Anchor and Chain Services — Technical Specification

Scope of Services

Seachios® delivers inspection, repair, refurbishment, and replacement of anchors and chains to ensure operational reliability and compliance. Services are performed in accordance with IACS-class standards (BV, DNV, LR, NKK) and Brazilian port authority requirements.

Inspection

Dimensional checks: measurement of link length, diameter, and wear against class tolerances.
Nondestructive testing (NDT): magnetic particle, ultrasonic, and dye penetrant inspection to detect cracks, fatigue, and corrosion.
Visual examination: assessment of coating, deformation, and structural integrity.

Repair and Refurbishment

Welding and grinding: executed with approved procedures and metallurgical compatibility.
Link straightening and reshaping: restoring geometry within tolerance.
Corrosion treatment: removal of scale and application of protective coatings.
Hardfacing: applied to extend service life in high-wear zones.

Replacement

Supply and fitting of certified anchors (stockless, Delta, Bruce) and stud-link chains.
Traceability of material grade, forging standards, and certificates provided for class endorsement.
Associated hardware replacement: shackles, swivels, joining links.

Engineering and Adaptation

Evaluation of holding capacity and load distribution for vessel class and displacement.
Adaptation of anchoring systems to seabed conditions (sandy, muddy, rocky).
Documentation for class submission and port authority approval.

Technical Parameters

Service Type	Focus Area
Inspection	Dimensional checks, NDT methods, wear and crack detection
Repair & Refurbishment	Welding procedures, grinding, corrosion removal, hardfacing
