CZMA Consistency Revisited: A Mechanism to Mitigate OCS Impacts?
With the Coastal Zone Management Act (CZMA) recently reauthorized for five years and recent legal developments regarding consistency, this is the ideal time to revisit the question: are...
The DST Well: Its Importance and Lessons Learned
A Deep Stratigraphic Test (DST) well is a unique source of stratigraphic information; and provides critical data on drilling conditions, logistics, materials; and subsurface conditions...
Oil Rigs: Biology, Mariculture, Drilling Muds, Rigs-to-Reefs
Oil platforms in the Gulf of Mexico and Santa Barbara Channel provide hard substrates, diverse habitats and excellent breeding grounds from the sea floor through the splash zone. As a...
Major Issues Associated with Offshore Petroleum Development
Santa Barbara County has been confronted with a host of significant issues related to offshore oil and gas development, including: the extent and limitations of local control over development;...
Bulkhead Instability in Soft Soil
This paper presents a case study involving the severe disturbance of the subsurface soils in front of an existing bulkhead caused by the berthing of a jack-up type, offshore drilling vessel....
Directional Drilling Cuts Force Main Costs
Design of Drilled Piers Subjected to High Overturning Moments
The results are presented of a research study directed at improving the state-of-practice, and resulting foundation economy, in the design of laterally loaded drilled pier foundations...
Drilling Unit Approval and Sea Ice, Alaska OCS
This paper describes types of ice conditions that have been, or could be, encountered while conducting Alaska Outer Continental Shelf (OCS) operations. The types of ice monitoring programs,...
Repair Welding of Arctic Offshore Structures and Vessels
This paper describes the welding procedure development for repair or field modifications of offshore drilling structures and vessels made with several different steel grades produced for...
Waterfront Electric Cone Penetration Testing
Offshore deployment methods developed for use by the oil industry were combined with less expensive nearshore drill barge technology. This resulted in the successful completion of cone...
Grand Canyon Water Line by Directional Drilling
The South Rim Village at Grand Canyon National Park obtains its water supply from a point called Roaring Springs which is located approximately 15 miles across the Canyon on the North...
Wind Loads on Offshore Drilling Platforms
Icebergs Used as Oil Drilling Base
A Contractor Looks at Slope Protection for Arctic Offshore Artificial Islands
Some thirty artificial gravel islands for oil and gas drilling/production have been built in the Beaufort Sea since early 70's. Protection of slopes of the islands and causeways...
Arctic Offshore Site Investigations
The continuing search for new petroleum sources has led to increased exploration activity in the arctic offshore regions of Alaska. The general approach to site investigations has been...
A Critique of Arctic Marine Site Investigation Techniques
Arctic marine site investigations have evolved from the need by oil companies to operate in offshore areas beyond the ice shear zone. An overview of the site investigation organization...
Ice Loads on Structures With Compound Slopes
Many of the offshore drilling structures proposed for use in the Arctic have sides with multiple slopes. Sloping walls are used at the waterline to cause the ice sheet to fail in bending...
Logistics for Structures Sealifted to the Arctic
Sohio has successfully pioneered the development of the Prudhoe Bay reservoir by sealifting prebuilt oil processing facilities from the lower 48 states. The experience thus gained is being...
Design of an Icebreaking Offshore Supply Vessel
There are two basic scenarios for icebreaking support vessels. The first is the delivery of drilling fluids and supplies to drilling units and other development operations. The second...
Tanker Mooring/Loading Systems for Northern Offshore Arctic Regions
Transportation of crude oil in arctic areas via shuttle tankers can prove to be a viable alternative to a pipeline system. The shuttle tanker system will require offshore terminals equipped...
