Hydrodynamic comparison of a semi-submersible, TLP, and Spar: Numerical study in the South China Sea environment

The South China Sea contains tremendous oil and gas resources in deepwater areas. However, one of the keys for deepwater exploration, the investigation of deepwater floating platforms, is very inadequate. In this paper, the authors studied and compared the hydrodynamics and global motion behaviors of typical deepwater platforms in the South China Sea environment. The hydrodynamic models of three main types of floating platforms, e.g. the Semi-submersible, tension leg platform (TLP), and Truss Spar, which could potentially be utilized in the South China Sea, were established by using the 3-D potential theory. Additionally, some important considerations which significantly influence the hydrodynamics were given. The RAOs in frequency domains as well as global motions in time domains under time-varying wind, random waves, and current in 100-y, 10-y, and 1-y return period environment conditions were predicted, compared, and analyzed. The results indicate that the heave and especially the pitch motion of the TLP are favorable. The heave response of the Truss Spar is perfect and comparable with that of the TLP when the peak period of random waves is low. However, the pitch motion of Truss Spar is extraordinarily larger than that of Semi-submersible and TLP.     

中国南海ASDD深水试验井中的锚泊设计与作业(英文)

Mooring systems play an important role for semi-submersible rigs that drill in deepwater.A detailed analysis was carried out on the mooring of a semi-submersible rig that conducted a trial well drilling at a deepwater location in the South China Sea in 2009.The rig was 30 years old and had a shallow platform with a designed maximum operating water depth of 457 m.Following the mooring analysis,a mooring design was given that requires upgrading of the rig’s original mooring system.The upgrade included several innovations,such as installing eight larger anchors,i.e.replacing the original anchors and inserting an additional 600 m of steel wires with the existing chains.All this was done to enhance the mooring capability of the rig in order for the rig to be held in position to conduct drilling at a water depth of 476 m.The overall duration of the drilling was 50 days and the upgraded mooring system proved to be efficient in achieving the goal of keeping the rig stationary while it was drilling the trial well in the South China Sea.This successful campaign demonstrates that an older semi-submersible rig can take on drilling in deep water after careful design and proper upgrading and modification to the original mooring system.     

深水钻井平台定位系统评估

This paper addresses the need for systematic evaluation of the station keeping systems of deepwater drilling semi-submersibles. Based on the selected drilling semi-submersible configuration, the mooring systems were analyzed and designed for a range of water depths using different mooring line materials. These were steel wire rope, polyester rope and HMPE (high modulus poly ethylene). The mooring analysis was carried out using the advanced fully coupled time domain analysis method in the computer software package HARP. Diffraction analysis was first applied to solve the hydrodynamic properties of the vessel and then the motion equations of the complete dynamic system including the drilling rig, the mooring lines and risers were developed and solved in the time domain. Applying the advanced analysis method, a matrix of mooring systems was developed for operating in water depths of 1 000 m, 1 500 m, and 2 000 m using various mooring materials. The development of mooring systems was conducted in accordance with the commonly adopted mooring design code, API RP 2SK and API RP 2SM. Fresh attempts were then made to comparatively evaluate the mooring system’s characteristics and global performance. Useful results have been obtained in terms of mooring materials, water depths, and key parameters of mooring configurations. The results provide in-depth insight for the design and operation of deepwater mooring systems in the South China Sea environment.     

Floating production platforms and their applications in the development of oil and gas fields in the South China Sea

This paper studies the current available options forfloating production platforms in developing deepwater oil fieldsand the potential development models of future oil and gasexploration in the South China Sea. A detailed review of currentdeepwater platforms worldwide was performed through theexamples of industry projects, and the pros and cons of eachplatform are discussed. Four types of platforms are currently usedfor the deepwater development： tension leg platform, Spar,semi-submersible platform, and the floating production systemoffloading. Among these, the TLP and Spar can be used for dry treeapplications, and have gained popularity in recent years. The drytree application enables the extension of the drilling application forfixed platforms into floating systems, and greatly reduces the costand complexity of the subsea operation. Newly built wet treesemi-submersible production platforms for ultra deepwater are alsogetting their application, mainly due to the much needed payloadfor deepwater making the conversion of the old drillingsemi-submersible platforms impossible. These platforms have beenused in different fields around the world for different environments;each has its own advantages and disadvantages. There are manychallenges with the successful use of these floating platforms. A lotof lessons have been learned and extensive experience accumulatedthrough the many project applications. Key technologies are beingreviewed for the successful use of floating platforms for fielddevelopment, and potential future development needs are beingdiscussed. Some of the technologies and experience of platformapplications can be well used for the development of the SouthChina Sea oil and gas field.
