Moretrench congratulates Corporate Safety Director Greg  Lewis on being appointed to the National Commission for the Certification of Crane Operators’ (NCCCO) Foundation Drill Rig Operator Task Force.  The newly created task force is a logical extension of the well-established certification process for crane and pile driver operators, riggers and signal-persons.  Its purpose is to create a nationally recognized certification program specifically for drill rig operators that will be an effective tool in assisting companies to manage the risks involved in the use of foundation drill rigs.

“As of now, there is no certification for foundation drilling,” noted Lewis.  “This is a process I’ve been intimately involved with for the past five years that will further advance the safety of our industry and I am looking forward to seeing it through to completion .“

New Freeze Plant soon to join Moretrench’s Ground Freezing Fleet

Introduced in the early 1970s, mobile freeze plants radically widened the scope of jobs that could be accomplished by ground freezing and allowed this technology to be used in tight, urban environments for the first time.  Moretrench has been in the forefront of North America’s ground freezing field for more than 30 years.  As the call for this technique on complex underground projects continues to increase, we expand our capability accordingly to meet demand across a growing demographic area.

Our ground freezing division is getting ready to take delivery of a new plant, the third to be built for us by Toronto-based Cimco (Canadian Ice Machine Company).  The fully enclosed plants are built on 53-ft long galvanized trailers to resist brine corrosion and house the compressor, heat exchanger, condenser and all other components required to do the job.  Ammonia is the refrigerant used in the closed loop plant that chills the brine that circulates through the installed freeze pipes to freeze the ground.

We’ve mobilized our plants for work from Washington D.C to Seattle, north to Canada, and as far south as Buenos Aries, Argentina.   To learn more about our ground freezing projects, see our Services section.
