History of the hang-off

More than a decade of Hang-Off experience

Over the past years, Vos Prodect has been established as a market leader in the engineering and supply of cable hang-off systems by continuously reinventing itself in the face of shifting market demands and industry trends. In 2011, the first edition of the Vos Prodect Cable Hang-Off System was already introduced to the world. Within the industry, Vos Prodect has gained over the years a reputation of quality and has been trusted with over 250 successfully completed projects, supplying the Vos Prodect systems across the globe.

In general, a cable hang-off system is designed for securing medium and high voltage power cables to the top of a foundation/cable deck in a monopile, oil rig, oil platform or jacket. The cables are threaded through using an entry system into the monopole and secured at the cable deck with a Hang-Off System. The hang-off system has to be airtight, as toxic gases are formed due to cathodic corrosion protection of the monopile and pose a health and safety risk to potential work crews on the cable decks.

When developing a Hang-Off System, it has to conform and adhere to many operational requirements for offshore wind farm projects. That is the reason why Vos Prodect continuously works on new generations of the cable hang-off system. Below we will share our journey into our hang-off system evolution.

Vos Prodect Hang-Off System 1.0

Developed in 2011, the original Vos Prodect HOS 1.0 was developed using a spherical shaped body which was easy and simple to install. The casted iron 1 piece hang-off system was able to fit most cable diameters using a combination of the temporary clamps, along with the final hang-off clamp to secure. However, as time moved on, the sizes of the cable diameters began to vary increasingly which effected the housing body, this lead to Vos Prodect innovating the 2nd generation hang-off system.

Vos prodect Hang-Off System 2.0

Developed in 2015, the Vos Prodect HOS 2.0 introduced a newly designed housing body to fit all possible cable diameters. Along with the new design of the cylindrical housing chamber, Vos Prodect also began to develop a variety of temporary clamps in Small, Medium, Large and Extra Large sizes, to adapt to varying diameters of the cables. However the frame of this hang-off system was formed of a welded body, which during manufacture could become time consuming, due to ensuring these frames were airtight to the project design. Due to the extra attention required for this, the welded body potentially became a less cost effective solution.

Vos prodect Hang-Off System 2.1

Developed in 2017, the Vos Prodect HOS 2.1 reverted back to the casted iron frame with the vision to develop a cost effective, easy to fit, bolt on system for our customers. The redesigned 2.1 generation hang-off system is quick and simple to install, in a variety of off the shelf sizes to ensure a fast turnaround on the entire system components. Vos Prodect have acquired the moulds for each of our developed components to ensure that our hang-off system is ready for your project design. In a variety of readily available sizes to suit all cable diameters within the industry, the Vos Prodect HOS 2.1 provides a high quality and effective hang-off system. The Vos Prodect HOS 2.1 has been tested extensively over the years to ensure the integrity and quality is up to the highest possible standard within the industry.

Our history of our hang-off system innovations demonstrates the determination of our vision to learn and adapt to the market changes. At Vos Prodect we want to ensure that we are engineering a high quality and tested system and that our innovations are formed to provide our customers with cost effective solutions.
