The fully enclosed environmental-friendly offshore concrete mixing vessel is a highly specialized marine construction support asset specifically engineered for offshore bridge construction projects, offshore wind farm development, marine infrastructure construction, island reclamation support, port expansion operations, offshore caisson construction, and large-scale offshore concrete production activities. Designed around a fully enclosed and environmentally controlled floating production configuration, the vessel combines high-capacity automated concrete production capability with advanced environmental protection systems, integrated material handling arrangements, and offshore positioning capability suitable for continuous marine construction support operations in demanding offshore environments.
The vessel is designed specifically to address the operational limitations associated with traditional land-based concrete supply systems utilized for offshore construction activities. Conventional offshore projects frequently encounter logistical difficulties in transporting large concrete volumes from shore-based batching plants to offshore construction sites. To address these operational challenges, the vessel incorporates a self-contained offshore concrete production platform capable of delivering continuous high-volume concrete production directly at offshore project locations while maintaining operational stability, environmental compliance, and production efficiency.
Principal dimensions of the vessel measure approximately 110.8 m LOA with approximately 39.98 m moulded beam and approximately 6.18 m moulded depth. Operational draft is approximately 3.6 m, allowing the vessel to operate efficiently within nearshore and offshore construction environments while maintaining substantial onboard storage and production capability. Deadweight capacity is rated at approximately 6,850 Tons, supporting significant onboard material storage capability for extended offshore production campaigns. The vessel is additionally configured to accommodate approximately 27 POB, including operational personnel, technical support staff, and offshore project management teams.
The vessel incorporates a fully integrated offshore concrete production arrangement centered around dual fully computer-controlled 3 m³ concrete mixing systems supplied by SANY Heavy Industry. The mixing systems utilize Model HZS180C8 automated concrete production units, each capable of producing approximately 180 m³/h, delivering combined production capacity of approximately 360 m³/h. The automated mixing arrangement incorporates intelligent metering systems, high-precision feeding controls, distributed network architecture, dual-machine dual-control arrangements, and advanced automated operational management capability designed to maximize offshore production reliability and continuous operational efficiency.
The mixing systems are engineered for continuous offshore production service and incorporate automated machine washing systems, intelligent unloading capability, multi-level door opening arrangements, high-precision ingredient feeding systems, and automated batching controls. The vessel’s fully enclosed production configuration significantly improves production consistency while minimizing environmental contamination, airborne dust emissions, and offshore operational waste discharge.
The vessel incorporates a highly sophisticated material storage and feeding arrangement engineered specifically for continuous offshore concrete production campaigns. Aggregate handling capability includes approximately 4 primary material storage stations with total aggregate storage capacity of approximately 5,000 Tons supporting long-duration offshore operational autonomy. Powder storage arrangements incorporate approximately 10 powder tanks configured as dual storage groups including cement tanks with combined capacity of approximately 600 Tons, fly ash storage tanks rated at approximately 300 Tons, mineral powder tanks rated at approximately 300 Tons, and additive tanks rated at approximately 100 Tons.
Material handling operations are arranged through integrated conveyor systems and digitally controlled weighing hoppers which transfer raw materials directly into the automated mixing units. External replenishment systems allow direct loading from dump trucks and land-based cement transport vehicles utilizing dedicated bottom-feed silo interfaces and elevated conveyor transfer arrangements. The replenishment arrangement is engineered to support efficient offshore logistics operations while minimizing material handling downtime during continuous offshore production campaigns.
Concrete transportation and offshore pouring operations are supported through integrated SANY Heavy Industry pump truck systems incorporating approximately 56 m distribution booms and conveying pumps rated at approximately 180 m³/h capacity. Pumping systems are capable of approximately 180 m³/h low-pressure discharge rates together with approximately 125 m³/h high-pressure discharge capability. Pumping pressure ratings reach approximately 8.3 MPa under low-pressure operation and approximately 12 MPa under high-pressure operation. Pumping cylinder arrangements incorporate approximately 260 mm internal diameter with approximately 2,100 mm cylinder stroke configuration supporting dependable high-volume offshore concrete transfer capability.
The vessel is specifically engineered with substantial environmental protection capability throughout all operational systems. Powder storage arrangements utilize pulse-type environmentally friendly dust extraction systems while aggregate storage areas incorporate pulse-type eco-friendly dust extraction systems together with automated water mist dust suppression arrangements. The vessel additionally incorporates intelligent zero-discharge wastewater and waste recycling systems utilizing centralized waste separators capable of achieving approximately 100% slurry recovery rate while eliminating operational discharge into the marine environment. The environmental management system is specifically engineered to support compliance with modern offshore environmental protection standards and marine construction regulations.
Positioning capability is provided through an integrated multi-anchor offshore station keeping arrangement incorporating approximately 8 anchor positioning configuration. The vessel is fitted with approximately 4 x 200 kN electric anchor winch systems positioned at vessel corners together with approximately 4 x 12 Ton heavy-duty anchors supporting stable offshore positioning capability during concrete production and offshore construction operations. Additional positioning support is provided through approximately 4 x 100 kN hydraulic winch systems together with stern-mounted 62 mm hydraulic anchor machinery and approximately 1 x 7 Ton Hall anchor arrangement.
Accommodation and operational support spaces are configured to support long-term offshore project deployment capability. Internal arrangements include approximately 27 single accommodation rooms together with dedicated meeting rooms, medical facilities, food storage rooms, restaurant facilities, kitchen arrangements, work monitoring rooms, and centralized mixing control rooms supporting continuous offshore operational management capability.
The overall vessel configuration is specifically engineered for offshore bridge construction projects, offshore wind farm developments, marine infrastructure support operations, offshore concrete placement campaigns, harbor construction, caisson fabrication support, dredging infrastructure projects, and large-scale offshore civil engineering operations requiring dependable offshore concrete production capability combined with modern environmental protection standards and automated production efficiency.
