GHHL Installs first 200 meter flare with the Terex® CC 8800-1 crane

High capacity crawler crane delivers efficient transport, set-up and configuration changes


YANBU, Kingdom of Saudi Arabia June 8th, 2015 – A country rich with oil, the Kingdom of Saudi Arabia has unique equipment needs when it comes to the oil industry. Lifting and heavy hauling companies like Gulf Haulage Heavy Lift (GHHL), Dammam, Kingdom of Saudi Arabia (K.S.A.), must be ready to quickly respond to projects demanding the specialized equipment necessary to build and repair oil refineries, critical to K.S.A.’s economy.

Changing environmental regulation updates further complicate business practices by changing the design parameters of refining equipment, so lifting companies must have flexible equipment in their fleets in order to adapt to these evolving needs. For example, the Saudi Arabian Government’s environmental improvement program recently increased the height standards for flare stacks used to burn off flammable gas generated by the oil refining process.

Saudi Aramaco was the first oil company to install a flare stack at its Yanbu, K.S.A. facility under these new environmental guidelines. The structure installed was constructed to a height of 200 m (656 ft). With stack structure segments weighing from 21 to 104 tonnes (23 to 115 US tons), GHHL was hired to provide the heavy lifting. The combination of structure weight and height and difficult site conditions meant that only one crane in GHHL’s fleets was the right choice to efficiently complete the job on time and within budget, the Terex® CC 8800-1.

Challenging Project

The sheer size and weight of structure segments made the construction project difficult enough. However, the Yanbu refinery’s location, nearby the Red Sea, severely limited the time crews had to complete each lift.

“Every day at approximately 11:00 hours winds would increase from a light breeze of 2 m/s (4.5 mph) to sustained gusts reaching 16 m/s (35.8 mph), and this would sometimes continue all afternoon and evening,” explained Sanjay Pachisia, general manager of GHHL. This was well outside the project’s permissible lift wind speed levels, which ranged from 4.1 m/s (9.2 mph) to 7.1 m/s (15.9 mph), depending on which flare section was being positioned.

The project also required a low ground bearing pressure of 12 t/m2 (1.3 t/ft2) for constructing the crane’s boom configurations and lifting the flare stack. “The CC 8800-1 crawler crane has 2-m (6.6-ft) wide tracks and offers a wide 10.5-m (34.4-ft) stance to help disburse the weight over a wide area for heavy lift projects,” says Christian Kassner, Senior Sales Manager for Terex Cranes. A wide crawler stance plus the use of heavy-duty, 5-m-long x 2.8-m-wide x 0.36-m-thick (16.4 ft x 9.2 ft x 1.2 ft) thick steel matting helped GHHL’s operators meet the project’s ground pressure requirements for the crane.

Additionally, precise rigging and flare section placement was a must on this project. “The center of gravity for each section was not in the center of the flare structures due to the risers, nor was the section installed in the center of the structure,” says Pachisia.

Boom strategy saves time

With the site challenges and flare section size and weight known, GHHL prepared and mobilized the CC 8800-1 crane components for the nearly 1,400 km (870-mi) trip from its Dammam headquarters to the Yanbu project site. “To move the crane, we used 7 heavy duty trailers, 12 low-bed trailers and 40 flat-bed trailers with 12-m (39.4-ft) deck lengths,” says Pachisia.

Designed and built as a series, the 1,600-t (1,764-US t) capacity Terex CC 8800-1 crane has a standardized production process, so that transportation, rigging and maintenance ease are built into each crane. “Every component is less than 3.5-m (11.5-ft) wide, and most components have a shipping weight of less than 40 t (44 US t),” adds Kassner. “By making the crane as a production model, Terex offers significant advantages over competitive, one-off custom-design cranes that are made to meet a specific market’s need.”

Once on site, GHHL’s five-person rigging crew began crane assembly. For the first lift, which placed the third-level flare segment 100.3-m (329.1-ft) above ground level, the CC 8800-1 was equipped with 108 m (354.3 ft) of main boom and its superlift system to hoist the 104 t (114.6 US t) section into place.

For the second and third lifts, which placed the level four segment and level five structure into position, crews simply reconfigured the crane by adding its luffing jib on the main boom. “We chose the crane configurations carefully, in a way that the change consisted of only adding luffing jib boom sections and not change the main boom length,” says Pachisia. “This way, we reduced crane reconfiguration time substantially.” Hydraulic pin connections between boom segments greatly simplified adding boom segments.

The final three lifts for flare structure levels six through eight required one final configuration change. In addition to the main boom, crews used the luffing jib – configured to the maximum boom length of 216 m (708 ft) – and available Runner Winch, so they would have the necessary height and control to place these segments.

In all, the Yanbu Aramco Sinopec Refinery Project required just 11 working days to complete the six complex lifts to finish placing the flare stack segments. Once completed, crews disassembled the CC 8800-1 crane and mobilized it back to GHHL’s Dammam facility, a process that took approximately 10 days.

“We have received first-class service from Terex and the CC 8800-1 crane on this and other projects,” says Pachisia. “We appreciate every effort taken by the Terex after sales department to provide us with technical assistance, day or night, so we can be successful with difficult projects like the flare stack project in Yanbu.”
