Canada's Most Powerful Tug Built With ShipConstructor

As a 100 metric-ton bollard pull ice class tug, the OCEAN Tundra is reportedly the most powerful harbor tugboat to ever be built in Canada.

SSI's ShipConstructor CAD/CAM application was used to construct this vessel. SSI client Robert Allan Ltd. produced the design and SSI's dealer, Navware, and the associated marine engineering firm, Navtech, worked with OCEAN Industries during the production design and engineering of the tugboat.

The project was so successful that OCEAN Industries decided to standardize on using ShipConstructor for future projects. This is a natural evolution from the company's previous reliance on generic AutoCAD products.

In particular, Ocean Industries was impressed with how ShipConstructor is a specialized shipbuilding application with productivity enhancing features for facilitating engineering and construction. The software's advantages regarding 3D modeling, piping, electrical cables and ventilation were noted. Also, Ocean Industries appreciated ShipConstructor's capabilities for the automatic generation of manufacturing bills of materials, the ability to automatically number parts for cutting and assembly, and the ability to create a build strategy for the construction of the ship. OCEAN Industries found that these features really paid off in terms of increased productivity in the shipyard.

Philippe Filion, OCEAN's Director of Public Affairs and Business Development said, "The OCEAN Tundra has benefited a great deal from the ShipConstructor products. Having a nearly perfect steel package saved us quite a bit of time assembling the ship with a limited number of people. On this project, we have, for the first time, eliminated all cutting at the ship and included all edge preparation to the nestings."

The enormously positive results on the OCEAN Tundra project are one example of what SSI calls Empowered Engineering; the creation of an accurate and detailed virtual model of the vessel in Engineering leads to benefits throughout the shipbuilding process.

For instance, as noted by Philippe Filion above, the OCEAN Tundra project showed how managing penetrations in the 3D model resulted in steel plate penetrations that were accurately cut in advance on a burning machine. In the past, these penetrations were often field cut by a tradesperson with a cutting torch in less than ideal circumstances.
