FEATURE WELL INTERVENTION

Just as the oil and gas industry was starting to get back on its feet, Covid-19 and plummeting oil prices have affected the market across the board, including well intervention. But players in this space are optimistic, with new vessels and more compact intervention systems being planned and hopes that production enhancement will be an easy win for operators post-Covid, reports Elaine Maslin. he light well intervention (LWI) segment – from ves- spent most of its recent working life as a walk-to-work vessel in sels, rather than rigs - struggled in the downturn, the offshore wind market, despite still being equipped with a says Catherine MacFarlane, subsea analyst, Energy, at tower on board, says MacFarlane.

Covid-19, 2020 was showing some very modest rate increases and a stabilizing market, she says.

Indeed, 2019 and into early 2020, riserless light well in- tervention (RLWI) activity had been steadily growing, says

The UK and Norway have been RLWI heartlands, with fve

RLWI vessels in operation, but other regions had picked up too, says Olsen, such as West Africa, where riserless interven- tion operations (hydraulic and mechanical) amounted to more than 300 days – up from about 100 days per year – with three major oil companies performing multi-well campaigns across three countries at the same time. Indeed, in February, Ocean- eering inked a signifcant RWLI services contact with BP over

Blocks 18 and 31, offshore Angola, running from Q2 into late

Fall. The Gulf of Mexico has also been busy, notes Olsen.

The current outlook, however, isn’t so great. “Operators very rapidly froze, delayed or cancelled operations, in an ef- fort to preserve cash,” Olsen says.

Unlike subsea construction vessels, there are few other mar- kets for dedicated LWI vessels to seek refuge in, says MacFar- lane, and competition from rigs could be hard for semisub- mersible units.

Units ordered in past years also remain idle. Newbuild semi- submersible intervention unit Etesco Interventor remains at the Dalian yard, China, after Petrobras and Etesco reached an agreement to cancel its charter in 2017, says MacFarlane. The

PaxOcean yard is also still home to the newbuild semi Derwent, following the termination of a shipbuilding contract with Hal- lin Marine in 2014. To date, the Derwent is yet to fnd a buyer or work. At the same time, the Skandi Constructor, which was
