CTV Careers: How to Build a Career Skippering Crew Transfer Vessels in Offshore Wind

Why CTV Is One of the Fastest-Growing Maritime Career Paths in the UK

While deep-sea shipping gets most of the attention in maritime careers coverage, one of the most significant growth areas for UK seafarers right now is happening in waters much closer to home. Crew Transfer Vessels — the fast catamarans and monohulls that transport offshore wind technicians to turbine foundations and back — are in high demand, their operators are expanding fleets rapidly, and experienced CTV skippers are genuinely hard to find.

The UK has the largest installed offshore wind capacity in the world, with major developments including Hornsea (the world’s largest offshore wind farm), Dogger Bank, East Anglia Hub, and numerous others in various stages of construction and operation. Each operational turbine requires regular access for inspection, maintenance, and repair. Each maintenance crew accessing those turbines travels by CTV. The maths is straightforward: more offshore wind means more CTVs, more skippers, and more career opportunities for the right candidates.

What a CTV Actually Is

A Crew Transfer Vessel is typically a 20-26 metre aluminium or composite catamaran, capable of 25-30 knots in suitable conditions, designed specifically for the task of approaching offshore wind turbine transition pieces (the lower section of the tower just above water) and “landing” technicians safely onto the turbine access platform.

The defining characteristic of CTV operation is the approach manoeuvre: the vessel holds its bow against the turbine landing pad using continuous thrust, often in 1-2 metre significant wave height, while technicians step from the bow onto the access ladder. This requires precise ship handling, good situational awareness, and the kind of boat sense that develops over time — it is not purely a qualification issue. The best CTV skippers are excellent boat handlers first, and everything else follows.

CTVs typically carry 6-24 technicians plus crew, operate from nearby port bases (Grimsby, Blyth, Barrow, Great Yarmouth, and other offshore wind gateway ports), and work on a shift pattern that typically provides better work-life balance than deep-sea watchkeeping schedules.

Qualifications: What You Actually Need

The Boatmaster’s Licence (Coastal)

For most CTVs operating within UK coastal waters, the MCA Boatmaster’s Licence — specifically the Coastal endorsement — is the appropriate qualification for skippers. The Boatmaster’s Licence operates at three levels:

• Inland Waterways — rivers and canals; not relevant for offshore wind
• Tidal Waters — estuaries and tidal rivers; limited application for offshore CTV
• Limited and Coastal — the relevant qualification for UK offshore wind CTVs operating within Category 2 and Category 3 areas (up to 60 nautical miles from a safe haven)

The Boatmaster Coastal qualification requires demonstrated practical competence in coastal navigation, vessel handling, stability, stability information, and emergency procedures. MCA approval of the licence is through an oral examination and assessment of qualifying sea service.

STCW Basics

In addition to the Boatmaster’s Licence, CTV crew will need the standard STCW Basic Safety Training package (BST), a current ENG1 medical certificate, and for some roles, a Proficiency in Survival Craft (PSCRB). GWO (Global Wind Organisation) Basic Safety Training — which covers working at heights, fire awareness, first aid, manual handling, and sea survival specific to offshore wind — is also typically required by wind farm operators and is worth completing before your first CTV role.

Pathways to CTV Skipper

There are two main entry routes:

Via the workboat/commercial vessel pathway: Build sea time on harbour craft, pilot boats, survey vessels, or ferries. Accumulate qualifying sea service in command or as mate. Sit the Boatmaster Coastal oral. This is the most direct route for seafarers already in smaller commercial vessels.

Via RYA Yachtmaster: RYA Yachtmaster Offshore or Ocean certificate provides an alternative pathway, with MCA conversion available. A significant number of CTV skippers in the UK came through the RYA route, particularly those with extensive sailing or motor cruising backgrounds.

The J+1 Requirement and Crew Roles

Most CTVs operate under a “J+1” minimum crewing requirement — one Skipper (the qualified Boatmaster) plus one deckhand. The deckhand role on a CTV is an excellent entry point into the offshore wind sector: you develop boat-handling awareness, gain qualifying sea service, and build the turbine access experience that wind farm operators value.

Deckhand qualifications typically require STCW BST, ENG1, and GWO BST. Some operators will train from scratch for candidates with a strong practical maritime background (dinghy sailing, powerboat, harbour experience).

Operators Hiring in the UK

The main CTV operators active in UK waters include:

• Windcat Workboats — one of the largest European CTV fleets; strong UK presence
• Seacat Services — UK-based, operating at multiple North Sea and Irish Sea wind farms
• Viking Sea Tech — Norwegian-owned but with significant UK fleet
• SOL Group — Danish owner, UK operations
• Norwind Offshore — Norwegian CTV operator with UK expansion
• Bernhard Schulte Offshore — Multinational, with dedicated CTV fleet

Beyond these dedicated CTV operators, major offshore wind developers including Ørsted, Vattenfall, and SSE Renewables manage their own or contracted CTV fleets through their Operations & Maintenance contracts. Getting onto a wind farm O&M contract — even as a technician transport operator rather than a turbine technician — provides access to a stable, long-term employment pipeline.

Work Pattern and Lifestyle

One of the most frequently cited advantages of CTV careers, compared to deep-sea or offshore support vessel roles, is the work pattern. Most UK CTV operations work on a 2-weeks-on/2-weeks-off rotation or similar, based from a fixed port. You sleep ashore, have regular time at home, and the operational day is structured around daylight and weather windows.

For seafarers with families or other commitments ashore, or for those who want the nautical side of the job without multi-month deep-sea contracts, CTV represents a genuinely attractive career structure. Pay for experienced CTV skippers is competitive with similar-sized commercial vessel roles, and senior positions with larger operators include responsibility for fleet operations, technical oversight, and cadet development.

The Workboat Association’s CTV Workgroup — which met in London in September 2026 — continues to develop industry guidance and best practice for the sector. If you are building a CTV career, the WA is the relevant professional body to follow for regulatory updates and networking.
