A bracing structure is provided in the form of an elongated bracing member having first and second ends, the first end having a pile sleeve for engaging the bottom, the second end having a doubler plate or the like for engaging a caisson above the water line. A pulley may be provided on the caisson above the water line, in the vicinity of where the doubler plate is to be mounted on the caisson. A cable having first and second ends is provided, the first end affixed to the bracing member in the vicinity of the doubler plate, the second end engaging the tugger or winch. In use, the tugger draws the cable so as to urge the doubler plate to the caisson above the water line in the vicinity of the installation area.

A system for removal of Hydrogen Sulfide (HS) and/or Carbon Dioxide (CO) from natural gas via absorption and disassociation utilizing a sea water contact system. In the preferred embodiment of the present invention, a series of counter current scrubber stages is provided, each configured to remove via absorption/disassociation a portion of the impurities, each stage having less pressure than the predecessor, each stage redirecting the purified gas to the preceding stage, until the contaminant level in the hydrocarbon gas stream has been reduced to an acceptable level. The hydrogen sulfide/carbon dioxide contaminants are thereby sequestered in the sea water utilized in the scrubber, which sea water may be further processed and/or re-introduced into the deep of a body of water, where the contaminants will remain isolated for hundreds of years. The present invention further contemplates and energy recovery system for greatly enhancing the efficiency of the system. Accordingly, the present invention provides an efficient and cost effective method for the purification of natural gas on an offshore platform.

A heat exchanger system suitable for facilitating the economical cooling of hot fluids in the vicinity of a body of water. The preferred embodiment of the present invention contemplates a vertical, or combination vertical and horizontal thermosyphonic, passive, heat exchanger column situated in a body of water and enveloped by a caisson or the like, and configured to facilitate, through percolation, enhanced circulation of seawater therethrough and effecting significant cooling of a hot, hydrocarbon well stream, or other hot fluid in the vicinity of a body of water. A vertically situated bundle of tubes forms the heat exchanger, which may include a system of staggered baffles to direct the flow of cooling seawater to effect even temperature distribution throughout the tube bundle. The present system further teaches a system for cooling high pressure, hot fluids as may be found in a deep hydrocarbon reserve offshore, utilizing a the vertical heat exchange column of the present invention. Upon passing through the system, a gaseous fluid stream, significantly cooled, should experience a commensurate pressure reduction and allow the use of conventional pipeline materials.
