LLC "SP VIS-MOS" is the leader on the horizontal directional drilling (HDD) market in construction of the pipeline crossings of increased complexity level.
Horizontal directional drilling (HDD) or directional drilling (DD) is an operated trenchless technology of pipelines construction under different natural and artificial obstacles (rivers, dams, railway lines, highways and so on). The horizontal drilling method is ecological so that by its use loading on the environment is minimal.
Comparing horizontal drilling method with traditional trench technology of the underground pipelines construction the horizontal drilling has an amount of other significant advantages, namely: less temporal, financial and labor costs, as well as possibility of the pipeline construction in places where trench method is not applicable.
During its existence the LLC "SP VIS-MOS" has fulfilled 500 000 linear meters of pipelines and cable crossings of different complexity level in field and urban conditions. Many of the crossings remain globally unparalleled.
The company has the biggest rig fleet in the world for the horizontal directional drilling (HDD) or directional drilling (DD) among the companies of this profile. The geography of drilling works extends not only for Russia but also abroad: Germany, Greece, India, Sudan, and Kazakhstan.
"SP VIS-MOS" LLC is directly involved in realization of international projects.
"SP VIS-MOS" LLC renders services in horizontal drilling of obliquely directed boreholes.
Horizontal directional drilling (HDD) is a technology of 21st century.
It is necessary to provide dynamic development of cities and prompt development of engineering and technologies, branched networks of underground communications (pipelines, cable networks) of different purposes.
By the modern high normative technical requirements to the quality, terms and efficiency of works by the construction, operation and repair of all types of the underground communications just trenchless technologies can provide safety, reliability and durability.
Horizontal directional drilling (HDD) or as it is also named directional drilling (DD) at the moment is an irreplaceable method by the underwater crossings and underground crossings construction.
Trenchless construction is a serious economic reserve for the oil and gas branch and communication branch.
Traditional trench method of pipelines and cable networks laying is characterized not simply by great amount of earthmovings, man power and long terms of construction, but first of all, by hardest influence on the environment in field conditions and creation of serious inconvenience for people in an urban setting.
Horizontal directional drilling allows avoiding all these problems in a single step. Technical means and methods used in the process of this trenchless technology simply allow making a puncture under an obstacle, expand a borehole to the size a little larger than the pipeline's diameter and at the final stage to pull through the joint in a borehole.
Drill rigs for directional drilling are equipped with components similar to the components of drill rigs for oil-well drilling with the main difference that boring machine for horizontal drilling is equipped with inclining stringer instead of vertical rig. Drilling is carried out almost in a horizontal direction that allows construction of the underwater crossings and underground crossings.
Financial and economic benefits from usage of the HDD technology
cost reduction by the pipeline construction at the expense of the terms reduction for the works fulfillment so that by the HDD method high-tech drilling facilities are used with high speed of deepening;
at the expense of high workability of the HDD method minimal involvement of labor forces is necessary;
construction cost reduction and widening of the works geography by means of the full independence and mobility of drilling facilities, that allows working in remote and hard-to-reach areas, where there is no power supply;
In the presence of current power supply sources energy consumption is minimal at the expense of economy of all used in the drilling facilities machines and units;
Operational risks and expenses for maintenance are practically reduced to zero at the expense of a deep pipelines laying (up to 100 years guarantee).
Production and technical benefits by the usage of the HDD technology
In field conditions the construction of the following crossings is possible:
underwater crossings under navigable rivers, fishery water basins, old-growth forests and reserved wooded areas, agricultural objects of special purpose;
crossings in hard soils (solid rocks, rubbles, limestone, quicksand and so on);
crossings by the big level difference.
In an urban setting the crossings construction is possible:
under the conditions of large-scale housing construction system under highways, street railways, squares and parks, railways, runways;
to supply service lines to the production buildings in the territory of operating enterprises;
to create (within natural bend of drill rods) nonlinear path of a borehole under the conditions of branched out network of service lines at the expense of technological possibility;
without traffic interruption of all types of above-ground transport hereupon the necessity of organizational and technical coordination with various urban services falls off;
with guaranteed safety of urban environment, historical places, park zones and separate green plantings, automobile and railway roads.
Social and ecological benefits by the usage of the HDD technology
Minimization of negative influence on conditions of people inhabitance in the zone of the works fulfillment;
coast and bed safety, preservation of landscape and ecological balance in places of the works fulfillment.
