Seaspan | Load-Out Pier Project

May 21, 2015

Project Status

Permit issued

On July 4, 2013, Seaspan submitted an application to amend approved project permit (PP 2012-088) due to changes in construction methods and footprint of the project. Seaspan facilities are under lease with the Port of Vancouver, and are located on the north shore of the Burrard Inlet in Vancouver. The project permit, including conditions is available below.

About the Project

As part of the Seaspan Shipyard Modernization Program, Seaspan constructed a 53.56 m long x 31.8 m wide concrete load-out pier covering 1,643 m2 (17,685 sq. ft. ) through the infilling of a caisson and sheet pile wall structure. Due to proposed changes to the construction and footprint of the load-out pier, Seaspan submitted an application to amend approved project permit (PP 2012-088).

Specific construction activities included:

  • Construction of an approximately 32 m wide x 50 m long concrete load-out pier with a proposed footprint of approximately 1,720 m² (18,514 sq. ft.);
  • Installing temporary four-sided sheetpile wall that extends approximately 3 m (10 ft.) beyond the perimeter of the final pier caisson footprint. The sheetpile wall enclosure will contain water and sediment during dredging activities;
  • Installing timber piles within the sheetpile wall enclosure to densify the seabed directly beneath the caisson placement area, as well as extending 3 m (10 ft.) beyond the berth face to densify the temporary sheetpile enclosure;
  • Once the timber piles have been driven to the desired depth, the piles will be cut at the seabed elevation using divers as required;
  • A 1 m (3 ft.) thick mattress rock layer will be placed over the timber densification piles inside the sheetpile enclosure, with pre-cast concrete caissons sunk over the rock mattress followed by fill material; and
  • Upon completion of the fill material placement and removal of the temporary sheet pile walls, rip-rap material will be placed along the side-slope area to retain the inner fill material and protect against wave-action.
