To date, more than 60 new build ships feature Promas with close to 40 already retrofitted ...

The first Wärtsilä X62 two-stroke engine has successfully passed its design validation and type approval tests and has performed exceptionally well during the necessary sea trials. It is, therefore, now ready for full market availability. The Wärtsilä X62 is the latest in Wärtsilä’s X-Generation of engines that was introduced in 2012 and which has been well received by the marine sector. Thus far orders have been received for 127 X-Generation engines. These engines feature a high stroke-to-bore ratio, thus achieving a lower engine speed and reduced brake specific fuel consumption (BSFC). Most prominently, the X62 incorporates Wärtsilä’s second generation electronically controlled, common-rail fuel injection system. The system facilitates high levels of combustion efficiency to give exceptional fuel savings across the entire load range of the engine. Another important feature of the Wärtsilä X-Generation engines is that a single electronic control system, the Wärtsilä UNIC, controls the fuel injection, the exhaust valve operation, and the cylinder lubrication. This allows excellent flexibility in the optimised operation of the engine. The first Wärtsilä X62 engines to enter actual service will be used to power four 115,000 dwt LR2 product tankers being built for the Greek ship owner Kyklades Maritime Corp at the Gunsan ...

When Detroit Brasil Ltda., a local shipbuilder in Brazil, was looking for a partner to achieve reductions in fuel expenditure and CO2 emissions, they turned to GE. GE’s Power Conversion business announced that they will provide dynamic positioning (DP) and vessel control systems to equip the next generation platform supply vessels (PSV4500), currently under construction at the Detroit shipyard to the Brazilian shipbuilder Starnav Serviços Marítimos Ltda. These vessels, the first of which will be commissioned and will be put into operation by Starnav in 2015 on behalf of Brazilian oil giant Petrobras, will target fuel efficiencies as one of their primary aims. GE’s control system incorporates an innovative Energy Efficient mode, part of GE’s ecomagination portfolio. GE has developed a highly advanced predictive control algorithm which predicts future motion and updates the thrust demands if the vessel is calculated to move close to or outside the operator permitted area. This makes for fewer small, unnecessary corrections, thus reducing fuel consumption, emissions and equipment maintenance requirements. Additionally GE’s vessel automation and control system, featuring a novel fuel monitoring, recording and advisory system, grants operators greater insight into fuel consumption across various operational scenarios and cumulatively across the entire mission profile. ...

DNV GL recognised that E.R. Schiffahrt has retrofitted seven ultra large container vessels to meet the highest energy efficiency standards and improve its cargo capacity through the DNV GL Modification Excellence Award. Jörg Lampe, Senior Project Engineer Risk & Safety and Systems Engineering at DNV GL, presented the award to Jürgen Kudritzki, Technical Director at E.R. Schiffahrt, in Hamburg. The German shipping company is the first to receive this award. “E.R. Schiffahrt has made a sustained and intensive commitment to increasing the efficiency of its operations. Our analysis shows these ships use 15 per cent less energy – resulting in annual savings of approximately 3.8 Million USD”, said Jörg Lampe. E.R. Schiffahrt performed modifications on seven 13,100 TEU vessels – the eighth ship will be finished shortly. The changes include new bulbous bows, energy efficient propellers, engine modifications and cargo boosting. In addition to implementing the Route Specific Container Stowage notation (RSCS), the ships’ draft was increased by 0.5m – resulting in an increased deadweight of 7,591t, which is equivalent to 542 TEU at 14t for each of the vessels. DNV GL evaluated the vessels’ energy efficiency by using CFD calculation results, test reports and technical documentation to determine fuel ...

According to Poten & Partners, everyone in the tanker industry is aware of the recent drop in crude oil prices and the decline in bunker fuel prices that followed. Bunker fuel is the single most expensive cost in operating tankers, so this is a welcome relief for ship owners. The cost of Heavy Fuel Oil (HFO) in Fujairah has declined to a current price of $460 per metric ton from an average of $609/MT over the first six month of the year, a reduction of 24%. Due to the high oil prices over the last couple of years and the anticipation of continuing high prices in the future, owners have made operational adjustments by utilizing slow steaming on the ballast leg of a voyage, while shipyards and engine manufacturers have worked hard to improve the fuel efficiency of new ships. In this Weekly Opinion piece, we will examine the impact of these in the current fuel price environment. Using a VLCC as the basis for such analysis as the longer voyages benefit relatively more from fuel efficiency, we use a 2007 built VLCC ordered when HFO prices were around $160/MT and a modern 2013 built VLCC. Vessels can vary significantly ...

Ministers, Jung Hong-won and Alexander Stubb, highlighted a landmark 50th deal for the collaboration between Finland’s NAPA Group and Korea’s Daewoo Shipbuilding & Marine Engineering (DSME), as an illustration of the importance of the maritime industry to both nations.

Last year, Maersk Line owned and chartered fleet comprising 550 vessels completed about 37004 voyages called 33000 ports using 380 terminals in 117 countries. Given the sheer scope of Maersk Line’s operations, the Company is committed to reducing fuel consumption and CO2 emissions. This puts energy efficiency as one of the crucial objectives. That means taking careful steps towards optimizing these 37004 voyages in terms of energy efficiency. Wondering how do they go about ensuring the successful implementation of this endeavour? That’s where Maersk Line’s Global Voyage Centre (GVC) comes into the picture. The Global Voyage Centre hosts a giant screen that, monitors in real-time,  the position of all the Maersk Line owned and chartered vessels.  A team of senior seafarers monitors these vessels 24×7 and provides support to improve their energy performance and facilitate best practice sharing. “The Global Voyage Centre was setup as a project in July 2013 by selecting a few Captains and Senior Navigating Officers from the fleet join the team with an objective to bridge the communication gap between the shore staff and the fleet as well as monitor the vessels on long ocean passages on a real time basis. The GVC has since evolved to take on ...

With most ship owners switching to Marine Gas Oil inside designated Emission Control Areas as of January 1st 2015, the cost of fuel could rise by up to 50%, so all measures to reduce fuel consumption are vital. Research and field testing has shown that the latest developments in engine lubrication and unique marine energy management systems can add more than a 15% improvement in fuel efficiency, proving that even the smallest modification at the right time can add up to big savings. The pro’s and con’s of the three options for the shipping industry to comply with the new Sulphur Directive (1. Converting to Marine Gas Oil, 2. Installing an exhaust cleaning system onboard or 3. Retrofit to LNG usage) have been debated at large, but one consensus is that whichever method is chosen, there will be significant costs involved. Thomas Franck, past Chairman of the Finnish Shipowners’ Association, former CEO of Bore Ltd. and Board Member of Nanol Technologies says: “It’s a given that the majority of vessels that will travel in the new Emission Control Areas will switch from Heavy Fuel Oil to Marine Gas Oil, so identifying the most practical and cost effective way to operate within the ...

The Maritime Administration (MARAD) is testing state-of-the-art, environmentally efficient technology onboard the Training Ship (TS) Kennedy. The National Defense Reserve Fleet vessel was provided to the Massachusetts Maritime Academy by MARAD for Cadet training.  This one-year undertaking is part of a MARAD initiative to test fuel cells as a source of power for shipboard electrical systems.  Researchers will evaluate the performance of the fuel cell technology and how low sulfur marine diesel fuel can be used to efficiently power a fuel cell to produce auxiliary power.  Unlike using low sulfur fuel in diesel engine generators to provide electrical power, the system produces no harmful air emissions.
