Guest editorial Thirty years after Piper Alpha and the subsequent Cullen Inquiry into the disaster, which made 106 recommendations accepted by the oil and gas industry, safety remains a priority and a concern. In recent years, operators and the supply chain have worked in a relatively constrained, low-cost environment. The dramatic shift to producing hydrocarbons at lower cost, with fewer people, while transitioning to a more environmentally friendly and sustainable energy future is well under way and will undoubtedly have impacts long into the future. Business leaders and workers must take responsibility for increased investment in healthy, safe working practices and work closely with regulators globally to manage risk. Regulators remain vigilant toward major accident hazard management (MAHM). They are watching for gaps in safety-related skills that may potentially arise and lead to a higher incidence of major accidents in an industry cautiously stabilizing after the downturn. Knowledge loss, from the enforced mass departure of an aging and skilled workforce within the industry, is a concern as highlighted by a recent report from an industry/government working group in Norway, which reviewed offshore health, safety, and environmental (HSE) performance. It commented that although the level of HSE offshore Norway was high, safety challenges have risen in the past few years.1 Plugging the Skills and Knowledge Gap New research has revealed that recruitment is firmly back on the agenda after 4 years of consistent reductions, spurred by cost-efficiency measures. According to A Test of Resilience, DNV GL’s ninth annual report on the outlook for the oil and gas industry, more than a third (34%) of the 791 senior professionals surveyed expect to grow their workforce in 2019—more than three times as many respondents than 4 years ago (10%). Over a third (39%) also expect to increase the use of contractors this year. However, skills shortages and an aging workforce have resurfaced as a major concern. The issue takes joint second place as a perceived barrier to growth, alongside the oil price and the state of the global economy. Competitive pressure is viewed as the greatest challenge. The study also found a leap of 20 percentage points over the past 2 years in the number of respondents looking to increase or maintain investment in training and competence, up from 65% in 2017 to 88% for the year ahead.
