Marlin Submarines


Unit 42, Sisna Park Road, Plymouth, PL6 7FH

Organization's Description:

Marlin Submarines have been building submarines since 1986, specialising in the design and construction of autonomous Diesel-electric submarines for both commercial and tourist use.

In addition to the submarine projects, we have also undertaken the design and implementation of a wide range of underwater and industrial projects, both as prime and sub-contractors.

Details of our most recent design and build - S301, plus other major submarine projects, can be accessed through the links at the top of the page.


Marlin Submarines have a wealth experience in all aspects of manned submersible design and manufacture, including:

  • Pressure vessel design and construction,
  • Man-rated lifting and handling systems,
  • Lead-Acid and Lithium-Ion battery systems and charging equipment,
  • Air independent propulsion systems,
  • DC motive power systems,
  • Hydraulic and high-pressure gas systems,
  • Open and closed circuit atmosphere management and life support systems,
  • Pressure tolerant bearing design,
  • Control systems.
  • Systems can be designed and constructed under survey, and in accordance with the Rules of Classification Societies, including ABS (American Bureau of Shipping) and Lloyds Register of Shipping, or to the requirements of Pressure Vessel Codes including ASME PVHO (Pressure Vessels for Human Occupancy), PD5500 and ASME VIII.

Most of these technologies are appliciable to other areas of engineering. We welcome enquiries on any subject.
