Marine protection systems (anti-pirate water cannons)

Based on well-proven tank cleaning machine technology, Scanjet anti-pirate water cannons are driven by pressurised cold seawater and will remain running until the vessel is safe and the pumps are switched off. The water beam is fully effective, with rotation speed of 3rpm-6rpm.

To optimise the downward pressure of the water, a block has been installed to restrict the water from being projected upwards. The water cannons can be installed as either a permanent or portable solution and require no chemicals or steam additives.

High-level alarm

Scanjet Independent High Level and Overfill Alarm System is a high-quality product either using acoustic wave or magnetic float reed switch technologies for marine applications. A complete system can be delivered either as a single or dual point system for high level and overfill (high-high) level alarm detection for any kind of liquid, including any hydrocarbons and chemicals.

Water ingress detection

The microwave Water Ingress Detection and Alarm System is designed to detect the presence of water in the cargo holds of bulk carriers. The sensor constantly checks the di-electric constant of the cargo present at the microwave antenna.

Vapor emission control

The VECS system has been developed for safe return of volatile organic compounds to shore when loading tankers. The system monitors the vapour emission and oxygen content in the main vapour collection lines during this operation.

Tank level gauging

Scanjet offers tank level gauging and draft systems for cargo tanks, slop tanks, ballast tanks, fuel and service tanks, using non-contact microwave radar, temperature compensated pressure sensors or electro pneumatic technology.

For cargo monitoring on tankers, the system is one of the most comprehensive and accurate available with the possibility to combine radar and pressure sensors that enable measurement of ullage, volume and density at the same time.

For monitoring level in ballast tanks, the technique is either by a hermetically sealed pressure sensor or by continuously measuring hydrostatic pressure at the bottom of the tank by modulated air through a bubbling probe.

Scanvent high-velocity pressure/vacuum valves

The Mark IV SuperGreen high-velocity valve is the result of dedicated research into creating the ideal compromise between loss of tank vapor and non-oscillating behavior, all in a simple low maintenance package. It features a combination of magnet power and air-breaks, which are unique and patent pending. The non-oscillating Mark IV SuperGreen complies with the two-second no-metal-to-metal contact definition from ISO 15364:2007.
