Lloyd’s Register’s reputation as class leader of the superyacht industry received yet more global acclaim at this month’s 2015 World Superyacht Awards when 10 out of the 18 award-winning vessels were classed with or built under LR class.

The blue ensign for motor yachts at this year’s event in Amsterdam went to Grace E, aptly complying with the Red Ensign Group’s Large Yacht Code and Lloyd’s Register’s rules for superyachts. With a cruising speed of 14 knots, a maximum speed of 16.5 knots and a range of 8,637 nautical miles from her 185,000-litre fuel tanks, the vessel has the yacht aficionado’s ideal blend of performance and luxury.

Top prize in the ultra-large motor yachts category went to the 95.2m-long Kismet, classed by LR and built by Lürssen, while Heesen Yachts’ LR-classed MySky won the award for 500gt-plus vessels. Another Heesen vessel, Elena, which is also LR-classed, clinched the prestigious Neptune

Comment

With reputedly the third largest natural harbour in the world and the deepest in Western Europe, it is not really surprising that the founders of Pendennis shipyards chose to start a business in the Cornish port of Falmouth.

The port has a long and memorable history. For more than 150 years the famous Falmouth Packet postal service operated out of it linking the UK with many parts of its growing colonial empire. Until recently because of its location as the UK’s most southernmost port, Royal Navy ships often used Falmouth as their first port-of-call when returning from global war zones.

So when Pendennis Shipyard started operating out of Falmouth in the 1980s, the company had the twin benefits of a ready-made deepwater harbour and a sizeable local skillbase. The company’s first project was a contract to build the 38-metre-long ketch Taramber. This was followed by a major refit of the 65m-long LR-classed schooner, Adix, in 1991, both projects winning the yard important yacht industry awards.

Fast forward two years to 1993 – the most eventful year in Pendennis’s early history. Now under new ownership, the company won a contract to restore the 55m-long classic racing schooner, Adela, which was originally built in 1903. The yacht, which was approved and classed by LR, won the yard another award. The year also marked the start of a major expansion programme.

Based in an expanding shipyard in one of the world’s largest natural harbours, the UK’s Pendennis Shipyard has been involved in many award-winning projects with classification by Lloyd’s Register

LR and Pendennis celebrate a 25-year collaboration

A new slipway was added to the Falmouth shipyard and a covered dry dock and 400-ton hoist installed.

Since then, LR has been involved in a number of significant Pendennis projects as well as regularly maintaining the two schooners Adix and Adela. In fact the Adix, which has just completed an eight-month refit overseen by LR, was the first yacht to berth in Pendennis’s capacious new 7,564m² wet basin added as part of a new two-year investment programme that began in 2013.

The basin, which was part-funded by the European Regional Development Fund (ERDF) and a local enterprise scheme, will enable superyachts to berth alongside and refits. It will also support yacht commissioning before and after time out of the water. As part of the expansion, the Falmouth-based company has built two 90m-long and one 45m-long double bay hall plus a suite of new workshops and offices. The yard now plans to raise the height of its drydock.

“These extensive improvements have been in response to the changes in the superyacht industry since the company was founded 27 years ago. Whilst in 1988 a yacht of over 50m was perceived to be large this is now the average LOA (length overall) of vessels visiting Pendennis. In 2014 the largest-volume yacht to date, Northern Star at 76.5m, commenced her seven-month refit. However this record has

already been superseded with the arrival of an 85.6m-long motor yacht. As the new wet basin and the pre-existing dry dock can cater for vessels up to 110m-long this record is sure to be surpassed in the future,” said Mike Carr, Managing Director of Pendennis Shipyard.

“Not only have the developments improved our facilities but they are projected to safeguard 360 existing jobs as well as expand our workforce. Our apprenticeship scheme is set to welcome a group of 12 young people this year, while a recruitment drive should see the workforce boosted by a further 40 staff in the winter of 2015.”

LR’s Senior Surveyor, Richard Cooper, who has been project manager for the certification and classification of many refits and rebuilds at the Falmouth site, said: “LR has been involved

with Pendennis Shipyard since 1990 and the refits we have overseen with the yard have meant extensive discussion and collaboration due to the detailed issues that arise.

“When the structure is inaccessible due to expensive joinery being impossible to remove, structural repairs may have to be undertaken to ensure the integrity of the vessel is maintained whilst avoiding dismantling joinery where possible. Accordingly we have developed procedures to ensure the structures can be repaired, and in many cases improved, without undue and extremely costly disturbance of bespoke joinery in many areas.”

Lloyd’s Register classes restoration of ‘beautiful butterfly’ Malahne

One of the largest and most significant projects Pendennis Shipyard and Lloyd’s Register (LR) have been involved with is the two-and-a-half year rebuild of the 1937-built motor yacht Malahne.

The classic yacht, which was originally classed by LR, was, to use the candid words of Richard Cooper, LR’s Project Manager for the Malahne rebuild, “at risk of an ignominious end when found languishing in a dilapidated condition following a series of poorly-executed alterations”.

During a long and chequered early history – including active service during the Second World War – the 50-metre-long Malahne had several changes of owner and the indignity of having her class suspended for two years. In 1960 she was bought by a company owned by the flamboyant Hollywood film producer Sam Spiegel. And, in what was referred to as a “never-ending Spiegel production”, she had frequent changes of captain and attracted famous film stars and royalty such as Prince Rainier of Monaco and Grace Kelly.

“Seeing the final transformation from her 1980s form back to her original design, her launch marks a proud moment for everyone involved.”

Mike Carr

Mike Carr, Managing Director of Pendennis Shipyard

During this eventful spell, the maintenance of the vessel was neglected and in 1978 her class had to be suspended once again. Five years later, Spiegel sold the yacht to a Saudi Arabian sheikh. The new owner made various modifications in an attempt to superimpose a more modern profile and superstructure on the vessel. Even her name was changed, to Adel XII.

After a further refit in 1999 the vessel was sold at least twice before she was bought through Edmiston Yacht Management by her current owner who had the passion and enthusiasm to restore her to her original design. “It was a challenge that many organisations would be reluctant to attempt,” said Cooper.

A project team to restore the vessel at Pendennis’s shipyard in Falmouth, UK, was led by Edmiston and the classic yacht experts G. L. Watson with naval architecture partner BMT Nigel Gee and approval and classification by Lloyd’s Register. In the words of the interior designer Guy Oliver: “Our brief was to make Malahne look as if she had been in continuous ownership since she was built.”

Cooper explained: “The major challenge was to survey the original structure and

specify the criteria for retaining it, to make sure such original techniques as riveting and lapped joints were applied and to use the vessel’s original equipment.

“We also needed to make sure the vessel was compliant with the latest regulations and to install additional equipment to satisfy the latest operational requirements such as air conditioning and sewage treatment and to address structural issues relating to the fabrication in steel, aluminium and wood.

“Finally, we needed to make sure the vessel met the latest requirements for the UK flag and to satisfy the Large Yacht Code (LY3) and other relevant conventions.”

So after keeping everything faithful to the original from lighting, anchors, the bridge telecom and the Malahne’s hand-painted surfaces to her period styling, the vessel was relaunched in March this year.

As one of the project team remarked as the yacht emerged from the Pendennis build shed: “It is like seeing a beautiful butterfly emerge into the sunlight!”

Mike Carr, Managing Director of Pendennis Shipyard, said: “Over the past two-and-a-half years the team here has worked

incredibly hard to bring Malahne back to life. Seeing the final transformation from her 1980s form back to her original design, her launch marks a proud moment for everyone involved. Our tradespeople from all areas have applied quality, care, pride and passion to every aspect of the project.

“There have been unprecedented opportunities to showcase their restoration skills, whilst sympathetically integrating modern systems. Malahne now commands a special place in the Pendennis fleet.”

How many of the world’s superyachts will be driven by some form of battery propulsion in 20 years’ time. Five per cent, 10% or even 20%? Only time will tell, but we do know that growing numbers of owners are turning to hybrid alternatives to help save fuel, reduce emissions and ensure smoother and quieter performances.

As a global technology leader and the main classification society for superyachts, Lloyd’s Register (LR) has been working with designers, owners and yacht-builders to find the most effective ways of using battery power in today’s yachts.

In fact LR has recently participated in the building of several diesel-electric yachts – notably a newly-delivered hybrid superyacht, the 83.5m-long Savannah, for Netherlands-based Feadship.

The yacht was built at Feadship’s yard in Aalsmeer near Amsterdam and approved and classed by LR. She is driven by a medium-speed Wärtsilä 9L20 four-stroke engine instead of the two higher-rev diesel engines used on conventional yachts. The engine drives three gensets made up of one million watts of Li-ion batteries, a single central propeller nacelle, and an in-line azimuthing thruster set in the vessel’s slipstream (see image above right).

The counter-rotating stern thruster just behind the main engine delivers extra

efficiency for the propeller, which is 40% larger than a normal propeller. This is the first time such a configuration has been applied to a yacht – although a similar system has been used on Japanese passenger ships.

Savannah’s novel propulsion system makes her 30% more fuel-efficient than comparable yachts of her size. The

batteries provide extra speed at the top end and allow proper loading of the generators at any speed.

For mid-range and shorter trips, she can be operated in electric mode, while for higher speeds – of 13 to 17 knots – she can use a combination of generators and diesel. To attain her top speed of 19 knots, all three systems can be used. The batteries also

enable the yacht to cruise extra quietly at slow speeds without the need to run the engines. Ted McCumber, the yacht owner’s Project Manager, told the Daily Telegraph: “It is not the individual technologies used on Savannah that are new in the yachting world, it is the way they have been combined.” Ben Boon, Manager New Projects at Feadship, told Yacht Focus: “This project was only possible thanks

to the vast experience and proactive co-operation between Lloyd’s Register, Feadship and its sub-contractors.”

For a yacht-owner the benefits of hybrid technology include a significant reduction in carbon footprint, very low emissions and compliance with the IMO’s emission control area (ECA) restrictions. Switching to battery power gives yachts greater

manoeuvrability in ports and coastal areas and smoother and quieter travel for passengers and guests.

As a result of our project work and research into hybrid technology, LR has produced a guide called Large battery installations. It takes a risk-based approach to battery use – from the start of a battery’s life when its cells are being manufactured to investigating how a battery installation affects or is affected by a vessel’s power system.

You can download a copy of the guide and watch a video about battery technology at: www.lr.org/technologyreport.

reality is that our costs are lower. This makes us very competitive. We also like to innovate and we have good in-house engineering expertise to help turn designs into reality,” said the General Manager.

In a wide-ranging discussion, we talk about new technology and some of the more exotic options becoming available as new power sources and more sophisticated power management systems are introduced to meet the efficiency and flexibility required by today’s owners and operators.

Turkish talent builds luxury superyachts in Istanbul

“Refits are an important source of work: While LR is in the yard, alongside is a 95m-long yacht which is nearing the end of a full refit programme.

Originally founded in Mecidiyeköy and with a facility on Istanbul’s Golden Horn, Turquoise Yachts, formerly known as Proteksan Turquoise, has been building yachts since 1973. In the early days the company built vessels up to 40 metres long. Today, as a well-established builder of luxury custom yachts in Turkey, the company can produce vessels of up to 85m in length.

The business has two facilities near Istanbul: a steel fabrication yard at Kocaeli and an outfitting facility with covered sheds in Pendik, Istanbul. The business was recently acquired by the Omani investor, Dr Mohammed Al Barwani, who also owns the Dutch custom yacht builder Oceanco, based at Alblasserdam, near Rotterdam.

Yacht Focus spoke to the yard’s General Manager, Necdet Salgür, about the

company’s activities and capabilities. He was keen to explain the benefits of ordering a luxury yacht in Turkey and why owners should build yachts in Turkey.

The key differentiator today, said Salgür, is the ability to deliver the highest levels of quality and innovation at a price level considerably below those available in many other yards in the European area. “We have highly skilled people in Turkey, we have access to an excellent supplier and contractor base, we have lots of experience – and the

Class is very important to us“We very much see LR as the leader when it comes to large yacht classification. Why? Because of the rules. LR has special rules for yachts and this provides the clarity we need,” said Turquoise Yachts General Manager, Necdet Salgür. He added that LR is always working to find a solution when the inevitable challenges emerge.

“We are always trying to bring to life the ideas and ambitions of our clients but we need to meet regulatory and safety requirements as well as operational needs. And when we have a complicated project we make sure we call LR in at the very beginning. Yacht-building is very challenging – and the main difficulty is the market. With the help of Lloyd’s Register and other service support we know we can handle the technical issues – but even LR can’t help us with the overall economic situation!” he said.

Profile of Turquoise Yachts

Turquoise Yachts’ main office is in Istanbul. It has an in-house team of designers and a workforce of craftsmen skilled in the use of materials such as wood, stainless steel and leather. To minimise noise and vibrations from both transmission and propellers, vessels are built with unique spring-type engine mounts and elastic shaft coupling and engine and gearbox arrangements specifically designed for close coupling.

Turquoise Yachts’ outfitting facility in the Pendik district of Istanbul was completed in 2007. This is an impressive 25,000m² landscaped location that can simultaneously accommodate four

yachts of up to 85m in length. It boasts a dock length of 110m and is used expressly for interior decoration and finishing work.

The company’s other shipyard was opened in 2005 and is located in Kocaeli across the bay from the Pendik facility. With its 120m-long dock, it has the capability and facilities to build yachts of up to 120m in length.

The Kocaeli site is where the steel and aluminum hull and superstructure work on yachts is completed, and also installation of machinery and heavy piping of up to 50,000m².

“We see a strong future for yacht building in Turkey.”

Necdet Salgür, General Manager, Turquoise Yachts

One upcoming challenge will be the NOx Tier III compliance for vessels built after 1 January 2016 and travelling in certain emission control areas (ECAs). Salgür pointed out: “Even mega-yachts do not have the space for scrubbers.” New technology will undoubtedly find a solution, however.

Definition of Large Yacht Code

The changing shapes of sailing yachts and the cutting-edge technology they incorporate mean the need for safety compliance and specialist knowledge in such key sectors as masts and rigging has never been greater

Raising the bar on masts and rigging

The evolution of yacht design and the use of new materials have prompted Lloyd’s Register to produce new guidelines on the building and compliance of vessels’ masts and rigging.

Called Guidance Notes for the Certification of Masts, Spars and Standing Rigging, the document helps designers, builders and owners develop virtually any rig configuration within the remit of the Large Yacht Code (LY3). The LR guidelines are unique because they are goal-based rather than prescriptive and have been devised to give owners and designers stage-by-stage, one-to-one matches with each of the legal requirements of the Code.

They also give all the parties involved in newbuild projects – from owners, designers and manufacturers to builders and authorities – a transparent view of their status in auditable trails and clear responsibilities at every stage of a vessel’s construction.

In the document, the certification process is modular and covers the following areas:

• concept design• structural design• manufacture and materials• stepping and verification of behaviour.

How LR can helpAs the leading classification society in the superyacht sector, LR has the knowledge and troubleshooting abilities to foresee problems and snags during the design and manufacture of a newbuild project.

Although we use the short name Large Yacht Code, it does not give the full picture of the code. The name in full means Large Commercial Yacht Code, with an emphasis on the ‘commercial’.

It means a yacht certified to this code is entitled to offer services on a commercial basis, making it subject to the requirements needed for other types of commercial vessel.

The flexibility of these new guidelines also enables us to be involved with the project from initial conception right through to the vessel’s completion, assisting the builder and owner through every stage of certification.

Our guidelines are explicitly based on first principles and therefore apply to all types of mast. While the examples we have included in the document are based on fore and aft type rigs (Bermuda), because they are the most common type used in the industry, the guidelines can also be applied to lateen sails and A-frame type masts. Put simply, any rig configuration can be examined and certified – subject to early involvement in the design by Lloyd’s Register.

Throughout the lifecycle of new or existing yachts we can help owners and managers improve and maintain the safety of their masts and rigging.

LR’s guidelines for the certification of masts and rigging are uniquely flexible

September 2015 / Mast safety

Owners, builders and designers planning to build yachts that comply with emission control areas (ECAs) have received some unexpected news.

Last year the IMO’s Marine Environment Protection Committee (MEPC) announced that the deadline for the modifications and changes needed for newbuild yachts to meet the IMO’s NOx Tier III emission standard had been delayed by five years from I January, 2016 to 1, January, 2021. The announcement seemed to imply that there was no need to comply with the standard until the later date.

This might be the case except that yachts with a keel-laying date on or after 1 January, 2016 that sail in NOx ECAs such as the seas and coasts around North America and the Caribbean which are very popular destinations for yachting will still require IMO Tier III-certified systems.

The IMO NOx Tier III standard applies to the following yachts:

• yachts over 24 metres • yachts over 500gt • engines over 130kW.

The new yachts will need to demonstrate that they are producing nearly 80% less NOx (nitrogen oxides) than current Tier II marine diesel-driven vessels. When the vessels travel outside ECAs, the IMO Tier II standard – which is equivalent to a 20% reduction in NOx Tier I emission standards – will need to be met.

Another important date in the environmental calendar is 2018. This is when the IMO will publish a fuel availability study specifying whether a global 0.50% limit for

SOx (sulphur oxides) emissions will enter into force in 2020 or 2025.

If it is the former, the implications for yacht owners are considerable and could mean a marked increase in operational costs for vessels operating on distillate fuels.Lloyd’s Register’s Senior Emissions Specialist, Max Wu, says: “Yacht and emission abatement system manufacturers are facing greater challenges from stricter emission regulations.”

LR has produced new guidelines and updated technical information that gives full support to yacht owners’ investment decisions. We also have our own emission abatement system rules and LR’s Type Approval teams can help and support system manufacturers get their products type approved. The LR guidance is available to download at www.lr.org/eca.

In the past two years owners have been turning to hybrid and battery power alternatives to meet the new emissions standards. Lloyd’s Register has been involved with several hybrid yacht projects recently. We feature one of them, the diesel-electric

powered superyacht Savannah, on pages 8 and 9 of this issue of Yacht Focus.

However despite recent technical advances, space still poses a problem for yacht-builders. “One of the biggest challenges for builders is space restrictions i.e. how do they get the required abatement equipment – which is not available yet for the engine types mainly used on yachts – installed and fitted in the limited engine room space that is available. The majority of the industry is already fully aware of the requirements but is struggling with getting the equipment fitted in time and approved,“ says Wu.

“LR is working hard with shipyards, engine manufacturers and exhaust gas abatement system manufacturers to get the systems certified,” he added.
