2015 RESULTS

Since its launch in 2012, the "Safety Takes me Home" campaign has already produced significant results in terms of occupational safety, which remains the first pillar of operational excellence touted by BOURBON. Since September 2015, the third part of this c a m p a i g n , a i m e d at reducing - if not eliminating - the risks of incidents, has been deployed at sea and on land alike.

The kit developed for this third season, and distributed in 4 languages (French, English, Portuguese, and Spanish) deals with all issues related to occupational safety. It places special emphasis on safety tools and handling pressurized equipment, a common practice on our vessels. Never acquired indefinitely, the right reflexes, best practices, compliance with procedures, and

sharing knowledge among employees are still the best assets for improving our indicators and getting toward "zero incidents." Let's never forget that safety issues are a part of the elements to keep in mind at all times and that a good safety culture within an industrial company like BOURBON is acquired and is maintained only on one condition: that it is worked on continuously.

Deployment of the campaign in AngolaAt Sonasurf, the "Safety Takes Me Home" 3 campaign was deployed in bases and on vessels starting in December 2015.“Crew members are starting to get used to it, they are interested," explains Albano Fernandes, Managing Director of Sonasurf. Angolan deck seafarers, for example, "understand that it is a question of their own safety and apply the procedures set up by corporate even more easily since this campaign reinforces the previous campaigns", says Albano Fernandes.

Base managers and vessel captains received t-shirts in the colors of the campaign, and packs with different communications materials that enabled them to establish a dialog with their crews during specially dedicated days. Since its launch three months ago, the campaign has resulted in a significant drop in accidents.

SAFETY TAKES ME HOME:AN EFFICIENT SAFETY CAMPAIGN

THE BOURBON LIBERTY 207 IN HIGH PERFORMANCE MODE!

6 00 a n c h o r ra isi n gs peformed during one pipe-laying operation in Mexico, then 900 more off Ivory Coast: the AHTS Bourbon Liberty 207 flawlessly carried out these missions, so demanding for seafarers and equipment alike.

October 21, 2015, 1600 hours: BOURBON's Bourbon Liberty

207 begins a pipe-laying operation over the Lakach oil & gas field. Two pipelines, each measuring 38 km, must be laid at a depth of 20 to 50 m of water. “It's the first offshore continental development project in Mexico” explains Rémi Xiberras, captain of the vessel, one of 2 AHTS vessels mobilized for the mission. Its role? Advancing the barge, the Castoro 10 (from the company, Saipem), tasked with welding the pieces of pipe together one by one. “In concrete terms, this consists of raising the 8 anchors connected to the barge, then repositioning them a bit further along, to move the vessel forward as the pipe sections are welded together” the captain explains. 7.4 km of pipes were laid, and 600 anchor raises were performed.

A few months earlier, the crew of the same vessel had carried out another so-called papillonage mission, an operation in which an anchor handling tug supply (AHTS) vessel continuously accompanies a barge specializing in laying pipeline on the sea bottom, within a defined corridor. For 76 days, the Bourbon Liberty will handle 14 ton anchors nearly 900 times. "A papillonnage mission carried out by the Bourbon Liberty alone, while it is not unusual for this type of mission to be performed by 2 vessels…" the captain concludes.

2015 HIGHLIGHTS

1 Adjusted data derived from internal reports (IFRS8)2 Variation 2015/2014

BOURBON ARCTIC: CONQUERING NEW TERRITORIESThis AHTS (Anchor Handling Tug Supply) vessel, delivered in 2016 by the Vard shipyard, was specifically designed to operate in arctic areas and especially in very deep water offshore, where we know that there is a huge potential for development. It has just performed its very first anchor handling mission on the Fosen field, in the central part of the North Sea.

The Bourbon Arctic is a powerful anchor handling tug supply vessel designed specifically to operate in remote regions around the world. Capable of operating in the most complex environments, it features a maximum bollard pull of 307 tons, and 193 tons in diesel-electric mode. Its winch and storage capacities probably have no equivalent on the market today. Thanks to its exceptional characteristics, it was chosen by Lundin Petroleum for anchoring and de-anchoring its platform, the “Island Innovator”.

Extremely versatile, the vessel can carry out missions such as resupply, hydrocarbons recovery, stand-by, firefighting, rescue (room on board for up to 300 survivors) and interventions with remotely-operated underwater vehicles (ROV). With a reinforced hull and equipment designed to withstand extreme conditions (“Ice“ Class), the Bourbon Arctic is completely suited to work in temperatures as cold as -20° C, under the best possible safety conditions.

WE GO WHERE… THEY GO !Last February, BOURBON launched a campaign in "Word Oil" magazine and "Offshore Magazine," two major media players in the offshore world. The goals: making the subsea service stand out from the competition, and make it more visible and attractive to clients throughout the world.

The group decided to establish a campaign that emphasized its expertise in offshore subsea operations, and enable it to establish its ability to offer a wide range of services, anywhere in the world.“We go where you go” : this slogan, with its dual meanings, highlights BOURBON ability to be present anywhere that its clients operate, and also at great depths. Accompanied by a discussion of simple, factual evidence, it gives meaning to this campaign, distributed in the first half of 2015.

2015 HIGHLIGHTS

In just 8 months of operations in the Mediterranean for Doctors Without Borders (MSF), the Bourbon Argos in 2015 rescued over 12,000 migrants, for 75 interventions performed.

As impressive as it may be, the number of rescues performed by the Bourbon Argos only partially tells the story of the scale of the job performed by the members of Doctors Without Borders (MSF), assisted by the crew of the vessel. For many months, the crew had to handle not only the technical aspect of the operations, but above all the human aspect, with these vulnerable populations who needed to be rescued, welcomed, reassured, and comforted all at once.

“The crew and the MSF teams have to find the right words to explain to them that everything is OK, they are safe and sound, under protection. We calm them, give them water, food, clothing, and first aid if needed.” explains the Captain Ruslan Voznyuk. Over the course of these operations, unusual for a vessel dedicated to offshore, the crew did their duty, by ensuring the safety of navigation and persons with professionalism.

In this context, BOURBON has made a €30,000 to Doctors Without Borders, enabling the association to cover the costs related to the purchase of life-vests and survival blankets for protecting the refugees from the cold.

2015 HIGHLIGHTS

MEXICO, TOWARD THE OFFSHORE REVOLUTIONRich in oil & gas, Mexico derives much of its revenue from oil production, which now stands at 2.2 million barrels a day. It was less than 10 years ago, but the recent liberalization of the energy market in Mexico is opening up excellent prospects.

“"Faced with the natural decline of the main fields, and the need to meet the population's growing energy needs, the country took the initiative of opening its market to foreign companies." says Gerardo Sanchez Gonzalez, Managing Director of Naviera Bourbon Tamaulipas. The objective? Partnering with Majors or local and regional players, in order to develop deepwater offshore and gas extraction.

It's enough to create new opportunities for offshore oil & gas maritime service companies, such as Naviera Bourbon Tamaulipas. “ More projects, and also more logistical services and more vessels! We are equipped to meet the new needs of our historical customer Pemex, as well as those companies which soon will be entering the Mexican market" says Gerardo Sanchez Gonzalez.

Founded in Mexico in 2005, Naviera Bourbon Tamaulipas operates a comprehensive, modern fleet, the most recent in the country, with an average vessel age of only 5.8 years. “Our fleet contains 25 vessels, including one AHTS and two PSV Bourbon Liberty 150 vessels, as well as personnel transport , fire-fighting and pollution control vessels," adds Gerardo Sanchez Gonzalez. Most feature diesel-electric propulsion, a pledge of cost optimization for clients, who can also rely on the availability of rock-solid vessels. This way, the company enjoys BOURBON standards, not just technically but also in terms of safety.

In May 2015, BOURBON teams, aboard the Argonaute, a 69 meter-long AHTS equipped with a Falcon series ROV*, conducted the laying of a 2 km long submarine cable south of the island of Ushant, prior to connecting the first tidal turbine to the French national electrical grid. Four months later, during a second operation conducted again by the Argonaute, the Sabella D10 tidal turbine, submerged in the Fromveur Passage at a depth of 55 meters, was connected to its submarine electrical cable and could thus produce the first killowatts for the island.

It was the first installation of its kind in France, initiated by Sabella, an engineering and project management company specializing in marine energy, and it was a real success! Yet, from the first operation, the challenges were many: a narrow corridor, strong currents, and a cable weighing nearly 30 tons to be landed, placed, and buried in the seabed, at depths between 0 and 60 m. After 2 weeks of preparation by the BOURBON engineering teams, the mission was accomplished in 4 days. The connection between the tidal turbine and the cable was to occur sometime in September, with the same players, in this are of powerful currents.The major issue of this operation is to supply 15% of the island's energy needs for 1 year. If the trials are successful, it will be possible to mass produce new turbines, and then cover much of Ushant's electricity needs. By participating in this project, BOURBON clearly demonstrated its capabilities in the field of renewable energy, from engineering to the operation itself.*Remotely operated underwater vehicle.

HYDRATES CLEANING:AN ALTERNATIVE TO METHANOLOne of the challenges facing the oil & gas industry is cleaning hydrates that may have consolidated and accumulated on the outside of subsea structures. Cleaning with a high pressure stream of water is an interesting alternative to methanol: it's economical, fast, and less risky for individuals and the environment.

Hydrates are deposits similar to "ice" that form under particular pressure and temperature conditions on subsea structures in deep water, and which can affect equipment operation. Therefore it is necessary to clean them regularly.

For this type of water jet cleaning operation, BOURBON used the Bourbon Trieste, a vessel specializing in inspection, maintenance, and repair (IMR), which works with a UHD ROV. This operation, conducted on behalf of Exxon off the coast of Angola, consisted of using a water jet to clean a wellhead at a depth of 1400 m. The cleaning removed all the hydrates, while protesting the hydraulic lines and cables. Since then, BOURBON has successfully performed this procedure several times, thus illustrating the client's confidence in its expertise.

MYBOURBON: DATA MANAGEMENT SERVING CLIENTS

This Extranet, a client brick in the BOURBON digital transformation strategy, is a strong sign of the group's commitment to a culture that is steadfastly turned toward differentiating its service offering, to proximity with its clients, and to transparency regarding service quality.

To maintain its leadership, BOURBON has always looked to innovation, and myBOURBON has no equivalent in the offshore marine services industry. This client Extranet is in fact aimed at delivering the necessary to our most demanding clients, in order to enable them to improve the management of their contracts and the performance of their fleet. Nathalie Olszewski, Project Director, explains: “myBOURBON is a particularly powerful tool, which enables our clients to track the position and operational data of units in the BOURBON fleet they have contracted, via tabs such as HSE, crews, maintenance, fuel, fleet (daily log). We bring them data compared with other data from our different bases to provide them with consolidated information, that's the value added of myBOURBON.”

It's an approach that ensures continued improvement since, thanks to the data collected, cross-referenced, and correlated, BOURBON can guide its clients on the possible pathways for improving their contracts and, thus, provided them with personalized expertise.On the client side, it is essentially offshore Majors, national oil & gas companies operating internationally, as well as all clients seeking to optimize their operations and have a new view of managing their contracts, who will be offered this service.

Result: better client satisfactionAsked to test and improve the tool, some clients immediately weighed the benefits, like BP.For their operations in Trinidad and Tobago, myBOURBON was tested in prototype version. “Our client was convinced by the tool's

viability, particularly the Crewing (planned crew, changeover day, seafarer certificates, etc.), documents, HSE and fuel sections” says the Managing Director of Bourbon Offshore Trinidad. “Now, it's up to us to demonstrate that this tool provides all the useful data and that it is essential in managing the client contract.”

Now that the first version of myBOURBON is operational, the goal is to continue to develop this service, so that it provides a 360° view for the optimized management of their contracts and, in fact, of their projects throughout the world.

CURRENT MEMBERS OF THE BOARD OF DIRECTORS ARE:

Anticipating the crisis that has affected the offshore oil industry since Summer 2014, BOURBON had two action plans in place making it possible to track recurring vessel expenses on a monthly basis and rapidly reduce their costs when they are decommissioned. A two-fold strategy.

It first involved analyzing expenses as thoroughly as possible, in order to evaluate the usefulness and relevance, before determining the justifiable needs in all of the group's areas of activity, in order to redimension the available fleet, teams, and bring all expenses down to what is strictly necessary.

Objective: adopting the best practices at all levels of the company. Efforts have been made on every front: on personnel travel, supplies purchases, office rental, using external service providers, telephone service...many contracts with suppliers were also renegotiated downward. The same philosophy guided us in preparing several vessels in the fleet for decommissioning, a decision made necessary by the decrease in offshore exploration

and production activity. The vessels were grouped together as much as possible, in this case in the ports of Abidjan (Ivory Coast) and Batam (Indonesia), which made it possible to pool the maintenance teams among several affiliates, and thus optimize costs. For older vessels, sale is sometimes preferable to decommissioning.
