Decision to suit Berg EPL for EEXI resolution on 9 extra ships adopted pilot on 8,036 DWT Oslo Bulk 6
Oslo Bulk Shipping AS’s Bulkship Management subsidiary, which focuses on geared vessels, is to implement Berg Propulsion’s “EPL for EEXI” energy limitation resolution on 10 Oslo Bulk ships buying and selling in U.S. Gulf and Caribbean waters.
Berg Propulsion says the engine energy limitation resolution is of specific profit to the various ships whose efficiency requires solely average adjustment to fulfill IMO EEXI necessities. In drive from January 1, 2023, EEXI means homeowners should confirm {that a} ship’s attained vitality effectivity matches its “required EEXI” by its first subsequent survey.
Rather than utilizing a governor for engine derating or ShaPoLi (shaft energy limitation), Berg’s EPL (engine energy limiter) is a software-based resolution which works with the corporate’s MPC800 management system to restrict propeller pitch. Requiring no further sensors, indicators are despatched by the Berg EPL to the ship’s controllable pitch propeller (CPP), the place brake torque is diminished till the engine energy reaches its accredited vary. The data can be utilized to confirm that attained EEXI matches required EEXI, as soon as entered into the IMO information assortment system (DCS).
A pilot technical evaluation on the 8,036 DWT Bulkship Management vessel Oslo Bulk 6, indicated that EEXI wants can be happy by derating its principal engine to adjust to the brand new laws. Sea trials protecting the Berg EPL’s limiting impact on the ship’s Berg MPP950 CPP introduced DNV acceptance of the system’s efficiency as an efficient EPL resolution.
Bulkship has now confirmed orders to put in the answer on 9 extra ships.
On a CPP set up, it’s extra pure to restrict the engine energy output by the correct governance of the propeller than by limiting the engine rpm setpoint,” mentioned Magnus Thorén, gross sales supervisor vitality & effectivity at Berg Propulsion. “We use the main engine signal interface to limit the brake torque created by the propeller. Although it’s for a different purpose, this is based on the well-established practice of using a propeller pitch setpoint for overload protection.”
Using the Berg EPL, crew are at liberty to override the perform in instances the place full energy is required on a password-protected foundation, though exceeding the pre-set restrict would lead to computerized logging for later reporting functions, mentioned Thorén.
“Our newly released EPL adds to our growing portfolio of novel automation solutions integrated in our MPC800 control platform,” mentioned Jonas Nyberg, managing director – West, BERG Propulsion. “We are continuously developing new software solutions for our existing MPC800 control system, leveraging the platform already installed in the world fleet. Solutions include fuel optimization systems, hybrid controls and now EPL, among others.”
All 10 of the Oslo Bulk ships being fitted with the answer function Berg’s MPC 800 management system resolution, which is required as a place to begin for the Berg EPL resolution.
According to Thorén, the answer’s effectiveness has inspired one purchaser who was already upgrading its ship management techniques to MPC 800 management to specify that Berg EPL for EEXI also needs to be included.
