B. Installation of the V-Sup
Step B.1. Preparation of construction location:
−Make sure the construction area is visibly marked and the transport and emergency routes are clearly indicated.
−Make sure the surface on which the V-Sup will be installed is levelled, the maximum slopes should be accepted.
Check the right-of-way (pipeline route) for any slopes.
−Make sure the surface on which the V-Sup will be installed is flat, unevenness in the terrain of maximum 50 mm
are acceptable. Unevenness larger than 50 mm should be levelled out properly.
−Make sure the surface on which the V-Sup will be installed is free of ice, snow, oil, mud, algae, or any other
substances that have a negative influence on the friction.
−Make sure the surface on which the V-Sup will be installed is free of obstacles (such as wood, stones, gravel
or any other obstacles).
−To ensure a safety envelop large enough, the use of the V-sup is recommended within a temperature window
of -30°C up to +45°C. (-22°F to 113°F)
Step B.2. Installation of Stackable Beams
−Each V-Sup Stack will be assembled from stackable beams, placed on top of each other. For every pipe, at
least two V-Sup stacks are necessary.
−Make sure all beams are free of ice, snow, oil, mud, algae, or any other substances that have a negative
influence on the friction.
−Make sure the V-Sup segments are not damaged, deformed or worn down.
−Make sure the recesses in the beams lock precisely into each other.
−The alignment of the V-Sup stacks is of vital importance for the safe functioning of the system. The V-sup stacks
needed for one pipe should be aligned parallel.
−To give the best support for the pipes, the V-Sup stacks have to be placed at a set distance according to the
pipe length and the amount of V-sup stacks needed. The distance is prescribed as a percentage of the pipe
length. Figure 7 will show the prescribed distances with 2, 3 and 4 supports.
