The 'virtual' double bottom

Article Abstract:

Very large cargo carriers that are 25 years old can have an extended service life by converting their single hulls into hydrostatic balanced loading (HBL). According to Concordia Maritime, the conversion would not only extend VLCCs life but also increase their environmental protection in the event of grounding. In HBL, the cargo level is slightly reduced while inert gas pressure is kept to a minimum inside the ullage space. The result is lesser pressure exerted by cargo compared to the water pressure under the hull.

Paper carrier offers versatility

Article Abstract:

The Baumwall is a 4,500 dwt paper carrier completed recently by Denmark's Nordsovaerftet AS for Schiffahrtsgesslschaft Wolfgang Hammann KG. Now in service between Norway, Gent and Hamburg, the Baumwall is the first of two vessels of its type, with the other scheduled for delivery to another German owner sometime in 1996. A brief overview of the Baumwall's design and its distinguishing features is presented.
