  • top tensioned riser system design for the fhsb dry tree semisubmersible Platforms
    ASME 2013 32nd International Conference on Ocean Offshore and Arctic Engineering, 2013
    Co-Authors: Jim Yu, Alaa M Mansour, Alan Yu, Ricardo Zuccolo
    Abstract:

    The dry tree production and drilling Top Tensioned Riser (TTR) systems have been extensively used with Tension Leg Platforms (TLPs) and Spar floaters in deepwater applications. However, the large heave response of the conventional Semisubmersible floaters makes this type of Platforms not suitable for dry tree applications largely due to the ultra-long stroke tensioner that would be required in this case.The Free Hanging Solid Ballast (FHSB) Semi is an innovative new semisubmersible design that is suitable for dry tree applications due to its low heave response that is comparable to that offered by Spar floaters. The new design resembles the conventional Semisubmersibles with an added free-hanging solid ballast tank placed deep below the keel of the Semisubmersible hull and connected to the hull through four groups of chains. The Solid Ballast Tank (SBT) acts as a motion damper that significantly improves the heave motion response.In this paper, the design of the dry tree TTR system for the FHSB Semi is presented. The typical GoM’s drilling and production conditions are used in designing the TTR system including the tensioning system and the interface between the SBT and the riser keel joint. The feasibility and performance of the designed TTR system are demonstrated through static and dynamic TTR analyses.Copyright © 2013 by ASME

  • The Hermite Moment Model for Highly Skewed Response With Application to Tension Leg Platforms
    Journal of Offshore Mechanics and Arctic Engineering, 2010
    Co-Authors: Myoungkeun Choi, Bert Sweetman
    Abstract:

    A new addition to the statistical Hermite moment model of extremes is introduced for use on processes with high skewness and near-Gaussian kurtosis. The monotone limits of the existing model are expressed as ellipses in response moment space and a new methodology is introduced that combines hardening and softening models to overcome these limits. The result is that any fractile of a distribution described by its first four statistical moments can be transformed to or from the Gaussian. An example application to a tension leg platform is presented.

  • RESPONSE OF TENSION LEG PLATFORM TO WAVE DRIFT FORCES
    All Days, 1992
    Co-Authors: Ahsan Kareem
    Abstract:

    The wave drift forces on tension leg Platforms (TLP) are contributed by second-order potential and viscous wave load effects, the fluctuations in wave surface elevation and the influence of platform displaced position on the wave excitation. These forces are expressed in terms of in-phase study, computationally efficient time domain and frequency domain based schemes are developed to evaluate the TLP response to drift forces. These schemes retain the statistical relationship that exists among these drift forces which is important for the combined response analysis. A parameter study is conducted to delineate the relative significance of different drift forces for several representative sea-states.

  • Response Statistics of Tension Leg Platforms Under Wind Loads
    1992
    Co-Authors: Jun Zhao, Ahsan Kareem
    Abstract:

    This paper presents the direct integration method and Kac-Siegert technique to solve the first four cumulants in the general quadratic systems, and proposes the splitting technique to deal with the fluid-structure interaction problem. The response statistics of tension leg Platforms (TLPs) subjected to wind loads, are solved up to the fourth-order cumulant (kurtosis). Based on the first four cumulants, various methods for the non-Gaussian distribution have been compared with the simulation result.
