Trelleborg’s oil and marine hoses operation recently launched a dedicated seawater intake hose engineered specifically to meet the unique requirements of floating liquefied natural gas (FLNG) extraction facilities.

The new Swiline range of hoses from Trelleborg can be used in lengths of 600 meters or more, enabling the use of seawater from greater depths, in temperatures up to 20° C cooler than water at the surface. Swiline hoses are fully certified to the API 17K standard, which certifies up to 30 years of maintenance free service life with a safety factor of 10. The seawater intake hoses are designed to deliver optimum performance in even the most demanding process conditions. Employing a unique design incorporating an integrated bending stiffener with a continuous inner liner and rubber outer cover, the hoses minimise the risk of corrosion while offering optimal thermal insulation. The combination of steel cables in a rubber matrix minimises creep and offers typical tensile strength as high as 1,600 tonnes for 40 inch ID hose.

The Swiline range has already been fully qualified and specified for the USD $12.6 billion Shell Prelude project – the first FLNG located in the Timor Sea, off of Australia, with production scheduled to commence in 2017.
