Reducing the Impact of Decommissioning
Decommissioning can often be a lengthy, expensive process and it is important to draw on the expertise of experienced individuals that can serve to make the decommissioning of an abandoned offshore installation as simple as possible. There are numerous techniques and, as is typical of the industry, new services are always in development, created with the intention of making abandonment of a rig simpler and more cost effective.
Claxton Engineering are at the forefront of such technology, relied upon by numerous oil drilling operators around the world to ensure that any decommissioning of platforms is carried out quickly and safely, regardless of the reason for abandonment. One such innovation is the Claxton SABRE abrasive cutting system, which was designed to sever all casings within a well at the same time while taking into account the environmental impact. The SABRE system is without doubt one of the most environmentally friendly tools in the world for quick, safe abandonment.
While the system is only one of a number of specialist services offered in the world of decommissioning, it is vitally important to any drilling company to ensure that the abandonment process is carried out cheaply and safely. Any errors have an impact not only on the company’s own bottom line, but can also lead to conflicts with international regulations if the project is not thoroughly managed. Aside from the financial aspects, many companies will also hold their own environmental policies. The scrutiny under which such companies are held means that their responsibilities are magnified in the eyes of stakeholders and regulators.
On some occasions, it is simply not possible to remove a structure entirely. Larger structures, and particularly those that are buried deep into the sea bed, will offer fewer options for removal. There can be negative aspects to doing so, such as the impossibility of reusing parts of the structure in the future. However, these negatives are often outweighed by the costs involved. Again, it is preferable for such processes to be professionally managed, and while many companies have internal expertise in the area, they will often benefit from bringing in external knowledge to ensure costs are reduced to their lowest level and that the overall environmental impact is minimised.
Claxton Engineering offers such expertise, with the majority of their operational staff devoted to the mechanics of oil platforms, including not only development and maintenance, but also fully compliant abandonment. The three step process is often undertaken by a third party, who independently monitors the planning, permitting and implementation and are responsible not only for the removal of the rig, but also the associated clean-up caused by the day to day operations carried out thereon, such as removal of additional materials that collect at the base of the rig.
Protecting and Maintaining Pipelines with Subsea Services
Pipelines are valuable to industries around the world. They ensure that oil and gases are transported along the ocean bed and delivered to companies that will then distribute these resources around the world. Simply installing the pipelines is not always sufficient, however. Subsea services might be asked to install another set of pipelines and they need to ensure that the existent pipeline is not damaged in the process.
Preparing For a Crossing
When to pipelines are going to run across each other, measures need to be taken to ensure that the existing pipeline is not damaged. In order to protect the first pipeline, subsea services will usually use a specific measure to lay the second line across the first without putting the first line in jeopardy. These measures will differ according to the results of the surveys and preparations that are conducted by the engineering companies but it is usually the most plausible one that is chosen for the job.
Laying Mattresses across the Pipeline
When an engineering company intends to lay a pipeline across an existing one, they will need to make use of certain measures to ensure that the first line is safe from damage. One of the ways in which this can be done is by laying mattresses over the first line before installing the second one over it. These mattresses are actually concrete bricks that are then connected by cables. Once these have been placed down the second pipeline can be placed on top without damage to the first line.
Trenching is another way that pipelines can be protected while they are on the ocean bed. Certain dangers can render a pipeline useless and they will need to be protected from these. Trawlers can be especially harmful to these pipelines and trenching allows the pipelines a certain amount of protection. Trenching occurs when subsea services lay their lines in a trench on the ocean bed, making it difficult to be accessed and damaged by trawlers or other harmful devices. With the pipeline out of the way, companies do not have to worry about their precious pipelines being damaged and costing them revenue in the process.
Creative Thinking Is the Key
Although there are many ways in which a company can ensure the safety of their pipelines, it is usually creative thinking that allows engineers to solve problems such as these. Companies are always looking for individuals who show these skills because it allows them to come up with more efficient and cost-effect measures of solving problems in the field. These creative skills are used throughout the engineering field and it is this that has assisted many companies in broadening the technologies that are used in this industry.
HPHT operations and the need of advanced technology
High pressure and high temperature than the conventional one is a very harsh environment in reservoirs. The oil industry and the gas industry require new technology in drilling, evaluating and the completion of the task. They also need newly designed and produces equipments and tools to withstand the harsh conditions in HPHT reservoirs.
There are very efficient and high quality researches and development of HPHT technologies that are carried out by many service providers as well as engineering firms and construction researchers. Many technologies are invented and being invented to face the challenges and barriers faced in the HPHT reservoirs to be used now and in the future. Safety is a very important factor to be considered when it comes to HPHT condition. Many service providers are much keen on developing technologies related to the safety issue in HPHT environment where things can be very highly hazardous.
The reliability of the equipments and tools in the HPHT conditions is very important and a key factor to consider when working in a HPHT environment. Service providers are building up new strategies to withhold the harsh conditions in the HPHT environment. New equipments and tools are available today in the market to make the work easier as well as safer and time consuming in the HPHT reservoirs. The service providers are using well advanced and high technologies to design and manipulate new equipments and tools to be used in HPHT environments. These have turned to be very positive for companies to invest on HPHT reservoirs for development and explorations. And these companies have no more fear in investing for the high yielding HPHT reservoirs.
As time dodges off, technology and inventions develop day by day. Investments prosper in high number into the HPHT reservoirs. And probably there will be high prosperity in the HPHT reservoirs in the future.
Benefits of Hot Tapping
Hot tapping is also termed as pressure tapping. In this type of tapping you don’t have to empty the pipe during modifications made to the same pipe. This is a style to connect the existing pipe or vessels without shutting down the complete system. Hot tapping can be successfully used with the pipe containing water, petroleum gas, natural gas, steam, and chemicals. The tapping is suitable with all pipes made up of any material. The process is used at the locations where pressurized tabular water system exists like gas production plants, offshore platforms and refineries.
Hot tapping is the basic step in line stopping. The process has a number of advantages. You don’t have to stop the work during maintenance. Work is in progress without halting the other sections. The process is modular. Modular means it is able to handle different applications side by side. The process is also able to maintain the pressure. You can cut the hole of variable size in the pipe virtually. The process can only be controlled by the amount of pressure contained in the vessel or pipe. The complete process also has the flexibility feature. This feature makes the hot tapping more in demand.
This tapping can be done in two ways. The first way is automatic and other style is manually. This process is also successfully used on the subsea surfaces. You can also use different power options like hydraulic and pneumatic power system. Even drill length can also vary in size. You can make a small or big hole in existing pipeline. Hot Tapping is considered as safe and best style of repairing and modifications in existing pipelines. Not many people are aware about the concept of hot tapping. You can easily get the information over internet. This is a growing trend in the modern array.
You already know that hot tapping can be used with all materials. The most common materials are stainless steel, cemented pipe, plastic pipes, carbon steel pipes and fiberglass pipes. This is easy to make modifications in all materials. You can easily add new pipes to the existing pipes. This welding is also suitable with the pipe that can be easily welded. The most common type is cast iron. Cast iron is famous for its welding feature. The process is completed with power. Sometimes it is necessary to add custom made materials with the pipes.
When you don’t want to block the entire system not even a small part and you want to make modification in your pipe then this tapping is the best selection for everyone. Now you know why hot tapping is best option to operate. The process also has endless benefits. You can even use the process on any kind of material. You can even bore a small or big hole in the pipe.
