Chance updates Gulf database
August 30, 1999
The Gulf of Mexico is a maze of platforms, wellheads, pipelines, and other obstacles. Accurate information is essential to successful offshore positioning.
John E. Chance & Associates has recently updated its in-house Gulf of Mexico database, which tracks the location of structures and potential hazards. Unique in the industry, the software is useful to Chance personnel to work with clients in planning projects and assuring a safer offshore operation. Chance has incorporated over 40 years of survey service to the Gulf of Mexico into this database, along with Continental Shelf lease information, shipwrecks, block boundary polygons, pipelines, and shipping fairways. With daily updates, this information comes from in-house fieldwork and additional sources such as the U.S. Army Corps of Engineers and the Minerals Management Service. Manmade and natural reefs are now also indicated within the database.
The database is particularly useful for Chance surveyors to assist clients in planning pipeline routes and in moving and anchoring rigs and barges. It has also proven important in providing information for base map development.
Recently a few new features have been added for more ease in the planning stages of route selection. The attributes of existing pipelines such as product, status, permit approval date, and segment number are available. Also valuable is the ability to further customize the site area view by overlaying navigation charts, bathymetric data, and client CAD files.
In addition to the comprehensive Gulf of Mexico database, a similar database for Trinidad and Venezuela has recently been developed.
