iStow loading software completes integration with DNV’s Eco Assistant
OCTOBER 13, 2021

Indonesian start-up Pranala Digital Transmaritim has integrated its loading software iStow with trim optimisation software Eco Assistant (EA) from DNV.

The integrated solution has been installed onboard the Sei Pakning at SMI Shipyard in Cilegon, Indonesia to improve stowage planning and fuel efficiency. Stowage planning is instrumental for a ship’s safety and ensures IMO stability criteria is met. A ship’s shear forces and bending moments must be ensured to reside within the allowable boundaries. In order to meet tight ship operations, all stability and longitudinal strength calculations and standard document generations could be accomplished in almost no time by loading software.

In operations, a ship sails in fully, partly loaded, or in ballast conditions. The ship is often in a trim condition. From the hydrodynamic perspectives, most ships have less resistance in a certain trim conditions, meaning the ship consumes less fuel in that condition. EA, developed by DNV, seeks an optimum trim condition at which the ship consumes less fuel.

The optimum trim data flows seamlessly into iStow, which executes the recommendation of EA. iStow helps the planner to arrange the stowage of cargoes and ballast water in such a way to achieve the recommended trim. The achieved trim is sent back to EA, to compute the final prediction of fuel consumption.

By integrating iStow with the EA trim optimisation software, safety and fuel efficiency can be addressed at the same time.
