Russian section of Nord Stream gas line in place
Is simultaneously laying sections of the line in the Gulf of Finland as well.Construction of landfall facilities for both pipelines has also been completed on the shore at Portovaya Bay near Vyborg.
The first Nord Stream pipeline has been completed and should enter service during 4Q 2011.
Onshore facilities 1.5 km (0.9 mi) from the shoreline include pig traps, isolation, and emergency shutdown valves. This equipment has been installed – assembly is under way of telemetry and automation systems.
Later in the summer, gas-in equipment will be added for the commissioning stage.

Two of 8 emergency diesel generators were inoperable on April 27 and a third was shut down on April 28. 3. On April 27, the Unit 3 "B" Main Steam Isolation Valve unexpectedly indicated "intermediate" –which may mean there was an electronic indicator
Compromises TransCanada has agreed to with US regulators include narrower spacing of isolation valves, which allow the operator to confine damage and leakage from a section of pipe in the event of an emergency. The valves will be placed more frequently
These parts, known as main steam isolation valves, block radioactive coolant in boiling water reactors as it leaves the reactor core on its way to the turbine building. During an emergency like an earthquake, this prevents a radioactive release into

Hydraulic Partial Stroke and Diagnostics on Emergency Shutdown Valves
The operating integrity of the SIS usually depends on the final control element (an isolation valve). These valves typically remain in one position until needed. In most cases they will never be used to provide emergency isolation which means they can become stuck due to component failure, corrosion or erosion. If the isolation valve does not operate when needed, the process may not be able to stop which presents a catastrophic environment for equipment and personnel.
As we mentioned last week , full stroke testing must be done at certain intervals to uncover issues that partial stroke testing cannot. Increasing this time interval helps to defer some of issues Shailesh highlights, including:
The process must be shut down or the isolation valve must be bypassed to allow for a full stroke test which is time consuming and costly. Mechanical partial stroke testing requires the installation of a travel limiting device and if the device is not removed the isolation valve will not be able to fully stroke when needed. ESD valves must be taken off-line to full stroke test which prevents them from performing ESD functions during the test. Human intervention is required to perform mechanical stroke tests putting key personnel at risk should an emergency arise. Mechanical partial stroke tests are time consuming and costly while preventing resources from being used elsewhere.For this project, the Valve Automation team provided a hydraulic partial stroke test and diagnostics system.
