Explore certified standard, open top, reefer, and high-cube units engineered for harsh intermodal transport and industrial deployment.
Unlike terrestrial intermodal containers governed exclusively by ISO 1496-1, Offshore Cargo Carrying Units (CCUs) operating in open maritime environments face extreme multi-axial acceleration, snatch loads, and corrosive wave spray.
Our offshore basket containers use high-yield micro-alloyed structural steel (Q345E / S355NL / S355ML) tested for Charpy V-notch impact performance at -20°C down to -40°C (minimum 27 Joules absorbed energy). This metallurgical control prevents brittle fracture failure modes when hoisting tubular goods, drill collars, and heavy bottom hole assemblies (BHA) in sub-zero Arctic and North Sea conditions.
Integrated lifting lugs are machined from forged or Normalized rolled structural plates with ultrasonic testing (UT Level II). In accordance with DNVGL-ST-E271 and ISO 10855-1, pad eyes are designed to withstand a Dynamic Amplification Factor (DAF) ranging from 1.3 to 2.4 depending on Gross Mass, ensuring zero localized plastification during heave-induced vessel transfers.
Surfaces undergo automated SA 2.5 shot blasting followed by dual-path anti-corrosion protection: hot-dip galvanization to ISO 1461 (nominal zinc coating thickness ≥ 100 μm) or high-build NORSOK M-501 System 1 epoxy-polyurethane marine coatings (DFT ≥ 280 μm), providing extended resilience against high-salinity spray, UV degradation, and constant abrasion from casing pipes.
Engineering transparency is fundamental to procurement planning. Below is our comparative technical specification and budgetary pricing matrix (FOB Tianjin/Shanghai) for offshore basket configurations.

From exploratory drilling in deepwater basins to offshore wind turbine maintenance, our specialized basket configurations solve complex logistics challenges.
Equipped with internal quick-lashing systems, nylon-cushioned wear strips, and low-profile partition stanchions, our tubular baskets protect premium API thread casings, drill collars, and downhole mud motors against mechanical shock, preventing multimillion-dollar drill string failures.
Designed for crew transfer vessels (CTV) and service operation vessels (SOV), our compact, lightweight offshore tool baskets facilitate rapid crane transfers to transition pieces, featuring non-sparking aluminum composite access ramps and anti-slip expanded metal flooring.
Engineered for Remotely Operated Vehicle (ROV) support vessels, these baskets incorporate integrated manifold mounting plates, hydraulic tie-down rails, and optional sacrificial anode tabs to mitigate electrolytic degradation during subsea immersion operations.
How CIMIC Group achieves cost efficiency without compromising marine structural reliability through automated robotics, mill integration, and digital supply chain architecture.
We leverage direct strategic relationships with tier-1 Chinese steel producers (Baosteel, HBIS), sourcing structural hollow sections and heavy plates with batch-level EN 10204 3.2 material test certificates (MTC), eliminating middlemen margins while verifying trace metallurgy and chemical compositions.
Critical load-bearing structural seams, pad eye penetration welds, and primary perimeter beams are executed with multi-axis automated robotic welding systems. Qualified under ASME Section IX and ISO 15614-1, these processes eliminate human fatigue-induced inclusions, achieving repeatable structural soundness verified via Ultrasonic Testing (UT).
With heavy manufacturing facilities situated roughly 100 kilometers from Tianjin Port and Suzhou logistics hubs, finished offshore basket containers are delivered directly to breakbulk and containerized berths without costly domestic overland freight transfers, cutting export transit times and carbon overhead.
Anticipating decarbonization mandates, hazardous zone safety criteria, and autonomous offshore asset telemetry.
Integration of ATEX Zone 1 / IECEx certified solar-powered telematics sensors directly within the container frame. Monitoring real-time 3-axis shock impacts, dynamic lift cycles, GPS coordinates during open-sea transit, and geo-fencing offshore supply bases.
Pioneering the use of Electric Arc Furnace (EAF) recycled high-tensile steel, cutting Scope 3 embedded carbon emissions by up to 58% per container unit. Supporting European and North American operators striving toward strict ESG decarbonization targets.
Developing hybrid basket frames with acoustic transponder release hooks and floodable counter-ballast tanks, allowing deepwater tooling baskets to sit stably on seabed templates before remote acoustically triggered buoyant recovery.
Every offshore basket undergoes multi-tier physical proof testing witnessed by independent classification societies (DNV, Bureau Veritas, ABS, or Lloyd's Register).
Subjected to static prototype proof loads of 2.5 × MGW across the four-point sling assembly, alongside an asymmetric 2-point lift test (at 1.5 × MGW) to verify torsional stiffness and pad eye shear resistance without permanent structural deflection.
In compliance with DNV 2.7-1 / EN 12079-3, units loaded to maximum payload are subjected to a free-fall drop test from a calibrated height onto an unyielding steel-faced concrete floor, validating base frame weld resilience against rough supply-boat deck impacts.
Each unit leaves our factory with a comprehensive Manufacturing Data Report (MDR), including full Mill Test Certificates (EN 10204 3.1/3.2), WPS/PQR records, NDT technician qualifications, coating thickness logs, and third-party signed survey certificates.
Optimizing your offshore basket fleet involves balancing initial capital expenditures (CapEx) against long-term maintenance, re-certification intervals, and operational availability.
By utilizing high-yield S355 fine-grain steels and finite-element structural profiling, CIMIC minimizes tare weight while maximizing certified payload capacity. Reducing basket tare by just 15% translates directly into decreased deck weight on supply vessels and lower fuel burn per transit.
Door hinges, locking mechanisms, slings, shackles, and lashing anchor points are engineered to standardized global industrial marine formats (Crosby, Green Pin, or equivalent certified forgings), ensuring rapid replacement anywhere from Aberdeen to Singapore and Macaé.
To combat elevated breakbulk ocean freight rates for extended length baskets (e.g., 40ft, 50ft, 70ft), our engineering team provides nested and stackable designs. Shorter baskets fit securely inside larger units, reducing total cubic shipping volume by up to 40%.
