2017 REGISTRATION DOCUMENT

BOURBON 2017 Registration Document 90 MANAGEMENT REPORT 3 Social and environmental information 6.3.2 Management of resources BOURBON operates a fleet of modern vessels, for the most part equipped with diesel-electric propulsion technology that significantly reduces consumption and atmospheric emissions for offshore oil and gas marine services. A dedicated Fuel Management team is responsible for reporting, monitoring and analyzing the environmental data and has designed ways to feed data back to the crews and various land-based teams (HSE, operations, central functions). The implementation of dashboards makes it possible to monitor environmental indicators every month (Marine Gas Oil, lubricant oil, waste, emissions etc.). This enables the Group to adopt operational behavior which is increasingly responsible. Freshwater production is 61,148 m 3 (produced by 47 vessels using osmosis filter systems). The consumption of fresh water on board the vessels includes water for sanitary use as well as water intended for rinsing vessel equipment. It was 296,982 m 3 across the whole fleet excluding crew boats under 32 m. The consumption of bottled drinking water has not been reported, and neither has the indirect consumption of (electrical) energy by all the offices of the operational subsidiaries. Electricity consumption by offices in France is almost 800 MWh. 6.3.3 Pollution and waste management As far as the prevention of environmental risks is concerned, BOURBON applies national and international rules as outlined in section 5.2 of the management report. Special attention needs to be paid to polluting waste that is accidentally discharged into the sea. In 2017, BOURBON did not log a single major incident (1) of the kind that would cause environmental harm. The Bourbon Liberty 150 (15 vessels), Bourbon Liberty 300 (20 vessels), Bourbon Explorer 500 (10 vessels), Bourbon Evolution 800 (10 vessels), PX 105 (6 vessels) and P 105 (6 vessels) series meet the Oil Recovery classification. This classification indicates that these vessels can contain pollution and retrieve and store on board the hydrocarbons responsible for this pollution. BOURBON’s vessels are equipped with waste treatment systems that are compliant with the international regulations in force, in particular those of the IMO. The total volume of waste generated in 2017 was 13,947.96 m 3 . The volume of used (2) oil treated amounted to 3,773 m 3 across the fleet, excluding Crew Boats under 32 m. The waste generated and used oil discharged on land are processed by approved companies. The latest series of vessels delivered – namely the Bourbon Liberty 300 (20 vessels), Bourbon Explorer 500 (9 vessels), Bourbon Evolution (10 vessels), P 105 (5 vessels) and PX 105 (4 vessels) – satisfy the Cleanship classification requirements. These vessels have been designed and constructed to address the stringent requirements of protecting fuel reserves, treating waste water and general waste, limiting discharges into the water and the risk of water pollution as well as the impact on biodiversity. 6.4 NOTE ON SOCIAL AND ENVIRONMENTAL REPORTING METHODOLOGY 6.4.1 External standards The Group relies on Article 225 of the Grenelle II Act to report on and monitor its human resources, environmental and social indicators. 6.4.2 Tools used The Onsoft Computer Systems AS integrated information system was used to collect and process the social data for 2017 sent by the local entities. This information system was combined with the decision-making information system Business Intelligence, and the annual survey Human Resources - Crewing. The environmental data are obtained from the Surfer Reporting Application for Surfers below 32 m, while the Operational Data Application (ODA), a daily reporting tool launched in 2014, covers BOURBON’s fleet of supply vessels and Surfers above 32 m. 6.4.3 Social indicators BOURBON’s social reporting is carried out over the fiscal year (January to December). The scope of the social indicators includes subsidiaries controlled operationally by the Group and carrying employees, as well as three associate subsidiaries (Bourbon Gulf, Bourbon Marine Services Manila LTD, Sonasurf (Angola), Companhia de Serviços Maritimos, LDA). The other three associate subsidiaries (EPD Yangzhou, EPD Asia, Southern Transformer and Magnetics) are not included within the scope of the social indicators, as their core business is not the same as BOURBON’s. Regional and local establishment are determined according to the geographical assignment of employees and their nationality. The reporting of training hours covers 94% of the onshore workforce, excluding three entities (Naviera Bourbon Tamaulipas, Les Abeilles, Aries Marine), and 94% of the offshore workforce, excluding two subsidiaries (Naviera Bourbon Tamaulipas and Les Abeilles). In order to exclude weekends, which could be included in reports of offshore training courses, the following conservative approach was applied this year: training courses lasting less than 5 days were considered as calendar days and, for training courses of more than 5 days, only the business days were considered. This indicator will be made more reliable during the next fiscal year. The reporting of rates of absenteeism covers all directly-contracted onshore personnel (payroll), representing 86% of the onshore workforce, a priori without the exclusion of any subsidiary; nevertheless, as it was not possible to make the data for the Sonasurf entity reliable this year, it was excluded from the consolidated data, causing a reduction in coverage rates for this indicator, which is now 77%. The reporting of the absenteeism rate covers all directly contracted offshore personnel (excluding the subsidiaries Naviera Bourbon Tamaulipas and Les Abeilles) on a permanent contract (permanent contract payroll), i.e . 29% of offshore workforce. (1) Major incident: release of more than 500 liters of products into the sea. (2) The reported quantity of treated used oil does not include the quantity of used oil incinerated onboard.
