Machinery control and monitoring Multiple engine displays
with 4161 Oceanic Systems is currently promoting its 4161 Multiple Engine Display, designed to display all critical engine data in real time. Once installed onboard, the user can utilise the display to check the status of up to four engines and four fuel tank levels, as well as info related to current steering angle and GPS.
The 4161 Multiple Engine Display can display the status of up to four engines and four fuel tank levels
format;
Te 4161 display comes in a 19”- (482.6mm-) wide features glare-proof and dimmable colour
graphics; has NMEA 2000 and J1939 built-in interfaces; and is compatible with Caterpillar, MAN, MTU, Volvo, Cummins and Yanmar inboard engines, as well as Mercury, Evinrude, Honda and Yamaha outboards. Oceanic Systems comments: “Choosing the engine manufacturer to display is done by setting a switch on the rear of the unit. Tese displays understand and present engine manufacturer’s error codes as they occur, to ensure that they do not compromise the selected engine manufacturer’s warranty.” In future, Ocean Systems expects to extend the
display’s capabilities to 16 manufacturers apiece for inboard and outboard engines.

Power generation and management Triskel launches generator
replacement technology Cornwall, UK-based marine data and energy management technology specialist Triskel Marine launched its latest product, the Integrel generator replacement system, at Southampton Boat Show in September. Te system is, in essence, a high-powered alternator which uses soſtware programmed with data on the vessel’s propeller, hull characteristics and engine fuel map to generate electrical power for use on board. The system has been 10 years in the making,
first sparked by data gathered as part of the 2008, EU-funded HYMAR research project
into hybrid
marine propulsion, which also revealed implications for research into power generation, storage and distribution. As Ken Wittamore, managing director of Triskel Marine,
12 Triskel Marine reports several benefits in using the
Integrel system compared to a standalone generator, including onboard space-saving and the reduced maintenance costs involved in keeping the system running (according to Triskel, all that should be required is that the alternator belt be changed during servicing). Tere is also a significant fuel saving, Triskel claims. Wittamore points out that as engine efficiency varies considerably throughout the operational cycle, and as different engines’ operational cycles differ wildly, calculating fuel saving is not easy. However, he reveals that the overall fuel saving typically observed is “around 25% depending on the duty cycle of the vessel; vessels with a highly variable operational profile benefit the most.”

Triskel’s test rig in its workshop in Hayle, Cornwall, has put the Integrel system through its paces
explains, data from the project “validated the underlying principle of the current Integrel system, which is that the main propulsion engine has a large amount of unused capacity for much of the time”. By making real-time calculations of the diesel
engine’s “spare” capacity, the Integrel system can intelligently add load to the engine to maximise efficiency, while generating power for immediate onboard application, or to charge battery banks. According to Triskel Marine, the system always “prioritises propulsion” and avoids shock loading the engine by ramping electrical power gradually. A viable iteration of the system has existed for three
years, and has undergone testing on vessels at sea throughout that time. With minor modifications, the system in its current form has been in use on Triskel Marine’s own boats for the last two years, and on the first customer’s vessel for one year. Wittamore stresses the importance of this real-world testing, saying: “Tese conditions are simply not repeatable ashore, and the trials have proved that the system that we have produced is fully operable and effective in the worst that Northern waters can throw at us.”
