2017 REGISTRATION DOCUMENT

BOURBON 2017 Registration Document 91 MANAGEMENT REPORT Social and environmental information 3 The reasons for absence included in the calculation of absenteeism rate are: illness, accident, unauthorized absence, absence for industrial reasons (strike, etc.). Unpaid leave is also included for onshore personnel only. Accidentology indicators (LTIR, TRIR) are calculated using the OSHA’s (Occupational Safety and Health administration) benchmark. Accidents giving rise to disembarkation for medical reasons are not classified as LWC if the seafarer is able to resume work the day after the accident. Work-related accidents recognized by the competent national authorities are counted only if their characteristics are also confirmed according to the rules defined by the standards of the OCIMF. Formula for calculating hours worked by offshore personnel: for subsidiaries for which all activities of offshore personnel are entered in OCS HR: Number of days of working activity of offshore personnel * 24 hours of work per day. For the other subsidiaries having offshore personnel: number of days when the vessel is in the fleet* 24 hours of work per day x theoretical average number of persons on board x 105%. The theoretical average number of persons on board is defined in a table depending on the vessel sub-type and status. Formula for calculating the hours worked by onshore personnel: 8 hours of work per day x average workforce over the year x number of theoretical days worked. The number of theoretical days worked is defined in a table based on the legislation and collective agreements in force in each country where onshore personnel work. It excludes weekend days, holidays and annual leave. In terms of occupational illnesses, the scope is limited to the Group’s French subsidiaries, i.e ., 20% of the workforce at the end of the period. 6.4.4 Environmental indicators The environmental data, for the indicators relative to gas emissions (emissions of CO 2 , SO x and NOx) and energy consumption (Marine Gas Oil) concern respectively 392, 391 and 388 of the 392 vessels of the Marine Services and Subsea Services activities that operated in 2017 (1) . The impact of non-chartered vessels is not significant. The indicators on waste, the use of freshwater and used oil only cover Supply and Surfer vessels under 32 m. They do not cover the 178 Surfer vessels under 32 m whose overall impact is not significant. The indicator for the quantity of used oil incorporates 208 vessels following the exclusion of 6 vessels with unreliable data. The Group’s environmental performance has been followed on the basis of relevant indicators with regard to its activities. The indicators have been calculated on the following principles: 3 CO 2 : fuel consumption, with an applied mass coefficient of 3.206, in compliance with circular MEPC/47111 of the International Maritime Organization (OMI). Fuel consumption is reported using the Surfer Reporting Application (SRA) and the Operational Data Application (ODA) by seagoing personnel; 3 SO x emissions are calculated on the basis of fuel use and the average sulfur rate; 3 NO x emissions are calculated on the basis of engine rating, hours of machine operation, load factor and emission factor of each engine; 3 the fuel density is reported by crew or, failing this, estimated using the ratio 0.85 metric ton/m 3 . 6.4.5 Additional information on the application of the provisions of Article L. 225-102 of the French Commercial Code Given the specific nature of its business, BOURBON does not consider the following issues referred to in Article L. 225-102 of the French Commercial Code to be applicable in view of their irrelevance with the Group’s operations: consumer health and safety, use of raw materials, land use, noise pollution and food wastage. Furthermore, BOURBON does not disclose the electricity consumption of its offices outside France, as this is considered to be immaterial in comparison with its fleet’s fuel consumption. (1) 1 vessel had to be excluded from SO x emissions because it was not possible to make its data reliable this year and 4 vessels did not report information on NO x .
