The recent European Norm 17975 addresses ‘grey zone’ energy-related risks during machine and pipeline interventions and proposes a task based framework for safe and efficient work. The norm can further increase the safety and efficiency of Lockout/Tagout programmes in a wide range of industries

A task based safety framework

10%-15% of fatal workplace accidents in Europe’s industries are related to maintenance operations according to data from the European Agency for Safety and Health at Work. Many of these result from underestimating risks involved in specific tasks such as machine greasing, sensor adjustment or a quick cleaning that are not always seen as ‘maintenance activities’. They are kept outside the scope of Lockout/Tagout programmes even though workers are exposed to similar risks. European Norm (EN) 17975 addresses these grey zone risks by using task based risk analyses as a starting point.

“EN 17975 does not require an energy zero state for every machine or pipeline during every intervention”, said Mustafa Ekseri, EMEA Safety Engineer at Brady Corporation, a supplier of quality Lockout/Tagout solutions. “Not having to halt an entire production line for every intervention can save valuable time - if it is possible in a safe way. To achieve this, EN 17975 proposes a layered approach based on risks related to specific tasks on specific machines and pipes. These risks are to be highlighted in a risk analysis. In absence of a risk analysis, machine zero energy states remain the safety standard. In that sense, EN 17975 builds on ISO 14118 by providing more options for compliance with European workplace safety legislation. Impacted activities can be defined using EN 17007 and EN 13306 and are also listed in EN 17975.”

Risk analysis guidance

With machine and pipe intervention safety hinging on identified risks, industries will need thorough task-based risk analyses. Guidance can be found in other standards. “ISO 12100, primarily intended for machinebuilders to take into account their customers’ workplace safety, can be used as a basis for machine intervention risk analyses. ISO 31000 provides guidelines for managing risk in general, including 8 core principles, a framework and a process.”

“EN 17975 proposes 6 steps to analyse the risk in any machine intervention task, starting with the identification of the task, all the way to a feedback loop for continuous improvement. That includes a thorough energy source inventory and identification. The standard also requires a risk analysis update before applying Standard Operating Procedures, and during maintenance activities. In addition, EN 17975 advocates clearly identified degraded situations that may deviate from the standard risk assessment.”

Task-based isolation

EN 17975 uses a task based risk approach that was captured earlier in the French norm X60-400. Based on a task risk analysis, the European Norm proposes four types of risk control processes:

• Neutralisation: a process that, through design of the control systems, shuts down an item of equipment so that a list of predetermined tasks can be conducted in safety.

• Standard isolation: a process that results in the removal – by locking in position a single or double isolating device – of all energies & fluids where the presence, accidental retention, unexpected appearance does not have hazardous consequences for workers, the environment, and items.

• Reinforced isolation: a process that results in the removal – by separation or by a combination of isolating and opening devices (e.g. valve, tap, etc.) – of all energies & fluids where the presence, accidental retention, unintended appearance does not have hazardous consequences for workers, the environment, and items.

• Specific provisions: a process that results in the implementation of organisational or technical measures enabling observation, diagnostics, testing activities and work on settings for the item in service to be carried out safely, with energies & fluids present.

“All four risk control processes require an inventory of energies and fluids per machine with their effects on people, property and the environment, a mapping of the isolating devices and an identification sheet of energies, fluids, components and lockout devices. It also requires a shared risk assessment grid and process. EN 17975 describes the aim, application conditions, type of activities and other relevant factors for each of the 4 risk control processes.”

Lockout/Tagout guidance

Complying with EN 17975 requires a human, organisational and technical approach, all of which are outlined in the norm.

EN 17975 identifies 9 steps to carry out reinforced and standard isolations by Lockout/Tagout of energies and fluids. Steps involve separation of energies and fluids, isolation, lock out, tagout, identification, dispersion of energies, check, contain and inspect. “The ‘check’ step in EN17975 is already widely known in the industry as the ‘Tryout’ in Lockout/Tagout/Tryout or LoToTo. It is a vital step to help make sure that measures are implemented correctly and that they are still effective.”

“Brady safety engineers can help industries implement isolations by writing machine- and task specific lockout procedures. These can include all 9 steps from EN 17975, and they must be based on company task risk assessments. In addition, we can offer the right Lockout/Tagout tools for procedure compliance, set up a hands-on demo by locking out a specific machine, and provide training to relevant employees. Alternatively, a gap analysis can be made that identifies steps to be taken from the current state to arrive at compliant, best practice Lockout/Tagout.”

Impact on existing safety programmes

EN 17975 is not a legal requirement. “The standard however considerably facilitates compliance with EU workplace safety legislation. It sets a clear expectation for any machine intervention: if no risk analysis for the task is available, a machine zero energy state is required.”

“Because many safety programmes already involve complete machine isolation from every energy source, for every task, it is likely that the new norm will impact existing Lockout/Tagout-programmes. Based on the risk analysis, machine zero energy states may not be needed for every type of intervention.”

“Adversely, some tasks that were considered ‘small and safe’ may unveil more risk after a thorough risk analysis. This means a single machine could have several Lockout/Tagout procedures. The right procedure can be included with, or communicated via a QR-code on a work permit for example.”

“Some forms of automated safety may not be sufficient for every task without an underlying risk analysis. Take a safety cage for example, equipped with sensors that deactivate moving machine parts the moment someone enters the cage. Do these nullify any residual energy that may pose a risk? Is gravitational, and other potential energy taken into account? The goal of EN 17975 is to prevent accidents, and to avoid a false sense of safety that does not provide any real protection.”

With the European Norm 17975, industries in Europe can now rely on a common standard for compliance with EU and national safety legislation that involve risk control processes of energies and fluids in maintenance activities.

Energy data and intelligence provider, TGS, has partnered with Egyptian Natural Gas Holding Company (EGAS), to initiate a large-scale 2D seismic reimaging campaign, the EGY-2DRE2026 project 

The survey will span across 34,000 kms offshore Egypt, which will be further integrated to the GeoStreamer 2016, 2018 and 2023 surveys. The compilation will comprise other available conventional 2D data as well, building single and consistent regional framework for interested operators to refer to across the offshore basins. The vast and insightful dataset will be fed into an advanced velocity model building and pre-stack depth migration workflow, including TGS' proprietary DM-eFWI technology, to generate credible images of pre-, intra- and post-Messinian salt intervals in high definition. 

The reimaged dataset that spans offshore Nile Delta, Herodotus Basin, and wider Eastern Mediterranean Basin will support clients to better resolve these intervals, giving a sharper, basin-wide structural framework to support prospect identification and maturation. This will play a significant role in decision making for operators to channelise exploration budgets in the right direction ahead of upcoming licensing rounds.

To support resource development, TGS has lately been taking up region-specific projects in Africa that aligns with a rising global demand for basin-wide reimaging and data integration across frontier and mature basins globally.

Final products for a priority subset of 2D lines are scheduled for delivery in Q2 2027, with the remaining full project scheduled for completion in Q1 2028.

"EGY-2DRE2026 will give our customers a modern, regionally consistent view of a basin that has historically been difficult to image beneath its complex Messinian section," said David Hajovsky, Executive Vice President, Multi-Client at TGS. "By combining our latest imaging technology with the depth and breadth of our existing coverage, we're able to de-risk exploration decisions and support our customers as they evaluate future opportunities in this highly prospective part of the Egyptian offshore."

The project is supported by industry funding.

Emerson has launched the TESCOM RC-X motorised injection rate control valve, which helps offshore refineries achieve accurate, repeatable chemical injection, reducing chemical waste, downtime and overall operating costs

Flow assurance is critical for offshore production facilities, especially as the industry moves to deeper water, longer tiebacks, deeper wells and higher temperature and pressure reservoirs, where conditions such as hydration, corrosion or the buildup of wax, asphaltene, scale and emulsion can restrict flow.

Chemical treatment can help mitigate these blockages, but there are dangers with over or under injection of chemicals. Over injection increases chemical consumption and resulting costs as well as additional field trips to replenish chemical storage tanks. It can also adversely impact downstream processing or treatment programmes and result in contamination penalties. Under injection can be ineffective, risking mechanical integrity and production output.

“Proper chemical dosing in deepwater and high-pressure/high-temperature refining environments can prevent blockages and flow instability, helping to ensure optimum fluid behaviour, protect asset integrity and stimulate production,” said Julia Villa, product marketing manager with Emerson´s fluid and motion control business, noting the TESCOM RC-X control valves enable accurate dosing that reduces downtime and chemical waste associated with over injection.

The value is specifically designed to work with Micro Motion Coriolis flow meters in offshore chemical injection processes, which deliver reliable flow measurement for liquids, gas or slurries.

Product features

• Precise flow assurance - With a short-stroke design (less than 1/8 of an inch), TESCOM RC-X control valves are accurate up to 15,000 pounds per square inch (psi) and offer ultra-low flow rates of 0.02-500 liters per hour and repeatable function with 4-20 milliampere (mA) control
• Electric actuation eliminates air requirements, an advantage when compressed air is unavailable or unreliable.
• Available in medium- and high-pressure models
• Lightweight and compact
• Fewer moving parts than comparable products, reducing risk of mechanical failure over time, performing more consistently and requiring less maintenance.
• Explosion-proof, waterproof (IP67-rated) and corrosion resistant (compliant to NACE MR0175).

The giant Ntorya gas field development in Tanzania is anticipated to deliver vital domestic energy supplies, alleviate local energy poverty, and drive long-term industrial and economic growth for the country

Tanzanian government authorities have recognised the urgency of the project's advancement and to make sure there is no delay, an optimised timetable has been established in consultation with the joint venture partners involved in the field's development. Designed with an aim to achieve first gas production by December, the packed schedule includes critical well workovers, testing, and accelerated drilling. Fully funded field operations and pipeline infrastructure integration will prepare the site for production generation.

Aminex has reached an agreement on the sequencing and implementation of the Ntorya gas development following a meeting convened by the Tanzanian Ministry of Energy

Key stakeholders convene

Representatives of the Ministry of Energy, the Petroleum Upstream Regulatory Authority (PURA), the Tanzania Petroleum Development Corporation (TPDC), ARA Petroleum Tanzania Limited (APT), the operator of the Ruvuma PSA, and Aminex's wholly owned subsidiary, Ndovu Resources Limited (Ndovu) were present at the meeting.

While the government did not approve the operator's proposal to extend and delay the project timetable, it did confirm a revised implementation schedule with all the parties involved. This schedule comprises workover of the Ntorya-1 well (NT-1) in October, the testing of the Ntorya-2 well (NT-2) in November and the drilling of a newly planned NT-Central well (NT-C) in December.

First gas from NT-1 and NT-2 is targeted for December. Drilling of the Chikumbi-1 well (CH-1) is to proceed after NT-C is drilled. Following the change of management at ARA Petroleum LLC and a technical reappraisal of the Ntorya project, APT had proposed bringing forward NT-C, previously planned as a development well for a later phase of field development, in place of CH-1, with the drilling of CH-1 deferred. The revised implementation schedule plans to drill the NT-C first, followed by the drilling of CH-1.

It was also confirmed at the meeting that the Ntorya to Madimba pipeline will be completed in time to receive first gas from the Ntorya field in December 2026.

APT confirmed to the parties that it had all necessary funds to carry out the revised programme for the development of the Ntorya field.

The parties agreed that APT should execute the planned activities in accordance with the revised implementation schedule and without unnecessary delay. The revised programme will now be progressed through the formal Joint Venture approval process in accordance with the Joint Operating Agreement.

Economic impact of the project

Charles Santos, executive chairman of Aminex, said, "I would like to thank Dr James Mataragio, Permanent Secretary for Petroleum at the Ministry of Energy, for convening the meeting last week and for the constructive approach taken by all parties. Our focus now is on working together to implement the agreed programme and deliver first gas without further delay.

"The revised implementation programme establishes clear near-term operational milestones, targets first gas for December 2026 and provides for the drilling of a newly planned well, NT-Central, while ensuring that the CH-1 well is also drilled.

"Together, these activities form just the beginning of the development of the giant Ntorya field which is expected to deliver large volumes of gas supplies to Tanzanians, helping alleviate energy poverty, boost industrial development and fuel Tanzania's economic growth."

In line with Nigeria's strategy to expand reach in export market, the Nigerian National Petroleum Company Limited has globally released its new crude grade – Cawthorne 

With an API gravity of 36.4 that denotes the light and sweet kind, the Cawthorne crude rules global market demand because of its unmatched petrol and diesel yields. Comparable to Bonny Light, Cawthorne crude blend is the latest from Nigeria’s basket of crude grades, building on recent additions such as Nembe and Utapate. 

The consistent market launches come from optimised production, helping Nigeria to solidify its base in the export market with diverse offerings. The Cawthorne Floating Storage and Offloading (FSO) vessel, which is strategically positioned offshore Bonny, Rivers State for enhanced energy security and operational efficiency in easy crude evacuation from OML18, comprised the maiden 950,000 barrels cargo for export. Loaded on an MT Eburones vessel, it headed to the Netherlands, and unto the global market. 

As Nigeria aims to attain crude production of three million barrels per day and gas output to 12 billion cubic feet per day by 2030, the international launch of Cawthorne will unlock value from its asset base and deepen market competitiveness.

“This milestone reflects the direction we have set for NNPC Limited—one anchored on execution, partnership, and value creation. We are moving decisively from resource potential to resource monetisation, ensuring that every asset delivers measurable commercial outcomes.

"The successful export of the Cawthorne crude grade is not an isolated achievement; it is part of a broader, deliberate strategy to grow production, deepen market relevance, and strengthen Nigeria’s position as a reliable global energy supplier. We remain firmly focused on delivering sustainable growth in line with national objectives and global market expectations,” said Bashir Bayo Ojulari, Group Chief Executive Officer of NNPC Ltd, as he acknowledged President Bola Ahmed Tinubu’s leadership and OML 18 partners' strong collaboration in achieving the milestone. 

Technological innovation, strategic partnerships, and operational discipline will remain central to NNPC Limited's vision as the organisation works towards value creation from Nigeria's vast hydrocarbons resources.
