These multifunctional vessels are designed for tasks including deep-sea ROV and AUV operations, and scientific research including seismology, geology and marine biology. The hull is designed for fuel efficiency and minimised slamming risk.
Close attention to the reduction of in-water noise sources is the result of extensive testing to determine the best interaction between the hull and the propellers. On board, noise and vibration levels are effectively minimised by diesel electric systems. All designs conform to the most stringent international environmental classifications.
