Offshore Drilling Activity Increases Demand For Risers

June 30, 1997

These syntactic foam risers are rated at 4,500 ft water depths (Fig. 2). Cameron's facilities in Texas, Scotland, and Norway have delivered more than 2.5 miles of risers in the first quarter of 1997, and will be shipping 5.5 miles of risers by the end of the year. The 21-in., 60-ft long Cameron RF flanged risers shown in Fig. 1 have five integral well-control lines: 1. One 15,000 psi choke line, 5-in. OD by 3-in. ID 2. One 15,000 psi kill line, 5-in. OD by 3-in. ID 3. One 5,000 psi

These 60-ft flanged risers contain integral auxiliary lines which are easily configured (Fig. 1).

Cameron's facilities in Texas, Scotland, and Norway have delivered more than 2.5 miles of risers in the first quarter of 1997, and will be shipping 5.5 miles of risers by the end of the year.

The 21-in., 60-ft long Cameron RF flanged risers shown in Fig. 1 have five integral well-control lines:

1. One 15,000 psi choke line, 5-in. OD by 3-in. ID
2. One 15,000 psi kill line, 5-in. OD by 3-in. ID
3. One 5,000 psi mud-booster line, 5-in. OD by 4-in. ID
4. Two 5,000 psi stainless-steel, dual-hydraulic conduit lines, 1.75-in. OD by 1-in. ID. (cross-sectional view).

Choke and kill lines are used to circulate drilling mud in the event of a kick.

The hydraulic mud-booster line is used as an additional means to circulate mud and cuttings in deep water. The dual-hydraulic lines shown in the cross-sectional view are used to operate the blowout preventer on the ocean floor.

These risers are slated to be used in the North Sea and have no buoyancy modules.

The 21-in., 60-ft long Cameron RF flanged risers in Fig. 2 contain syntactic foam buoyancy modules. They are rated for 4,500 ft water depths. Cameron's RF riser connectors have tension loads rated at 2 million lb.
