Point Lepreau

LMC/QUALMEC worked with Atomic Energy of Canada Limited (AECL) on the massive refurbishment project at the Point Lepreau Nuclear Power Station in southern New Brunswick.

This project was led by Carl Tremblay, and Fred Bouchard, Project Manager. "LMC was proud to provide labour and equipment for re-tubing, supervision and other related services for the mechanical portion of the reactor refurbishment," says Carl Tremblay. "We are one of the first companies in Canada to do this kind of highly technical work. Developing these specialized erection and welding techniques has prepared us for other similar projects in the Northeast and around the world."

The Point Lepreau Generating Station is the first of the world's fleet of CANDU 6 reactors to undergo a refurbishment. The main activities include the replacement of all 380 fuel channels, calandria tubes and feeder pipes as well as other station maintenance work. Atomic Energy of Canada Limited (AECL) is the main contractor and the original designer of the station. The Point Lepreau Generating Station provides up to 30 per cent of New Brunswick's electricity and is one of the lowest cost generators on NB Power's electrical system.

Liquefied Natural Gas Terminal

In October, 2006, under the leadership of Styve Dumouchel, CEO, LMC/QUALMEC was awarded a contract for the mechanical erection of three 160,000 cubic-meter storage tanks in Canada's first liquefied natural gas (LNG) terminal constructed in Saint John, New Brunswick.

“LNG tanks are more complex than typical storage tanks and use advanced welding procedures. The inner tank is made of nine per cent nickel alloy steel,” says Mr. Dumouchel. At peak, more than 250 workers were employed on the project by LMC.

"The expertise required to construct these tanks is significant and the fact that we have many local companies working on the site is a testament to the expertise readily available right here in the region," says Jorge Ciacciarelli, General Manager of Canaport LNG.

Canaport LNG is a partnership between Irving Oil Limited and Spanish energy giant, Repsol. Canada's first LNG receiving and regasification terminal now supplies up to 1.2 billion cubic feet of clean-burning natural gas per day to northeastern markets via Emera's Brunswick Pipeline and its connection with the Maritimes & Northeast Pipeline.

Nickel Processing Plant

Canadian mining company Vale INCO. constructed a major processing facility at Long Harbour, Newfoundland to produce finished nickel product mined from the Voisey’s Bay deposits. This construction budget was close to US$ 3 billion and during operations the plant will employ nearly 500 people. Construction of the Long Harbour Processing Plant is expected to generate approximately 5,750 person-years of employment.

LMC/QUALMEC was awarded the contract to construct one of the buildings on site to help house the processing plant. This is LMC/QUALMEC’s first job in Newfoundland. With this foray into the province, we are well poised for additional industrial projects being developed in Newfoundland and Labrador.

Design, Fabricate and Install Waste Spent Acid Condenser , IOL Saint John, NB

Completion Date: Fall 2011

Scope of this project included the Fabrication and Installation of the Haldor Topsoe WSA Condenser as well as all of its associated Ductwork. Timelines of the project were very aggressive from the beginning due to the rapidly deteriorating condition of the existing unit and the urgent need for its replacement. A review of the design of the unit was required to ensure all applicable North American codes were complied with. Also, gas ducting was redesigned to be ASME compliant due to lethal nature of the transported gases. The installation scope involved the demolition and removal of existing ducting and WSA Unit as well as its subsequent replacement with a new WSA unit and associated ducting. This work was performed in parallel with normal maintenance work on the other equipment in the acid recovery plant such as the electrostatic precipitator, the combustor, the SO2 reactor, the salt drum and other equipment. Despite numerous challenges associated with technical nature of the project and aggressive timelines required the project was successful on all fronts: Safety, Quality, Schedule and Budget.
