deep submergence science requires the use of a mix of approaches, platforms, and tools, including human occupied vehicles (HOVs), remotely operated vehicles (ROVs), and autonomous underwater vehicles (AUVs) [Fryer et al., 2002].
