Filed:

May 12, 1998

Appl. No.:

09/076580

Inventors:

John R. Brewer - Katy TX
David J. Brown - Houston TX
Peter H. Brücher - Berllin, DE

Assignee:

Stone Webster Process Technology, Inc. - Houston TX

International Classification:

F28D 700

US Classification:

422200, 422196, 422197, 422198, 422204, 196110, 196116

Abstract:

The present invention provides a furnace and process that relies on a multiplicity of radiant heating tubes, each in the form of a U-shaped coil, that are mounted within a furnace firebox such that an inlet leg of any one of the plural tubes is immediately adjacent and spaced apart from an outlet leg of another one of the plural tubes within the firebox of a thermal cracking furnace. This spacial pairing of an inlet leg of one tube with an outlet leg of another tube of the plural radiant heating tubes of the cracking furnace maximizes utilization of the available radiant heat within the firebox of a thermal cracking furnace while reducing the likelihood of localized hot spotting that could produce coke-tar plugging of a tube.

International Classification:

G06F015/16
G06F017/60

US Classification:

709/206000, 705/026000

Abstract:

A method and system are provided whereby a request for proposals for professional services may be posted on a computer network, e.g., the internet, and professional service providers respond with proposals for their respective services. A user enters a proposal for professional services on a web-site of the computer network. The proposal is received by a first service provider at the site, who responds with a first proposal. The proposal is also received by at least one additional service provider at the site, who responds with a second proposal. The user receives the first and second proposals, and any additional proposals, at the site. The user then evaluates the proposals and selects one of the proposals.

Appl. No.:

5/817159

Inventors:

John H. Brewer - Irvine CA
Peter G. Harwood - Mission Viejo CA

Assignee:

Compagnie Francaise des Petroles - Paris

International Classification:

E21B 33035

US Classification:

166359

Abstract:

A termination means for a plurality of riser pipes at a floating platform including a termination member for supporting said plurality of riser pipes, said termination member being supported and suspended by constant tension means on said platform. The plurality of riser pipes include a central riser pipe and satellite riser pipes arranged around said central riser pipe. Each of the satellite riser pipes extend through the termination member and are supported from said termination member by fluid pressure actuated tension compensator means which serve to tension each of the riser pipes. The termination means is adapted to both rigid and flexible riser pipes.

Appl. No.:

9/375096

Inventors:

Peter Brucher - Oranienburg, DE
David J. Brown - Houston TX
John R. Brewer - Katy TX

Assignee:

Borsig GmbH - Berlin

International Classification:

F28F 902

US Classification:

165158

Abstract:

A heat exchanger with a connection that connects an uncooled pipe to several cooled pipes. The connection (3) has a cylindrical intake section that communicates with the uncooled pipe (2) and merges into an outward-tapering terminating section (9. The terminating section encloses several gas-conveying channels. Each gas-conveying channel extends out of the intake section coaxial to one of the cooled pipes (4). The gas-conveying channels (10) branch out in the shape of a star from the connection's intake section (8). The cooled pipes are inserted into a base (6) and arrayed along a segment of a circle. The gas-conveying channels are arrayed along the same segment.

International Classification:

E02B 1700
B63B 3544

US Classification:

405224

Abstract:

A method of conducting offshore well operations including exploration drilling and production from a single floatable platform which is converted from semisubmersible exploration mode to tension leg production mode at a well site. A method of conversion of platform from catenary mooring mode in which exploration and drilling operations are conducted from the platform in semisubmersible mode at the well site to establish production capabilities and upon determining the well site should be produced to tension leg mode for production including the steps of, preparing to conduct production operations in tension leg mode by lowering and setting anchor pile guide means carried by the platform at selected anchor locations, shifting the platform in semisubmersible mode for drilling at each anchor pile guide means, setting permanent anchor pile members in the sea floor at the anchor pile guide means, connecting a tension leg means to the anchor pile members and to said platform, initially tensioning said tension leg means to a selected tension, then releasing said platform from said catenary mooring mode, and further tensioning said tension leg means for operation of said platform in tension leg production mode. A mobile offshore marine platform for conducting exploratory drilling operations in semisubmersible catenary anchor mode and for conducting production activities in tension leg production mode wherein conversion means includes anchor means carried by the platform, means on the platform for installing the anchors while the platform is in catenary anchor mode and tension leg means for interconnecting the anchor means and the platform.
