INTRODUCTION
To determine the effect of the subcellar deck areas of the proposed Viosca Knoll 900 A Platform structural modifications on the integrity of the platform it was necessary to perform an ultimate strength analysis in accordance with Supplement 1, API RP2A Section 17. ...
To demonstrate the adequate strength and stability of the platform to survive the ultimate strength loading criteria a linear global ultimate strength analysis was performed. The ultimate strength loading criteria for an assessment criteria level of L-1 was determined from Sections 17. ... 3 the ultimate strength of undamaged members, joints and piles was established using the formulas of Sections 3, 4, 6 and 7 with all safety factors removed, or a safety factor of 1. ... The analysis was performed using Engineering Dynamics Inc. ...
PROCEDURE
JACKET AND MEMBER CHECKS
The ultimate strength analysis criteria given in Table 17. ... 75) was applied for the ultimate strength wave load combinations to approximate the removal of the allowable stress safety factors for the combined axial and bending member checks. ... 00 indicates that they may be exceeding their ultimate strength. To determine the ultimate strength unity check ratio of these specific members the actual stresses were compared to the ultimate strength allowable stresses calculated in accordance with Section 17.
