Maritime Transport

Maritime transport includes the transportation of cargo using vessels; this can be further subdivided into break and bulk cargos. Break cargo are goods that must be loaded individually, and not in containers nor in bulk as with oil or grain. The market segment that is of interest to Saltwater is the specialized break cargo sector, large and heavy cargoes that require a unique solution per individual case. The loading method can be a heavy lift, Ro-Ro or Flo-Flo configuration and in some cases even a combination of these methods.


Seafastening and supporting structures

When unique cargoes are transported, special attention must be paid to the supporting structures such as load spreading grillages and seafastening of the cargo to withstand the vessel motions. Saltwater has completed a huge diversity of maritime transport and seafastening calculations ranging from transition pieces to entire topsides with a weight in excess of 13.000 tons. One of solutions that meet the client and cargo requirements and fulfil the criteria set down by the marine warranty surveyors are challenges that our engineers gladly tackle.

Ro-Ro is an acronym for Roll-on/roll-off. Ro-Ro loading is an operation where the cargo is loaded onto the vessel using to wheeled transport system such SPMT’s (Self Propelled Modular Transporter). Ro-Ro cargoes can vary significantly in size and weight and involve detailed calculations during the loading operation such as ballast calculation to compensate for the load, mooring analysis and deck strength calculations.


As the acronym already suggest, Flo-Flo is a float on/float off loading operation. Basically there are two main types of Flo-Flo vessels in operation, the specialized semi-submersible vessels and standard pontoons that are modified to each loading situation. A floating cargo is positioned over the Flo-Flo vessel, the vessel then discharges ballast water and slowly rises lifting the floating cargo out of the water. The Flo-Flo operations involve calculations for ballast and stability as well as diverse strength calculations.
