Pipeline Construction

Coal seam gas also known as coal seam methane is composed from the coal and has been  controlled with and under pressure. Coal seam gas is essentially composed of methane gas, which is also an essential and integral part of natural gas. Coal seam gas normally has minor levels of carbon dioxide and when compared to other natural gas deposits sometimes this can alter. Coal seam gas refers to the methane that is engrossed into the solid matter or matrix of coal. Furthermore, coal seam gas is known as sweet gas because it lacks hydrogen sulphide. The existence of this gas is well known; it is pre dominant in underground mining where it is deemed a peril if proper precautions are not taken.

The Pipeline construction comprises three stages:
·        Pre-construction planning
·        Implementing construction work
·        Post-construction

Each stage needs a committed cluster of general contractors, engineers, construction labourers and project managers. The planning phase of pipeline construction has engineers that perform design layouts and ensure the project is scrutinised. Many components are considered during this stage including size, kind, and structure of pipeline, and processes that will be employed to lessen circumstantial impact. The construction stage of a pipeline construction is categorised into three phases. The first comprises clearing and sorting the land and quarrying furrows. The second entails adhering and welding pipes, then establishing the joined pipes into gorges. The last entails testing the pipeline; backfilling trenches; and fixing the land.

A vital part of pipeline construction is being able to acquire adequate pipes to complete the project. The tsunami calamity that hit Japan has generated a deficit of products used to form pipes. The ascending cost of crude oil, fuel, and the constituents needed for constructing resin has resulted in an accession in pipeline pricing. Pipeline construction contractors are accountable for all aspects of the installation method. Any kind of pipeline construction project initiates only with years of preparation. It is essential to plan for the time to ensure nothing goes wrong. Steps are involved also in planning for the pipeline construction and entails identification of market needs, designing the pipeline, specification of elements and choice of route, environmental assessments, public deliberation, consents and land procurement. The extraction process of coal seam gas is fairly challenging. It requires an ample amount of drilling, tubing, and water pumping. Although there is a range of distinct procedures, pipeline construction, which is at the initial stage, is possibly one of the most significant. The infrastructure of the course of action can mean a distinction between the breakdown and success of the endeavour.

Coal seam gas is being used worldwide today for numerous reasons and is becoming a chief part of natural gas.

Lean and Pipeline Construction Australia

Lean Construction Australia is a production management-based approach to project delivery -- a new way to design and build capital facilities. Lean production management has caused a revolution in manufacturing design, supply and assembly. Applied to construction, Lean changes the way work is done throughout the delivery process. Lean Construction Australia extends from the objectives of a lean production system - maximize value and minimize waste - to specific techniques and applies them in a new project delivery process. As a result:

•    The facility and its delivery process are designed together to better reveal and support customer purposes. Positive iteration within the process is supported and negative iteration reduced.
•    Work is structured throughout the process to maximize value and to reduce waste at the project delivery level.
•    Efforts to manage and improve performance are aimed at improving total project performance because it is more important than reducing the cost or increasing the speed of any activity.
•    "Control" is redefined from "monitoring results" to "making things happen." The performance of the planning and control systems are measured and improved.

The reliable release of work between specialists in design, supply and assembly assures value is delivered to the customer and waste is reduced. Lean Construction Australia is particularly useful on complex, uncertain and quick projects. It challenges the belief that there must always be a trade between time, cost, and quality.
Building on teamwork, lean project delivery takes cooperation in construction to the next level. The owner, designer, builder and all other critical players in the project are treated as equals on a single team. These various players focus on reliability in meeting the commitments they make on a project. When more companies reliably meet their commitments, the overall project proceeds more smoothly. This avoids the inefficiencies that result when team members look only to their individual productivity and profit at the expense of the group. Team members share financially in the risk of loss on the project and are rewarded by incentives if project goals of cost and schedule are attained.
There are other inherent benefits besides financial incentives that build a compelling case for lean construction Australia. Lean construction Australia focuses on the elimination of waste. In particular, the following are reduced, if not eliminated, resulting in potential cost savings of 20% or more: over-production, waiting, unnecessary transport, over-processing, excess inventory, unnecessary movement, defects and wasted talent.
By rewarding collaboration so that individual players focus on optimizing the whole and not the pieces, the work flows smoothly and reliably and quality improves significantly. The goal is to preserve a combined design and construction contingency through the elimination of inefficiencies.
Planning for any type of pipeline project often begins years in advance of actual construction. Initial steps in the planning process include determining the market need, pipeline design, specification of pipe and components, route selection, environmental assessments, public consultation, land acquisition and permitting. A Pipeline Construction project looks much like a moving assembly line.  A large pipeline construction project typically is broken into manageable lengths called “spreads,” and utilizes highly specialized and qualified workgroups.  Each spread is composed of various crews, each with its own responsibilities.
Steps in the pipeline construction process:

•    Clearing, grading and trenching
•    Stringing and welding pipe segments together
•    Depositing the pipeline, backfilling and testing
•    Restoration

As one crew completes its work, the next crew moves into position to complete its piece of the pipeline construction process.  Each spread may be 30 to 100 miles in length, with the front of the spread clearing the right-of-way and the back of the spread restoring the right-of-way.

Coal Seam Gas Australia

Coal Seam Gas (CSG) is natural gas found in coal deposits in Australia. The coal and gas are formed from plant matter under pressure over many millions of years. Coal seam gas in Australia is used in the same way as any other form of natural gas for cooking and heating as well as in industrial processes and electricity generation. Coal seam gas in Australia collects in underground coal seams by bonding to the surface of coal particles. The coal seams are generally filled with water and it is the pressure of the water that keeps the gas as a thin film on the surface of the coal (the technical term for this is 'adsorption').The coal seams generally contain more brackish (salty) groundwater than aquifers that are usually used for agriculture.
Underground, CSG is typically attached by adsorption to the coal matrix, and is held in the coal underground by the pressure of formation water in the coal cleats and fractures. The level of gas that can be produced from a coal bed depends on the thickness of the coal, gas content, permeability and the depth of the coal seam. In high quality CSG deposits the cleats or fractures in the coal bed are permeable enough to allow gas and water to flow freely through them. Coal seams that can produce CSG economically are usually 200 to 1,000 metres below the surface.
In Australia, CSG is plentiful. Coal Seam Gas (CSG) is methane gas found in coal seams. Often referred to as "unconventional Gas", CSG should not be confused with Liquid Natural Gas (LNG) which is also known as "conventional gas".   CSG is a newer resource extracted from coal deposits that are too deep to mine economically. The methane lies in pores and ‘cleats' in the coal seams and is trapped there by water. When burnt, methane produces about 40% less greenhouse gas than coal. Un-burnt it is at least 20 times more polluting than carbon dioxide (CO2). The process of removing methane from a coal seam sees a large amount leaking into the atmosphere, adding significantly to greenhouse pollution.
Coal seam gas (CSG) in Australia is an odorless, colorless natural gas created over millions of years as a by-product while organic matter is turned into coal. This gas, mainly comprising methane, is trapped on the surface of the coal. Australia has sizeable quantities of this resource, mainly in Queensland and NSW. Although it is not currently widely used throughout the country, there is a lot of research looking at this method's potential to contribute to Australia's energy supply. Queensland is the country's largest consumer of CSG, comprising more than 70% of the state's gas supplies.

As coal is formed, methane, carbon dioxide and water are generated. While most of these gases and water escape naturally, some of it is trapped in the coal seam. The gas is extracted through the removal of the water which is contained within the coal seams. When this water is released, the gas is also discharged. Just like with other gases, Coal seam gas in Australia can be used to drive turbines and create electricity. There are several advantages from using coal seam gas to generate electricity:
•    CSG is one of the cleanest of fossil fuels
•    It is relatively inexpensive
•    Its production creates water as a by-product
