Overview of Seawater-Compass

Seawater-Compass models and predicts the corrosion rate and remaining service life for metals and alloys used in seawater services. Seawater-Compass is the only device and OS independent software tool on the market for the modeling and life prediction of seawater corrosion of metals and alloys including carbon steels, aluminum alloys, brass, copper-nickel alloys, nickel alloys, stainless steels, duplex stainless steels, and titanium alloys. Designers, OEM engineers, consultants, operation personnel, maintenance and inspection engineers can quickly and accurately determine: (1) the seawater corrosion rate of the selected metal or alloy; (2) the remaining life of the equipment or component; (3) the major forms of corrosion expected in seawater services, (4) the cautious notes on (a) the high risk of stress corrosion cracking (SCC) when the temperature exceeds the threshold; (b) the risk of erosion corrosion and cavitation when the seawater velocity is high; (c) the risk of pitting, crevice corrosion, and microbiologically-influenced corrosion (MIC) when the velocity is too low.


Figure 1 below shows an overview of Seawater-Compass. Users simply select one of the 50 metals and alloys from the list (Figure 2). Seawater-Compass models the effects of seawater temperature, seawater salinity, dissolved oxygen concentration, and seawater velocity on the seawater corrosion and predicts the corrosion rate and the remaining life of equipment or component under the prevailing operating conditions.

Seawater-Compass is a cloud-based software that works on any device running any OS without the need for users to install or download anything. Experience the industry's first cross-platform and device-independent seawater corrosion modeling and prediction app on your iPads, tablets, smart phones, notebooks and desktops, at any time and anywhere, in the office or in the field. No installation files to download, no browser plug-ins required, no USB dongles to carry around, and no license keys to transfer from one PC to another. Seawater-Compass simply works on any device running any OS. All you need is an internet browser.


In the application example in Figure 1 above, the predicted corrosion rate of carbon steel in seawater of salinity of 35‰ is 0.943 mm/y at the operating temperature of 45°C and seawater velocity of 1.5 m/s. Seawater-Compass predicts that the major forms of corrosion expected is general attack, pitting, and microbiologically-influenced corrosion.

Figure 3 Seawater-Compass predicts the risk of pitting and microbiologically-influenced corrosion (MIC) under low flow or stagnant condition.


In Figure 3 above, the seawater velocity is low, at 0.1 m/s. Seawater-Compass predicts the risk of pitting and MIC with a cautious note for the user. In Figure 4 below, the seawater temperature is high at 60°C,  Seawater-Compass predicts the risk of chloride stress corrosion cracking (SCC) for type 316 stainless steel. In Figure 5, Seawater-Compass predicts the risk of hydrogen embrittlement for titanium in seawater services.

Figure 5 Seawater-Compass predicts the risk of hydrogen embrittlement (HE) of Titanium in seawater services.

The powerful applications of Seawater-Compass are truly unlimited in engineering design, materials selection, process operation, inspection and maintenance, corrosion risk assessment, setting the IOW limits, corrosion modeling and remaining life prediction.
