The COVID-19 pandemic accelerated and potentiated the effects of solutions and problems known and previously faced in the offshore context, such as difficulties in scheduling boats and flights, long supply lead times and regulatory restrictions, intensifying challenges in planning and executing interventions. Aiming to contribute to better management of the operation of Offshore Units (UMs), it is proposed to investigate the main challenges and lessons learned in maintaining the integrity of platforms in situations of disruption of supply chains such as the one experienced due to COVID-19. In order to explore such challenges and lessons learned, we intend to investigate: (i) The definition and main indicators of integrity in the context of UMs, (ii) How has the literature dealt with disruption in supply chains? (iii) What are the critical factors for planning offshore integrity maintenance interventions? (iv) How maintaining the integrity of a UM is addressed in a company operating in Brazil and (v) How the disruption of the supply chain caused by COVID-19 affected the planning and execution of maintaining the integrity of a UM, its effects on the integrity of a UM and ways to minimise them. The investigation was carried out through a scoping review of the existing literature and through a case study of an organisation that produces oil in Brazil and called for notable points for observation by managers, academics and other interested parties, who can delve deeper into multidisciplinary working groups aspects that facilitate the management of possible new moments of disruption, whether in operations, contract management, strategy or supply management.
