Steel structure is the backbone of any marine vessel, offshore unit or industrial facility. The severe marine environment continuously subjects these assets to very severe conditions, they are subjected to the ever-changing seawater, heavy load of operations, and extreme change of temperature, which inexorably results in the wear, corrosion, cracking, and deformation of these assets. The Services of High-quality Steel Work / Steel Repair Work are thus basic to the structural integrity and operational safety. Sun Marine Engineering offers end-to-end certified steel fabrication, which is used in vessels and restoration to repair solutions, in order to protect your assets against early failure.
What are steelwork / Steel repair work services?
Steel Work / Steel Repair Work Services are all inclusive of the activities that concern maintenance, alteration and repair of metal objects.
- Definition: The services in question include cutting, shaping, welding and fabrication services, which are performed with precision, as well as reinforcement and the final replacement of steel elements.
- Scope: It can be either a complex structural steel work or any small work on replacing the steel plate, which aims at restoring the structure back to its original design specification or even more.
- Compliance: Professional steel repairs will guarantee the safety of the vessel, structural integrity, as well as compliance with classification society rules.
The Reason Why Steel Work and Steel Repair Are Necessary in Marine and Offshore Workplaces
The special marine environment under which the marine sector operates necessitates professional steel repair.
- High Corrosion Rates: This is because continuous exposure to seawater and humid air promotes corrosion and periodic hull steel renewal and plate replacement is required.
- Heavy Loads and Stress: Offshore platforms and working vessels experience predominant cyclical stress, and the ship’s steel structure needs to be reinforced frequently to avoid fatigue cracking.
- Wear and Tear: Localised wear is brought about by operational wear, anchor chain abrasion and heavy cargo movements.
- Regulatory Requirements: Repairs to the steel, which have been found to be approved by the Classification societies, are obligatory; the classification societies provide minimum plate thickness and structural requirements that must be complied with.
- Safety-Critical Performance: The integrity of the structural components is the main protection against the sinking or the platform’s collapse and therefore, its integrity is a safety-critical question.
Applications of Steel Work / Repair Work.
We offer services on external and internal structures of the marine assets.
- Hull and Structural Repairs: This is the renewal of plates, beams, frames and stiffeners that have corroded or been hit.
- Tank & Compartment Repairs: Tank repair involves repairing the steel integrity of the ballast tanks, cargo tanks or fuel tanks to prevent leakages and maintain water tightness.
- Deck and Superstructure Steel Work Repairing deck plating, strengthening equipment foundations and making accessories such as walkways, ladders and handrails.
- Pipe Racks and Structural Supports: Pipe rack fabrication and structural supports. Engine rooms and pump rooms often have high vibrations that may result in structural fatigue.
- Offshore Platform Steel Repairs: Structural support of skid frames, modules, jacket structures and living quarters, and provided by specialised offshore steel repair teams.
Steel Work that Sun Marine Engineering deals with
- Service Fabrication Steel: Custom heavy steel fabrication, this type of fabrication is the correct cutting, welding, bending and rolling of parts of steel which are to be used in new installations.
- Structural Steel Repair and Reinforcement: It is a procedure of recycling and repair of damaged or corroded structural parts to resume the load-bearing capacity.
- Steel Modification Works: Steel modification works to be performed to retrofit new equipment, install foundations, or carry out varying tasks on vessels.
- Emergency Steel Repair Services: Instant and urgent repair services onboard and at the quayside, which can be carried out by rapid response teams.
- Shipyard & Offshore Steel Work: Onboard steel work services that are executed in the shipyards or mobilised to remote areas that are very far from the sea.
Steel Repair Process (Step-by-Step)
Our repair process is strict to make sure that all repairs are safe and certified.
- Primary Inspection and Evaluation: Figuring out the extent of damage, cause of defect and repair needs (which may include a marine structural repair solutions expert).
- Measurement & Cutting Plan: Complex calculations of the measurement of the current structure and elaboration of the cutting/welding plan.
- Designing of New Components: This is the fabrication of new steel plate replacement or components in the workshop, where they were cut and assembled in advance to execute onboard.
- Repair Implementation: The damaged parts are removed, and the new components of steel are fitted in their place of repair.
- Welding & Finishing Welding, grinding and finishing completed to standard requirements.
- Quality Checks, NDT Testing: The Non-Destructive Testing (NDT) to be performed to assure the integrity of the weld includes Ultrasonic Testing (UT), Magnetic Particle Inspection (MPI) and Dye Penetrant Inspection (DPI).
- Class Acceptance: Final approval of the inspector of the necessary classification society.
- Last Inspection and handover: Coating of the protection and finalization reporting.
Professional Opportunities in Steel Work and Repair
- Ensures Safety and Structural Stability: This is the fundamental advantage of structural integrity to operational forces.
- Extends the Life of Vessels: Preventive maintenance and replacement of steel plates will ensure that a small accident does not affect the whole structure.
- Avoids Disastrous Failures: It will help prevent disastrous failures that could cause considerable downtime and environmental problems.
- Meets Compliance: Ensured that all the classification and regulatory standards have been met.
- Precision Fabrication: Shop and field fabrication will be of high precision and will provide high-accuracy fitting and high durability.
