Modular, Portable Spoolbase McDermott has custom designed, engineered and built a portable spoolbase to produce pipe stalks for Reel-Lay operations to support our deepwater Reel-Lay subsea construction vessels, the Lay Vessel North Ocean 105 (LV105) and Lay Vessel 108. The portable and modular nature of this facility allows it to be rapidly deployed to sites requiring minimum ground preparation or infrastructure development. The length and width of the pipe storage racks are adaptable to site conditions, which allow the spoolbase to be located close to a project site. This configuration provides an economical solution for the execution of rigid- reeled pipeline projects. Advanced Welding Technology Developed in accordance to DNV OS-F101 and RP F108, our advanced automatic welding technology, equipment and decades of pipeline welding experience combine to produce stalks with the highest quality welds. The McDermott bug and band (JBBS) and framed (JAWS) automatic welding systems consistently deliver excellent production rates with exceptional mechanical properties and minimal weld repairs. These welding systems utilize state of the art welding power supplies to produce Pulsed Gas Metal Arc Welding as well as Surface Tension Transfer welds on carbon steel as well as Corrosion Resistant Alloy materials.

The McDermott modular, portable spoolbase adds value and strengthens our ability to meet the growing demand for deepwater and ultra-deepwater rigid pipeline installations.Engineering Management: A team of experts manages line pipe specifications through to the development of Engineering Critical Assessment to ensure compliance with DNV-RP-F108.Capabilities: The spoolbase facility encompasses line pipe storage and handling, stalking and reeling support of pipelines from 6 to 16 inches. Adaptable station assignments are optimized for project specific welding, NDT and field joint coating requirements.Welding and NDT: Automated welding processes are used in combination with the latest AUT NDT technologies to ensure superior welds made in low cycle times.Portability: Spoolbase equipment is designed to be transported in shipping containers and flat racks. It is road transportable to remote locations and can be erected with minimal / locally available resources.

The spoolbase facility consists of two major parts:• Stalk Welding Facility – Modular welding stations can be assembled to support a 394-foot length pipe tunnel, complete with a tension machine. Station assignments can be made to optimize the number of welding and NDT stations required, as well as the placement of field joint stations. • Stalk Storage Racks – Modular racks with a dual pipe roller track can be set up to virtually unlimited lengths or widths based on the available site conditions. Pipe handling is executed by four 85-tonne Caterpillar excavators with pipe handling roller boxes.

PROJECT EXPERIENCETo support a rigid reel pipeline project offshore Malaysia, McDermott erected the portable spoolbase in our busy fabrication facility on Batam Island, Indonesia. Pipe stalks were made in 2297-foot lengths to suit the site conditions. A total of 28 miles of pipe stalks, comprising 10-inch single pipe stalks and 8/12-inch Pipe-in-Pipe stalks, were produced and stored in preparation for reeling onto LV105. Welding was performed with the JBBS system. More than 6,000 welds were produced with a repair rate of less than 1%. Construction work at the fabrication facility continued uninterrupted around the busy spoolbase
