DID YOU KNOW? This is what an oil platform looks like before being submerged in the ocean.
The largest object in the world is made of concrete.
Wonders of engineering.
The record-holding largest object in the world is built of concrete. It is the Troll A marine platform, which extracts gas in the North Sea.
It is owned by Shell Oil and is the heaviest object ever transported by water from where it was constructed, on the coast, to its final location in the sea.
It was completed in 1991 and was moved by 10 ships over several days. It weighs 1,050,000 tons, and its construction used 245,000 cubic meters of concrete and approximately 100,000 tons of reinforced steel.
The Troll A in the North Sea is located 80 kilometers offshore northwest of Bergen, Norway. The platform is the largest ever transported, weighing 683,600 tons and standing 472 meters tall. The Troll A belongs to the gravity base foundations, meaning it rests on the seabed due to its weight. The construction of the platform cost $650 million at the time.
The Troll A platform is a milestone in engineering and has set several records in the Guinness Book. In 1996, it set the record as the largest oil platform in the world, a record later surpassed by the Petronius platform. In 2006, singer Katie Melua held a concert at its base, setting the record for the deepest underwater concert, 303 meters below sea level.
The Troll A platform has contributed to Norway's economic development, as the country is one of the world's largest exporters of natural gas. Additionally, the platform has helped reduce carbon dioxide emissions and improve air quality, as natural gas is a cleaner alternative compared to coal or diesel.
The technology used in the construction and operation of the Troll A platform has been revolutionary. Shell has developed technology to produce, liquefy, store, and offload gas onto floating liquefied natural gas carriers (FLNG) at sea. These advanced technologies allow access to remote natural gas fields and serve larger fields with various FLNG installations.
The environmental impact of the Troll A platform has been minimized thanks to directional drilling, which has played a crucial role in accessing the Troll field while simultaneously reducing environmental impact. Directional drilling tools provide real-time data to guide the drilling process, ensuring precise well placement.
In summary, the Troll A in the North Sea is a natural gas extraction platform owned by Shell that has contributed to Norway's economic development and helped reduce carbon dioxide emissions and improve air quality. The technology used in its construction and operation has been revolutionary and has minimized environmental impact.

💥What is underpinning in construction

A process of placing a new foundation under an existing one or strengthening an existing foundation is known as the underpinning of foundation. Underpinning may be required for many purposes.

Following are the purpose of the underpinning of foundation,
To strengthen the shallow foundation of an existing building when a building with the deep foundation is to be constructed adjoining it.
To strengthen the existing foundation which has settled and caused cracks in the wall.
To deepen the existing foundation ( resting on poor strata) so as to rest it on deeper soil strata of a higher bearing power.
To construct a basement in an existing building.

Types of Underpinning of foundation

Pit method.
Pile method.

1) Pit method:- On this method, the entire length of a foundation to be underpinned is divided into a section of 1.2 to 1.5m lengths. One section is taken up at a time. For each section, a hole is made in the wall, above the plinth level, and the needle is inserted in the hole.

The needle may be either of a stout timber or steel section. Bearing plates are placed above the needle to support the masonry above it. The needle is supported on either side of the wall on crib supports ( wooden blocks) and screw Jack’s. A foundation pit is then excavated up to the desired level and a new foundation is laid.

When the work of one section is over, work on next to next section is taken up, I,e,.., alternate section are underpinned in the first round, and then the remaining sections are taken up. If the wall to be underpinned is weak, taking shores may be provided. Similarly, the floor may also be supposed, if required.

If an interior strong column exists, or if the foundation is to be extended only to one side, cantilever needle beams may be used in the place of the central needle beam. Jack is placed between the column and the wall.

Following points should be noted in the pit method
The alternate section is taken up in the first round. The remaining intermediate sections are taken then taken up. only one section should be taken at the time.
If the wall is long, the work is started from the middle and is extended in both the direction.
If the new foundation is deeper, proper timbering of the foundation trench may be done.
Needle beams etc should be removed only when the new foundation has gained strength.
This is desirable to do the new foundation work in concrete.
A needle holes etc. should be closed in masonry using cement mortar.

2) Pile method:- On this method, piles are driven at regular intervals along both sides of the wall. Generally, borehole piles or under- reamed piles may be used. In this piles are connected by concrete or steel needles, penetrating through the wall.

These beams incidentally act as pile caps also. This method is very much useful in clayey soils, and also in water-logged areas. The existing foundation is very much relieved of the load.
