Spars are floating vertical cylinders that support production decks above storm waves. The first purpose-built semisubmersible production platform was for the Balmoral field in the North Sea in 1986. 2.5. As of this writing Petronius is the world's tallest freestanding structure (it is about 300 ft or 91 m taller than the CN Tower in Toronto) [Wikipedia encyclopedia]. In the late 1960s, companies initiated research and design for these semisubmersible, multihull tubular structures and ships that would remain relatively stable in rough seas. However, unlike its predecessor, a compliant tower is designed to flex with the forces of waves, wind and current. Figure 12.4. In: Structure of Typical American Oil Fields: SP 14, American Assoc. The rig consists of narrow, flexible (compliant) towers and a piled foundation supporting a conventional deck for drilling and production operations. The water depth at the intended location dictates platform height (Figure 3.2). The compliant tower offers a number of advantages as it provides a stable, conventional, cost effective base for offshore drilling and production operations using dry trees, and fixed or steel catenary risers. 3.3.1 Compliant Tower A CT consists of a narrow, flexible tower and a piled foundation that can support a conventional deck for drilling and production operations. The article reports on the oil production of the first compliant piled tower of Cabinda Gulf Oil Co., Ltd., a subsidiary of Chevron, in Angola. The Baldpate compliant tower, owned by Amerada Hess Corporation as operator, and Oryx Energy Company as 50% joint interest owner, installed in Garden Banks 260 in the Gulf of Mexico, is the first free-standing, non-guyed compliant tower. The CT design is more flexible (hence the name) than conventional land structures to cope better with sea forces—it can deflect (sway) in excess of 2% of height. The design achieves this by relying on a narrower tower of steel and concrete. The Chevron Petronius platform (a deep water CT) is a crude oil and natural gas platform in the Gulf of Mexico, which stands 2,000 ft above the ocean floor and the structure is partially supported by buoyancy. Lena was installed in 1983 and is near the end of its 35-year life, generating about $18 million in gross revenue in 2016.
