ScottishPower Renewables awards VOS long-term ERRV charter for East Anglia TWO and THREE

# What happened ScottishPower Renewables has awarded Aberdeen-based Vroon Offshore Services (VOS) a long-term charter to provide emergency response and rescue vessel (ERRV) services during the construction of the East Anglia TWO and THREE offshore wind farms off the Suffolk coast. The agreement is valued at more than £7 million and marks VOS's first long-term commitment to the offshore renewables sector.

# Where the vessel will operate The chosen vessel, VOS Traveller, will be based out of Lowestoft port. The ship will provide on-site ERRV coverage through the construction phase of both wind farms, remaining on continuous standby to respond to incidents and to support safety and logistics for construction teams offshore.

# Crew and rotations VOS Traveller will operate with a 24-strong crew on a 28-day rotation. That sets the staffing and availability model: continuous 24/7 standby with crews rotated roughly monthly to maintain operational readiness while managing fatigue and personnel logistics.

# ERRV capabilities and duties VOS Traveller is a purpose-built Class B ERRV, built in Stellendam, the Netherlands, in 2008, and measures 48.2 m in length. Reported operational capabilities and duties include:

• 24/7 continuous standby and safety cover for construction activities.
• Search-and-rescue support able to provide a place of safety within 20 minutes.
• Recovery equipment including two fast rescue craft, a Dacon scoop, and a heavy-duty rescue basket.
• Onboard medical treatment facilities for casualty care prior to transfer.
• Advanced collision-avoidance surveillance and radio watchkeeping.
• Field logistics support and offshore environmental monitoring.

These capabilities are tailored to the practical needs of construction sites where personnel and vessel traffic require immediate emergency response and medical readiness.

ScottishPower Renewables' Managing Director for Offshore, Ross Ovens, welcomed VOS into the East Anglia supply chain and emphasized safety for offshore construction personnel. ScottishPower stated that the two projects together will produce enough green electricity for more than 2 million homes, support thousands of jobs during construction and operation, and contribute more than £3 billion to the UK supply chain.

VOS Managing Director Stuart Thom described the contract as a major milestone for the company, noting it is VOS's first long-term ERRV commitment in the renewables sector and expressing a focus on collaborating to maximise safety for personnel during construction.

# Why it matters

# Practical implications Operators, contractors and supply‑chain organisations involved in East Anglia TWO and THREE will coordinate with the ERRV team for emergency procedures, muster points, casualty transfer protocols and environmental monitoring tasks. The Lowestoft base will also serve as a local logistics hub for rapid deployment of the vessel and rotation of the 24‑person crew.
