Havyard Bags Hybrid Battery-Powered Arctic PSV

first_imghavyard, April 15, 2014 zoom Havyard Group AS and Fafnir Offshore have signed a $56.6 million contract for the construction of Havyard 833 WE ICE platform supply vessel.The vessel, designed by Havyard Design and Solutions in Fosnavaag, will be constructed at Havyard Ship Technology`s yard in Leirvik in Sogn, Norway. The vessel will become newbuild number 126 and is slated for delivery in July 2015.Havyard 833 WE ICE is a newly developed platform supply vessel (PSV) design based on the most recent technology within fuel economy and environmental friendliness. This PSV is designed to operate as efficiently as possible and with the least amount of influence from exposed waters.The greatest innovation onboard the vessel is that it is equipped with a hybrid battery powered diesel-electric propulsion system.“When we develop a new ship design we have two main focal points,” said Arve Helsem Leine, Design Manager of Havyard Design & Solutions. “Those are the customer’s demands in relation to the ship’s operational needs and area of operation and also to use the latest accessible technology and research tools in order to make the ship as efficient as possible. We have invested a lot in our design philosophy and in our calculation tools and methods for testing. We also work closely with key suppliers in developing good solutions for our designs and hybrid battery power is a good example of this.”Efficient energy when neededThe idea of hybrid battery diesel-electric propulsion system is the same as for hybrid cars, namely to produce energy as efficiently as possible while also having access to necessary power whenever it is needed.A typical PSV has large variations within its energy needs depending on the operation being carried out. Weather and wind conditions, waves and currents, also play their part in the swift variations of energy requirements.“In traditional diesel-electric propulsion systems the diesel generators` load will vary according to the alternating energy needs,” said Design Manager Leine. “This means that diesel engines cannot constantly operate within a load area where these engines have the lowest possible fuel consumption.”“With hybrid battery power you can constantly operate diesel generators at an optimal level. When energy demands vary you can either charge or discharge batteries, depending on whether the energy demands are lower or higher than the capacity of diesel generators in operation. Response time in relation to variation in power demands is also a lot shorter, so there is a quicker transfer of power to the ship`s thrusters which ensures a more precise and secure positioning, for example in operations by an offshore rig.”“The hybrid system for this ship is developed in close cooperation with Norwegian Electric Systems and shows exactly how important cooperation within the value chain is, in order to bring forth the best products. This hull design combined with hybrid battery power ensure that a PSV in given operations uses 30 to 40% less fuel compared to a traditional PSV,” said the Design Manager.This latest contract is the second Havyard has signed with the Icelandic offshore shipping company Fafnir Offshore. On April 4th the hull of Havyard`s newbuild 120, Fafnir’s first newbuild, arrived the Leirvik shipyard in Sogn, Norway.“Havyard 833 WE ICE design, designed to operate in the Arctic region, with its hybrid battery power allows us to save even more on fuel expenses. Havyard really does live up to its vision ‘Improving life at sea’ and we have great faith in the future and our cooperation with Havyard. That’s why we have also secured an option for construction of a sister ship to be delivered during the fourth quarter of 2015 and we strongly believe we will take advantage of this option,” said Mr. Erlingsson CEO of Fafnir Offshore.“Havyard Group is a ship technology group with focus on developing competitive products and systems, based on competence of and having control of the value chain,” says CEO Geir Johan Bakke of Havyard Group. “Our greatest asset is quality products and services adding value to the customer. Our business model with products in ship design, equipment and shipbuilding, provide us with flexibility when we offer exactly what the customer wants, whether the customer wishes to construct in Norway or internationally“.Key data for Havyard 833 WE ICE PSV:Length: 89.7 mBreadth: 19.6 mSpeed: 15 knotsDeck area: 1000 m2Crew: 25 personsDead weight: 4250 tonneslast_img

TransAlta Corp timed power outages to drive up prices Alberta Utilities Commission

CALGARY — TransAlta Corp. deliberately timed outages at power plants in Alberta at peak times in order to drive up electricity prices, the province’s utilities commission said in a ruling Monday.The Alberta Utilities Commission conducted hearings after the province’s market surveillance administrator alleged that the Calgary-based company manipulated the electricity market by shutting down coal-fired power plants in late 2010 and early 2011 to drive up power costs during periods when demand was high.“The commission concludes, based upon clear, cogent and convincing evidence that TransAlta could have deferred each of the above described outages to off peak hours but chose instead to take them during peak or super-peak hours so as to maximize the benefit to its own portfolio,” the commission said in its decision.“In other words, the timing of the outage was determined by market conditions rather than by the need to safeguard life, property or the environment.”The timing of the outage was determined by market conditions rather than by the need to safeguard life, property or the environmentThe commission also found that TransAlta breached a regulation by allowing its energy trader Nathan Kaiser to use privileged information related to plant shutdowns so that the company could benefit in the market.“TransAlta knew, or should have reasonably known that Kaiser had information regarding the capability of Sundance 1 and 2 to produce electricity that could reasonably be expected to have a material impact on market prices and would give him an advantage over market participants who did not have that information,” the commission found.But the commission said Kaiser established a defence of due diligence based on repeated assurances from senior TransAlta management that he could direct trades despite possessing information that wasn’t public.The commission also found that the market surveillance administrator did not prove allegations that TransAlta’s compliance policies, practices and oversight were inadequate and deficient.TransAlta Corp buys solar and wind projects in U.S. for US$75.8 millionCoal-fired power plants feel the heat of Alberta’s new carbon tax rulesTransAlta Corp cutting 20% of workforce in Canadian coal unitTransAlta’s shares fell to $8.40 at 10:31 a.m. in Toronto, the lowest since the stock debuted in 1992. The S&P 500 Utilities Index was down 0.5 per cent.TransAlta’s credit rating may be at risk if it’s hit with a penalty, Ben Pham, an analyst with BMO Capital Markets, wrote in a note Tuesday. The company has enough liquidity to cover the cost of a fine, which probably won’t affect TransAlta’s dividend, he said.In a release late Monday, TransAlta said it has received the decision and will be reviewing the ruling.It said its response could “include the possibility of an appeal to the Alberta Court of Appeal.”The company has previously denied all of the allegations, calling them “categorically false” and saying that it triggers outages for maintenance, operations and safety purposes.The commission said it will resume proceedings later to determine how much TransAlta benefited from the closures and what penalties to impose against the company.Jim Law, a spokesman for the commission, said it could fine up to $1 million per day per offence, plus claw back any benefits if it finds TransAlta gained from any offences.Brad Hartle, press secretary to Alberta Energy Minister Margaret McCuaig-Boyd, said in a statement that the government is “very concerned” that TransAlta was found to be breaking the rules.“Alberta families need to know that they can get the power they need at a reasonable price,” said Hartle. “When the process is complete, we will take a good look at what happened, as well as what has happened since to determine whether there are steps our government should take to better protect consumers.”With a file from Bloomberg read more
