 Odfjell is upgrading the propulsion system for 19 vessels with new technology to optimise energy efficiency. The vessels will be equipped with new energy efficient propeller blades, rudder-bulb and will undergo technical upgrades of the main engine, turbo chargers and shaft generator. These combined upgrades will reduce fuel consumption and emissions by up to 20%.The vessels will be amongst the most energy efficient chemical tankers in the world, and will achieve the highest score on the Rightship energy rating, A+.20% – A major achievementThe initial model tests, which were carried out at Norwegian Marine Technology Research Institute (Marintek ), indicated a reduction in fuel consumption of about 15% for our series of eleven 37,000 deadweight (dwt) vessels (Kvaerner class). Sea trials before and after the upgrade show an overall efficiency gain of more than 20%. With such excellent result we will also upgrade additional eight 40,000 dwt vessels (Poland class). The concept has been developed by Odfjell, in close cooperation with MAN Diesel & Turbo, but also Grenaa Motorfabrik and ABB AS Turbocharging. The upgrade includes highly efficient Kappel propeller blades, fairing cone and rudder bulb, shaft generator gearbox and Odfjell determined settings.Dr. Kourosh Koushan, Research Manager at Marintek, acknowledges ...

 One of the first commercial applications of MAN Diesel & Turbo’s new MAN Alpha Kappel FP propeller took place off the coast of China recently when the ‘Elsabeth C’, a 58,500-dwt Supramax bulk carrier owned by Frontmarine Co. Ltd successfully completed its sea trials.The newbuilding is the first in a series of eight sister-ships, all featuring single MAN B&W 5S60ME-C8.2 engines with an SMCR 8050 kW @ 89 rpm. The Elsabeth C’s sister ship, ‘Mirela’, the second in the series, has since successfully completed its own sea trials.Lemissoler reports that the Kappel propeller offers significant fuel savings compared to conventional propellers and, together with the new vessels’ design and lines as well as the silyl acrylate antifouling paint, contributed to the favourable results from the first two vessels’ sea trials.It reports that both vessels consumed an average 23 mtns per day at a speed of about 14.2 knots in ballast conditions during the trials. The Elsabeth C also performed a successful crash-stop test that was notable for its lack of noise and vibration.Thomas Leander, Head of Propulsion – PrimeServ Four-Stroke – Denmark, said: “A key point during the design stage was to address the problem experienced by similar vessels that ...

Mr. Nobu SU, Chairman of Today Makes Tomorrow Group (TMT) successfully registered a patent in Singapore for Hybrid Ship, a hybrid technology that enables a variety of vessels, including bulk carriers, tankers, PCTC and LNG ships to enhance fuel efficiency.The innovation consists of a conventionally driven main propeller and an electrically driven duct propeller; the combination allows for reduced fuel consumption, particularly when a vessel is travelling with minimum ballast.The Intellectual Property Office of Singapore granted the patent on August 28, 2015. A patent was also granted by the Liberia Industrial Property Office back in January 13, 2014 for a period of 20 years. Several patents will continue to be pursued by Mr. SU and his partners, who made filings with 25 shipping nations in total.In respect of the latest patent registration, Mr. SU said,"I trust that as more patent offices register Hybrid Ship, the technology will be more readily adopted, which will help tackle problems associated with the transfer of harmful aquatic organisms and pathogens through ballast water. Such a transfer has already seen the Pacific saury affected - a species found in the subarctic and subtropical North Pacific that is regularly harvested by Chinese, Japanese and Russian fishermen. ...

 James Fisher Mimic (JFM) and the Engineering Department's Dr Xiandong Ma wanted to make ships ‘smarter’ through developing condition monitoring software – Mimic – to improve fuel efficiency and reduce unnecessary maintenance.As part of a ship-owner and operating company, JFM use their fleet and experienced personnel to develop a range of products focussing on maximising the use of technology to solve problems within the shipping industry. They provide condition monitoring software that allow companies’ maintenance decisions to be based on condition and performance rather than on recommended time basis, which reduces unnecessary maintenance.Scheduled maintenance costs are a large part of the operating expenses for ship owners; often seen as pure costs, with no immediate need or longer term benefits, which leads to many owners putting it off. However this eventually leads to more breakdowns, resulting in a higher overall cost.Monitoring and diagnostics of ships play an increasingly important role in optimal scheduling of maintenance activities. Condition monitoring has previously only been used for specific aspects of a ships system. Recently, there has been a growing interest in the monitoring of fuel usage and conditions of the whole ship which JFM seek to develop and include in their software – Mimic.Expertise ...

 Eniram Limited, announced the release of Eniram Performance 3.0, a data analytics software for cruise vessels. This tool offers real-time operational guidance to optimize a vessel’s overall energy management in order to save fuel. The system predicts required energy and fuel consumption taking into consideration a wide range of variables such as wind and currents for each specific voyage. (Image Credit: Eniram)Of particular importance is the Key Performance Indicator (KPI) screen that works like an electronic scorecard, showing traffic light values against commonly-agreed targets. The KPI screen starts with a high-level KPI, namely the total fuel consumption on the vessel which is then broken down to specific energy consumers like propulsion and service power. Service Power is for instance further split down to Hotel, Machinery and HVAC.Detailed analysis can also be viewed at all times onboard the ship. Easy-to-interpret benchmark graphs and reports help the crew to identify the key areas for savings potential by revealing performance deviations and monitoring selected performance parameters.The new version of Eniram Performance for Cruise vessels is currently operational on two vessels in addition to Quantum of the Seas. Now through the enhanced KPI feature, officers, engineers as well as onshore personnel can continually monitor, communicate and discuss ...

 Carbon War Room (CWR)  issued a request for proposals (RFP) to shipowners or charterers for a grant that will help finance a single-vessel retrofit with a bundle of proven technologies. The retrofit will result in a minimum fuel savings of 10–15%.Up to 200,000 USD will be granted by CWR to fund the installation of continuous monitoring equipment. CWR will also commission independent, third-party analysis of the collected data, which will verify the benefits of the multi-technology retrofit and provide a ‘proof of concept’ for the entire industry.CWR analysis of over 100 existing ships has shown that vessels can achieve efficiency gains of at least 10–15% by retrofitting with a bundle of proven energy efficiency technologies. These include advanced hull coatings, ducts, fins, and new propellers. This builds on a previous report by CWR, Hidden Treasure – Financial Models for Shipping Retrofits, which explored a viable financing model whereby repayment is tied directly to fuel savings.The grant will cover a portion of the total retrofit bundle, with at least 50% of the remaining technology costs to be financed by a third party. This project is funded by the Dutch Postcode Lottery, which recently awarded €1,000,000 to Rocky Mountain Institute and CWR ...

Many shipowners and operators are turning to bulbous bow retrofits to increase their vessels’ energy efficiency. DNV GL has developed a new tool as part of the ECO Retrofit service to support the industry in tailoring retrofit projects to the future needs of their fleet.While the service identifies new bow shapes based on computational fluid dynamics (CFD) calculations, the new tool explores the effect of alternative operational options. Overall, this approach can customers help save five to ten per cent on their annual fuel bill.The biggest issue in many retrofit projects is the definition of the individual operational profile. In the past two years the ECO Retrofit service has already helped to upgrade some 200 vessels. Aside from analysing their fleet’s past performance, shipowners and operators frequently have questions concerning the future, such as: What if I operate at other conditions some day? Can we change the operational profile again?“Even though our new ECO Retrofit tool cannot change the volatility of the market, it quantifies performance for a bandwidth of scenarios from worst-case to best-case scenarios, supporting more informed business decisions,” says Carsten Hahn, Senior Project Engineer ECO Lines at DNV GL – Maritime. DNV GL’s new ECO Retrofit service creates ...
