Fuel Savings

Maersk Tanker Fleet on Fuel-saving Retrofit Crusade

Maersk Tankers plan to spend up to $35m as it pushes ahead with a fuel saving retrofit programme. One of the company's "I-class" VLCCs is being fitted with fuel saving devices, iincluding Becker Mewis propeller ducts and propeller boss cap fins on a range of owned tankers. The programme includes screening and retrofitting around 70 tankers over the next two to three years, reports Carbon Positive. The company's drive to raise fuel efficiency will focus on as many as 35 separate measures, which will all potentially contribute to fuel savings across the fleet. The company believes that retrofitted tonnage could yield fuel savings of as much as 8-10%. Company naval architects will carefully assess each class of vessel in the company's fleet and specialists from the group's technology firm, Maersk Maritime Technology, to determine which retrofits would be the most effective. Maersk's view is that existing vessels can give fuel savings of between 8 – 10% at a relatively low cost, rather than ordering new ships against the current backdrop of substantial overcapacity. Cutting fuel consumption by 8% would translate into savings of around $8,000 a day, or $30 million per year, for each VLCC. Source: Carbon Positive

Navy Stern Flap Installations for Fuel Savings

060914-N-4856C-005_web.jpg

The U.S. Navy began installing stern flaps in April on amphibious ships in an effort make ships more fuel efficient and save up to $450,000 in fuel costs per ship annually. USS Whidbey Island (LSD 41), the first dock landing ship to receive stern flaps, began the installation process mid-April during a scheduled maintenance availability in Norfolk, Va. The ship is expected to head back to sea in late November. "A stern flap, located on the aft end of a ship

Alfa Laval EGR-HPE Economizer a Boon

Alfa Laval PureNOx approved for MAN Diesel & Turbo EGR system

  With Tier III NOx limits entering into force in North America and the US Caribbean in January 2016, the time has come for many ship owners to choose their method of compliance. Exhaust Gas Recirculation (EGR) on MAN B&W engines has strong advantages on its own. But combined with a new pressurized EGR economizer from Alfa Laval, it also offers the potential for massive fuel savings. “EGR provides Tier III NOx compliance with a very compact footprint
