The exact scope of each assignment is determined by the nature of the casualty and the requirements of the client.
Boat Collision Damage Surveys
A collision can cause damage well beyond the immediately visible impact area.
Depending upon vessel construction and the location of impact, inspection may include observable portions of:
Hull laminate or plating
Deck structure
Stringers
Bulkheads
Transom
Hull-to-deck joint
Railings
Rubrails
Windows
Interior structural areas
Machinery
Steering equipment
Underwater components
Photographs and written observations can document visible damage present at the time of inspection.
If destructive testing, engineering analysis or specialized mechanical evaluation is required, additional specialists may be recommended.
Grounding & Underwater Damage Surveys
Grounding incidents can affect underwater components that cannot be properly evaluated while the vessel remains afloat.
Depending upon vessel type, inspection may address:
Underwater hull
Keel
Propellers
Propeller shafts
Struts
Rudders
Sterndrives
Outboard lower units
Trim tabs
Through-hulls
Transducers
Structural areas near the impact
An out-of-water inspection is often recommended when grounding or underwater impact damage is suspected.
San Diego has extensive boatyard and haul-out infrastructure, allowing damage inspections to be coordinated while the vessel is ashore.
Water Intrusion & Flooding Damage
Water intrusion can affect machinery, electrical systems, structural materials and interior components.
A damage survey may document observable condition of:
Engines
Generators
Batteries
Electrical panels
Wiring
Navigation electronics
Pumps
Interior accommodations
Cabinetry
Flooring
Structural components
Fuel systems
Plumbing systems
The extent of damage may depend upon how high the water reached, the duration of exposure and whether the water was fresh, brackish or saltwater.
Prompt inspection can be especially important because corrosion and electrical deterioration may continue after the initial casualty.
Fire & Electrical Damage Surveys
Marine fires and electrical incidents may affect areas beyond the apparent origin of the event.
Observable damage may include:
Burned or heat-affected materials
Wiring
Electrical panels
Batteries
Shore-power systems
Machinery spaces
Interior finishes
Structural components
Nearby equipment
Smoke damage
Heat damage
Determining the precise origin or cause of a fire may require a specialized fire investigator or electrical expert.
A marine damage survey can independently document the observable damage and overall vessel condition following the incident.
Machinery & Propulsion Damage
Some marine casualties primarily involve engines, propulsion systems or related machinery.
Depending upon the assignment, inspection may involve observable:
Main engines
Transmissions
Outboards
Sterndrives
Propeller shafts
Propellers
Engine mounts
Exhaust systems
Cooling systems
Fuel systems
Steering systems
Associated machinery
Specialized internal engine evaluation, computerized diagnostics or teardown inspection may require a qualified engine technician.
The marine surveyor can document the broader casualty and incorporate specialist findings when those services are part of the assignment.
Damage Surveys for Insurance Claims
Insurance carriers and claims professionals may require independent documentation following a reported loss.
Depending upon assignment instructions, a marine damage survey report may include:
Vessel identification
Date and location of inspection
Description of the reported incident
Observable damage
Photographic documentation
Areas affected
Available supporting records
Repair considerations
Recommendations for further inspection
Other relevant observations
Great River Marine Surveying's San Diego service area already includes Damage & Insurance Claim Surveys as part of its local marine survey services.
Yacht Damage Surveys
San Diego supports a substantial yacht and large-vessel market, and damage to a larger yacht can involve multiple structural, mechanical and electrical systems.
A yacht damage assignment may involve:
Hull and superstructure damage
Machinery
Generators
Electrical systems
Hydraulic equipment
Thrusters
Navigation electronics
Interior accommodations
Tender equipment
Docking damage
Underwater running gear
Because yacht systems can be complex, additional technicians or specialists may be appropriate for certain assignments.
Transportation & Boatyard Damage
Damage may also occur while a vessel is being transported, hauled, launched, stored or serviced.
Assignments may involve:
Trailer transportation damage
Over-road yacht transport
Forklift damage
Travel-lift incidents
Blocking or storage damage
Launching accidents
Haul-out damage
Boatyard incidents
Dropped or shifted equipment
A prompt inspection can help establish a photographic record before repairs or additional handling takes place.
Repair Documentation & Follow-Up Inspections
Some marine damage assignments require more than one attendance.
Follow-up inspections may document:
Components removed for inspection
Concealed damage discovered during repairs
Repair progress
Additional casualty-related damage
Replacement components
Structural repairs
Completed repair work
Photographic records
The scope of additional inspections should be established with the owner, insurance company, adjuster, attorney or other requesting party.
Independent Marine Damage Documentation
A professional damage survey is intended to provide independent documentation of observable conditions.
Not every deficiency discovered during an inspection is necessarily related to the reported casualty.
Some conditions may have existed before the incident, while others may require additional investigation before their relationship to the loss can be determined.
Maintaining this distinction provides vessel owners, insurers and attorneys with clearer professional documentation.
San Diego Saltwater Damage Considerations
San Diego vessels operate in a year-round saltwater environment.
Following a casualty, saltwater exposure can accelerate deterioration of:
Electrical connections
Wiring
Batteries
Engines
Generators
Navigation electronics
Underwater metals
Pumps
Mechanical components
Prompt mitigation and proper preservation may be particularly important following flooding, partial submersion or heavy water intrusion.
