This project, located in the Taiwan Strait, will have a power generation capacity of 2.4 GW capable of supplying green energy to approximately one million Taiwanese households.
To install the 33 steel jackets, each weighing approximately 2,500 tons, Sarens has selected a wide range of cranes, including the SGC-90, also known as “Little Celeste”, an electric crane that can lift up to 1,650 tons.
The project will boost employment generation, not only through the operation of the plant but also for suppliers like PetroVietnam Technical Services Corporation (PTSC), as the construction of the jackets will require 70,000 tons of steel.
The Greater Changhua offshore wind farm will produce clean energy equivalent to the reduction of 830,000 tons of CO2 emissions. Located in the Taiwan Strait, this complex, which will be the largest in the country, has a planned total capacity of 2.4GW that will be able to supply clean energy for approximately one million Taiwanese households.
The project, operated by Ørsted, will also provide a major boost to the economy by generating employment, not only through the creation of jobs during construction, but also through the overall supply chain. For example, an estimated 70,000 tons of steel will be used to manufacture the foundations alone, creating thousands of jobs at PTSC and other contractors in the supply chain.
Sarens, world leader in heavy lifting, engineered transport and crane rental services, has been an active part of the project on behalf of its client PTSC, with which the company signed a Memorandum of Understanding after 12 years of close collaboration, jointly developing projects such as Bien Dong 1, Te Giac Trang H5 or Ghana OTCP FPSO, Gallaf Batch 1 LQUP.
In the Greater Changhua project Sarens is carrying out the assembly and integration of 33 steel jackets for offshore turbines, with an estimated weight of 2,500 to 2,800 tons each. To carry out this task, Sarens' team of experts selected a wide range of cranes such as the Liebherr LR1750, which has a lifting capacity of up to 750 tons, or the Demag CC2800-1, a crawler crane with a lifting capacity of 600 tons, which are part of Sarens Vietnam' local equipment. In addition, a CC6800 from Thailand has been used, capable of lifting up to 1250 tons, with a maximum boom extension of 150 meters.
The main integration crane on the job is the SGC-90, also known as Little Celeste. This ring crane is the first in the world to be able to fully operate on electricity, without the need to consume fossil fuels, and is therefore very quiet in operation. It has a maximum lifting capacity of 1,650 tons and a maximum load moment of 99,000 Tm.
The project will have to be completed in a tight time frame, so the SGC 90 crane had to be brought in from France and the CC6800 from Thailand to ensure the availability of all the necessary machinery for the operation without incurring in delays.
Thanks to having all the equipment available months in advance for planning, the entire operation for the erection of the 33 jackets took only 1 year, including setup and installation. The job site was the PTSC yard, where all the large-capacity cranes had enough space to be able to operate perfectly without any delays during assembly. Lifting was done in tandem, with both crane operators carefully complying with Sarens' strict safety standards.
Sarens has extensive international experience in the assembly and maintenance of wind farms. It has participated in various installations in France such as Fécamp, Saint Nazaire, Provence Grand Large in the lifting and transport work for the foundation bases of the new offshore wind farm in Saint Brieuc, located off the Brittany coast. During this project, Sarens successfully transported loads weighing over 1,150 tons. More recently, Sarens has worked in the receiving and loading out the monopiles and transition pieces for 176 turbines for the Coastal Virginia Offshore Wind Farm.
