Our Work

CAT 398 – (4) total Main Generators – Electric Propulsion.

Removed a cylinder head to find out the head dropped a valve so the cylinder pack and head were changed out. Test ran unit to ensure everything was working properly.

Changed out the governor drive coupling and all the jerk pumps were installed. All fuel nozzles were changed out as well. Performed a failure analysis to figure out why the #6 main bearing spun.

Performed (2) center section & top end overhauls including main bearings, cylinder packs, heads, front & rear main seals and cam bearings. Performed (4) hour sea trial to ensure that both CAT 3508 engines were running properly.

Bay Power sent 3 of their veteran technicians to Ketchikan Alaska to perform 3 center section & top end overhauls simultaneously, including main bearings, cylinder packs, heads, front & rear seals and cam bearings. Performed a 4-hour load bank test on each generator. The CGC is a 175-foot vessel that maintains aid to navigation and conducting multiple Coast Guard missions within the coastal waters of Southeast Alaska. This overhaul took less than a month to complete.

This job originally started as an inspection and turned into a complete engine overhaul. Bay Power received the call and had 2 days’ notice to get a three-man team ready and overseas to board the ship. While the ship was underway the engine overhaul was completed which included: brand new OEM heads, liners, pistons, rods & bearings, marine head bearings and they also rebuilt the injectors and fuel pumps. The engine was disassembled on the ships East Coast route, parts were ordered and picked up upon the ships return to Europe where our technicians began the rebuild stage of the engine.

Performed in-frame overhaul, replaced all cylinder kits incl. pistons, rods and liners after inspection. Replaced front and rear crank seals. Replaced cylinder head with new. Ran engine 2 hours with no load and then 3 hours under load. Engine is in complete working order.

Fuel Reduction; Electronic Engine vs. Mechanical Engine

The Night Falcon and Captain Ted are both busy push boats, moving material barges of either sand or gravel between Havre de Grace, MD, Woodbridge, VA, Brooklyn, NY, and Seaford, VA. Three strong factors steered the owners to choose Mitsubishi engine over two well-known brands.

• Mechanical engines that meet EPA tier requirements providing important operational simplicity over electronic engines.
• Lower fuel consumption (35%-40% reduction) than other engines will provide major long-term reductions in cost of operations.
• The cost of Mitsubishi engine was very competitive

The reduction in operating costs is living up to expectations, with the Mitsubishi engines using 30 fewer gallons per hour than the old engines. While the old engines were burning 80 GPH, the new Mitsubishi engines have been consuming just 50 GPH, doing the same work. Additionally, the new mechanical engines respond very well and emissions have been reduced by an estimated 90% Vulcan Materials plans on adding more of these engines to their fleet in the future.

The Spirit of Washington is a dining and entertainment cruise ship, one of many “Spirit” ships owned by City Experiences/Hornblower. With tours of the Washington D.C. area, Norfolk, New York, and more, the ship can hold it up 600 passengers. To maximize the dining and entertainment space on the ship, there are four levels to accommodate guests. Due to the tall height and short width of the ship, there was a need for more control when docking the ship. Often navigating close quarters on the Potomac River, the Spirit of Washington needed to increase the vessel maneuvering and handling capabilities.

Bay Power Solutions was a key team member in the solution. To increase the vessel handling capabilities, Spirit needed to increase the size of their bow thruster and install an engine large enough to power the new system. Spirit came to Bay Power Solutions because of By Power’s ability to see projects as a whole, anticipate potential problems and work through them quickly to keep production on schedule. Bay Power Solutions worked with Spirit’s marine architect and determined that the Spirit’s current engine needed to be upgraded to a new emissions compliant 6068SFM50 John Deere engine. Due to the distance from the Pilot House to the engine room (approx. 180 feet), a Microprocessor-Based Engine Management System would be required to effectively implement the upgrade. Provide full control and engine monitoring in the Pilot House and wing stations, the microprocessor was a necessary addition to fulfill the Spirit’s need for increased vessel handling capabilities.

Bay Power Solutions was able to assist the shipyard and Spirit with the complete upgrade in just over a month, allowing the vessel to have a minimal downtime.
