LNG DSME launches GTT


competitor GTT chairman and CEO Phillipe Bertorottiere said that his company welcomes the competition that will come from the development of the ACT-IB (Aluminium Cargo Tank – Independent type B) LNG cargo containment system by Daewoo Shipbuilding and Marine Engineering (DSME). However, Mr Bertorottiere questioned whether the


new technology would pose an immediate threat to the established systems produced by GTT. “It has a long way to go before it is established as proven technology, there is a big difference between the concept and the working and adapted investment,” explained Mr Bertorottiere. DSME announced that it had developed the world’s


largest independent-type LNG cargo containment system, which it says is essential for LNG carriers and LNG-FPSO (Floating, Production, Storage and Offloading) vessels. According to DSME the new containment system has


the largest storage capacity among the independent type containment systems. DSME will apply this technology to its LNG-FPSOs, which produce over two million tonnes of LNG annually. This new system can contain a maximum of 210,000m3


containment system of about 80,000m3 than 150,000m3


of LNG, three times more than a conventional or 50% higher


, which is an equivalent amount to that


consumed daily in Korea. DSME also said that the development of the its


new system meant that “DSME no longer has to pay a technology royalty to French or Japanese LNG containment system patent holders.” Te company had complained that high royalty payments made the acquisition of LNG containment technology very costly. DSME said last year that it “no longer recommended” GTT’s MKIII containment system as the secondary barrier was very weak and “owners were very worried” about the bonding on the system. Dismissing these concerns Mr Bertorottiere said that this was “negative marketing”. He said that DSME uses

the No96 system and therefore it was being negative about the MKIII, however, Samsung heavy Industries uses the MKIII and they are happy with it, “there are no bonding problems”. “I wish they would use positive marketing instead,” said Mr Bertorottiere.


Environment GL issues the first


EEDI certificate Germanischer Lloyd said it issued the first Energy Efficiency Design Index (EEDI) certification in June. Te certificate was awarded to the Hapag Lloyd container ship, the 8749TEU Vienna Express. Te EEDI certificate was issued in accordance with


the voluntary EEDI guidelines, MEPC.1/Circ.681 and 682 of the International Maritime Organization (IMO), said GL. Te EEDI value attained Vienna Express is significantly


better than the present average score for vessels of a similar size (based on Lloyds database), underlining the high energy efficiency of the vessel’s design, said GL.

Te IMO is looking to reduce emissions from shipping


through EEDI which was conceived as a future mandatory newbuilding standard. Te EEDI compares theoretical CO2


emissions and transport work of a vessel (gCO2 /


(t*nm)) and will eventually be benchmarked against an IMO-set requirement. Verification of the EEDI value was conducted through


the compilation of a technical file which summarised all the relevant technical data, and documents and the calculation procedure towards the final EEDI score. However, GL said: “Some issues in this context require more attention from the IMO and, therefore, identified items have been forwarded to the German flag state administration for possible consideration at future IMO meetings.” GL did not elaborate on what these items might be.
