Our diving and in-water survey operations are approved by Lloyd's Register, DNV, Bureau Veritas (BV), ClassNK (Nippon Kaiji Kyokai), and ABS. We hold valid certificates of approval for in-water surveys on ships and mobile offshore units.
Yes. Our emergency response diving team is available 24/7. We have responded to critical underwater hull breaches, propeller damage, and emergency sealing operations at short notice across Aqaba, Basra, and UAE ports.
Regular hull cleaning and propeller polishing reduces surface roughness, restores vessel performance and service speed, diminishes hydrodynamic drag, optimizes propeller efficiency, and reduces fuel consumption — resulting in significant cost savings over time.
Yes. Every underwater inspection is documented with full photographic records, CCTV/DVD footage, and detailed technical reports covering hull condition, paint coating status, cathodic protection assessment, and all damage observations. These reports are produced in the format required by the relevant classification society.
