The final vessel in the latest batch of thirteen Z-Tech 6500 tugs for the Panama Canal has been completed, and it follows an eight vessel order, almost identical in configuration, completed for ACP (the Panama Canal Authority) in 2008. The latest batch of thirteen tugs are powered by larger, GE 12V228, 2965hp engines, increasing bollard pull capabilities to 65t, from 60t previously.

With delivery for this final unit contracted to take place in Panama before the end of February 2012, this December 2011 delivery, ex-yard Hong Kong should result in contract completion ahead of schedule.

The GE engines drive two Schottel SRP1515FP azimuth rudder propellers containing 2.6m diameter 5-bladed fixed pitch propellers. The configuration provides a free running speed of 12.5 knots, both ahead and astern. Two Deutz 112kW diesel generating sets maintain all onboard electrical loads, while the starboard side main engine drives the FFS 1136m3/hr fire pump that supplies a fire monitor mounted on the wheelhouse top.

The two towing winches and capstan are from MacGregor.

Z-Tech series tugs are typically operated by a captain and crew of three, although accommodation arrangements vary slightly, depending on operator preferences. Accommodation for the Panama vessels is for a crew of four, a 2-man crew cabin on the lower deck as well a single officer cabin and engineers cabin/office on the main deck, along with the galley and crew mess. The wheelhouse above has 360 degree visibility through full height glazing all-round.

These thirteen Cheoy Lee Z-Tech 6500 tugs built for Panama are constructed to Lloyds Register​ class, with the class notation LR +100AN Tug, +LMC, UMS for service in the Panama Canal and Approaches.

Principal Dimensions: 27.40m LOA x 11.50m Beam x 5.83m Draft.
