Woodfibre LNG Terminal Package "A"

Kiewit’s work on Woodfibre’s “Package A” project involved constructing new marine infrastructure, a “floatel” (floating hotel for on-site personnel) berth and a material offloading facility. The onshore civil works included demolition, shoreline dredging and rip rap placement. Additional scope included:

• The Material Offloading Facility (MOF) structure was founded on 169, 36-inch diameter piles, installed using a combination of DTH (down the hole hammer) drill system and vibratory / impact pile driving
• The floatel structure was supported by 16, 48-inch diameter piles. Piles ranging from 48 to 52 meters, were installed via a four-pile dolphin, starting with a 36-inch pile template. Kiewit used a bubble curtain to meet noise and environmental requirements.

To support this work, Kiewit used its marine yard on the Fraser River in Coquitlam, BC. This location was ideal for staging material deliveries, welding fabrication and barge loading.

In order to construct the project, the job team relied on Kiewit’s in-house temporary construction engineering group to design temporary structures including:

• Pile driving templates – to support install of Floatel and MOF dolphin piles
• Welding access platforms – to provide access to weld jacket shear lugs and access to weld pile caps to girders
