Guidance for working with cranes on floating vessels

This page is an introduction to working with cranes on barges. Find out about different configurations and how to plan a lift.

Land-based mobile cranes are sometimes used on on floating vessels such as barges and pontoons. This type of use has unique hazards. Extra considerations are needed before starting operations to make sure the crane and vessel are used as intended. It is recommended to get approval from the manufacturer or a qualified person for this type of work.

Crane and vessel configurations

Different types of vessels can be used to support crane operations. Each application should be reviewed independently for any special considerations, additional planning or risk mitigation.

There are many crane and vessel types that can be used in different combinations. The following factors should be considered when using this guide:

• size of the crane
• crane configuration
• loads to be handled in relation to the size of the vessel
• sensitivity of the crane configuration to vessel movements when using longer boom systems with luffing jib and/or suspended counterweight
• how the ‘crane and vessel combination’ will respond to load displacement and outside environmental influences (such as wind and water movement)
• the impact of stored materials, ancillary and fixed plant and equipment on list and trim values during operations

This section of the guide does not cover the operation of land-based mobile cranes in the following situations:

• on offshore vessels (also known as sea-going vessels)
• on vessels in unprotected areas with waves
• on jack up vessels or other non- floating vessels
• load ratings when used on vessels

Manufacturer and local or government regulations should be followed.

The information about cranes on barges in the Dogging and Rigging Guide has been developed by International Crane Stakeholder Assembly (ICSA).

Planning

Proper planning will help avoid risks that may affect the crane and/or vessel. Dangerous situations could result from:

• excessive listing of the vessel
• shifting of the load and/or crane
• vessel movement
• material storage
• vessel layout.

A lift planning flowchart (PDF 164.53KB) should be adopted as part of a pre-planning activity.
