FAQ

A

It’s a totally new paradigm. The main problem with marine oil spills is that when a spill begins, there’s nothing on site to keep it from spreading and splitting. Regular booms usually arrive hours after the spill has begun. At that point, the disastrous consequences are unavoidable. The minimal size and weight of T-Fence make it the only real containment boom that can be pre-installed wherever a spill might occur.

A

Yes it is! HARBO’s T-Fence is a blocking and containment solution, not a boom that is used for cleaning up spills by towing it to reconcentrate the oil that has already spread.The T-Fence is deployed around the spill before it spreads until it’s fully contained. This way the oil is kept together and does not cover large areas or split into small droplets. This is possible because the T-Fence is the worlds’ smallest and lightest oil spill solution. It can be stored at any potential point of failure and deployed immediately by non-professionals from small lifeboat-sized vessels.

A

In most cases, the regular boom will cost more in the long run, since it requires larger crews, peripheral equipment like forklifts, generators, pumps, a lot of storage space and two vessels. The total cost of ownership is higher. When a boom is covered in oil, cleaning it is both hazardous and expensive and can increase pollution. In some cases, booms are sent directly to landfills because it makes more sense to dispose of them than to clean them. Most importantly, given the attributes of HARBO’s disposable boom, the total costs of a spill will be significantly lower.

A

By making the boom disposable, HARBO can make it highly compact and effective, thereby enabling its core benefits. Also, in many places – contaminated booms are disposed of anyway. De-contaminating a boom is a hazardous and costly process, unhealthy for the environment and especially challenging in remote locations. With HARBO’s boom, disposal costs are significantly lower: it’s made from plastic alone. It can be burned (incinerated) and in general, requires a significantly smaller volume to be handled. HARBO will offer special solutions for training.

A

The main use of regular booms is to “mop up” the water to concentrate a sufficient amount of oil before skimming. They are bulky and heavy, so it takes hours to get organized before getting to the spill, and they are much harder to handle during the spill itself. HARBO’s systems are located at standby positions at the point of failure so that they can block the spread of oil right from the start. It’s not about how much you pay – it’s about what a spill will cost you if you don’t contain it right when it starts.

A

No, it’s not good enough. In six hours, the oil will spread and split over a large area, in an extremely thin layer. The volatile materials will evaporate quickly, while the rest of the oil coalesces and sinks down the water column. In short, the damage during these critical hours grows exponentially. Now, with HARBO’s system, you can have booms at work within minutes. That not only has a tremendous impact on the results of the spill but also a great effect on the public perspective.

A

Basically, there is no limit. It’s modular. Each 25m cartridge is connected to
The next. For example, when deployed, 40 cartridges will create a one-km-long boom.

A

The unique geometry and design make it possible. The T-Fence boom rides the waves rather than fighting them. The smart design creates very low drag, so wind hardly affects it. A regular boom has a curtain that is supposed to stop oil, but oil entrains under it.

A

The whole idea behind T-Fence is that you don’t have to drag it. You deploy it while encircling the spill. That said, T-Fence is towable. It comes with two powerful straps and special handles that allow you to move it around.

A

Its underwater geometry is angular, so oil cannot zigzag under it.

A

T-Fence underwent two separate weeks of successful tests at OHMSETT and was tested offshore at sea state 3 and 4 conditions. In all cases, it was found to be very effective.
