Gangway platform

Telescopic access gangways for ships
More than 1000 ground access gateways for oil and gas terminals in 70 countries around the world. Since the supply of the first gateway system in 1966, we have developed a large number of standard designs, which are flexible to be adapted according to specific customer requirements.

There are basically three main designs:


Tower walkway, with a telescopic walkway that moves vertically along the tower by means of a lifting platform. Thanks to its lifting platform, the gangway-tower can cover all levels of the ship's deck, from small barges to ultra-large crude oil carriers, in combination with tidal movements of ships, loading and unloading and wave movements
Columna Gangway, with a telescopic gangway at a fixed height. The column type is suitable for reaching the levels of the boat deck from very low to a maximum of approximately 18 meters above the dock deck
Mounting Ladder can be used when variation in boat deck levels is limited and sufficient space is available on the dock deck
Due to their proven and robust design, all our access gateways have a long service life and a low maintenance cost.

Access gateways are often used extensively in the oil industry. Can be ATEX certified.

Tower Type Access Gangways
The access tower has a telescopic access walkway that moves vertically along the tower by means of a lifting platform. As a result, the gangway-tower can cover the deck levels of ships, from small barges to ultra-large crude oil carriers, in combination with ship movements (tides, loading/unloading, drifting, etc.). Each lifting station can be accessed by access stairs and platforms mounted inside the tower structure.

Once the gangway has been placed on the deck of the ship and reaches its maximum angle of rise or descent, the lifting platform will automatically go to the next level, without the need for an operator to be present. Before this move, an alarm will alert all personnel to clear the walkway. Also the wave and roll movements of the boat will be freely tracked within its design range.

The movements of the gangway are driven by hydraulic cylinders, operated by a hydraulic control box mounted on the lifting platform. The movement of the lifting platform is driven by a lifting device (winch or hydraulic cylinder).

The Gangway Tower has many optional features such as crane, fire monitor, control cabin and cover for the protection of its users against, for example, extreme weather conditions. Other customer-specific requirements can also be integrated into the design of the Gangway Tower.

Column Type Access Gateways
The column has a turntable at a fixed height that can be accessed by access stairs mounted next to the main structure. The telescopic access gangway is mounted on the turntable and, after being placed on the deck of the vessel, it will freely follow all movements within its design range without the need for an operator to be present. The column type is the most popular design to reach the levels of the boat deck from very low to a maximum of about 18 meters of vertical reach.

The movements of the gangway are driven by hydraulic cylinders, operated by a hydraulic control box mounted on the control platform.

The column type can optionally be equipped with crane, lighting, alarms, fire monitoring and/or cabin. Other customer-specific requirements can also be integrated into the design of the walkway column.

The biggest benefit of the Column design is that it has a small foundation plate, which requires very little space on the dock deck.

Assembly Ladder
Stepladder systems vary in design from manual to fully hydraulic or electric. Typically, the ladder system has a fixed length walkway. The rocking motion of the vessels is compensated by the horseback riding motion.

In general, the assembly ladder is more economical in design compared to tower and column designs with similar operating envelopes, but requires much more dock space.
