Upending Hinge
Our upending solutions facilitate a controlled, stable and safe operation. With 15 years of experience, TWD delivers customized solutions for every pile or object that needs to be up or down ended, whether it’s on a heavy lift vessel, jack-up, barge, or on land.
Our expertise ensures that we tailor functional solutions to meet the specific requirements of your project. Considering offshore dynamics, we ensure that the operation is conducted within the required workability limits and timeframe. These unique upending designs have contributed to the successful installation of many piles, such as pin piles for jackets, or monopiles.

Adjustability for Pile Diameters
Within each project, monopiles and pin piles are optimized to suit the installation site conditions, resulting in variations in pile lengths and diameters. TWD has designed many customized upending mechanisms capable of accommodating various pile diameters, reaching up to 12.5 meters. These mechanisms range from project specific and cost-effective filler blocks to future proof and rapidly operated remote-controlled jacking systems.
Adjustability for Pile Lengths
In addition to the differing diameters, the lengths of the piles can also vary significantly. For instance, when a heavy lift vessel is installing long piles, this presents challenges regarding the crane capacity and height during the initial stages of the upending operation. For such a case, a long stick-out of the upending hinge can be an effective solution to bring the top of the pile closer to the crane. Additionally, to facilitate the installation of smaller piles, the upending hinge bottom beam can be made telescopic.
Challenges of The Dynamic Environment
Ensuring a safe upending operation offshore, with optimal workability, requires a good understanding of environmental loads and vessel behavior. This is especially important for floating installation vessels, where piles are upended through the splash zone amidst the vessel motions. Leveraging calculations and simulations, we have developed an expert understanding of these operations,. enabling our clients with the offshore workability limitations they require.
Tailored Solutions
Project specific requirements lead to variation in installation methods and assets. TWD’s extensive track record in upending designs includes solutions for autonomous and craneless upending of piles. Additionally, we designed upending hinges with lowering mechanisms, enabling the skidding the piles from seafastening position into the upend line. These are just a few examples of tailored functionalities that we offer.
