Our History
Subsea7 has been operating in the most challenging and unexplored environment on the planet – the vast, deep waters of our seas and oceans. The company carries out projects in every part of the globe to meet the ever-changing energy needs of our clients and society.
Subsea 7 was created on May 23, 2002 as a joint venture between DSND and Halliburton Subsea. In 2004, DSND acquired Halliburton’s stake in the joint venture and floated the business as Subsea 7 Inc on the Oslo Børs in Norway. In January 2011, Subsea 7 Inc combined with Acergy S.A. to form Subsea 7 S.A., that remains listed on the Oslo Børs with SUBC as its ticker.
Legacy companies
Subsea7 has a twenty-year history but it can trace its roots to over 25 different legacy companies and businesses which, since the 1950’s have evolved and overcome a succession of daunting subsea and marine challenges and, in the procdss, created the world-leading offshore contractor we are today.
Our timeline shows the historical relationships between the companies which ultimately came together as Subsea 7.
Although our industry has evolved drastically over the last fifty years as it adapted to the technological and logistical challenges of sourcing energy offshore, our story is fundamentally about a community of people with exceptional skills, knowledge and dedication working collaboratively towards a common goal. This is reflected in the title of the book and we encourage you to read our abridged version.
