The problem with ballast water is that it is almost never just water.
This is particularly noticeable when vessels have ballasted in ports with particularly muddy beds. Once this material is settled and no longer in suspension, i.e. over the duration of a voyage it will almost never flow out with the ballast water in the quantity it flowed in.
Due to this a build-up of material appears.
Between a special survey period of 5 years, these deposits can build to a significant volume. In order for inspections to be carried out class society will require unhindered access to a clean surface in order to make their assessments.
This is where Dickerman Overseas Contracting Company Limited have vast amounts of experience utilizing our in house designed and manufactured equipment the Si-Jet (please also see section on Si-Jet) in order to remove mud and other natural deposits in the most time and cost-effective manner possible.
Overall our projects are hugely cost-effective, when compared with the costs of having material removed in dry dock (which is nonindigenous to the area) it is classed as hazardous waste and as such comes with huge disposal bills. Our teams are able to efficiently remove the mud and pump it back to where it originated, the sea.
Our experienced teams, specialist Si-Jet equipment, and methods are hugely beneficial to owners requiring clear access to ballast tanks and we would welcome the opportunity to discuss these services in further detail.
