||Something https://www.omc-stepperonline.com that picks, orients and places a fond memory is common in machines automation. However, when it's a part of a wind-farm installation positioned offshore, it's a rather complex and impressive home gym (Figure 1).
Our business, Houlder, was tasked to produce a reliable, fast and safe and sound system to lift huge wind-turbine steel-foundation monopiles. Each monopile, a cylindrical metal tube support structure, weighs 855 tons and need to be lifted from a horizontal position around the deck of the installation vessel into a vertical orientation at the particular target installation position throughout preparation for pile-driving it in the seabed.
Our solution recommended designing a wirelessly controlled crane attachment [url=https://www.omc-stepperonline.com/nema-23-stepper-motor/]https://www.omc-stepperonline.com/nema-23-stepper-motor/[/url] using Nationwide Instruments' CompactRIO and LabView. The actual crane attachment automatically engages a monopile, upends it, safely suspends it and allows precisely position it. Once the pile is in position and restrained, the attachment is remotely disconnected with the monopile and parks to recharge the facility units. Using CompactRIO and LabView for that pile-upending tool allowed all of us to rapidly and cost effectively produce a control system that we are able to easily update and boost for use on potential wind-farm projects.
Houlder's marine equipment business is found in Tyne and Have on, England. The company is definitely an independent, employee-owned provider involving design and engineering providers, [url=https://www.omc-stepperonline.com/]https://www.omc-stepperonline.com/ omc-stepperonline[/url] as well as equipment used in many marine markets including just offshore renewables, oil and energy, defense and liquefied propane. The company delivers turnkey methods of engineering challenges in all these sectors. Our engineers, naval designers, designers and project managers do a lot more than offer their expertise towards the market. They combine forces to bring clarity to help industry challenges and current well-considered solutions. They steadiness their intellect, experience plus practical knowledge.
The offshore wind village project required two logpile upending tools for operation onboard the heavy-lift jack-up installation vessels MPI Discovery and Swire Blue Ocean Pacific Orca. The tool lifts monopiles which will be [url=https://www.omc-stepperonline.com/]check my blog[/url] driven into the particular seabed to act as the foundation for wind turbine generators.
We won the project due to with the multitude of our experience, innovation inside the sector, project success amount and reliability.
Our objective was to enhance pile upending operations having a heavy lift crane. We identified numerous engineering challenges to beat, including:
controlling the upending software pivoting and locking cylinders
powering wireless remote communication among operator and upending instrument
monitoring of upending software parameters
overcoming major safety implications we've passed away of upending tool inability
delivering an upending software control system in compliance with both DNV GL principle 2. 2, 'Lifting devices, ' and EN ISO [url=https://www.omc-stepperonline.com/stepper-motor-driver/]indications of stepper motor driver[/url] 13849-2, 'Safety of machinery'Safety-related areas of control systems. '
Addressing these issues would end in a faster, more cost-effective, safer plus more reliable monopile installation method.
The upending applications comprise many parts, including a crane attachment, flange connect, control cabinet, batteries, hydraulic accumulators, hydraulic reservoir, hydraulic pump, rotating cylinder and locking cylinder.
We developed an upending tool that's self-powered during operations utilizing absorbent-glass-mat (AGM) batteries with the control system and hydraulic accumulators as well as a charging pump to provide hydraulic power to the upending tool actuators.
The actual tool includes two hydraulic actuators: a pivot cylinder along with a locking cylinder. The pivot cylinder provides rotation with [url=https://www.omc-stepperonline.com/stepper-motor-driver/]stepper motor driver[/url] the tool and locking instrument. This allows it to engage the horizontally positioned monopile located on the vessel deck. The locking cylinder buttons mechanically to two locking latches utilized to lock the upending tool in position on the monopile top flange.
Once the upending tool engages as well as being locked to the monopile upper flange, the upending treatment continues. During pile upending, the pivot cylinder should go into float mode and so the tool can pivot freely since the pile is lifted via horizontal to vertical. One time the pile is up and down, it is moved towards the installation position using a crane where it can be restrained using.
