The major advantage of using FiGS on any type of subsea engineering, design, modelling, structure is the large amount of accurate information obtained project management, inspection, over a relatively limited extent of time. Also, because FiGS sales, marketing and management in data is combined with detailed CP models developed using the sector since 2001.
