Gangway access systems

Más de 1000 pasarelas de acceso for oil and gas terminals in 70 countries around the world. Since supplying the first gangway system in 1966, we have developed a large number of standard designs, which are flexible to be adapted according to specific customer requirements.

Basically there are three main designs:

 
  • Tower gangway type, with a telescopic gangway that moves vertically along the tower by means of a lifting platform. Thanks to its lifting platform, the tower gangway can cover all levels of the ship deck, from small barges to ultra-large crude carriers, in combination with ship movements resulting from tidal movements, loading and unloading, and wave movements
  • Column gangway typewith a telescopic gangway at a fixed height. The column type is suitable for reaching ship deck levels from well below to a maximum of approximately 18 meters above the jetty deck
  • Riding ladder can be used when the variation of ship deck levels is limited and sufficient space is available on the jetty deck

Due to their proven and robust design, all our access gangways have a long service life and low maintenance cost.

Access gangways are widely used in the oil industry.

Tower Gangway Type

La Torre de acceso tiene una pasarela de acceso telescópica que se mueve verticalmente a lo largo de la torre por medio de una plataforma elevadora. Como resultado, la pasarela-torre puede cubrir los niveles de la cubierta de los barcos, desde las pequeñas barcazas hasta los ultra grandes buques de transporte de crudo, en combinación con los movimientos del barco (mareas, carga/descarga, deriva, etc.). Se puede acceder a cada estación de elevación por las escaleras de acceso y las plataformas montadas en el interior de la estructura de la torre.

Once the gangway has been positioned on the vessel deck and reaches its maximum up or down angle, the lifting platform will automatically move to the next level, without the presence of an operator. Prior to this movement, an alarm will alert all personnel to clear the gangway. Also the wave and rolling movements of the ship will be followed freely within its design range.

The gangway movements 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 Gangway Type

La columna tiene una plataforma giratoria a una altura fija a la que se puede acceder por escaleras de acceso montadas al lado de la estructura principal. La pasarela de acceso telescópica está montada en la plataforma giratoria y, tras su colocación en la cubierta del buque, seguirá libremente todos los movimientos dentro de su rango de diseño sin necesidad de que esté presente un operador. El tipo de columna es el diseño más popular para alcanzar los niveles de la cubierta del barco desde muy abajo hasta un máximo de unos 18 metros de alcance vertical.

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

The column type can be optionally 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 major benefit of the Column design is that it has a small foundation plate, which requires very little space on the jetty deck.

Riding ladder

Riding ladder systems vary in design from manual to fully hydraulic or electric. Typically, the ladder system has a fixed length. The sway motion of the vessels is compensated by the riding motion.

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