Task 1.7 | Data collection needs: who collects the failure data; when is the failure data collected; when, to whom and how is the failure data reported? | Chapter 2, Fastener Life Cycle Chapter 5, Testing Protocol |
Task 2 | Design issues and human-systems interaction factors. This analysis will not be limited to the technical components but will also encompass the entire system and bolt lifecycle (design, procurement, manufacturing, installation, maintenance, commissioning, and operation), including the human components. Specific emphasis will be placed on the management of the manufacturing process from the first tier OEM down through the second, third, fourth, etc., sub tier subcontractors. | Chapter 2, Fastener Life Cycle Chapter 4, entire chapter |
Task 3.1 | Options on improving safety of offshore drilling and pipeline operations as related to the use of fasteners for critical drill through equipment components like the lower marine riser package (LMRP) (connector) and pipeline fasteners. | Chapter 2, Fastener Life Cycle Chapter 3, Fastener Standards and Specifications |
Task 3.2 | Identify options for reducing or eliminating the identified gaps for fastener manufacture, and provide valuable insight on how/if alternative fastener designs are capable of improving safety of offshore drilling and pipeline operations. | Chapter 2, Fastener Life Cycle Chapter 5, New Fastener Designs Chapter 5, Coating Technologies |
Task 3.3 | Options on the methodology for the selection for material properties (such as hardness, yield, UTS, etc.), and other critical parameters identified by the industry standards or codes, in accordance with the subsea bolt application and operating environment | Chapter 2, Options for Improving the Selection of Bolting Material Properties |
Task 3.4 | Options encompassing the use of both domestic and international standards and regulations that are in place today on fasteners to BSEE on how to proceed or how the existing industry standards should be modified to address project findings, or how BSEE should structure a 30 CFR 250 regulation to require these conditions should be met. | Chapter 2, Fastener Design Chapter 3, Fastener Standards and Specifications Chapter 3, Quality Assurance Options Appendix J |
Task 4 | Evaluation of the performance of fastener systems currently in use including the process of manufacturing (e.g. smelting, casting, drawing, heat treatment, coatings, mechanical/material properties, performance properties-shear stress, fatigue life, etc.), corrosion protection (cathodic protection) installation (e.g., torqueing), maintenance and inspection processes associated with fastener systems. | Chapter 2, entire chapter Chapter 4, Human Systems Integration and Fasteners Chapter 4, Human Interactions with Subsea Fasteners Appendix J |
