Conclusions

bull A wellhead system verification analysis and validation test has

been successfully completed and provided better understanding

of the wellhead system performance

bull System validation testing provided critical information needed to

make proper adjustments to the verification analysis methodology

bull Knowledge obtained from this test program is being applied for

HPHT development work of 20 Ksi (or higher) subsea systems

bull A new 35Prime wellhead systemconnector design concept is

presented with structural capacity and fatigue resistance

characteristics expected to meet the HPHT industry needs for the

Conclusions

bull A wellhead system verification analysis and validation test has

been successfully completed and provided better understanding

of the wellhead system performance

bull System validation testing provided critical information needed to

make proper adjustments to the verification analysis methodology

bull Knowledge obtained from this test program is being applied for

HPHT development work of 20 Ksi (or higher) subsea systems

bull A new 35Prime wellhead systemconnector design concept is

presented with structural capacity and fatigue resistance

characteristics expected to meet the HPHT industry needs for the

next decades

bull APQP implementation is key for safe and reliable equipment at

HPHT environments
