The shuttle tanker fleet consists of a relatively modest 88 vessels, but is of critical importance to the offshore story. The sector has always played a key role in exports from fields divorced from established pipeline infrastructure. As the move offshore into deeper and more remote areas gathers pace, shuttle tankers will be required to support production, particularly off Brazil.

Exponential Growth

The fleet has a long track record of steady growth (it was just 19 vessels at the start of 1989), and has recently undergone another expansion phase, growing from 65 vessels at end 2010 to 88 currently (up 35%). There are 8 vessels on order: until the contracting of three specialised Arctic units at Samsung in July, no orders had been placed since January 2013.

This might appear, on the surface, to be a sign of a fleet sector with muted demand growth prospects, particularly when considered in conjunction with the decade-long decline in North Sea shuttle tanker transportation evident in the Graph of the Month. However, the outlook is actually somewhat brighter. Brazilian usage has gradually increased year on year. Brazilian fields are expected to be at the forefront of the sixty potential field developments identified globally which are likely to use shuttle tankers.

There are now 25 likely future field developments offshore Brazil, which are expected to need shuttle tankers, and potentially add 1.5m bpd to shuttle tanker movements off Brazil. In the pre-salt areas, pipelines are often not feasible due to deep water and long distances to shore, so fields need shuttle tanker offtake from FPSOs.

The North Sea is an established shuttle tanker region, and now one with much activity under way to halt production decline. There are 9 future start-ups expected to require shuttle tankers, including Bream and Johan Castberg. These are expected to help shore up North Sea oil transportation on shuttle tankers to above 1m bpd in the medium term.

Fleet Consolidation

Recent years have seen the fleet become more consolidated. At the end of 2004 there were over 10 companies with just one shuttle tanker to their name but as of September 2014 there are just two companies owning only a single ship. Teekay Offshore and Knutsen NYK continue to account for a large portion of the fleet, owning 32 and 25 units each. This year alone, Knutsen acquired Lauritzen’s fleet of 3 ships: these were the first recorded shuttle tanker sales for over 5 years.

Tread With Caution

Of course, shuttle tankers are not immune to the usual cyclic problems of the offshore industry. In the past 18 months, delays in field start-ups in Brazil and the North Sea have led some companies to let charter options expire or fail to renew existing timecharters. This may limit ordering (typically orders are placed with an initial charter in mind). Over the longer term, however, further fleet expansion will be required to service additional demand. Whilst the graph no doubt shows the ‘best-case’ scenario, and some field start-up slippage will no doubt intervene, the shuttle tanker sector looks positioned for a relatively bright future.

‘Pre-salt’ is usually a term associated with Brazil, where giant offshore field discoveries in the Santos and Campos basins have been grabbing headlines since 2007. Now oil companies are looking across the ocean for their pre-salt game. Conjugate basins offshore Gabon, Congo and Angola could be as juicy as the Santos and Campos pre-salt plays have proved. Following a number of recent scores by Cobalt, Eni, Harvest, Maersk and Total, the hunt is on.

Gearing Up

As the Graph of the Month shows, 16 wells targeting West African pre-salt reservoirs have been drilled since start 2011 with a success rate of 75%: 9 offshore Angola, 6 off Gabon and one off Congo. Oil from West African pre-salt was in fact first found in 1968. Its prospective yield was not appreciated though, as only recently did seismic imaging become able to give an accurate picture of the pre-salt. The ultra-deepwater of Angola’s Kwanza Basin also inhibited pre-salt exploration before sixth generation floaters. But, as Brazil has shown, operators now have all the technology they need to pursue the pre-salt.

Hunting Elephants

Some 27 future pre-salt wells are reportedly planned by oil companies or are anticipated through to end 2015, as the Graph of the Month shows. Four of these wells have been spudded. Often smaller E&P companies play a vital role in opening up new frontiers. In West Africa though, supermajors and other large players are already loading up. Conoco has 4 planned wells; Repsol, 3; Eni, 2; Shell, 2; and Total, 2. Of the 27 wells, 70% are offshore Angola and will therefore be in water depths ranging from 800-2,000m. The remainder are to be spudded off Gabon, likely in water depths up to 300m. In either case, companies will be hoping to hit world-class finds, like Cobalt’s Cameia discovery, which is expected to be brought onstream at 80-120,000 bpd in 2017.

Fieldcraft

So, the West African pre-salt play is still in the early stages of exploration and appraisal. If it proves prolific though, and if operators can bring it to fruition, a pre-salt bonanza would more than offset production decline from West Africa’s mature fields. With less stringent local content requirements and more international oil company control, development may be less fraught than in Brazil. Cobalt have already announced plans for 3 multi-field pre-salt hubs centred around the Cameia, Lontra and Orca fields offshore Angola. Given that the average water depth of Angolan pre-salt wells is 1,274m, MOPU solutions are likely to be favoured. The previous caveats noted, the FPSO ordering boom in Brazil could be replicated in Angola, which already accounts for 23% of world FPSO deployment (second to Brazil). In the shallower waters off Gabon, fixed platform solutions are probable, if finds reach the development stage.

In the near term then, the pre-salt safari offshore Africa looks to be an exciting campaign, with potential to generate even more interest in the region and hence opportunities for survey vessel and rig owners. Out towards the end of the decade, Angola could be the new Brazil, with pre-salt development contracts abounding.
