Westshore Terminals Berth 1 Emergency Repairs In early December of 2012 a bulk freighter impacted the approach trestle to Westshore’s Berth 1 shiploader. The accident collapsed a section of the structure and conveyor system, preventing access and coal transfer to Berth 1. Westshore faced significant loss of revenue for every day that the berth would be out of commission. In response to Westshore’s request for assistance, WorleyParsons mobilized to assess the damage and identify repairs. A project team consisting of Westshore, Worley Parsons, and Fraser River Pile and Dredge worked non-stop through the

holidays to meet an extremely tight, accelerated schedule designed to get Berth 1 operational as quickly as possible. The design of the replacement structure and materials handling system focused on using readily available resources and materials. This strategy and the efforts of the project team resulted in Berth 1 resuming operations ahead of schedule and under the insurance evaluation budgets.

New Transloading Terminal A Canadian refinery recently installed new truck loading and railcar unloading terminals to improve product transfer capabilities. The upgrade provides diesel blending, allows terminal services for oil products, and includes capabilities for receiving future biodiesel shipments. The new, modular two-lane truck loading rack includes eight gasoline/distillate loading arms; continuous blending of gasoline, ethanol, and distillates; capacity to load four trucks per hour; a glycol-heated truck apron to prevent ice buildup; and fire detection and emergency shutdown equipment. The new rail car unloading rack includes product unloading stations for 10 rail cars, adjustable gangways to accommodate varying car lengths, and fire detection and emergency shutdown pushbuttons. As part of their design engineering services, Anvil Corporation’s multi- discipline services included developing an ergonomic design to ensure safe loading/unloading operations and a non-conventional, submersible, top-unloading pump system to ensure environmental compliance. The facility is completed and operational. Donald Bridge and Approaches The Donald Bridge and Approaches Project on the Trans-Canada Highway (TCH) west of Golden, BC, comprises widening and realignment of 4.4 km of highway and replacing two bridges, including the Donald Bridge over the Columbia River. Associated Engineering and subconsultants Urban Systems, Golder Associates, Northwest Hydraulic Consultants and PBA Engineering developed a constructable, environmentally sound solution that will be maintainable and cost effective over its design life. Associated Engineering designed the 302 m Donald Bridge, a five-span, steel plate girder structure comprising three continuous spans and two simply supported jump spans at the abutments. The alignment crosses the Columbia River with an 825 m horizontal curve and a 1% longitudinal gradient. The concrete piers supported on steel pipe piles were designed to address geotechnical concerns related to steeply sloping bedrock.
