Saft batteries for hybrid ships ABB

The cable ship ABB will be the first in the world in which they will be integrated with the new system battery Li-Ion new generation with high power cooling liquid Saft.
Saft, a manufacturer of advanced technology batteries for industry, has won a contract with ABB Marine to supply its battery system Super Phosphate ™ (SLFP) specialized high-power, cooling liquid lithium-ion batteries for new and innovative cable ships hybrids. Saft batteries provide efficient energy storage for backup charging cable and assistance of propulsion, which helps reduce fuel consumption of the vessel by 27% and reduced maintenance compared to current systems traditional AC.

ABB High Voltage Cables has commissioned the most advanced I cable ship in the world to increase the capacity of its operations submarine cable for laying of AC / DC cables and optical fiber and repaired anywhere in the world, while greater efficiency is achieved and precision. SALT 306 design vessel CLV, which is the largest of its kind in the world, measures approximately 140 x 30 meters. Is being tailored to meet the specifications of ABB in the Kleven shipyard in Norway. Delivery is scheduled for 2017.

The system of diesel-electric propulsion will be pushed propulsion engines for six high-speed Caterpillar 3516 (with about 2 MW each) which act as generators for three engines Azipod CZ 980 to 1,900 kW. Propellers, each with a thrust of more than 34 tonnes, will allow operations DP3 (dynamic positioning systems). The energy is converted to electricity through the direct current network ABB Marine, allowing operate variable speed to optimize engine operations.

The cable ship ABB is the world’s first to be equipped with a system of marine battery Saft’s next-generation technology with cell cylindrical liquid-cooled lithium-ion Super Phosphate ™ (SLFP). This approach offers significant advantages over other technologies for lithium-ion cold air in high power applications, including: a temperature range wider operation; greater capacity for cycling; better temperature control of the battery level; improved tolerance for abuse; safer compared to other lithium-ion chemistries.

The battery system capacity of 70 kWh Saft is mainly used to help transfer cable from the dock to the turntable of the ship. These operations are mainly promoted from the coast to the cable ship because the ship diesel engine must be turned off to meet new emissions regulations. However, if the battery supply is interrupted it can support a load of up to 800 kW for 10 seconds, which is enough to bring the turntables to a safe and controlled stop.
