The Rota 3 project, which belongs to Petrobras, is underway and aims to specifically increase the flow of natural gas from the projects in operation in the pre-salt area of the Santos Basin.

The Rota 3 Gas Pipeline has a total length of approximately 355 km, with 307 km being the marine section, which was distributed as follows: 297 km referred to as ultra-deep, deep, and shallow sections, 10 km known as the ultra-shallow section, in addition to 48 km referring to the land section and, upon completion, will transport natural gas from the Pre-Salt Pole of the Santos Basin to the Petrochemical Complex of the State of Rio de Janeiro (Comperj) in Itaboraí, where the Natural Gas Processing Unit (UPGN Rota 3) is located.

The ultra-shallow section is under construction, but the arrival of the pipeline at the coast was completed in December 2019 and took place in the municipality of Maricá (RJ), more precisely at Jaconé beach. The land pipeline is nearing completion and is being implemented through the municipalities of Maricá and Itaboraí, until reaching the UPGN Rota 3.

Shore Approach

Some of its relevant parts were executed through the construction method known as HDD – Horizontal Directional Drilling. Horizontal Directional Drilling corresponds to a non-destructive method (NDM) of construction aimed at the installation, repair, and/or refurbishment of underground pipelines, ducts, and cables, utilizing techniques that can reduce or eliminate the need for excavations.

In this venture, DrillTec Drilling Services was subcontracted to carry out the HDD activities. This company is among the leaders in this segment in South America, specifically in Horizontal Directional Drilling projects for large lengths and diameters. It is also specialized in engineering solutions for the construction of ducts using non-destructive methods, utilizing HDD as an alternative for:

Shore Approach
Crossover of Streams, Rivers, Bays, and Mangroves
Crossings of Highways, Dams, Pipelines, Ridges, and Mountain Chains
Inclined directional drilling (SDD), aimed at interconnecting and/or revitalizing oil well production

Specifically in the Rota 3 Gas Pipeline, DrillTec executed the Horizontal Directional Drilling in the Shore Approach at Jaconé Beach, which consisted of the installation of 1,300 meters of a 24” pipeline through the drilled directional hole. It also carried out two other intersections in the land section.

For the GTR3 Consortium, responsible for the land section, it constructed the horizontal directional drilling for the crossing of the Caceribú Canal, with a length of 550 meters, where a 22” pipe was installed, completed on 31/08/2019, in the city of Itaboraí-RJ. In January 2020, it began the directional drilling for the Crossing of the Serra da Sapucaia, with a length of 750m, for the installation of a 22” pipe, completed on 01/04/2020.

Directional and Horizontal Drilling – Land Section

As part of its know-how, DrillTec also develops, plans, and executes crossings and short crossings using the technologies of Boring Machine and Hammer and TBM – Microtunneling.

Dissatisfied with seeing people sleeping on the street, a man named Ryan Donais started building small mobile homes so that homeless people can escape the cold, each equipped with a bed, running water, electricity, and heating.

Workers were opening a modern road in Dover when they found, 6 meters below the asphalt, a 3,500-year-old boat made of stitched oak and plant fibers.

A giant brown band visible from space, approximately 8,850 kilometers long, connected Africa to America in the Atlantic Ocean, and satellites revealed that it is neither land nor pollution, but the largest accumulation of seaweed in the world, which broke records in 2025.

Engineers want to carve through Africa with a giant canal to bring water from the world’s second-largest river to a dying lake on the edge of the Sahara Desert that has already lost 90% of its water.

Consumers eat six times more chicken than in the 1960s, global meat supply quadruples in 60 years, and FAO report reveals the invisible cost on the plate: livestock could drive 80% of the increase in agricultural emissions over the next decade.

Two 17-year-old Kenyans use coconut shells, corn cobs, and recycled materials to create an exhaust filter that reduces 93.3% of pollutant particles and wins an environmental award in Africa.

Motorcyclist sees excavator arriving at the edge of a river in Bosnia, calls neighbors in minutes and turns a hydroelectric project into a resistance lasting more than 10 years with five expired concessions.

There is oil below the oil that Brazil already extracts: Petrobras confirmed a new accumulation in the Búzios field, at a depth of 5,600 meters, in a zone below the reservoir already operating in the Santos Basin.

How much does it cost to build a rental building in Brazil in 2026 according to three real architectural projects ranging from a plot of just 36 square meters to a five-story building with twenty mini apartments?

How much do you need to earn to maintain Kwid, Polo, Corolla Cross, Haval H9, and Toyota SW4 on finance?

Even after China surpassed Russia in the volume of fertilizers sold to Brazil in 2025, for the first time in history, Russia remains a strategic partner and has signed a new agribusiness cooperation plan with Brasília focusing on the input.

Anvisa orders the recall of infant formula from the market after identifying serious irregularities and warns of health risks to infants and young children throughout Brazil.
