NEW REPOWER OF PACIFIC MARITIME GROUP’S TUG HARBOR CAPTAIN
The 42’ ft tug Harbor Captain was built in San Diego, CA in 1997, with major re-builds in 2006 and most recently in 2021. The vessel is owned by Pacific Maritime Group, Inc, dba Pacific Tugboat Service, headquartered in San Diego, California.
Pacific Maritime Group is a well-known Marine Services, Dredging and Construction Company. The re-power of the Harbor Captain with Mitsubishi engines makes for the second Mitsubishi powered vessel in our fleet. We have scheduled over the next 10 months four (4) additional tugs that are also being re-powered with seven (7) Mitsubishi engines ranging from 500 hp up to 1,600 hp each.
The Harbor Captain was last re-powered in 2006 during a major refit with a pair of Tier 2, MTU S60 engines.
Our 2021 re-power used two (2) new EPA certified, Mitsubishi S6A3-Y3MPTK-4 Tier 3 engines with keel cooled water jacket and aftercooler circuits. Each engine produced 500 hp @ 1800 rpm through Twin Disc MGX-5136-SC 2.90:1 gears turning (2) 4 blade 39”x 46” fixed pitch props fitted in Kort nozzles.
Pacific Tugboat Service selected the Mitsubishi engines because they provided similar horsepower and engine speed, allowing us to utilize existing shafts and propellers.
We chose Southern California Mitsubishi dealer Dee Finley Diesel Repair to supply the Mitsubishi engines from Cascade Engine Center, headquartered in Seattle, Washington. Dee Finley also provided considerable technical assistance to PTS throughout the repower.
PTS Port Engineer Peter Walding and Port Capt Tom Ebner led our in-house construction team to simultaneously perform upgrades and maintenance to the vessel during the re-power.
US Coast Guard Sub Chapter M certification was also obtained at completion of the repower/refit.
Pacific Tugboat Service has also selected Mitsubishi S6A3-Y3MPTK-4, 18.6 liter, 500 hp engines to replace two 14.5 liter Tier 2, MTU S60 engines in our PTS designed and constructed push Tug Harbor Commander, currently undergoing re-power. PTS will also add to our Mitsubishi fleet by selecting a new S16R-Y3MPTAW, 1600hp engine for our ocean going Tug Blarney and two pairs of S12R-Y3, 1100hp engines in our tugs Hidalgo and Bass. The mechanically controlled, Tier 3 Mitsubishi provides less complex maintenance as computers are not required and the large Mitsubishi displacement provides PTS vessels with reliable power.
