Cryoline LNG System ‘Opens a New Door to LNG Accessibility,’
Smaller Hoses Suitable for LNG Bunkering Are In Development

Sweden-based Trelleborg has introduced a new Cryoline LNG brand system for cryogenic liquid transfers it says “opens a new door to LNG accessibility.”

Trelleborg’s ‘Cryoline LNG’ brand floating cryogenic hoses allow vessels to be moored nearly a third of a mile (up to 500 meters) away from a shoreside facility, permitting LNG transfers in deeper waters without the need for complex infrastructure.

A smaller-diameter variant suitable for LNG bunkering is in qualification now.

Trelleborg’s “hose-in-hose” equipment allows liquefied natural gas to be transferred from shore-to-ship (or ship-to-shore) without the need for costly complex infrastructure: the floating Cryoline LNG hoses effectively take the place of an LNG jetty.

“The cryogenic floating hose system enables rethinking of the conventional wisdom in LNG ship-to-shore transfer for regasification, liquefaction and terminal storage, as well as for gas power generation projects,” the company says.

‘A More Viable and Innovative Alternative’

“It also offers a more viable and innovative alternative to existing ship-to-ship transfer systems, ensuring higher safety and operability standards through optional increased distances between vessels… “Operators have a greater choice of configuration, more flexibility, and a less strenuous replacement to conventional ship-to-ship systems.

The Cryoline hose-in-hose transfer system “is truly a ‘game changing’ technology, which will contribute to making it easier and cheaper to transfer LNG,” Trelleborg global fluid handling director Gianni Sicuro said in a release.

Up to 80% in Operational Savings

“Trelleborg’s cryogenic floating hose is the only solution that could potentially offer up to 80% in operating cost reductions compared with traditional transfer solutions, equating to significant savings,” Sicuro said.

“The Cryoline floating hose was more than seven years in development and validation, and is the first floating hose of its kind to receive the coveted EN1474-2 accreditation,” said Vincent Lagarrigue, head of product management. “Meeting the standard means that we are part of a transformation in the way that LNG can be handled.

“It will help make safer ship-to-ship transfer possible at a potentially lower cost, and in particular, in the small-scale LNG market, it can fulfill the operators’ desire to open up new markets in remote areas and negate the needs for costly on-shore infrastructure.

Bunkering Variant Is in Development

“We expect this hose-in-hose transfer system to be truly revolutionary,” Lagarrigue said: “LNG can be transferred directly without the need for infrastructure such as jetties.”

Trelleborg’s ‘Cryoline LNG’ hose includes an inner cryogenic layer, insulation materials to reduce heat loss and ensure hose buoyancy, and an outer protective marine hose using conventional flexible bonded hose technology.

Trelleborg says it tested several full-scale hose prototypes in both static and dynamic conditions at its R&D facilities in Clermont-Ferrand, France. Most of the tests took place in cryogenic conditions at -196 °C/-321 °F, the company says, and the floating hoses “were able to demonstrate their ability to withstand fatigue resistance in even the most hazardous conditions.”

Current Cryoline LNG hoses, with inner diameters ranging from 16 to 20 inches, are designed for large-volume LNG transfers. Trelleborg is also developing a non-insulated hose, to be available with diameters of two to ten inches. “This hose will be more applicable for bunkering,” Lagarrigue told HHP Insight.
