#MarineNotice - Shell E&P Ireland Limited has begun a campaign of inspection of the Corrib Gas Field pipeline and associated infrastructure with repair and maintenance as required. Engineering tasks are also scheduled for well P3.

The near shore pipeline inspection was scheduled to commence in mid July and last for approximately 10 days. The offshore pipeline and subsea structure inspection along with the P3 work is due to commence in early August 2018 and last for approximately 14 days.

Visual and acoustic surveys will be conducted by means of sensors mounted on vessels and Remote Operated Vehicles (ROV) and cameras located on attendant survey vessels, ROVs and towed side scan sonar.

The near shore pipeline and umbilical sections will be inspected from the nearest point accessible inshore at high tide progressing to offshore until a suitable overlap with the offshore inspection is achieved.

The offshore inspection will commence at the Corrib field location and will continue towards shore until the vessel is required, on Marine Mammal Observer (MMO) advice, to relocate to the inshore inspection extent at safe navigation depth limit.

The vessel An Gearoidin (Callsign EIDL6) will undertake the near shore survey scope. All the equipment used will be vessel deployed. The Macbel and Blue Eagle will provide safety and welfare support to An Gearoidin.

The Siem Stingray (Callsign LAFP8) will undertake the deep water surveys and the subsea facilities maintenance and inspection. It will also carry out the P3 rectification work. All equipment used will be vessel and/or ROV mounted. All vessels will be listening on VHF Channel 16 throughout the project.

Full details of relevant co-ordinates and a map of the survey area are included in Marine Notice No 31 of 2018, a PDF of which is available to read or download HERE.

#MarineNotice - Shell E&P Ireland advises that it will commence rock placement works between two wells in the Corrib Gas Field before the end of this month.

These works, which are expected to be completed by the middle of August, come after a recent pipeline survey and inspection that included the installation of a replacement subsea control umbilical.

The latter requires the placements of rocks for protection within the 500m safety zone along the corridor between wells P1 and P5.

There will also be installation of rock protection/stabilisation at areas of known exposure or excess spanning along both the infield flow and control lines as well as the 20” pipeline and main control umbilical between the gas field and landfall at Glengad.

Works will be carried out by the DP Fall Pipe Rock Placement Vessel Seahorse (Callsign PCAP), which will be listening on VHF Channel 16 throughout.

Full co-ordinates of the rock placements are detailed in Marine Notice No 31 of 2017, a PDF of which is available to read or download HERE.

#MarineNotice - Shell E&P Ireland were scheduled to commence flowline installation works between two existing subsea wells at the Corrib gas field this week.

This work will be followed by placement of rock protection along the length of the exposed flowline between the two wells.

There may also be some additional rock placement along the pipeline corridor from the offshore field to the landfall at Broadhaven Bay.

The works, due to commence during this last week of July, are expected run for 30 to 40 days.

The first phase of works will all take place within the 500m Safety Zone surrounding the wells P2 and P5, and along the corridor between P2 and P5.

Carried out by the Skandi Neptune (callsign 2HMG8), the work involves the lay of a new flowline between the two wells followed by connection at each end and pressure testing.

Final seabed connections will be completed on the existing seabed control umbilical followed by the commissioning of the P2 well control system.

This work is expected to be completed by mid August, after whic the Nordnes (callsign PHOG) will commence the second-phase rock placements.

The guard vessel Glomar Arctic (callsign H09083) will be on location in the Corrib Field for the duration of the project. Radio warnings will be given to all marine traffic in the
immediate area. All the vessels will be listening on VHF Channel 16 throughout the project.

#Corrib - A prime example of "how not to undertake a development" – that's how a new planning report by British engineers describes the Corrib gas field project off the Mayo coast, according to The Irish Times.

Two of the authors of the report from the British Institution of Civil Engineers say that had Shell and the State agencies responsible for the controversial gas pipeline taken a more democratic approach, the project may have avoided what's known as 'space shuttle syndrome'.

That's a term used to describe when large-scale projects go wrong, reflected in the Corrib situation, the authors allege, in a number of factors not least budget overruns that have cost Irish taxpayers some €600 million – and the conspicuous "conflict with the local community".

The Irish Times has much more on the story HERE.

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.
