Making safety second nature: Learning from Normal Work and Noble Peak

A strong safety culture should be built upon the successful everyday practices that are happening offshore.

For too long our industry has approached incident prevention from the perspective of “Safety-I” which focuses on analyzing failure, adverse events, and accidents after the fact. Human factors researchers suggest that safety critical industries should learn from everyday successful work in addition to incidents and failures. This is the definition of “Safety-II,” which focuses on studying normal and successful work, performance, and processes. Safety-II learns from everything happening in the system, from good to bad. This proactive approach encourages continuous learning and improvement, as compared to a reactive approach, which we believe cannot truly prevent future incidents.

Since 2022, Noble has been implementing Learning from Normal Work within the HSE department and on board several rigs in our fleet. Additionally, subject matter experts have taken the program externally to serve as an example to the industry, positioning us as leaders in preventative incident management.  

Safety-I

Learning based on failure, adverse events, and accidents after the fact.

Safety-II

Learning based on normal and successful work, performance, and processes.

The Learning from Normal Work concept emphasizes understanding and learning from everyday operations, not just from incidents.

The purpose of Learning from Normal Work is to address safety as not only a top-down process through formalized procedures but also as a bottom-up process where the frontline worker builds capacity and resilience into the work processes through the way they act, interact, and co-create the conditions of their work. Personnel are viewed as a solution, not a problem that requires control. 
We empower rig personnel to contribute to the entire system and have greater influence on how the company enhances onsite safety.

Noble’s pilot approach in Learning from Normal Work included three methods:

In 2024, Noble’s HSE department worked on defining the scope of Learning from Normal Work and how it integrates with other state-of-the-art safety concepts under the umbrella of Noble Peak, which is what defines Noble’s core safety policy. Noble Peak is an eclectic approach that integrates the best aspects from methods like Safety-II, Safety as Capacity, Safety Differently, Human and Organizational Performance (HOP), and Learning from Normal Work into our organization.

The three principles of Noble Peak are as follows:

Empower Our People

We recognize people as the solution 
and engage them as co-creators.

Reinforce What’s Working

We focus on what’s strong and
not what’s wrong.

Embrace Variability

We are inspired by new ideas 
and accept that there can be more than one correct way of doing things.

Learning from positive examples is foundational to our Learning from Normal Work program. During rig operations, positive work examples are observed by peers or leaders and documented for further exploration within learning teams. A Learning Team is an interactive tool intentionally designed to be “bottom up” for reflection and dialogue-based learning within a collective group. 

Noble is revisiting and adjusting tools that have been established and used for a long time to fit with the Learning from Normal Work framework. For example, transition to work meetings fit within the “Empower Our People” principle, which leverages team members’ capacity to plan, communicate, and act effectively. Stop work drills fit within the “Embrace Variability” principle, which encourages hearing and sharing ideas. 

We already recognize the positive effects of implementing Learning from Normal Work and Noble Mode on performance metrics and work culture.

“Safety-II focuses on learning from everyday successes to improve safety, rather than just analyzing failures. At Noble, this approach empowers workers and recognizes positive practices, making the system more resilient and safe.”

Thomas Koester Human Factors Specialist, Noble

We already recognize the positive effects of implementing Learning from Normal Work and Noble Peak on performance metrics and work culture. Crews feel appreciated when their contributions are acknowledged and are more willing to speak up during operations when necessary. When a crew member feels psychologically safe, they’re more willing to speak up or use Stop Work Authority after observing something that might be wrong. As a result, our systems become more resilient.

Instead, it thrives on trust, transparency and alignment with shared values and behaviors. Strong governance practices reinforce this commitment, enabling future projects and long-term value creation for stakeholders. While Alliance members remain committed to fair competition and full compliance with anti-trust laws, they collaborate closely on operations, leveraging each company’s strengths to drive efficiency. 

Through alliances, we sharpen our ability to listen, learn and improve all aspects of our business.

We believe that helping unlock future opportunities for the Wells Alliance Guyana, we will also unlock new possibilities for Noble.

Taking responsibility and accountability for outcomes is a hallmark of the collaboration. KPIs (key performance indicators) support the Alliance vision and include cost per day, cost per well and days per well, and members are incentivized to excel beyond stated performance goals. The long-term nature of the contract allows Alliance members to take a team- and goal-oriented approach to performance, with the objectives of removing waste, streamlining delivery, optimizing resources and continuously improving operations and HSE.

When the Alliance challenged drillers to cut drilling time for deepwater wells in half, Noble was able to study every step of the drilling process and think outside the box to develop solutions. We met the challenge and continue to identify repeatable processes that allow us to save time, reduce cost, enhance safety and potentially to cut emissions. Repeatability also allows the Alliance to plan and forecast more effectively. 

Wells Alliance Guyana Values:

Field trip to Noble drillship engages next-generation workforce

Students from the University of Texas experienced offshore drilling firsthand, gaining valuable insights into a high-tech, safety-focused industry.

A conversation at an industry conference led to a unique learning experience for petroleum engineering students from the University of Texas (UT) at Austin and for Noble.

In October 2024, students spent a day on the Noble Globetrotter II drillship, warm-stacked off of Port Fourchon, Louisiana. Seeing the equipment, drill floor and living areas firsthand opened their eyes to the high-tech, safety-focused world of offshore drilling and insights into daily life on the vessel and industry careers.

For Noble, hosting future engineering talent provided an opportunity to spark interest in offshore drilling careers and showcase the company’s commitment to innovation and safety. Following the visit, Noble extended onshore and offshore internship offers to several students inspired by what they saw and learned.  

19

students, including 12 women, with specific interest in the drilling industry participated in the field trip.

The idea for the field trip grew out of a conversation between a Noble Offshore Improvement Manager and a professor in the UT Austin Hildebrand Department of Petroleum and Geosystems Engineering at the 2024 IADC Advanced Rig Technology Conference. Both recognized the value of demonstrating that offshore drilling can be a fulfilling career choice.

The professor selected 19 students, including 12 women, from 100 applicants in his undergraduate drilling class, prioritizing those who expressed specific interest in the drilling industry.

The visit on Noble Globetrotter II started with Noble’s onboarding, including training on emergency procedures and PPE. The students observed the riser system, moonpool, BOP and other rig components and systems, and visited the drill floor to learn about the rig’s autotripping system. Because the rig was stacked, they had exclusive access to areas typically off-limits when the rig is operational.

“I hope the industry as a whole looks at something like this and sees how easily it can be done. We should also tap more into the potential of our crews by having them talk to prospective students who want to work in our industry. On the visit, they proved to be very effective ambassadors of our industry because of their authenticity.”

— Robert van Kuilenburg
Offshore Improvement Manager

As part of the living quarters tour, students received mock cabin assignments, ate in the galley, and spoke with crew members about their jobs and careers. The experience gave students a deeper appreciation of Noble’s efforts to supporting its workforce.

Noble continues to look for innovative ways to help us attract our next-generation workforce.

Barrier Management 2.0: Strengthening governance in critical incident risk management across the fleet

In 2024, Noble strengthened its barrier management by implementing digital tools and solutions that provide a real-time view of cumulative asset risks and enable thorough integration of barrier management’s technical, operational, and organizational components. 

As a leader in the offshore drilling industry, Noble takes risk management seriously. Daily rig operations involve high complexity and significant risks. While our crews are highly skilled in executing safe operations, catastrophic events – such as casualties, explosions, structural damage, collisions or major environmental incidents – can have severe consequences including loss of life and ecological impact.

Across the industry, barrier management establishes and provides the framework to maintain multiple independent barriers to reduce risk and safeguard life, assets, and the environment from Major Accident Hazards (MAHs). 

This framework is deeply embedded in Noble’s culture and aligns with our vision to be the leading offshore driller, recognized as the First Choice for employees, customers and investors. Both regulators and customers are increasingly emphasizing the need for a robust barrier management approach. 

In 2024, Noble continued to strengthen its barrier management by implementing high-level management digital tools and solutions that provide a real-time view of cumulative asset risks.

Following Noble and Maersk Drilling’s combination, we developed a Barrier Management Strategy to require multiple independent barriers are in place to control risks and prevent cascading failures. 

This strategy standardizes technical, procedural, and organizational barriers across all units, aligning with the expectations of tier-one customers and global regulatory requirements.

Building upon our industry-leading risk management practices, in 2024, Noble continued to strengthen its barrier management by implementing high-level management digital tools consisting of dashboards displaying leading indicators over time.

By visualizing all barrier-related tools, systems and data outputs, we have created robust barrier integrity dashboards for each rig. This empowers our teams to make informed decisions, enhancing safety and efficiency.

While external pressures drive the need for a robust barrier management strategy, we see it as more than a requirement – it is a fundamental commitment to our mission, our vision, and most importantly, the safety of our crews.

Noble’s commitment to developing future subsea engineers

For over a decade, Noble has been dedicated to cultivating the next generation of subsea engineers through its subsea development program.

This initiative equips engineers with the skills needed to maintain subsea well control equipment on Noble’s rigs. The program recruits trainees from within the company – including lower-level rig crew members recommended by rig managers, recent engineering graduates, and former military personnel. Over 18 to 24 months, trainees rotate between classroom instruction at Noble’s Houston training facility, visits to OEM partners, and hands-on experience during 28-day rotations on Noble’s rigs.

The curriculum covers a wide range of topics, including hydraulic systems, mechanical training, and BOP (Blowout Preventer) operations. Additionally, the program emphasizes communication, teamwork, safe work practices, and the policies and procedures essential for safe rig operations.

Carl Lyle, who oversees the Well Control Equipment Training and Development Program at Noble, explains:

“We identified a need for a structured training program for our subsea engineers, given the technical nature of the role. It’s challenging to provide comprehensive training solely on the rig, so we developed a program that includes extensive off-rig training. This approach has been instrumental in meeting our ongoing demand for qualified subsea engineers.“

Practical exercises are a key component of the program, offering trainees real-world scenario experience. During rig rotations, trainees are paired with experienced team leaders who mentor them in applying classroom knowledge. Buford Sullivent, a Senior Subsea Engineer at Noble, highlights the value of on-rig time, noting that certain equipment, like motion compensation systems, are easier to understand in operation.

Effective communication is another critical aspect of the training. Trainees learn to interact with different departments on a rig to resolve issues. Sullivent adds, “Understanding how to communicate with various departments is essential. When working on a problem, trainees need to know whom to contact and how to request information. Utilizing these communication channels is vital for rig operations.”

“In a classroom, you can learn about tensioners and crown-mounted compensators (CMCs) through pictures, diagrams, and videos, but seeing them in action is crucial. Experiencing the equipment in use, such as weighing up the drill string and adjusting pressures, is invaluable for trainees. It’s challenging to grasp all the training data until you witness everything working together on a ship out at sea,” Sullivent explains.

The program also offers a clear path to career advancement within the company. Upon graduation, trainees are assigned to a rig as assistant subsea engineers, receiving further mentorship from subsea supervisors. Typically, within two years, graduates are promoted to subsea engineer positions, with several advancing to senior roles.

“The best way to enhance safety is through properly trained personnel. Demonstrating the level of training and competency of our rig workers, especially those from this program, is crucial for our customers.

Many individuals working on our well control equipment or in the office have progressed through this program, advancing to subsea supervisors, superintendents, and even management and director positions. This progression showcases the quality of our training program,” Lyle concludes.

Preparing for the emerging offshore CCS market

Noble is at the forefront of advancing offshore carbon capture and storage (CCS), a critical component of a lower-carbon future.

In the coming decades, offshore CCS is expected to store 25-50% of the millions of tons of CO₂ captured from industrial sites. Noble is preparing to be the first-choice provider of safe, cost-effective and scalable operations in offshore carbon storage reservoirs.

We are a partner in multiple research and development projects advancing the technology and operational capabilities needed to safely inject industrial-scale volumes of CO₂ into offshore reservoirs. We are applying our learnings – along with our technology acumen and innovation capacity – to work toward industry standards for equipment and rigs to serve the emerging market for offshore CCS.  

First-choice provider of safe…

…cost-effective CCS solutions

Planning for industry standard certification 

As a participant in the Project Greensand consortium, Noble played a key role in the world’s first cross-border CO₂ value chain for offshore storage. Our Noble Resolve jackup rig was deployed for the first injection of CO₂, which was captured shoreside, transported across national borders, and injected offshore Denmark at the Nini platform. We have an exclusive first right to all drilling work involved in Project Greensand until the end of 2027.

Building on expertise gained through Project Greensand, Noble launched the industry’s first CO₂ rig technology qualification program in collaboration with DNV and BP. This initiative focuses on developing a CCS-enabled rig design for drilling and workover operations in CO₂-rich environments. 
The initial phase of the program, completed in 2023, included a full technology assessment, risk analysis, and equipment testing to address the unique challenges posed by CO₂ in well control events.  

Through this work, Noble established key design enhancements, including:

These findings form the foundation of the CO₂-certified rig project, which continues to align operators, OEMs, and regulators around the technical solutions necessary to enable safe and efficient CO₂ drilling operations. 

In June 2024, together with DNV and Endeavor Technologies, Noble conducted a CO₂ well drilling simulation to model the challenges of supercritical CO₂ downhole in various well control scenarios. The simulation was designed to help drillers, operators and others begin to plan for industry standard certification for CO₂-enabled drilling rigs. 

Electrical CO₂ Enabler is a crucial system to enable an offshore drilling unit to safely handle and operate in high purity CO₂ charged reservoirs.

To continue building on our offshore CCS knowledge, Noble joined the Project Green Light R&D initiative developing the first well control software designed specifically for CO₂ drilling operations. Led by eDrilling, the project aims to enhance drilling safety by simulating dynamic well control scenarios and mitigating risks where CO₂ plumes may interfere with well construction. Noble contributes operational expertise to this effort, reinforcing its focus on enabling safe and scalable offshore carbon storage.

Additionally, in 2025 Noble will participate in drilling a research well at the Petroleum Engineering Research, Training and Testing Lab at the Louisiana State University (LSU). This well will be used to study how CO₂ behaves throughout the wellbore as it transitions between different phases, while also providing a controlled environment to test materials and equipment under high-CO₂ conditions. 

As a participant in the Project Greensand consortium, the Noble Resolve jackup rig was deployed for the first injection of CO₂. The CO₂ was captured shoreside, transported across national borders, and injected offshore 
at Denmark’s Nini platform.

“Our dedication to innovation and safety in CO₂ drilling operations is unwavering. By developing and implementing advanced technologies, we are not only setting new industry standards but also paving the way for a sustainable future in offshore carbon storage.”

Jens Hedegaard Senior Manager Low Carbon Solutions, Noble

Looking ahead, Noble has identified several near-term North Sea CCS projects that align with its jackup fleet, requiring extensive CO₂ injection well drilling and legacy well workovers before 2030. Offshore CCS projects are also expanding in the U.S. Gulf Coast, South-east, and Mid-Atlantic regions, offering additional opportunities to apply Noble’s expertise. 

By leveraging existing assets and experience, we believe Noble is well positioned to support the growth of the offshore CCS market, aligning with its decarbonization strategy and dedication to enabling a more Sustainable Energy Future.

Noble’s deep dive into using green methanol in offshore operations

Integrating green methanol into offshore operations can reduce the environmental footprint and contribute to broader energy transition and decarbonization programs.

To reach decarbonization targets and comply with regulations aimed at reducing greenhouse gas (GHG) emissions, the offshore drilling industry must consider powering operations with low-carbon fuels instead of marine fuel oil, LNG and other conventional fuels. Using alternative low-carbon fuels, however, requires innovation and investment to retrofit existing assets and build new assets over time.

To understand the adaptations needed to operate an offshore drilling rig using an emerging low-carbon fuel, Noble relied on our 360-degree decarbonization model. In collaboration with a customer and a third-party design consultancy, Noble conducted a feasibility study of the safety, operational and feasibility aspects of upgrading a harsh environment jackup rig offshore Norway, using green methanol as a key component. 

Navigating the regulatory landscape

Our team started by meeting with stakeholders such as Class, Flag State authorities and local regulatory bodies to understand the regulatory landscape for the application of alternative fuels and if additional requirements would apply for offshore drilling units. In particular, we also needed to know if the green methanol rig concept would meet International Maritime Organization (IMO) expectations to reduce 20-30% of GHG emissions by 2030 to drive their 2050 net-zero scenario. All stakeholders agreed it would be feasible and that existing guidelines and regulations from Class and IMO would apply.

Assessing technical feasibility

Noble conducted an in-depth study of: 

We also assessed the impact of adding green fuel engines, tanks and related equipment on the rig’s variable deck load capacity and operations. 

The feasibility study concluded that it is possible to upgrade a rig to enable green methanol use, 
at a considerable investment, and that more progress is needed to attain a reliable supply of green methanol. Based on the study findings, Noble developed a conceptual design of the world’s first green methanol drilling rig.

Integrating green methanol into offshore operations can reduce a company’s environmental footprint and contribute to broader energy transition and decarbonization programs. Noble continues to apply our 360-degree decarbonization model to implement data and technical upgrades, partner with customers and operationalize solutions to achieve a Sustainable Energy Future.
