Equipment exceeding the capacity of the shore crane is usually lifted using floating craneįigure 1: Offshore lifting Examples of offshore lifting Shore crane with limited lifting capacity: Generally shore crane lifting capacity is only up to 200 tonnes.Sometimes, when a vessel is berthed port side, but it’s required to lift up or install equipment in starboard side, which cannot be reached by the shore crane When shore crane cannot perform the lifting.During offshore installation, i.e., Installing any process module, structure at the operation site.In this article, we will discuss offshore lifting operations and associated engineering analysis, safety precautionary measures, contingency plans, and challenges involved in lifting. “This flexibility is important because 3D Lift Plan is a cloud-based program, eliminating the need to download and update software to individual computers.” When using one of these browsers, users need to select the WebGL version.Offshore lifting is a common operation in offshore construction or installation projects at sea. “We have also utilised WebGL technologies to enable the display of 3D content in Chrome, Firefox, and Microsoft Edge web browsers to improve the interface for customers no matter their preferred browser,” added Tawnia Weiss, president of A1A Software. When this configuration is selected, 3D Lift Plan will calculate the sling angles and tension, A1A Software claimed. The new configuration has two spreader bars and four roll-blocks.

For example, users can now: override the boom angle when using a load chart with fixed boom angles establish one crane in setup mode while simultaneously putting other cranes in normal operation mode for the creation of erection and dismantling plans and knife-jack a lattice boom with luffer to verify procedures for lowering long lattice/luffer combos into stowed position.Ī new rigging configuration has also been added to the standard options in the Advanced Rigging Design portion of the program. Other improvements, said A1A Software, offer users greater control of planning for unique lifting scenarios. Printouts of the crane mats in the lift plan now display corresponding images of steel mats instead of wood when steel mats are selected as part of the plan. This is in addition to the previous ability to select wood mats or DICA’s SafetyTech or FiberMax engineered outrigger pads or crane pads. Ground bearing calculations can now be made for steel mats with an option for layering steel mats over timber for better distribution of outrigger loads. It is now possible in 3D Lift Plan to knife-jack a lattice boom with luffer to verify procedures for lowering long lattice/luffer combos into stowed positionĪ1A Software said users can now use the program to determine which type of crane pads or mats are best for the ground conditions.
