Joe McCall explains that on the boats with this system, "Due to the constant speed of the engines while maneuvering, we have seen a reduction in the engine repairs. Constant acceleration / decelera- tion of the engines while maneuvering increases the thermal cycling of the engine as the vessel maneuvers. CSP has allowed us to run the engines at constant speed so we have reduced the wear on the engines. We have also seen a significant reduction in fuel consumption as CSP allows us to maintain position using less horsepower than conventional propulsion systems. This saves our customers money."
The system is tied in with the vessel's
CSP Inc. integrated electronic controls
These provide a full vessel monitoring system that allows all alarms and indica- tors to be integrated into a single display.
The system will alert the captain with either a visual indication, voice annunci- ated audible alarm or both. It also has an e-mail capability that can be utilized to notify a shore base of the alarm, and can take immediate control to alleviate the problem if conditions warrant. Õ À > L > ? ° ° ° ?

GREAT BOATS of 2005
Morgan Foss:
Harbor Tug
Foss Maritime's new harbor tug Morgan Foss is the second in the new series of designated Dol- phin Class tugs for Foss, designed by Robert
Allan Ltd. in collaboration with Foss' in-house engineering staff, and built in their own ship- yard in Rainier, Oregon. It will be used for ser- vice in Pacific Coast ports. This high-powered compact tug was the result of a collaboration between owner, designer, and builder alike. The tug is essentially identical to her cousin Mikioi, delivered in 2004. The tug is configured as a high-performance day-boat, with a compact wheelhouse atop a similarly compact deck- house which contains only the engine exhaust casings, vent intakes, and a small day-room and lavatory for the crew. The only deck machinery on the tug is an all-electric hawser winch, designed and built by Markey Machinery of Seattle. Designated as a Model DEPCF-48, the winch carries 600' of 8" circumference
Spectra/Plasma line, with a breaking strain of 500,000 lbs. The towline leads forward through a U-shaped heavy duty towing staple with a pol- ished inside face. Fendering comprises a heavy cylindrical bow fender, located above a belt of
Schuyler "Soft-Loop" style fender that extends around the full perimeter of the tug at the main sheer line.
The main engines are a pair of CAT 3512D diesels, each rated 2,365 bhp at 1,800 rpm.
These each drive a Rolls-Royce Model US 205 Z- drive unit, with 2,300 mm diameter four-bladed propellers. The drive-line comprises a hollow carbon-fibre shaft, enabling the complete elimi- nation of any intermediate shaft bearings.
The main engines are resiliently mounted on flexible mounts.
Electrical power is provided by a pair of Mit- subishi 6D16-T diesel gensets, each rated 125 kW at 1,800 rpm. Power output is 460 volt/3 phase/60 Hz.
