Section 7 – Global Design and AnalysisWhat’s Differentz Organization of materialzEmphasis on probabilistic long term responseanalysis for design verificationWhat’s NewzExplicit criteria for minimum deck clearanceand minimum tendon tensionzSingle event fatigue checkzCommentaries on– VIV– high frequency TLP responses– long term analysis and response-based criteriaAPI Workshop on RP2T – Tension Leg Platforms – September 200741
Design Verification PhilosophyAs before z Design checks are structured around the concept of global performanceload cases or limit stateszzzResponse analysis and design checks are based on working stressdesignThe “extreme” design load cases are based on appropriate safety factorsapplied to the estimate of a 100-year return period responseIt is the designer’s responsibility to ensure appropriate environmentalconditions for a site and for a general TLP configurationBut now zRegardless of the way environmental criteria are selected for preliminarydesign, the adequacy of the environmental criteria should be verifiedthrough long term response analysis applied to the final designconfigurationAPI Workshop on RP2T – Tension Leg Platforms – September 200742
EXTREME VALUE FOR DESIGNAPI Workshop on RP2T – Tension Leg Platforms – September 200743
Long Term Response AnalysisInvolves developing non-exceedance probability distributions for TLPresponses of interest that account for both short-term and long-termvariability in sea conditions, and from which design level responses can beidentifiedResponsemodelAPI Workshop on RP2T – Tension Leg Platforms – September 200744
Minimum Deck Clearance CriteriaApplies to deck structure thatis not intended to be immersedRecommended criteria:z At least 5 ft clearance to main steel in extreme (100-yr return period)conditionszzZero or greater clearance in survival (1000-yr minimum return period)conditionsLocal wave effects in these conditions can be dealt with by localstrength designIf the designer chooses to allow and design for wave impact, the entire TLPsystem (including deck, hull, tendons and foundations) should be designedfor the anticipated local and global wave forces and resulting responsesAPI Workshop on RP2T – Tension Leg Platforms – September 200745
Minimum Tendon Tension CriteriaObjective is to prevent unrestrained motions which maylead to tendon disconnect or excessive loads in thestructure or tendon systemRecommended criteria:z For Safety Categories A and B, minimum tendontension in at least 1 tendon per corner shouldremain non-negativezFor Safety Category S, either– minimum tension in at least 3 corner groups of tendons must maintainnon-negative tension in the 1000-yr return period response environment,or– a comprehensive coupled analysis of the tendon system performanceunder loss of tension must be performed to demonstrate proper reengagement of the bottom connector with the foundation receptacle andadequate robustness against subsequent snatch loadingAPI Workshop on RP2T – Tension Leg Platforms – September 200746
Single Event Fatigue CheckComponents that are susceptible to low cycle/high stress fatigue should beanalyzed to assess damage accumulation during rare extreme events that maybe of extended durationRefer to Section 9 for guidanceon single event fatigue analysisfor tendon componentsAPI Workshop on RP2T – Tension Leg Platforms – September 200747

FireEye's Endpoint Security Policy API provides a rich API to allow users to explore functions within the API. The Policy API Tool allows users to add remove and list policy exceptions quickly as well as list create policies for the tool. Overview To get started with the API you will need to create an API user or API Admin to access the API.
