What Libra-Plast does
Libra-Plast AS is a Norwegian manufacturer of marine doors, hatches, and storage solutions serving the global maritime industry since 1954. Founded by Albert Lillebø on Norway's west coast in response to recurring shipwrecks, the company operates approximately 100 employees across two production facilities in Hareid, Norway and Saldus, Latvia. It supplies commercial shipyards, offshore operators, and naval/defense vessel builders worldwide with IMO-compliant hinged steel, aluminium, and composite (GRP) bulkhead doors and hatches, plus customized storage units, bridge wing consoles, and battery boxes. Distribution combines direct enterprise sales, a global agent network spanning 15+ countries across four continents, and a web-based product configurator that feeds quote-basket inquiries to the internal sales team.
The company's core technology is sandwich-composite marine door and hatch engineering, with DNV-GL and ABS Type Approval / MED certification across multiple product families (WRD, WRD-A, HDS, SLD, WTD, WRH, WTH, SLH). Libra-Plast was the first company in the world to receive DNV Type Approval for sandwich-composite weathertight doors in 1971, and has worked with GRP composite materials for marine applications since 1957. The product range covers A0/A60 fire integrity and water integrity grades from spraytight through watertight (up to 30m pressure head), with products pressure-tested with major classification authorities (DNV, BV, Lloyds, Rina, ABS). Each unit is custom-engineered to customer specifications, supported by 3D CAD visualisation and complete drawing sets accompanying all quotes.
The business model is built on custom quote-based pricing for every inquiry, with multi-year frame agreements providing recurring volume contracts. Revenue is generated primarily from custom-built marine doors and hatches (the dominant stream), supplemented by spare parts (gaskets, gas cylinders, hatch holders, adhesives, sealants, locks, portholes) sold through the aftersales team, and customized storage units for survival equipment and marine instrumentation. The December 2024 strategic 3-year frame agreement with Damen Shipyards Group — covering all external doors and hatches for the Workboats division (~100 vessels/year, ~€3B Damen production value) — represents the company's largest disclosed enterprise contract. Frame agreements are negotiated at corporate level by the CEO and Sales & Marketing Director, while global agent commissions handle local market coverage. The catalogue spans 152 products, and the company maintains GDPR compliance and Norwegian Transparency Act (Åpenhetsloven) disclosure.

Libra-Plast product offering
Product offeringCore offering
Libra-Plast AS designs and manufactures IMO-compliant, custom-engineered marine doors, hatches, and storage units in steel, aluminium, and GRP composite materials for commercial shipyards, offshore operators, and naval/defense vessel builders. The offering spans Type Approved weathertight and watertight bulkhead doors and hatches with multiple fire and water integrity ratings, plus complementary marine storage solutions and aftermarket spare parts, configured to customer specifications via an online product configurator.
Product overview
Libra-Plast AS is a single unified maritime product portfolio organised as one core platform of IMO-compliant marine doors and hatches with an integrated storage and spare-parts catalogue — rather than separate platforms. The offering is structured into three main product categories: Doors (sub-divided into ACD Accommodation Doors, SSD Side Shell Doors, HDS Sandwich Fire Doors, WRD Heavy Duty Doors, WTD GRP Doors, and SLD Sandwich Doors), Hatches (WRH Heavy Duty Hatches, WTH GRP Hatches, SLH Sandwich Hatches, SSH Side Shell Hatches), and Storage (SC-series customised storage units, BWC-series Bridge Wing Consoles, BB-series battery boxes, C-series and OL-series storage cabinets, plus LR-series and L-series life-vest/suit containers). Underpinning all categories is a configurable product range with materials in steel, aluminium, GRP/composite or stainless steel, integrity ratings (spraytight, weathertight, watertight, A0/A60 fire), and a complementary Spare Parts catalogue (gaskets, gas cylinders, hold-open hooks, windows, portholes, adhesives, locktite, firestop sealants, cylinder cover caps).

Libra-Plast competitors and assessment
Company assessmentBroad incumbents
