Dutch logistics company XELLZ has developed the ReelFrame™, as a solution to transporting heavy cable drums or reels without the use of cranes when loading and offloading trailers at factories, storage places and at the job site. It has now received the first patent for the ReelFrame technology.

XELLZ is attempting to stabilise and make light work of one ongoing transportation challenge for the energy industry with their latest innovation. According to XELLZ, the concept has not been used before.

The concept for the cable drum transport is firstly to remove any and all lifting requirements, with the exception perhaps of lifting in and out of a river barge or sea vessel. The ReelFrame™ means that cable drums up to 100mt no longer need to be loaded for transport with a crane. Operational costs are now much lower, the process is safer, takes less handling, and allows for a quicker turnaround.

The prototype has already been manufactured and is the perfect solution for all onshore HV cable projects, and has received positive responses from project owners, cable manufacturers, and transport companies alike.

The ReelFrame™ invention can transport a cable drum or reel by means of a road truck and multi-axle trailer combination, with the cable drum supported by a frame and a high-voltage cable.

What this looks like is a cable drum supplied with a high-voltage cable, held in a frame that allows for the rotational motion of the cable drum. A road truck and trailer that includes a front trailer and a back trailer transports the frame holding the cable drum. During transportation, the frame is coupled to the trailer so that it connects between the front trailer and the back trailer. The width of the frame is reduced in size for transport by bringing the sides in an upwards position hydraulically.

The frame holding the cable drum can be unloaded by decoupling it from the front and back trailer parts. Decoupling takes place after lowering the frame without the requirement of cranes. As the frame is transported in between both trailer parts, unloading can be achieved without using more space than the area already covered by the truck, trailer, and frame during transport. This reduces the disturbance caused by transporting cable reels for a high-voltage cable at construction and job sites where the cables are placed/pulled.

The frame is designed with a dual purpose, firstly for holding the cable drum in a rotatable manner so that a high-voltage cable can be wound or unwound and secondly for transportation in between trailer parts.

Peter Bouwhuis, CEO, XELLZ says “The design of the ReelFrame™ is such that the weight of the frame and the frame connector is at an absolute minimum. We are keeping it light and practical while maintaining the structure’s strength and integrity. For a frame that could transport a 100 metric tonne cable drum, the total weight is only seven metric tonnes.”

The ReelFrame™ is equipped with GPS and GPRS tracking as well as shock absorbers and cable consumption sensors.

The frame adapter weighs approximately seven tonnes and is connected to the frame by means of slip-slots or keyhole connecting points, and lock. When the frame adapter is connected to the trailer end, it will drive towards the ReelFrame™ and can be modified to the right height by adjusting the multiple-axle trailer hydraulic system. By bringing the trailer upwards and using the hydraulic system, the frame pins will slide into the pinhole locking to the adapter, then it is ready for transportation.

According to Bouwhuis, project requirements are often steered towards the use of longer cables which results in larger cable drums with weights reaching 100 metric tonnes per drum or more. This in itself poses the challenge of offloading such a cable on site, requiring a crane of at least 250 to 800mt lifting capacity, depending on the location of the crane and the reach required to place the drum on the job site. A challenging task when job sites are typically not spacious and creating a larger site is costly if not impossible. Using heavy cranes also requires the surface to be compacted in such a way that it can withstand the forces that such cranes will bring on the site.

“The ReelFrame™ is going to be a game-changer for the cable industry, transportation and logistics businesses. Not only will it save time and space on projects, teams are really going to enjoy working with this well-engineered but easy-to-use piece of kit,” says Bouwhuis.

Investments for the facilities at Damen Shiprepair Curacao, the largest shipyard in the Caribbean, are expected to proceed shortly. The shipyard located on Curacao near the coast of South America is owned by the government and since 2017 has been leased to Damen. The shipyard recently undertook the first project, which was an investment of approximately $1.1 million for the overhaul of the door on one of the yard’s four dry docks. In anticipation of the approval for a broader...

As sanctions and international isolation begin to take hold for Russia's oil industry, it has begun discounting prices in order to entice new buyers in far-flung markets. But in doing so, according to market intelligence firm Vortexa, Russia has begun to compete directly with Iran and Venezuela for a limited market in undercover oil.  One of the key signs is the movement of fly-by-night tankers from the sanctioned Iranian oil trade into the previously above-board Russian oil export market. According...

The first large cruise ship bunkered with a blended marine biofuel making the latest expansion of biofuel which has drawn wide support in the commercial shipping industry. The bunkering took place with Carnival Corporation’s AIDA Cruises aboard the AIDAprima and provides a blueprint for the wider cruise sector adoption of alternative fuels. AIDA has long been the pioneer within Carnival Corporation testing made of the new concepts for alternative power and improving environmental performance. The 125,500 gross ton AIDAprima became the...
