Technical details
Producer:	Ocean Submarine (NL)

Introducing the first luxury submarine with maximum manoeuvrability
Neyk Submarine offers speed, comfort and maximum customisation. Construction is underway on the first luxury submarine to feature an interior from the private jet industry. The product of eight years of research & development, Ocean Submarine in the Netherlands is teaming up with leading experts from around the world such as Rolls Royce, MTU and Bosch to create the Neyk Submarine. Built in a modular construction in high-yield steel to a design optimised by NASA, the submarine will offer an unprecedented degree of luxury and customisation, speeds of up to 15 knots and can carry as many as 20 passengers.

The Neyk Submarine has a fully pressurised hull and will be exceptionally manoeuvrable. It brings together high-end technologies and components that have been proven in practice around the world in a submarine which is outfitted in bespoke, state-of-the-art facilities in the Netherlands.

A compact and lightweight structure offers various options in terms of finding the right location on a superyacht while also enabling the craft to reach speeds around three times higher than conventional private subs. Customisation options include fitting landing gear so that the sub can come to rest on a beach, adding a dedicated diver lockout chamber, and transforming the nose area into a 270-degree underwater observation room.

The first Neyk Submarine will have an overall length of 19 metres (63ft),a maximum displacement of 100 tonnes and be able to take up to 12 passengers to depths of 150 metres (500ft). It will have large panoramic viewports on top and three acrylic viewports on either side, as well ascomfortable seats, a bar, a library and a complete galley.

Stringent testing regime
Neyk Submarine spent two years on the test programme, developing an ultramodern teardrop body by using a range of aids from PCs right up to supercomputers. The next stage was to test ten models in a development programme.

Three models were used in manoeuvring simulators, a high-speed towing tank and deep water towing tanks. The moving dynamic forces which come into play were tested in addition to the static forces (weight and buoyancy), the dynamic forces produced by the submarine's hull shape and action of the rudders, and the fore and aft hydroplanes, which control the submarine's position and motion in the horizontal and vertical planes respectively.

Extensive tests were conducted for the main propulsion system to discover the optimum position for the engines outside of the pressurised hull. The virtually silent electric engines are placed in pods either side, specially designed to give the propellers up to five percent additional efficiency and provide extra cooling at low speed. The revolutionary design also provides for low drag and a very low underwater noise signature.
