On December 10, 2005, Tank 912 at the Buncefield Oil Storage Depot in Hertfordshire, England, was filling with gasoline. According to a report by the European Process Safety Centre, the tank had two forms of level control: a gauge enabling personnel to monitor the filling operation; and an independent high-level switch (IHLS) which was meant to shut down operations automatically if the tank was overfilled.
The first gauge stuck and the IHLS was inoperable, so there was no means to alert the control room staff that the tank was filling to dangerous levels. Eventually, large quantities of gasoline overflowed from the top of the tank. A bund retaining wall around the tank and a system of drains and catchment areas that were supposed to ensure that liquids could not be released to the environment failed. More than 66,000 gallons (250,000 liters) of gasoline escaped from the tank before the explosion occurred.

Parker Hannifin - TwinZapp: Treating oil in water (OIW) emulsions for
discharge to sea.
The increasing water cut in mature fields and tightening regulations are the main drivers for the growing challenge of treating oil in water emulsions. In addition, the industry is creating more emulsions in novel applications such as Fraccing (Fracking), Well Deliquification, and Alkali Surfactant Polymer water as used in Enhanced Oil Recovery.
Installed treatment equipment often relies on time and gravity as the main forces for separation of water and hydrocarbons (Stokes’ law). For chemically stable emulsions these forces are not sufficient.
Parker Twin Filter has developed a technology based on its already extensive product line and experience in treating oilfield waste water. It uses the proven technology of electrical oxidation but uses this in a novel way to clean up water in a three step process.
The process is fitted on two mobile skids as an end-of–pipe solution. The input is water from the near atmospheric skimmer tank, the output is water which can be discharged to sea without further processing. The skids are self-sufficient, ATEX zone 2 certified, and only require electrical power and work air. It does not need regular attention from operators or specialists
because the output of NTU is monitored by sensor technology.
The process is now available as a commercial product or service offering after thorough field trials in 2012 and 2013. This white paper details a case study with GDF Suez E&P in which this operator increased gas production significantly through the use of TwinZapp. TwinZapp skid

Sil assessment Risk Graph and LOPA Training iFluidsJohn Kingsley
LOPA is the newest methodology for hazard evaluation and risk assessment. On a sliding scale of sophistication and rigor, LOPA lies between the qualitative end of the scale (characterized by methods such as hazard and operability, or HAZOP, analysis and what-if analysis) and the quantitative end (characterized by methods using fault trees and event trees). LOPA helps the analyst make consistent decisions on the adequacy of existing or proposed layers of protection against an accident scenario. The technique is ideally suited for companies striving to meet specific risk targets or to lower risk as low as reasonably practicable (ALARP).

Behaviour-Based Safety: The blame game
An entire department is given bingo cards. The game continues until someone in that department reports a work related injury or illness. At that time, everyone has to turn in his or her markers and the game starts over. Imagine the pressure on the poor worker who slices his or her finger or suffers some type of sprain, not to report an injury, because a co-worker is about to reach BINGO and win the VCR or microwave oven.
Sound familiar? Scenarios such as this are growing in frightening proportions as more and more workplaces are adopting behaviour-based safety programs as part of their health and safety arsenal. UFCW Canada opposes this type of so called Health and Safety program as this type of program also encourages workers to spy on their co-workers for working in an unsafe manner

A visual signal is a luminous source within a coloured transparent enclosure and is used in many applications not least as reinforcement to an audible signal in the event of danger, warning or machine status / system process.
Effectiveness of visual signals
With the possible exception of status indicators, the purpose of the E2S visual signals range is to attract attention as compared with a luminaire or general purpose light which is intended to illuminate a given area and not necessarily attract attention. Therefore the effectiveness or the light intensity of a device as opposed to merely its capacity to illuminate is probably the important consideration. Different light sources may offer significantly different effective light intensity and ability to attract attention, particularly when flashing; however in contrast their ability to illuminate a given area may be fairly poor.
E2S provides information relating to the effectiveness of a visual signal based on actual measurements for each model within the E2S range. The information provided IS NOT based on rule of thumb assumptions and / or calculations alone. We therefore have confidence our measured light output values are meaningful and will better aid product selection.
Introduction to bowtie : A barrier-based approach to riskJohn Kingsley
Bowtie is one of many barrier risk models available to assist the identification and management of risk and it is this particular model we have found (and are still finding) useful.
These pages explain:
what a bowtie can be used for,
how it can help you,
how to go about the methodology and
what to look for within a model.
The bowtie model consists of different elements that build up the risk picture. The risk picture revolves around the hazard (something in, around or part of an organisation or activity which has the potential to cause damage or harm) and the top event (the release or loss of control over a hazard known as the undesired system state).
Consideration is then turned to the threats (a possible direct cause for the top event), consequences (results of the top event directly ending in loss or damage) and the controls (any measure taken which acts against some undesirable force or intention

Memorandum Of Association Constitution of Company.pptseri bangash
www.seribangash.com
A Memorandum of Association (MOA) is a legal document that outlines the fundamental principles and objectives upon which a company operates. It serves as the company's charter or constitution and defines the scope of its activities. Here's a detailed note on the MOA:
Contents of Memorandum of Association:
Name Clause: This clause states the name of the company, which should end with words like "Limited" or "Ltd." for a public limited company and "Private Limited" or "Pvt. Ltd." for a private limited company.
https://seribangash.com/article-of-association-is-legal-doc-of-company/
Registered Office Clause: It specifies the location where the company's registered office is situated. This office is where all official communications and notices are sent.
Objective Clause: This clause delineates the main objectives for which the company is formed. It's important to define these objectives clearly, as the company cannot undertake activities beyond those mentioned in this clause.
www.seribangash.com
Liability Clause: It outlines the extent of liability of the company's members. In the case of companies limited by shares, the liability of members is limited to the amount unpaid on their shares. For companies limited by guarantee, members' liability is limited to the amount they undertake to contribute if the company is wound up.
https://seribangash.com/promotors-is-person-conceived-formation-company/
Capital Clause: This clause specifies the authorized capital of the company, i.e., the maximum amount of share capital the company is authorized to issue. It also mentions the division of this capital into shares and their respective nominal value.
Association Clause: It simply states that the subscribers wish to form a company and agree to become members of it, in accordance with the terms of the MOA.
Importance of Memorandum of Association:
Legal Requirement: The MOA is a legal requirement for the formation of a company. It must be filed with the Registrar of Companies during the incorporation process.
Constitutional Document: It serves as the company's constitutional document, defining its scope, powers, and limitations.
Protection of Members: It protects the interests of the company's members by clearly defining the objectives and limiting their liability.
External Communication: It provides clarity to external parties, such as investors, creditors, and regulatory authorities, regarding the company's objectives and powers.
https://seribangash.com/difference-public-and-private-company-law/
Binding Authority: The company and its members are bound by the provisions of the MOA. Any action taken beyond its scope may be considered ultra vires (beyond the powers) of the company and therefore void.
Amendment of MOA:
While the MOA lays down the company's fundamental principles, it is not entirely immutable. It can be amended, but only under specific circumstances and in compliance with legal procedures. Amendments typically require shareholder

At its core, generative artificial intelligence relies on the concept of generative models, which serve as engines that churn out entirely new data resembling their training data. It is like a sculptor who has studied so many forms found in nature and then uses this knowledge to create sculptures from his imagination that have never been seen before anywhere else. If taken to cyberspace, gans work almost the same way.
Enterprise Excellence is Inclusive Excellence.pdfKaiNexus
Enterprise excellence and inclusive excellence are closely linked, and real-world challenges have shown that both are essential to the success of any organization. To achieve enterprise excellence, organizations must focus on improving their operations and processes while creating an inclusive environment that engages everyone. In this interactive session, the facilitator will highlight commonly established business practices and how they limit our ability to engage everyone every day. More importantly, though, participants will likely gain increased awareness of what we can do differently to maximize enterprise excellence through deliberate inclusion.
What is Enterprise Excellence?
Enterprise Excellence is a holistic approach that's aimed at achieving world-class performance across all aspects of the organization.
What might I learn?
A way to engage all in creating Inclusive Excellence. Lessons from the US military and their parallels to the story of Harry Potter. How belt systems and CI teams can destroy inclusive practices. How leadership language invites people to the party. There are three things leaders can do to engage everyone every day: maximizing psychological safety to create environments where folks learn, contribute, and challenge the status quo.
Who might benefit? Anyone and everyone leading folks from the shop floor to top floor.

Hydrocarbon leak detection in tank farms
On December 10, 2005, Tank 912 at the Buncefield Oil Storage Depot in Hertfordshire,
England, was filling with gasoline. According to a report by the European Process Safety
Centre, the tank had two forms of level control: a gauge enabling personnel to monitor the
filling operation; and an independent high-level switch (IHLS) which was meant to shut down
operations automatically if the tank was overfilled.
The first gauge stuck and the IHLS was inoperable, so there was no means to alert the control
room staff that the tank was filling to dangerous levels. Eventually, large quantities of gasoline
overflowed from the top of the tank. A bund retaining wall around the tank and a system of
drains and catchment areas that were supposed to ensure that liquids could not be released to
the environment failed. More than 66,000 gallons (250,000 liters) of gasoline escaped from the
tank before the explosion occurred.

Figure 1 The Buncefield Oil Storage Depot explosion and fire could have prevented with a leak
detection system.
A vapor cloud formed, ignited, and caused a massive explosion and fire (Figure 1). The fire,
the largest seen in peacetime UK, engulfed more than 20 fuel tanks and burned for five days.
The explosion itself registered 2.4 on the Richter scale.Five companies were charged with
offenses arising out of the investigation of the Buncefield incident. Proceedings were
completed at St Albans Crown Court on 16 July 2010, and fines amounting to $5 million
(£4,081,000) were assessed.
Detecting Leaks
As a result of the Buncefield and other incidents, refining and petrochemical storage areas are
under increased pressure to monitor for tank leaks. Even when there are no explosions or fires,
leaks result in lost product and harm to the environment if retention areas are breached. Leaks
contained in retention areas also pose a problem as the affected area must be decontaminated.
Fuel leakages emit oil vapor, generating a hazardous area where a spark can cause an explosion.
Fuel has a high ignition temperature, but if the leakage goes near a heated point such as a

mechanical pump, it’s very difficult to fight the fire. Tank farms often have several pump
stations near retention bunds.
Hi-Hi level switches are increasingly being deployed, even in tanks that have an IHLS. The
Hi-Hi switch mounts above the high-level switch and acts as a second alarm switch. The
problem with a Hi-Hi switch is that it won’t be activated unless the first level switch fails, so
it may never be tested except during maintenance activities. Some switches have built-in
diagnostics that verify proper operation, but this is not a foolproof solution. Dual radar or
ultrasonic level instruments are also being used, with each acting as a backup to the other.
While level switches and redundant level instruments can guard against tank overflows, a
storage tank can leak from several sources such as inlet and outlet piping and valves, chopper
mixers, pumps and cracks in the tank. Because the storage tank is an “island” in the center of
a retention pond, fuel leaks drain directly into the pond, requiring the use of a hydrocarbon leak
detection system.
Unfortunately, the costs of installing wired hydrocarbon leak detectors can be very high. A
single storage tank may require six or more leak detectors, all of which must be wired back to
the automation system. Additional inputs may have to be installed at the automation system to
accommodate the new leak detectors, and application software for tank monitoring must be
configured to diagnose the inputs and signal an alarm.
Because of the high cost of leak detection, in an average refinery with 100 storage tanks, only
5% have leak detection. Considering that the U.S. currently has 122 refineries, that means more
than 10,000 storage tanks are operating without leak detection in U.S. refineries alone, with
tens of thousands more unmonitored tanks worldwide in refineries, tank farms and chemical
plants. One way to reduce the high cost of hydrocarbon leak detection is with WirelessHART
leak detectors, which not only cut or eliminate the cost of wiring, but also allow alarm
processing to be performed by a PC.
Detecting Hydrocarbons
Figure 2 The TraceTek TT5000 fuel sensing cable detects liquid hydrocarbons.
One type of WirelessHART hydrocarbon detection device is a TraceTek TT5000 fuel sensing
cable (Figure 2). The entire length of the cable is sensitive to the presence of liquid
hydrocarbons. The core of the cable is composed of a bundle of wires formed into a spiral
construction. Two of the wires are electrodes. The two electrodes have a metal conductor core
and a jacket of conductive polymer. The electrode wires are on opposite sides of the spiral

bundle of wires and do not touch each other. They are somewhat smaller than the other wires
in the core bundle. A tubular jacket of conductive, rubbery polymer is extruded over the top of
the wire bundle.
Monitoring circuitry constantly checks for any conductivity between the two electrodes. An
open circuit between the two electrodes is an indication that the cable has not been exposed to
hydrocarbons.When a liquid hydrocarbon comes into contact with the cable, a very small
amount of the spilled liquid will be absorbed into the rubbery tube, causing it to swell. After
sufficient fuel has been absorbed into the rubbery tube, it will thicken enough to come into
contact with the two electrode wires in the core of the cable.
When contact between the jacket with the two electrodes occurs, an electrical pathway exists
from one electrode wire to the other through the conductive material in the rubbery tube. The
monitoring circuit detects the sudden drop in resistance between the two electrodes and reports
via WirelessHART that a leak has been detected via a wireless mesh network.
Figure 3 Fuel sensing cables can be installed on a pipeline to detect leaks.
Sensing cables can be configured in various ways for mounting on pumps, valves and pipelines
(Figure 3) to provide local detection of hydrocarbon leaks.For leak detection in or near
retention ponds, the fuel sensing cable is installed in a TraceTek Fast Fuel Sensor probe. The
probe is immersed in the retention pond, where it is exposed to water. Should a liquid
hydrocarbon come into contact with the probe, a very small amount of the spilled liquid will
be absorbed into the polymer, causing it to swell.
The probe detects the sudden increase in conductivity and reports via WirelessHART that a
leak has been detected (Figure 4). Reaction time is typically less than a few seconds for light
or middle weight fuels such as gasoline, jet fuel or diesel. It is also responsive to crude oil and
some heavier weight fuels and heating oil, but response becomes progressively slower as fuel
viscosity increases and volatility decreases. In most cases, the sensor will reset when removed
from contact of the spill after the fuel evaporates.

Figure 4 The fuel sensor probe is immersed in the water-filled retention pond to detect fuel on
the surface (right). It can also be mounted on dry land to detect fuel (left).
Monitoring Retention Ponds
To monitor a retention pond, the probe is installed on a floating pad (Figure 5). This allows the
sensor to function in periods of drought, when the water level might drop or completely dry
up, or during rainstorms when the water can rise.Depending on the diameter of the tank, a
retention pond may require from one to six detectors. Typically, a field assessment is done for
each tank to determine the fuel flow, identify the hydrocarbon fuel being stored, calculate the
number of detectors needed, and determine where to place them. On large tanks—30 feet
diameter or larger—it may be advisable to also install leak detectors on the drain, valves and
chopper mixer. This is because a large tank has a large retention pond, and small leaks can be
dispersed in the water.
The WirelessHART transmitter sends data to a wireless gateway, which is hardwired to a PC,
usually via Ethernet. Depending on the distances between the leak detectors, the transmitters
and the gateway, a single Wireless Gateway may serve the entire tank farm.
At the PC, software analyzes the data from the detectors and proves and sounds an alarm if a
leak has occurred, and provides leak location information.

Figure 5 The fuel sensing probe is mounted on a Vegase floating pad (blue, center) so it can
operate with or without the presence of water, or rise with the water level. The probe has a
WirelessHART transmitter installed at the top.
Monitoring Tanks and Ponds
At a tank farm in southeastern France, Vegase installed hydrocarbon leak detectors on 46
storage tanks (Figure 6). As the map shows, some tanks required only one detector, while others
required 2, 3 or 4 detectors.
The entire tank farm required 141 detectors. The project was accomplished in three phases,
following a single-tank test case in 2012. Phase 1 in 2013 added 18 tanks with 52 detectors,
Phase 2 in 2014 added 12 tanks with 28 detectors, and Phase 3 in 2015 added the final 15 tanks
with 58 detectors.
In this refinery, the tank farm is on a mountain with a big retention bund. Floating detectors
are placed in the retention ponds surrounding tanks, taking into account the normal flow of rain

water, while fixed point detectors (without floating devices) are put on the opposite flow line.
This ensures detection no matter where a leak or spill progresses.
Figure 6 Installation at a tank farm in France, showing about one-third of the farm. Blue and
green dots show the placement of leak detectors, yellow dots show wireless repeaters, and the
red box shows the location of the Emerson 1420 wireless gateway in the control room.
The gateways and repeaters gather data from the detectors, provide redundancy, and ensure the
data arrives at the main gateway in the control room. The main gateway is hardwired to a PC
via Ethernet, and the PC is connected to the automation system via a hardwired Ethernet link.
At the PC, software analyzes the data from the detectors, and proves and sends an alarm to the
automaton system if a leak has occurred. Facility personnel can then go to the PC and view
leak location and other detailed information.
Today, the entire tank farm is covered with leak detectors for 100% coverage. The cost for the
entire turnkey system was about $1 million, one-third the cost for a wired system, and the
system has been operating to the satisfaction of the facility since its installation.
