Projects
Silvercrest Submarines is a British company specialising in manned submarine and deep-diving submersible operations, with contracts performed worldwide. Over more than thirty years of active operations, the company has conducted scientific research, tourism, underwater filming, commercial survey, wreck exploration, military support, and specialist charter work across most of the world's major oceans — from tropical waters to the Arctic ice pack. The projects documented here represent a record of confirmed operational activity, drawn from Silvercrest Submarines' own archives. They are presented not as a sales exercise, but as evidence of the kind of experience and operational depth that distinguishes a working submarine company from those that simply manufacture or broker equipment.
The Loch Ness Submarine Project
The Loch Ness Submarine Project remains one of the most publicly documented submarine programmes in British history. Conducted over two summer seasons, the project combined scientific research, corporate entertainment, and educational tourism, taking passengers to operational depths of up to 800 feet (approximately 250 metres) in one of Scotland's most famous and atmospheric bodies of water. Sponsored by Swatch Watches, the programme logged one thousand dives over its duration — a volume that speaks to the operational reliability and consistency that serious submarine operators must demonstrate.
The project attracted international attention from the outset. Passengers travelled from across the world to take part, drawn by the unique proposition of a manned submarine dive beneath the surface of Loch Ness. Media interest was extensive and sustained, with coverage across British, European, North American, and Asian broadcasters. The programme's most celebrated technical achievement was a live satellite broadcast transmitted from the bottom of Loch Ness to ITV News at Ten, together with simultaneous broadcasts to Canadian, German, and American television networks — an achievement claimed at the time as a world first. Television productions that covered the project included Channel 5's "The Loch Ness Monster — The Ultimate Experiment", BBC Blue Peter, the BBC Really Wild Show, BBC Breakfast TV, GMTV, and Granada TV, amongst many others.
The Loch Ness programme demonstrated Silvercrest Submarines' capacity to sustain high-cycle public submarine operations safely and professionally over an extended period, whilst simultaneously managing complex media logistics at an international level.
The Windermere Submarine Project
Following the completion of the Loch Ness programme, Silvercrest Submarines undertook an eighteen-month submarine operation in Lake Windermere in England's Lake District. The primary focus of the Windermere Submarine Project was a systematic shipwreck hunt, combining scientific research objectives with an educational tourism operation that brought members of the public into direct contact with genuine underwater exploration.
The project was structured to serve two purposes simultaneously: to conduct methodical survey work in search of historical wrecks on the lake bed, and to offer the unique experience of participatory underwater exploration to passengers. The combination of authentic research activity and public engagement proved compelling, and the project attracted significant national media coverage throughout its duration.
The Windermere programme demonstrated Silvercrest Submarines' ability to design and sustain multi-purpose submarine operations over an extended period in inland freshwater environments, managing both the operational and public-facing dimensions of a complex programme concurrently. Like the Loch Ness project before it, it established a template for how serious submarine operators can generate commercial viability alongside genuine scientific activity.
Baltic Sea Wreck Expedition
One of the most historically charged operations in Silvercrest Submarines' record involved taking a four-man film crew to a sunken battleship lying at 300 feet (100 metres) in the Baltic Sea, in waters off Russia. The expedition formed part of a wider underwater documentary programme and required careful logistics for deploying a manned submersible in a challenging open-sea environment to a confirmed working depth.
What distinguished this operation from a standard wreck survey was the human dimension at its centre. Two of the original survivors of the sinking — both eighty years of age at the time — dived in the submarine to return to the wreck. Together with the Silvercrest Submarines crew, they laid a wreath in memory of the four hundred men who lost their lives when the vessel sank in 1944. The significance of the moment, in terms of both its historical weight and the operational demands it placed on the submarine team, required a level of sensitivity and professional competence that went well beyond routine submersible work.
The Baltic expedition illustrates the range of contexts in which Silvercrest Submarines has been trusted to operate: not merely for scientific or commercial purposes, but for operations where precision, reliability, and human respect were equally paramount.
Taurus DSRV — South Africa
The deep-diving submersible Taurus is one of the most capable vehicles in the Silvercrest Submarines fleet. Built in Vancouver by Hyco Inc and certified by ABS (American Bureau of Shipping), the Taurus has an operational depth of 1,500 feet (500 metres) and is equipped for a range of demanding underwater tasks. Its specification includes 36-inch diameter viewports, a seven-function manipulator arm, sonar, tracking equipment, and comprehensive external lighting. The payload capacity is substantial, allowing a wide range of cameras, scientific instrumentation, and tools to be fitted according to mission requirements. The Taurus is rated for DSRV (Deep Submergence Rescue Vehicle) operations, diver lockout, and general one-atmosphere work.
Following an extended refit programme, the Taurus was deployed to South Africa for diving trials conducted in collaboration with the South African Submarine Service, operating from their base at Simonstown. The South African coastline and surrounding waters hold approximately two thousand shipwrecks accumulated over several centuries, making the deployment a significant operational and historical undertaking.
The Taurus South Africa programme demonstrated Silvercrest Submarines' capacity to manage full-scale deep-submersible deployments in cooperation with national naval services — a category of work that demands the highest standards of technical preparation, crew competence, and equipment reliability.
Indian Ocean Tourist Submarine Operations
Silvercrest Submarines acquired and operated two Mergo tourist submarines — passenger-carrying submersibles designed specifically for the underwater leisure and tourism market — in the Indian Ocean. Each Mergo submarine is rated to carry ten passengers and one pilot to an operational depth of 300 feet (100 metres), with DNV (Det Norske Veritas) certification providing the independent safety assurance required for commercial passenger operations.
The internal specification of the Mergo submarines reflects the standards expected in professional tourist submarine work. Each passenger is provided with an individual 16-inch panoramic viewport, ensuring direct and unobstructed views of the underwater environment throughout the dive. The pilot operates from a large domed viewport that provides the situational awareness required for safe manoeuvring in proximity to reef and seabed features. Air conditioning maintains passenger comfort throughout the dive.
The Indian Ocean deployment placed Silvercrest Submarines in direct operational command of a dual-vessel tourist submarine programme in a tropical marine environment — a logistically demanding undertaking that required sustained maintenance capability, trained crew management, and consistent operational standards across both vessels over the duration of the programme.
Galapagos Islands — ComSub Charter
The ComSub is a two-man mini-submarine with a diving depth of 600 feet (200 metres). Lightweight and configured for straightforward transport by both road and sea, the ComSub is designed to be mobilised rapidly to remote dive sites — a characteristic that makes it particularly suited to charter deployments in locations where larger, heavier submersibles would present serious logistical challenges.
Silvercrest Submarines operated the ComSub on charter in the Galapagos Islands, one of the world's most ecologically significant and operationally demanding marine environments. The waters of the Galapagos archipelago present navigational and environmental complexities that require experienced submarine operators: strong currents, variable visibility, and sensitive marine habitats that demand precise piloting and operational awareness throughout any dive.
The Galapagos charter demonstrated the ComSub's versatility as a deployable platform and confirmed Silvercrest Submarines' ability to conduct professional submarine operations in remote, high-value natural environments where operational standards and environmental responsibility are equally non-negotiable.
Grand Cayman — Kirk Pride Wreck Survey
Off the coast of Grand Cayman, Silvercrest Submarines deployed two Perry submersibles to film the wreck of the Kirk Pride at 780 feet — a depth that places the operation firmly in the category of deep-water professional submarine work, well beyond the range of recreational diving and requiring the one-atmosphere systems for which Perry submersibles are designed.
The Kirk Pride filming operation was a technically precise undertaking, requiring the coordinated use of two submersibles to achieve the coverage and angles demanded by a professional filming brief at depth. Perry submarines are rated for commercial activities, scientific research, underwater filming, and search and salvage at depths to 1,000 feet (300 metres), and their use in this context reflected a considered match between platform capability and operational requirement.
The Grand Cayman survey is characteristic of the filming and wreck survey work that Silvercrest Submarines has undertaken throughout its operational history — combining deep-water technical competence with the specific requirements of documentary and research production in challenging underwater environments.
Super Yacht Submarine Deployments
The integration of a manned submarine into a super yacht programme represents one of the most demanding technical and logistical challenges in the luxury marine sector. Silvercrest Submarines has successfully placed luxury submarines aboard two of the world's largest super yachts, with a third super yacht charter also completed. These deployments enable the owners and guests of those vessels to conduct private submarine dives from the yacht platform at locations worldwide.
Each super yacht submarine deployment requires careful consideration of launch and recovery systems, deck space, crane or davit compatibility, tender logistics, and the specific operational profile required by the owner. Silvercrest Submarines manages the full scope of this process, from submarine selection and specification through to crew supply and operational support. The company offers luxury submarines in configurations ranging from two to ten passengers to meet the varying requirements of different super yacht owners.
The record of three super yacht deployments confirms Silvercrest Submarines' standing as one of the few operators with direct, proven experience of integrating manned submarines into the super yacht environment — a technically specialised field that very few submarine companies have the credentials to enter.
World's First Mobile Underwater Bar
Silvercrest Submarines produced what is believed to be the world's first mobile Underwater Bar for an international client. The concept was designed to provide a one-atmosphere underwater viewing and entertainment environment capable of accommodating up to twelve guests and two crew members, deployed to a maximum diving depth of 200 feet.
The Underwater Bar was constructed along the principles of established tourist subsea technology, incorporating a large passenger-viewing gallery with large-diameter viewports and luxury seating. Powerful underwater lights illuminate the surrounding seabed during night operations. A cocktail bar provides refreshments to guests during their dive. All passenger compartments are maintained at one-atmosphere pressure throughout the dive, meaning guests require no previous diving experience or specialist training.
The development of this concept required Silvercrest Submarines to apply engineering disciplines drawn directly from the company's experience with tourist submarine design and pressure vessel construction — adapting proven technology to an entirely new application. The Underwater Bar is designed for deployment at tourist resorts or as a permanent exclusive facility aboard a super yacht, and represents the kind of bespoke engineering capability that characterises Silvercrest Submarines' approach to specialised subsea projects.
Global Operations
Beyond the individual projects documented above, Silvercrest Submarines has conducted submarine and submersible operations across a range of additional environments and locations that together demonstrate the genuinely global scope of the company's operational history.
In the Arctic, Silvercrest Submarines has conducted diving operations beneath the ice pack — some of the most technically demanding submarine work possible, requiring meticulous pre-dive planning, precise navigation under a closed overhead environment, and absolute reliability from all systems. North Sea operations have included deployments of Pisces submersibles and LR submersibles, as well as work involving the Mobile Diving Unit (MDU) — platforms and systems associated with some of the most demanding commercial submarine work in the industry. Caribbean submarine operations and Indian Ocean deployments have provided further evidence of the company's capacity to operate across different sea states, climates, and regulatory environments.
In Southeast Asia, a Silvercrest Submarines crew undertook the refit of a forty-passenger tourist submarine — a large-scale engineering programme conducted in the field. The breadth of this record, from Arctic ice operations to tropical tourism programmes, from North Sea commercial work to remote island charters, reflects an operational history that is genuinely diverse. Silvercrest Submarines has operated in most of the world's major oceans and across a range of mission types that few submarine operators anywhere can match.
Media and Documentary Partnerships
Silvercrest Submarines has maintained an extensive relationship with international media organisations throughout its operational history. The company's activities have attracted coverage from broadcasters and news organisations across the United Kingdom, Europe, North America, Asia, and Australia, reflecting both the international interest in submarine operations and the consistent quality of the access Silvercrest Submarines has been able to provide.
The most celebrated single media achievement was the live satellite broadcast transmitted from the bottom of Loch Ness to ITV News at Ten, with simultaneous coverage reaching Canadian, German, and American television audiences — an event claimed at the time as a world first. This broadcast required the coordination of satellite uplink technology, subsurface communications, underwater filming and live production management during an active submarine dive, demonstrating a level of technical and operational confidence that few submarine operators could have delivered.
Among the many productions that have featured Silvercrest Submarines, the Discovery Channel's "Extreme Machines" programme provided particular exposure for the ComSub, presenting the vehicle to a global audience as part of a six-part series exploring transportation across land, sea, and air. Other confirmed productions include work with Paramount Pictures, CNN, ABC TV, NBC News, BBC, Sky News, Reuters, and numerous European and Asian broadcasters. The full list of media partners spans more than forty international outlets across five continents.
