Lashing & Cargo Securing Approval Survey Services

Preventing cargo movement, sliding, or tipping during sea transit is critical to preserving vessel stability, protecting high-value freight, and ensuring maritime crew safety. MP Inspection provides independent 3rd-party lashing inspections, cargo securing calculations, and formal securing approval certification for shipowners, charterers, freight forwarders, and marine warranty underwriters worldwide.

Key Services & Operational Scope

1. Pre-Lashing Calculations & Securing Plan Audits

• Technical review of the vessel’s Cargo Securing Manual (CSM) against cargo weight, dimensions, and center of gravity.
• Calculation of acceleration forces (transverse, longitudinal, and vertical), friction factors, tipping moments, and sliding risks based on route weather projections.
• Certification verification of lashing gear, including D-rings, pad eyes, lashing chains, wire ropes, turnbuckles, and web lashings.

2. On-Site Securing Oversight & Welding Inspection

• On-deck and hold inspection of stoppers, shoes, and clip welding to vessel structural members (frames, tank tops, coamings).
• Verification of dunnage distribution, rubber anti-slip mats, and load-spreading wooden cradles under heavy contact points.
• Inspection of lashing angles, symmetry, and tensioning devices to guarantee uniform load distribution.

3. IMO CSS Code Annex 13 Advanced Securing Audits

• Specialized calculations for non-standardized cargo, heavy lift machinery, wind turbine components, and oversized industrial units.
• Evaluation of securing arrangements under extreme sea state conditions and high-metacentric-height (GM) roll forces.
• Guidance on dynamic lashing adjustments prior to ocean towage or winter voyages.

4. Certification & Port Departure Clearance

• Continuous monitoring of lashing application up to the point of vessel unberthing.
• Issuance of official Lashing & Cargo Securing Approval Certificates required by Port State Control (PSC), Coast Guard, and P&I Clubs.
• Complete photographic evidence logging and technical statements of compliance.
