18Maritime Reporter & Engineering News Great Shipsof 2011Even as the maritime i0ndustry struggles to shake the hangover of a global world economic meltdown, mar- itime companies ? forced by legislation and the need to adopt modern, efficient tonnage ? continued to churn out innovative new designs for the movement of cargo and people around the globe. Sonangol SambizangaLargest Steam Turbine Driven LNG Carrier The Sonangol Sambizanga, the largest steam turbine driven LNG carrier in the world, was deliv- ered to Sonangol USA Companyby Daewoo Shipbuilding and Marine Engineering Co., Ltd. (DSME)which is building a series of three vessels, each measuring 291 x 43.4 m. The vessel?s cargo area consists of four cargo tanks with a cumulative capacity of 160,500 cu. m. The vessel is designed environmentally friendly, excluding harmful materials, such as toxic smoke producing material, CFC, HCFC & Halon to name a few, and by preparing the list of potentially hazardous materials in accor- dance with IMO assembly resolution 962 ?IMO Guidelines on ship recycling.? Additionally, a silicon antifouling paint was used to enhance energy efficiency by reducing friction resistance during voy- ages. The ship is robust with a design fatigue life of 40 years.
