Types of Offshore Crane
Offshore cranes can be categorized into various types according to their structure and usage, including ship cranes, floating cranes, mast cranes and so on.
Marine crane
Marine crane, mainly used for cargo transfer between ships, sea supply, underwater operation equipment placement and recovery. It has the advantages of high loading and unloading efficiency, easy operation, small occupation of deck area, etc. It is especially suitable for lifting and loading of heavy cargo. However, the self-importance, large volume and high center of gravity of marine cranes have a certain impact on the stability of the ship, and the ship’s power station and overhaul technology requirements are high, the price is also relatively high.
Floating crane
A floating crane is a commonly used offshore crane, consisting of one or more pontoons, which can be easily moved at sea. Its main advantage is its mobility, which makes it suitable for offshore construction, building, demolition and other tasks. In addition, the floating crane can be installed with different types of lifting equipment as needed, such as cradles, bucket cranes, lifting hooks, etc., which makes it highly applicable. However, its stability may be affected by the offshore environment.
Mast crane
A mast crane is a kind of lifting equipment based on the mast, which is mainly characterized by a simple structure, easy to use and suitable for simple lifting operations. It is usually installed on small vessels with small lifting weight limitations and a relatively narrow scope of application. In addition, offshore cranes can also be divided into electric cranes and hydraulically driven cranes according to the driving method. Electric cranes have the advantages of high efficiency, correct speed, easy operation, less maintenance and easy remote control. Hydraulically driven cranes are characterized by stable operation, light quality, small size, step-less speed regulation, constant power, high speed with empty hooks and slow speed with light loads.
Use Cases of Offshore Cranes
Offshore oil and gas industry
They play a crucial role in the oil and gas industry, facilitating lifting operations for drilling equipment, subsea installations, and maintenance tasks. They ensure the smooth functioning of offshore platforms and maximize productivity.
Offshore wind farms
These cranes are vital for the installation, maintenance, and repair of wind turbines in offshore wind farms. They enable the safe and efficient transportation of heavy components, contributing to the growth of renewable energy sources.
Subsea construction
They are utilized in subsea construction projects, including the installation of pipelines, subsea structures, and underwater equipment. They provide the necessary lifting capacity and precision for these critical operations.
Structure and Composition of Offshore Cranes
Offshore cranes are usually composed of the following parts:
Lifting boom
This is the main working part of the crane, usually made of high-strength steel, capable of withstanding huge lifting loads. The length and strength of the boom determine the lifting range and capacity of the crane.
01
Turntable and slewing mechanism
The turntable is the center part of the crane, supporting the lifting arm and allowing it to rotate horizontally. The slewing mechanism is driven by a motor or hydraulic pressure to realize the all-around rotation of the lifting arm.
02
Hoisting mechanism
This is the system that controls the wire rope winch, which is driven by an electric motor or a hydraulic motor to wind or loosen the wire rope, thus realizing the lifting and lowering of the heavy load.
03
Traveling mechanism
For cranes installed on ships or floating platforms, the traveling mechanism allows the crane to move on the platform to adapt to different working positions.
04
Control system
Includes an electrical control system and hydraulic control system, which is used to control the movements of the crane to ensure its precise and stable operation.
05
The Difference Between Marine Cranes and Offshore Cranes
Marine cranes, also known as deck cranes, marine cranes have two types , electric and hydraulic type. The scope of application of marine cranes is wider.
Marine crane, we usually install it on the ship for loading and unloading cargo and containers in ports and sheltered, stable waters. Under such environmental conditions, the wind is not greater than Beaufort scales level 2, and the sea state is not greater than level 2. Only in this way can the normal and safe loading and lifting of goods be guaranteed.
One most difference between offshore cranes and marine cranes is the working environment/condition(sea state). Offshore cranes are often used in open waters offshore. Compared with marine cranes, they can adapt to more complicated sea conditions. Of course, the requirements are higher, and it is suitable for sea conditions with a heel greater than 5° and a trim greater than 2°. It can be used for marine cargo ships, offshore drilling platforms, and supplementary living materials, equipment and materials.
Therefore, the difference between marine cranes and offshore cranes is obvious, and customers need to choose the appropriate crane type according to different working condition.
Understanding Offshore Crane Operations
Offshore cranes are specialized lifting devices used extensively in marine environments, particularly on ships, platforms, and oil rigs. These cranes are designed to operate in the rough conditions of the sea, including strong winds, waves, and corrosive saltwater. Their primary function is to handle the heavy lifting and maneuvering of loads that are crucial to the construction, maintenance, and operation of offshore facilities. Built to withstand the harsh maritime environment, these cranes are essential for ensuring the smooth operation of various offshore activities.
Offshore cranes are used to lift and move heavy machinery and equipment. These operations require cranes that can handle significant weights with precision and safety. In the construction of offshore platforms, cranes play a vital role in assembling structures. They lift and position large components, ensuring that construction projects are efficient and safe.
Regular maintenance of offshore installations is crucial for their continued operation. Offshore cranes lift heavy parts for repair, replace worn-out parts, and perform routine maintenance tasks. These applications highlight the versatility of offshore cranes in the marine industry. Their ability to perform heavy lifting and precise handling under challenging conditions makes them a cornerstone of offshore operations.
Offshore crane is a kind of crane specially designed to operate in offshore environments. For loading and unloading cargo and materials in port and offshore conditions. Most of them are custom-made products because they are designed to work in the sea environment, which is more complex to use, so if you want to buy an offshore crane, what information do you need to provide to the marine crane manufacturer to customize it?
First of all, you need to provide the (SWL) safe working load of the marine and offshore crane, SWL means the capacity of the load and the radius relative to the crane, for example, a set of 3T40M crane, then 3T40M is its SWL, meaning the working radius is 40 meters and can lift 3T. Of course, taking into account the self-weight of the hook, the material structure of the boom and safety factors, we generally do not suggest to lift the weight of more than 3T, which is one of the necessary parameters you need to provide to purchase a crane.
Secondly, you also need to inform the offshore crane manufacturer about the type of crane boom, You can choose telescopic boom, stiff boom, knuckle boom or foldable knuckle boom, etc. This requires the user to decide according to future use, ship size and deck space!
The environment for working at sea will be more complicated. Therefore, It would be better to provide Beaufort level, sea state and wave factor of the sea area where the crane is used. According to the specific conditions of working environments, the manufacturer can determine the appropriate Design.
In addition, the height of the marine crane from the water, the power unit system, the crane self-weight requirements and the temperature of the application environment, all the above parameters are important. The more information you provide, the better the supplier will be able to meet your expectations. Then, provide you with a suitable design and precise quote. After order confirmed, the manufacturer can also complete the customization of products according to the specific situation.
The cranes used in lifting activities on offshore platforms, whether fixed or floating, are generally of the “crane on pedestal” or “pedestal crane” type, where the superstructure is fixed on a steel tube welded to the hull or to the surface. platform structure.
This geometry differentiates the offshore crane from the land crane in terms of overturning stability, ensuring greater robustness to the former and obviously freeing it from problems of support base repression, as can happen with land cranes.
When loading tables, there are very important differences, the main addition being the parameter of significant wave height (Hs), which is the average of the one third of the highest wave heights in a period of time, and is used to estimate the load. maximum lifting force that can occur during an operation due to the movement of the platform, the crane, the support vessel and the load. The higher the wave height, or Hs, the more force the crane must withstand, lowering its maximum working load.
As for operational risks, offshore cranes are susceptible to overload due to the hook being caught in the support boat and, when it descends on the wave, it can even pull the superstructure off the pedestal. To reduce this risk, electronic overload suppression devices can be used (European approach) or increased structural robustness (American approach).
Another operational difference is that offshore cranes, at least the most modern ones, are certified to lift people for transshipment, which is not allowed by land crane manufacturers, including mandatory safety devices.
