The Pre-Dock Problem
Many shipowners enter dry dock without knowing the true condition of their vessel's steel structure. This uncertainty creates cascading operational and financial challenges that impact budgets, timelines, and negotiations with repair yards.
Unexpected Steel Renewal Scope
Hidden corrosion and structural degradation discovered during docking force sudden scope changes. What was planned as routine maintenance becomes major steel renewal, derailing project timelines and budgets.
Delays During Docking
Unplanned repairs extend docking duration, blocking the repair yard's schedule and delaying your vessel's return to service. Each day in dock represents lost revenue and operational disruption.
Increased Steel Repair Costs
Emergency repairs discovered during docking cost significantly more than planned work. Labor, materials, and expedited services inflate final bills well beyond initial estimates, straining capital budgets.
Difficult Shipyard Negotiations
Without independent data on steel condition, you negotiate from a position of weakness. Shipyards control the narrative, making repair scope and pricing decisions that favor their interests over yours.
The root cause: Lack of independent, technical assessment of your vessel's true steel condition before entering dry dock. Without this clarity, you face uncertainty, scope creep, and budget overruns.
Our Solution
NDTest provides independent steel condition inspections that let you understand your vessel's true structural condition before entering dry dock. Gain clarity, control, and the data you need to negotiate confidently with shipyards.
Plan Steel Repairs with Confidence
Our comprehensive UTM and visual inspections identify exactly which areas require renewal. You'll have precise scope definition before docking, eliminating guesswork and scope creep.
Reduce Unexpected Findings During Docking
Pre-dock inspections surface structural issues before you enter the yard. No more costly surprises mid-project. Our rope access and RIT capabilities reach areas others can't assess.
Prepare Accurate Repair Budgets
Detailed inspection reports include steel renewal estimates and weight calculations. You'll know your costs upfront and avoid budget overruns during docking.
Negotiate Using Independent Data
Our independent, third-party reports carry weight in shipyard negotiations. Class-society-accepted documentation supports your position and prevents unreasonable scope expansion.
