#55 LED LIGHTS IN MARINE INDUSTRY

-

LED makes its way across more and more in Marine/ Industrial applications. In today’s maritime industry, the term ‘Energy Efficiency’ is of sheer importance in all aspects of shipping operation. From main engine to cargo operations, energy efficiency has become the base to set up and plan any machinery or procedure. Electrical system being the most important network onboard ships, it is important for ship owners and operators to make their energy efficiency plans considering the same.

Use of energy efficient LED lighting in place of conventional lamps and tube lights on ship, contributes to more savings and add up to its energy efficiency model. An incandescent globe (bulb) can provide a life span of 1000 hrs and a fluorescent lamp can be used up to 7500 hrs. However, far better performance can be achieved by LED lights which have lifespan of about 50,000 hours and 60% less energy consumption. Implementing this would not only reduce the maintenance hours but also bring down the operating costs in thousands every year, which includes the generator fuel cost and operation/maintenance cost of the lights.

Benefits of using LED lighting onboard ships:

Less time in dangerous situations: LED bulbs last an average five times longer than traditional bulbs. This means crew spends up to 80% less time up on ladders and lifts replacing them.

Reduces vessel’s electrical load: LED lights use approximately 50% less energy – with higher-end fixtures saving as much as 70%. Less energy used by your lighting means more energy can be utilized elsewhere on vessel.

More horsepower to where you need it: With less energy used by lighting, more horsepower can be directed to pumps, motors and hydraulics. This also lessens the load on switchboard, giving it longer life.

Lowers operating costs: Reducing the energy needed for vessel’s lighting by 50% – or even 70% with higher end solutions – lowers costs to generate that energy, too. Generators will last longer and need less fuel to create the energy needed.

Reduces maintenance costs by up to 80%: LED lights are more durable and less prone to failures due to vibration, temperature, and impact – perfect for maritime vessels. LED bulbs are shatterproof and can withstand impacts that traditional bulbs won’t. Their temperature resistance is well-suited to extremes of hot sun and cold water, not to mention rapid shifts in weather. And vibration is always a long-term and permeating condition on any vessel.

Increases small target visibility by as much as 50%: This helps crew pinpoint hazards both on and off the vessel.

LED lights are safer to handle: Because they’re cool to the touch, you eliminate those safety concerns normally associated with working around and handling hot bulbs.

Better identification and avoidance of hazards on your vessel’s deck: LED lights are hemispherical, rather than 360°. So they can be configured directionally, purposefully shining into the darker areas where you need them. This also provides more efficient use of light, with less spill and waste.

Flexible illumination control: LED lighting can be configured to provide multiple beam angles per fixture. This gives you the flexibility to tailor where the light is targeted for whatever situation you’re in.

Crew is safer when an LED light breaks: Unlike CFL or fluorescent lighting, LED lights are completely non-toxic. There’s no exposure to hazardous chemicals when an LED light breaks. And the shatterproof material is less dangerous than falling glass, too.

Immediate lighting when needed: LED lights turn on immediately – no more waiting for the annoying “warm-up.” Plus no more re-strike issues from switching off your forward mast lights when approaching another vessel. Traditional bulbs degrade and lose illumination with each re-strike, a fact every captain hates. LED lights don’t need to re-strike and don’t experience that degradation. Not only that, but the lights also come right back on when the other vessel’s passed.

Lowers vessel’s carbon footprint: This can help to meet environmental and emission standards. Because LEDs use much less power, there is less carbon dioxide generated as a byproduct of that power.

Better visibility in challenging weather: LED lighting offers a variety of colors, including the traditional, yellowish HPS-type color. As this color believed to penetrate through snow, fog, and spray better than white light. So we get the best of both worlds – the penetrating color of a typical high-pressure sodium light, with the energy savings and durability of LED.

Less glare and eyestrain : The neutral white color available in LEDs minimizes issues of glare and flash back. This is perfect for deck applications and places less strain on the operators’ eyes during long night-hour shifts.

Conclusion

The advent of energy efficient LED lighting products not only provide better living and working environments, but also contribute in a cost-effective manner to the global reduction of energy consumption and greenhouse gas emissions.

#18 10 Main Personal Protective Equipment (PPE) Used Onboard Ship

-
Image
  Safety of self and co-workers is the prime priority kept in mind by a professional seafarer while working onboard ship. All shipping companies ensure that their crew follow personal safety procedures and rules for all the operation carried onboard ships. To achieve utmost safety on board ship, the basic step is to make sure that everybody wears their personal protective equipments made for different types of jobs carried out on ship. Following are the basic personal protective equipments (ppe) that are always present onboard a ship to ensure safety of the working crew: Protective Clothing : Protective clothing is a coverall which protects the body of the crew member from hazardous substance like hot oil, water, welding spark etc. It is popularly known as “dangri “or “boiler suit”. Helmet : The most important part of the human body is the head. It needs utmost protection which is provided by a hard plastic helmet on the ship. A chin strap is also provided with the helmet which k...

#68 MANNED SHIPS ERA TO ARTIFICIAL INTELLIGENCE CONTROLLED SHIPS ERA (iota-4)

 Differences between IT and OT systems Whereas IT systems manage data and support business functions, OT is the hardware and software that directly monitors/controls physical devices and processes and as such are an integral part of the ship and must function independently of the IT systems onboard. The systems can, however, be connected to the IT network for performance monitoring, remote support etc. Such systems are sometimes referred to as belonging to the Industrial Internet of Things (IIOT). There may be important differences between who handles the purchase and management of the OT systems versus IT systems on a ship. IT managers are not usually involved in the purchase of OT systems and may or may not have a thorough understanding of cyber security. The purchase of such systems should involve someone, who knows about the impact on the onboard systems but will most probably only have limited knowledge of software and cyber risk management. IT covers the...

#41 Maritime Cybersecurity

Maritime is one of the oldest industries and lifeblood of the global economy, accounting for the carriage of 90% of world trade. Ships and other vessels may seem like unusual targets for cyberattacks. But with their growing use of industrial control systems (ICS) and satellite communications, hackers have a new playground that’s ripe for attack. In a 2020 Safety at Sea and BIMCO Maritime Cyber Security survey, despite the majority of respondents (77%) viewing cyber-attacks as a high or medium risk to their organizations, few appear to be prepared for the aftermath of such an attack, 64% of respondents said their organization has a business continuity plan in place to follow in the event of a cyber incident, but only 24% claimed it was tested every three months, and only 15% said that it was tested every six to 12 months. Only 42% of respondents said that their organization protects vessels from operational technology (OT) cyber threats, and some respondents went so far as to describe...
