In 2005 he developed a new floating drilling semi-submersible named TDS 2000. The main advantage of this design is that it can be fabricated efficiently at a quay-side fabrication yard at a low cost. This advantage became obvious in 2006 when all shipyards are busy and their fabricating price increase substantially.
In 2007, he led GustoMSC to design and market the floating drilling semi-submersibles in a turnkey manner. The effort brought in a major construction contract for its parent company, SBM Offshore, to build three drilling semi-submersibles for the Brazilians for operation in water depth ranging from 2,000 to 2,800 meter. These floating semis are currently under construction in Abu Dhabi. The contract included engineering, procurement of equipments, construction, commissioning all equipment and final sea trials. The total contract value exceeds US$ 1.2 billion.
In 2003, after joining SBM, he developed floating semi-submersible for oil and gas production. The main idea was for the hull to be fabricated at a different site than that for the top side. They are then brought together for quay side integration. This would avoid the high cost and frequent delayed associated with offshore installation. In 2005, the design was sold to Independence and resulting in a design, procurement and construction contract of more than US$200 million. Then, Dr. Bui led the efforts at GustoMSC that completed the engineering for the Independent Hub, a floating gas production facility in the Gulf of Mexico in water depth of 8,000 feet, which holds the world record depth for production platforms to date.
In 1999, Dr Bui developed the floating drilling semi submersible named ENSCO 7500. It was built in Orange, Texas in a record time and low cost. The design was so successful that four more semi’s were built over the years.
In 1998 Dr. Bui developed the drilling barges contracted for Exxon in Lake Maracaibo, Venezuela. His company provided all the engineering as well as shipyard construction support for the projects. Three barges were built in less than a year.
In 1997, He formed Ocean Design Associates. The company provided a full range of engineering service to the offshore oil and gas sector. Among the clients include Exxon Mobile, Chevron Texaco, Shell, BP. The company was sold to SBM Offshore, an oil and gas service company based in the Netherland. The name was changed to GustoMSC after the sale. Per the sales contract, Dr Bui stayed on as president to manage GustoMSC for 5 more years.
In 1990, he developed high energy particle accelerator and super conducting magnets at the Super Conducting Super Collider in Dallas, Texas.
In 1980, while at Seco Forex, Schlumberger, he developed the floating semi SEDCO 600. The vessel was built on the beach at Promet Shipyard in Singapore. The completed vessel was launched using the old fashion skid way, thus saving the expensive cost of using dry dock. Three vessels were built simultaneously next to each other.
Dr. Bui was an adjunct professor at the University of Oklahoma Civil Engineering Department in 2005 and 2006.
Dr Bui received his Master of Science and Ph. D. from University of California at Berkeley, in structural engineering and structural mechanics, in 1975 and 1980.
