... outlining the I3P protocol is included to provide an understanding of the process flow. Several vital I3P review modules contribute to efficiency and are discussed as part of an actual 20,000 psi subsea wellhead system (SWH) plan execution. Other key conclusions include: Operator planning, OEM comprehensive...

...″ wellhead system has been developed to meet those needs. The system was designed and qualified to API 17TR8 with the addition of rigorous internal design and testing requirements. The system design is based on the field-proven technology of a legacy 20,000 psi 350°F 18-3/4″ wellhead system (reference OTC...

... of challenging the thoroughness of wellhead system validation testing. With virtually no ability for operators to standardize on wellhead system configurations (ie, casing sizes, weights, BOP stacks, rigs, riser systems, etc the capability of these systems must be equally comprehensive. Increased flexibility...

A typical wellhead system including wellhead housing, conductor, and casing system is selected for the riser load estimation and the wellhead fatigue assessment using fracture mechanics method is carried out in accordance with API 17TR8...

... for designing and sizing other equipment, such as connectors, risers, BOPs, and casing programs. The typical wellhead systems that the industry currently uses include mandrels with 27 in. and 30 in. OD and conductor casing with up to 36 in. OD. However, these configurations may not be able to resist the high...

... Reducing oil prices, wellhead system performance and regulatory testing requirements are driving the need for efficiencies in the installation, testing and support of well operations worldwide. Wellhead equipment manufacturers provide a critical role in maximizing these efficiencies...

... Abstract As the oil and gas industry moves into drilling and production operations in deeper waters and harsher environments, there is a great demand to develop the next generation of tools and technology to meet these challenges. Subsea wellhead systems form a critical part of the drilling...

... Abstract This paper examines sources of uncertainty in present analysis methodologies used for the prediction of wellhead system fatigue lives. For this study, the sources of uncertainty are classified as those parameters that affect the prediction of loads and stresses ( the demand ) and those...

... Abstract Watch circles are established by operators to ensure a dynamically positioned vessel does not induce loads that exceed wellhead system equipment capacities. In the event the vessel moves off station, beyond the boundary of the watch circle, loads could be transmitted that may approach...

... and data processing methods in the selection and design of the system. The assessment presented here has widespread application across subsea wellhead systems worldwide. A variety of different approaches to monitoring wellhead system fatigue have been attempted. These include motion measurement, using...

..., subsea wellhead systems are an important part of the drilling and production equipment and a proper understanding of their behavior under complex loading conditions is crucial. Component and sub-system analysis and limited testing has been performed before but such analysis and testing does not fully...

... Abstract The specification and selection of subsea wellhead systems is typically based on the use of generic system designs which have a defined extreme load capacity. However the fatigue performance of the wellhead system is also a critical aspect of the equipment which may not always...

... Abstract There is an increasing need for higher pressure and higher temperature rated equipment as wells are being drilled in such reservoirs in deep water subsea fields. This paper presents the development of the first 18-3/4" - 20,000 psi subsea wellhead system rated for 0°F to 350°F...
