What Leask Marine does
Leask Marine Ltd is a privately held, founder-owned marine services company established in 1985 and headquartered in Kirkwall, Orkney, with a secondary Welsh base at Pembroke Dock's Marine Energy Hub. The company operates a fleet of purpose-built multipurpose vessels — including the MV C-Trojan (Damen Multicat 3113 DP1, 30.17m), MV C-Fenna (Neptune Eurocarrier 2611, 26.48m), MV C-Horizon, MV C-Odyssey, MV C-Force, and MV C-Spartan — and offers an integrated service portfolio spanning vessel charter, commercial diving (including saturation diving with chamber and LARS), ROV operations, marine towage, marine salvage, subsea drilling, and marine construction (pier maintenance, civil/mechanical engineering, dredging, non-destructive testing). Leask Marine has developed proprietary technology, most notably the world's first Submersible Drilling Rig (a £1.5m SMART-grant-funded R&D project launched in 2019), and holds rare multi-class-society approved service supplier status (DNV-GL, Lloyds Register, ABS, RINA) for in-water surveys.
The company serves marine renewable energy developers (wave, tidal, offshore wind — including floating offshore wind), ports/harbours and government bodies, aquaculture operators, and international offshore contractors across Europe and selectively in North America. Notable enterprise relationships include NKT HVC (six-month nearshore campaign at Moray East Offshore Wind Farm), DeepOcean (anchor handling at Walney), Magallanes Renovables (ATIR 2MW tidal platform at EMEC), EMEC (long-standing host-site services), EMEC/Instream Energy Systems (first tidal platform built in Orkney), and Atlantis Resources (Meygen subsea cable route). Go-to-market is direct enterprise sales led by the Managing Director, Operations Director, and Commercial & HSEQ Director, supplemented by an active presence at industry conferences (All-Energy, Seawork, Offshore Wind Conference) and a track record across 32 international wave & tidal developers from 15 countries.
Revenue is generated on a project-by-project, time-charter, or bespoke contract basis with no public pricing tiers; multi-million pound contracts are referenced but specific figures are not disclosed. The 2025 funding round (Royal Bank of Scotland, £200,000) and 2023 UK Department for Transport award (£207,511) point to modest balance-sheet scale, while a new head office and yard in Orkney and the 2026 launch of the C-Trojan indicate a deliberate capacity-expansion phase heading into the European offshore wind build-out cycle.

Leask Marine competitors and assessment
Company assessmentDirect peers
- Briggs Marine: UK-based marine services contractor providing vessel charter, commercial diving, salvage, and subsea services to ports, harbours, and offshore energy clients. Highly comparable in scope, scale, and customer base to Leask Marine, with similar geographic focus on UK coastal and offshore markets.
- Sentinel Marine: UK-based operator of offshore support vessels serving the oil & gas and offshore wind sectors with anchor handling and supply vessels. Comparable in fleet composition and customer overlap with Leask Marine's anchor handling work at Baltic 1 and Walney Extension.
- North Star Shipping: UK-headquartered offshore vessel operator with significant new-build SOV/CSOV fleet serving European offshore wind farms. Comparable in serving the same offshore wind customer base, though at greater scale and with newer purpose-built tonnage than Leask Marine.
- CWind: Part of the Global Marine Group, CWind provides crew transfer vessels and services to the offshore wind sector across Europe. Directly comparable to Leask Marine's offshore wind service offering, particularly around nearshore and turbine maintenance operations.
Broad incumbents
- DOF Subsea: Global subsea services provider offering ROV, diving, survey, and vessel services to offshore energy markets. Overlaps with Leask Marine's diving, ROV, and survey capabilities, though at substantially greater scale and global reach.
- Van Oord: Dutch marine contractor with offshore wind installation, cable lay, and dredging capabilities across European markets. A direct competitor for nearshore infrastructure and cable installation work, though operating as a major EPC contractor rather than a specialist services provider.
- MMA Offshore: Australian-headquartered marine services company providing vessel charter, subsea, and offshore support across Asia-Pacific and beyond. Comparable in service mix (vessel charter, diving, subsea, ROV) though operating across different geographies.
- James Fisher and Sons: Listed UK marine services group offering subsea services, vessel charter, diving, and renewable energy support across global markets. Overlaps with Leask Marine across diving, subsea, and offshore wind, but operates at significantly larger scale with broader geographic and product reach.
- Solstad Offshore: Norwegian global offshore service vessel owner with deep North Sea and renewables presence. Competes with Leask Marine in anchor handling and offshore support but operates a fleet of 50+ vessels across global markets.
- Vroon Offshore: Dutch offshore vessel operator with substantial subsea support, anchor handling, and SOV fleet serving European offshore energy markets. A direct competitor for offshore wind charter work but materially larger and more diversified than Leask Marine.
