Ms. Jacquelin LeBreck, ANL’s Manager of Conference Services added significant value before, during, and after the Workshop. She is responsible for finding and engaging the company that handled the on-line registration. They collected the registration fees from about 140 people with no errors or difficulties. She coordinated with the hotel at the Workshop, to ensure that everything went very smoothly, and that we were billed properly for all of our purchases. The following members of ANL’s Nuclear Engineering Division provided exceptional service to the Workshop: Ms. Brea Grischkat prepared all of the handouts, coordinated all of the registration details, and all of the shipping of supplies and equipment to the meeting. She also compiled all of the documents from the meeting, and prepared the final meeting report.

Ms. Claudia Goddio’s webmaster skills helped us to have a good website and smooth operations in our recruiting and registration process. Ms. Susan Carlo provided significant assistance in the preparations, paperwork and material organization prior to the meeting. Our thanks to all for a job well done! vii viii Executive Summary Effects of Water Depth on Offshore Equipment and Operations Executive Summary On November 2-3, 2011, nearly 140 subject matter experts from the offshore oil and gas industry and federal regulatory agencies, assembled to discuss the “Effects of Water Depth on Offshore Equipment and Operations.” This workshop, referred to as the Effects of Water Depth (EWD) Workshop, was sponsored by the Bureau of Safety and Environmental Enforcement (BSEE) in part to respond to a recommendation made by the Outer Continental Shelf Safety Oversight Board (OSOB) in their September 1, 2010 report to the Secretary of the Interior, Ken Salazar. Specifically, the recommendation was to “consult with technical experts, conduct further analysis of the effects of water depth on equipment and operations, and determine the adequacy of current regulations.” In the eighteen months since the Macondo incident of April 20, 2010, both industry and regulators have worked diligently to understand the events leading to the incident and to implement steps to prevent recurrence. To further this effort, BSEE designed the EWD workshop to draw the offshore drilling arena’s foremost technical subject matter experts in order to collaborate and share their views and recent learning experiences specific to deepwater drilling technical challenges and issues. This included discussion of the need for revised and/or new regulations and industry standards to improve drilling, well control, and oil spill response operations. The EWD Workshop was also the first major public

INTRODUCTION Transocean's Deepwater Horizon offshore drilling rig, on lease to BP, exploded and caught fire on April 20, 2010. This event caused the deaths of eleven workers and resulted in an oil geyser that spewed millions of gallons of oil into the Gulf of Mexico.' The Deepwater Horizon sank two days after the explosion. Nearly three months later, on July 15, 2010, BP was finally able to cap the well.2 The Flow Rate Technical Group, a group of scientists from federal agencies and academic institutions, estimated that * David Pettit, a 1975 graduate of UCLA Law School, is a Senior Attorney for the Natural Resources Defense Council.

    Connecting What’s Needed with What’s Next™ Rod Larson President and CEO Goldman Sachs Global Energy Conference January 9, 2018 Miami, FL Forward-Looking Statements Statements we make in this presentation that express a belief, expectation, or intention are forward looking. Forward-looking statements are generally accompanied by words such as “estimate,” “project,” “predict,” “believe,” “expect,” “anticipate,” “plan,” “forecast,” “budget,” “goal,” or other words that convey the uncertainty of future events or outcomes. These forward-looking statements are based on our current information and expectations that involve a number of risks, uncertainties, and assumptions. Among the factors that could cause the actual results to differ materially from those indicated in the forward- looking statements are: industry conditions, prices of crude oil and natural gas, our ability to obtain and the timing of new projects, and changes in competitive factors. Should one or more of these risks or uncertainties materialize, or should the assumptions underlying the forward-looking statements prove incorrect, actual outcomes could vary materially from those indicated.
