Survitec has pioneered submarine escape technology, introducing full garment protection as alternatives to Davis Equipment and Steinke Hood as far back as 1952. Innovative, design based and fully validated improvements saw the introduction of SEIE Mk10 in 1990; the world’s first integrated Submarine Escape Suit & Liferaft combination. The SEIE MK11 continues this unrivalled tradition of innovation.

SEIE MK11 is a full body garment designed for pressurised tower escape with a fully integrated single seat liferaft.

• The only suit to exceed the known safe depth of escape of 240 meters having been fully instrument tested by QinetiQ to 310 meters.
• The SEIE Mk11 is able to provide complete peace-of-mind and security, using 30% less air than earlier designs.
• The only fully integrated system on the market today, proven to reduce the likelihood of end user CO2 saturation typically found in more segmented products.
• Through partnerships with HABETAS and ISEC, we are the only company capable of ensuring design and functionality optimisation for use with current hood inflation systems, providing future cost efficiencies with zero expense for the end user.

New advanced design offers increased protection and survivability

• Unique laminate liner offers increased thermal protection and durability.
• In-built lifejacket stole provides improved surface survivability.
• New 3 in 1 Polar Fleece Headover improves thermal management of head, neck and face regions.
• Improved Hood Inflation System.
• Non-slip thermal soles for added protection.
• Superflex Neoprene gloves improved dexterity and thermal properties. Stowed in external accessory pocket.
• A training model is also available, suitable for multiple use.

Unique approach improves functionality and product output

• Larger ascent hood view panel gives greater visibility during flood and ascent phases.
• Ascent hood includes patented “rip-zip” for rapid CO2 venting on the surface.
• Extended torso and leg adjustment straps give enhanced sizing control and the efficient gathering of excess material.
• Design changes to the ankle and foot profile allow easier donning while wearing navy issue footwear.
• The improved design shows in the overall improved comfort, fit and functionality of the SEIE MK11.
• The SEIE MK11 is capable of exceeding the known escape depth - tested (unmanned) to 310m and validated by QinetiQ.

Radical stole design optimises operational capability

• A new unique self-righting stole design has been developed to withstand twice the pressure of existing equipment.
• Patented Mk6 Automatic Stole Relief Valve enhances stole inflation, guaranteeing the stole/hood remains fully inflated all the way to the surface.
• Improvements to the YPFC and enhanced hose positioning, improves air flow and overall operational performance of the ascent stole, allowing for controlled stole / hood inflation.
• Integral life jacket style stole provides over 170N buoyancy and increases freeboard. SEIE MK11 is suitable for surface abandonment negating the need for secondary equipment or storage.

Liferaft features:

• The new larger liferaft design enables the foetal position to be sustained for longer periods at sea.
• The inflatable floor provides improved insulation.
• Modern, lightweight, more durable fabrics have been selected throughout.
• Flame resistant fabric has been used for the outer valise material with an inner lining manufactured from a composite metallised polymeric film with encapsulated air gaps to protect the packed assembly.
• Heavy duty foil barrier material is used to hermetically seal the assembly from external liquid damage and incorporates a new quick release zip design.

Packed dimensions - 345mm x 320mm x180mm.

Packaging and Storage

Thermal Liner – The thermal liner is packed in a separate hermetically sealed foil envelope to aid protection and logistics with a new metallised Polyethylene Laminate material, giving excellent thermal protection and high durability. Can be worn over normal service wear.

Valise – Durable flame resistant fabric is used for the outer valise material with an inner lining manufactured from a composite metallised polymeric film with encapsulated air gaps to protect the packed assembly.

Storage – Optimised for on vessel storage - standard configuration packed dimension.

Sizes can be configured to suit customer requirements.
