#MarineNotice - Providence Resources advises it intends to drill an exploration well in the Southern Porcupine Basin.

Operations were scheduled to begin today (Monday 3 July) to drill the well at a depth of 2,250 metres some 220km off the South West Coast of Ireland.

Drilling is expected to take 60 days to complete, subject to weather and operational delays.

The dynamically positioned drill ship Stena IceMax (Callsign 2FMJ5) will carry out the drilling, supported by platform supply vessels Sjoborg (Callsign OZ-2075), Edda Frende (Callsign LCOB) and Skandi Flora (Callsign LEVX). The emergency rapid response vessel is Esvagt Don (Callsign MZWQ6).

There will be a safety exclusion zone of 500m radius from the drill ship. Regular safety messages will be broadcast on VHF Channel 16 by Esvagt Don throughout the project. Radio navigation warnings will also be issued several times daily by the Irish Coast Guard

All vessels, particularly those engaged in fishing, are requested to give the Stena IceMax and accompanying vessels a wide berth and keep a sharp lookout in the relevant areas.

Full details of the drilling area are included in Marine Notice No 28 of 2017, a PDF of which is available to read or download HERE.

#Oil&Gas - Providence Resources is divesting almost a third of its interest in its Spanish Point prospect, as The Irish Times reports.

The Irish oil and gas exploration company intends to sell off a 32% "non-operated interest" in the area off the coast of Co Clare, in the northern part of the Porcupine Basin, which has been shown to hold enormous reserves of oil.

Providence delayed its own exploration at Spanish Point earlier this year due to "unforeseen changes" to its joint venture at the well.

But drilling is now expected to take place in 2017 pending State approval.

#Oil - The Blackford Dolphin semisubmersible drilling rig is expected to go to work off the south-west coast of Ireland next spring.

Offshore reports that Dolphin Drilling has negotiated the contract to appraise the Spanish Point prospect in the Porcupine Basin on behalf of Capricorn Ireland, subject to regulatory approval.

It will also drill early next year in British waters for MPX North Sea, with both contracts expected to last five months for a total revenue of €67 million.

The Porcupine Basin off Kerry has been identified as a source of enormous reserves of oil - after Petrel Resources announced the discovery of as much as one billion barrels of oil at the prospect late last year.

#MarineNotice - The latest Marine Notice from the Department of Transport, Tourism and Sport (DTTAS) advises that a drill ship will begin intervention work for Shell E&P Ireland Ltd on the Corrib Gas Field from late June to early July.

The vessel West Navigator (Call sign 3ERR2) is expected to be on location for a period of 45 days, weather permitting, to work on a series of wells. Co-ordinates are detailed in Marine Notice No 24 of 2013, a PDF of which is available to read or download HERE.

All mariners are reminded of the 'safety zone' in place around the Corrib Gas Field development, and especially those engaged in fishing are requested to give the West Navigator a wide berth of at least 500 metres.

The vessel will be listening on VHF Channel 16 throughout the project.

This follows notice of umbilical installation works between the Corrib Gas Field at the mainland that will continue till July, as previously reported on Afloat.ie.

#COASTAL NOTES - Providence Resources has found light out with its first appraisal well off the south coast of Ireland, Offshore reports.

The company's semi-submersible GSF Arctic III drilled a well in 100m water to a depth of more than 2km on its Barryroe structure in the north Celtic Sea.

Indications of hydrocarbons were noted during the drilling, and further tests have confirmed the presence of 12.5m of 'net pay' (the thickness of rock that can deliver oil at a profitable rate) with as much as 87% hydrocarbon saturation.

The next stage will be a well flow test programme to determine whether future oil extraction can proceed.

“The confirmation of high quality light oil within a porous and potentially laterally extensive sandstone system is extremely encouraging," said technical director John O'Sullivan.

As previously reported on Afloat.ie, plans by Providence Rescources to prospect for oil pn the east coast off Dalkey Island have been met with fierce opposition by mainland residents and environmental groups.

#DALKEY ISLAND PROSPECT - The Irish Whale and Dolphin Group (IWDG) has joined the chorus of opposition to the proposed oil and gas exploration off Dalkey Island in Co Dublin.

As previously reported on Afloat.ie, Providence Resources has applied for a foreshore licence to search for oil or gas about 6km out to sea on the Kish Bank Basin.

But the prospect has provoked a split in the local community over the potential risks and benefits, with many calling for a public enquiry into the licence before it is granted.

This evening an urgent meeting in Dun Laoghaire will address the public's concerns, which have been echoed by the IWDG.

"The Kish Bank and adjacent waters are important for cetaceans," said the group in a statement. "In addition, sightings of bottlenose dolphins have increased dramatically in the area following the presence of a group of three individuals since August 2010."

The IWDG is concerned about the potential effects on dolphins and porpoises that "could due to noise generated from the drilling process", noting that "there is little published data on the intensity and effects of sound generated by drilling".

Protest group Protect Our Coast has launched a online petition against the Dalkey Island Prospect citing concerns over the proximity of the drilling area to the mainland as well as the Special Protection Area of Dalkey Island, which is a haven for marine wildlife.

#POWER FROM THE SEA - Irish oil and gas firm Providence Resources has been awarded a licence to explore near Dalkey Island, the Irish Independent reports.

The standard licence issued by the Department of Communications, Energy and Natural Resources lasts for up to six years, split into two three-year phases.

Providence hopes to drill at least one well during the initial phase in the Kish Bank Basin, where previous exploration drilling confirmed the presence of oil suitable for petroleum production.

The group is also applying for a foreshore licence for the purpose of well site surveys and drilling operations.

As previously reported on Afloat.ie, Providence Resources is one of the 12 companies that were awarded 13 Licensing Options between them in the 2011 Atlantic Margin Licensing Round.

Sharks in Irish waters

Irish waters are home to 71 species of shark, skates and rays, 58 of which have been studied in detail and listed on the Ireland Red List of Cartilaginous fish. Irish sharks range from small Sleeper sharks, Dogfish and Catsharks, to larger species like Frilled, Mackerel and Cow sharks, all the way to the second largest shark in the world, the Basking shark. 

Irish waters provide a refuge for an array of shark species. Tralee Bay, Co. Kerry provides a habitat for several rare and endangered sharks and their relatives, including the migratory tope shark, angel shark and undulate ray. This area is also the last European refuge for the extremely rare white skate. Through a European Maritime and Fisheries Fund (EMFF) project, Marine Institute scientists have been working with fishermen to assess the distribution, diversity, and monthly relative abundance of skates and rays in Tralee, Brandon and Dingle Bays.

“These areas off the southwest coast of Ireland are important internationally as they hold some of the last remaining refuges for angel shark and white skate,” said Dr Maurice Clarke of the Marine Institute. “This EMFF project has provided data confirming the critically endangered status of some species and provides up-to-date information for the development of fishery measures to eliminate by-catch.” 

Irish waters are also home to the Black Mouthed Catshark, Galeus melastomus, one of Ireland’s smallest shark species which can be found in the deep sea along the continental shelf. In 2018, Irish scientists discovered a very rare shark-nursery 200 nautical miles off the west coast by the Marine Institute’s ROV Holland 1 on a shelf sloping to 750 metres deep. 

There are two ways that sharks are born, either as live young or from egg casings. In the ‘case’ of Black Mouthed Catsharks, the nursery discovered in 2018, was notable by the abundance of egg casings or ‘mermaid’s purses’. Many sharks, rays and skate lay eggs, the cases of which often wash ashore. If you find an egg casing along the seashore, take a photo for Purse Search Ireland, a citizen science project focusing on monitoring the shark, ray and skate species around Ireland.

Another species also found by Irish scientists using the ROV Holland 1 in 2018 was a very rare type of dogfish, the Sail Fin Rough Shark, Oxynotus paradoxus. These sharks are named after their long fins which resemble the trailing sails of a boat, and live in the deep sea in waters up to 750m deep. Like all sharks, skates and rays, they have no bones. Their skeleton is composed of cartilage, much like what our noses and ears are made from! This material is much more flexible and lighter than bone which is perfect for these animals living without the weight of gravity.

Throughout history sharks have been portrayed as the monsters of the sea, a concept that science is continuously debunking. Basking sharks were named in 1765 as Cetorhinus maximus, roughly translated to the ‘big-nosed sea monster’. Basking sharks are filter feeders, often swimming with their mouths agape, they filter plankton from the water.

They are very slow moving and like to bask in the sun in shallow water and are often seen in Irish waters around Spring and early Summer. To help understand the migration of these animals to be better able to understand and conserve these species, the Irish Basking Shark Group have tagged and mapped their travels.

Remarkably, many sharks like the Angel Shark, Squatina squatina have the ability to sense electricity. They do this via small pores in their skin called the ‘Ampullae of Lorenzini’ which are able to detect the tiny electrical impulses of a fish breathing, moving or even its heartbeat from distances of over a kilometre! Angel sharks, often referred to as Monkfish have a distinctively angelic shape, with flattened, large fins appearing like the wings of an angel. They live on the seafloor in the coastal waters of Ireland and much like a cat are nocturnal, primarily active at night.

The intricate complexity of shark adaptations is particularly noticeable in the texture of their skin. Composed of miniscule, perfectly shaped overlapping scales, the skin of shark provides them with protection. Often shark scales have been compared to teeth due to their hard enamel structure. They are strong, but also due to their intricate shape, these scales reduce drag and allow water to glide past them so that the shark can swim more effortlessly and silently. This natural flawless design has been used as inspiration for new neoprene fabric designs to help swimmers glide through the water. Although all sharks have this feature, the Leafscale Gulper Shark, Centrophorus squamosus, found in Ireland are specifically named due to the ornate leaf-shape of their scales.
