The traditional method for installing offshore pipelines in relatively shallow water is commonly referred to as the S-lay method because the profile of the pipe as it moves in a horizontal plane from the welding and inspection stations on the lay barge across the stern of the lay barge and on to the ocean floor forms an elongated "S". |

There are three major categories of insulation systems: pipe-in-pipe systems, integrated towed flow line bundles, and non-jacketed systems. The design of all of these systems seeks a balance between the high cost of the insulation, the intended operability of the system, and the acceptable risk level.

One technique for extending the life of a gas pipeline is to coat the inside of the pipe periodically with a corrosion-inhibiting substance (CIS). The coating may be applied as either an aerosol pumped in with the production stream or as a liquid "slug" pushed through the pipe with a pig. The slug treatment provides greater protection. |
