STOLT TANKERS AND DESMI OCEAN GUARD SIGN BWMS FRAME AGREEMENT.

Major chemical tanker operator Stolt Tankers B.V. has signed an agreement with DESMI Ocean Guard for the installation of the CompactClean Ballast Water Management System (BWMS) across the existing Stolt Tankers fleet.

The agreement is to provide more than 60 sophisticated chemical tankers with the CompactClean BMWS by the end of 2023. Most of the ships will be retrofitted with two CompactClean BWMS, one for each ballast pump. This has the advantage that the ships will maintain full redundancy on their ability to ballast and de-ballast, which is a priority for Stolt Tankers as the ability to ballast/de-ballast is essential to the ship’s ability to load or discharge cargo, and hence the ability to operate.

Herman Heyns, Senior Project Manager at Stolt Tankers, explains: “While strict compliance with all environmental and safety regulations is a must, we always undertake great efforts to be compliant without jeopardising the smooth and efficient daily operation of our ships. After careful consideration, we found that the CompactClean BWMS was the ideal solution for us in order to meet the IMO and US Coast Guard regulations for ballast water treatment. We will be able to retrofit two systems into the pump rooms or on the deck of most of our ships. For Stolt Tankers it is essential to keep our ballast operations as simple as possible, and we do not want to complicate this more than necessary.”

DESMI Ocean Guard is very happy to add a reputable company like Stolt Tankers to the list of customers. “Stolt Tankers is a very well respected company and a true leader in the chemical tanker segment. The fleet of ships owned and operated by Stolt Tankers is top of the line sophisticated chemical tankers, which imposes extra challenges on the BWMS to be retrofitted. Obviously, the BWMS must be approved for installation in hazardous areas (EX-certified), but they also need to be capable of being incorporated in a smooth and seamless manner into the existing automation on the vessel. Therefore, we are particularly proud that after a very careful evaluation and selection process, Stolt Tankers decided for installation of the CompactClean BWMS on the entire existing fleet. With the very small footprint, ease of operation, and completely chemical free treatment of the ballast water, CompactClean is a good and safe choice for chemical tankers,” explains Rasmus Folsø, CEO of DESMI Ocean Guard A/S.

DESMI’s CompactClean BWMS has IMO, USCG and Lloyds Register type approval, and the BWMS operates in the exact same way both inside and outside US Territory.

The CompactClean BWMS is available in an ATEX and IECEX certified version, making installation in hazardous zones onboard oil, chemical or gas tankers possible.

The operation of the system is based purely on mechanical treatment and therefore it does not involve any use of chemicals or active substances. This eliminates risks of hazards to crew, vessel or the environment. First treatment step is filtration, second step is UV treatment. During de-ballasting, UV treatment is repeated, but the filtration step is omitted.

CompactClean has no salinity or temperature limitations. It delivers compliant performance anywhere in the world in even very dirty and challenging water conditions. This superior performance comes from the unique and patent pending shape of the UV chamber, which has been carefully developed and optimized through hundreds of state-of the-art CFD (Computational Fluid Dynamics) simulations.

CompactClean automatically reduces flow through the system to ensure compliant treatment even under extreme conditions. This enables the vessel to carry on with its port operations instead of forcing the vessel to interrupt the ballast water discharge.
