To transfer people and cargo safely and easily to and from an offshore structure, SMST has developed a range of motion compensated gangways, the Telescopic Access Bridges (TAB) – S to XL series, that vary in length from 4 to 58 meters. The movements of the gangways can be passively or actively compensated. All bridges can be deployed for cargo handling and are available for purchase or rent.

Since jobs and vessels vary all the time, SMST offers flexibility to the offshore industry by providing access solutions consisting of modular components, suitable for all possible operational conditions. The modular setup of the gangway M series (TAB-M) makes operation for specific project set ups possible. This gangway can consist of stacking modules for various height adjustments. The active motion compensation ensures high workability.

For safe and stepless transfer of people and cargo, the motion compensated gangway L series can be combined with SMST’s Access & Cargo Tower. This logistic solution integrates a bridge, tower and elevator system, enabling working on various heights in all kind of weather conditions.

For operation of the gangway, the vessels own operators are instructed by SMST. SMST provides qualified training on board or using the training simulator at their premises in Drachten (the Netherlands). SMST offers worldwide service and availability for its equipment.
