Oil Tankers

Width: Approximately 60 meters
Depth: about 30 meters
Structural draft: approximately 22.5 meters
Speed: 14.5-15.8 knots
Propulsion method: single propeller propulsion; Modern VLCCs are widely equipped with MAN B&W or WinGD low-speed two-stroke dual fuel engines
Main engine power: The main engine power of large oil tankers can reach 22.5 MW or more
Range: Approximately 20000-2500 nautical miles
The new generation of oil tankers significantly improves propulsion efficiency by optimizing their line shape, configuring efficient propellers, and energy-saving devices.
🌱 Environmental Protection and Safety Configuration
Modern oil tankers fully implement the concept of green and environmentally friendly design:
Double shell structure: The cargo oil tank area is enclosed by a double bottom, double shell, isolated empty compartment, and deck, effectively reducing the risk of accident pollution
Emission control: Equipped with SCR system, nitrogen oxide emissions meet NOx Tier III standards
Carbon emissions: Energy Efficiency Design Index (EEDI) meets Phase III requirements
Dual fuel power: LNG dual fuel, methanol reserve, ammonia fuel reserve have become mainstream directions
Compliant with specifications: Meets the latest Common Structural Code (CSR) of the International Association of Classification Societies (IACS)
🧊 Cargo hold and structural configuration
Double hull oil tanker: The cargo oil tank area is enclosed by a double bottom, double hull, isolated empty compartment, and deck. It is prohibited to load cargo oil or fuel oil inside the double bottom and double hull
Cargo oil tank layout: compartments are separated by longitudinal bulkheads, and the height of the double bottom increases with the width of the ship. For medium-sized ships, it is about 2-2.5 meters, and for large ships, it can reach up to 3 meters
Number of cabins: Taking VLCC as an example, cargo oil tanks are usually arranged in five rows, totaling 17 cabins
Unloading equipment: using steam driven turbine centrifugal cargo oil pump, the theoretical unloading rate of a single pump is about 5500 cubic meters per hour
The configuration of oil tankers is a comprehensive reflection of ship engineering, safety technology, and environmental standards. As the global shipping industry transitions towards green and low-carbon, the new generation of oil tankers is continuously evolving towards a more environmentally friendly, intelligent, and efficient direction.
