Marine Aluminum Cases: IEC 60092 & DNVGL

A Kongsberg Maritime EM2040 multibeam echosounder ($50,000-$80,000) shipped from a marine electronics OEM facility in Kongsberg to an offshore survey vessel in Aberdeen arrived with a damaged transducer connector. The cause? A standard wooden crate with 25mm of loose-fill polystyrene that shifted during sea freight, allowing the 25kg echosounder to move 15mm inside the crate and impact the crate wall during a 12g handling drop at Aberdeen Harbour. The repair required a replacement transducer connector ($3,500), a full re-calibration of the echosounder ($8,500 in engineering time), and a 3-day delay in the offshore survey vessel’s deployment schedule. The survey vessel’s delay cost was $25,000 per day (a typical offshore survey vessel has $15,000-$50,000 per day in delay costs for deployment downtime, including labor, equipment rental, and survey delays)—so the total cost of that damaged transducer connector was $87,000.

Marine equipment spans the entire maritime system: from navigation equipment (GPS receivers, chart plotters, radar systems, AIS systems, compasses, gyrocompasses, echo sounders, multibeam echosounders, side-scan sonars, sub-bottom profilers) that navigate vessels, to communication equipment (VHF radios, HF radios, satellite communication systems, marine VSAT systems, marine VSAT antennas, marine VSAT modems, marine VSAT routers, marine VSAT controllers, marine VSAT sensors) that connect vessels, to sonar and acoustic equipment (fish finders, sonar systems, acoustic Doppler current profilers, acoustic release systems, acoustic modems, acoustic transducers, acoustic hydrophones, acoustic arrays, acoustic controllers, acoustic sensors) that detect underwater objects, to marine power equipment (marine batteries, marine inverters, marine chargers, marine power distribution units, marine power supplies, marine generators, marine transfer switches, marine power monitoring equipment, marine power quality analyzers, marine surge protectors) that power marine equipment, to marine safety equipment (life rafts, life jackets, EPIRBs, SARTs, fire extinguishers, safety cabinets, gas detectors, oxygen analyzers, carbon monoxide detectors, first aid kits) that ensure marine worker safety, to marine monitoring equipment (environmental monitoring systems, water quality monitoring systems, weather monitoring systems, vibration monitoring systems, structural health monitoring systems, DCIM systems, BMS systems, monitoring controllers, monitoring sensors) that monitor marine operations. What unites them is that every piece of equipment is part of a system where a single failure can cause a vessel outage (which can cost $10,000-$100,000 per day for marine vessels), a safety issue (from equipment malfunction, which can cause vessel accidents or marine worker injury), or in extreme cases, a marine equipment recall (which can cost $1,000,000-$50,000,000 for marine equipment companies). The transit case isn’t packaging—it’s the first line of defense against equipment damage during transport, and it must be specified to the same engineering rigor as the equipment it protects.

Regulatory Framework: IEC 60092, DNVGL, and Marine Standards

Marine equipment transport cases must support compliance with a complex web of standards. For marine electrical installations, IEC 60092 (Electrical installations in ships) specifies electrical installations in ships, including marine electrical design, marine electrical installation, marine electrical operation, and marine electrical maintenance, and the transit case must protect marine equipment without compromising its electrical features (including electrical safety, electrical performance, and electrical reliability). For marine classification, DNVGL (Det Norske Veritas Germanischer Lloyd) specifies marine classification requirements for vessels and offshore installations, including vessel design, vessel construction, vessel operation, and vessel maintenance, and the transit case must protect marine equipment without compromising its classification features (including structural integrity, fire safety, and environmental protection).

For marine environmental testing, IEC 60068 (Environmental testing) specifies environmental testing for electrical and electronic products, including temperature testing, humidity testing, vibration testing, shock testing, and salt mist testing, and the transit case must protect marine equipment without compromising its environmental features (including temperature resistance, humidity resistance, vibration resistance, shock resistance, and salt mist resistance). For marine EMC (Electromagnetic Compatibility), IEC 60092-507 (Electrical installations in ships—Part 507: Other equipment—Electromagnetic compatibility) specifies electromagnetic compatibility requirements for marine electrical installations, and the transit case must protect EMC-sensitive marine equipment without compromising its EMC features (including electromagnetic shielding, electromagnetic filtering, and electromagnetic grounding). For marine fire safety, SOLAS (International Convention for the Safety of Life at Sea) specifies safety of life at sea requirements for vessels, including vessel safety, vessel fire safety, and vessel lifesaving, and the transit case must protect marine equipment without compromising its fire safety features (including fire suppression systems, fire detection systems, and fire interlocks). For marine corrosion protection, ABS (American Bureau of Shipping) specifies corrosion protection requirements for marine vessels and offshore installations, and the transit case must provide corrosion protection for corrosion-sensitive marine equipment (including 316 stainless steel hardware, corrosion-resistant coatings, and continuous silicone gaskets for IP67 sealing). For marine vibration, ISO 6954 (Mechanical vibration—Guidelines for the measurement, reporting and evaluation of vibration on merchant ships) specifies guidelines for the measurement, reporting and evaluation of vibration on merchant ships, and the transit case must protect vibration-sensitive marine equipment without compromising its vibration features (including vibration isolation, vibration damping, and vibration monitoring). For marine temperature, IEC 60092-301 (Electrical installations in ships—Part 301: Equipment—General and regulations) specifies general and regulations for marine electrical equipment, including temperature requirements for marine electrical equipment, and the transit case must protect temperature-sensitive marine equipment without compromising its temperature features (including temperature resistance, temperature monitoring, and temperature control).

Case Design Specifications and OEM/ODM Capabilities

Our standard marine equipment case specification includes: 2mm thick 5052-H32 aluminum panels (or 3mm for heavy-duty applications over 50kg payload, or 4mm for marine navigation equipment that must meet structural requirements), Type III hardcoat anodized (25-50μm) plus polyester TGIC powder coating (60-80μm) in matte black, gray, or custom color (Type III anodizing is preferred for marine applications, as it provides better corrosion resistance than Type II anodizing); continuous silicone gaskets (Shore A 50-60) providing IP67 sealing (IP67 is standard for marine applications, for protection against dust, moisture, and salt spray); 316 stainless steel hardware (latches, hinges, handles, rivets)—316 stainless steel is mandatory for marine applications, as it provides superior corrosion resistance in salt spray environments; CNC-cut closed-cell XLPE foam (40-80 kg/m³, customer-specified density based on payload weight and fragility) with ESD-safe option (surface resistance 10^6-10^9 Ω/sq); heavy-duty draw latches (Southco or equivalent) with rubber bumpers; folding side handles (for cases over 15kg) or top handle (for cases under 15kg); stacking corners (recessed, for secure stacking); and a waterproof document holder (A4 size, inside lid).

Every marine equipment case we build is custom-sized to your equipment’s exact dimensions, with CNC-cut foam cavities that hold each component in its operational orientation. We don’t sell stock cases for marine equipment—because a 5mm gap means 5mm of potential movement during transport, and that’s where component damage, connector damage, and corrosion start. Typical lead time is 15-25 working days for first article (including design, prototyping, and customer approval), then 20-30 working days for production batches of 10-100 units. MOQ is 5 units per design. Pricing depends on size, complexity, and certification requirements.
