Strong OSV market fundamentals underpinned surging M&A activity in Q2 2024, led by merger deals from DOF Group and Cyan Renewable
Confident in the strength of that the current offshore energy upcycle, legacy OSV owners and new investors are scouring the market for quick opportunities to expand and upgrade their fleets. While some new players, such as the Evangelos Marinakis-backed Capital Offshore, are making splashy investments in newbuilds, others are looking to quickly add high-spec vessels to their fleets through M&A deals to take advantage of surging day rates.
Q2 2024 saw a number of these, none bigger than DOF Group’s bid to scoop up Maersk Supply Service (MSS) in a US$1.1Bn cash-and-stock offer. It is the largest M&A transaction in the sector in a decade.
The transaction, which is subject to customary approvals, does not include the Danish OSV owner’s offshore wind installation business, which will remain with AP Moller Holding as an independent offshore maritime company named Maersk Offshore Wind, nor does it include MSS’ operations in Brazil. Additionally, AP Moller Holding gains 25% of the share capital in DOF.
The Oslo-listed DOF Group is clearly bullish on the opportunities available in the deepwater and subsea offshore oil and gas and offshore wind markets. It says the deal will make it the world’s largest owner of construction support vessels (CSVs) and high-end anchor-handling tug supply (AHTS) vessels. The pro forma combined owned fleet would be 65 OSVs: 33 CSVs, 25 AHTSs, six platform supply vessels (PSVs) and one cable-layer. Making the deal sweeter is the relative youth of the MSS fleet, which has an average age of 8.5 years. With the acquisition, DOF would be able to turn back the clock by a year, lowering the overall fleet age for its subsea and AHTS vessels from 11.7 years to 10.7 years.
Fearnley said the offer showed “DOF is more willing to acquire modern high-specification assets with cash flows today as opposed to engaging on a major newbuild programme with high capex and limited earnings in the medium term, which we view as a positive sign for the fleet balance going forwards.” Additionally, the shipbroker said the financial backing structure for the acquisition suggested “there is a strong belief in a longer-term cycle,” noting that a DOF IPO was executed at Nrk28 per share only a year ago.
Financing for the acquisition includes US$500M in debt from a consortium led by Norwegian financial group DNB combined, with existing shareholders such as the John Fredriksen-led Seatankers, to provide US$30M in equity at close to Nrk100 per share.
The billion-dollar-plus deal is reflective of how the fortunes of the OSV sector and offshore energy business have changed for the better in the past seven years. In Q4 2017, MSS had been classified as a discontinued operation and held as an asset for sale by then owner AP Moller-Maersk. In March 2019, AP Moller-Maersk attempted to sell MSS, but its board shelved the idea because of challenging market conditions but decided to reclassify the OSV unit back to continuing operations. For the financial year 2018, MSS had reported a revenue of US$263M and an EBITDA of US$3M, with a negative free cash flow of -US$316M due to costs associated with four newbuildings. Those newbuilds were part of a 10-ship programme that included six M-class AHTSs and four I-class subsea support vessels (SSVs).
In 2023, AP Moller–Maersk announced the divestment of Maersk Supply Service under a US$685M agreement with privately held investment firm AP Moller Holding.
Another big deal
Another acquisition was swung in the quarter by Singapore-based Cyan Renewables for ASX-listed MMA Offshore. The private-equity-backed offshore energy vessel owner had to sweeten its offer to Aus$1.07Bn (US$725.3M) to gain the approval of the majority of ASX-listed MMA Offshore shareholders. Cyan intends to retain MMA Offshore’s workforce and to utilise and grow the company’s expertise, assets and operating model to expand further into offshore wind support services while continuing to provide a comprehensive suite of marine and subsea services to its existing clients in the offshore energy and wider maritime industries.
MMA Offshore controls a fleet of 20 vessels, includes AHTs, AHTSs, PSVs and multi-purpose support vessels. In its half-year results (reported as of 31 December 2023) for financial year 2024, MMA Offshore reported an average fleet utilisation of 83%.
This is the second acquisition this year by the fast-charging Cyan Renewables. In January, it acquired a 75% interest in UK-based OSV owner Sentinel Marine, which controls a fleet of 13 multi-role field emergency response and rescue vessels, with an average age of about 7.6 years.

Other M&A deals
Several smaller M&A deals were struck in Q2 2024, creating some consolidation among Norwegian and Dutch vessel owners. Havila Group closed on Volstad Maritime, changing its name to Havila Subsea & Renewables. Subsea services specialist N-Sea acquired fellow Dutch competitor Geo Plus, and its fleet of six survey boats. And finally, wastewater treatment specialist Soiltech will merge with Oceanteam to form the public limited liability company Soiltec ASA. No shipping assets are involved in the merger.
Norwegians Christian Sveaas and Kristian Siem finished their vessels-for-shares swap. Sveaas-led Sea1 Offshore sold nine OSVs to Mr Siem in exchange for his 35.7% shareholding and US$117.5M in existing debt assumption.
“There is a strong belief in a longer-term cycle”
Sea1 Offshore was formerly Siem Offshore before changing its name in May. Following the sale, Mr Siem will move his nine vessels into Siem Sustainable Energy, his new company.
After the transaction, Sea1 owns and operates a fleet of 17 vessels. But the company further manages 12 units, including the nine vessels taken over by Mr Siem.
One of the new players in the market, Pelagic Partners, has built on its investment in Golden Energy Offshore Services (GEOS), with the addition of two three-year-old LNG dual-fuel battery-hybrid PSVs to its portfolio. Pelagic Partners has joined with Borealis Maritime and Aurora Offshore in owning and managing two 2021-built sister ships, Aurora Coey (ex Viking Coey) and Aurora Cooper (ex Viking Cooper). Both PSVs are working in the North Sea market – Aurora Coey offshore Scotland with Harbour Energy and Aurora Cooper in Norway.
North Sea day rates
Day rates for AHTS vessels in the North Sea gradually increased in May and June. Fearnley reported day rates in May were about 15 to 18% lower than the same time last year, but still represented the second-best month in Norway so far this year, and the third best in the UK.
Average day rates in Norway ended the month with an average of just over Nrk600,000, while “the UK market was slightly disappointing with an average of £35,000 per day”, said the ship broker.
“The market saw several fixtures around and even above the Nrk1 million mark”
In June, average day rates in the UK North Sea increased to about £70,000, while Norwegian charterers paid almost Nrk800,000. “Towards the end of the month the market saw several fixtures around and even above the Nrk1 million mark,” said Fearnley. This was caused by “low availability of vessels due to many ongoing projects – of which several [are] taking longer than anticipated – and a high number of rig moves simultaneously [which] is always a good mix for owners,” explained the broker.
Batteries included
Overall, battery-hybrid PSVs fared well in fixtures during the quarter on the Norwegian continental shelf (NCS). Among those are two Vard 1 07 design diesel-electric-battery PSVs owned by Tidewater.
The two sister PSVs in question, Sygna Tide and Sun Tide, have clear deck areas of 1,140 m2, with propulsion power supplied by three Rolls-Royce Marine 2,460-kW C25:33L8ACD diesel gensets, supplemented by 500 kWh of battery capacity.
Equinor extended both PSVs by 12 months, with Sun Tide firmly fixed until July 2025 and Sygna Tide until September 2025. Both vessels have been working with Equinor, and its predecessor, Statoil, since they were delivered in 2014, according to Seabrokers.
Both sister vessels were acquired by Tidewater in its US$577M, 37-vessel purchase from Solstad Offshore. One result of that massive en bloc purchase was to make Tidewater the owner of the world’s largest fleet of battery-hybrid PSVs.
And speaking of the NCS and battery-hybrid vessels, Eidesvik Offshore’s PSV Viking Lady was extended in Q1 2024 by Aker BP until February 2026, while the company’s shipmanagement agreement with Deme for the subsea support vessel Viking Neptun was upped for three more years.
Eidesvik Offshore chief executive, Gitte Gard, said her company reported its “strongest Q1 result in seven years.” The Norwegian owner had fleet utilisation of 96% for Q1 2024, up from 81% for the same period last year. Quarterly revenue and EBITDA were Nrk183.4M (US$17.0M) and Nrk67.4M (US$6.3M), up from Nrk133.5M (US$12.4M) and Nrk27.8M (US$2.6M), respectively, from the same period in 2023. The EBITDA margin was 37%, up from 21% in Q1 2023. How did Eidesvik do it? Ms Gard said the company “capitalised on thriving markets across all its operating segments.” All of Eidesvik’s vessels are on long-term contracts, and its contract backlog of Nrk2,840.0 (US$246.5M) is at its highest level in nine years.
