Lainapeite Provides Weather Equipment for Oil Professionals

Mobile halls by large Scandinavian holding NSS, segment leader on the European market, are familiar in Russia, Baltic states, Germany and UK. Lainapeite, Russian branch of the holding, was established in 1998. Oil and Gas Eurasia talks with Lainapeite president Janne Oksanen on how the company’s products make life of oilmen at remote fields more comfortable.

Oil and Gas Eurasia: Please tell us about specific features of fast-assembly structures?
Janne Oksanen: First of all, fast-assembly structures are easy to transport and they can be assembled almost instantly. The important feature here is the structure’s mobility – the opportunity to move the hangar and to change its dimensions. The structure consists of standard elements, with certain size and parameters. The assembly is done similarly to child’s meccano set  – either separate parts or entire blocks can be joined together. The more comfortable environment results in better productivity, while equipment and materials are stored in weather-proof locations.

OGE: Where these technologies can be used, what’s their place within oil industry?
Janne Oksanen: The hangars are specifically designed to shelter personnel and equipment employed at remote fields. Another significant direction is a temporary storage segment, i.e. temporary storage for drilling equipment. Notably, moderate-size hangars need no special equipment for assemblage – everything is done manually. Tent structures have been used as vent cover for fuel storage tanks. Such covers reduce heat rate, cutting down vaporization level.

OGE: When did the company present its hangars to Russian market?
Janne Oksanen: Aggressive promotion of NSS Hall product on the Russian market was started in 2007. Striving to cater for the clients as much as possible, we’re now preparing new differentiated products (such as dismountable hangars) in parallel to existing goods.

OGE: What is the structure of NSS Hall hangars?
Janne Oksanen: Dismountable constructions NSS Hall are basically the frames made of painted steel trusswork, lined with PVC fabric. Roofing and walls of NSS Hall fast-assembly hangars are made of single fabric, for lifecycle-long protection from the leaks. Standard width of NSS Hall hangars is between 10 and 40 meters inclusive, with no extra support pillars. Length can take any figure proportional to the step of trusswork. The company also takes individual orders. Optionally we can provide hot zinc-plating for even more compact transportation with minimal packing, for better corrosion resistance and for longer service life. Special tent fabric is manufactured for normal usage in temperatures of minus 50 degrees Celsius, and even minus 70 degress Celsius. The fabric has been treated with agents preventing flame spreading (flame retardants), and bacteria and mold generation. These advantages altogether provide safe and durable service life.

OGE: What are the advantages of NSS Hall hangars compared to traditional metallic constructions?
Janne Oksanen: Firstly, and most importantly it is mobility. You can easily erect NSS Hall, easily dismantle and assemble it in a new place. Usage of light guarding and optimization of structural concepts resulted in lower weight of the hangar. Tent fabric five times lighter than  profiled steel sheets.
The roofing is made of transparent material, which saves electricity during day time. Metallic hangars require electricity all day long.
Importantly, tent hangars are positioned as temporary structures and thus fall into the category of non-permanent property. This means streamlined coordination with local authorities and fasttrack acquisition of installation permit compared to hangars from  profiled steel sheets, which are legally permanent structures.
Also, unlike with tents, taking down  profiled steel sheets could deform them. The holes remaining after dismantling the structure disfigure appearance and structural integrity of assembled steel guards.
Reusability of tent constructions enables the company to offer a flexible cooperation system. There’s no need to invest sky-high money in acquiring a hangar – you could easily rent it out for the period required.

OGE: In what cases renting is preferable?
Janne Oksanen: Temporary structures present good solution for fixedterm using hangar; rental is more efficient price-wise than installation of a permanent structure. Thanks to rental condiitions, you have opportunity to return hangar back or change it to new one. We offer an option of shifting the payment for delivery, assembly and disassembly work to the end of payment period. This reduces the cost of starting a project. Another option is to spread the cost of assembly and disassembly over the entire renting period. This removes the need to take up expensive credits, paying high percentage rates. The acreage of the rented premises can be easily changed according to the circumstances as the frames have modular, easy for assembly/disassembly and transportation structure.

OGE: How long is hangar’s service life?
Janne Oksanen: The fast-assembly constructions of NSS Hall – with proper exploitation and servicing – tops 30 years. This is the known real service life for static usage. Transportation and change of dimensions are possible within 10 years’ period. The hangars look aesthetically pleasing due to wear-proof tent and high quality anticorrosive treatment for the metal framework.

OGE: Isn’t tent less sustainable to mechanical damage than metal sheets?
Janne Oksanen: Mechanical damage of the tent is easily fixed, retaining the strength balance and appearance of the construction. Flexibility of architectonic PVC fabric means that it remains intact in the conditions which would have damaged other materials. Significant mechanical damage to a  profiled steel sheet would require its change as seamless repair is impossible. Patching will not restore structural integrity of the steel hangar and with time will result in leaks. Unlike tent,  profiled steel sheets, regardless of dye or galvanization, is prone to scratching, rusts with time, its coat comes off easily. Roofing and walls of NSS Hall fast-assembly hangars are made of single fabric, for lifecycle-long protection from the leaks. With time, water finds way inside the building through in the places of sheet joints and under the washers of self-drilling screws.

OGE: How common are such structures in other countries?
Janne Oksanen: Hangars with wall and roofing guards from architectonic fabric are used all over the world in manufacturing, logistics,  military, construction  and agriculture . Usually they are used for storage of cargo and equipment, as a human shelter, temporary repair facility, etc. Other utilization segment is sports-related construction projects, where the tent can be used for covering the sport fields. All materials used are certified, including as the materials safe to use in premises for children.
