Tugs rendering assistance are operating in close proximity to a ship. If the ship has speed on, it may include risks for the tug, its crew and the ship to be attended. This is caused by the interaction effects between ship and tug and as a consequence the tug experiences suction forces and turning moments which vary quickly near the bow and stern of a ship.  The smaller the distance between tug and ship and the higher ship’s speed, the...

Fuel Cells Tested for First-Ever Hydrogen Hybrid Ferry Conversion

By ABB 2019-04-11 11:36:35

ABB and the SINTEF Ocean laboratory in Trondheim will assess how fuel cells and batteries can best function together for short-distance ferry operations, and how Fiskerstrand can integrate them with other engine room systems. The tests will also provide insight into the introduction of hydrogen fuel cells for future reviews of the rules covering shipboard use of hydrogen. The tests will simulate the conditions the ferry is expected to encounter on a high frequency 10km route to ensure that the...

IMO 2020 Stability and Compatibility Headaches

By Ara Barsamian and Lee Curcio 2019-04-07 16:59:46

2020 will be a mess from fuel oil stability and compatibility point of view. 2020 is clearly price-driven, so the temptation to “cut corners” is great, meaning a set of highly variable number of blend components to manufacture the fuel oil will open a “Pandora’s Box” of  large  numbers of complex and questionable formulations.  Fuel Oil Component Order of Blending Exhaustive studies of the relationship between asphaltene content and aromaticity have shown that the order in which we do the...
