Many on-board and submarine systems have traditionally relied on chemicals that are inevitably released into the oceans to some degree. With the VINGA tank series, Furetank has taken several innovative measures in order to eliminate harmful substances and find new solutions.
Healthy oceans are a prerequisite for a healthy planet and healthy human communities, as stated by the UN. Eighty percent of all life on Earth is found in the ocean. It captures carbon dioxide, controls our climate and sustains us all, providing 50% of our oxygen. Furetank’s Vision Zero goals include no harm to the environment and maintaining healthy oceans.
Furetank always strives to comply with and exceed all applicable customer, national and international regulations. In order to achieve these goals, the company actively participates in research and applies technological advances. These are some of our current efforts.
Furetank’s VINGA vessels are designed to qualify for trade in sensitive areas, holding a VGP (Vessel General Permit) for all oil-water interfaces. This includes the use of biodegradable and environmentally acceptable (EAL) lubricants on all water interfaces. Furetank has made additional effort and investment to extend this practice to all machinery and deck equipment that may cause leaks reaching the ocean, such as cranes, winches, etc.
Airguard seal on propeller shaft
All VINGA series vessels have a ducted propeller. The propeller shaft is equipped with a Wärtsilä Airguard seal, an anti-pollution and environmentally friendly solution.
It works with compressed air which is applied to the empty space between the sealing rings. It is set higher than seawater pressure, resulting in a small amount of air being forced out into the seawater. The void space is connected to an interior drain collection system. Any seawater or lubricating oil that seeps into the void space is automatically vented to the inside, triggering an alarm and preventing the lubricating oil from leaking out or seawater entering the drip tube. stern.
Aluminum anodes on the hull
Most tankers operating in European waters use sacrificial zinc anodes to protect the hull from corrosion. They deliberately release zinc into the ocean. But the research company issued warnings about the harmful effects zinc could have on aquatic organisms, potentially affecting cellular processes, growth and reproductive capacity. Furetank replaced all zinc anodes with the less harmful aluminum alternative.
Ultrasonic anti-fouling system
Box coolers, used to cool various on-board systems, need an anti-fouling system that deters marine organisms from attaching, growing and impairing the functionality of the cooler. The traditional choice is to use copper rods, discharging copper and thus creating a hostile environment for aquatic life.
Furetank is experimenting with a new innovation; an ultrasonic anti-fouling system. It emits sounds that create vibrations on cooler surfaces, preventing organisms from clinging. The result remains to be assessed, but Furetank considers this choice to be a good step towards fewer emissions at sea.
