We are an international offshore energy services company that provides specialty services to the offshore energy industry, with a focus on well intervention, robotics and full-field decommissioning operations. Our services are key in supporting a global energy transition by maximizing production of existing oil and gas reserves, decommissioning end-of-life oil and gas fields and supporting renewable energy developments. We provide a range of services to the oil and gas and renewable energy markets primarily in the Gulf of Mexico, U.S. East Coast, Brazil, North Sea, Asia Pacific and West Africa regions. We expanded our service capabilities to the Gulf of Mexico shelf with the acquisition of the Alliance group of companies (collectively “Alliance”) on July 1, 2022, which we re-branded as Helix Alliance. Our North Sea operations and our Gulf of Mexico shelf operations related to Helix Alliance are usually subject to seasonal changes in demand, which generally peaks in the summer months and declines in the winter months.</p><p style="font-family:'Arial','Helvetica','sans-serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Our Operations</p><p style="font-family:'Arial','Helvetica','sans-serif';font-size:10pt;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Our services are segregated into four reportable business segments: Well Intervention, Robotics, Shallow Water Abandonment, which was formed in the third quarter 2022 comprising the Helix Alliance business, and Production Facilities.</p><p style="font-family:'Arial','Helvetica','sans-serif';font-size:10pt;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Our Well Intervention segment provides services enabling our customers to safely access subsea offshore wells for the purpose of performing production enhancement or decommissioning operations, thereby mitigating the need to drill new wells by extending the useful lives of existing wells and preserving the environment by preventing uncontrolled releases of oil and natural gas. Our well intervention vessels include the <i style="font-style:italic;">Q4000</i>, the <i style="font-style:italic;">Q5000</i>, the <i style="font-style:italic;">Q7000</i>, the <i style="font-style:italic;">Seawell</i>, the<i style="font-style:italic;"> Well Enhancer</i>, and two chartered monohull vessels, the <i style="font-style:italic;">Siem Helix</i> <i style="font-style:italic;">1</i> and the <i style="font-style:italic;">Siem Helix</i> <i style="font-style:italic;">2</i>. Our well intervention equipment includes intervention systems such as intervention riser systems (“IRSs”), subsea intervention lubricators (“SILs”) and the Riserless Open-water Abandonment Module, some of which we provide on a stand-alone basis.</p><p style="font-family:'Arial','Helvetica','sans-serif';font-size:10pt;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Our Robotics segment provides trenching, seabed clearance, offshore construction and inspection, repair and maintenance (“IRM”) services to both the oil and gas and the renewable energy markets globally, thereby assisting with the delivery of renewable energy and supporting the responsible transition away from a carbon-based economy. Additionally, our robotics services are used in and complement our well intervention services. Our Robotics segment includes remotely operated vehicles (“ROVs”), trenchers, the IROV boulder grab and robotics support vessels under term charters as well as spot vessels as needed. We offer our ROVs, trenchers and the IROV boulder grab on a stand-alone basis or on an integrated basis with chartered robotics support vessels.</p><p style="font-family:'Arial','Helvetica','sans-serif';font-size:10pt;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Our Shallow Water Abandonment segment provides services in support of the upstream and midstream ‎industries predominantly in the Gulf of Mexico shelf, including offshore oilfield decommissioning and ‎reclamation, project management, engineered solutions, intervention, maintenance, repair, heavy lift and commercial diving services. Our Shallow Water Abandonment segment includes a diversified fleet of marine assets including liftboats, offshore supply vessels (“OSVs”), dive support vessels (“DSVs”), a heavy lift derrick barge, a crew boat, plug and abandonment (“P&A”) systems and coiled tubing (“CT”) systems.</p><p style="font-family:'Arial','Helvetica','sans-serif';font-size:10pt;text-indent:36pt;margin:0pt;">Our Production Facilities segment includes the <i style="font-style:italic;">Helix Producer</i> <i style="font-style:italic;">I</i> (the “<i style="font-style:italic;">HP I</i>”), the Helix Fast Response System (the “HFRS”), and our ownership of mature oil and gas properties. All of our current Production Facilities activities are located in the Gulf of Mexico.</p>
