#POWER FROM THE SEA - This morning the wind farm turbine installation vessel Sea Energy, departed Wicklow Bay having spent over a fortnight based in Wicklow Port, where her Danish crew celebrated Christmas Day, writes Jehan Ashmore.

The Esbjerg registered vessel operated by A2 Sea, arrived in the week before Christmas to work at Airtricity's Arklow Bank Wind Farm, but the nature of the work was based on internal operations only at the seven turbine facility, which each structure scaling to a height of over 70 metres / 240 feet.

Upon completion of her work, she returned to Wicklow where her crew spent the festive season in port with a Christmas tree complete with  lights! at the bow.

She remained in the harbour into the New Year and during the recent spate of heavy weather until finally departing yesterday on Little Christmas, where she overnighted in the bay.

With four towering supporting jack-up legs each 32 metres  high, this enables her to carry out offshore crane operations with greater control. In addition the vessel is raised completely above the water to gain elevation to assist mounting the pre-assembled wind-turbine components from her deck cargo.

She can work in waters of up to 24 metres and as she rests on the sea-bed this provides a more stable working platform.

Sea Energy presented a distinctive profile while in port as she 'sat' close to the Packet Quay, as her jack-up legs make mooring ropes redundant.

The quay is the main commercial quay and during this week she vacated the berth to allow regular caller Scot Isles (2001/2,595grt) which arrived with a cargo of sawn packaged timber products from Scandinavia. Owned by Scot Line, the vessel remained in the port for two days and then departed for Warrenpoint.

The Wicklow Port Company also specialise in dry-cargoes, lead, and scrap-metal as previously reported, to read more click HERE.

It is somewhat unusual for vessel movements in Wicklow to berth outside the harbour piers, as in the case with Sea Energy.

She shifted berths to the seaward side of the West Pier and again she sat with jack-legs lowered in water depths of six metres, leaving a clearance of around two metres below the keel.

Although Arklow is closer to the wind-farm than Wicklow, Sea Energy's 3,332 gross tonnes is too large to be accommodated as the port on the River Avoca has a has lower water depth.

Irish Sailing Classes and Association – There’s no shortage of one-design classes from which to choose and each gives its enthusiasts great competition, fun and camaraderie, writes Graham Smith in this review of the classes. 

One-design racing is where it all starts. It is, after all, where all the top sailors earned their stripes, battling away for line honours without a thought for a handicapper’s calculator wiping away a hard-fought victory!

Indeed, you could count on less than one hand the number of top Irish sailors who didn’t cut their teeth in a one-design dinghy! Just think of Cudmore, Barrington, Watson, Wilkins, Hennessy and Dix to name a few and you realise that they honed their skills in everything from Enterprises to Lasers and a lot in between.

At present count, there are a little over 30 one-design classes in Ireland, split almost evenly between dinghies and keelboats, a statistic which might raise a few eyebrows. They range from the long-established Mermaids, IDRA14s and Dragons to the newer additions like Fevas, Topaz and RS Elite. They all fill a particular need and give their owners and crews considerable enjoyment.

Many have attracted their World or European Championships to Irish waters over the years and while 2009 is notable for a lack of such events here, the following year will see the Etchells Worlds at Howth and perhaps a few other international regattas too.

In addition to the review, we asked each class to complete a questionnaire giving details of their fleet numbers, whether they were on a growth pattern or holding their own, so we could highlight those ‘on the up’ and those remaining static in terms of numbers. The older traditional designs, as you might imagine, fall into the latter category, although that’s not a negative!
