HOUSTON, TEXAS – Bob “Sonny” Fogal, one of the icons in the offshore oil and gas industry, has decided to retire from front-line work as Zentech’s Director of Business Development. Zentech’s President Ramesh Maini noted on August 28th “All the serious players in our industry know Bob and his many accomplishments. He is clearly among the elite in this group.”

Mr. Fogal has spent his entire career in the rig building business, starting with Levingston Shipyard and subsequent work with major designers and builders in the U.S. as well as Singapore, Japan, China, Brazil, India, South Africa, and the Middle East. His official full-time employment began in 1957, although

Bob admits that he was actually working part-time in the shipyard even before then. His earliest assignments included engineering, estimating and QA-QC in the shipyard, followed by equal success in construction, projects, yard management and ultimately sales. This is where his star really started to shine, where Bob discovered his true passion. Ramesh Maini points out that “Since that time, Bob has been heavily involved in the sale and building of over 100 rigs and vessels.”

Throughout his career, Bob has accumulated many awards and accolades for his contributions to the industry. He has held memberships in IADC, MTS, SNAME, SPE and the NOMADS.

When asked about his future plans, Bob was noncommittal about his next adventure, although he wants to spend more time with his wife at their home in Alabama, and also with his children, grand- and great-grandchildren.

Excerpt from article by Drilling Editor Nina M. Rach

Engineers at Houston-based Zentech Inc. have created two designs for a new type of multi-service, self- propelled jack up vessel with removable drilling apparatus, capable of working in water up to 210 ft deep. A removable rig package enables such a vessel to work in construction, diving support, pipe-laying, or as a tender-assist unit. Typical Gulf Coast lift boats have increased in size over the years but are subject to storms and poor maneuverability. One design was produced, pursuant to an October 2000 agreement with Covington, La.- based Oases Offshore Inc. A schematic of this design on Oases Offshore’s website shows a cantilevered rig on a rectangular deck with three legs, three cranes and 18,000 ft of deck space. According to a June 2003 press release from the Yantai Raffles shipyard in China, the yard has a contract to build one of the Zentech/Oases jack ups, executed with a Nigeria-based representative of Oases Offshore.

Zentech’s second design, the Z-210, is designed to mobile offshore drilling unit (MODU) specifications and follows MODU survivability rules. Zentech says the four, 1,500 hp, fully azimuthing thrusters will provide better maneuverability than a typical lift boat. The vessel has 1,814 tonnes variable load capacity, including 907 tonnes on the 20,000 sq ft open deck. The Z-210 has four triangular legs, each 3211⁄2 ft long.

Zentech also has new designs for standard jack ups, the Zentech R-450 and Zentech Z-636, utilizing the Zenlock leg locking system.
