Study Notes

Offshore Containers Diploma (OSC) Global Workbook

The OSC Diploma is a recognised industry-standard qualification for lifting equipment testers, inspectors, examiners, repairers, and maintainers.
The qualification is essential for anyone involved in the testing, inspection, and examination of offshore containers and assessing their suitability for continued service.
Key areas of training include: working on site, examiners' tools and equipment, offshore container standards, types of examination, terms, definitions, and symbols, design and construction, lifting eyes, lifting media, certification, lifting set design, container testing, lifting set testing, inspection report contents, pre-trip inspections, and safety precautions.
Learning outcomes include the knowledge to perform a thorough examination of offshore containers in service and validate fitness for service.
The course does not include ISO containers.
Students can use external resources to support analysis of lifting equipment suitability.

Working on-site

Professionals in the lifting equipment industry are expected to mitigate risk and keep people safe.
Stakeholders (customers and employers) expect high professional standards.
Competency in technical skills is necessary, but managing professional standards both internally and externally is equally important.
LEEA's Vision Statement emphasizes eliminating accidents, injuries, and fatalities in the lifting and height safety industries.

TEAM Card

The LEEA Diploma in Offshore Containers (Global) and the LEEA TEAM Card are awarded on successful completion of this training course and the end-point assessment.
A 'competent person' is defined by LEEA in its COPSULE, a standard of ability expected from TEAM Card holders.
Industry 'end-users' are encouraged to use LEEA member companies employing competent individuals.
Using LEEA TEAM Card holders ensures safety and minimizes risks for lifting equipment owners.

To ensure work permits and control measures are removed.
To ensure the customer can conduct operational checks on the equipment.

Equipment for Carrying Out On-Site Thorough Examinations

The offshore examiner will need a selection of hand tools, depending on the job nature (e.g., lifting equipment, scaffolding, cleaning equipment).
Suitable personal protective equipment (PPE) is necessary.
Measuring equipment calibration is required according to relevant standards.

Lighting

Adequate lighting (natural or artificial) is essential for defect identification.

Cleaning

Inspection areas must be reasonably clean and free from contaminants.

Cleaning Materials

Basic cleaning materials (rags, dustpan, brush, wire brush) and PH neutral cleaning fluids are recommended.
Follow data sheets and chemical warnings for product usage.

Offshore Container Standards

Various standards (e.g., BS EN 12079, BS 7072, DNVGL-ST-E271, BS EN ISO 10855) are referenced throughout for offshore container standards, inspection, and maintenance.
Standards guide national authorities in developing approval and certification requirements for offshore containers.

Withdrawn Standards for Offshore Containers

This section lists withdrawn standards for offshore containers, e.g., BS 7072:1989, BS EN 12079-1:2006, 2, and 3.

Current Standards for Offshore Containers

This section presents the current standards, e.g., DNVGL-ST-E271, BS EN ISO 10855-3, BS EN ISO 10855-1, and 2.

BS EN 12079-1: 2006

This European Standard outlines the design, manufacture, and marking requirements for offshore containers.

BS EN 12079-2: 2006

This European Standard outlines design, manufacture, and marking requirements for lifting sets.

BS EN 12079 - 3: 2006

This European Standard provides requirements for periodic lifting set inspection, examination, and testing.

DNVGL-ST-E271

This standard provides global certification for offshore containers.

ISO 10855-1, ISO 10855-2, and ISO 10855-3

This series of standards provides global certification for design, manufacture, marking, and periodic inspections / examinations for offshore containers.

Pad Eyes

Offshore containers typically use pad eyes at top corners for lifting set attachment.
ISO corner fittings are not suitable for offshore lifting.
Pad eye design is critical to resist lateral bending.
Clearance is controlled between pin and pad eye hole.

Shackles

Shackles employed in lifting sets must meet standards and safety criteria for their intended use, including the tolerance on pin diameter.

Coating and Corrosion Protection

Coating and suitable material are vital for offshore environmental conditions.

Tank Containers

These containers must comply with standards appropriate for dangerous goods, including structural considerations and fittings.

Impact Protection - Impact Protection on Tank Containers for Dangerous Cargoes

Tank components and fittings should be adequately protected from impact.
The tank top and its fittings should be protected by beams, plates, or grating.
Tank/fitting parts should not extend within 100mm of the top framework.
Tank areas nearest the tank shell must have protective beams.
Tank-bottom components below 150mm of the framework must have protection (beams or plating).

Lifting Set Markings

Individual lifting set components must have unique identification.
Lifting set slings must have permanently attached tags.

Certification

Any change to a container's design or manufacturing process requires new type testing of its mechanical properties.
Follow guidelines and use calibrated weights during any type testing.

Lifting Test

Container lifting should be done at a specific angle and be clear of the ground during testing.
No significant acceleration forces are allowed during the test.
5-minute hold is required before measurements.

All-Point Lifting Test

Containers are loaded to 2.5 x the maximum gross mass, and lifted using all pad eyes.
No deflections should exceed 1/300th of the span.

Two-Point Lifting Test

Load 1.5 x Maximum Gross Mass and lift using two diagonally positioned pad eyes.

Post-Lifting Test

Carry out non-destructive and visual inspection of pad eyes.

Vertical Impact Test

Lowering or dropping the container loaded with the desired mass onto a rigid surface with specific inclines and required distances from the floor/ground.

Other Tests

Open containers (6.5m+): Load to 1.6 x R + S and lift using fork pockets.
Tank containers for hazardous goods: Tested according to IMDG Code.

Inspection Report Requirements

Detailed inspection report requirements include container identification, owner information, report number, suitability statement, NDE details, marking confirmation, organization/individual details and dates & inspection scope.

Pre-Trip Inspections

Pre-trip inspections are essential for containers before transporting them offshore.
The inspection should verify the container's and lifting set's condition to ensure they are fit for use.
Check inspection plates, container damage, lifting set damage, correct connections, correct presence of parts, potential dropped items (with open container types), and secure doors and locking mechanisms.

Codes of Practice

International Maritime Organisation (IMO) is a specialized agency responsible for improving maritime safety and preventing marine pollution.
The IMO's International Maritime Dangerous Goods (IMDG) Code provides guidelines for handling/transporting dangerous goods and marine pollutants.

Terms and Definitions

An offshore container is a portable unit used for transporting goods/equipment between offshore installations and ships, with a maximum gross mass of 25,000kg.

Working Load Limits (WLL)

WLL is calculated based on the maximum gross mass of the container and an enhancement factor.
WLL values for different container types and lifting set configurations are provided.

Welding Requirements

Welding of primary and secondary structure members must be done using full penetration or fillet welds appropriate to the design parameters.

Materials

Containers are built from suitable materials able to withstand the offshore environment, including considerations for coating/corrosion protection.

Safety Precautions

Safety-related measures should be included in any procedures before starting work.
