Wärtsilä Trim optimised by Eniram

Optimizing a vessel’s trim cuts fuel consumption and CO2 emissions. But unlike static trim charts, Wärtsilä Trim allows you to respond immediately to changing conditions and maintain optimum trim in real time. Our analysis is based on a unique model of your vessel’s hydrodynamic characteristics, information gathered by attitude sensors installed on the vessel hull, and vessel automation and bridge systems.

The Wärtsilä Insight Factory uses advanced algorithms to understand the effect of constantly changing variables like trim and list, sea state, draft and tank levels, speed through water, and propulsion power and RPM. These inputs allow Wärtsilä Trim to calculate the optimal trim in real time – leading to lower fuel consumption and cost savings compared with traditional trimming methods.

    Key benefits

    • Ensure optimum trim with clear onboard recommendations
    • See the trim reading at a glance
    • Establish and improve trim best practices by utilizing insights from trim reports and Wärtsilä fleet

    Case: Save fuel with Wärtsilä Trim

    Wartsila Trim Case

    A Panamax size cruise vessel had been sailing 30-40 cm off optimum trim. On average, 25 cm off trim equates to 2% in propulsion power on the vessel type in question. Had the vessel been sailing at optimum dynamic trim, it would have saved 700 tons of fuel over a 12-month period. Based on an HFO cost of $600 per ton, this equates to an annual saving of $420,000 – a significant impact for a change of just a few centimeters.

    How it works

    The Insight Factory

    Our sensors continuously collect information about trim, list, bending, and sea state, which is combined with data from bridge and automation systems.

    The data is continuously analyzed with our advanced mathematical models tailored to each unique vessel to idenfity the optimum trim for the given vessel in the given conditions.

    The optimum trim is displayed on the bridge and the teams are kept up-to-date with mobile notifications, Wärtsilä Fleet, and Wärtsilä Trim reports.
