BOURBON 2017 Registration Document 13 GENERAL INTRODUCTION TO THE GROUP 2 Activities 3.3 SUBSEA SERVICES BOURBON offers its clients (oil operators or contractors) a range of resources for Inspection, Maintenance and Repair (IMR) and offshore structure construction activities. This range includes: 3 specialized vessels; 3 underwater Remote Operated Vehicule (ROV) which can perform operations at depths of up to 4,000 meters; 3 teams of engineers and technicians to provide solutions for the installation and maintenance of offshore platforms and subsea fields, in addition to the installation of equipment and cables for the offshore renewable energy business. Therefore, the service is contracted as follows: 3 bareboat vessel chartering; 3 by chartering vessel with associated crew, crane operator, catering services, and remote operated vehicule; 3 on a fixed-price basis for some installation contracts, with a performance commitment and limitation of liability. Chartering of Remote Operated Vehicule (ROV) are billed on per day basis and may include additional services such as positioning, survey services. Other services such as diving are subcontracted. Vessel and ROV chartering contracts involve an obligation to provide associated resource with limited liabilities and associated waiver of recourse. Engineering services are mostly provided on a lump sum basis and their liability extends to repeating the study in the event of a defect. Engineering studies are performed also for vessel charter usually limited to lifting calculation analysis in order to protect BOURBON asset and equipment integrity. For some contracts, particularly in the field of renewable energy, BOURBON provides fixed-price installation services subject to limitation of liability. 3.3.1 The Subsea fleet IMR vessels These are multipurpose vessels mainly used for ultra-deepwater Installation and Inspection, Maintenance and Repair (IMR) operations. They can also provide support for wind farms. BOURBON offers a wide range of vessels with cranes from 10 t to 250 t operating at depths of up to 3,000 m. Vessel are dynamically positioned with crane design to compensate vessel motions due to swell. Vessel have large deck and cargo capacity in addition to large accomodation capacity over 100 people. This range of vessels has been specially developed to meet the needs of oil operators during: 3 exploration for test wells; 3 contractors works for field development; 3 surface or subsea maintenance of offshore oil and gas fields; 3 emergency situations, including fire protection, surface and subsea anti-pollution, and personnel safety. The last generation Bourbon Evolution 800 vessels benefit from the support of and synergies with the BOURBON Marine Services activity, and the standardization of propulsion and communication equipment. Remote OperatedVehicles (ROV) Bourbon Subsea Services’ fleet of underwater robots (ROV) includes three main categories: 3 ROVs for light observation; 3 compact ROVs used for instrumental surveys and light construction work at depths of between 600 and 2,000 m; 3 ROVs of the UHD ( Ultra Heavy Duty) and HD (Heavy Duty) “Work Class” type, which enable crews to work and handle packages on all types of sites at depths of up to 4,000 m with great stability and precision. 3.3.2 Engineering and management services BOURBON also offers recognized IMR project engineering expertise for oil fields in operation (replacement of undersea connections, well heads, cables, narrow diameter pipelaying, etc.). This activity is complementary to the provision of vessels and ROV, enabling BOURBON to establish itself as a single provider for preparing and performing operations required on offshore fields. This service includes the complex project management and planning of procedures, as well as the provision of specialized personnel to manage the operations in question on board the vessels.
