The new membrane elements has been tested onboard Langh Ship’s M/S Marjatta from the first half of 2017…

The maritime industry has taken a step closer toward ballast free shipping with the award of a new approval in principle (AiP) at Marintec China on Tuesday. GTT and Dalian Shipbuilding Industry Co. Ltd (DSIC) received AiP from Lloyd’s Register (LR) for their ballast-free shipping solution, a 30,000m³ B-FREE liquefied natural gas (LNG) carrier design, which the developers say could combine environmentally-friendly features, increased efficiency and lower build and operating costs. “While we are still in the initial stage of the project and the design is subject to ongoing change, the initial results are indicating that we will meet our goal of having a ballast-free ship that is equal to, or better than existing conventional designs,” said Ma Yingbin, Vice Chief Engineer, DSIC.

GTT said it has received an order from Samsung Heavy Industries (SHI) to equip a new Floating Liquefied Natural Gas unit (FLNG), reportedly the second biggest in the world.   The new FLNG, with a capacity of 238,700 m3, will integrate eight LNG tanks equipped with the Mark III membrane containment system. The unit will be built at SHI Shipyard, based in South Korea, on behalf of the Oil and Gas company ENI (Eni East Africa SpA) and its delivery is scheduled in 2021. This FLNG will be operated off the cost of Mozambique.   In addition to this new order, the GTT membrane technology has been selected to equip the three FLNGs already ordered in the world. These units are being equipped with the NO96 system as well as the Mark III system.

GTT said it has received an order from Hyundai Heavy Industries to equip a new LNG carrier with its Mark III Flex containment system.   Hyundai's shipyard based in Ulsan, South Korea will build the vessel of 180,000 m3 on behalf of the Norwegian shipping company NORSPAN LNG XI AS (Knutsen). Delivery is scheduled in 2019.    Knutsen is a longstanding owner of LNG carriers equipped with membrane technology, with 10 vessels of this type.   GTT records the first LNG carrier order of the year. With its Mark III Flex containment system, GTT said it provides efficient insulation solution able to reduce the daily guaranteed boil-off gas rate to 0.085 percent of tank volume. The Mark and NO ranges have been designed to meet all the transport and storage requirements of liquefied gases.

Envirocleanse LLC recently submitted a Letter of Intent to the U.S. Coast Guard and the International Maritime Organization (IMO) indicating that the company will apply for Type Approval of its patented Envirocleanse inTank ballast water treatment system (BWTS).

Lloyd’s Register specialists have issued GTT an Approval in Principle (AIP) for a membrane cargo containment system (CCS) for bunker ships to allow an increase in vapor pressure of up to 2barg. The AIP follows a joint research and innovation program between GTT and LR investigating cargo containment behavior, looking at strength aspects in various applications, sizes and at different pressures. The close collaboration between Lloyd’s Register and GTT experts, through workshops using experimental and analytical results and data on internal pressures occurring in LNG tanks, studied the maximum compressive strength of the containment system on LNG carriers.

GTT, a designer of membrane containment systems for the maritime transportation and storage of liquefied natural gas (LNG), has signed a Framework Partnership Agreement with CERN (European Organization for Nuclear Research) for the engineering and the construction of several tanks (cryostats), to contain liquid argon for experimental purposes.
