Vessel Damage Investigation & Marine Damage Survey
Independent technical investigation of vessel, structural, machinery, cargo and marine equipment damage, supported by physical inspection, technical evidence, photographic documentation and professional reporting.
Independent Vessel Damage Investigation
Vessel damage can result from collision, grounding, contact damage, heavy weather, machinery failure, cargo operations, mooring incidents, structural failure, fire, flooding or other operational events.
A properly conducted damage investigation is essential for establishing the actual condition of the vessel and documenting the technical circumstances surrounding the incident.
PAMS Pacific Admiralty Maritime Services conducts independent marine damage surveys and technical investigations from a marine engineering and surveying perspective. The assessment may consider physical condition, operational circumstances, available records, maintenance history, photographs, drawings, classification documentation and other relevant technical evidence.
Marine Damage Survey Scope
PAMS damage investigations may cover a wide range of vessel, machinery, cargo and marine equipment damage.
Hull & Structural Damage
Assessment of deformation, cracking, fracture, penetration, buckling, corrosion-related deterioration and other structural damage.
Collision & Contact Damage
Technical inspection following collision, allision or contact with berths, terminals, jetties, offshore structures, SPM systems, dolphins, fenders and other marine infrastructure.
Grounding Damage
