MORE+ Video Creating solutions together VSL's corporate movie → WATCH MORE + VSL's Offer Technology Applications The most efficient structural solution for LNG and LPG applications When its temperature is lowered to -161°C, natural gas liquefies and takes up just 1/600th of the volume it does in its gaseous state. This makes liquefaction the ideal solution for transporting and storing natural gas located in areas far from pipeline infrastructure. LNG must be kept cold to remain a liquid, independent of pressure, and modern LNG storage tanks typically provide full containment and comply with extremely stringent safety regulations. They normally feature a prestressed concrete outer wall and a high-nickel steel inner tank, with extremely efficient insulation between the two walls. Post-tensioned concrete is the solution that provides a safe outer containment structure as it reduces crack widths to provide a safeguard in case of failure of the inner tank. VSL is the most experienced contractor in the tank construction industry and has a portfolio of more than 60 reference sites worldwide. Its construction of containment structures spans the last 30 years, with the scope varying from the supply of post-tensioning, through PT design and supply, to the provision of the forming systems required to implement the structure’s design. MORE+ VSL products and services VSL has an extensive array of related engineering services for LNG and LPG containment structures. In particular, VSL’s scope includes: Design and detailing of the post-tensioning layout to provide compressive stresses in the concrete membrane in accordance with the designers’ requirements Supply and installation of post-tensioning whose performance is maintained even at cryogenic temperatures Design and supply of specialised formwork for construction of the walls, using VSL’s climb-form, slip-form, jump-form or guided gang-form systems All related construction works, such as rebar and concreting, as part of a complete turnkey package Associated services : VSL’s Heavy lifting technology, using strand jacking to install the roof VSL’s repair, strengthening and preservation services to improve the longevity of existing tank structures Monitoring schemes to control the behaviour of the structure during construction or during the facility’s service life Blast protection for critical infrastructure adjacent to the LNG/LPG tanks Advantages of VSL’s services Extensive experience VSL is recognised as an international leader in LNG and LPG tank construction Compliance with international standards VSL’s post-tensioning systems comply with ETAG requirements and have been tested under cryogenic conditions Full encapsulation Superior corrosion protection for tendons Enhanced efficiency VSL's PT-Plus® ducts offer improved force distribution along a tendon’s length and can also be used to provide a tendon with full encapsulation Versatility Five different types of anchorages to suit varying project requirements Unique AF Anchorage Allows the use of vertical tendons without the requirement for a stressing gallery Contributing to sustainable solutions VSL post-tensioning systems enhance the safety of LNG/LPG containment structures, making the concrete walls airtight. Post-tensioning allows for a reduction in the thickness of structural elements and the amount of steel reinforcement, thus saving materials and therefore reducing the CO2 footprint of their construction.
