PETROBRAS is carrying out a study on USV FOR AUTONOMOUS AND REMOTE OFFSHORE OPERATIONS and its objective is to obtain information from companies mapped in the Supplier Register or in Market Research, to promote improvements in its supply and specification process.

Petrobras intends to contract the development of specific chemical inputs capable of improving the injection of produced water in secondary oil recovery processes. The application of this type of solution focuses on reducing interventions in injection wells (acidification), increasing or maintaining the injected volume and reducing the pressure differential in the wells during the reinjection process.

PETROBRAS is carrying out a study on DIVERLESS CONNECTION OF RIGID RISERS IN BELLMOUTHS and its objective is to obtain information from companies mapped in the Supplier Register or in Market Research, to promote improvements in its supply and specification process.

Petrobras has been facing several challenges for operational continuity and for the development of new projects - including high internal pressure. To overcome these challenges, it is needed to consider a series of structured actions.

PETROBRAS aims at gathering information on connectors applicable to subsea pipes to enable the construction and installation by a rig or a ship that does not need offshore welding facilities.

MAIN CHARACTERISTICS: 

• Connector qualified to operate for 27 years maintenance-free. 
• Can be disconnected and reassembled in a new location up to 4 (four) times.
• Redundant and Fatigue-qualified internal metal-to-metal seals, made of corrosion-resistant alloy (CRA) and external environmental metal-to-metal seal. Ideally, the internal seal should be located outside the main load path.
• Comply with or surpass international standards requirements:

DNV-ST-F201:2020 - Riser systems (if applicable);

DNV-ST-F101 Submarine pipeline systems (if applicable)

ISO 13628-7 Completion/workover riser systems

ISO 13679:2019 - Procedures for testing casing and tubing connections.

We are looking for four different pipe functions/scenarios:  

a. Water injection, e.g. NACE III + carbon steel on corrosion thickness and PIG campaign every 5 years; 

b. Dry gas injection (CO2 + methane with less than 40ppmv of water), e.g. NACE III alloy with corrosion thickness and PIG campaign every 5 years; 

c. Wet gas injection with up to 100% CO2, e.g. MLP with CRA liner;

d. Production (multiphase fluid that may contain high levels of water, H2S and CO2), e.g. MLP with CRA liner;

Request for Information - RFI to verify which companies in the market have inspection tools that allow assessing the structural condition of offshore composite pipelines like pipeline discontinuities, such as cracks, delaminations and pores.

Recent advances in the oil and gas exploration and production in ultra-deep water in Brazil have demanded efforts to develop and improve techniques and processes that optimize projects and field operations in the Brazilian´s industry in this sector.

Therefore, there is a need to develop alternative systems that are increasingly more efficient and reduce the CO2 emissions per unit of produced oil or natural gas, like the heat recovery for further power generation from the exhaust heat. Thus, Petrobras has intention to use Organic Rankine Cycle (ORC) in offshore platforms (FPSO) recovering energy from gas turbine exhaust flue gas. The purpose of this RFI is to gain a better understanding about the technology, its power generation potential (at least 3 MWe), footprint and weight of the system and its feasibility to be installed in FPSO.

Description of Issue

Digital twins, replicating the physical assets it represents, can significantly improve efficiency in the execution and operational phase. However, building robust and trustworthy digital twins that can be used for critical operational decisions, is a key industrial challenge. In the context of the subsea production system, Digital Twins of Risers Systems (flexible and rigid) are being devleoped by Petrobras. These Digital Twins require the availability of reliable data that can be used to assess the structural integrity of these systems.

Currently, Digital Twin technology can predict top tension and remaining service life of  risers by processing in real time digital twin models. However, there is no monitoring system to check the prediction provided by these models against real parameters such as top tension. Therefore, such parameter is one of the most important input for the Digital Twin analysis. This data is of great importance to assess the structural integrity of risers due to extreme and dynamic loads. Additionaly, specifically for flexible risers and its multi-layered structure, the structural integrity is also dependent on the number of broken tensile armour wires and annulus condition (i.e., dry or flooded).

Therefore, in order to have a robust Digital Twin system for risers system, it becomes very important to have a reliable monitoring system that is able to provide the aforementioned information. In that sense, the following prospection intends to understand better about the technological risks related to this development and the interest of the market on it.

This RFI aims to obtain information on the viability of the qualification, up to TRL 6 (API17Q), of a Subsea Chemical Storage and Injection System until June 2026.

Development of a Subsea Pig Launcher/Subsea Automated Pig Launcher (SPL/SAPL) for unprocessed natural gas.

Request for Information - RFI for market evaluation of solutions for subsea water-oil separation and reinjection systems, their system functions, technological maturity, operability, manufacturing capacity and other technical and management aspects.

Petrobras is performing is on the Swiveled Symmetrical Bending Stiffener, which aims to locally increase the rigidity of the flexible pipe to progressively reduce the curvature and, consequently, the stresses imposed on the pipeline, in order to meet specific demands for the installation of risers in deep waters. This bending stiffener absorbs the bending moments acting on the pipeline by bending a double polyurethane cone pivoted to a stationary structure. Therefore, there is a smooth transition between the tubular body of the pipeline and its termination.

Development of equipments and non-pumpable materials as a cement alternative on well annular barriers.   
The intended technological solution shall work as a well barrier element (WBE) and shall be installed together with mobile rock formations (with creep properties), to isolate the annulus of the well permanently.

Petrobras needs to detect cracks on external armour structures of flexible lines (without thermal insulation). We want to detect and measure Stress Corrosion Cracking. Petrobras needs to inspect these structures down to 2500 meters water depth, allowing for the scan of risers and flowlines every 1 meter length.

Petrobras intends to contract the development of a stimulating completion fluid capable of acting to remove damage from drilling, leaving a well without any damage or, preferably, slightly stimulated, so that a subsequent conventional stimulation operation is not necessary, reducing the need for a dedicated stimulation ship and its associated costs and risks.​​​​​
