Designed for construction in less sophisticated yards where forming plate is more difficult, the FacetTug is an innovative hull shape developed by OT&BE, created solely from faceted plate sections, and has no curvature in any plating. The design allows for the tug to be created from easily handled, pre-fabricated sections, and makes the creation of double-skin fuel tanks significantly easier. 117 foot versions of the design are being built in both 4,000 HP conventional drive and 5,000 HP diesel electric drive variants, both twin screw. The design has been fully tank tested, and the development of the initial shape was verified by extensive CFD studies.
