A rather obscure-looking vessel  that once served as a oil-tanker during World War II and  which managed to stave off successfully an enemy U-Boat attack, arrived into the Port of Cork yesterday, writes Jehan Ashmore.
The vessel, the Henry P Lading, which now works as a cable/pipe-laying barge, was towed into the harbour by the tug Thor and was joined by the Cobh-based tug, Breedbank (see photo). The barge is to lay installation cables between Whitegate Oil Refinery and Ringaskiddy in a project that is expected to take approximately three weeks to complete as four cables will be laid in four separate runs across the channel.

To read further information about the cable installation project which is listed on the Port of Cork Company website under Notice to Mariners (No. 6 of 2011) click here.

The odd appearance of the barge masks a colourful and chequered career, as only a remnant of the original vessel survives (see photo). Only the forward section and bow (90m long X 20m beam) remain after the partial scrapping of the former oil tanker, Esso København, which took place nearly fifty years ago.

She was launched in 1930 as the MS Peter Hurll by the Palmers Shipbuilding and Iron Company Ltd (Yard/Hull no. 479) at Hebburn-on-Tyne, England. Measuring 11,952grt the tanker was commissioned for Baltisch-Amerik Petroleum Import G.m.b.H. (Waried Tankschiff Rhed.) of Danzig. For further details click here.

The vessel's profile was typical of the era, with a 'two-island' arrangement where the bridge superstructure is sited amidships and separated from the crew's accommodation quarters located aft on the poop deck at the stern.

At 452-foot long, the 17,585dwt vessel had a cargo carrying capacity of 138,108 barrels, which had an assigned pumping rate of 4,000 barrels an hour. The twin-screw diesel powered vessel had 5,300 brake horsepower engines that gave a speed of 12.3 knots.

In 1935 the vessel was sold to the Panama Transport Co. of Panama. While en route to Aruba, with an American crew, war was declared in Europe on  September 3, 1939. At the Caribbean island's port of Las Piedras the Peter Hurll loaded her first war-time cargo of 106,514 barrels of fuel and crude oils bound for Everett, Mass.

Throughout the war years the Peter Hurll was crewed at various times between  Americans and Danes. To read in greater detail the career history of the vessel and an account of the attempted U-Boat attack on the Peter Hurll click here. The tanker had several sisters, the F. H. Bedford Jr, J. H. Senior,  J.A. Mowinckel and The Heinrich v. Riedemann which was lost on April 16, 1942.

Only a few months after the war in February 1946, the Peter Hurll bunkered the Queen Mary, which was moored alongside Pier 90 on the North River, New York. In less than 10 hours the vessel tranferred 27,797 barrels of fuel in a direct tanker-to-ship delivery of fuel oil. The famous 80,000 tonnes Cunard liner which like the tanker, was also built in 1930, had been recently re-converted from a troopship to her peacetime role as a passenger-liner.

In 1967 the liner retired and the vessel is moored at Long Beach, California, as a static hotel, restaurant and museum (see www.queenmary.com).

Two years later the Peter Hurll changed ownership to Det Danske Petroleums A/S of Copenhagen but later under the control of Dansk Esso A/S was  renamed Esso København (see link) and the vessel was enlarged to a tonnage of 12,043grt.

In 1952, the vessel was taken to Odense, Denmark by H. J. Hansen, where the vessel was partially broken-up. The remaining fore-end survived and was rebuilt as a cable / pipe laying barge in 1963 (click here). The structure which essentially is a barge was named Henry P Lading for new owners, Nordisk Kabel og Traadfabrikker A/S, Copenhagen.

At one stage the barge was renamed "Nkt Cables a/S" but in 2002 the barge was sold to Jydsk Dykkerfirma ApS, now named JD Contractor A/S. The company (click here) is the largest underwater contractor in Denmark, providing diving assignments and the laying and embedding of submarine cables and pipelines worldwide.

Only late last year, scuba-divers found a fully intact World War I U-Boat on the seabed just outside Cork harbour. To read more about the U-Boat which sank some 93 years ago and photos click here.

Ireland's Offshore Renewable Energy

Because of Ireland's location at the Atlantic edge of the EU, it has more offshore energy potential than most other countries in Europe. The conditions are suitable for the development of the full range of current offshore renewable energy technologies.

Offshore Renewable Energy FAQs

Offshore renewable energy draws on the natural energy provided by wind, wave and tide to convert it into electricity for industry and domestic consumption.

Offshore wind is the most advanced technology, using fixed wind turbines in coastal areas, while floating wind is a developing technology more suited to deeper water. In 2018, offshore wind provided a tiny fraction of global electricity supply, but it is set to expand strongly in the coming decades into a USD 1 trillion business, according to the International Energy Agency (IEA). It says that turbines are growing in size and in power capacity, which in turn is "delivering major performance and cost improvements for offshore wind farms".

The global offshore wind market grew nearly 30% per year between 2010 and 2018, according to the IEA, due to rapid technology improvements, It calculated that about 150 new offshore wind projects are in active development around the world. Europe in particular has fostered the technology's development, led by Britain, Germany and Denmark, but China added more capacity than any other country in 2018.

A report for the Irish Wind Energy Assocation (IWEA) by the Carbon Trust – a British government-backed limited company established to accelerate Britain's move to a low carbon economy - says there are currently 14 fixed-bottom wind energy projects, four floating wind projects and one project that has yet to choose a technology at some stage of development in Irish waters. Some of these projects are aiming to build before 2030 to contribute to the 5GW target set by the Irish government, and others are expected to build after 2030. These projects have to secure planning permission, obtain a grid connection and also be successful in a competitive auction in the Renewable Electricity Support Scheme (RESS).

The electricity generated by each turbine is collected by an offshore electricity substation located within the wind farm. Seabed cables connect the offshore substation to an onshore substation on the coast. These cables transport the electricity to land from where it will be used to power homes, farms and businesses around Ireland. The offshore developer works with EirGrid, which operates the national grid, to identify how best to do this and where exactly on the grid the project should connect.

The new Marine Planning and Development Management Bill will create a new streamlined system for planning permission for activity or infrastructure in Irish waters or on the seabed, including offshore wind farms. It is due to be published before the end of 2020 and enacted in 2021.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE. Is there scope for community involvement in offshore wind? The IWEA says that from the early stages of a project, the wind farm developer "should be engaging with the local community to inform them about the project, answer their questions and listen to their concerns". It says this provides the community with "the opportunity to work with the developer to help shape the final layout and design of the project". Listening to fishing industry concerns, and how fishermen may be affected by survey works, construction and eventual operation of a project is "of particular concern to developers", the IWEA says. It says there will also be a community benefit fund put in place for each project. It says the final details of this will be addressed in the design of the RESS (see below) for offshore wind but it has the potential to be "tens of millions of euro over the 15 years of the RESS contract". The Government is also considering the possibility that communities will be enabled to invest in offshore wind farms though there is "no clarity yet on how this would work", the IWEA says.

Based on current plans, it would amount to around 12 GW of offshore wind energy. However, the IWEA points out that is unlikely that all of the projects planned will be completed. The industry says there is even more significant potential for floating offshore wind off Ireland's west coast and the Programme for Government contains a commitment to develop a long-term plan for at least 30 GW of floating offshore wind in our deeper waters.

There are many different models of turbines. The larger a turbine, the more efficient it is in producing electricity at a good price. In choosing a turbine model the developer will be conscious of this ,but also has to be aware the impact of the turbine on the environment, marine life, biodiversity and visual impact. As a broad rule an offshore wind turbine will have a tip-height of between 165m and 215m tall. However, turbine technology is evolving at a rapid rate with larger more efficient turbines anticipated on the market in the coming years.

 

The Renewable Electricity Support Scheme is designed to support the development of renewable energy projects in Ireland. Under the scheme wind farms and solar farms compete against each other in an auction with the projects which offer power at the lowest price awarded contracts. These contracts provide them with a guaranteed price for their power for 15 years. If they obtain a better price for their electricity on the wholesale market they must return the difference to the consumer.

Yes. The first auction for offshore renewable energy projects is expected to take place in late 2021.

Cost is one difference, and technology is another. Floating wind farm technology is relatively new, but allows use of deeper water. Ireland's 50-metre contour line is the limit for traditional bottom-fixed wind farms, and it is also very close to population centres, which makes visibility of large turbines an issue - hence the attraction of floating structures Do offshore wind farms pose a navigational hazard to shipping? Inshore fishermen do have valid concerns. One of the first steps in identifying a site as a potential location for an offshore wind farm is to identify and assess the level of existing marine activity in the area and this particularly includes shipping. The National Marine Planning Framework aims to create, for the first time, a plan to balance the various kinds of offshore activity with the protection of the Irish marine environment. This is expected to be published before the end of 2020, and will set out clearly where is suitable for offshore renewable energy development and where it is not - due, for example, to shipping movements and safe navigation.

YEnvironmental organisations are concerned about the impact of turbines on bird populations, particularly migrating birds. A Danish scientific study published in 2019 found evidence that larger birds were tending to avoid turbine blades, but said it didn't have sufficient evidence for smaller birds – and cautioned that the cumulative effect of farms could still have an impact on bird movements. A full environmental impact assessment has to be carried out before a developer can apply for planning permission to develop an offshore wind farm. This would include desk-based studies as well as extensive surveys of the population and movements of birds and marine mammals, as well as fish and seabed habitats. If a potential environmental impact is identified the developer must, as part of the planning application, show how the project will be designed in such a way as to avoid the impact or to mitigate against it.

A typical 500 MW offshore wind farm would require an operations and maintenance base which would be on the nearby coast. Such a project would generally create between 80-100 fulltime jobs, according to the IWEA. There would also be a substantial increase to in-direct employment and associated socio-economic benefit to the surrounding area where the operation and maintenance hub is located.

The recent Carbon Trust report for the IWEA, entitled Harnessing our potential, identified significant skills shortages for offshore wind in Ireland across the areas of engineering financial services and logistics. The IWEA says that as Ireland is a relatively new entrant to the offshore wind market, there are "opportunities to develop and implement strategies to address the skills shortages for delivering offshore wind and for Ireland to be a net exporter of human capital and skills to the highly competitive global offshore wind supply chain". Offshore wind requires a diverse workforce with jobs in both transferable (for example from the oil and gas sector) and specialist disciplines across apprenticeships and higher education. IWEA have a training network called the Green Tech Skillnet that facilitates training and networking opportunities in the renewable energy sector.

It is expected that developing the 3.5 GW of offshore wind energy identified in the Government's Climate Action Plan would create around 2,500 jobs in construction and development and around 700 permanent operations and maintenance jobs. The Programme for Government published in 2020 has an enhanced target of 5 GW of offshore wind which would create even more employment. The industry says that in the initial stages, the development of offshore wind energy would create employment in conducting environmental surveys, community engagement and development applications for planning. As a site moves to construction, people with backgrounds in various types of engineering, marine construction and marine transport would be recruited. Once the site is up and running , a project requires a team of turbine technicians, engineers and administrators to ensure the wind farm is fully and properly maintained, as well as crew for the crew transfer vessels transporting workers from shore to the turbines.

The IEA says that today's offshore wind market "doesn't even come close to tapping the full potential – with high-quality resources available in most major markets". It estimates that offshore wind has the potential to generate more than 420 000 Terawatt hours per year (TWh/yr) worldwide – as in more than 18 times the current global electricity demand. One Terawatt is 114 megawatts, and to put it in context, Scotland it has a population a little over 5 million and requires 25 TWh/yr of electrical energy.

Not as advanced as wind, with anchoring a big challenge – given that the most effective wave energy has to be in the most energetic locations, such as the Irish west coast. Britain, Ireland and Portugal are regarded as most advanced in developing wave energy technology. The prize is significant, the industry says, as there are forecasts that varying between 4000TWh/yr to 29500TWh/yr. Europe consumes around 3000TWh/year.

The industry has two main umbrella organisations – the Irish Wind Energy Association, which represents both onshore and offshore wind, and the Marine Renewables Industry Association, which focuses on all types of renewable in the marine environment.
