The General Lighthouse Authorities (GLAs) of the United Kingdom and Ireland – Trinity House, Northern Lighthouse Board and Irish Lights have announced the requirement for an aviation service to support their vital safety service for mariners.

Known as the Tri-GLA Aviation Services Project (ASP), the contract to provide a dedicated aviation service is for a ten-year period from 1 December 2027, with the option to extend for up to a further two years.

An effective aviation service is a vital element of the GLAs’ service to the mariner. For many aids to navigation, due to their location and the nature of the work to be carried out, air travel is the only means of access. Not having an aviation service, even for a short period of time, has the potential to make a serious impact upon the critical statutory services delivered by the GLAs around the UK and Ireland.

Most flights involve carrying both passengers (GLA staff, subcontractors and approved third parties) and cargo to coastal and offshore lighthouses. This may require take off and landing from vessels at sea. Tasks will also include underslung loads that represent between 15% and 32% of the operational flying tasks per year, noting that such tasks will be separate from passenger transfers. Experience is therefore essential in Helicopter External Sling Load Operations (HESLO).

The GLAs are not seeking tenders at this time but will be carrying out Market Engagement to seek supplier views to help inform the procurement process. Any response to this Market Engagement by a supplier does not constitute a formal tender to the ASP procurement process, which the GLAs intend to commence in the Autumn of 2024.

Tri-GLA ASP Market Engagement Questionnaire*
Interested parties have the opportunity to complete a Market Engagement Questionnaire – see link below. The deadline for responding is by 21 March 2024.

Tri-GLA ASP Market Engagement Event – 5 April 2024 from 1000 to 1200 GMT
The GLAs invite interested parties to a virtual market engagement event where they will present an overview of the ASP Procurement and take questions. Details to follow.

The General Lighthouse Authority which is responsible for England, Wales, Channel Islands and Gibraltar, Trinity House is joining aids to navigation authorities around the world to mark the first ever World Marine Aids to Navigation Day held today, July 1st.

In addition to Trinity House, Afloat adds the other GLA counterparts are the Commissioners of Irish Lights and the Northern Lighthouse Board responsible for Scottish waters and the Isle of Man. Today's inaugural event is established to celebrate and promote the role of marine aids to navigation (AtoNs) and highlight the importance of safety at sea.

The body behind the day is IALA (the International Association of Marine Aids to Navigation and Lighthouse Authorities), a non-profit international technical association established in 1957 to gather together marine aids to navigation authorities, manufacturers, consultants and scientific and training institutes from all parts of the world.

IALA’s 305 members—whether national or industrial—assemble across a number of committees and working groups to exchange and compare their experiences and achievements, with a view to drafting and publishing IALA Standards, Recommendations and Guidelines.

The aim of IALA—to which Trinity House subscribes and contributes—is to foster the safe, economic and efficient movement of vessels, through improvement and harmonisation of aids to navigation worldwide and other appropriate means, for the benefit of the maritime community and the protection of the environment. Trinity House was a founding member of IALA in 1957.

The idea of launching the World Marine Aids to Navigation Day annually on 1 July was agreed at IALA’s 2018 conference in the Republic of Korea.

As a focal point for highlighting the importance of aids to navigation as a service for all mariners, Trinity House has chosen to emphasise its statutory duty as an auditor and inspector of local aids to navigation, rather than its more well-known duty as a provider of general aids to navigation such as lighthouses, lightvessels and buoys.

Local aids to navigation are owned and operated by Local Lighthouse Authorities rather than Trinity House, but the powers and duties granted to Trinity House by the Merchant Shipping Act 1995 require it to audit and inspect over 11,000 local AtoNs. The work is carried out by Trinity House’s Inspector of Seamarks and the Local AtoN Manager, both of whom enjoy meeting local operators and seeing so many often-hidden corners of the nation.

Inspector of Seamarks Captain Graeme Proctor says of the cyclical inspection schedule: “It’s a lot like painting the Forth Bridge, but I really enjoy meeting local Harbour Masters and their teams. It is hard work and a lot of long days, but there will often be a cup of tea waiting for me in the harbour office in the winter and we do enjoy an ice cream by the seaside in the summer months. Although it may not be the most famous of Trinity House’s contributions to maritime Britain, it’s a vital role for safety and is great for keeping us in touch with local aids to navigation providers and the marine users themselves.”

Maritime Minister Nusrat Ghani said: “Lighthouses have a place in all of our hearts but their longstanding role can never be underestimated. Aids to navigation are crucial to keeping people safe at sea, alerting them to potential dangers. Our lighthouse authorities, including Trinity House, do a fantastic job of keeping our lighthouses, buoys and other assistance vessels in good condition around the clock.”

Trinity House and IALA encourage everyone with an appreciation of the various types of marine aid to navigation to take to social media to share their favourite AtoNs with #WAtoNDay.

#Lighthouses - The Research and Radionavigation team (R&RNAV) that supports the three General Lighthouse Authorities (GLAs) of the UK and Ireland - Irish Lights, the Northern Lighthouse Board and Trinity House will now be known as GLA Research and Development (GRAD).

GRAD will continue with its work to undertake research and development of physical and radio marine aids to navigation, support systems and their integration to support the GLAs’ mission to deliver a reliable, efficient and cost-effective aids to navigation service for the benefit and safety of all mariners.

In recent years, the team’s successes have included a number of world firsts in the fields of Radionavigation and visual signalling; GRAD and its staff are recognised the world over for their knowledge and achievements in the provision and future provision of marine aids to navigation.

The big impact made by this small team not only reflects well on GRAD but on all the GLAs and the UK and Ireland. GRAD will continue to support the GLAs’ objectives, strategies and plans while supporting operational requirements over the coming years.

More information about the work of GRAD can be found at www.gla-rad.org

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.
