Skip to content For over 40 years, TSL Engenharia e Serviços has been executing critical operations with safety, responsibility, and compliance in the oil and gas, petrochemical, mining, steel, and energy sectors.
Our performance is supported by international certifications, registered technical responsibility, and strict compliance with Brazilian regulatory standards and international standards applicable to industrial and offshore operations.
Quality Management
Environmental Management
Occupational Health and Safety
TSL holds three ISO certifications, which are periodically audited by independent bodies:
It ensures that our operational processes are standardized, documented, and continuously improved. In practice, this means predictability and repeatability: the service performed today follows the same technical standard as the service performed ten years ago.
It establishes controls over the environmental impact of our operations. It applies directly to waste management, effluent treatment, and final disposal of materials generated in industrial cleanings.
International standard for occupational safety management. It underpins our protocols for high-risk activities: confined spaces, work at height, high pressure, and classified areas.
All TSL operations requiring engineering responsibility are overseen by professionals registered with CREA (Regional Council of Engineering and Agronomy), with the issuance of an ART (Technical Responsibility Annotation) when applicable.
The ART (Technical Responsibility Certificate) is the document that formalizes who is technically responsible for a project or service. It offers legal security to the client and proves that the work is being carried out under the supervision of a legally qualified professional.
This is especially relevant in services such as ultra-high pressure water jetting, equipment inerting, tank cleaning, and maintenance of critical industrial systems — activities that require risk analysis, technical planning, and specialized supervision.
TSL's operations comply with the regulatory standards of the Ministry of Labor applicable to each activity.
TSL maintains regular registration in the Federal Technical Registry (CTF), a mandatory registration with IBAMA for companies that carry out potentially polluting activities or use environmental resources.
Our waste management operations comply with the PNRS (National Solid Waste Policy), which establishes shared responsibility for the life cycle of waste and requires traceability from generation to environmentally sound final disposal.
We apply the specific sector resolutions according to the operation — among them CONAMA 273/2000 (fuel stations and systems), CONAMA 393/2007 (discharge of produced water on offshore platforms) and ANP Resolution 09/2007.
Operations on offshore platforms and vessels require an additional level of compliance. Our offshore teams meet the following requirements:
DNV is one of the world's leading certification and risk management organizations for the maritime and offshore sectors.
International Convention for the Prevention of Pollution from Ships. Directly applied to our tank cleaning services for ships and oil tankers.
Specific standard for safety and health on platforms. It integrates with NR-33, NR-35 and NR-20 in the offshore context.
Used in ship construction, repair, and maintenance activities.
The transportation of industrial waste and equipment is carried out in accordance with ANTT (National Agency for Land Transportation) and CONTRAN (National Traffic Council).
This covers the transportation of Class I (hazardous) and Class II waste, with proper documentation, licensed vehicles, drivers trained in handling hazardous materials, and traceability throughout the logistics chain — from collection at the industrial plant to the licensed treatment destination.
Major contractors in the oil and gas, petrochemical, and mining sectors require third-party companies to demonstrate technical expertise, valid certifications, and skilled teams. TSL has met these requirements for over 40 years.
