A leader in its segment in terms of sustainability

Royal Niestern Sander developed and built a next-generation open top ice classed general cargo vessel. This type of vessel, dubbed ‘Easymax’, has a load capacity of 14,300 tonnes and a hold capacity of 625,000 cubic feet. The combination of that large load capacity and extremely low fuel consumption makes this type of vessel a leader in its segment in terms of sustainability.

The design challenge

The unique sustainable design of the Easymax was developed by Royal Niestern Sander in close cooperation with a number of carefully selected partners. The design of this vessel started with the requirements of a maximum hold volume, maximum deadweight and maximum fuel savings within the size limitations of the yard location. Also the vessel had to be easy to build and easy to operate: Easy Max. That required a lot of creativity and technical ingenuity of the engineering department of Niestern Sander.

To get straight to the point: in regard to loading and unloading, the Easymax truly is ‘easy to operate, maximum performance.

Easymax. The latest innovative type of vessel in the Wagenborg fleet. Easy to operate, maximum performance. A true leader in terms of sustainability.

Maximum dimensions

With a length of 149,95m and width of 15,90m, Easymax is the largest vessel ever built inner dike in the north of the Netherlands.

Maximum dimensions and load capacity

With a load capacity of 14,300 tonnes and a hold capacity of more than 625,000 cft, the Easymax is the biggest vessel ever built in the north of the Netherlands on the landward side of the dikes. With a length of 149.95m, a beam of 15.90m and a draught of 8.60m, the Easymax has the maximum possible dimensions for the Royal Niestern Sander shipyard. With two large box-shaped holds – 13.50m wide, 12.10m high, and 47.36 and 64.38m long, respectively – the Easymax excels in her class with her very high intake for heavy or light cargo, timber and paper and project cargo. The Easymax is suitable for worldwide commercial operations, including in such areas as the Baltic, the North Sea, the Mediterranean, the St Lawrence Seaway, the Panama Canal and the Suez Canal.

Sustainable vessel with low fuel consumption

With the Easymax, Niestern Sander designed a relatively large vessel in terms of cargo intake and hold capacity but without any major increase in overall dimensions or tonnage. In addition, the combination of the 2.999 kW MAK 6M32C main engine, gearbox, propeller and thruster means that the Easymax has an energy-efficient propulsion system, leading to extremely low fuel consumption. The hull shape has also been optimized for various different draughts, resulting in an ultra-low Energy Efficiency Design Index (EEDI).

I must say that this vessel truly is built for easy operation.

Sustainable ship design

Unlike the great majority of many general cargo vessels, the Easymax has her bridge and accommodation positioned in front of the ship. One of the principles for her design was to have maximum dimensions and capacity in two box-shaped holds. Positioning the accommodation in the fore part of the ship – where much of the shape is located that is needed for low fuel consumption – creates greater hold volume in the aft section and on deck. It also reduces the overall tonnage. Another advantage is that there are no line-of-sight restrictions as regards deck cargo and project cargo. As a result, the accommodation of the vessel can be situated a deck lower. Yet another advantage is that the centre of gravity is lowered. This improves the stability of Easymax and hence her load capacity. Finally, the lower accommodation construction creates an aerodynamic shape with lower resistance. This results in reduced fuel consumption of this sustainable ship.

Optimal load out

The hallways of Niestern Sander are optimal situated for the production process. After constructing a block section, this section can be transported outside and positioned next to the water.

Transport on site

Often transport of heavy block section is performed with trailers.

Bridge

Construction of the bridge in progress: already painted.

Front section

The front section of the Easymax vessel is using the maximum possibilities of the construction hallway in terms of dimensions.

Launch

After months of ship building, finally yard number 848 was launched.

Hold capacity

Easymax has maximum hold capacity within the yard dimensions. With a total of two holds, 625.000 cft is reached.

Propellor in a nozzle

The largest vessel ever built in the north of the Netherlands has a humble main engine with an installed capacity of only 2.999 kW.

Section turning

Sections are often turned inside the construction hall during the production process for outfitting purposes.

Easy to build and operate

The design of the Easymax means that there is only a limited amount of equipment in the holds. For example, there are no tween decks, container fittings, securing eyes or girders in the hatch package. For most bulk cargoes these options are unnecessary. There are, however, separation bulkheads, dehumidifiers, and hold lighting. The bottom line is a cheaper and lighter vessel that is easy to operate and maintain.

Comfort on board and remote support

A high standard of comfort for the crew is also an important principle of the design. Positioning the accommodation in the fore part of the Easymax and the engine room aft means that the noise level in the modern cabins is very low. In the working areas of the Easymax for the crew, special attention was paid to ergonomics, safety, technology and layout. Good examples are the AlphaBridge, with its 360° view and the hold entrance in the area between the two holds. The ship has a good satellite connection for onboard TV and Internet. This allows the crew to communicate with their people back home. Moreover, the internet connection allows equipment and systems to be read remotely from shore for maintenance and support.
