Company Overview [Abstract]
Company Overview	Note 2 — Company Overview Our Operations We are an international offshore energy company that provides specialty services to the offshore energy industry, with a focus on well intervention and robotics operations. We seek to provide services and methodologies that we believe are critical to developing offshore reservoirs and maximizing production economics. We provide services primarily in deepwater in the Gulf of Mexico, North Sea, Asia Pacific and West Africa regions. Our “life of field” services are segregated into four business segments: Well Intervention, Robotics, Subsea Construction and Production Facilities (Note 11). Our Subsea Construction segment was significantly diminished following the sale of substantially all of our assets related to this reportable segment during 2013 and early 2014 (see Note 2 to our 2013 Form 10-K and Note 2 to our Quarterly Report on Form 10-Q for the three-month period ended March 31, 2014). Our Production Facilities segment includes the Helix Producer I (“HP I”) vessel (which we now own 100% after acquiring our minority partner’s noncontrolling interests in the entity that owns the vessel for $20.1 million in February 2014) as well as our equity investments in Deepwater Gateway, L.L.C. (“Deepwater Gateway”) and Independence Hub, LLC (“Independence Hub”) (Note 5). The Production Facilities segment also includes the Helix Fast Response System (“HFRS”), which provides certain operators access to our Q4000 and HP I vessels. Discontinued Operations In February 2013, we sold Energy Resource Technology GOM, Inc. (“ERT”), a former wholly-owned U.S. subsidiary that conducted our oil and gas operations in the Gulf of Mexico, for $624 million plus additional consideration in the form of overriding royalty interests in ERT’s Wang well and certain exploration prospects. As a result, we have presented the historical operating results of our former Oil and Gas segment as discontinued operations in the accompanying condensed consolidated financial statements.

Our Operations

We are an international offshore energy company that provides specialty services to the offshore energy industry, with a focus on well intervention and robotics operations. We seek to provide services and methodologies that we believe are critical to developing offshore reservoirs and maximizing production economics. We provide services primarily in deepwater in the Gulf of Mexico, North Sea, Asia Pacific and West Africa regions. Our “life of field” services are segregated into four business segments: Well Intervention, Robotics, Subsea Construction and Production Facilities (Note 11). Our Subsea Construction segment was significantly diminished following the sale of substantially all of our assets related to this reportable segment during 2013 and early 2014 (see Note 2 to our 2013 Form 10-K and Note 2 to our Quarterly Report on Form 10-Q for the three-month period ended March 31, 2014). Our Production Facilities segment includes the Helix Producer I (“HP I”) vessel (which we now own 100% after acquiring our minority partner’s noncontrolling interests in the entity that owns the vessel for $20.1 million in February 2014) as well as our equity investments in Deepwater Gateway, L.L.C.
