Refurbishment of Technip’s Flagship Vessel — The Deep Blue

Technip is a global leader in oil and gas projects, technologies, systems and services. Technip partnered with Core to prep its flagship vessel, The Deep Blue, for refurbishment in July 2016. The Deep Blue is one of the most advanced pipelay and construction vessels in the subsea industry. As part of refurbishment, the Deep Blue required specialized care and support to deconstruct certain equipment and perform maintenance and repairs.

This vessel has an aligner wheel, for coiling and uncoiling pipe and umbilicals, installed approximately 300 feet above its top deck. Core’s experienced staff were contracted to plan and execute the removal of this aligner wheel and its attachments for refurbishment. To accomplish this, we reconfigured our Heavy-Lift Manitowoc Crane. What made this lift especially unique was the need to lift the wheel vertically but place it horizontally onshore. Because of the complexity of this project, it took nearly two days, two cranes and about 15 people to complete.

Once deconstructed and offloaded to our facility, our team then assisted in metal refurbishment, welding on the aligner wheel as well as maintenance/repair to the bearings and other wheel internals, and blasting and repainting of the entire wheel. In conjunction with this work, we also removed lattice frames and several other pieces of equipment for refurbishment. While this work was being conducted, the ship was sent for full refurbishment at a shipyard. Once all work was complete, Core reinstalled and reconfigured the aligner wheel and other equipment onto the Deep Blue.

Mobilization of Heerema’s New DCV Aegir

In March 2014, Core served as a shore base for Hereema Marine Contractors and their newest vessel — the deepwater construction vessel (DCV) Aegir. This was the Aegir’s first port call in the U.S. on its maiden voyage from the Netherlands. It was designed for use on complex oil and gas infrastructure and pipeline projects in ultra-deep water. Core’s team supported demobilization and storage of heavy reels and other project equipment.

The Aegir was at port for two weeks while Core provided assistance for remote operated vessels as well as welding. This particular vessel can be configured to support various types of projects, such as laying umbilicals and collecting umbilicals. Our team provided support for demobilizing equipment that was not necessary for the Aegir’s next assignment using our heavy-lift capabilities and supported configuration of the vessel once that equipment was offloaded and stored.

Core is equipped with the facilities and space to store equipment, long-term or short-term, while providing preservation and maintenance. The Aegir redocked in fall 2014 after deployment to the Gulf of Mexico. Core assisted Heerema in reloading the stored equipment back onto the vessel.  

The Aegir will be returning to Core’s private port facility in 2017.
