The Australian Federal government has announced an additional $10 million in funding for the launch of the National System for Domestic Commercial Vessel Safety (National System) administered by the Australian Maritime Safety Authority (AMSA) which began on 1 July this year.
With a myriad of emergent new technologies on the horizon of the maritime industry, such as autonomous vessels, it is vital that regulations are established to ensure the safety, security and efficiency of a new generation of ships.
Just as car companies are betting big that self-driving vehicles will change our roads, shipping companies are making a similar bet that automation will change how we move goods around the world.
Norwegian start-up technology firm ScanReach is set to redefine safety standards at sea with In:Range, a unique system capable of locating anyone on a vessel or offshore installation in real time. The plug and play technology is deceptively simple, easy to install, low cost and, according to the team behind it, could save countless lives at sea.
A Human Factors Dimension to Your SMS
The need to have a Fatigue Management Plan (FMP), which is often viewed as a daunting task for operators of all sizes and complexities. In reality though, if seen as an extension of your existing SMS, the challenge is not as big as you might think. And, an FMP delivers many benefits with minimal impact to your business workflows.
It is a long held traditional belief that fish do not feel pain the way that humans do, largely due to the fact that they have unsophisticated nervous systems, and lack brains complex enough to generate a conscious awareness of pain. However, after extensive research, fish biologists around the world have put together considerable evidence to indicate that fish do, in fact, feel pain.
There are several types of seals, which are divided into two key groups – face seals and lip seals.
Both use an articulated rubber sleeve to keep the water out, and are similar in appearance, but lip seals seal via a lip, or sometimes two, whereas a face seal uses a collar that attaches to a surface on the end of the articulated hose.
Considered the most efficient way to seal a shaft, the PSS (Packless Sealing System) shaft seal is a mechanical face seal, which uses the seal created between the flat surfaces of the rotating stainless steel rotor and the stationary carbon flange. The carbon flange is attached to the stern tube via an articulated rubber bellows. The carbon flange contacts a stainless steel rotor that fits securely around the shaft, and is fastened on with grub screws and seals via two O-rings sunken into its bore. The bellows is installed on the stern tube and is then compressed a set distance by the stainless collar, creating a solid and even seal between the carbon flange and the stainless rotor.
Volvo Rubber Stuffing Box
Volvo Penta’s solution is commonly called a ‘rubber stuffing box’, and is quick and easy to install, and takes up minimal space, as it combines the rubber hose with a lip seal in one assembly, with no moving parts. It has an internal, water-lubricated bearing and lip seals which must be greased annually. It comes with a single, wide hose clip, secured with machine screws, to clamp on to the stern tube. As it does not have a pressurised water feed, after launch, it must be ‘burped’ to remove air.
Tides marine Sure Seal and seriesOne
This is a propeller shaft sealing, which is suitable for a wide range of shaft speeds and ambient operating temperatures, and commonly fitted to power boats, yachts and commercial crafts. Created from fiber-reinforced composite material that is non-corrosive, it is strong, durable and practical, as there are no moving parts. A pressurised cooling water supply is required to lubricate the lip seal and alignment bearing in the seal head. The seriesOne model is produced in the same way as the Sure Seal, yet is designed for smaller, single-engine vessels with stainless steel propeller shafts.
Biological invasions are widespread throughout the world’s oceans, with many of these invasions occurring as a result of human-mediated mechanisms.
Marine vessels are largely responsible for facilitating the movement of aquatic pest species across bioregions, as small marine animals and plants easily attach to the submerged surfaces of a vessel, as it moves through the water.
The maritime industry is dominated by men, with only a small portion (~2%) of the marine workforce held by women.
A majority of women who do work in the industry tend to do so in the cruise and ferries sector – primarily taking on service roles, such as hotel staff, catering, kitchen duties, cleaning etc.
