This June the Finnish based Eniram company from Helsinki, was selected as a finalist of an award for emerging European technology companies Eniram provide a number of products for on board and ashore monitoring of ship performance offering real time solutions. A product gaining wider acceptance for owners and operators of cruise ships, large freight vessels and tankers is their Dynamic Trimming Assistant (DTA). A number of data sensors, with software analyzing the ship’s trim, helps vessel crews optimize trim at all times, by presenting the solution in an easy to understand graphical display. DTA does this by balancing inter related variables such as minimizing water resistance, decreasing fuel consumption, use of stabilizers and reducing emissions. External items such as waves, wind and speed are also included in the analysis. In practice, this means startling savings may be achieved. Several fleet operators are using DTA including Royal Caribbean Lines and the Hamburg Sud Group. A separate but not unrelated product, is Hull Fouling Analysis used to optimize the maintenance and efficient operation of the submerged ship’s hull area.

The European Tech Tour Association is an independent non-profit organization committed to the development of emerging European technology companies covering a wide number of applications. This June the Finnish based Eniram company from Helsinki was selected to be one of 30 finalists.

External items such as waves, wind and speed are also included in the analysis.

In practice, this means startling savings may be achieved. Several fleet operators are using DTA including the Oasis of the Seas and six other Royal Caribbean ships. Following a test period on the 5,500 TEU container ship Alianca Maua, where fuel savings of between three to five per cent were reported, the Hamburg Sud Group announced in April that 26 vessels are to be equipped with DTA.

A separate but not unrelated product, is Hull Fouling Analysis used to optimize the maintenance and efficient operation of the submerged ship’s hull area. Monitoring draft variations and the effect of changes in the hull, it provides a means to optimize the cleaning costs and keep fuel waste due to fouling to a minimum.
