Fluid dynamics is the study of non-solid matter: that which is mutable, volatile and mercurial! The analogies with the complex world of gas and seaborne LNG trade are obvious. But just as fluid dynamics is a framework for analysing the maelstrom of physical reality, so too can the gas trade be viewed through various helpful frameworks, for example that of the changing global energy mix.

The shipping industry is essential to the smooth functioning of the world economy, transporting around 85% of the world’s international trade in tonnage terms. So it comes as no surprise that ships are all over the world at any given time. However, the ability to identify ships’ positions by vessel tracking systems today means that one can be more precise than ever in breaking this down a little further…

Shipping industry cycles are constantly influenced by the twin factors of supply and demand, and for investors if it’s not time to worry about one, it’s the other that’s causing concern. With much of the post-financial crisis era focussed on supply-side issues, albeit following a huge shock to demand, risks to seaborne trade growth began to feature more prominently in recent years, but how do things look today?

Just prior to Halloween, the UN announced that levels of CO2 in the atmosphere reached new record levels of 403 ppm in 2016. The shipping industry remains a broadly efficient transportation solution in terms of emissions per tonne of cargo, but the news will only increase the focus on what new action may now be necessary, against the spectre of substantial fleet growth over the last decade.

Historically, the fuel of choice for the vast majority of large cargo ships has been heavy fuel oil. But in 2020, sulphur oxide emissions will be capped to 0.5% by IMO convention, ruling out current standard grades of HFO. Both fuel consumers in the shipping industry and producers in the refining industry have now had a little time to consider the potential options to deal with the imminent regulatory change…

“Look after the pennies and the pounds look after themselves” goes the saying, a mantra the shipping industry has a long taken to heart. In this week’s Analysis, we review trends in ship operating expenses (OPEX) that have taken the total cost base of the shipping industry through the $100 billion barrier for the very first time.

Watching The Pennies!

Of all global industries, perhaps few have had the extreme cost focus of shipping over the past 30 years. During the 1980s recession, any operating “fat” was largely removed with the growth of open registries and a drive to outsourcing. This helped shipping, alongside its near “perfect” competitive economic model, deliver exceptionally cheap and secure freight, in turn a key facilitator of globalisation.

Nice And Lean…

OPEX response since the financial crisis has been relatively modest. Our average OPEX index (using the ClarkSea “fleet” mix and information from Moore Stephens) shows just a 1% decrease in OPEX since the financial crisis to $6,451/day in 2016. By comparison, the ClarkSea Index dropped 71%, from $32,660/day in 2008 to $9,441/day in 2016 (a record low). In part, this modest, albeit painfully achieved, drop reflects upward pressures from an expanding fleet and items such as crew and ever- increasing regulation. However it also reflects the already lean nature of OPEX.

$100 Billion And Counting…

Our estimate for aggregate global OPEX for the world’s cargo fleet has now breached $100 billion for the first time, up from $98 billion last year and $83 billion in 2008. The largest constituent remains crew wages ($43 billion covering 1.4 million crew across the fleet). By comparison aggregate ship earnings for our cargo fleet fell from an eye watering $291 billion in 2008 to $123 billion in 2016!

Cutting The Fat…

One sector that has seen dramatic cost reduction has been offshore. Estimates vary, but 30% seems a reasonable rule of thumb for reductions in OPEX since 2014. While painful, this has been part of a process of making offshore more competitive against other energy sources (offshore contributes 28% of oil production, 31% of gas, and 16% of all energy) and one of the factors behind the increase in sanctioning of offshore projects.

Getting Smarter…

So shipping is one of the leanest industries around but is always under pressure to do more! It seems clear that squeezing cost in the traditional sense, offshore aside, will be pretty challenging — UK media reported on the docking of the 20,150 teu MOL Triumph, highlighting it was manned by only 20 crew! Getting smarter, collecting and using “big data” and technology and automation are all gaining traction. The industry’s fuel bill (accounted for outside of OPEX) is clearly a big target.

This will all require new technology, skills and perhaps new accounting approaches. Plenty of food for thought but it seems like just going on another severe diet won’t work this time. Have a nice day!

The introduction of new environmental regulations is leading the shipping industry to look for ways of reducing its emissions of harmful gases. This week we focus on two separate but related issues: the way in which vessels are powered, and the type of fuel that they use. New technologies are being adopted, with certain ship types leading the way…

Electric Therapy

The majority (96%) of active merchant vessels are powered by mechanical systems in which a form of fuel oil powers a main engine (usually a 2 or 4-stroke diesel) which is connected to the propeller. Most other vessels are “diesel-electric”, in which the power generated by the (4-stroke) main engine(s) is converted to electricity before being transferred to propeller(s) or thruster(s) via electric motors.

By optimising the loading of the engines, diesel-electric systems can lower fuel consumption and emissions. These systems are well established in sectors such as offshore, tugs and passenger, where manoeuvrability, variation in power demand and engine noise are important considerations. For larger cargo vessels, where demand for power is generally higher and more consistent, conventional mechanical systems remain more efficient and cost-effective. Our Graph of the Week shows that against a backdrop of reduced contracting in the larger cargo sectors, electrically-driven ships have assumed a greater share of the newbuilding market, accounting for 22% of reported newbuilding contracts so far this year.

Battery Charged

The next step for electric power may be more widespread adoption of batteries in main propulsion systems. There are 22 vessels in service and 14 on order that use batteries, mostly alongside either conventional diesel or dual-fuel generating sets. As well as reducing emissions when using battery power, these can enhance efficiency by optimising engine loads and transferring surplus power to or from the batteries as required. For smaller ferries intended for short routes, all-electric propulsion systems are feasible.

Gas Treatment

LNG has been identified as a cleaner fuel capable of reducing vessel emissions in line with new regulations. Clarksons Research’s World Fleet Register currently identifies 542 merchant ships in the fleet and on order capable of using LNG fuel. 351 of these are LNG carriers, which can use cargo boil-off to fuel a choice of turbine, dual-fuel diesel electric or dual-fuel 2-stroke main engines. In other sectors LNG fuel has taken longer to gain market share, but there are signs that where ship designs and the supply of bunkers allow, it is becoming more popular. Out of the 130 contracts recorded so far in 2017, 21 are for vessels capable of using LNG fuel. These include 4 Aframax tankers, the largest vessels other than LNG carriers to adopt dual-fuel 2-stroke engines.

More efficient power systems and cleaner fuels are two examples of how the shipping industry is responding to the challenges set by new environmental regulations. Alongside other developments in vessel design and operating practices, shipping is steering towards a more efficient and cleaner future. Have a nice day!
