Rapid crew transportation for offshore Wind Farms

The demand for rapid crew transportation to and from wind farms, combined with the increasing distances between the wind farm arrays and the shore has resulted in the design and build of larger and faster crew transfer vessels and workboats. With work boat catamarans now averaging 16-20 metres, and sometimes up to 28 metres long, cruising speeds can be as much as 25-30 knots, and with the boats operating on 24/7 schedules, reliability is paramount.

Marine exhaust specialist Halyard says this trend for large, fast and highly utilised vessels has resulted in the company developing robust exhaust systems. These are designed not only to withstand the engine’s extreme working conditions, but also to reduce noise and vibration on board, helping to ensure crew and passenger comfort.

A recent example is South Boats Special Projects offshore wind farm crew transfer vessel ‘Iceni Pride’. This South Catamaran 13m Rapid Response Vessel is being used by Iceni Marine Services for Scottish and Southern Energy on the Greater Gabbard Offshore Wind Farm project. Halyard was commissioned by South Boats Special Projects to design, manufacture and install the exhaust system for the twin Caterpillar C9 ACERT 510hp diesel engines, and Hamilton HJ364 water jet units. The system not only ensures the vessel can maintain her cruising speeds of 25 knots fully laden, but also the frequently-used sprint speeds of more than 30 knots. The system also reduces through hull and engine noise, as well as vibration on board. This is particularly significant as Iceni Pride will be used for VIP transportation, as well as for standard crew transfer duties.

Portsmouth-based Halyard appoints Value Engineer

Local marine equipment manufacturer Halyard, which is headquartered in Salisbury and has manufacturing sites at Portsmouth and Bournemouth, has appointed a Value Engineer. The role is focused on improving manufacturing techniques and reviewing materials allowing Halyard to improve quality whilst reducing cost.

Halyard produces bespoke and custom designed specialist exhaust systems for vessels ranging from multi-million pound super yachts to commercial craft and their products are renowned for reliability and every day use in some of the world’s toughest seas. The companies products are required to meet increasingly rigorous and legislated quality standards from design through to installation.

The Value Engineer position has been created at the company’s GRP manufacturing site in Portsmouth where silencers up to 1 meter in diameter are made. After advertising the post the company selected Paul Drackett, who joined the company ten years ago aged 21.

Paul says he was delighted to be promoted to this new role. “I started with Halyard in 2001 working on the shop floor as a laminator, and I’ve worked my way up to Leading Hand overseeing some of the manufacturing team. Now this new role takes me from the manufacturing side to management, ensuring that at every stage from goods inward to dispatch we maintain the highest quality standards, looking at the processes and materials, and matching the design requirements to the finished product.”

Paul says his experience of working on the shop floor has definitely helped in his new role. “I can interpret the drawings we receive and understand fully the manufacturing processes required. The new role creates an effective bridge between design and production, and will help us to produce more complicated and sophisticated products at this site.”
