as eliminating the possible leakage of hydraulic fluid into the sea. But the challenge is to provide enough power to operate the choke at depths of up to 3,000 metres when it’s not practical to run a cable that will meet the high peak power demands. Saft Li-ion batteries provide the ideal solution: • Saft cells meet all technical, commercial and schedule challenges • Compact cell size enables battery to fit within the confined space of the choke baseplate • Li-ion technology ensures a long service life in float charge conditions • Dual redundancy is provided by two batteries controlled by a battery management system Saft’s lithium-ion (Li-ion) VL cells have overcome significant technical challenges to provide reliable operation for subsea oil and gas systems.
