A floating crane, also known as a crane ship or crane vessel, is a ship with a crane on-board that specializes in lifting and transporting heavy loads. They are mainly used for offshore construction, and are ideal for harbor work or on waterways with limited quay facilities. Floating cranes have been around since the 14th century, but the modern version of the floating crane appeared in 1920 on the battleship USS Kearsarge.
Huisman is one of the leading manufacturers of floating cranes. Husiman projects are innovative and complex, and over time they have built a strong reputation in the crane market. Terex is another popular manufacturer. They have several different models, including the Model 8, which is the most powerful floating crane on the market. It has a lifting capacity of up to 200 tonnes, and can work as not just a portable harbor crane, but also as a harbor crane on rails.
To become a floating crane operator, you first need to finish secondary school, and then enrol in a training program which typically takes between six and twelve weeks to complete. You will most likely be required to have a CPCS licence, and you will need to complete your NVQ. You may also be required to take speciality training to learn how to operate a floating crane specifically. You may also need to take a course on water and ship safety and procedures, because you will be working on a boat and potentially out at sea, depending on where the construction site is located.
Safety Features & Guidelines
Like all cranes, there are several important safety guidelines to follow before you begin working. Make sure you check all the buttons to ensure that they are working properly. Also make sure that the crane’s hooks, wire, and other features are all in working order. It is of vital importance to replace anything that looks worn out or damaged, as this can be a serious safety risk. When operating the crane, make sure you have clear communication with the operator on the ground. They will tell you where to put the load and warn you of any obstacles that you may not be able to see from your location. Because you may be working on a boat, it is also important to follow several water and boat safety guidelines as well. This includes learning to handle ropes properly, communicate constantly, and be vigilant and aware while on deck.
Pros & Cons
There are several advantages to using a floating crane, especially when working on a barge. For starters, they save money.
It can be costly to get a construction crew to bring out a tower crane or mobile crane, and even still there is no guarantee that these cranes will have the same effect as a floating crane would, because it may not be able to extend far enough to access the specific load. Floating cranes can serve multiple vessels at port, and you don’t need quay facilities for direct transhipment between seagoing barge and ship. Floating cranes can also supplement land-based handling capacities when additional capacity is required.
