Products are designed for clamping and holding parts while a secondary operation is performed through the open center. A typical application is where a flexible diaphragm is clamped between two metal retainers while a rivet or other form of fastener is added to the assembly thru the open center. The product line includes seven sizes from three inch O. Control is with plant air using a typical four way pneumatic valve circuit either manually operated for work close at hand or solenoid operated for remote locations as part of an automated process. The MSD induces faster solenoid pull-in with a high input voltage then automatically reduces voltage during hold-in. This not only increases efficiency but extends solenoid life and saves energy.

The Chevron-led project west of Onslow, Australia completed offshore platform hook-up and commissioning required for LNG Train 1 start-up. Woodside informed in its quarterly report that the trunkline is pressurized and ready to supply gas onshore where LNG Train 1 final commissioning is well advanced and nearing completion. The start-up of the second liquefaction train is expected six to eight months after the Train 1 start-up. LNG cargo deliveries and Pluto expansion plans Woodside, that reported a With the outages, the North West Shelf project delivered 60 cargoes, while the Pluto LNG plant exported 16 cargoes, achieving daily and weekly production records along the way.
Woodside noted that studies on the expansion of the Pluto LNG plant have progressed with concept options nearing completions. Expressions of interest have been sought for FEED and the development of binding EPC bids to support planned final investment decision in the second half of
Construction, Installation and Commissioning
Origins[ edit ] In , Henry Sutton developed a Telephane for closed circuit transmission of pictures via telegraph wires, based on the Nipkow spinning disk system, so that the Melbourne Cup could be seen in Ballarat. Reports differ on whether the Telephane was successfully implemented. The test transmissions, which were of 1 hour duration each day, were made by Thomas M.
Hook-up and completion covers all necessary activities preparing for the start-up of oil and gas production. It is the final phase in preparing new developments or modifications at .
Data on the highest daily production that is achieved with the present hardware should also be captured. In addition to the past production performance of the units, a breakdown of individual equipment must be assessed to identify the weak areas and arrive at the predicted performance in the post-revamp implementation scenario. The best yearly, monthly and daily performance must be considered in order to find the target capacity of the plant and identify the number of stream days that this target capacity is likely to achieve.
Analysis of historic downtime factors can also provide insight. To assess the feasibility of the plant operating at higher capacity, the best-achieved PLF on a monthly basis , and the highest load achieved, should be considered. In any process plant, onstream days are lost due to various factors — including process problems, mechanical breakdown of equipment, raw material shortages, planned shutdowns, finished product sales, effluent treatment and byproduct sales if any.
Such lost days — which contribute to a loss of overall capacity utilization — should be tabulated, and the associated causative factors noted and tabulated. From the weak-area analysis, one can estimate the inherent capacity potential of the plant and identify individual equipment components or sections that are becoming a bottleneck to maximum capacity utilization.

The single integrated topsides structure shall be installed by another contractor utilising the floatover method, allowing for maximised onshore fabrication yard commissioning activities. Offshore North West Shelf – After the platform floatover is performed by the EPCI contractor, the Topsides to SGS hook up will commence, which shall include, but not be limited to; process risers, caissons, umbilical J tubes, structural legs and caisson pump installations.
Upon construction completion of these activities, pre-commissioning and commissioning of the Hook Up systems will commence using the CMS leading to handover of the Topsides and SGS completed systems to Company.
Ranger Offshore has extensive experience in providing platform hook-up and commissioning services on both new and existing platforms through its in-house personnel and strategic partners.
New York South East Post] T-Mobile hailed the results as evidence that its network was on par with market leader Verizon and said any differences in rural coverage would be addressed as it begins to roll out spectrum in the MHz band. Business Services has been witnessing strong momentum and continues to represent an attractive growth opportunity for the company.

OFFSHORE DESULFURIZATION UNIT PERMITS GAS LIFT OPERATIONS
The FISCO concept was optimized in order to permit a greater number of field equipment, according to the bus length and considering the variation of the cable characteristics R’, L’,C’ and terminators to satisfy categories and groups of gases with a simple evaluation of the installation involving intrinsic safety. With this, the capacity of current per segment was increased and the evaluation was facilitated for the user.
Furthermore, when acquiring certified products, the user no longer needs to worry about calculations, even for replacement during operation. Figure 3 — Example of Manchester codification An equipment transmission typically supplies 10 mA to Figure 4 – The total cable length is the totality of the trunk size main bus and all spurs derivations bigger then 1m , bearing in mind that with the A type cable, the length is a maximum of m in unsafe areas.
Hook-Up & Commissioning. Sembmarine SLP’s first objective with regards to offshore hook-up and commissioning is to maximise onshore pre-commissioning, which in turn allows minimal offshore hook up and commissioning hours.
In that deregulated market, responsibility for reliability has been largely transferred to the Electric Reliability Council of Texas ERCOT , an independent system operator regulated by the state Public Utility Commission. Gencos are, however, given financial incentives to provide services and products to the market, and they respond to these incentives in the same way that they respond to a need to maintain a reserve margin or another reliability-related parameter.
The amount and type of power supply capacity in ERCOT has changed dramatically over the past eight years for two main reasons: Power producers responded to these two events by mothballing or decommissioning around 10, MW of older gas-fired steam plants whose marginal operating costs could not compete with those of the combined-cycle plants.
Every owner of an older gas-fired steam plant had to decide whether to throw in the towel or find something other than capacity that the plant could sell profitably. Another MW unit was commissioned in , and a third, rated at MW, went commercial in The old plant shares its site with the Lost Pines 1 Power Project, a gas-fired combined-cycle plant that came on-line in May Figure 1.

For starting up a process control system I am used to this routine: Install the various subsystems. Perform hook-up of the subsystems. Post-installation testing of the subsystems: What should be in pre-commissioning and what should be in commissioning? Is pre-commissioning at the subsystem level and commissioning at the system level? Our commissioning would normally also include displacing storage or transportation fluids from process and utility lines, replacing them with the working fluids, but most of this would be outside control system scope.
Startup of the process: This routine is used for bringing on the control system for a reasonably complex process on a fairly large scale. The general definition seems to be that commissioning is the work required to bring a system to the point where it can be used. This may include leak tests, continuity tests and functional tests.
