Shaft Power Limitation system, developed in conjunction with SELMA, optimises tanker engine output ahead of impending EEXI regulations.
Lloyd’s Register has approved the first Shaft Power Limitation (ShaPoLi) system that will be fitted onboard a 319,000 dwt very large crude carrier Aragona, operated by Neda Maritime Agency.
The system, which was developed by SELMA in conjunction with Tankers Technical Department of Neda Maritime Agency Co Ltd, will enable the full use of available engine output under impending EEXI (Energy Efficiency Existing ship) regulation.
The ShaPoLi system utilizes the propeller shaft torque and rotational speed sensors to calculate and automatically limit the developed power to comply with the LR approved Technical File, whilst providing recording and emergency overriding facilities, in line with MEPC335[76] regulation.
“With EEXI regulation at the doorstep, there is an increasing challenge around efficiency, and we are proud to offer our expertise, ensuring that our clients will best address the upcoming requirements safely and efficiently,” said Haris Fanaradellis, South Europe Technical Support Office Manager for Lloyd’s Register.
“The SELMA ShaPoLi system is a pioneering intelligent control system that provides a robust and viable method of controlling the developed shaft power, seamlessly interfaced with the vessel’s existing main engine control, while simultaneously maintaining original safety features. The system contributes to fuel consumption improvement and in turn to CO2 emissions reduction,” said Dr Panos Deligiannis, Tanker Technical Director at Neda Maritime Agency Co Ltd.
Guidelines for the development of a shaft/engine power limitation were adopted by MEPC335[76] in June 2021 as part of the International Maritime Organisation greenhouse gas emissions reduction short term strategy.

About Selma
SELMA is an engineering/manufacturing company established in 1987 specializing in the design, development & installation of advanced marine control systems.
SELMA in 2012 released SEES Ship Energy Efficiency System an intelligent control system based on VFDs Variable Frequency Drives to reduce vessel’s fuel consumption and its emissions (average fuel saving 120-150 tons/per year), by reducing the electrical load (average power reduction 100-150kW) through optimal control of Cooling Sea Water Pumps, E/R Fans & Aux. Boilers Condenser Pump.
SELMA in 2014 developed SEEMS/DAS (Data Acquisition System) a high-end integrated monitoring and data collection system for all types of vessels. Its purpose is to provide a complete solution for the data acquisition and remote monitoring of important vessel operational parameters allowing shipping owners to conduct full vessel performance analysis and benchmarking of its actual operational efficiency and to implement predictive maintenance strategies and schemes.
SELMA in 2017 developed an Intelligent Flettner Rotors Control / SCADA System on the world first Wind Assisted Propulsion Bulk Carrier MV AFROS (LR awarded as ship of the year for 2018)
SELMA in 2021 designed especially for NEDA tankers fleet ShaPoLi Shaft Power Limiter (LR Approved) to meet new IMO MEPC 76 MAPROL requirements that will be enforced from 01/01/2023.
