About Silvercrest Submarines
Worldwide Submarine Operations Since 1985
Company Overview
Silvercrest Submarines is a British submarine, ROV, and subsea engineering company with over 30 years of operational experience. We are not a manufacturer offering brochure specifications, and we are not a broker facilitating transactions at arm's length. We are operators - a company that has piloted its submarines to 230 metres in Scottish freshwater, taken film crews to sunken warships in the Baltic Sea, carried passengers across the Indian Ocean, and delivered the world's first mobile underwater bar. That operational record is the foundation of everything we do.
Headquartered in the UK with manufacturing facilities in Australia, Silvercrest Submarines has undertaken contracts across the Mediterranean, Arctic, Indian Ocean, Baltic Sea, Pacific, Caribbean, North Sea, and Scottish Lochs. Our work has spanned military support, scientific research, underwater tourism, super-yacht integration, commercial salvage, and international media production.
When a resort developer, superyacht owner, research institution, or defence operator engages us, they are not speaking to a salesperson - they are speaking to operators who have solved the same problems at depth.
Operational Heritage
The Loch Ness
Submarine Project
Our two-year Loch Ness operation gained international publicity and attracted submarine passengers from across the globe. Operating to depths of 250 metres (750 feet), the project offered a unique combination of scientific research, corporate entertainment, and educational tourism. The programme achieved what was claimed as a "World First" when we conducted a live satellite broadcast to ITV News at Ten, Canadian, German, and American television from the bottom of Loch Ness.
This project exemplifies Silvercrest's ability to manage long-duration programmes that serve multiple objectives simultaneously, generating substantial media coverage whilst delivering genuine scientific value and commercial viability.
The Windermere
Submarine Project
Baltic Sea
Sunken Battleship Dive
In the Baltic Sea, Silvercrest Submarines took a four-man film crew to the wreck of the Finnish coastal defence ship Ilmarinen at 100 metres. The Ilmarinen - flagship of the Finnish Navy - struck mines and sank on 13th September 1941, taking around 400 of her crew with her. The dive was part of an international documentary programme, conducted under full media scrutiny, in deep, cold water far from any support infrastructure. The technical demands were significant. What made this operation extraordinary was who came aboard: two of the ship's original survivors, then aged 80, dived with Silvercrest Submarines to the wreck to lay a wreath in memory of the men who had lost their lives there over half a century earlier.
That single operation illustrates the range of what Silvercrest Submarines is asked to deliver: precision diving to a specific historical target, management of a documentary film crew, extreme sensitivity to the human dimension of the mission, and the operational confidence to carry it all out without incident. It is the kind of commission that is not given to a company without a proven record.
Guinness Record
The World's First Mobile Underwater Bar
The world's first mobile underwater bar was produced by Silvercrest Submarines for an international client. Accommodating up to 12 guests and two crew members, the complex dives to a maximum depth of 61 metres (200 feet), maintaining a one-atmosphere passenger environment throughout. Guests experience a panoramic view of the underwater world through large-diameter viewports, served from a cocktail bar whilst powerful external lights illuminate the seabed during night operations.
No prior diving experience is required. No specialist knowledge. Simply an extraordinary setting.
This project demonstrates something that pure manufacturers cannot offer: the capacity to engineer a bespoke underwater solution from a client's brief, take it through design, construction, and deployment, and deliver something that had never existed before. The Underwater Bar is available for immediate deployment to a tourist resort or as an exclusive facility for a superyacht.
W-Sub3 Tenerife
A Proven Tourism Business
Abstract claims about capability mean far less than a proven, operating business. W-Sub3 is a 48-passenger tourist submarine operating year-round in Tenerife, in the Mediterranean. It carries approximately 44,000 passengers annually — a mature, commercially sustainable operation that has been delivering submarine tourism for years.
For investors, resort developers, or operators evaluating submarine tourism as a business proposition, W-Sub3 is not a concept or a projection. It is a working business with real passenger numbers, real operational costs, and real returns. Silvercrest Submarines designed, deployed, and has operated this business — and it is currently available for acquisition. There is no better proof of concept than a submarine already in the water, carrying passengers today.

Global Operations & Experience
The operational geography of Silvercrest Submarines spans most of the world's major ocean regions. In the Mediterranean, year-round submarine tourism operations have run continuously in Tenerife. In the Indian Ocean, two DNV-certified Mergo tourist submarines were placed into active tourism operations, carrying passengers in one of the world's most rewarding tropical dive environments. In the Baltic Sea, deep wreck operations and documentary filming have been conducted at 100 metres. In Scotland's Lochs, two consecutive multi-year programmes - Loch Ness and Windermere - delivered sustained operations in complex freshwater conditions. In the Arctic, research and commercial operations have been carried out in extreme cold-water environments. In the Caribbean, submarine deployments have supported luxury operations and superyacht integration. In the Pacific, research and scientific collaboration has been undertaken. In the North Sea, offshore energy and commercial support has been provided.
Industries served across these regions include tourism and resort operations; offshore oil and gas; scientific research; documentary and media production; luxury superyacht integration; defence and security; and marine construction and salvage.
This breadth of geographic and sector experience means that wherever an underwater project is located - and whatever its purpose - Silvercrest Submarines has relevant operational context to draw on.
Classification & Credentials
Silvercrest Submarines has direct, hands-on experience working with the world's principal classification societies. Our fleet has been certified by ABS (American Bureau of Shipping), DNV (Det Norske Veritas), Bureau Veritas (BV), Lloyd's Register, Germanischer Lloyd (GL), and IRS — not as a theoretical exercise, but through active certification programmes on operating vessels.
Examples from our own fleet illustrate the depth of that experience: TAURUS, our deep diving submersible rescue vehicle, holds ABS certification for operations to 1,500 feet (approximately 500 metres). The Mergo tourist submarines operated in the Indian Ocean carry DNV certification. The Spider Atmospheric Diving Suits, built by Slingsby Ltd, are certified by Lloyd's Register.
This classification experience means Silvercrest Submarines can advise operators and owners on the requirements of each classification society, help scope the survey preparation process, and coordinate with classification bodies on their behalf. Full details of our engineering and refurbishment services - including classification liaison - are available on the engineering services page.

Why Choose Silvercrest Submarines
The submarine and ROV industry includes companies that manufacture equipment, companies that broker transactions, and companies that operate vehicles. These are meaningfully different activities - and the distinction matters considerably when you are commissioning a significant underwater project.
A manufacturer knows how to build a submarine to specification. An operator knows what that submarine will actually encounter at depth - the thermal layers, the current variations, the failure modes, the crew decisions that cannot be predicted in a factory. Silvercrest Submarines has been operating submarines for over 30 years. That operational intelligence is embedded in every equipment recommendation, every engineering assessment, and every charter plan we provide.
Some companies specialise in a single market - luxury superyachts, or tourism, or inspection ROVs. Silvercrest Submarines operates across the full spectrum, from 48-passenger tourist submarines carrying 44,000 passengers annually to deep-water DSRV operations for scientific and military clients, to bespoke projects that have never been attempted before. That breadth means we can advise on the right asset for the right application, rather than fitting every enquiry to the product range we happen to sell.
And unlike a broker who facilitates a transaction and moves on, Silvercrest Submarines maintains long-term commitment to the operations we support. We have operated businesses, not just supplied them. We have taken passengers to depth, not just sold vessels that carry them. That is a different kind of relationship — and it is the relationship that clients who have worked with us return to.
