Pipeline Stringing

Montgomery Trucking Co. has a fleet of steerable pole trailers that enable the long loads to be transported into storage yards and pipeline right of ways around the country.  The specialized hauling is performed by a group of very experienced drivers who have many years of experience with the hazardous loads.  Almost all the drivers that work full time for the company have more than 10 years experience and the larger percentage have tenure exceeding 20 years. 

The steerable pole trailers are equipped with large metal chocks/blocks that are adjusted so the pipe is held precisely in place while being transported over uneven terrain.  The trailers are engineered so the rear tandem axel steers near the same tracks as the tractor by using cables that alternate from one side of the tractor to the opposite sides of the trailer.   The bolster on the trailer has a turn table that allows the trailer to steer.   

We along with our customers demand that all safety procedures are followed at all times.  Montgomery Trucking Co. has been responsible for many of the safety innovations regarding transportation and handling of line pipe that have been created over the years.  This includes the precise blocking and securing of loads; as an example when taking discharge from ocean going vessels the company builds precise dunnage for the safe transportation of the pipe.  The company utilizes cranes and aluminum end hooks on most small diameter pipeline projects and excavators and vacuum lifts are used on most large diameter projects for the pipe handling. 

The over length loads of pipe are often delivered into very adverse terrains and conditions requiring more than typical load securing techniques.  All of the trucks utilized in our transportation operations are equipped with towing packages that allow the truck and trailer to be towed in adverse conditions.  When conditions get too bad for the stringing truck to go down the right of way the pipe is trans-loaded to equipment that has high floatation tires that can traverse the mud or deep sand on the right of way. 

Montgomery Trucking Co. utilizes safety supervisors on projects.  The safety supervisors have many functions, but primarily they make sure that all transportation functions are performed in the safest manner possible.  This includes that proper loading, load securement and unloading operations are adhered to.  The equipment utilized on pipeline projects is subject to excessive wear and tear because of the harsh conditions that are encountered on the pipeline right of ways.  This requires hour by hour inspection of all equipment which is performed by the truck drivers and safety supervisors. The proper routes to and from the right of way requires working with company and contractor personnel to assure that no vehicle travels onto unauthorized roads.  Additionally project safety supervisors coordinate with the company on the amount of pipe to be strung on the right of way each day.  The stringing progress must be constantly assessed as to not pass the front end crews of the pipeline contractor and insure staying ahead of the bending and welding crews.  The number of trucks on the project depends upon the number of loads a truck can make per day and the number of loads needed to have the proper amount of stringing progress per day that is required.  

The equipment used to go down pipeline right of ways, on the surface, appear to be typical tractor trailer rigs.  However they have several modified features that enable the rigs to travel down the right of way and minimize the potential damage to equipment and providing for improved access to points on the right of way.  This entails rigging the tractors and trailers for better ground clearance, raising the oil and fuel lines to prevent them from being torn by stumps or branches on the right of way.  The single point suspensions used on the pole trailers allow the trailer to go over sharp up turns and down turns on the right of way while still supporting the weight of the pipe.  Towing of the equipment is completed safely because of the tow hitches that are installed on the tractor and trailer.  Drivers are trained in much greater detail so that they can safely perform the tasks that are required in the harsh and hazardous environment.  We often say that what we do is very hazardous but it can be done safely if every little detail is taken care of along the way.  This requires 100% attention to the task at hand so that nothing goes wrong.  Often the terrain on the right of way becomes so difficult that the stringing trucks can not deliver on the right of way.  In these cases other types of delivery methods are utilized, such as, high floatation vehicles, push sites and in rare occasion’s helicopters.
