Application Examples

Tank supports for LNG carriers

Lignostone^® is a laminated densified wood which offers exception properties, making it ideal for use as tank supports (picture), chocks, fixed blocks and sliding blocks in LNG transport vessels. Low thermal conductivity, low weight, a low coefficient of friction and an ability to withstand high mechanical loadings are some of the advantageous properties that Lignostone^® has. Beside this the material is suitable to operate in environments with temperatures from -196 °C to +90 °C (-320 °F to 194 °F). Lignostone^® is approved by LR, BV, NKK, GL, DNV, M.W.Kellog, IHI and JMU. You can be sure of an excellent quality.

Cryogenic insulation in LNG and LPG tankers

BU: Put your trust in globally proven quality: Lignostone^® cryogenic has already been used in international shipping for decades to provide cryogenic insulation in LNG and LPG tankers – manufactured here as a tank support based on a customer drawing.

Construction elements

Lignostone^® Transformerwood has an excellent reputation in the international transformer industry. The premium material combines outstanding electrical and thermal insulation properties with a very good oil intake, low weight and high resilience. Typical components include pressure rings, platforms, pressing beams, pitch rings, pressure segments and connection elements.
