#CorkHarbour - An unusually high concentration of Mainport Group vessels among them a seismic-survey ship made a maiden Irish port of call to her owners homeport of Cork Harbour this morning, writes Jehan Ashmore.

Afloat had monitored the arrival of Mainport Pine, the most modern of the Cork based company fleet that docked just before 09.30hrs. Mainport Pine of 1,659 gross tonnage was delivered in 2014 and is the second of a pair of commissioned Malaysian built seismic-survey vessels.

These high-tech sophisticated vessels collect information about the subsea and so are vital for the oil and gas industry. The pair are used on the charter market by the exploration /energy companies.

Almost a year ago Afloat reported on sister Mainport Cedar completed in 2013, had previously also made a homecoming debut to Cork.  At the time the vessel was undergoing maintenance in between a repositioning voyage that led to a contract for the oil industry based in the Gulf of Mexico.

Mainport Pine had departed Bergen, Norway and Afloat yesterday had also tracked the ship while offshore of Wicklow Head when bound for Cork.  It was at the city's central quays that this morning saw the ship berth astern of a fleetmate, Mainport Kells. This seismic-chase vessel is designed to intercept any approaching vessels which could damage cables being towed or installed on the seabed.

The pair are togther berthed at North Custom House Quay.

Downriver one of Mainport's tugs Celtic Isle which in recent years was transferred from Shannon Estuary operations at the Port of Foynes, is berthed at Cork Dockyard.

Asides towage duties, Celtic Isle is employed on serving the requirements of the Kinsale Gas Field along with Ocean Spey which was acquired last year. This standby and supply vessel with handling handling capacity is this morning offshore of the two gas platforms rigs in the Celtic Sea.

#PORTS & SHIPPING - Cork based marine services company, Mainport is investing $36 million (€27.6 million) to build three supply vessels which will support seismic survey ships searching for oil and gas deposits.

The bulk of the financing for the construction of the newbuildings has been provided by Dutch bank ABN Amro, with a syndicate of Irish investors assembled by Westboro Finance in Cork providing $5 million in mezzanine, or short-term, financing.

The three ships, which will provide support services for an unnamed client carrying out off-shore seismic surveys around the world, are being constructed at Shin Yang Shipyards in Malaysia, and will be delivered in mid-2013.

The Half Ton Class was created by the Offshore Racing Council for boats within the racing band not exceeding 22'-0". The ORC decided that the rule should "....permit the development of seaworthy offshore racing yachts...The Council will endeavour to protect the majority of the existing IOR fleet from rapid obsolescence caused by ....developments which produce increased performance without corresponding changes in ratings..."

When first introduced the IOR rule was perfectly adequate for rating boats in existence at that time. However yacht designers naturally examined the rule to seize upon any advantage they could find, the most noticeable of which has been a reduction in displacement and a return to fractional rigs.

After 1993, when the IOR Mk.III rule reached it termination due to lack of people building new boats, the rule was replaced by the CHS (Channel) Handicap system which in turn developed into the IRC system now used.

The IRC handicap system operates by a secret formula which tries to develop boats which are 'Cruising type' of relatively heavy boats with good internal accommodation. It tends to penalise boats with excessive stability or excessive sail area.

Competitions

The most significant events for the Half Ton Class has been the annual Half Ton Cup which was sailed under the IOR rules until 1993. More recently this has been replaced with the Half Ton Classics Cup. The venue of the event moved from continent to continent with over-representation on French or British ports. In later years the event is held biennially. Initially, it was proposed to hold events in Ireland, Britain and France by rotation. However, it was the Belgians who took the ball and ran with it. The Class is now managed from Belgium.
