4 INSTALLATION OF TRANSPORTATION pipe FOR GAS, PETROLEUM AND DERIVATIVES PIPELINE INSERTION SYSTEM Following the philosophy of always presenting the ideal solution for any challenge faced in subsoil engineering, Brasfond developed and patented a new technology for pipeline insertion, with a piping support system and automated welding system. The PIPELINE INSERTION SYSTEM holds global patent US 8,727,666 B2. The ducts normally extend in large stretches with continuous lengths of up to 5 miles. They can also be installed along with the excavation of the tunnel. When there are tunnels with small sections (mini-tunnels), the piping is inserted without the need for further manpower. Advantages of the Technology Automated system that allows for pipe quality control and monitoring from any place; Vertical and horizontal tilt positioning control sensors; Insertion of continuous pipelines up to 5 miles for 30 pipeline, inside tunnels with large and small diameters (mini-tunnels); Insertion in Open Cut trenches; Adaptation of the pipelines to the tunnel geometry; Possibility of removing the pipeline from the tunnel for replacement of aging pipeline; Continuous insertion of pipeline sections up to 42 diameter; The metallic supports attached along the tunnel allow for proper support of the pipeline being inserted,as well as curves and deflections (deviations) that take place during the tunnel construction phase; In case of tunnels excavated using the Drill and Blast technique, the support attachment region can be adjusted prior to insertion by the application of mortar. 4 Brasfond - Oil & Gas

8 INSTALLATION OF TRANSPORTATION pipe FOR GAS, PETROLEUM AND DERIVATIVES EXECUTION OF DEEP SHAFTS Brasfond recently introduced Brazil to a new drilling technology for Deep Shafts called Blind Shaft. This method, as opposed to the Raise Boring process, executes the widening of the pilot hole from the surface, i.e., from top to bottom, which eliminates the previous existence of a tunnel or gallery in the far lower portion, providing a significant time-to-delivery reduction. Fast and safe, the Blind Shaft reaches depths greater than 800m and diameters of up to 8.00m, wide in a single pass. The use of the latest down-hole motors (Rotary Vertical Drilling System) for drilling the Pilot Hole provides the process with a unique capability to maintain the verticality of the hole, achieving results under 0.10% of vertical deviation. The drilling of the Shaft using the reverse circulation process (air-lift) only uses water as a drilling fluid, which eliminates environmental damage since the material from the excavation can be used as an aggregate or even disposed of in locations near the worksite. Methodology The first step for executing the work is the consolidation of the rocky mass surrounding the axis that will be drilled and high pressure injected with cement in order to reduce the faults or fractures of the rock so as to eliminate any efficiency loss in the reverse circulation (air-lift) process. The execution of the Shaft continues with the drilling of a Pilot Hole until reaching the projected depth. Then, this hole is widened to the desired width using special bits that are coupled to a rig with high torque and lifting capacity (350 tons). View of the Work Project 8 Brasfond - Oil & Gas

10 INSTALLATION OF TRANSPORTATION pipe FOR GAS, PETROLEUM AND DERIVATIVES MECHANIZED EXCAVATION OF TUNNELS WITH TBMs BTC, a company of the Brasfond Group, executes tunnel excavations in soil and rock for basic sanitation works (interceptors and trunk sewers), energy generation (adduction), Highway, Railway, or Subway tunnels, O&G market, and others. The reduction of delivery dates for the construction of tunnels by using the TBMs with their resulting cost savings begins a new phase of Brazilian civil construction. The building processes and techniques used previously, such as Drill and Blast, give way once and for all to the non-destructive mechanized process a clean process without harming or impacting the environment. The Tunnel Boring Machine method is used worldwide and has become mandatory in several European countries due to their numerous advantages, especially in regard to the safety and integrity of the workforce. Also, they make possible the implementation of tunnels in any type of lithology, whether soft rock or the hardest that exist in nature.

12 INSTALLATION OF TRANSPORTATION pipe FOR GAS, PETROLEUM AND DERIVATIVES LARGE DIAMETER HORIZONTAL DIRECTIONAL DRILLING (HDD) The Horizontal Directional Drilling (HDD) is the process where pipes or cables cross large areas (built or not) without the need for opening ditches, making it a non-destructive process. The main advantages of its use include the precision when executing the works and the low environmental impact. methodology The executive methodology of HDD is based on three main steps: 1. Execution of the pilot hole Detail of the perforation bit The pilot hole is executed using high pressure hydrostatic equipment with a drill bit that has a direction system monitored by electromagnetic sensors. During the drilling, bentonite mud is used to maintain stable perforation while the removal of the perforated material is done using reverse circulation. 2. Reaming Process Detail of the widening bit/reamer After executing the pilot hole, the pilot drill bit set is exchanged for a reamer that returns in the same hole in reverse, widening it until it reaches the desired diameter. The enlargement of the hole is done gradually, in steps. The bentonite mud is constantly pumped to reduce the friction and ensure the stability of the bore. Centralizers should be used in front, of the reamer, in order to ensure its alignment in the hole. 3. Column Installation swivel reamer Detail of the piping connection column The column to be pulled should be previously assembled on rollers in a free linear space that is equivalent to the distance being drilled. During this step a device called a swivel is used. The swivel is located between the drill rod and the product pipe. The swivel serves to avoid product pipe rotation during the pulling process. 12 Brasfond - Oil & Gas

14 SPECIAL OFFSHORE FOUNDATIONS FOR EXPLORATION PLATFORMS EXECUTION OF LARGE DIAMETER BORED PILES The Brasfond Group executes special foundations for ports, bridges, and offshore terminals using large diameter excavated piles, with lost or recovered metallic jackets, and offshore or onshore equipment. The use of this type of pile was widely adopted due to the facility and quickness during execution and its adaptability to different types of land, as well as the immediate recognition of the excavated material. The excavated piles can reach depths above 100 meters on both soil and rock. Executive methodology Each project that is developed requires specific solutions for proposed challenges, but the basic execution methodology for an offshore bored pile follows the order listed below: 1. Driving the metallic casing using a hydraulic or vibrating hammer; 2. Soil excavation with hydraulic rig that uses a reverse circulation system; 3. Cleaning the excavation with air-lift; 4. Installation of reinforcement cage; 5. Submerged concreting of the pile. 14 Brasfond - Oil & Gas
