ROV Systems & Subsea Engineering

Silvercrest Submarines supplies a comprehensive range of remotely operated vehicles and subsea engineering solutions, from compact inspection-class ROVs to heavy work-class systems capable of operating at 4,000 metres depth. The inventory includes vehicles suited to pipeline and cable inspection, scientific survey, offshore asset maintenance, salvage, and media production - available for purchase or charter, depending on operational requirements.

Complementing the ROV inventory, Silvercrest Submarines manufactures subsea electric motors at its Australian facilities.

Silvercrest/SME specialize in the bespoke manufacturing of submersible motors, HPU's, and pumps for use on ROVs, subsea trenchers, subsea ploughs, dredgers and water lift pump systems, for use in the offshore Oil and Gas and Telecommunications industries. We offer a range of submersible motors (5hp to 1500hp) with a choice of voltages (ranging from 380vac to 6600vac) for use subsea to depths of 6000msw. All of these motors are available in either SS316, Duplex, Super Duplex, or Hard Anodized Aluminium finish. We can also design and build motors to suit your individual and special project requirements. In addition, we refurbish, rewire, and service a wide range of submersible motors. Our product is excellent, our prices very competitive, and our delivery schedule the best in the industry.

Engineering services extend to ROV overhaul and refurbishment, motor rewinding and replacement, thruster upgrades, and full subsea system integration support. Whether you are procuring a new ROV system, refurbishing an existing asset or sourcing a replacement subsea motor, Silvercrest Submarines provides engineering expertise underpinned by decades of operational experience.

Over Three Decades of Operational Experience - Not Just Brokers

The distinction that sets Silvercrest Submarines apart from every other company in this sector is straightforward: we operate submarines, we don't simply sell them. Over more than three decades of continuous operations, Silvercrest Submarines has conducted submarine operations worldwide.

Provided submarines and crews for TV  documentary productions, and built and operated the world's first Underwater Bar.

Our operational heritage means that when Silvercrest Submarines advises on vessel selection, site suitability, crew training or business viability, that advice comes from our own operational experience.

Turnkey Business Solutions & Training

For operators seeking a complete submarine tourism or commercial diving business rather than simply a vessel, Silvercrest Submarines offers end-to-end turnkey solutions, and a fully operational support infrastructure - available as a complete business acquisition.

Silvercrest Submarines provides submarine pilot training delivered on-site worldwide, platform-specific to the vessel being operated. Training programmes are designed to equip operators and crew with the skills required for safe commercial operations under the relevant classification and regulatory framework. ROV operator training is available alongside submarine pilot courses for buyers acquiring combined systems.

Site surveys and operational feasibility studies can be conducted ahead of any purchase commitment, covering maritime and environmental conditions, regulatory requirements, infrastructure needs and market opportunity. Silvercrest Submarines has conducted such assessments across Mediterranean, Caribbean, Pacific and North Sea environments. Discuss your business requirements with our team, or review the full scope of submarine services available.

Worldwide Operations. Manufacturing and International Engineering Partnerships

Silvercrest Submarines operates worldwide, with manufacturing facilities in Thailand, Singapore, and Australia - where subsea electric motors are produced to a voltage range of 400vac to 6,600vac, covering depths from surface to 4,000 metres. International manufacturing partnerships spanning Europe and Asia enable Silvercrest to support new-build projects, including the T-26 24-passenger submarine design and the larger T-30 28-passenger configuration.

Classification society relationships with GL, DNV, Lloyd's Register and IRS ensure that every subsea vessel supplied by Silvercrest can be appropriately certificated for the regulatory environment in which it will operate.

Refurbishment programmes are available for operators seeking to extend the operational life of existing assets or to bring older vessels to current classification standards. Silvercrest Submarines supports submarine and ROV operators from initial feasibility through procurement, commissioning, training, ongoing maintenance and eventual disposal or refurbishment.
