New 300hp (224 kW) Diesel Outboard

At the recent international defence exhibition (DSEi) in London, a new lightweight diesel engine was on display from Cox Powertrain developed with Ricardo UK. The power dense of 300hp (224 kW)/4,000rpm is a 3.6 liter supercharged 2-stroke diesel engine, weighing 136 kg. The four cylinder, eight piston engine module features an opposed piston (OP) configuration and uses a Scotch Yoke cranking, saving weight and moving parts. A two module variant will produce 700+hp. Some variants may be able to deliver up to 900 hp. Beta testing will commence in 2014 with an estimated launch date for the outboard motor version in 2016. [More]

Fleet in service – exploit its potential, control costs: Fuel Saving with Trim Optimization

The maritime-shipping industry has also been forced to contend with the key issues of energy efficiency and sustainability. Optimizing the trim of a ship is a good way to achieve lasting reductions in fuel consumption. In fact, trim optimization has been an object of investigation since the 1990s. Back then, forward-thinking German shipowners were using models in towing tests designed to determine the trim that produced the lowest resistance as a ship moved through water. These tests showed that in many cases a slightly lower forward draft yielded the ideal trim. Based on these findings, INTERSCHALT added a ballast optimization tool to its MACS3 loading computer system. However, over the next 15 years interest in this special module declined because the costs for conducting the associated towing tests proved to be too high. Significant fuel saving by trim optimization "Determining the optimum trim is one thing; being able to practically apply these findings in actual ship operation is... [More]

Damen Shiprepair & Conversion has developed a new innovative product, the ‘Quick Docking/Fuel Saving’ package. This offers owners a fast and low-cost additional docking with the sole aim of reducing fuel consumption in between the five-year statutory survey period. The first vessel booked under the new concept has docked at Damen Shiprepair Brest (France). It is the capesize bulker ‘Castillo De Catoira’ operated by Spanish company Empresa Naviera Elcano. Damen expects to bring more of its vessels to its ship repair yards. Jos Goris, Managing Director of Damen Shiprepair Brest and initiator of the concept, comments: “We know that hull resistance builds up during years of service and this can have a significant impact on performance and consequently, fuel costs. By introducing this product, we are thinking along with our customers and know that fuel costs are a major consideration for shipowners and charterers, especially in this economic climate.”...

On third of September the second inland navigation tanker, which is also powered by natural gas, has been christened by the President of the Central Commission for the Navigation of the Rhine, Ms Belliard, in Rotterdam. The launch of the GreenRhine tanker took place at the Port of Rotterdam in the presence of representatives from the Dutch and European inland navigation sectors, local and regional authorities, suppliers, Interstream Barging (from whom Shell has chartered the ship) and Peters Shipyards, the company that built the ship. The sister ship GREENSTREAM is absolutely equivalent to the newbuild GREEN RHINE The GreenRhine is the second of two gas-electrically inland navigation tankers that Shell is chartering for the transport of mineral products on the Rhine. The GreenRhine is absolutely equal to the first natural gas powered vessel Greenstream. They feature many innovations in the fields of safety and energy efficiency. For example, rather than a single large engine like trad... [More]

Flow-optimized propellers can reduce fuel consumption by up to ten tons per day To improve ships manoeuvrability and energy efficiency also the propellers play a big role. Worldwide leading manufacturer of ship propellers is the Metallguss GmbH (MMG) in Waren, Germany. The company produces also propellers with six blades with a diameter of up to 9,30 meters and a weight of 97 tons for example for container ships with a load capacity of 9.400 TEUs. The propulsion power of such 286 meters long and 48.20 meters ship with a draft of 14.50 meters is of one diesel engine with an output of max 52.290 kW. With this a speed of 22.3 kn is reached. Propellers of the "AIDAstella" have a diameter of 5.2 meters and weigh each 12.8 tons The propeller is pretty much decisive to transfer as much as possible of the engine energy into propulsion energy. With particular large diameters and very specific blade geometry an efficiency gain of three to four percent can be reached – with following posit... [More]

Fleet in service – exploit its potential, control costs: Increase of load draft

By Peter Pospiech at September 10, 2013 07:16

Vessels of the today’s fleet in service may be modified by increasing the load draft to improve the capacity. This results in a more efficient ships operation that is particularly worth at slow steaming and with heavy container loads. The plimsoll line If load draft and load capacity are increased at unchanged ships power the energy consumption per ton load is reduced – and causes therefore a better efficiency. For this only the plimsoll line must be changed. This relatively simple process can be done easily during the next survey and / or often during normal operation. At vessels with ice-class it’s important to consider that an increase of load draft normally comes to a downgrading or even a nullity of the mentioned ice-class for the new load draft. Before an implementation takes place the procedure of a feasibility study is highly recommendable to ensure that the load draft of the affected ship really can be increased. With this, the hull stability for the increas... [More]

Universal oils are not unrestricted usable

At slow steaming cold corrosion can occur – Castrol sees concerns by specifications given from the engine manufacturers confirmed. Many shipping owners go for slow steaming. But to avoid long term damages by slow steaming particular adjustments must be done. One aspect is the use of optimized lubricating oils. A possible problem is cold corrosion. The lubricating oil manufacturer, e.g., Castrol Marine assumes that, during slow steaming, cold corrosion can happen if lube oils with lower base numbers (BN) come together with fuels with higher sulphur content. “We always point out that oils with lower BN are unsuitable for slow steaming with modern diesel engines. Both market leading OEM’s have now created specific guide lines, which go along with our experiences”, says Castrol manager Paul Harrold. They recommend their customers to coordinate the use of lube oils with engine type and working conditions. Last May Castrol presented some case studies. These figures un... [More]
