Health, Safety, Environment and Security 2015 Annual Report

A Letter From Our CEO

Mike Fournier Dear Colleagues, Providing a safe working environment for Willbros employees is at the top of the Willbros Value Wheel. At times, it makes the job more complex, with processes that require additional resources and controls. However, beyond the moral imperative that makes safety a value rather than just a priority for us, our dedication to providing a sustainable, healthy and safe environment for our employees is vital to the quality of their employment with us – the quality of our service to our customers – and our ability to obtain work. As a responsible corporate citizen, we also need to keep sustainability in the forefront of our operational processes. In the long term, the Willbros safety culture also improves our operational abilities, and provides a dividend of reduced insurance premiums and the avoidance of incident costs. 2015 was a year of market challenges, with rapid growth of demand in our power distribution business and restructuring of our oil & gas business due to a weakness in market conditions. Safety performance historically suffers in changing conditions, but a pro-active Willbros team led the company, as a whole, to steady state safety performance relative to OSH recordable incident rates. A number of business units achieved industry leading performance for substantial portions of the year. This year we began the process of revamping the C2 (Culture of Accountability) effort and integrating it with Safety Leadership training. Our objective is to enhance our progress toward meeting the end goals of both processes, providing Willbros management with the tools for leadership accountability with respect to safety and operations. Willbros is involved in many environmental recycling efforts ongoing in Canada, UTD and at corporate offices. UTD and Canada are tracking and subsequently reducing equipment idle time. This will reduce the Willbros footprint for greenhouse gas emissions. The Canadian and Houston offices both offer a 9/80 work schedule, which reduces the number of vehicles on the road on Fridays, thereby affording a reduction in emissions as well. Along with our continued improvement in safety, we believe that more improvements in our environmental processes could be the next big differentiator between us and our competitors. Safety is a forward-thinking value that thrives within a leadership driven culture. Creative ideas, top down devotion to the safety of employees and the intertwining of safe concepts into operational processes all contribute to superior safety performance. We are confident that Willbros has the operational leadership, desire, and commitment to build on the changes made in 2015, learn from business unit successes, and show the business units that make up Willbros the way to safety performance leadership.

At Willbros, we believe that great safety is not a cost, but an investment with a high return across all Willbros Values and a key part of a high performance organization. We approach each and every safety incident with a mindset that it is preventable. We use six principles to guide our Value for safety and achieve our Vision for best-in-class safety performance:

1

Safety is about leadership and leadership isn’t about what’s in your title: it’s about what is in your character.

2

We will always strive to get better. When we fall short in our expectaduce that success elsewhere.

3

We will not compromise even in the face of great pressure on the time and discipline it takes to properly plan and execute our work in the safest way practical.

4

Stopping unsafe work isn’t a right given to us by someone else. Stopping unsafe work is an obligation that we hold ourselves and each other to.

5

Production done in the absence of safety will not be valued or rewarded. Period.

6

Great safety isn’t about policies and procedures. Great safety is about openness, honesty, involvement, communication and caring for one another.

HSE Management System

Key Elements

Key elements of the Willbros HSE Management System begin with a strategy that positions the HSE function as a performance-based model. Under this model, Corporate HSE and the Segments establish, implement and maintain appropriate systems, processes and procedures to reasonably prevent incidents from occurring and to limit the consequences of those that are not prevented. Corporate performance standards set a governance framework designed to both guide and oversee the HSE performance across Willbros with accountability for implementation of the standards squarely in the sphere of control of the Segments. These key elements and associated core management tools are integrated into a logical, interrelated, mutually reinforcing system focused on achieving continuously improving performance across the company.

Health and Safety

Performance Results Our primary goal is to promote an injury-free workplace by safeguarding the health and safety of our employees. Through evolution of our HSE management system we are able to successfully work toward our Key Result of a TRIR < 1. In 2015, we continued our success with a reduction in our TRIR with an annual result of .75. This is significantly below our goal of a company-wide TRIR of less than 1.00. We have also greatly reduced our injury costs over the last 5 years, most notably in 2015. This is a strong indication that continued efforts to focus on culture and behavior have made a significant impact in all of our operating areas.

Safety Focus -

Environmental In 2015, we continued to evaluate our impact to the environments in which we operate. Working with all business units, we collectively gather baseline data that will enable us to establish a benchmark from which to measure our environmental performance. Once a benchmark is established, development of green initiatives and sustainability concepts that are paramount in fostering a more environmentally conscious culture will be established. The success of these efforts will be accomplished through energy usage tracking, best management practices and conservation awareness programs that promote employee involvement.

Security While we continue to monitor both international and domestic security issues, North America is the current focus of our work. We are committed to providing a safe and secure work environment for our people, operations and assets.

Additional Areas of

Safety Focus HSE Assessments Assessment protocols are being restructured and developed in line with the revised HSE Management System. A data base is being developed to record Business Unit assessments for trending. The 2015 assessment schedule will be risk based within each of the segments. Our current plan is to assess business units within respective segments each quarter.

Workshops & Training change and ingrain cognitive safety concepts throughout the company. We employ external consultants to design internal modules to support the core safety principles we wish to instill.

HSE Communications Utilizing communication outlets such as semi-annual Directors’ Council meetings and bi-annual Managers’ Meetings, the HSE department takes Willbros. It is our priority to maintain a cohesive, united front throughout the enterprise.
