In the broader context of firm global LNG demand growth, Australian offshore gas mega-projects have been a significant feature of the offshore sector for the last decade, driving innovation (think Prelude FLNG) and yielding rapid production growth. There are also a few projects projected to push output even higher in the short term, though against this backdrop, there are some uncertainties in the longer term.

January 26th is Australia Day, a chance to celebrate all things Australian: vegemite, sporting prowess, BBQs, surfing, unusual (and frequently lethal) wildlife, digeridoos, Uluru, Kylie, Mad Max and so on. But from a shipping and seaborne trade perspective, perhaps the most relevant features of Australia are literally from the land ‘down under’, namely iron ore, coal and natural gas.

Indian offshore fields used to be the main source of the natural gas consumed in India’s rapidly growing, energy-hungry economy; now however, it is LNG imports. This recent change is largely due to a decline in the country’s offshore gas output. But as part of a drive to reduce reliance on energy imports, the Indian government has been introducing policies designed to raise offshore gas production once more…

A key driver of seaborne trade growth over the last two decades has been the spectacular economic rise of China. With the Chinese economy likely to gradually mature, the idea of the “next China” for shipping has been often discussed, and India has often been put forward in this context. There are many factors to consider, but in any evaluation of this possibility, trends in India’s energy sector are highly significant.

The development of the global merchant fleet is affected by a very broad range of interwoven supply and demand factors, including shipping and commodity cycles, investor sentiment, regulatory concerns, yard capacity and so on. Another factor is shore-side infrastructure projects, which can be tricky to disentangle from the wider web, though this influence is a little clearer on, for example, the LNG carrier sector…

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!

SIW1266:Graph of the Week

Natural gas is set to account for an increasing share of the global energy mix in coming years, with gas consumption growing by an average of around 1.5%-2% a year out to 2040, according to energy forecasting agencies such as the IEA. And based on recent trends, if the consensus views on natural gas prove accurate, the implications for the offshore and LNG carrier fleets are likely to be significant.

Stepping On The Pedal

In 2016, global natural gas demand stood at an estimated 347bn cfd, up by 24% on the 280bn cfd consumed in 2006. Demand for natural gas in recent years has been driven by industrialisation in developing economies (Chinese gas demand, for example, grew at a CAGR of 13% in 2006-16) and environmental concerns the world over. Historically, the majority of trade in natural gas has been by pipeline, for instance from Eurasia to Europe. In 2015, pipelines still accounted for 68% of natural gas volumes moved globally.

However, liquefied natural gas (LNG) has become an increasingly important form in which gas is traded, even given the costs of complex liquefaction and regasification facilities. Over 50% of existing nameplate liquefaction capacity at LNG export terminals (349mtpa globally) has come online since 2005. As a corollary, from start 2006 to start March 2017, the LNG carrier fleet increased from 193 to 479 vessels and tripled in total capacity to 70.2m cubic metres of LNG.

Shifting It Up A Gear

Growth in the seaborne LNG trade is in turn closely linked with growth in offshore gas production, as major LNG exporters such as Qatar and more recently Australia use offshore gas fields to provide feedstock to LNG trains. Qatar accounted for 30% of LNG exports and 22% of existing liquefaction capacity in 2016, all fed via offshore gas, mostly from the giant North Field. In 2006, offshore fields accounted for 28% of global gas production and by 2016, 31%. This is set to rise to 32% (119bn cfd) in 2017, mainly due to field start-ups off Australia that are to feed LNG projects like Wheatstone. Finding, developing and supporting offshore gas fields on Australia’s NW Shelf has created demand for a range of vessels from the offshore fleet of over 13,500 units.

More Gas In The Tank

The exploitation of these remote reserves has also spawned the FLNG concept – vessels that can be used to exploit otherwise stranded gas. The LNG markets are clearly challenged at present but in the long term, planned FLNG projects in Australia, Mozambique, Tanzania, Mauritania and other areas could potentially sustain offshore gas production growth. Another major source of gas production growth has been the US shale gas sector, where production rose from 4bn cfd in 2007 to 48bn cfd in 2016. The US accounts for over 50% of liquefaction capacity under construction (while some planned projects entail liquefaction of shale gas on near-shore FLNGs) and is set to become a major LNG exporter in coming years.

So offshore gas production has grown as a share of total global gas production, as has US shale gas. Both trends can create opportunities for LNG and offshore vessels. And if, in line with consensus expectations, gas continues to grow as a share of the energy mix, then these trends may have a long and interesting road ahead.
