ARE HNS SPILLS MORE DANGEROUS THAN OIL SPILLS?

Here is a so-called "white paper" for the Interspill International Conference an the Fourth IMO R&D Forum held in Marseille, France, in May 2009. It was recognized by the joint committee of the conference and the forum, that the significant growth observed in maritime shipping of chemical items and the relevant industry and state obligations resulted in the increased attention of the public and industry professionals to the potential dangers of HNS spills.

The HNS stands for the Hazardous and Noxious Substances. The knowledge possessed by the industry today about the fate and potential effects of such spills is much less that the one for oil spills. Everyone involved in transportation of subject cargoes shall be fully aware of all potentially devastating consequences of the spills to the marine environment.

The content of the present white paper has been compiled by the recognized experts of the ITOPF organization and will be very useful for the people engaged in the associated activities. The ultimate intent of the document is to address the most important concerns and key issues related to the HNS spills in comparison to the oil spills, and also to provide a good basis for stimulating open discussion on this matter.

A POCKET GUIDE TO PREVENT BUNKERING MALPRACTICES IN SHIPPING INDUSTRY

In maritime shipping industry of today, the suppliers of bunker fuel tend to employ different dubious practices for the typical operations, and subject malpractices are commonly prevalent in Asian region. Regardless of where the ship is being bunkered, the huge importance of proper and accurate measuring the fuel tanks both prior to and upon completion of the delivery is considered critical phase of all bunker stem operations.

That is why attention shall be paid by the members of the bunkering team taking the barge measurements to the application of the proper trim and list and recording the real temperature of the fuel. Some of the ways of concealing fuel would include hidden compartments and altered lengths of the sounding pipes, short bunker delivery and incorrect sounding tables, doctored gauging devices and others.

The present guidebook prepared by MarineInsight experts shall therefore be of great practical use for the people directly participating in the bunkering process. Apart from the description of different malpractices, the book will provide tips to get better understanding of the bunker gravitating and so-called cappuccino effect, coriolis flow meters, bunker surveys and also different methods and techniques used for detecting concealment of the fuel.
