Seawater Electrochlorination Systems

Seawater Electrochlorination systems are developed as the go-to solution for control of marine biological fouling in the offshore oil and gas industry. They provide the most effective and environmentally safe method for the prevention of biofouling that would negatively affect the seawater systems within an offshore facility. Frames designs, manufactures and supplies custom-built seawater electro- chlorination systems for a broad range of seawater process applications.

About our Seawater Electrochlorination Systems

Seawater electrochlorination systems typically consist of a core electrolyser cell arrangement with associated transformer/rectifier, dosing pumps, storage tanks and process piping. The system produces in-situ, a dilute, safe solution of sodium hypochlorite for direct injection into the seawater circuit. Frames can advise on sparing philosophy for each application in order to optimize the design. Our systems include the always clean Concentric Tubular Electrode design which does not require acid washing or other electrode cleaning methods.

Optionally, we can deliver a seawater electro-chlorination system as part of an integrated solution, thus reducing onsite installation and commissioning time. Thanks to years of experience in designing and assembling equipment for flow assurance, Frames offers the valuable know-how required for advising effective solutions. Our in- house multidisciplinary engineering capability ensures that each seawater electrochlorination system is designed in accordance with client specifications and local legislation. Being supplier-independent, Frames is in an excellent position to select the best solutions, striking a balance between capital investment (CAPEX) and operating costs (OPEX).

Our approach to seawater electrochlorination

One of the main challenges in the upstream processes of the oil and gas industry is to protect pipeline and process equipment against biological fouling. The engineering disciplines involved in protecting seawater processes play an essential part in the prevention of production downtime due to the effects of  macro and micro fouling. Restriction of cooling water flows, acceleration of corrosion and a reduction in the overall life of process equipment can all be controlled by the effective design of your electrochlorination package. Frames Seawater Electrochlorination Packages play an effective role in optimizing flow assurance.
