Helix Energy Solutions was formerly known as Cal Dive International. They provide specialty services for offshore energy operations in the Gulf of Mexico as well as in other regions including the Asia-Pacific and West Africa. They operate three divisions that include well support, robotics and production maintenance. The company is contracted by companies that own and operate large oil rig platforms and other offshore facilities.
Helix Well Operations
This segment handles subsea operations including decommissioning. They utilize specialized equipment such as an intervention riser system (IRS), intervention lubricator (SIL) and mobile equipment. Additional assets are the Q4000, MSV Seawell, and MSV Well Enhancer.
This division provides undersea intervention services utilizing remote operating vessels (ROV) and trenching. The company has 45 heavy work systems in place and five trenching systems as well as four support vessels. They provide offshore operations in three regions – Houston, Aberdeen, and Singapore.
This unit takes part in operations through contracted services with offshore oil and gas companies. They have several assets used in this segment, the Helix Producer I, Marco Polo and Independence Hub. The Helix Producer I is a single hull production and offloading vessel that was reconfigured to provide services for offshore assistance. The ship is 530 feet in length and 95 feet in width and has a depth of 47 feet. It assisted at the Deepwater Horizon site, a location that was to be decommissioned after a large fire and spill.
The Marco Polo field is located in Green Canyon area and is owned and operated by Anadarko Petroleum. It includes six wells and has a capacity of up to 50,000 barrels of crude oil and 150 million square feet of natural gas daily. It is a tension leg platform (TLP) that was fabricated in Korea. There are three deck levels, and it can sleep up to 26 people in its living quarters. An oil pipeline connects to the platform and extends about 75 miles where it connects with the Typhoon gas pipeline.
Independence Hub is in Mississippi Canyon at a depth of about 8,000 feet. It was developed by a group of various companies working together to find new locations throughout the eastern part of the gulf. The group consisted of affiliates of Enterprise and Atwater Valley Producers Group. The hub encompasses wells including Atlas, Jubilee, Merganser, San Jacinto, Spiderman, Vortex, Mondo NW, and Q.
In 2014 the company’s vessel Q4000 collided with a supply vessel. According to reports, the Q4000, semi-submersible well intervention rig, hit the side of the Odyssea Courage, causing damage to both vessels. The supply vessel went to Port Fourchon for repairs while the Helix vessel remained in the Gulf of Mexico with permission from the U.S. Coast Guard. There were no reported injuries in the incident.
