Trelleborg has released a statement claiming that its fluid handling operation has won the EN1474-2 accreditation following the development of a new hose design. The hose is used for transferring LNG between carriers and floating terminals, and is the first hose of its type to receive the accreditation.
With this hose, LNG transfers can be executed with 100 – 150 m between the vessels. This is opposed to traditional side-by-side operations, in which the vessels can be as close as 5 m. This additional distance can enhance the overall safety of the LNG transfer process. Furthermore, the added distance means that transfer operations can be carried out in challenging weather conditions, leading to increased efficiency.
The Marketing Manager for Trelleborg’s oil and marine hoses, Vincent Lagarrigue, said: “For our customers, it is reassuring to know with certainty that all possible measures have been taken to eliminate the risk of LNG transfer becoming unduly hazardous or being halted by the elements. This accreditation can be seen as a ringing endorsement of the safety of our products and sends a strong message to the market.”
The new configuration features a 0.5 m inner dia. and 20 barg working pressure cryogenic floating hose. This was developed by Trelleborg and Saipem, and consists of a floating hose based on a hose-in-hose concept. In this a concept, an outer rubber marine protective hose houses an inner LNG cryogenic composite layer (a concept that has already been established in LNG ship-to-ship operations).
The hoses will be used in demanding environments, so thorough tests were carried to ensure their suitability. In order to meet the requirements of the EN1474-2 standard, Trelleborg carried out tests on a number of full size hose prototypes in static and dynamic conditions. The tests, which were mostly carried out in cryogenic conditions, proved the ability of the hoses to handle the extreme conditions.
