Product Introduction
1. Vessel Overview
HYSY707 is China's first domestically self-developed all-in-one geotechnical & geophysical survey vessel under the TUNA S S600 platform, delivered in 2015 with full CCS certification and CLEAN environmental notation.
This compact DP2 vessel is highly recognized among Australian offshore mining & marine exploration contractors; multiple Australian mineral survey firms have conducted detailed technical evaluations and shown strong procurement interest due to its balanced cost and multi-functional capability for shallow-to-medium seabed mineral prospecting, underwater expedition and coastal geotechnical works.
Equipped with full drilling, sonar and sampling suites, it operates worldwide under unrestricted navigation standards, perfectly matching small & medium marine operators' business demands.

3. Core Competitive Advantages (Highlight Australian Market Fit)
- Cost-Friendly Compact Size for SMEs, Favoured by Australian Buyers Much lower total investment and daily OPEX than large saturation diving vessels. Multiple Australian coastal mineral survey SMEs have shortlisted this model, as it fits medium-small corporate capital budgets without relying on giant mining groups. Shallow 5.85m draft enables berthing at regional Australian minor harbours without deep-water terminal limits.
- Dual Function: Seabed Mineral Prospecting + Underwater Expedition Integrated geotechnical drilling system collects seabed ore core samples, geophysical sonars map mineral-rich strata; reserved deck space fits sightseeing ROV, underwater camera arrays and exploration equipment for marine adventure, relic search and ecological survey — two steady revenue streams to lower vessel idle risk for Australian operators.
- Proven Global Operation Track Record (Overseas Job References) Completed formal geotechnical projects in the Gulf of Mexico and multiple Southeast mineral blocks, with stable performance under rough offshore sea states similar to Australia’s continental shelf waters. Domestic full-set equipment cuts maintenance downtime and spare-part costs for overseas fleets.
- DP2 + Optimized Seakeeping for Australian Rough Coastal Seas Passive anti-roll tanks and CFD-optimized hull greatly reduce rolling motion during continuous sampling operations. DP2 positioning maintains stable station keeping on mineral blocks without frequent tug assistance, cutting Australian port operation fees.
- Full Environmental Compliance for Australia’s Strict Marine Rules CLEAN class notation, low-emission electric propulsion and zero-discharge sewage system fully satisfy Australia’s EPBC marine protection regulations, avoiding port detention and environmental fines.
