This project involved the construction and delivery of a series of three Product Oil Tankers for a major Chinese shipping company.

Designed for bunker supply operations and petroleum product transportation within Singapore and Southeast Asian coastal waters, the vessels provide an efficient and reliable solution for regional fuel logistics.

Built in accordance with CCS Classification Rules, IMO Conventions, and Singapore maritime regulations, the vessels combine proven tanker design, operational flexibility, and robust construction standards, making them a valuable asset for coastal oil transportation.

Principal Particulars

Classification & Compliance

The vessels were designed and constructed in compliance with:

· China Classification Society (CCS) Rules

· IMO Conventions

· Singapore Maritime Regulations

· International Marine Pollution Prevention Requirements

The vessels are capable of transporting various petroleum products with flash points above 60°C and support flexible loading and discharge operations for multiple cargo grades.

Design Highlights

Proven Double Hull Safety Concept

The vessels feature a full double hull and double bottom configuration, providing enhanced environmental protection, structural strength, and operational safety.

This proven tanker arrangement significantly reduces pollution risks while ensuring long-term structural reliability.

Flexible Cargo Operations

The cargo system is designed to support efficient handling of multiple petroleum products, enabling operators to maximize utilization across a variety of fuel transportation and bunkering applications.

Optimized Coastal Trading Performance

The vessels are specifically tailored for short-sea and coastal operations, offering an effective balance between cargo capacity, fuel efficiency, and operational flexibility.

Machinery & Equipment

Reliable Propulsion System

Each vessel is powered by:

· 2 × Cummins KTA38-M0 Medium-Speed Marine Diesel Engines

· 2 × HCT800 Marine Reduction Gearboxes

The propulsion arrangement delivers dependable performance, fuel efficiency, and low maintenance requirements for intensive operational schedules.

Power Generation System

The electrical plant includes:

· 2 Main Generator Sets

· 1 Emergency Generator Set

ensuring continuous and reliable power supply for vessel operations and cargo handling activities.

Integrated Marine Systems

The vessels are equipped with:

· Cargo Pumps

· Ballast Pumps

· Firefighting Systems

· Radar

· GPS

· AIS

· Satellite Communication Systems

· Environmental Protection Equipment

All systems comply with applicable safety and environmental regulations.

Construction Quality

Robust Hull Construction

The hull structure was fabricated using certified marine-grade steel with reinforced framing arrangements in cargo tank and deck areas.

Critical structural welds were completed using automated welding processes and subjected to comprehensive non-destructive testing (NDT) to ensure structural integrity and long-term durability.

Advanced Coating Protection

A comprehensive coating system was applied throughout the vessel, with specialized coatings selected according to the operational requirements of each area.

The coating scheme provides excellent resistance against corrosion, saltwater exposure, and tropical marine environments, significantly extending service life and reducing maintenance costs.

Professional Outfitting Standards

Piping systems, valves, firefighting equipment, navigation instruments, and communication systems were installed according to detailed engineering standards, ensuring safe operation, easy maintenance, and clear system identification throughout the vessel.

Series Construction Capability

All three vessels were built using:

· Unified Engineering Drawings

· Standardized Production Procedures

· Consistent Quality Control Systems

This approach enabled efficient project execution while maintaining identical construction quality across the entire fleet.

Throughout construction, resident classification surveyors conducted continuous inspections covering:

· Material Certification

· Hull Fabrication

· Welding Quality

· Equipment Installation

· Harbour Trials

· Sea Trials

More than one hundred technical inspection items were successfully completed and approved.

Delivery Performance

The three vessels were delivered in accordance with the agreed project schedule and successfully passed owner acceptance inspections and classification surveys.

Each vessel was handed over with a complete documentation package including:

· Statutory Certificates

· Classification Documentation

· Equipment Manuals

· Spare Parts Inventory

· Operational Records

Project Outcome
