Successful Flushing of 16" X 2pcs Floating Hoses SPM to 50km pipeline .

Disassembly of Bearings For extracting the bearings, their housings are first subjected to remove. Then, the upper bearing liners are removed. Upper labyrinths packing are keyed into the upper housing with lock key; whereas, lower ones are freely inserted into the lower housing, at GE MS5002D - The first bearing housing encloses the 1st journal bearing and active and inactive thrust bearings. - The housing is firstly unbolted and then upper half is uplifted with the eyebolts #Major_Inspection #Gas_Turbine #LNG #Rotating_equipments

#CARP_weekly_info - Part 64: MICP (16): Hg Capillary Entry Pressure for Pore Types. Capillary entry pressure is a measure of the OWC(s), GWC and GOC in a reservoir. The capillary entry pressure depends on porosity, pore type and hydrocarbon type, more specifically their contact angle and surface tension. Porosity and pore types vary throughout the reservoir, giving variable contacts within the reservoir, and in some cases multiple contacts within a well. As such the different contacts, especially the OWC, are dependent on reservoir quality and varies laterally within a field. This differs from the FWL, which is independent of reservoir quality and is usually constant within each reservoir compartment of a field. Several interactive prediction tools for capillary entry pressure are available in CARP. These tools predict the capillary entry pressure for mercury, oil and gas at different porosities, pore types and pore-type groups. This post will be on prediction of capillary entry pressures for pore types. Please note that the predicted capillary entry pressures may deviate slightly from that derived from the predicted MICP curves, as presented in post #45. The reason for this is that the latter is based on averaging the MICP curves (curve fitting) whereas the former is based on averaging the measured entry pressures. The capillary entry pressures presented in the current prediction tool is the most accurate.

The following short video is the introduction to smoke control in atrium. Some engineers ask me whether every smoke reservoir in a large space should be sized to the flow rate calculated or the total flow rate of all the reservoirs to be the calculated flow rate. Well, the answer would be every reservoir should have its dedicated fan sized to the calculated flow rate. This is because smoke engineering concept is the entrainment of air into smoke plume to rise up to the reservoir and to maintain the smoke layer. Thus a fan located in another reservoir would serve no purpose to entrain air into the plume located below the said reservoir. click to learn and register smoke control in atrium using BS, MS and BRE method. https://lnkd.in/gBMy2SUU

Horizontal Directional Drilling (HDD) is a remarkable trenchless technology that minimizes surface disruption while installing pipelines, conduits, or cables. I had the opportunity to use HDD on one of my projects to connect Jizan City-2 132/13.8 kV S/S with the network UGTL. The process of HDD involves three stages: 1️⃣ Pilot Hole Drilling: Creating a small-diameter pilot hole along the designed path. 2️⃣ Reaming: Enlarging the pilot hole to suit the pipeline's diameter. 3️⃣ Pullback Installation: Pulling the pipeline into the enlarged hole. Here’s a short video from a recent project where HDD was carried out on a busy road. You can see how the technique allows uninterrupted traffic flow while completing critical underground installations—a perfect example of balancing progress with convenience! #HDD #UGTL #JizanCity2 #Substation #TrenchlessTechnology

Influence of AC Stray Current on Cathodic Protection of Buried Pipe • Stray current interference from AC high voltage power lines and AC-powered electric railways can cause corrosion and damage to buried oil or gas pipelines. • The study constructed an indoor stray current interference experiment to investigate the interference principle of cathodic protection systems caused by stray current. • The results showed that different pipeline anti-corrosive coating damage areas have little impact on the cathodic protection potential of the pipeline, but the decrease trend of cathodic protection potential would be significant with the increase of the pipe length and damaged area. • When the damaged area reached 300 mm², the difference of the real value reached the maximum, indicating that the real protection voltage was minimal while the damaged area was 300 mm². • The parallel spacing between the pipeline and the interference source also affects the cathodic protection system. When the parallel spacing increased from 0.2 m to 1.0 m, the measured potential values decreased from 1.06 V to 0.98 V, while the real value increased from about −0.85 V to −0.75 V. • High alternating stray current intensity can cause serious negative offsets, leading to overprotection and cracking of the pipeline coating. • To assess stray current interference and the risk of stray current corrosion, a comprehensive analysis of cathodic protection energizing potential, switch-off potential, AC pipe-soil potential, IR drops, and other factors should be conducted. https://lnkd.in/ekUq3Pbs
