In a Farming Field area, there is a need of proper water supply to prevent it from drying and avoiding the over flow condition. If the water level in a Borewell connected near to the field drops below the threshold level for irrigation and Field starts drying and also its pump motor may get air-locked or even burn out due to dry running. It is inconvenient for farmers to walk all the way to their fields at night just to switch the pump motor ‘off.’ Besides, he may never get to know the problem. This problem can be solved by using this GSM-based system that will automatically give the user a call on his mobile phone when the water level in the Borewell drops below or rises to the threshold level for pumping. The user can also remotely ‘switch on’ or ‘switch off’ the pump motor by sending a sms from mobile phone.

China has a rapidly developing submarine cable system manufacturing industry which operates in a healthy competitive manner. Subsea cables can fall into several different system product streams including relatively standard products for long haul telecoms projects (the subject of this paper) and customised products for the Oil & Gas, Scientific Observation Systems, Defence applications and HV subsea cables. While much of the Telecoms product has been sold in the domestic market, Hengtong Marine has broken into the International Market by addressing client concerns over quality and now has a track record for deployed overseas systems. This has been achieved in part by completing an offshore cable system sea trial, which is a requirement of the cable system qualification to ITU-T G-976 & ITU-T G.972 standards. The requirement for a sea trial is a barrier which every cable system producer has to address to achieve international sales. Hengtong Marine is moving forward to promote and improve the image of “Global Quality from China”.

This requirement was for an international offshore drilling contractor that provides oilfield services for offshore oil & gas production, specialising in the ultra-deepwater sector. They needed ATEX Zone 2 rated load shackles with displays
and alarms for one of their deep water drillships that was being deployed off the Angola coast on the ultra-deepwater Kaombo project. Due to their clients stringent rules regarding hazardous areas, they needed certified products in order to comply. LCM Systems designed a system to meet their requirements that comprised of 3 x 12 tonne
environment, all cable supplied was RFOU (I) 250V armoured mud resistant power/instrumentation cable, specifically designed for safety critical systems in both EX and safe areas.
The load shackles were required to monitor the loads on umbilical roller sheaves as they payed out the hose to ensure that it did not become sagged and to check that the hydraulic hose reels were operating correctly. Each load shackle had its own display to show the individual loads, and all three were set to trigger an audio and visual alarm in the event of a pre-set limit being reached. A second display and alarm system was incorporated into the drilling cabin for remote system monitoring.
We subsequently received an identical order for the same system for another deep water drillship operator working on the same project.
load shackles and an ATEX junction box to be situated at the top of an A-Frame, which was wired to another ATEX junction box at its base and connected to 3 channel ATEX display and alarm system (see photo below). Also connected to this junction box was an additional display and alarm system located below deck in the driller cabin, which, because it was located in the Safe Area, was not required to be ATEX certified. Due to the harsh operating environment, all cable supplied was RFOU (I) 250V armoured mud resistant power/instrumentation cable, specifically designed for safety critical systems in both EX and safe areas.

LCM Systems are a designer and manufacturer of standard and custom design load cells, load pins and instrumentation systems. These are used in a variety of applications, including Marine, Offshore, Oil & Gas, Heavy Lift and crane safety. We also offer an extensive range of ATEX and IECx hazardous area certified products.
Larsen & Toubro, a leading Indian engineering and construction contractor, were commissioned to build a nuclear containment building at Kakrapar Atomic Power Plant. As part of the project they needed to lift and position a 47 metre
diameter and 8.25 metre high inner containment dome liner, which had been built as a single unit. Because of the unique geometry of the dome and its 365 tonne weight, a balanced lift with equally distributed loads was vital to ensure a safe and successful lift. Eighteen lifting lugs were integrated into the dome liner, which were each fitted with
loaded throughout the lift. With only 200mm clearance to work with, the Larsen & Toubro team lifted and placed the dome into position on top of the inner containment wall in just two hours, with alignment and anchoring taking a further three hours, after which the crane was released.
Larsen & Toubro commented “During test runs the turnbuckles where rotated according to the load displayed on all 18 load shackles to distribute the loads equally. This test was demonstrated to our client and the regulatory board, who were then happy to give their permission to lift the dome on the very next day.”
a 55te wireless load shackle. At the customers request, a Crosby G2130 was used, rather than the smaller standard TELSHACK-B 55te, as it afforded a better fit within the lifting lugs.
LCM Systems also supplied a telemetry base station that detected the telemetry signals from the load shackles and transmitted them to a laptop, where engineers were able to view the loads on each lifting lug to ensure they remained uniformly loaded throughout the lift. With only 200mm clearance to work with, the Larsen & Toubro team lifted and placed the dome into position on top of the inner containment wall in just two hours, with alignment and anchoring taking a further three hours, after which the crane was released.
Larsen & Toubro commented “During test runs the turnbuckles where rotated according to the load displayed on all 18 load shackles to distribute the loads equally. This test was demonstrated to our client and the regulatory board, who were then happy to give their permission to lift the dome on the very next day.”
We were contacted by a longstanding
customer about the feasibility of supplying them with a SOLAS compliant container weighing system. We had been supplying this specialist straddle carrier and forklift manufacturer with container weighing
systems for around five years, which they offered as an option on their straddle carrier range. With the introduction of updates to the SOLAS regulations, which stipulates that all containers must have a verified weight prior to shipping, they wanted a bespoke system to meet the standard that could be fitted to their equipment.
To meet the new legislative requirements, LCM Systems had to redesign the electronics of their existing system, and also introduce a new tablet display that showed the load on each individual pin and the total weight. Two existing load bearing pins were replaced with custom designed 25 tonne load measuring pins, which connect to an interface module where the mV/V output signal is converted to RS485 and the data then sent to the in-cab tablet display.
The new system was designed with pre-wired cable assemblies for connection to the interface module to allow installation to be carried out by untrained personnel, and also to facilitate fast and easy replacement of cables in the event of any becoming damaged. The tablet display, in addition to showing weight information, also has an in-built function that only allows the weight to be recorded once stable to ensure accuracy. It also includes a tare function and the facility to enter container numbers and generate reports.
For this project, we were contacted by a manufacturer of diving equipment, who were interested in having custom design load pins manufactured that were suitable for use in a marine/offshore environment. Because they would be used in a lifting
application that involved personnel, the traceability requirements were high, with 3.1 material certificates and charpy testing required. These load pins were required to measure the loads applied to the handling systems of the diving bells. The diving bells
are lifted ready for deployment through a dedicated opening in the centre of the vessel called a moon pool, and are also recovered using the same lifting system. Next to the moon pool there are a series of vertical sheaves, which connect to the diving bell. The plan was to have load pins installed in these sheaves to determine the weight of the diving bell. This would ensure that there were no overload situations, which could potentially endanger the personnel inside.
Four load pins are installed per moon pool lifting system, each rated to 1000kN. Manufactured from stainless steel and with
environmental sealing to IP67 for suitability in a marine environment, the load pins feature an internal amplifier to provide 4-20mA output. This allows the load measurement data to be exported direct to the vessels PLC system, where the results can be displayed and monitored for safety purposes.
The load pins were designed, manufactured and delivered within the required time frame, and the customer was very happy with their performance. They have since gone on to place orders for several more systems.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.
