Marine Immersion Thermal Protective Suit Immersion Suit For Shipboard Emergency

Product Specification

Product name: Marine Immersion Thermal Protective Suit (Immersion Suit for Shipboard Emergency Use)

Overview:
A SOLAS‑style, fully integrated immersion suit engineered to reduce the risk of hypothermia after accidental immersion in cold water. The suit combines high‑buoyancy, low‑water‑absorption CR neoprene with a watertight design, built‑in insulated boots and gloves, and high‑visibility safety features. Designed for merchant ships, offshore platforms, fishing vessels, coast guard, and passenger ferries as mandatory survival equipment.

Key functions and benefits:

• Thermal protection: Closed‑cell CR neoprene traps insulating air and minimizes convective heat loss, helping maintain core temperature during prolonged immersion.
• Buoyancy and flotation: The foam structure provides inherent buoyancy; integrated buoyancy aids and head support help keep the airway clear in the water.
• Watertight integrity: Glued‑and‑stitched seams with internal/external taping and water‑resistant zipper reduce flushing and heat loss.
• Integrated PPE: Attached 3‑finger mitts and molded boots reduce donning time and prevent loss of components.
• High visibility and rescue readiness: Bright international orange/red outer, retro‑reflective tapes per IMO visibility zones, and whistle/light provisions improve detectability day and night.
• Rapid donning: Oversized entry, guidance prints, and rugged pullers allow most users to don within 60 seconds with minimal assistance.
• Durable, low maintenance: Oil/salt/UV‑resistant outer jersey or coating for long service life in marine environments.

Typical applications:

• SOLAS carriage requirements on cargo and passenger vessels
• Offshore rigs and wind farms
• Rescue boats and coast guard operations
• Commercial fishing and polar/temperate routes
• Helicopter transfer standby

Technical specifications (standard, customizable to flag/owner requirements):

• Core material: CR (chloroprene) closed‑cell neoprene, low water uptake
• Construction: Double‑lined neoprene or coated outer with glued + blind‑stitched seams; full seam taping
• Thickness: 5 mm typical (options 3–6.5 mm per water temperature class)
• Thermal performance: Meets thermal protection performance to limit body core temperature drop to ≤2 °C over 6 hours in 0–2 °C water when worn correctly with underlayers (exact results depend on standard/test protocol)
• Buoyancy: Inherent positive buoyancy; face angle and freeboard designed to keep mouth/nose above water
• Donning time: ≤60 s target with practice (spec varies by standard)
• Sizes: S, M, L, XL, XXL; stowable oversized versions available; customized tall/short options
• Outer color: High‑visibility red/orange; custom logo and vessel ID print
• Reflective: SOLAS‑grade retro‑reflective tape on head, chest, arms, and legs
• Closures: Heavy‑duty water‑resistant front zipper with storm flap; inner gusset for splash sealing
• Face seal: Smooth‑skin neoprene hood and adjustable face flap to reduce flushing
• Hood: Integrated thermal hood with spray shield; optional lifting becket
• Gloves: Attached 3‑finger mitts for warmth; textured palm for grip
• Boots: Integrated insulated boots with non‑slip marine outsole; reinforced instep and heel
• Harness/attachments: External lifting loop or D‑ring for rescue; crotch/waist belt to stabilize fit
• Accessories: Safety whistle fitted to chest; pocket for PFD light; option for SOLAS‑approved water‑activated light
• Storage: Vacuum or roll‑bag packaging with inspection window; ID label and instruction sheet
• Operating temperature range: Typically −30 °C storage to marine ambient; immersion performance validated per standard
• Compliance options:
  • SOLAS 1974 (as amended) LSA Code, IMO Res. MSC.81(70) with latest amendments
  • ISO 15027 immersion suit series
  • MED “Wheelmark” / USCG approval pathway where required
  • RoHS/REACH material declarations; AZO‑free dyes

Design and engineering notes:

• Fit and mobility: Patterned for emergency donning over work clothing; articulated knees and elbows maintain mobility inside liferafts.
• Flushing control: Smooth‑skin seals at face and wrists reduce water exchange; optional inner cuffs.
• Head support: Foam distribution in hood/neck increases self‑righting tendency and supports airway clearance in waves.
• Self‑righting: With proper buoyancy layout, the suit assists the user to turn face‑up quickly; optional inflatable pillow can be added if specified by the standard.
• Thermal strategy: 5 mm CR offers a strong balance of insulation and dexterity; colder routes may specify thicker foam or plush thermal lining.
• Service environment: Outer knit or coating resists diesel, hydraulic oil, UV, and abrasion common on decks.

Quality and testing:

• Water tightness: Hydrostatic or shower tests per IMO/ISO on production lots
• Seam strength: Peel/shear tests on glued/taped seams
• Buoyancy retention: Aged buoyancy tests after saltwater exposure
• Thermal manikin or human subject testing per relevant standard
• Visual and dimensional inspection; serial number traceability

Care, inspection, and service life:

• Routine checks monthly/quarterly: zipper operation, tape integrity, reflective condition, whistle/light function, size labeling
• Rinse with fresh water after drills; hang to dry in shade; avoid solvents and high heat
• Storage: Cool, dry, away from sunlight and ozone; keep in protective bag/locker near muster stations
• Replacement intervals: Follow flag/owner policy; typical service life 5–10 years depending on environment and inspection results
• Training: Conduct donning drills and familiarization per Safety Management System

Options and customization:

• Sizes with vessel‑specific color coding
• Company branding and unit numbering
• Integrated PFD light and AIS/PLB pocket
• Reinforced high‑wear panels (seat, knees)
• Buddy line, sprayhood, and lifting becket kits
• Child/teen and oversized models

Image notes:
