Changes are taking place in the OSV market in the North Sea as the number of high-spec anchor-handling tug/supply (AHTS) vessels declines, partly because of demand elsewhere, partly because of a dearth of newbuilds, and partly because of a contraction in the number of owners of specialized tonnage
Figures provided by Maritime Strategies International (MSI) suggest that there are currently around 570 OSVs in Northwest Europe, and that the northwest European fleet – as with much of the global OSV fleet – is an aging fleet, with 55% of vessels more than 15 years old, and just 9% less than 10 years old.
MSI associate director Todd Jensen said this situation is unlikely to be helped by newbuilding activity, with many of the large OSVs under construction being built not for the North Sea but for the South American market, particularly Brazil, where Petrobras has been offering long-term contracts at attractive charter rates.
A significant volume of demand is coming from Norway, aided by Equinor’s strategy which includes a planned US$60Bn investment to drill 250 oil and gas exploration wells over the next decade. The goal is to maintain 2020-level production of 1.2M b/d through 2035. “This will support OSV demand – in particular AHTS vessels – due to increased floating rig activity, with Equinor set to use a mix of drillships and semi-submersible rigs,” Mr Jensen explained. In contrast, the UK’s oil and gas sector continues to stagnate with very little exploration activity planned and most OSV activity focused on ever increasing maintenance and decommissioning work.
As Hagland Shipbokers told OSJ, the number of vessels in the AHTS spot market in the North Sea has been declining steadily over the last decade. “Some assets have been scrapped, others, including capable assets specifically built for operations in the North Sea, are being repositioned, heading for more active markets such as Guyana or Brazil because of better rates and utilization,” said the broker. “In addition, vessel ownership is consolidating, there are fewer AHTS vessel owners, and this contraction in supply has resulted in an increasingly volatile spot market.
Hagland Shipbrokers said it has seen frequent rate spikes this year – to unprecedented levels – such as a fixture for Njord Viking to Equinor at NKr4M (US$42,000) in April 2026. This makes it much riskier for charterers to fix vessels at short notice. “Where possible, fixing vessels well in advance can greatly reduce uncertainty around rate levels,” said the broker.
Hagland Shipbrokers believes that with supply currently limited and often snapped up quickly for individual campaigns – such as the vessels taken by Adura for the Rosebank FPSO project in May – and with newbuilding levels remaining low, the AHTS spot market will remain strong but volatile, with rates periodically shooting up to extreme levels.
Record rates for anchor-handlers have been a feature of the North Sea OSV market in 2026, a trend that other brokers believe is unlikely to change, given the vessels’ scarcity. As Fearnley Offshore Supply senior market analyst Jesper Skjong told OSJ in late May 2026, the momentum behind rates shows no sign of abating. “In the AHTS vessel spot market, we continue to see sky-high day rates,” he explained, and “new all-time high records. What is more, the number of months in which the average day rate for vessels was above NKr1M (US$105,000) now exceeds seven, with rates recorded in March and April above even that level.”
As Mr Skong told OSJ, although a period like this, at such high levels, has never happened before, it is important to bear in mind that it is the dearth of supply that is the key driver, not least because the total number of anchor-handlers in the North Sea has not been as small as it is currently for several decades.
Whatever the cause, said Mr Skong, the fact of the matter is that the average day rates recorded in the spot market in April were the highest Fearnley Offshore Supply has ever reported, including a new rate record akin to that cited by Hagland Shipbrokers of NKr4M (US$425,000) a day for a single vessel. “While this particular fixture was the result of an urgent requirement hitting a market with just enough vessels able to cover it, it is a great illustration of the rather extreme supply and demand dynamics in the North Sea spot market,” said Mr Skong.
Equally as interesting as the very high day rates recorded recently – perhaps more so – are the lowest rate levels observed. “We recorded the lowest fixture levels in March, at around NKr800,000(US$85,000)/day, while the lowest reported rate in April was around NKr500,000(US$53,000)/day,” Mr Skjong told OSJ. “For reference, if we turn the clock back a year, the corresponding levels were NKr175,000 (US$18,500) and NKr250,000(US$27,000), respectively. That really underlines shipowners’ newfound confidence in the AHTS market going forward, as well as how finely balanced it is. Not much is needed for the market to move upwards, quickly.”
Also interesting in such a dynamic market is that although rates have increased significantly this year, the total number of fixtures has fallen by more than 25% compared to the same period in 2025. To underline this point, Mr Skjong highlighted the fact that a couple of moored semi-submersible drilling rigs both went off hire after completing contracts in the UK last summer, rigs that would otherwise have required a considerable number of vessel days throughout the year. As Mr Skong also explained, despite the supply side remaining muted, a low level of activity can still create volatility – April saw record high rates, but the momentum levelled off in early to mid-May, with only 10 fixtures, all of which were below the NKr1M (US$108,000) threshold. However, late May saw rates rise again, so that they averaged more than NKr1M over the course of the month.
Although the AHTS vessel segment has continued to see consistently high day rates, albeit with lower utilisation, owners of platform supply vessels (PSVs) had a much more uncertain start to the year, even though the spot market has also been experiencing a gradual reduction in supply, primarily due to vessels transitioning to long-term contracts or leaving the region.
Hagland Shipbrokers said activity in the spot market has been low compared to previous decades, and that most activity is centred around Norway where the political climate is more favourable to exploration and drilling activity than in the UK. “Unless political attitudes change, we expect demand levels to remain fairly constant, and rate levels relatively constant, if subject to seasonal variations,” it said.
