Aug. 2012 - McDermott International announced that one of its subsidiaries received a contract by Williams Partners for transportation and installation services for a spar hull in the Gulf of Mexico. The company will transport and install the Gulfstar FPS GS-1 spar hull and moorings. The spar platform will be moored on the Tubular Bells development, situated about 150 miles (241 kilometers) offshore, on Mississippi Canyon Block 683 and 726 in a water depth of 4,200 feet (1,280 meters). McDermott's DB50 vessel will install the moorings before transporting the classic-design spar hull to the installation site where it will be upended and ballasted before installing a temporary work deck. The offshore campaign is expected to begin in the third quarter of 2013.

May. 2012 - ClampOn will supply multiple subsea acoustic sand vibration detectors and PIG detectors for the Tubular Bells project. The development is slated for production in 4Q 2014.

Feb. 2012 - Hess Corporation has awarded Technip a lump sum contract for the development of the Tubular Bells field in the GOM. The contract covers the design, engineering, fabrication and subsea installation of more than 28 miles (45 kilometers) of flowlines, steel catenary risers, pipeline end terminations, piles and structures. Offshore installation is scheduled for completion during the first half of 2013.

Jan. 2012 - Wood Group's Alliance Engineering received a detailed engineering and design contract of the topside facilities and deck, for Williams Partners' Gulfstar FPS spar production platform. The platform, for installation in Mississippi Canyon Block 768, will produce oil and gas from the Tubular Bells field. The Gulfstar spar platform will be located in 4,300 feet (1,311 meters) of water and designed to process 60,000 bopd and 200 MMcf/d. The single-lift topsides will have three deck levels and include processing equipment, seawater injection equipment, utilities, an accommodation building with helideck, and pumping and compression equipment to export the treated oil and gas through departing pipelines. The completed deck will weigh approximately 7,000 short tons. Initial production is scheduled to commence in 2014.

Oct. 2011 - Williams Partners have signed several agreements with Hess and Chevron to provide production handling, export pipeline, oil and gas gathering and gas processing services in the Tubular Bells field development. As previously reported in May 2011, Hess will use Williams Partners' proprietary floating production system Gulfstar FPS. The vessel will be capable of serving as a central host facility for other deepwater prospects in the area. Williams Partners will design, construct and install its Gulfstar FPS with a capacity of 60,000 bopd, up to 200 MMcf/d, and the capability to provide seawater injection services. The facility is a spar-based FPS that will utilize traditional three-level topsides mated to a classic spar hull. Gulfstar FPS is scheduled for delivery in 30 months. The Tubular Bells field is located on Mississippi Canyon Blocks 633 and 726 in the deepwater Gulf of Mexico. Hess operates the development, holding a 42.86 percent interest.

Oct. 2011 - Hess will begin developing the deepwater oil and gas field, Tubular Bells, in the Gulf of Mexico. The development plan calls for three subsea production wells and two water injection wells from two subsea drill centers, which will be connected to a third-party owned spar production facility (this spar facility is the first of its kind constructed entirely in the United States). Drilling should begin in 2012, and initial production is slated for 2014. Hess states that annual gross production should peak at about 40,000-45,000 boepd. Total recoverable resources for Tubular Bells are estimated at more than 120 MMbbl of oil equivalent. Hess expects to spend about US $2.3 billion for development, with additional commitments for production handling, export pipeline, and oil and gas gathering and processing services. Hess holds a 57.14 percent operating interest in the field, and Chevron holds the remaining 42.86 percent interest.

May. 2011 - Hess Corporation awarded Williams Partners a letter to provide production handling services at Tubular Bells field development in the Gulf of Mexico. Hess will utilize the company's proprietary floating-production system, Gulfstar FPS, which may serve as a central host for other operations in the deepwater area. Williams Partners will design, construct and install its Gulfstar FPS with a capacity of 60,000 bopd of oil and up to 200 MMcf/d of natural gas, and have the capability to provide seawater injection services. The facility is a spar-based floating production system that utilizes traditional three-level topsides mated to a classic spar hull. This standard design approach will allow customers to reduce their cycle time from discovery to first oil, stated Williams Partners. The company has issued a letter of award to Gulf Island Fabrication Inc., through its subsidiary Gulf Marine Fabricators, to construct the hull portion of the Gulfstar FPS. Williams Partners expects to select and award the topsides portion of the Gulfstar FPS to a Gulf Coast fabricator, making this the first spar-based floating production system to be built entirely in the U.S. Gulf Coast area. The Tubular Bells field is located on Mississippi Canyon Blocks 633 and 726 in the deepwater Gulf of Mexico. Hess operates the development, holding a 40% interest.

May. 2009 - AMEC has been appointed by BP to provide engineering services for the Tubular Bells and Kodiak discoveries in deepwater Gulf of Mexico. AMEC is evaluating several potential development options for selection of a preferred project option to advance into front-end engineering design (FEED), which provides an opportunity to influence overall cost, weight, schedule and facility performance at the early stages of the project.

Jan. 2007 - John Hess, Hess's CEO said that there has been successful appraisal drilling at the Tubular Bells prospect, on Mississippi Canyon Blocks 683 and 726, in which Hess has a 20% interest, has been very encouraging. Appraisal drilling at both these discoveries will continue in 2007.

Oct. 2003 - Amerada Hess has made a new deepwater oil discovery at the Tubular Bells Prospect located in Mississippi Canyon Block 725. The block is located 135 miles Southeast of New Orleans.
