As summer is underway along with leisure activities, ABP’s Port of Southampton has published its Marine Leisure Guide to help recreational users stay safe in and around The Solent and Southampton Water.

As one of the UK’s busiest ports located in Hampshire, Portsmouth is visited by cruise ships, container ships, automotive carriers, tankers and ferries, as well as countless leisure vessels and craft as people enjoy time on one of the country’s most popular stretches of water. It is for this reason that ABP issues this downloadable guidance to help those using the water know how to prepare well.

“The Solent and Southampton Water are fantastic places to be, and we want people to stay safe when they venture out,” says ABP Southampton Harbour Master, Steve Masters. “The guide can be easily downloaded to a mobile device, and we strongly advise people take time to familiarise themselves with it to make sure they get the basics right.”

The Marine Leisure Guide contains helpful information on everything from pre-departure preparation such and what equipment to carry, understanding tides and weather, lights and signals used by vessels, and navigational safety. It also contains information on Local Notices to Mariners and being aware of the various VHF channels used by HM Coastguard, Southampton Pilots and ABP’s Southampton’s Vessel Traffic Service, which controls shipping movements in and around The Solent and Southampton Water.

A handy chartlet provides a map of the area, with information on channel approaches, different speed restrictions and much more.

The Marine Leisure Guide is available to download from the Southampton VTS website which links to download full copy of the guide (also available in a printed version).

Dublin Port Company

Dublin Port, the largest port in Ireland, is situated in the heart of Ireland's vibrant capital city. Dublin Port Company's mission is to facilitate the flow of goods, passengers and information through the port.

Dublin Port, as an organisation, has a long and remarkable history, dating back 300 years from 1707 to 2007. There have been many famous moments and famous visitors in that time Captain William Bligh's (of 'Mutiny on the Bounty' fame) involvement in the Port in 1800 has left a lasting legacy.

Bligh conducted a study of the tidal flows in Dublin Bay, which led to the construction of the Great South Wall. This construction has resulted in the formation of the present Bull Island, which did not exist in 1800.

Another famous person, involved in the development of the Port was the famous Port engineer Bindon Blood Stoney. He designed the diving bell now located on Sir John Rogerson's Quay, which was used in the construction of the North Wall Extension. (Pictured: sugar storage at Custom House Docks).

Dublin Bay Guidance Notes for Leisure Craft

For all recreational craft using Dublin Port and Bay, compiled by Dublin Port Company in consultation with local yacht and boat clubs

Facts to bear in mind:

1. As both the number of large commercial ships and recreational craft using Dublin Port is increasing it is essential that close quarter situations do not arise.

2. Commercial vessels using Dublin Port or Dun Laoghaire Port normally have a qualified pilot or certified master with proven local knowledge on board. They 'listen out' on VHF channel 12 when in Dublin Port’s jurisdiction.

3. Commercial vessels will follow the routes designated in the attached illustration. All recreational craft when obliged to navigate within such areas should do so with extreme caution following the Int. Collisions Regulations.

4. Large conventional commercial craft travel at a manoeuvering speeds of between 8 to 15 knots whilst within the ports jurisdiction. The lower limit varies from ship to ship and is 'as safe navigation permits'.

5. Ships will be traveling faster than you may estimate, even in congested waters.

6. Ships that are light or partially loaded, particularly in windy conditions, will require a higher minimum speed to remain under full control.

7. A large ship visible on the horizon may take no more than 10 minutes to reach you under clear conditions, under hazy conditions this time could be much less. At 10 knots a ship will travel a nautical mile in 6 minutes, at 15 knots it takes only 4 minutes to travel one nautical mile.

8. A large deep draught ship cannot easily avoid small craft in a narrow channel. It is up to leisure craft to keep clear (see Rule 9 Int. Collision Regs excerpt at end of this page).

9. A ship slowing down does not steer very well. It requires the action of its propeller to respond. When the propellor is going 'astern' the ship’s steering will be adversely affected.

10. As well as large cargo ships, a variety of working craft also use the port, tugs, pilot cutters, dredgers, fast ferries, barges under tow etc. In particular a towing line may be partly submerged and therefore potentially dangerous to other craft passing too close.

 

What should you do?

1. Avoid sailing in the buoyed channel area, avoid sailing within 0.5 nautical mile of the Dublin Bay buoy and in the separation schemes, (see illustration). This is especially critical in periods of reduced visibility. When obliged to cross the fairway, cross at right angles to the traffic flow. Also obey rule 9 of the Collision Regulations by either keeping to the starboard side of the channel or if the water depth allows outside the buoyed channel.

2. Keep a good lookout. Be aware of all ship movements, especially astern of you.

3. Do not underestimate the speed of ships. Allow plenty of time to take effective evasive action in the vicinity of large ships.

4. Be visible. At night make sure your navigation lights can be clearly seen. If you see the navigation lights of a vessel approaching and you think that he has not seen you, get out of the way. Also use a torch or search-light to illuminate the sails (if appropriate). Remember (as indicated in the attached illustration), from the bridge of a loaded container ship or large tanker the captain/pilot may lose sight of you a half a nautical mile ahead, although you can see that ship clearly from your vessel at all times.

5. Keep watch at night. You may have difficulty seeing a large ship approach, even on a clear night. In reduced visibility you may have little warning of its approach. If you see a black shadow against shore lights or as a growing shadow, at that point a close quarter situation is already imminent. Remember you cannot be easily seen at night (particularly in a background of lights) and judging distances at night can prove difficult.

6. Watch the ships navigation lights. If you see both ships sidelights you are dead ahead, follow the Int. Collision Regs. and any alteration of course should be early, substantial and be visible to the approaching ship. Be aware that ships alter course at the Dublin Bay buoy and No.3/No.4 buoys. Be aware of your position and the position of other vessels around you at all times.

7. Know the whistle signals (see illustration). Five or more short and rapid blasts on the ships whistle indicates the ship is in doubt about your action or the lack thereof. Check immediately if this signal was meant for you, if so take immediate and appropriate action. Three short blasts means 'my engines are going astern' one short blast means 'I am altering my course to starboard'. Two short blasts "I am altering my course to port".

8. Keep your VHF tuned to channel 12 the port working frequency, and have the volume high enough to hear above the noise of the engine. Listen for traffic information from Dublin Port V.T.S. Only if you are the controlling vessel in a flotilla of other vessels, and you observe a hazardous situation developing, or in the event of an emergency developing within the ports jurisdiction, you should transmit on VHF channel 12.

Remember CH 12 is Dublin Port’s primary working channel and used to manage port traffic. No private or unneccessary communications to take place on this channel.

Area 1 - from Dublin Bay Buoy to Poolbeg Lighthouse
Small craft shall not navigate inside the fairway and should remain outside the line of buoys. If it is necessary to cross the fairway, crossing should be at right angles.

Area 2 - Poolbeg Lighthouse to No. 14 Buoy
Small craft shall comply with the International Regulations for Prevention of  Collisions at Sea and shall keep as near to the outer limit of the channel which lies on her starboard side as is safe and practicable. Rule 9 does not apply outside the channel and craft may pass outside the buoys when and where it is safe to do so.  If it is necessary to cross the channel, e.g. to enter area 3, crossing should be at right angles, at a position abeam of the ESB Jetty (Berth 48).

Area 3 - No. 14 Buoy to the west
All small craft should pass along the south side of the channel, remaining as far as is practicable to that side.

General
All craft shall operate under power when within areas 2 and 3, but may additionally raise their sails outside the channel but not in the channel.

1. No sailing in the channel, craft should only cross at right angles when it is safe to do so.

2. Maintain a listening watch on channel VHF 12 and avoid unnecessary communication.

 

Keep a sharp lookout and keep clear of all shipping.

Attention of all skippers is drawn to the annual Notice to Mariners No. 7 concerning small craft.

Capt. David T. Dignam, Harbour Master. 31st March 2006

 

 

Collision Avoiding Check List

Avoid the busy shipping channels and routes. Cross them at right angles and as quickly as possible after checking that it is safe to do so. Recreational users of the port area are particularly requested to be familiar with the Int. Collision Regulations (particularly Rule 9), Dublin Port Bye Laws, Small Craft (Leisure) Regulations (see chartlet) and Local Notices to Mariners (particularly No.7). Information is also available on the Dublin Port web site, www. dublinport.ie

Remember:

• Keep a good lookout, particularly at night

• Do not under-estimate the speed of ships

• Be visible

• Watch the lights of other vessels

• Know the whistle signals

• Keep your VHF tuned to channel 12

• Obey any instructions given by Dublin Port VTS. They are also interested in your safety.

 

International Regulations for the Prevention of Collisions at Sea

Rule 9 - Narrow Channels (Excerpt)

(a) A vessel proceeding along the course of a narrow channel or fairway shall keep as near to the outer limit of the channel or fairway, which lies on her starboard side as, is safe and practicable

(b) A vessel of less than 20 metres in length or a sailing vessel shall not impede the passage of a vessel which can safely navigate only within a narrow channel or fairway.

(c) A vessel engaged in fishing shall not impede the passage of any other vessel navigating within a narrow channel or fairway.

(d) A vessel shall not cross a narrow channel or fairway if such crossing impedes the passage of a vessel which can safely navigate only within such channel or fairway. The latter vessel may use the sound signal prescribed in Rule 34(d) or in doubt as to the intention of the crossing vessel.

 

Rule 10 – Traffic Separation Schemes (Excerpt)

(i) A vessel of less than 20 metres in length or a sailing vessel shall not impede the safe passage of a power-driven vessel following a traffic lane.

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.
