Ship-to-Shore (STS) Crane Inspection & Certification in Jubail
A ship-to-shore crane is a rail-mounted quay gantry with a hinged boom and a trolley that carries a container spreader between the vessel and the apron. They work the container berths at Saudi ports such as Dammam, Jeddah and King Abdullah Port, where salt-laden air, sand and constant duty cycles drive corrosion and wire rope wear. An independent examination gives terminal operators and insurers evidence that the structure, hoisting machinery and protective devices are still fit for continued service. Jubail Industrial City hosts the world's largest petrochemical complexes, requiring rigorous lifting and heavy-equipment compliance.
Ship-to-Shore (STS) Crane inspection in Jubail: local context
Cargo for Jubail Industrial City's plants, from project equipment to containerised industrial products, typically passes through its ports, so port lifting equipment such as ship-to-shore cranes, gantries, straddle carriers and marine lifting appliances works in salt spray with little room for downtime. Corrosion on wire rope, slew rings and spreaders is a constant concern. EES inspects and load tests port and marine lifting equipment, arranging work around vessel schedules and berth operations.
Ship-to-Shore (STS) Crane inspection scope in Jubail
- ✓Boom girders, boom hinge pins and boom latch inspected for fatigue cracks, corrosion and pin or bush wear, with particular attention to the waterside boom hinge and backreach connections
- ✓Main hoist, trolley and boom hoist wire ropes measured for diameter reduction, broken wires, corrosion and rope lay distortion, with sheaves and rope drums checked for groove wear
- ✓Trolley rails, trolley wheels, trolley drive and trolley anti-collision stops checked for wear, misalignment and secure end buffers
- ✓Spreader twist locks, flipper guides, telescoping drive and landing pin sensors tested for correct locked and unlocked indication and for wear on lock cones
- ✓Gantry rail wheels, equalising bogies, buffers and rail clamps or storm tie-downs checked for wear and positive engagement before high-wind conditions
- ✓Anemometer, wind speed alarms, boom hoist limit switches, overspeed protection and overload cut-outs functionally tested
- ✓Hoist, trolley and gantry brakes tested for torque and holding ability, with brake pads and discs measured for wear
- ✓Operator cab, emergency stops, communications, access ladders, handrails, fire protection and festoon or cable reel systems checked for condition and function
Defects commonly found
- ✓Cracks developing at boom pin lugs or weld toes in the boom and portal frame
- ✓Broken wires and core protrusion on hoist ropes near the spreader end and over the rope sheaves
- ✓Worn or damaged spreader twist locks that give false locked indication
- ✓Corroded or seized rail clamps and storm anchors that do not fully engage
- ✓Faulty wind speed alarms or limit switches that are bypassed or out of adjustment
Standards
- ✓ISO 9927-1 (cranes, inspections, general)
- ✓ISO 4309 (wire ropes, examination and discard criteria)
- ✓ISO 12480-1 (cranes, safe use, general)
- ✓ASME B30.20 (below-the-hook lifting devices)
Testing
A rated load test is typically carried out with certified test weights or a calibrated test container at 100% to 125% of rated capacity depending on the standard and client, covering hoisting, trolley travel, boom positioning, braking and the overload protection settings. The test also confirms spreader functions and limit switch operation with the crane under load.
Frequency
Typically at least annually for a full thorough examination, with pre-mobilisation checks, post-incident inspection and more frequent rope and spreader checks where terminal or insurer rules require.

FAQs
Can you inspect a ship-to-shore (STS) crane on site in Jubail?＋
Yes. Our inspectors travel to your yard or project site in Jubail, including Jubail Industrial City, Jubail Commercial Port and SABIC plants, so the equipment does not need to be moved.
Which industries in Jubail request ship-to-shore (STS) crane inspection?＋
Typically operators and contractors in the Eastern Province from these sectors: Oil, Gas & Petrochemical; Ports, Logistics & Warehousing.
How often should a ship-to-shore crane be inspected by a third party?＋
A full thorough examination is typically done at least once a year, and again after major repairs, boom modifications or a significant incident. Terminal operators often add more frequent wire rope and spreader inspections because of heavy duty cycles in coastal conditions.
Does an STS crane need a load test as well as a visual inspection?＋
A visual inspection finds wear and cracking, but only a load test proves the brakes, hoists and overload devices hold at rated capacity. Most terminals ask for a load test after commissioning, after major structural or machinery work and at the interval set by their procedure.
