ICSA Guidance for Land-Based Cranes Working on Vessels
Using land-based mobile cranes on barges or vessels introduces significant challenges related to stability, motion, load-handling and environmental conditions. Cranes for You includes this ICSA guidance because safe crane operations on floating or semi-floating platforms are critical for achieving Goal Zero in lifting, hoisting and specialised maritime transport operations.
Summary of the Vessel-Based Crane Guidance
- Motion and dynamic effects — Understanding vessel movement, swell, acceleration and roll, and how they influence crane stability and load control.
- Ground conditions on deck — Requirements for deck strength, load-spreading, mats, grillage and structural verification before crane setup.
- Positioning and securing the crane — Guidelines on lashing, securing systems, anti-slide measures and maintaining stability during transit or lifting.
- Environmental limits — Wind, tide, current and wave-height thresholds for safe crane operation on a floating platform.
- Operational planning & communication — Aligning crane teams and marine crews, establishing clear radio protocols, and defining responsibilities.
Practical Relevance for Marine and Offshore Projects
Applying this guidance helps teams:
- safely use mobile cranes on barges, pontoons and support vessels;
- prevent crane instability caused by vessel movement or insufficient deck support;
- establish unified procedures between crane crews and marine operators;
- conduct accurate lift planning in tidal, coastal or nearshore environments;
- reduce project delays and incidents during offshore construction or load-out operations.
