In May we welcomed Luke Parnell as our new Technical Superintendent, playing a pivotal role in overseeing and managing the maintenance of our vessels.

Chief Executive Stuart Reid said:

“Luke’s familiarity with our current vessels and operations, as well as experience with new builds, will be a real asset for the future.”

Earlier this month, Luke visited Piriou’s shipyard in Vietnam to familiarise himself with Scillonian IV and Menawethan. He will return at the end of August for a two-week period, providing cover for Chris and Peter during their annual leave.

During this visit, Luke will oversee key stages of progress. On Scillonian IV, he expects to see the completion of welding installation and integrity testing of the starboard fin stabiliser, as well as the final inspection of Void 1 before it is sealed for the next five years. He will also check on the installation of the floating floor on Deck 2, which is on course to be completed during his time in the yard. The main gearbox preliminary alignment should also be finalised, with full alignment scheduled once the vessel is afloat.

On Menawethan, Luke will attend the final inspection of the propellers and tailshafts, while advanced systems testing continues. Both the compressed air system and the sewage vacuum system are due to be presented for inspection by Owners and Class. Inspections of the anchor chain locker and pallet lift are also planned. Externally, the final topcoat of hull paintwork should be completed during his stay.

Earlier this month, Stuart Reid travelled to Vietnam for an important stage in the vessel build. His visit included time at the Piriou shipyard to inspect progress on both vessels, as well as a stop at the furniture manufacturing factory to review materials and the quality of construction for the passenger lounges furniture and interior outfitting.

It was also a valuable opportunity to spend time with project managers Chris and Peter, who have been based in Vietnam for the past 14 months. Seeing first-hand the strong relationships they’ve built with the workforce was a highlight, and we’re proud of the professionalism and commitment they continue to bring to the project.

Since Stuart’s last visit, the transformation has been remarkable: hull units fully integrated, staircases and engines in place, windows being installed, and electrical teams laying kilometres of cabling each week.

Here, Stuart tells us a bit more about his trip…

What was the purpose of this trip?

I was really excited to be returning to Vietnam 14 months after my last visit. We are in the middle of a very busy season at the Steamship Group so my time in Vietnam was short but I wanted to achieve three aims: to meet with our project team on the ground, to see the progress on both vessels for myself, and to visit the workshop where the interiors for the ships are being built.

Our project managers Chris Lingham and Peter Broad have spent the last 14 months in Vietnam and although we speak via video call weekly, they are part of the Steamship Group and it was an opportunity to catch up face-to-face both professionally and socially and make sure they are enjoying their time in Vietnam.

Chris, Peter and I visited the furniture manufacturing factory in Ho Chi Minh to undertake a final inspection and approval of the quality and design of the interior materials of our new vessels. The factory had prepared interior sections of each new vessel to show the construction and materials being used.

The factory has a reputation for delivering outfitting for superyachts and this can clearly be seen on the quality being delivered for our own vessels which is to a very high standard. The project team has been involved in the selection of the interiors from the inception of the project picking the type, colour and quality of all materials. This was an opportunity to see the interiors prior to them being delivered for fit out and we provided feedback on some items which have been well received by Piriou and adjusted prior to delivery to the shipyard.

What are the key differences or changes you noticed since your last visit in June 2024?

One thing which hasn’t changed since the last visit is the culture and standard of the shipyard. The yard remains spotless and highly professional with a safety-first culture. The workforce, of which there are about 250 on site, are a credit to Piriou. They are hard-working, professional and enjoying being part of this important project.

It was 14 months ago when I was last at the shipyard for the steel cutting ceremony and other members of the project team have visited the site in between these dates. On my last visit I inspected the storerooms, which held the large quantities of certified steel ready to be cut and integrated to form our two new vessels. Fourteen months later we now have all units of the ship completed and integrated into the shipyard dock. Staircases are integrated so you can walk through the vessel as if you were a member of the crew or passenger. Engines and gearboxes are in position. Windows are being installed. One of the most impressive sites was the large quantities of cabling being implemented into both ships. Piriou electrical teams are laying 5Km of cables per week which is incredible.

How was it seeing the team on the ground?

It was great to catch up with Peter and Chris. Although we have a video call weekly and regularly exchange emails and WhatsApp through the week it is always better in person. They are highly a professional team and the success of the project to date is a result of their dedication to our objective to deliver vessels for the community.

As we walked around the shipyard and inspected the vessels it is evident that Chris and Peter have excellent working relationships with the entire workforce. Their regular communication with the workforce and the levels of respect shown to them are just a couple of the many reasons why our partnership with Piriou is going so well.

Very well. Chris and Peter have separate apartments in District 7, about a 20-minute journey from the shipyard. District 7 has a large ex-pat community as well as many professional skilled workers. The shop, leisure and restaurant facilities in the area support comfortable living. I noticed when travelling with them in taxis that they have started to pick up phrases in Vietnamese for communication.

The work that Peter and Chris are undertaking is also physically demanding. Temperatures in the shipyard were around 35 degrees with high humidity. Put on a fire retardant boiler suit, gloves, safety hat and safety boots means this is energy sapping work as you climb around the ship, crawl through ballast tanks and move up and down ladders. Peter swims every night after work and Chris attends the local gym to maintain a very high standard of fitness.

What were your main takeaways from this trip?

The volume of quality work that has been undertaken in just 14 months. The shipyard is very busy and active with more than 250 skilled workers being co-ordinated by a group of experienced managers. Chris and Peter take daily photos of the build progress which are shared with me and the project team but seeing the vessels in Vietnam come to life since we started this project in 2019 is inspiring and a proud moment for the Company. I am confident that these new vessels will be transformational to the level of service we provide to the community and our visitors and I am already looking forward to their arrival in Scilly.

What’s the next major milestone?

The next major milestone will be the Menawethan’s launch from the dock, which will happen in October. The launch will not be a traditional launch. Instead on the day of the launch the dock will slowly fill with water and once afloat, Menawethan will exit the dock. This precision undocking process is to prevent disturbance to Scillonian IV which is being constructed in the same dock. Once Menawethan has exited the dock she will come alongside one of the berths in the shipyard and start her commissioning followed by sea trials at the end of the year.

As the vessels move closer to their commissioning and trial phases members of our management team and crew will start making visits to our new vessels. Our Marine Superintendent Tom Weise and Scillonian III Master Dave Redgrave will be visiting the shipyard this Autumn. The purpose of their visit will be to undertake planning for crew familiarisation training later in the year.

Today (June 25th 2025) marks exactly one year since building work officially began on the Isles of Scilly Steamship Group’s landmark project to bring two new vessels to the lifeline service.

The Isles of Scilly Steamship Group (ISSG), the primary provider of passenger and freight transport to the remote Isles of Scilly, is investing £40m in the passenger and freight vessels, Scillonian IV and Menawethan.

The first steels for the new ships were cut during a ceremony at Piriou’s shipyard in Ho Chi Min City, Vietnam on 25th June 2024 – marking the launch of what has become a remarkable shipbuilding journey.

Twelve months later, all hull blocks for Scillonian IV and Menawethan are complete.

Equipment installation is ongoing, and includes intermediate tailshafts; ventilation fans and trunking; sewage treatment and vacuum toilet systems; refrigeration units, air conditioning, domestic hot water tanks and more.

Work is now starting on the interiors of the vessels. Windows have started to be fitted to wheelhouses to make interiors watertight and attention is now turning to the installation of operational piping and staircases.

In another major milestone, Scillonian IV’s gearboxes and engines have been lifted into place this week.

Stuart Reid, Chief Executive of the Isles of Scilly Steamship Group, said: “This week we hit another installation milestone with Scillonian IV’s gearboxes and engines being lifted into place through a temporary opening. The gearbox, built in Germany, will reduce shaft speed between the main engine and the controllable pitch propeller, and includes a clutch mechanism allowing the main engine to be disengaged in favour of electric drive – supporting hybrid propulsion and fuel efficiency and be more environmentally efficient.

“Following this, the V12 diesel main engine, manufactured in Belgium by ABC, was lifted into place – the first of two 350-horsepower engines powering the vessel, producing 2652kw of power at 1,000rpm.

“We are proud of the progress that’s been made in a year. Our team, shipbuilders and partners have worked tirelessly to keep the project on track and we are all looking forward to delivering these state-of-the-art ships to serve our passengers and freight customers.”

Scillonian IV and Menawethan are being built by Piriou, and are on schedule to be delivered in 2026 to meet the travel and freight requirements of the Isles of Scilly for generations to come.

The new vessels will feature a range of new technologies, helping to improve resilience, comfort and reliability.

Scillonian IV will carry up to 600 people (a 24% increase on current levels) whilst reducing journey times. It will feature roll and pitch reduction systems, to enhance passenger comfort, and is designed utilising modern propulsion technologies that improve efficiency and reduce environmental impact. The vessel is also designed to integrate further enhancements as technology develops.

Menawethan will also include a range of improvements on the current vessel, including a much-enhanced cargo capacity and an improved capacity for perishable, chilled and frozen goods, meaning that supplies can be transferred between the mainland and the islands more reliably all year round. The freight vessel will incorporate a passenger lounge with accommodation for 12 passengers.

We were proud to be named Business of the Year at the 2025 Maritime UK Awards in June.

This recognition came as we marked one year since the first steel was cut for our new vessels, Scillonian IV and Menawethan – a major milestone representing the biggest investment in the Isles of Scilly’s transport in a generation.

The award celebrated our commitment to innovation, advanced technology, and excellence in building these state-of-the-art vessels. It was a proud moment for everyone involved at the Steamship Group and reinforced our dedication to delivering a sustainable, modern fleet that will serve the community for decades to come.

As 2024 comes to a close, we review what has been a historic year for the Isles of Scilly Steamship Group’s New Vessels Replacement Project.

It began in January, when we signed landmark contracts with shipbuilder Piriou to bring two new vessels into service on the Penzance to the Isles of Scilly route in 2026.

Building work officially began on Scillonian IV and Menawethan in June, with the first steels being cut during a special ceremony at Piriou’s shipyard in Vietnam. This important milestone was attended by senior company executives from ISSG and Piriou, including our CEO Stuart Reid.

Since then, substantial progress has been made in the build process and in November, we proudly marked the official “birth date” of the two new ships with a keel laying ceremony.

Guests included British Ambassador to Vietnam, Iain Frew; British Consul General, Ms. Alexandra Smith and her French Counterpart and Mrs Emmanuelle Pavillon-Grosser.

Dignitaries were accompanied by senior management from both shipbuilder Piriou and ISSG. As part of the occasion, a coin was laid in the keel of each vessel, which is a shipbuilding tradition. The ceremony is designed as a kind of blessing, bringing good fortune to the ship and its crew.

Scillonian IV and Menawethan are being built alongside each other, to ISSG’s detailed specifications, by Piriou’s expert teams of engineers and fabricators. The build is being overseen in Vietnam by ISSG project managers, Chris Lingham and Peter Broad, who relocated to Vietnam in June and will remain there until the vessels have left the shipyard.

Now, five-and-a-half months into the build, notable progress has been made on both ships, with about 40% of Scillonian IV’s hull structures and 70% of Menawethan’s hull structures being fabricated.

A ceremony attended by dignitaries has marked the official ‘birth date’ for our two new vessels. This significant milestone in the build process has been recognised for centuries as the official ‘birth’ of any new ship and is an important point in time for the Scillonian IV passenger ferry and the cargo vessel, Menawethan.

Invited guests attended Piriou’s shipyard in Vietnam on November 6th to officially mark the moment, while dignitaries from Britain and France were all present. British Ambassador to Vietnam, Iain Frew, attended the ceremony, along with British Consul General, Ms. Alexandra Smith and her French Counterpart, Mrs Emmanuelle Pavillon-Grosser.

Dignitaries were accompanied by senior management from both shipbuilder Piriou and ISSG. As part of the occasion, a coin was laid in the keel of the vessel, which is a shipbuilding tradition. The ceremony is designed as a kind of blessing, bringing good fortune to the ship and its crew.

Modern construction methods mean that ships are now built in blocks, whereas in the past ships were literally built from the keel up. The ceremony is now recognised as the point at which blocks are joined together. This ceremony follows the ‘steel cutting’ ceremony for the new ships, which took place earlier in the year.

Vessels are designed and built according to rules and regulations applicable for the type of vessel. Classification societies such as Lloyds Register develop technical standards and rules for the construction and survey of ships and their machinery, enabling compliance with International regulations. The international Maritime Organisation (IMO) is a specialized agency of the United Nations responsible for regulating shipping. The international framework for regulating ships is achieved through conventions, such as ‘Safety of Life at Sea’ and ‘Prevention of Pollution from Ships’ which are implemented by the maritime authority for each member state, with the support of classification societies. The maritime authority in the UK is the Maritime and Coastguard Agency (MCA), which is an executive agency of the UK Department for Transport.

The designs for the new vessels are submitted to Lloyds Register and the MCA to verify compliance with the rules and regulations and attain approval. Surveyors from Lloyds Register and the MCA will survey the ships during the build and subsequent vessel trials to verify compliance and subsequently during periodical surveys, throughout the life of the ship.


Piriou-choosen-shipyard-1200x807.jpg

Well Established

Piriou is a long-established ship builder with over 50 years’ experience building more than 600 vessels. It has over 1,400 highly skilled employees, including an in-house design team and production facilities in Europe, Africa, and Asia. Piriou has a strong balance sheet with an annual turnover of over £300m. Appointing Piriou comes after months of thorough evaluation, technical questioning and site visits to France and Vietnam, as part of the Group’s due diligence processes.

Similar ship builds

Piriou is a French ship building organisation with headquarters in Northwest France, approximately 100 miles from the Isles of Scilly. Piriou has built highly complex vessels with modern and low-emission propulsion systems. The Piriou project team was recently involved in a ferry design and build which services an off island community in Western France. The vessel, the Oya III, has stabilisation fins and has many similar operational characteristics to our existing vessels.

Proven ability

We have a complex project and Piriou has the necessary experience of delivering similar vessels with relevant technical expertise. Piriou has demonstrated that it can deliver the specification within our agreed budget and provide the necessary contractual requirements to protect our investment. Unfortunately, neither of the UK shipyards could meet all our requirements.

Design and construction

Working alongside Piriou, we have commenced detailed design work with the intention of signing contracts later this year for the new Scillonian IV passenger ship and a new cargo vessel to replace Gry Maritha. Construction of both vessels will commence in Piriou’s Vietnam shipyard in spring 2024. The vessels will then be transferred to Piriou’s shipyard in France for commissioning and testing and will be delivered for the 2026 season.
