United Arab Emirates-based rig builder Lamprell was awarded an approximately USD-365-million contract to supply Abu Dhabi National Oil Company's drilling division National Drilling Company with two Super 116E, high-specification jackup rigs. The rigs will be constructed at a Lamprell facility in Hamriyah, UAE, and are expected to be delivered by the fourth quarter of 2016 and second quarter of 2017, respectively.
Occidental Petroleum has agreed to participate in a 2-year, USD 500 million exploration project in Abu Dhabi. Occidental will work with the state-owned Abu Dhabi National Oil Company (ADNOC) to explore for oil in the Hail and Ghasha offshore fields in the Arabian Gulf. The scope of work covers 3D seismic surveys, drilling of appraisal wells, and engineering studies for the fields' development. ADNOC is the operator of the venture with 70% interest; Occidental holds 30% interest.
Petrofac was awarded an approximately USD 900 million engineering and procurement contract by Petroleum Development Oman. Under the terms of the 4½-year contract, the company will provide reimbursable detailed engineering, construction, and commissioning support services for the Yibal Khuff project, 350 km southwest of Muscat.
Petro-king Oilfield Technology has been awarded multiple contracts by Sinopec Northern China and Beijing Jiuzun Energy Technology. The combined work is estimated to be worth as much as USD 7.7 million. The company will provide multistage fracturing packers and services for 36 tight gas wells in the Ordos Basin and fracturing services for 12 coalbed methane wells in the Sichuan Basin in China.
Seabed Geosolutions signed an agreement with Abu Dhabi National Oil Co. to conduct a shallow-water seabed survey of the Ghasha-Butini field, offshore the United Arab Emirates. The contract is worth USD 125 million. The company is also preparing for an ocean bottom cable survey in the Asia Pacific region, valued at approximately USD 55 million, which is expected to end in the fourth quarter of the year.
Petsec Energy has completed the acquisition of the participating interests of Mitsui E&P Middle East (8.5%) and AWE (21.25 %) in Block 7 of the Al Barqa permit in Yemen. The block is an onshore exploration permit covering 5000 km2 located approximately 340 km east of Sanaa, the capital. It contains the Al Meashar oil discovery and an inventory of leads and prospects with significant oil potential as defined by 2D and 3D seismic surveys. Oil Search (34%) remains the operator of the block, with the other interests held by Petsec Energy Yemen (29.75%),
Nigel McKim, SPE, has been appointed nonexecutive director of the board for MX Oil. He was most recently the chief operations officer of Nobel Upstream, responsible for building a portfolio of assets in Texas, the UK, and Azerbaijan. McKim started his career as a reservoir engineer at Shell in Oman and has several years of experience in field development planning and production. He was the West Africa asset manager at Vitol Services, director of predevelopment at Hess Services, and subsurface manager for business development activities and the Liverpool Bay project at BHP Billiton. McKim holds a BSc in civil engineering from the University of Bristol and an MSc in petroleum engineering from Imperial College London.
In 1993, Richard D’Souza (Fellow), the principal author and his co-authors presented a landmark paper reviewing the Semisubmersible Floating Production System (FPS) technology at the SNAME centennial meeting in New York. (D’Souza et al., 1993a). The paper captured the twenty year progression of the FPS beginning with the Argyll field in the UK Sector of the North Sea in 80 meters of water that was converted from a semisubmersible Mobile Offshore Drilling Unit (MODU) and began producing in 1975. During this period about twenty five FPSs were installed, primarily in the North Sea and Brazil. Most were converted from semisubmersible MODUs. The deepest was in 625 m, the largest displacing 45,000 mt and the maximum oil rate was 70,000 bopd.
Over forty FPSs have been installed since then, most of which are purpose built platforms. The technology has expanded to a maximum water depth of 2400 m, displacements exceeding 150,000 mt and production rates of 300,000 boepd. The inherent versatility and flexibility of the FPS to adapt to a wide range of water depths, payloads, metocean conditions and future expansion, has resulted in the FPS superseding the Tension Leg Platform (TLP) and the Spar platform as the most widely used floating production platform after the Floating Production Storage and Offloading (FPSO) platform. Its field development applications range from marginal reservoirs to giant deepwater oil and gas fields across the globe.
This paper, authored by Richard D’Souza with a new team of co-authors, is a sequel to the 1993 paper and is intended as a historical and technical archive of the evolution of the FPS technology in the ensuing twenty five years. It highlights the importance of the Naval Architect and Ocean Engineer whose role has evolved from a peripheral to a major player in the design, fabrication and installation of the FPS. This paper has two objectives. One is to inform Operators and Contractors engaged in developing deepwater fields by providing a historical overview of lessons learned and technology evolution of the FPS. The other is to inspire graduate and post graduate Naval Architects and Ocean Engineers to consider a career in the offshore industry where they will have an impactful role in shaping the future of deepwater floating production platforms.
