OSV Market Report 2026

High AHTS spot rates and a small newbuilding pipeline remain central to the OSV market in 2026, but neither tells the whole earnings story. Our October review separates North Sea fixture prices from utilisation and distinguishes the broader OSV orderbook from the large-AHTS segment. The resulting outlook is selective: vessel capability, deployment region and paid working days matter as much as the headline day rate.

Research updated: 12 October 2026. Latest complete monthly rate observations verified here: September 2026. Orderbook observations have separate dates below; these are not live charter quotations.

AHTS spot rates: September 2026 North Sea comparison

Source: Seabrokers, Seabreeze September 2026, pp. 10–13. GBP per day; monthly spot averages. Changes calculated from the published monthly series. Vessel classes follow the source’s horsepower and deck-area categories.

Large-AHTS spot utilisation fell from 73% in August to 61% in September; the smaller class rose from 46% to 52%. Higher fixture prices therefore coexisted with substantial idle time. A monthly fixture average cannot be treated as revenue earned on every calendar day.

PSV rates and the limits of a regional benchmark

The PSV figures provide a separate supply-duty benchmark. Deck area and engine horsepower describe different vessel capabilities; neither should be silently converted into deadweight or bollard-pull categories. Nor should a North Sea GBP spot average be presented as a worldwide USD term-contract rate.

For commercial planning, the useful comparison is between contracts with similar duration, location and operating obligations. Mobilisation, fuel allocation, off-hire exposure and the interval between jobs can change the economics even when two quoted day rates look similar. Our reading is that stronger fixture prices alone do not establish a uniformly stronger ownership market.

OSV orderbook 2026: PSV and AHTS supply are different

Tidewater’s September 2026 presentation reproduces a Clarksons Research orderbook chart using July 2026 data. Its latest plotted values indicate approximately 6% for PSV orders as a share of the PSV fleet and roughly 4–5% for AHTS. These are chart-read estimates, not exact tabulated percentages or an October vessel count. The chart shows recovery from recent lows, while remaining far below the earlier construction cycle.

The large-AHTS segment needs a narrower qualification. In its 16 September announcement, 2020 Bulkers described the large-vessel market it was entering as having no orderbook. This is the company’s segment-specific assessment; its announcement does not supply a horsepower threshold that can be matched directly to Seabrokers’ rate categories. It does not establish zero orders across all AHTS or all OSVs. Source: 2020 Bulkers, 16 September 2026.

PSV deliveries are also tangible: Seabrokers reported Capital Offshore’s first delivery from a 12-vessel programme in September, with two more expected in 2026 and nine in 2027. Four programme vessels are enhanced MPSVs, so counting all 12 as conventional PSV orders would blur the categories. Source: Seabreeze September 2026, pp. 14–15.

These observations support limited renewal, rather than an absence of construction. A global orderbook ratio does not specify when ships become available in a particular basin. Delivery timing, contract commitments and vessel configuration determine how much competitive capacity actually reaches a local market.

Newbuild economics: an assumption set, not a yard quotation

Tidewater’s September model assumes a US$65 million European-built PSV above 900 m², 90% utilisation, a 13% cost of capital and a 20-year useful life. Under those assumptions, the model requires approximately US$44,000/day through the cycle to reach zero net present value, with a three-year construction lead time. This is management’s investment model, not a verified price quote for every yard or a forecast spot rate. Source: Tidewater, slide 18.

Our interpretation is that sustained employment and financing terms govern the ordering decision. A brief rate spike does not by itself justify a vessel whose construction and operating life span several market cycles. The same distinction matters when valuing existing tonnage: a spot-market headline should not be capitalised as permanent earnings.

Outlook: watch paid days alongside prices

For the next update, the clearest signals will be the direction of AHTS spot utilisation, the persistence of stronger PSV fixtures and actual deliveries against announced schedules. Rising rates alongside improving utilisation would strengthen the earnings case. Additional prompt tonnage or delayed offshore work could weaken it even while the global orderbook remains modest.
