Flat Glass Stowage, Loading & Discharging Survey

Transporting float, sheet, laminated, and processed glass by sea demands continuous technical oversight from the initial port loading phase through to final discharge. Due to high fragility, vulnerability to dynamic vessel roll, and sensitivity to moisture-induced staining, MP Inspection provides end-to-end 3rd-party flat glass stowage engineering, loading supervision, outturn discharging audits, and damage assessment for glass manufacturers, logistics providers, shipowners, and marine insurers worldwide.

Key Services & Operational Scope

1. Pre-Load Engineering & Custom Stowage Planning

Evaluation of glass packaging formats, including wooden crates, steel A-frames, stillages, end-caps, and glass block bundles.
Creation of custom hold and deck stowage schemes aligned with vessel trim, GM stability figures, and deck point-load limits ( $t/m^2$ ).
Orientation planning to ensure glass crates are positioned parallel to the vessel’s centerline, mitigating transverse roll acceleration forces during transit.
Inspection of high-density rubber/wooden dunnage, load-spreading beams, and anti-slip friction mats.

2. Quay & Loading Port Supervision

24/7 on-site monitoring of stevedore handling, crane operations, and forklift maneuvers at quay and inside cargo holds.
Enforcement of specialized lifting gear usage (spreader bars, vacuum lifting frames, and soft web slings) to eliminate sudden shocks or severe tilt angles.
Verification of hold cleanliness, water-tightness, and desiccant placement to prevent moisture accumulation between glass sheets (glass sweating/staining).

3. Discharging Supervision & Outturn Audits

Pre-discharging hatch opening audits and verification of seal integrity prior to commencing discharge.
Continuous supervision of unlashing, A-frame removal, and quay-side transfer at the destination port.
Complete outturn survey reporting to verify landed quantities against Bills of Lading and identify handling defects immediately upon discharge.

4. Breakage & Damage Root-Cause Investigation

Detailed physical examination of chipped, cracked, or shattered glass crates during or post-operation.
Technical identification of primary damage causes: mechanical impact, improper lashing tension, structural flex of hold floors, or packaging failure.
Chemical silver nitrate testing to differentiate between sea-water ingress and atmospheric freshwater condensation.

International Standards & Compliance

Our flat glass survey operations strictly follow global maritime safety codes and manufacturing guidelines:

IMO CSS Code (Code of Safe Practice for Cargo Stowage and Securing)
IMO/ILO/UNECE CTU Code (Code of Practice for Packing of Cargo Transport Units)
ISO 9050 / EN 572 (Glass in Building — Basic Soda Lime Silicate Glass Products)
