Halifax Yard Completes First Ship Lengthening Contract

The Canadian ship repairer Halifax Industries Limited, Nova Scotia, recently completed its first lengthening contract.

The contract was to lengthen the 4,700- grt products tanker M/V James Transport, owned by Halco Inc. of Montreal, by inserting a new 40-foot-long midbody section at a cost of approximately one million (Canadian) dollars.

The job was carried out at Halifax Ship yards in the company's floating dock, Scotiadock, and on completion provided the vessel with four additional cargo tanks.

After gas freeing and internal removals and disconnections, the James Transport was cut in two. The floating dock was then submerged enough to allow the bow section to be floated apart from the stern section. The floating dock was then raised to its normal position with the two sections 55 feet apart.

The new prefabricated 200-ton midbody section was then lifted into the dock in two sections — upper and lower — by means of Halifax Industries' floating timberland crane.

The new section was aligned and joined to the stern section of the vessel before Scotiadock was again flooded to allow the bow section to be floated back to the rest of the vessel.

After alignment, the two sections were welded and internal modifications completed.

The job took approximately 10 weeks to complete.

The new length of the M /"V James Transport is 411 feet, her breadth is 55 feet, and depth 27.5 feet.

Prefabrication of the new midbody section coincided with the completion at Halifax Shipyards of the yard's six-million- Canadian-dollar steel fabrication improvement program, which included a new panel welding line, a new numerically controlled burning machine, and an advanced surface treatment line.
