A very clear tendency in this context is the use of

Moreover, the marine sector is very demanding, not only technically, but also in terms of project management. Professionals are required to have extensive experience in this highly specialized area.

Technically, this market is heavily regulated by

Another common characteristic is the use of integrated

TMC Transformers products are realized for distribution and special applications

: two very different souls combined together under a single roof, to offer to our customers the most suitable technology and service. The company is mainly working on 

dry type transformers and reactors for all the applications worldwide.

 We are talking about industry, simple distribution for building and infrastructures, traction substations, marine and offshore, oil and gas, renewable energy, battery storage, mining, data center, power plants, e-mobility.

The most innovative development concerns outdoor transformers where we introduced new ways to protect the transformers and innovative solution to cool it down. We can now deliver a proper solution for any specific ambient challenging the most polluted, humid or aggressive environment. 

As an example of this new innovation, we have recently done, on one side, an installation in a mine in the middle of the desert ,and on the other side, one in very snowy and cold area, close to the Arctic Circle.

The future of transformers' world

as the world's primary fuel sources. The processes and systems involved in producing and distributing oil and gas are highly complex, capital-intensive and require cutting edge technology.

The industry is often divided into three segments:

, the business of oil and gas exploration and production.

The upstream segment of the oil and gas industry contains 

, which include creating geological surveys, obtaining land rights and production activities, consisting of onshore and offshore drilling.

Oil and gas exploration encompasses the processes and methods involved in locating potential sites for oil and gas drilling and extraction. 

 are conducted using various means from testing subsoil for onshore exploration to using seismic imaging for offshore exploration. Energy companies compete for access to mineral rights granted by governments, by either entering a 

, meaning any discovered oil and gas are exclusive property of the producers, or a 

, where the government retains ownership and participation rights. Exploration is highly risky and expensive, involving primarily corporate funds. However, when an exploration site is successful and oil and gas extraction is productive, exploration costs are recovered and are significantly less impactful with respect to other production costs.

Oil and gas production is one of the most capital-intensive industries and it requires expensive equipment and highly skilled labour. Once a company identifies where oil or gas is located, plants begin by drilling. Many oil and gas companies contract with specialized drilling firms, paying for the labor crew and rig day rates. While every drilling rig has the same essential components, the drilling methods vary depending on the type of oil or gas and the geology of the location.

 facilities, the wells are grouped together in a field. The group of wells are connected by 

 that send the oil and gas to a production and processing facility, where the raw materials are treated through a chemical and heating process. Onshore production companies can turn on and off rigs more easily than offshore rigs to respond to market conditions.

that is either fixed (bottom supported) or mobile (floating secured with anchors). Offshore drilling is more expensive than onshore drilling, as are fixed rigs with respect to mobile ones. Most production facilities are located on coastal shores near offshore rigs.

 of crude oil, natural gas and refined products. In its unrefined state, crude oil is transported by two primary modes: 

, travelling interregional water routes, and 

, where most of the oil moves through for at least part of the route. Once the oil has been extracted and separated from natural gas, pipelines transport the products to another carrier or directly to a refinery. Petroleum products then travel from the refinery to market by tanker, truck, railroad car, or more pipelines.

Crude oil moves from wellhead to refinery using tankers, pipelines, trucks, and railroads. Natural gas is transported by pipelines and liquefied natural gas (LNG) tankers.

 (designed to carry oil or solid cargoes in bulk). Tank vessels are classified according to the different types and the three most common categories are crude oil carriers, product carriers (which can carry clean e.g., gasoline and dirty e.g. black oils) and parcel carriers (chemicals). Crude carriers are classed as either 

 (Ultra Large Crude Carriers) and are designed to transport vast quantities of crude oil over many, long and heavily traveled sea routes. In addition, "lightering," offloading or transferring oil from large tankers to smaller ones is used, so that the vessels can enter smaller ports.

: pipelines can refer to gathering systems (wellhead to processing facilities), transmission lines (supply areas to markets) or distribution pipelines (most commonly to transport natural gas to medium or small consumer units). 

Pipelines play a very critical role in the transportation process

 because most of the oil moves through them for at least part of the route. After the crude oil is separated from natural gas, pipelines transport it to another carrier or directly to a refinery. Petroleum products then travel from the refinery to market by tanker, truck, railroad tank car, or pipeline. 

involves determining the shortest and most economical routes where pipelines are built, the number of pumping stations and natural gas compression stations along the line, and terminal storage facilities so that oil from almost any field can be shipped to any refinery on demand. Offshore pipelines carry more risk for leaks and environmental impact than onshore pipelines, but technological advancements in pipeline material and monitoring systems have improved their safety and efficiency.

: high pressures and explosions make it difficult to transport compressed natural gas on tankers. Due to scientific advancements, natural gas can be turned to liquid at extremely low temperatures and transported as liquefied natural gas (

). LNG tankers are specially designed with double hulls, to allow extra ballast water because LNG is lighter than gasoline and has additional safety benefits.

were the primary means of petroleum transportation. Today, railroads compete with pipelines: despite being usually a more expensive solution, the already existing railroad infrastructure creates an alternative, more flexible route when pipelines are at capacity. Many petroleum products travel from refineries to markets by tank truck or railroad tank car. Tank trucks deliver gasoline to service stations and heating oil to houses.

of oil and natural gas helps smooth out supply and demand discrepancies. Companies store more when the prices are lower than they would like and withdraw when prices are high. The cheapest storage method is 

, such as depleted reservoirs. This method is primarily used for natural gas; finished oil products cannot be stored in underground natural spaces as per regulations. Above ground tanks are used for crude and refined oil, finished oil products, and natural gas. At retail locations, like gas stations, tanks are stored underground for safety reasons. Tanker ships are used for temporary storage when land storage is at capacity, making it the most expensive option.

. While refining is a complex process, the goal is straightforward: 

 which is virtually unusable in its natural state, and t

 products used for a variety of purposes such as heating homes, fueling vehicles and making petrochemical plastics. Refineries are usually located near population centers to facilitate marketing and distribution of final products. Marketing is the wholesale and retail 

 products to business, industry, government, and public consumers.

Generally, crude oil and petroleum products flow to the markets that provide the 

 to the supplier, which usually means the nearest market first because of lower transportation cost and higher net revenue for the supplier. In practice, however, the trade flow may not follow this pattern due to other factors, such as refining configurations, product demand mix, and product quality specifications.
