  • Bulk Carrier Ballast Water Treatment System Retrofit

    Discharging untreated ballast water can have serious environmental consequences, yet successful integration of ballast water treatment systems onto vessels is a complex undertaking. In 2014, The CSL Group (CSL) engaged Glosten to determine the practicality of such an installation and establish a standard retrofit approach for CSL to utilize across its fleet.

    We Love a Challenge

    Sheila Ann, a Panamax self-unloading  bulk carrier owned by CSL and operating in the CSL Americas fleet, was scheduled for drydocking in December of 2014. CSL tasked Glosten with determining the feasibility of retrofitting the vessel with a ballast water treatment system and sulfur exhaust gas cleaning system.

    Cutting-Edge Laser Scanning Technology

    During a two-day anchorage, the Glosten team surveyed and scanned the vessel using a laser scanner with 2 mm accuracy at a range of up to 330 meters. The 3D data from the scans, coupled with Glosten’s extensive experience in understanding vessel design and operations, informed the feasibility and practicality analysis of installing a ballast water treatment system onboard the vessel.

    A Solution for the Future

    Following the feasibility study and system selection, the Glosten team developed an installation design for the vessel. The design team then leveraged the scan data to develop shipyard contract and detail packages, never again needing to visit the vessel for additional survey – saving the client time and money. A geographically diverse team, from Norway to China, used the scans and models to effectively communicate and execute the retrofit, which concluded in March of 2015 as part of a larger drydock maintenance period.
