Although the text remains vague, halfway as it is through a series of four drafting conferences, the main area of focus is clear: where there is biodiversity that can be exploited, it must also be protected.
Such measures will require environmental impact assessments and area-based management tools, including the creation of protected areas. Other areas of focus for BBNJ include cataloguing marine genetic resources and sharing capabilities to profit from them so that smaller states do not lose out. But for shipping, it is those impact assessments and protected areas that should trigger alarms.
There is little doubt that impact assessments will place an emphasis on the potential pollution to, and disturbance of, marine life.
Shipping is no stranger to regulation in this regard via IMO, but with BBNJ, the onus will rest with individual states to regulate the companies under their jurisdiction.
Proving, reporting and monitoring compliance with any new requirements on a country-by-country basis will be a new burden for shipowners and operators.
So too will having to avoid protected areas of the ocean or having to adopt new operating procedures for passing through them. Tighter regulation will mean that demand for environmentally friendly shipping solutions will grow significantly over coming years good news for technology suppliers, perhaps less so for some shipowners.
That said, any new burden posed by BBNJ is really nothing more than a continuation of the trend for tighter environmental control, something which shipping is already familiar with. It is imperative however that shipping contributes at the drafting stage. Leaving representation up to associations is not an option, he said; only by participating can shipowners guarantee that their own concerns are heard before it is too late.
The theme of the Nor-Shipping conference and exhibition in June encourages shipping to embrace the diversity of ocean opportunity. I agree with that sentiment. In recent months I have covered new potential ocean business ranging from the large-scale shipping of CO2 for carbon capture and storage to those vessels needed to support seabed mining. All require not just vessels and potentially new types of vessel, but even new ship technology.
That opportunity should excite marine engineers and shipowners. But for every opportunity there is an associated challenge. As the potential of the ocean continues to reveal itself it is reasonable that shipping, along with other sectors, should be asked to use it in a sustainable manner.
Bad system integration prevents root cause analysis Commercial pressures are preventing the better integration of control and automation systems that could help identify root causes of equipment failures. The specifications that shipowners provide to ship designers often touch only superficially on control systems and integration requirements.
Without specifications for connections and the definition of valuable outputs, shipyards have little incentive to go beyond these limited requirements. Mr Nogva argues that suppliers should relinquish their own control systems or adhere to onerous requirements for how these systems are connected to each other.
A lack of specification and subsequent poor integration also limits the potential advantages of holistic design and propulsion packages provided by big marine technology companies. It is not just a problem for suppliers, shipyards and naval architects.
Shipowners would need to train their crew better too, as well as educating management on land about the better use of integrated systems.
Mr Nogva suggests that simulators could be deployed to this effect. The growing demand for reporting and documentation — of fuel consumption, emissions and efficiency among other factors — as well as the need to manage vessels better, will bring increasing numbers of individual systems onto ships. This proliferation of hardware and software is already making life difficult for some owners and, says Mr Nogva, lifetime costs are high as these elements often need to be replaced after a few years.
That, he believes, means asking more from ship designers, class societies, regulators and shipyards. It is a holistic approach that has been lacking to date, but could be the key to unlocking big improvements in safety and reliability. In a world of fluctuating fuel costs and stringent emissions targets, we are passionate about operational simplicity.
X-DF engines offer new marine propulsion standards with low-pressure gas technology. For a smarter perspective on your low carbon future, a partnership with WinGD ensures efficiency and sustainability. A quiet revolution in underwater noise The impact of ship noise on marine life is driving a new focus on less obtrusive propulsion systems.
The noise reduction element of the programme has been in place since and supports further port authority-led projects focusing on whale welfare, including the Enhancing Cetacean Habitat and Observation research programme to reduce the effects of shipping on whales. To take one example, the EnergoProFin deploys fins that rotate together with the propeller. This reduces the cavitation caused by the hub vortex. It also reduces the energy losses caused by the flow phenomena around and behind the propeller boss, thereby increasing overall propulsion.
To date, it has been installed on more than vessels. It is no surprise that other equipment designers are beginning to target the noise reduction market. This reduces propeller tip vortex cavitation by applying a small number of strategically bored holes in the propeller blades. This is claimed to give a quieter propeller with minimal compromise on efficiency.
Canada is the first country in the world to encourage quieter ships for the sake of its whale population. It is unlikely to be the last. An underwater noise limit on an IMO level may be some way off, given the pace of international regulation. DMC is applying its years of experience in winch technology to the delivery of high quality, cost-effective custom and standard winches, with first time options including constant pressure CP.
DMC: your knowledge centre for winches. And of course, they enable the continued use of high-carbon fuel. The drop in pressure that selective catalytic reduction SCR causes is known to engineers — lower pressure means that more energy and therefore more fuel is required to push gas through the unit. But Mr Baan explains that the big issue for SCR as engines become more efficient is exhaust gas temperature. More efficient engines mean less waste heat and lower exhaust temperatures. The two-stage turbocharging process on the engine means that the exhaust gas provides little heat for the catalytic reduction process, so a high-temperature tuning called High T6 reduces the engine efficiency.
For more than one reason, gas-burning engines may hold the answer. For the lower-carbon fuels such as LNG, it deploys either pure-gas, spark-ignited engines or dual-fuel engines, both of which use the lean-burn Otto cycle combustion principle.
For conventional, higher carbon fuels, it uses Diesel cycle engines with a higher injection pressure. As well as having an impact on CO2 emissions, this also has an impact on NOx formation and therefore the efficiency that can be achieved in an engine. It means that. In the future we may even see three-stage turbocharging. We know that engines using gas will benefit much more because this temperature constraint is not there.
But although using low-carbon fuels is a step in the right direction — enabling reduced CO2 both inherently and by not demanding emissions aftertreatment — it is not enough. The initial results, using standard engine tunings, were not entirely encouraging. The combustion characteristics of hydrogen meant that combustion was accelerated. This extra heat led to an increase in NOx formation. The faster heat release also meant that peak pressures within the cylinder were higher.
Methane slip was also reduced due to the more violent combustion of hydrogen burning the gas more completely.
By using alternative injection and spark timings to try to bring NOx down to Tier III compliance, researchers were able to lower the impact that the hydrogen content had on heat pressure, as well as offering lower total carbon emissions. So going slowly saves fuel and if you really want to save fuel you need to downsize your plant.
That is the hybrid opportunity. And while our experience of electric vessels is that they are great if you want to take a 20 km trip, it is quite a different story if you want go 1, km in one go.
The idea is that engines run on a continuous load, with batteries discharging when a peak demand is encountered and charging when the engine output exceeds energy demand. But Mr Baan is not convinced that is always a good solution.
So you have a big engine or a number of gensets running part load in case the load increases. But if you can scale your engines for average power and then use energy storage — whether it is batteries or supercapacitors or something else — to take the peaks, that would be a more efficient solution.

Hybrid Cars -- Pros and Cons
The phrase refers to technologies that mitigate or avoid pollutants or CO2 emissions generated by converting coal for electric energy…. A water snail can walk on water so to speak because it finds the perfect balance between surface tension and viscous drag…. When you take Tylenol or Advil for a headache or a sore muscle, the pain disappears. The fact is, most medicines are pretty dumb in this respect…. Modern particle accelerators are either linear, where the particles are accelerated in a straight line, or circular, such as the Large Hadron Collider LHC that just started operating at CERN…. When a Boeing comes barrelling down the runway at plus mph, it sometimes feels to its passengers like the plane is struggling mightily to stop. Of natural gas, fuel oil, and electricity, natural gas takes the prize right now as cheapest energy source…. Stunt shows are, of course, another story….

Another frequently seen statement is that the sixteen worst offending vessels create as much pollution as all the cars on the planet combined. Can this really be true? Was shipping not supposed to be the most environmentally friendly mode of transportation out there? When I read the article, I felt a strong desire to open Excel and run a few simulations of my own on the topic.

Despite both companies at the end of last year looking at expanding their joint research into a high-tech engine, the synergies weren't providing the cost benefits desired with the small engine, so the affair has come to an end. Mercedes recently broached the idea of working with BMW on a frugal, low-emissions motor, a public offer that has gone unanswered by BMW. Nevertheless, with the large number of B-segment cars in development by numerous manufacturers, it would seem likely that people are going to be partnering up again sooner or later.
