LNG Hose Design
The key characteristics of the ContiTech Oil & Gas LNG transfer hose are its unprecedented performance on tensile load and pressure capability, flexibility and bending endurance. In addition, the revolutionary end fitting designs overcome the limitations of many existing composite hoses. All these factors combine to allow easy and controlled offshore handling and reliable operations when needed most.
This has been achieved through an extensive programme of research, development and testing, and the unique application of new and innovative techniques, materials and components to existing and established composite hose technology.
Qualification & Testing
ContiTech Oil and Having received a Statement of Endorsement for the technology from DNV GL in August 2012, The Dunlop LNG Transfer Hose has undergone an extensive testing programme, incorporating EN1474-2 standards, which takes the hose to its design limits and beyond, both at cryogenic and ambient temperatures.
The base hose design has previously been Type Approved by Lloyd’s Register for offshore marine service.
