Control And Management

Ratification of the International Maritime Organization (IMO) International Convention for the Control and Management of Ships' Ballast Water and Sediments (BWMC)[i] has now forced the hand of operators and ship owners to comply with the BWM, and without a great deal of time to react. The need to integrate and operate Ballast Water Treatment (BWT) Systems on In-Service ships, however, is not new, and BMT have recent and relevant experience in end-to-end BWT system solutions. In 2011 BMT Defence Services Ltd (BMT) produced the installation specification to enable A and P Falmouth Ltd (A and P) to carry out a ballast water treatment plant retrofit installation on the RFA Bay Class ships (i.e. RFA MOUNTS BAY, LARGS BAY and CARDIGAN BAY), enabling the ship to be approved and operated in compliance with the BWMC. In addition, BMT produced documentation to enable A and P to arrange, manage and perform the necessary test, trials and commissioning to prove the equipment installation and that it can be operated in accordance with the requirements of the BWMC. The objective of this paper is to take the reader through the process of design and embodiment of a BWT system retrofit on a relatively complex (with respect to the ballast system) ship. The Bay Class ships are Landing Ship Dock (Auxiliary) ships with separate forward and aft ballast systems (to allow the ships to function in their amphibious roles by way of their stern dock), and a ship wide Ballast Stripping system. Key design and engineering considerations are discussed below and recommendations for the installation of a ballast water treatment system are also offered.

ABSTRACT Approximately 12 million gallons of oily ballast water is taken ashore and treated daily at the Alyeska treatment plant, where tankers take on crude oil at the terminus of the Trans Alaska pipeline near Valdez, Alaska. Most oil is removed, but some light aromatic hydrocarbons (1 to 16 parts per million) remain in the large volume of discharged effluent. Between May and July, the concentration of aromatic hydrocarbons in the treated effluent (measured by gas chromatography) generally declined as the seasonal temperatures increased. We measured the toxicity of the effluent on site at Valdez. For the larvae of crustaceans and of fish the median lethal concentration LC50 was between 10 and 2p percent of treated effluent in 96-hour static tests. For salmon fry and shrimp in repeated acute flow-through assays, the (LC50) was quite consistent, between 20 and 40 percent of treated effluent. Because the concentration of aromatic hydrocarbons was much lower in the later tests but the toxicity of the effluent was not lower, toxicants other than aromatic hydrocarbons must contribute significantly to the toxicity of the effluent from the ballast-water treatment plant.

In order to protect the world from the invasive species of organisms the cleaning ballast water is required, in other words, discharged water must meet requirements posted by the International Maritime Organization (IMO). The paper provides a comparative analysis of ballast water treatment equipment and its technical parameters. The research has been performed to analyse and assess the effect of the introduced equipment on ship stability, including the effect of its weight, dimensions, performance, price and the efficacy of choice.

Ballast Water Treatment Systems

Having come into effect, the International Convention for the Control and Management of Ships’ Ballast Water and Sediments of 2004 requires ships to process their ballast water in accordance with specific standards. Different processing methods require different use of ship power, thus affecting fuel oil consumption, ships’ energy efficiency, and the ship economics in general. This paper presents the analysis and comparison of the economic viability of systems using two dominant ballast water treatment methods on merchant ships. The cost effectiveness of these methods, UV irradiation and electrochlorination, is compared to the standard efficiency of ballast water exchange using sequential flow method as a reference. The process efficiency is measured through fuel oil consumption on board. Taking into account possible variations in efficiency due to different designs and environmental constraints and assumptions, the findings are in favor of the electrochlorination method.

Ballast Water Treatment Systems

This review paper summarizes the legislative framework and the available technologies for ballast water treatment with regard to the approval process and relevant issues. The International Maritime Organization (IMO) sets the limits of organism concentration in ballast water allowed to be discharged into the sea. The 2004 International Convention for the Control and Management of Ships Ballast Water and Sediments is the first international document that introduced obligatory ballast water management and control. Even though ballast water treatment systems are not 100 % effective, they significantly reduce the risk of spreading of invasive species through ballast water exchange. An increased manufacturer interest in the system’s approval or development of new technologies is not expected in future because the procedure is time-consuming and expensive. The final choice of optimal ballast water treatment system depends on the ship owner or operator taking into account the price, type of the ship, whether it is a newbuilding or an existing ship, ballast system capacity and the seas where ships ply as well as harbours at which they call.

Control And Management

Ships use ballast water to ensure their buoyancy and stability. A significant amount of them is transported in various water basins of the World Ocean. Thus, together with ballast water, many microorganisms, phytoplankton and zooplankton are transported. The constant increase in the number of ships in the World Merchant Navy increases the risk of the spread of these invasive species in the local aquatic environment. This led to the decision of the International Maritime Organization (IMO) to legalize the control and treatment of ships' ballast water in order to minimize the risks of the spread of these invasive species.. Their transfer through ballast water to a new water environment is estimated as one of the 4 largest treats for the World Ocean. The International Convention for the Control and Management of Ballast Water and Sediments plays an essential role in the control of ballasting and de-ballasting processes. It regulates the D-1 and D-2 standards, as well as various ballast water treatment systems. Improving the possibility of subsequent change in the application of invasive species, the only way to solve this problem, is to fully prepare for ballast water and to develop alternative methods to ensure the buoyancy and resilience of ships.
