Sampling and Analysis of Ballast Water in the Context of PSC

The underlying principle of Port State Control procedures is that sampling and analysis of ballast water treated onboard a vessel will not be more stringent than what is currently required for the scope of type approval. Port State Control procedures will be globally implemented when the International Convention on Ballast Water Management becomes effective. Sampling and analysis of ballast water is a complex issue while ships’ inspections are also a matter of concern. Thus IMO recently issued revised guidelines on ballast water sampling for trial use as BWM.2/Circ.42.

Ballast Water Treatment Systems Selection and Use

If someone wonders why to install a Ballast Water Treatment System, the answer is that it has to do with legislation; one comes from IMO and the other one from USCG. These two are the driving force for all of the suppliers to develop a system and for the shipowners to install a system at some point from today until 2016 and onwards. But before choosing a system, the available technologies have to be checked. I dare to say that nowadays the technologies are pretty mature and there are quite a few of them, so many choices exist for different shipowners, types of vessels and trading routes.

Minimal Ballast Water VLCC Design

On 25 February 2013 Namura Shipbuilding acquired AIP (Approval in Principle) from NKK regarding the MIBS (Minimal Ballast water Ship) VLCC project, for which the company has been working for years together with Shipbuilding Research Centre of Japan and with the support of Japanese Government.  This tanker design reduces the weight of ballast water required by about 65 percent compared with a conventional hull form.
