Our primary business is marine transportation services in support of the upstream oil and gas industry. Since entering the market in 1990, we have steadily evolved into a global, growth-oriented marine services provider known for our technologically advanced fleet and quality performance. We have earned a reputation for consistent performance, safe operations and a dedication to exceptional service. With a commitment to meeting the needs of our clients in the ever-changing offshore environment, we have grown rapidly through the continuous expansion and modernization of our fleet. Newly constructed vessels added since 2005, represent more than 60%. We continue to add a diverse mix of highly capable vessels whilst selling older, non-strategic assets, and remain one of the youngest global fleets in the industry. Starting with a strong position in the North Sea, where we are the largest operator of Platform Supply Vessels, we have built a balanced global footprint in major energy-producing regions. We now operate significant fleets in the high-growth markets of Southeast Asia and in the Americas, including the high-potential deepwater basins offshore Brazil and the Gulf of Mexico. Our fleet includes 72 offshore vessels in various markets throughout the world.
