Safety & Recommendations Composite Hoses for LNG transfer operations

LNG SHIPPING & TERMINALS WEBINARAugust 4, 2021

Part of

Gutteling was founded by Mr.Peter Gutteling in 1990.

In March 2021 Gutteling Group has been acquired by Trelleborg Group.

Gutteling is nowadays World Leader in the production of Composite Hoses for

critical applications like:

• Ship to Ship operations

• Ship to Shore operations

• Heavy Duty Marine operations

Gutteling Composite hoses can be used for a wide range of products:

• Oils

• Petrochemicals

• Chemicals

• LPG (@ -104°C)

• LNG (@ -164°C)

Slug flow during liquid freeing

F = 2.4*A x 0.5 ρ U2

When liquid is poled in a hose and the system is started up this pool due to wave formation on the pool can be pushed as a slug (leaving bit of liquid behind) with high velocity through the hose• This may leads to very high forces on bends• This may leads to high shear forces at the wall (0.1 bar/m)• This may leads to very high forces on other components in the system

- Avoiding pressure peaks

- Avoiding LNG slugs in gas

- Avoiding RPT (Rapid Phase Transition)

- Avoiding high gas flow velocities

- Avoiding expansion waves in the system

Liquid freeing and purging

• Design pressure upgraded to 21 bar up to 10”

• Hoses delivered for continuous LNG transfers• Hoses delivered for Ship Shore interfaces

• 16” hoses developed, not been certified yet

• Longer hose lines to 40 – 50 meter

• LNG hoses with additional Thermal insulation

• Detailed LNG flow dynamic investigations

Future steps…….
