The facility complements the existing 7,500 sq ft Hot Tap and Stopple Plugging Service Centre by adding a stand-alone maintenance capability aimed primarily at the ILI regional market.
In addition to serving as our Middle East hub for inline inspection, the centre also extends our hot tap and plugging equipment maintenance capacity, with sizes up to 36 inches for hot tapping and 24 inches for Stopple plugging operations," he adds.
In addition to MSD and Haberberger, Tarlton's partners on the project arc Black & Veatch, KAI Design & Build and TD Williamson, which installed the STOPPLE
The repair plan developed permitted the removal of the pipeline section containing the blockage and the pigging tool well within the stopple
tees, thereby stopping the flow of the liquid product before the operation.
TDW was retained to use the Stopple Train intervention method for a number of reasons.
Prior to the operation, TDW custom-built a fully-rated 1480 psi (102 bar) Stopple Train system at its manufacturing plant in Tulsa, Oklahoma.
In the second phase of the project, Global Divers and Contractors installed a series of three individual pipeline connectors (a 20 x 12-inch hot tap, a 20-inch line stopple
, and a 20-inch end connector) to reroute one end of the 20-inch line to the pump station platform.

In addition to serving as our Middle East hub for inline inspection, the center also extends our hot tap and plugging equipment maintenance capacity, with sizes up to 36 inches for hot tapping and 24 inches for Stopple
plugging operations," he added.
INTERVENTION FOR KTO Earlier, TDW announced that it has successfully performed its first pipeline pressure isolation operation using Stopple
plugging technology for KazTransOil (KTO).
Following completion of the welding phase in June 2010, TDW began preparing for the Stopple
plugging operation in August.
A 14-inch line was isolated with the traditional STOPPEE plugging method, while a 24-inch line and a 32-inch line were isolated with TDW's folding STOPPLE
Though it represents an innovative new method to achieve double block and bleed, the patent-pending STOPPLE
Train plugging system is based on proven technology developed by TDW in the 1950s as a means to temporarily block sections of active piping systems.
Conversion of the land-based Grouted Tee[R] to SSGT in the JIP was performed on a 24-inch stopple
branch off a 24-inch pipeline with ANSI CLASS 900 flange connection for shallow water diver depth operations (i.
These tools, such as the Lineboar Piggable Valve[TM], allow repair and maintenance to take place without blowing down, evacuating or depressurizing the onshore pipeline, and without welding on or cutting a hole into the line using hot-taps or stopples
