The brand-new regulative structure (Energy Efficiency eXisting ship Index– EEXI) around carbon dioxide discharges for existing delivery entered into pressure in January 2023 and also lots of shipowners are currently taking into consideration exactly how to fulfill these with either functional modifications or technological modifications.

Windship Technology releases exclusive research study that permits ship drivers, proprietors and also charterers the capacity to conveniently see the favorable, game-changing functional impact that setting up simply one 36m gear can carry their vessel moving forward.

These policies look for to determine the performance of ships with the quantity of carbon dioxide produced per tonne per mile of products lugged in a year. Ships will certainly be ranked yearly, from A, the greatest executing, to E the most affordable and also the outcomes will certainly be taped in the Ship Energy Efficiency Management Plan (SEEMP). Ships ranked D for 3 successive years or E for a solitary year require to create an accepted restorative activity strategy as component of the SEEMP.

The International Maritime Organisation (IMO) have actually presently established a 2% decrease annually on Carbon Intensity Index (CII) demands till 2025, whereupon the decrease will certainly require to boost to obtain in the direction of the general IMO carbon dioxide decrease objectives of 2050.

Wärtsilä have actually reported the outcomes of their CII Insight device, which has actually forecasted that when CII enters into pressure, concerning 45% of the fleet is anticipated to be in classification D, with an additional 16% in classification E. They additional anticipate that, if absolutely nothing is done and also thinking the IMO trajectory remains consistent, by 2030, 81% of the bulker fleet, 57% of vessels and also 80% of container ships will certainly remain in classification E.

The most typical technique to accomplishing conformity since 2023 is to lower the rate of the vessel with engine power restriction (EPL), which will certainly lower the quantity of gas per tonne per mile utilized, as ship resistance is symmetrical to the dice of the rate of the vessel. For some vessels this will certainly be a temporary service, for others the EPL needed possibly considerable, possibly implying the engine will certainly be running well beyond its excellent criteria.

Apart from functional modifications such as EPL, proprietors can carry out technological performance enhancements, and also it’s right here where the noticeable installion of Windship Technology’s trademarked, high-performing gears are most reliable. The efficiency of the Windship 36m gear has actually been determined making use of computational liquid characteristics (CFD). This efficiency information can after that be integrated with the EEXI wind matrix to make it possible for the decrease in EEXI for an offered vessel to be examined.

Windship Technology have actually performed this analysis for a series of vessel DWT (Deadweight tonnage) to supply proprietors with an overview regarding the effective impact a solitary 36m gear might carry their ship. This modern technology can be utilized together with EPL if needed to attain conformity. A more advantage of this technique would certainly be to think about including a 2nd gear, if eventually the CII needed even more decreases. Clearly the last EEXI decrease will certainly depend on real ship efficiency attributes, nevertheless the chart supplies an excellent indicator of the possibility.

Simon Rogers, Technical Director of Windship Technology is clear concerning the advantages: “This is a known issue that is fast coming down the track and one that ship operators must start addressing. What we have developed with our patented, high power rig design is a solution that works in tandem with existing EPL measures but greatly enhances performance. Our assessment is an EPL reduction of some 20-25% depending on the size of the vessel and not only are we extending the operational life of the ships that install Windship Technology rigs but we are making global shipping compliant and faster.”

Graham Harvey, Chief Executive of Windship Technology even more included: “It’s very clear from the chart below the positive effects that installing our patented rigs has on performance. Owners, Operators and Charterers are all highly aware of the regulatory framework that is close to being imposed by the IMO and time is running out to achieve compliance. We are hosting a broad range of discussions with key players in the industry now and it’s very clear that Windship Technology is very much part of the solution going forward. We welcome further enquiries and discussion from interested parties.”
