Heavy-Lift Vessels for Extreme Cargo
Heavy-lift vessels are specialized ships with cranes exceeding 400 tons capacity, designed to transport extremely heavy and oversized cargo that standard vessels cannot handle.
Overview
Heavy-lift vessels represent the pinnacle of cargo ship engineering, featuring cranes from 400 to over 3,000 tons capacity in single or tandem lifts. These vessels are essential for transporting transformers, offshore modules, complete industrial units, and other ultra-heavy items. Major operators include BigLift, SAL Heavy Lift, and Jumbo Shipping. These vessels often feature reinforced decks, sophisticated ballast systems for trim adjustment, and motion compensation technology.

Loading & Handling Tips
Frequently Asked Questions
When do I need a heavy-lift vessel?
Heavy-lift vessels are typically required for single pieces over 200 tons, items with lift heights over standard crane reach, or when ports lack adequate shore cranes. Your cargo dimensions and weight will determine the requirement.
How far in advance should I book a heavy-lift vessel?
Book 2-6 months in advance for standard routes. For complex projects or peak seasons, 6-12 months lead time is recommended. Spot availability is rare for these specialized vessels.
Can heavy-lift vessels deliver to offshore locations?
Yes, many heavy-lift vessels have dynamic positioning (DP) systems allowing them to hold station offshore for module delivery to platforms, FPSOs, or installations at sea.
