Project Overview
This project involved the construction of a series of ten (10) 700 DWT Double Hull Lubricating Oil Tankers for a leading Singapore-based oil company.
The vessels were specifically designed for bunker supply and petroleum transfer operations within Singapore port limits and nearby coastal waters. The design complies with Singapore maritime regulations, applicable IMO requirements, and China Classification Society (CCS) rules.
To further enhance construction quality and regulatory compliance, the final two vessels of the series were built under joint supervision by CCS and ABS surveyors.
The successful completion of this project demonstrates our capability in delivering high-quality tanker fleets for international clients through standardized series production and comprehensive project management.

Design Highlights
Optimized Tanker Design
The vessels feature a full double hull and double bottom arrangement, providing enhanced environmental protection, structural integrity, and operational safety.
The cargo tank region adopts a longitudinal framing system designed to improve hull strength while maintaining efficient cargo operations.
Advanced 3D Engineering
Comprehensive 3D modeling was utilized throughout the design phase to optimize machinery arrangement, piping systems, and equipment integration.
This approach minimized installation conflicts and improved construction efficiency and maintainability.
High-Performance Protective Coating System
Cargo and ballast tank coatings were applied using internationally recognized marine coating systems in accordance with PSPC requirements, ensuring long-term corrosion protection and reduced maintenance costs.
Equipment Integration
Integrated Bridge Control System
The wheelhouse is equipped with an integrated vessel management platform, providing centralized control and monitoring of:
· Main propulsion systems
· Steering systems
· Cargo and service pumps
· Alarm and monitoring systems
Modern Navigation & Communication Suite
The vessels are fitted with a complete navigation and communication package including:
· Radar
· AIS
· GPS
· GMDSS-compliant equipment
The arrangement fully satisfies operational requirements for Singapore waters.
Reliable Equipment Selection
Major machinery, pumps, switchboards, and auxiliary systems were sourced from established marine equipment manufacturers to ensure operational reliability and low lifecycle maintenance costs.
Construction & Project Execution
Standardized Series Production
All ten vessels were constructed using unified engineering drawings, standardized production procedures, and consistent quality control systems.
This approach ensured:
· Consistent vessel quality
· Efficient production scheduling
· Improved cost control
· Reliable delivery performance
Quality Assurance
Construction was carried out under strict inspection and testing procedures, including:
· Material Verification
· Welding Inspection
· Non-Destructive Testing (NDT)
· Tank Tightness Testing
· Equipment Commissioning
· Sea Trials
Client Witnessing & Acceptance
Our project team worked closely with the owner's representatives throughout construction, commissioning, and sea trials, providing full technical support and ensuring all contractual performance requirements were achieved.
Delivery Performance
The complete fleet was successfully delivered in phases according to the project schedule.
All vessels passed owner and classification acceptance inspections and entered commercial service with comprehensive documentation packages, including:
· Statutory Certificates
· Classification Certificates
· Equipment Manuals
· Operational Documentation
Project Outcome
· This project represents one of our benchmark international tanker construction programs.
· Through customized engineering, strict quality management, and mature series-production capability, we successfully delivered ten identical vessels that continue to serve as reliable bunker supply units within Singapore's maritime industry.
· The project further strengthened our reputation as a trusted shipbuilding partner for international oil and marine transportation companies.
