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.
Обзор
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.
