Description

The Sub Assembly Shop is the first stop in the shipbuilding process. Steel is delivered to this facility, which houses the most world-class, state-of-the-art equipment available for cutting steel plates and profiles.

In addition to a 13 meter ESAB plasma cutting/tracing/beveling/marking machine, which covers two work stations to provide for a continuous flow of work (steel can be loaded and cut on one while another is prepped), the 4000m² (43,000 sq. ft.) shop also includes a processing line equipped with a CNC robotic profile cutting machine, and five (5) stations dedicated to the assembly of small parts and sub-assemblies.

Description

Efficiency is the operative word for this step in the shipbuilding process. The purpose of the Panel Shop is to produce flat panels. To start the procedure, a three-headed submerged arc Welding Machine, from Lincoln Electric, joins steel plates up to 12m (39 ft.) in length. The unit welds two plates together from one side in a single pass, making the process approximately 14 times quicker than traditional methods, which also requires more manpower for tasks like turning the gigantic panels.

In addition, the Panel Line accurately cuts the perimeter of the panel and all internal holes required for installation of piping, cabling, etc. Following the steel down the conveyer line, stiffeners are automatically fit to the panel (again, with greater efficiency and accuracy) as six (6) automated welding heads working at once provide amazing efficiencies for the joining of stiffeners to the panel.

By the time the panel reaches the end of the line, it's ready to be moved using self propelled modular transporters (SPMTs) to the Block Assembly Shop.

Description

The Forming Shop forms/bends steel plates and profiles to the ship's final hull shape. This shop also boasts one of the most technologically advanced pieces of machinery in shipbuilding today – a 1000T Hydraulic Plate Press. The cold forming press can shape steel up to two and a half inches thick. Once the steel is formed, it moves to a section within the Block Assembly Shop that consists of steel pin jigs to allow pieces to be welded together.

Description

This is a new state of the art facility for fitting and welding of vessel hull blocks up to 24m x 24m (78 ft. x 78 ft.) in size. The Block Assembly Shop is also where curved and three-dimensional blocks are manufactured along with installation of hot outfitting items, like hangers for cables and pipes. With the joining of welded sub-assemblies and panels together, the vessel begins to take a recognizable shape in this shop. Steel panels from the panel line and sub-assemblies are brought together in 20 to 40 tonne pieces, and are assembled into hull blocks in this shop before taking one of two routes, either directly to the Pre-Outfitting Shop or more typically to the Blast & Paint Shop.

Images

Description

Canada's largest permanent gantry crane, with a lifting capacity of up to 300 tonnes, is used for the pre-erection and erection of blocks and grand blocks (pieces of the ship welded together to form the final product). The crane travels 250 metres (820 ft.) north and south and spans 76 metres.

Pre-Erection/Final Assemby Area

Images

Description

The pre-erection area, located on the east side of the yard and under the 300T Gantry Crane (Big Blue), is used to join hull blocks together to form grand blocks. After the blocks are joined, outfitting systems are installed across block breaks.

Rolling shelters are transferred over the blocks/grand blocks to provide sheltered workplaces.

Once grand blocks are complete and assembled as one large section, the shelters are moved to prepare the grand blocks for erection.

Erection Berth

Images

Description

The Erection Berth provides a flat level concrete surface where vessels up to 200 metres in length are erected. As grand blocks are completed in the Pre-Erection Area, the 300T Gantry Crane (Big Blue) lifts the grand blocks (if not exceeding 300T) onto the Erection Berth. Grand blocks forming the bottom of the vessel can reach up to 800T and are moved by Self-Propelled Mobile Transporters (SPMTs) to the erection berth.

The Erection Berth receives all grand blocks for the final assembly of the vessel. Work at this stage also includes completion of all outfitting, testing of systems, and final paint. The vessel is 95% complete before leaving the berth for its first trip to the water.

Loadout Pier

Images

Description

The transfer of the vessel from land to sea consists of a roll-on floating platform, which is then transferred into deeper water and sunk, leaving the new vessel to float.

The floating platform is called the Seaspan Careen, an autonomous drydock with its own generators to provide power. The Loadout Pier was constructed at the end of the Erection Berth in order to tie the drydock into the yard and with sufficient water depth. The end of the Loadout Pier measures 32m (104 ft.) in width, the same as the Seaspan Careen.
