What Is TorqueSense ShaPoLi (Shaft Power Limiter)?
TorqueSense ShaPoLi stands out as a cutting-edge shaft power limiter, seamlessly incorporating the TorqueSense system for efficient power regulation. TorqueSense, known for its versatility, can be easily installed on any shaft, offering a significant advantage over traditional strain gauges. It plays a pivotal role in a comprehensive strategy aimed at boosting fuel efficiency and curbing greenhouse gas emissions.
The shaft power limiters are strategically employed to optimize power transmission within the ship’s propulsion system, ensuring the engine operates within its designated efficiency range. By averting excessive loads on the propulsion system during varying operational conditions, ShaPoLi minimizes fuel consumption, enhancing overall energy efficiency. This becomes particularly crucial for compliance with regulations like the Energy Efficiency Existing Ship Index (EEXI).
What Is EEXI, and What Role Does ShaPoLi Play in It?
The EEXI Regulation, a component of the International Maritime Organization’s (IMO) measures to combat greenhouse gas emissions in shipping, establishes efficiency standards for existing ships. As of December 2023, all operational merchant, cruise, and ferry vessels with a gross tonnage exceeding 400 GT* engaged in global trade are mandated to adhere to the specifications outlined in the International Maritime Organization’s Energy Efficiency Existing Ship Index (EEXI). This index sets a baseline for the minimum energy efficiency standards these vessels must meet (applicable under the jurisdiction of MARPOL Annex VI).
Ships surpassing specified emission thresholds must implement measures to enhance their energy efficiency, and optimizing power transmission through the use of shaft power limiters, such as ShaPoLi, is a key strategy. By aligning with EEXI requirements and improving fuel efficiency, ships can reduce their carbon footprint, contributing to sustainable maritime practices.
