Human Capital


A custom-designed World-Wide Competency program, accredited by the International Association of Drilling Contractors (IADC), monitors offshore employees’ training history and continuously updates their progress. Additional employee development tools include an Operations Development Trainee Program, as well as workforce planning, succession management. Performance management processes and systems that help identify and assess highperforming and high-potential employees to ensure a focus on their coaching and development.

Diamond is proud of its reputation in the industry for having a world-class training program. Over 86% of Diamond’s workforce undergoes training and development each year.

Health & Safety

Diamond’s Health, Safety and Environmental Policy Statement: Caring for the lives of others and protecting the environment are responsibilities Diamond Offshore keeps at the forefront of everything it does.

Diamond believes that one of the most important things it can do for its employees and their families is maintain a working environment that promotes safety and personal security. The company uses the word “incident” rather than “accident,” because there is an inherent belief that accidents just happen and cannot be prevented. Diamond’s industry-leading health and safety program utilizes expert instructors to provide employees with custom-designed leadership development programs and best-in-class training related to the skills needed to work together to accomplish safe, efficient drilling operations on every well. The company also maintains an Ocean Technology Center that utilizes drilling simulation equipment to teach drilling practices, well control, crane operations and stability. Since 2015, Diamond has trained 1,149 professionals at its well control facility under the WellSharp standard, a set of comprehensive international drilling training standards developed by the industry.

Diamond is one of the few offshore drillers to maintain an in-house company-operated training facility, which allows the training to be customized DIAMOND OFFSHORE DRILLING for Diamond’s employees. Additionally, Diamond sources safety and technical training from third parties to ensure its crews are trained on the latest rig technology.

At the core of Diamond’s safety program is the Global Excellence Management System (GEMSTM), a fully-integrated risk, health, safety, environmental, quality, and asset management system. GEMS aligns with the applicable International Organization for Standardization (IOS) standards and complies with the requirements of the International Management Code for the Safe Operation of Ships and for Pollution Prevention (ISM Code). Diamond’s employees are empowered and encouraged to make any necessary decisions while on a drilling rig that would help ensure the health and safety of other employees, local communities and the environment where the drilling rig is operating.

In recent years, Diamond’s total recordable incident rates have declined to company-record lows.

Several safety initiatives have contributed to these declines, including:

  • A company-wide commitment to focus on safety;
  • A commitment to achieving Zero Incident Operations (ZIO);
  • The Diligent Observations Decisive Intervention (DODI) methodology, which helps eliminate undesired behaviors—commonly the cause of safety incidents—and fosters a positive and professional safety culture on rigs; and
  • A dedicated hand-safety committee, guided by Diamond’s Hands-Off Lifting Policy, works to eliminate hand injuries, which account for approximately half of all injuries in the offshore industry.

Diamond Offshore has also established health and safety processes and procedures in the evaluation and selection of suppliers, vendors and subcontractors. Diamond’s questionnaire must be filled out by any new vendor to ensure the vendor’s practices comply with Diamond’s standards.

Ethics & Integrity

Diamond’s Code of Business Conduct and Ethics reflects the company’s commitment to conducting business in accordance with the highest ethical standards and in compliance with all applicable laws and regulations. This commitment forms the foundation of the company’s global culture, which is shaped by its values and behaviors: Take Ownership, Go Beyond, Have Courage, Exercise Care and Win Together.

Diamond directs its people to know, follow and share training, resources and procedures designed to protect and respect employees, the company, its clients and the environment. Diamond also requires that those same high standards are followed by its vendors and suppliers across its supply chain.

Employees are encouraged to raise ethical, legal and human rights concerns, and Diamond offers multiple channels for them to do so, including anonymously. The company does not tolerate retaliation against anyone who reports a concern in good faith.


In accordance with Diamond’s Mission Statement and Health, Safety and Environmental Policy Statement, the company is committed to protecting the environment while conducting its operations consistent with the highest ethical standards and making a positive impact in the various communities in which it operates and in which its employees live.

Diamond is committed to minimizing the environmental impacts of its operations worldwide. The company not only complies with all applicable local, federal and international environmental requirements, but often goes above and beyond what’s required to minimize or eliminate environmental impacts. For example, the engines of Diamond’s rigs satisfy the requirements of MARPOL Annex VI (the applicable international emissions regulations.) Diamond also implemented a computerized planned maintenance system that automatically schedules the maintenance required to maintain its engines in top condition. This, in turn, minimizes Greenhouse Gas (GHG) emissions and the company’s carbon footprint. Diamond has also used low-sulfur fuel (at a concentration below 0.5% m/m) on its rigs for years, even though the regulations that require the use of such fuel do not go into effect until 2020. The use of low-sulfur fuel has substantially decreased the Sulfur Oxides (SOx) emissions from Diamond’s rigs.

Diamond promotes energy and resource conservation and efficiency as well as reduction of hazardous waste generation in various ways. Diamond procures environmentally-friendly products whenever technically feasible and available, particularly biodegradable products and products that do not pose harm to the marine environment. Diamond recycles the majority of the waste generated on its rigs, including but not limited to maintenance-related wastes such as oily wastes, paint, and batteries, as well as electronic wastes, which is recycled by fully licensed facilities.


Diamond is committed to making a positive impact in the communities in which it operates and in which its employees live. Some of the initiatives and programs that support this commitment include:

  • Hiring a substantial number of local employees in the various countries and communities in which it is active.
  • Sourcing goods and services locally, thereby positively impacting those economies including in the United States, U.K., Australia, Brazil and elsewhere.
  • Donating money and resources to various nonprofits and charities. Many employees participate in fundraising for children’s health and education programs. The company also encourages and supports employees volunteering at local food banks and hospitals and helping those in need in the wake of natural disasters.
  • Participating in team charity events, including the Diamond team that has participated for many years in a 150-mile bicycle ride from Houston to Austin benefiting the National Multiple Sclerosis Society. The company supports employees with the fundraising efforts through on-campus luncheons, bake sales and raffles with company-donated prizes. Past efforts have contributed to the team’s raising over $100,000 in donations to benefit MS research.
  • Participating in the annual Hess Houston Corporate Run benefiting Houston’s Memorial Park Conservancy and other nonprofit groups, including Houston First Responders.
