European owners want shipping back in COP21 text

European shipowners have joined the European Commission, Members of the European Pariament and various stakeholders in calling for shipping to be put back into the text.

The International Chamber of Shipping says it would be helpful for the new agreement to reiterate the vital role of the UN International Maritime Organization in the development of further measures to reduce shipping’s CO2 emissions. This would give extra encouragement to build on the global regulations IMO has already successfully adopted and which should reduce CO2 per tonne-km 50% by 2050.

However, says ICS, the absence of text is unlikely to inhibit the aspirations of governments – which are shared by the industry – for IMO to take further action.

“While text on shipping could be useful, the negotiators are now having to focus on the really high level things like climate finance to ensure the overall agreement is a success which is what everyone wants” said ICS Secretary General, Peter Hinchliffe.

ECSA Secretary General Patrick Verhoeven called the talks in Paris “a unique opportunity” to signal IMO member states to act decisively in order to further regulate CO2 emissions from ships on a global level.

“It would provide support for their ability to move forward and give new impetus to ongoing discussions, which we hope will very soon reach fruition,” said Mr. Verhoeven.

ECSA says that though the IMO has already made strides when it comes to the shipping industry’s carbon footprint, its work on CO2 emissions reduction is far from completed. It remains firmly on its agenda and will be considered again at the next meeting of the IMO Marine Environment Protection Committee in April 2016.

ECSA says the shipping industry supports the establishment, as soon as possible, of a mandatory system of data collection from individual vessels, understanding that the possibility of further market based measures might be revisited after an IMO analysis of the data submitted by ships.

“We firmly believe that deleting any reference to shipping and the progress needed at IMO level is a missed opportunity. The EU has already placed its faith in the IMO process by adopting legislation that will enable and support IMO in establishing a global data collection scheme,” said Mr Verhoeven.”An irreversible process leading to lower CO2 emissions from ships has started. Efforts at IMO and EU level can only be bolstered by a clear signal from the highest UN instance on climate change. We sincerely hope that negotiating parties will seriously reconsider and heed our call for shipping to be reintroduced in the final climate agreement.”

Innovation agency backs Royston research project

The support for the £1.5 million project, which is being conducted in collaboration with Newcastle University’s School of Marine Science & Technology, is coming from Innovate UK, the U.K.’s government sponsored innovation agency

The project is focused on producing a system for the complete understanding of the complex energy flows around a vessel.

Energy use and consumption on vessels will be measured through a physical monitoring system integrated with dedicated software and the development of new products and services to aid vessel efficiency.

The three-year project will initially focus on developing a system examining total energy flows and vessel energy architecture for smaller vessels, then for progressively larger vessels provided by maritime and shipping companies Svitzer, Topaz and CalMac Ferries, who are collaborative partners on the project.

The ultimate goal is to reduce the environmental impact of shipping and maritime activities, such as the reduction of CO2 emissions and poisonous air pollutants both when the vessel is at sea, and mitigating the effect on near-by communities when the vessel is in port.

The system will also focus on the prevention of catastrophic faults and failures through early warning diagnostics. It is predicted that the proposed whole-vessel system will generate considerable financial reward to end-users from efficiency savings and reduced “port dues” for ships demonstrating compliance towards reduced energy consumption.

Lawrence Brown, Managing Director of Royston Diesel Power, said: “We are delighted that Royston’s reputation as innovators in marine engineering has been recognized by the award of this grant by Innovate UK to help us develop our marine offering.

“The Managing Energy on Marine Vessels program is ambitious and challenging as the performance of one system within a vessel is under the influence of many other interconnected systems, all of which effect the whole-vessel energy usage.

“The project will push boundaries and allow us to develop new methodologies and technologies. The collaboration with Newcastle University is particularly important from a research standpoint and allows the project to benefit the wider marine and academic community as a whole.

“For Royston, we hope that this project will bring an excellent return on investment and added value to the company and our suppliers from significantly increased sales in the UK, Europe and elsewhere.”

World’s greenest cruise ship to be unveiled at COP21

 

That’s the hope of the Japan based Peace Boat, an NGO that has Special Consultative Status with the Economic and Social Council of the UN and serves as an official messenger for projects including the UNISDR Resilient Cities Campaign.

Nominated for the Nobel Peace Prize in 2008, Peace Boat’s main means of taking its message to the world is through its ship, currently the chartered in Ocean Dream (which was delivered in 1982 as Carnival Cruise Line’s first newbuild, the Tropicale).

Since its establishment in 1983, and using a variety of ships,  Peace Boat has organized over 80 voyages, carrying more than 50,000 people to over 180 ports.

Now, though, Peace Boat has scheduled a briefing that will be held December 5 in Paris during the COP21 conference. It will reveal more details of the design for its Ecoship, which it says will be the  world’s “greenest” cruise ship, along with its plans for the ship’s maiden voyage in 2020.

The plans for the future-ready 55,000 ton Ecoship have been developed by a team of over 30 engineers, scientists and thinkers from the fields of shipbuilding and  eco-technology (including renewable energy, architecture, and waste management).

With a hull form inspired by the whale, the vessel’s ecologically friendly features include 10 retractable solar-paneled sails and retractable wind generators, as well as a future-ready hybrid engine.

Peace Boat says that with its energy efficiency and projected cuts in CO2 emissions its Ecoship will be the flagship for green technology in passenger shipping, serving as a model for cruise operators worldwide.

“Peace Boat’s 2020 launch of the Ecoship offers a vision for a climate-friendly future and can lead the way towards a green cruising model that can also impact the wider shipping industry. The industry must adapt to the planet’s needs,” says Yoshioka Tatsuya, Founder and Director of Peace Boat.

“We are delighted to see wind propulsion being used on this innovative cruise ship design. The Ecoship will be a front runner in the design of lower impact cruise vessels and we will be working with the industry segment to help bring more wind propulsion solutions into the mix,” says Gavin Allwright, Secretary of the International Windship Association (IWSA), “IWSA has recently welcomed Peace Boat onboard as one of our newest members, and we look forward to working together over the coming years, helping to spread the message of low carbon, sustainable shipping worldwide.”

Finnish owner orders first LNG-fueled handysize bulkers

ESL Shipping and Swedish steel company SSAB have signed a long-term frame agreement covering SSAB’s inbound raw material sea transports within the Baltic Sea and from the North Sea. The purpose of the agreement is to enable mutual, long-term gains in efficiency and to reduce overall logistics costs, while simultaneously making raw material logistics as sustainable and environmentally friendly as possible. At present, the aggregated sea transport volume covered by the agreement is estimated to be 6–7 million tons annually.

 

The two ice-class 1A ships being built as a result of the agreement will be the first LNG-fueled large bulk carriers in the world. CO2 emissions per ton of cargo transported will be reduced by more than 50% in comparison to present vessels.

“This new agreement is a solid example of SSAB’s sustainability strategy in action,” says Per Bondemark, Chief Procurement Officer at SSAB.

“ESL Shipping’s new customer agreement running for several years will secure growing freight volumes, and the new investments to be implemented will release old vessel stock for other transport needs. Besides their environmental benefits, the cost savings provided by the new technology will also allow better profitability,” says Aki Ojanen, Chairman of the Board of ESL Shipping and CEO of its parent Aspo Group.

The two new vessels will be built at the Qingshan Shipyard of Sinotrans & CSC SBICO in China and will start operating in the Baltic
in early 2018. The total value of the investment is approximately EUR 60 million. The investment cash flow will be divided progressively between 2015 and 2018.

ESL Shipping has worked in close cooperation with Finnish designer Deltamarin on the ship design and the ships have been tailored to customer needs with special attention given to the efficiency of cargo handling and cargo hold arrangements.

Deltamarin has performed the full concept and contract design of the ships for ESL and has a contract with the shipbuilder covering basic and detail design, procurement handling and site assistance for the two vessels based on Deltamarin’s B.Delta26LNG design.

The LNG-fueled B.Delta26LNG bulk carrier is equipped with both dual-fuel main and auxiliary machinery. The ship has a type C LNG tank of approximately 400 cu.m capacity.

The B.Delta26LNG also exhibits very efficient operation in ice class conditions, far surpassing any other similar ships trading in such conditions. Extensive model tests have been performed for both open water, at SSPA in Sweden, and Ice Class 1A operations, at Aker Arctic Technology in Finland.

The vessels will be classified according to DNV GL rules.

The B.Delta26LNG has a shallow draft of max. 10 m, length overall of 160 m, breadth of 26 m and maximum capacity of 25,600 tonnes deadweight.

Alfa Laval EGR economizer is a fuel saver

For many shipowners, it could make EGR —rather than SCR (selective catalytic reduction) — the optimum means of meeting the NOX reduction requirements set by EPA Tier 4 and IMO Tier III requirements.

Developed by Alfa Laval in close cooperation with MAN Diesel & Turbo, the Aalborg EGR-HPE is a revolutionary new economizer enclosed in a pressure casing. Placed in-line ahead of the pre-scrubber sprayers in the EGR circuit, it can be used to gain a number of advantages. If connected to a conventional waste heat recovery system, for example, waste heat recovery becomes substantially more efficient – and is possible at significantly lower engine loads.

“EGR provides Tier III NOx compliance with a very compact footprint, but compliance itself is only part of the full potential,” says John Pedersen, Business Manager, Boilers, Combustion & Heaters at Alfa Laval. “Working closely with MAN Diesel & Turbo to optimize the EGR technology, we saw additional opportunities through our expertise in marine boilers. The result is the Alfa Laval Aalborg EGR-HPE economizer, which paves the way for extraordinary energy and fuel savings.”

“By moving the break point for waste heat recovery from a medium engine load down to a low load, the Aalborg EGR-HPE enables even slower steaming,” says Mr. Pedersen. “That means fuel savings that quickly pay back the economizer, offset the EGR investment and lower CO2 emissions on top of the NOx reduction.”

The source of all these benefits: the heat that would otherwise be lost during EGR. In the EGR process, around 30% of the exhaust gas is directed back into the engine, reducing the combustion temperature and thus the production of NOx. However, as only the 70% of the gas now reaches the traditional exhaust gas boiler after the turbocharger, waste heat recovery is reduced by 30%.

However, the Aalborg EGR-HPE is placed in-line before the EGR pre-scrubber spray jets that cool the exhaust gas. The economizer  thus has access to much higher temperatures than traditional exhaust gas boilers. So, while the installation is light, compact and self-cleaning due to the high speed of gas flow, its application potential is enormous. This can be seen in the way it increases the efficiency of a conventional waste heat recovery system.

The Aalborg EGR-HPE is integrated with conventional waste heat recovery after the turbocharger by means of its steam drum, which is shared by the traditional exhaust gas boiler. With the output of the traditional economizer feeding into the shared drum, the Aalborg EGR-HPE produces extremely high-quality steam with a temperature of just above 400°C, bringing the waste heat recovery system to a much higher level of efficiency.

“The difference in steam quality has a direct effect on the performance of the steam turbine,” says Mr. Pedersen. “Installation factors play a role, but a substantial increase in power generation can be expected.”

Fuel savings through even slower steaming

Even more importantly, using the Aalborg EGR-HPE in an integrated system allows waste heat recovery to occur at lower main engine loads than possible with a traditional waste heat recovery system in Tier III operation. In other words, it creates the possibility for even slower steaming.

“The EGR economizer makes waste heat recovery beneficial at far lower engine loads, down to around 30%” says Mr. Pedersen. “This means that vessels can steam even slower, with huge fuel savings as a result. A vessel performing EGR and using the Aalborg EGR-HPE will be not only compliant with Tier III, but also substantially more fuel efficient.”

Proven results at sea

The savings with the Aalborg EGR-HPE are not merely theoretical.

In a project supported by the Danish Energy-Technological Development and Demonstration Program (EUDP) and developed in cooperation with Aalborg University, the EGR boiler has been rigorously tested aboard the Maersk Cardiff, a 4,500 TEU containership delivered to Maersk Line in 2013.

“As a front-runner in the pursuit of green technologies, we were keen to see what the Aalborg EGR-HPE could do,” says Ole Christensen, Senior Machinery Specialist at A.P. Moller-Maersk. “But while we were enthusiastic about the boiler’s potential, we were also somewhat uncertain as how it would handle the physical realities of EGR. The temperatures are twice as high as those of traditional waste heat recovery, and the gas pressures are far greater.”

Those concerns disappeared when the boiler was brought online with the Maersk Cardiff’s two-stroke MAN B&W 6S80ME-C9 engine in November 2014. “Not only did the boiler survive,” says Mr. Christensen, “the results we have seen during testing are very promising.”

“By introducing the EGR boiler into the NOx equation, we’ve truly changed the balance,” says Alfa Laval’s Pedersen. “Suddenly EGR is not only a means of Tier III compliance, but also a means of radically improving the vessel’s energy efficiency. And that makes it a very different sort of investment.”

Euro MPs want to fast track setting of shipping GHG target

 

Specifically, the resolution “calls for all the Parties to work through the International Civil Aviation Organization (ICAO) and the International Maritime Organization (IMO) to develop a global policy framework to enable an effective response, and to take measures to set adequate targets before the end of 2016 for achieving the necessary reductions in the light of the 2 °C target [for a limit on global warming].”

The resolution has drawn a very guarded response from European shipowners.

“We are happy to see that the European Parliament recognizes the importance of a global solution for international shipping and gives a vote of confidence to the IMO, which should be allowed to pursue its efforts,” said Patrick Verhoeven, Secretary General of ECSA, the European Community Shipowners Association. “We are however also concerned by the deadline adopted by MEPs on Wednesday. 2016 is right around the corner and as such it is rather unrealistic to expect the IMO to come up with a solution in a matter of months. A unilateral European push for a hard deadline may be counterproductive.”

ECSA calls IMO’s track record in developing technical CO2 energy efficiency measures for the maritime sector “impressive.”

Following the adoption of the amendments to MARPOL Annex VI, which came into force worldwide in 2011 and which now apply to about 95% of the global merchant fleet, international shipping is the only industrial sector already covered by mandatory and binding global measures, notes ECSA. IMO also recently adopted the Energy Efficiency Design Index (EEDI), which requires all ships constructed after 2025 to be 30% more efficient that those built in the 2000s, with further efficiency improvements going forward. Finally, the shipping industry itself, prompted by an increase in bunker prices, has made strides in increasing its energy efficiency and curbing its CO2 emissions.

As a result of recent efforts, the contribution of shipping to global CO2 emissions has in fact dropped, says ECSA.

According to the latest IMO Green House Gas study, published in 2014, international shipping (while transporting about 90% of world trade) produces about 2.2% of the world’s total CO2 emissions. This figure was 2.8% in 2007, and the total CO2 emissions from shipping went down by over 10% between 2007 and 2012. This was despite continuing growth in maritime trade which means that shipping is already delivering carbon neutral growth.

“The 2016 deadline is not consistent with the steps already taken at EU level” commented Benoit Loicq, ECSA Safety and Environment Director. “By pushing for an extremely tight deadline, the EU would essentially undermine the IMO procedure. If the EU would then focus on regional measures, it would be backtracking on its own policy.”

ECSA says the EU Monitoring, Reporting and Verification (MRV) Regulation is intended to be the first phase of a stepwise approach geared towards a global (read IMO) solution by allowing to determine the real contribution of shipping to global CO2 emissions.

“The course of action that has been agreed is to start with an accurate picture of the shipping industry’s CO2 emissions in 2018 (i.e. two years after the MEP-backed deadline),” says Mr. Loicq. “If we now backtrack and skip the data collection phase altogether, how would it be possible to set realistic and fair targets?”

ME-GI for first Crowley ConRo passes milestone test

The engine is the first of two 8S70ME-C8.2-GI units for delivery to VT Halter Marine, Pascagoula, MS, for installation in the two 2,400 TEU ConRo ships it is building for Crowley Maritime Corporation.

The vessels will be two of the world’s first LNG-powered ConRo ships, with container Lift-on/Lift-off (LO/LO) and vehicle Roll-on/Roll-off (RO/RO) loading. Designed to travel at speeds up to 22 knots, they will be 219.5 m long, 32.3 m wide and have a deep draft of 10 m. In addition to carrying 2,400 TEU of containers they will be able to carry nearly 400 vehicles in an enclosed Roll-on/Roll-off garage.

Crowley ordered the ME-GI engines, along with three MAN 9L28/32DF auxiliary engines for each vessel, in early-2014. The company selected the high-pressure, Diesel-cycle ME-GI engines because of their high efficiency and power concentration. The ME-GI’s ability to avoid derating, and its negligible methane slip, also contributed to its selection.

Crowley reports that the newbuildings will reduce the amount of CO2 emissions attributable to each container by approximately 38%.

The ships will meet or exceed all regulatory requirements and will have the CLEAN notation, which requires limitation of operational emissions and discharges, as well as the Green Passport, both issued by DNV GL.

The ME-GI engine

The ME-GI engine is the culmination of many years’ work, and gives shipowners and operators the option of utilizing fuel or gas depending on relative price and availability, as well as environmental considerations.

The ME-GI uses high-pressure gas injection that allows it to maintain the numerous positive attributes of MAN B&W low-speed engines that have made them the default choice of the maritime community. The ME-GI is not affected by the multiple de-ratings, fuel-quality adjustments or large methane-slip issues that have been seen with other dual-fuel solutions.

MAN Diesel & Turbo sees significant opportunities ahead for gas-fueled tonnage as fuel prices rise and exhaust emission limits tighten. Research indicates that the ME-GI engine delivers significant reductions in CO2, NOx and SOx emissions. Its negligible methane slip makes it even more environmentally friendly

An ME-LGI counterpart that uses LPG, methanol and other liquid gases is also available, and has already been ordered.
