Chairman’s Statement


Climate change represents a universal crisis for mankind. Carbon neutrality, therefore, serves our common interest. In September 2020, President Xi Jinping pledged at the UN General Assembly that China would hit peak carbon dioxide emissions before 2030 and achieve carbon neutrality by 2060. These goals have helped boost the global trends of sustainable development and green recovery in the post-COVID era.


As a responsible corporate, CNOOC Limited seeks the harmonious development of economy business and society, and human and nature. This past year, we united to fight COVID-19 with scientific effectiveness, and withstood the serious impact of low oil prices. While securing steady increase in energy supply and economic benefits, we promoted energy transition and green development, strengthened our efforts in environmental protection, energy conservation and emission reduction, carried out planning and emissions and carbon neutrality, and made new progress in relevant tasks.


Fighting the pandemic with concerted efforts, undertaking responsibility of CNOOC Limited. Just as jade needs to be polished, so one needs to go through trials and tribulations to be strong. In the great fight against the pandemic, CNOOC Limited insisted on putting the safety and health of our employees first. Through rapid, effective and people-oriented response and mobilization, and scientific and precise strategy, we built a strict line of defense to protect the lives and safety of our staff, ensured zero infection among Chinese employees, who worked onshore and offshore in China and abroad. Facing the same challenges together, we also offered support and help to others in need by proactively donating money and materials in the countries and regions in which we operate, and carried out international cooperation to fight the pandemic by exchanging and sharing first-hand experience and measures of pandemic prevention and control with the local governments and partners.


Pursuing the low-carbon strategy, driving energy transition. Alongside China’s goal of peak carbon dioxide emissions and carbon neutrality, CNOOC Limited supports the global trend of energy transition and green development to make active response to climate change. To practice the green and low carbon strategy, we improved the supply capacity of natural gas, cultivated a new energy industry, and accelerated the construction of “Green Oilfields” and “Green Factories”, which reflected our determination to tackle climate change and our commitment to global sustainable development. Firstly, we continued to increase the supply of clean energy and promote the development of key natural gas projects. The Bozhong 19-6 condensate gas field pilot project, which came onstream in 2020, and the Lingshui 17-2 gas field, which is scheduled to commence




production in 2021, will provide low-carbon and safe energy for the Bohai Rim region and Guangdong, Hong Kong and Hainan respectively. Secondly, we promoted the comprehensive utilization of marine energy by actively facilitation the construction of offshore wind power projects. As of the end of 2020, 57 turbines in our first offshore wind power project were connected to the grid to generate electricity.Thirdly, we adhered to the philosophy of “integration and coordination between development activities and environmental protection” and integrated sustainability into the whole value chain, by designing measures for management control at source, promoting digital and intelligent construction, and implementing the Bohai Bay onshore power project.


Cultivating safety culture, laying solid foundation for safe production and operation. In 2020, aiming to be a world leader in safety and environmental protection, CNOOC Limited upheld our core values of “safety first, environment paramount, people oriented and assetintegrated”, continued to implement our Health, Safety and Environment Management System Framework, heavily promoted a safety culture characterized by “people orientation, execution and intervention”, and enhanced the level of operational safety and emergency responses, thereby fully covering the integrity management of oil and gas fields domestic and abroad and delivering the best performance in production safety in nearly six years, which laid a solid foundation for production safety and high-quality development of the Company.


Adhering to people-oriented principle, actively assuming social responsibility. CNOOC Limited regards employees as the most valuable resource and asset. To achieve the common growth of the business and our staff, we adopt people-oriented approach and implement the strategy of “promoting corporate development with high-quality talent” by continually identifying and training new talents. We also care for the physical and mental health of employees, protect their rights and interests in various aspects, and strive to share our fruitful results with all employees. At the same time, as a responsible corporate, we uphold our commitment to contributing to the society and creating a harmonious environment. We join hands with stakeholders to make positive contributions to the public good by continuously providing maritime rescue services, carrying out poverty alleviation activities, facilitating community development and participating in voluntary services. To this end, we donated nearly RMB 93.30 million in 2020.


Looking back on 2020, we fought through adversities with hard work and diligence and eventually achieved fruitful results. In particular, the Company garnered numerous awards including the “Gold Award” in the 2020 ESG Corporate Awards by The Asset and “2020 All-Asia Executive Team Awards” by Institutional Investor. We rose to eighth in the Platts Top 250 Global Energy Company Rankings for 2020 and thirteenth in the Brand Finance Oil & Gas 50 in 2021.

Topic 1: Overcoming the COVID-19 Challenge in 2020




·           No coronavirus infection was reported among Chinese employees, at home, abroad, onshore and offshore


·           Domestic exploration, well drilling and production in China resumed in full by late February


·           All construction projects resumed normal operations in early March


·           90% of projects got underway ahead of schedule. Net production reached a record high


·           No major accidents were recorded


·           Coordinated promoted normalized epidemic prevention and control and the Company's operation 


Upon the outbreak of COVID-19, CNOOC Limited insisted on putting the safety and health of our employees first. We pressed ahead with work and production but practiced epidemic prevention and control. As a result, no Chinese employees at home or abroad, were infected with coronavirus in 2020.


Establishing Reliable Epidemic Prevention


Carrying out coordinated guidance and shouldering responsibility, CNOOC Limited worked tirelessly to establish an internal joint epidemic prevention and control system and mechanism, examined and developed various preventive measures for the pandemic at great length, and conducted full mobilization and all-round arrangements to ensure orderly anti-epidemic work.


Development of a Prevention and Control System


We swiftly set up a robust, effective, three-tier system:


lA leadership group arranged and mobilised our epidemic prevention and control


lSix teams, led by relevant departments, handled guidance, supplies, information, publicity, logistics and legal protection respectively




lSpecial teams at branch and subsidiary level took charge of organising and implementing prevention and control



Preventing and Controlling Infection


In the early stage of the pandemic, we controlled potential sources of infections and cut off transmission routes:


lWe immediately surveyed the travel routines of personnel, and placed at-risk employees under medical observation at home for 14 days


lWe conducted temperature checks at entrances to operation sites and workplaces. Any abnormalities were reported and handled promptly. At offshore operations with closed and densely-populated spaces, all staff were placed under 14-day medical observation


lTo protect domestic and overseas personnel, we controlled travel abroad


lWe used multimedia channels such as WeChat and Website to release official information in a timely manner and to promote scientific prevention information. We issued 50,000 reminder cards on epidemic prevention and control to employees


lAll branches and subsidiaries were required to report cases and relevant actions on a daily basis. These covered employees, contractors and family members


Caring for Staff


Acting on the principle of putting people and life first, we ensured staff care was in place:


lWe issued epidemic prevention supplies to all employees




lWe provided free, video-based outpatient services


lWe established an online platform for the overseas COVID-19 service center


We opened a free mental health hotline and provided counselling


Our branches and subsidiaries contributed funds and supplies for pandemic relief:


Tianjin branch donated RMB 2 million


Hainan branch donated RMB 820,000 supplies


China United Coalbed Methane Co., Ltd. donated RMB 1.225 million supplies


We made a further 14 donations for pandemic relief in 8 countries 


Developing Defenses Overseas


Amid the explosion of COVID-19 cases abroad, we also prioritized pandemic prevention and control overseas. We established an overseas leading group for pandemic prevention and control. Overseas units and teams acted swiftly to monitor the situations in their countries. Depending on regional risk levels, they implemented measures such as working from home and quarantine.


We established a 24-hour hotline for prevention, control and emergencies, established support teams to care for staff, set up a special fund for prevention and control, and expanded our Blue Force volunteer team. We increased logistics support, provided protective equipment, rotated personnel with extra service, implemented the “one-to-one” care project which helped overseas employees and their families to deal with material difficulties.


All overseas units developed contingency plans and communicated with International SOS to ensure that we could conduct cross-border rescues and protect personnel and production. This ensured our operations were unimpeded and business progressed.We shared our anti-pandemic experiences and good practices with contractors and partners in our areas of operation. Their ability to draw on these proved helpful when the pandemic peaked overseas.




Ryan M. Lance, CEO of ConocoPhillips said during an interview at Cambridge Energy Research Associates Week,


“We weathered the COVID-19 crisis and maintained operations without layoffs. In working with our partner, CNOOC, we came up with a protocol that said there was about a 14-day incubation period for the virus, send people offshore and have them work for 14 days and then the next group coming in would have to self-quarantine and isolate for 14 days. It really helped us work through the operational protocol that then was applied to the North Slope of Alaska, and to our offshore operations in Norway and elsewhere around the whole world." 


Resuming Work and Production


Amid the pandemic, we established a group to lead the work in a timely manner. We improved contingency plans, coordinated efforts to address the challenges faced by all units.


We planned transport routes and developed anti-pandemic transport measures. We strengthened communication with maritime departments to coordinate and dispatch vehicles, ships, helicopters and other means of transport by land, water and air for personnel working offshore, following a mandatory 14 days of medical observation.


Offshore shiftwork proceeded smoothly. Personnel were screened for symptoms and their temperatures were monitored. Ships and offshore platforms reported zero coronavirus infection.


Beyond China, we responded to the calls of the governments in the areas in which we operate. Our assets were protected and we provided communities with stable energy supplies.


By late February 2020, domestic exploration, development, well drilling in China had fully resumed. All domestic offshore oil and gas fields in production proceeded at normal rates. In early March, all construction projects resumed. 90% of new projects commenced ahead of schedule, and net production reached a record high. No major safety production accidents were reported.




Normalizing Prevention and Control


Facing the challenges of COVID-19, we shouldered heavy responsibility and delivered outstanding results. As the pandemic was brought under control in China, we aligned with the country’s policy of preventing imported cases and domestic relapse by embedding prevention and control in everyday production and business.


We have kept our goal to remain zero infections. Accordingly, we strengthened the duties of administrative divisions, units and individuals, drew up contingency plans, developed a robust network of normalized prevention and control, and put great effort into ensuring the supply of anti-pandemic materials to our employees.


Amid sporadic cluster outbreaks in China, we closely monitored abnormalities and changes in medium and high-risk areas, so as to be prepared to issue prompt warnings. We investigated outbreaks and handled them in accordance with our requirements and those of local governments until the risk abated.


The normalization of prevention and control system helped our business proceed smoothly. We helped combat the pandemic while pushing forward our own development.


Topic 2: Pursuing the Low-carbon Strategy, Driving Energy Transition


There is a global trend of energy transition and green development. Accordingly, our branches prepared implementation schemes. We aim to pursue a low-carbon strategy, increase the supply of clean energy and promote green development.


When the national goals of having CO2 emissions peak before 2030 and achieving carbon neutrality before 2060 were announced, we responded. We established working groups and a designated department to conduct research and formulate a roadmap.

- CNOOC Limited continued to screen the shortlist of suppliers by carrying out the open qualification review in written form and site visit in 2020. Besides, we organized internal and external experts to evaluate four suppliers on the spot and comprehensively conducted supplier assessment concerning qualification, the fulfillment of social responsibility, the level of risk control as well as HSE management


- CNOOC Limited conducted annual performance evaluations on internal suppliers including but not limited to product quality and the implementation of the HSE system. For suppliers failing the annual performance evaluation, their accessed categories would be eliminated from the supplier list.


Supplier Risk Management


- CNOOC Limited improved the risk control system in handling and announcement of violations of laws, rules and treaties for suppliers. 





- CNOOC Limited paid more attention to identifying supplier environment and social risk. In 2020, we invited the third-party to sort out and inspect the latest operation and credit risk of all internal suppliers. Meanwhile, we promptly eliminated those suppliers with the abnormal operation and high credit risk.


Requirements of Environment Protection and Energy Saving for Suppliers

We aim to achieve world-leading safety and environmental protection. We strictly abide by the Production Safety Law of the People’s Republic of China, Rules on Administration of Safety of Offshore Oil, Safety Rules for Offshore Fixed Platforms, and other relevant laws and regulations of the countries and regions in which we operate.


Referring to standards issued by organizations such as the International Association of Oil & Gas Producers, we have established an HSE management system known as CHSEMS. This includes 10 core elements such as leadership and responsibilities, along with 70 specific requirements. These set clear parameters for safety management.



We have three-tier management – headquarters, affiliated units and grassroots units – and an internal control mechanism for quality, health, safety and environmental (QHSE) protection consists of 23 administrative measures and 49 management procedures. We require affiliated and grassroots units to have their own QHSE systems and to undertake superior audits and special audits.




Risk analysis - Health, safety and security risks


Owing to the diversity of our operations, their locations and their technical complexity, we face risks including major accidents, natural disasters, social unrest, health problems and safety lapses. These may cause injury, death, environmental pollution and disruption of business, and hence negatively affect our reputation. Violations of laws and regulations may render us liable for significant costs, given that regulations regarding health, safety and security vary among countries and regions.


Measures: We have therefore established a health, safety and environment (HSE) management system, developed HSE audit tools and significantly improved our overseas HSE management. We have been tracking, analyzing, assessing and giving early warnings for overseas safety and security, to ensure our efficiency in emergencies.


With a sound mechanism of prediction and warning, 24-hour emergency watch and emergency resources support, we have strengthened equipment and facility integrity management and perfected well control and production safety management. We have also enhanced employees’ abilities to identify hidden dangers by offering intensive training and strengthening supervision and surveillance.


The Company's Safe Production Committee is our highest authority for quality, health, safety and environmental management. The Chairman serves as the director of the committee. In each situation, the committee sets up the position of safety director and decides matters including annual safety management goals, major accident investigations and treatments, and major hidden danger rectification measures. It also monitors implementation status and sets safe production rewards. The QHSE Department of CNOOC Limited is mainly responsible for the overall supervision and management of quality, health, safety and environmental protection.


Safety must permeate all of our business, production and operation. Our HSE accountability rules specify the responsibilities of all executives. In 2020, we published our Composition Instructions for Production Safety Accountabilities and Responsibilities for All Personnel to guide and standardize these aspects of our business. We have also worked closely with third-party agencies to train full-time and part-time audit personnel and staff, so as to improve production safety.


Our HSE system covers all subordinate units and third-party partners. And our HSE Administrative Measures for Contractors and the HSE Management Rules for Contractors have been complemented by the Notice on Further Strengthening Contractors’ Safety Management. The HSE system identifies contractors’ safety responsibilities and




professional qualification, site entry safety training, site supervision and performance appraisal. It uses a cumulative scoring that acknowledges accidents and dictates corresponding measures.


We took measures to enhance our HSE management in 2020:




• In a bid for zero fatalities, we set a goal of eliminating all major accidents and hidden dangers by means of supervision and audit.


• Based on our performance this year, we plan to release the HSE management goals according to the requirements of national and local authorities regarding 5 modules system operation, casualties, economic losses, environmental pollution and traffic accidents in China.

Employee Rights and Interests


We endeavor to create an open, transparent, equal, diverse, people-oriented environment that cares for employees. We protect the legitimate rights and interests of employees.


CNOOC Limited respects and supports the association freedom of our employees complying with the law. Guided by the Trade Union Law of the People’s Republic of China, we have established labor unions across different subsidiaries and branches, which have the responsibility and obligation to protect employees' legitimate rights and interests as well as to monitor the Company's practices. Labor unions also oversee all operational activities related to employee benefits and communicate with the Company on behalf of its members. We also maintain close communication with the legal department and labor unions to jointly guarantee employees' rights and interests.

We are also gradually establishing a distribution mechanism that matches the market mechanism. Our salary distribution implements multi-level incentives, rewarding researchers, technical experts and front-line workers, correlates with the quality of employees’ work and the value of their contribution and increases bonuses for extra production value and profit so as to match




employee income with the growth of the Company and enable employees to share in our business achievements.

Employee Development


We believe in mutual development with employees. Our training is designed to enable employees to realize their worth and achieve high-quality development for the company.


Talent Strategy


We strongly believe that the sustainability of our business depends on fostering talent, inspiring vitality and highlighting value.


To create an excellent employer brand, we seek out promising talent via campus recruitment, cooperation with schools and social recruitment. After formulating the Action Plan for Talent-Driven Strategy and Action Plan for “3+1” Project of Talent Cultivation, we commenced our 14th Five-Year Talent Development Plan.


As of 2020, we will select trainees for mentoring every three years. They will participate in key scientific research and technology studies. The years 2025, 2035 and 2050 will be crucial for us in realizing this talent-driven strategy. Our aim is to increase the proportion of mid and high-level talents such as academic, strategic and technical experts.


Cultivating Talent with the “3+1” Project





In June 2020, we implemented the Action Plan for the “3+1” Project of Expert Cultivation. Its aim was to create a competent management team, a professional expert team, an outstanding young management team, and an internationally competitive team.


−         We identified positions for outstanding young talents and stated that executives over 50, around 45 and around 40 should account or 50%, 30% and 20%, respectively. We formulated preferential policies for young people in promotions to achieve the goal of “double 50%”. This required that at least 50% of newly promoted executives be under 45 and at least 50% of newly promoted managers be around 40 in subordinate units each year.


−         The “3+1” project prioritized work experience. Newly appointed executives and young managers were expected to have worked for at least two years at grassroots level. This talent exchange between our headquarters and units ensured a high quality of candidates.


−         Breaking with the traditional idea of seniority-based promotion opened opportunities for young managers. We focused on their performance, to identify talents who made important contributions in key projects or performed excellently as leaders at lower levels.


A remarkable 718 young management talents were identified in 2020. Staff around the age of 40 now comprise more than 50% of newly promoted managers. 


A joint initiative with the China University of Petroleum, Beijing, cultivates talent. Internships and practical work opportunities help students acquire skills. Meanwhile, the university’s scientific research and tutoring in petroleum, artificial intelligence and big data helps to create a talent pool for our digital transformation and intelligent development. In 2020, we chose 20 new postgraduates for the three-year program.


We also collaborate with the university to identify professionals around the age of 35. Together we improve their creative thinking and practical abilities in oil and gas exploration, development and drilling.


The selection and training of experts greatly supported the development of the Company. In 2020, 38 talents were ranked as the fourth group of technical experts of the Company and 113 as the fifth group of subordinate units. We actively implemented the evaluation of vocational skills, encouraged the participation of first-line staff, and completed the evaluation on 1,855 employees for five professional skill levels across eight professional jobs, including primary workers, junior workers, senior workers, technicians, and senior technicians. By the end of 2020, the Company has attracted 4,620 senior workers or above and 1,080 technicians and senior technicians, accounting for 78.37% and 18.32% of total skilled workers in main jobs respectively. We conducted occupational qualification




reviews and certified 76 supervisors for their roles in exploration, downhole operation, drilling and completion.


CNOOC Technical Expert Wins Innovation Award


The highly prestigious National Innovation Award, approved by the Chinese government, was won by a CNOOC technical expert in 2020.

Responding to the impact of COVID-19, we made great efforts to add content to our Haixue online learning platform. This enabled staff to continue learning even when on-site training was unavailable. The resources ranged from professional skills and safety to an induction course for new employees.

Winner Scott Milligan, an intern mechanical technician on our Scott Platform in the North Sea, UK, promoted safety and teamwork and outshone 90 representatives of world-class energy companies.




Staff Care


As a people-oriented company, we believe that mutual development requires practical support. At home and overseas, we strictly observe regulations regarding leave. Besides statutory public holidays, we provide paid annual leave and family visit leave, and encourage staff to take vacations and rest. To migrant staff, we offer lump-sum payments, comprehensive subsidies. We offer transitional housing for single employees to continuously improve their sense of access, happiness and security in areas where available.


We endorse the trade union’s Warm Project, designed to build friendly labor relations. E-union coverage has been expanded so that employees can enjoy its services more flexibly and efficiently. In response to China's Healthy China initiative, we formulated CNOOC’s




Opinions on the Implementation of Healthy China Action. These aim to raise employees’ awareness of the benefits of health and psychological counselling.


We aim to build a home for employees, promote the integration of "association, station and home", and ensure that staff have access to warm help and mutual medical assistance.


Meanwhile, we have strengthened the construction of a home for employees and staff's nest in remote and hard areas as well as small, scattered and distant grassroots units. We also promoted the construction of facilities such as staff canteens, libraries, restrooms and common rooms.


We safeguard the rights and interests of female employees by undertaking “women’s contribution”, celebrating International Women’s Day, visiting female employees, and appealing to the professional pride and happiness of female employees.


In 2020, we endeavored to assist poor staff members. We used a special fund to help them and visited on important festival days so that they know the company cares about them.


In 2020, facing the COVID-19 outbreak, the company adheres to the people-oriented principle and puts the safety and health of employees as the top priority. We vigorously carried out health public welfare activities with free video-based COVID-19 outpatient services to minimize the impact of the pandemic on the mental health of the employees. We accordingly adjusted salary and welfare policies to ensure employees survive the pandemic. The company quarantined the offshore operation employees and offered subsidies, rewarded the employees who extended work on the sea, provided comp time and overtime pay for those who work on the land, and furthered protect pregnant women and lactating women during the pandemic.


In terms of medical security for employees, the company included the COVID-19 in the accident insurance coverage of the company and provided the full medical security through the supplementary medical insurance. What’s more, the company allowed the online claim settlement and drug purchase paid with supplementary medical insurance in 2020 and facilitated employees to seek medical treatment and purchase drugs at home and office through the digital claim settlement service.

In 2020, we built a rapid adjusting mechanism from “normal management” to “unconventional leadership”. We leveraged our resources and large-scale equipment and facilities for emergency rescue, and coordinated emergency responses with maritime departments and government agencies. This opened a green channel for land, sea and air rescue. The operating environment also benefitted from our technical research on information and communication, oil spill disposal, extreme weather rescues, and working conditions that safeguard personnel, property and ships.
