Pre-Purchase Commercial Vessel Surveys

Purchasing a commercial vessel is both a marine transaction and a significant business investment.

A vessel that has accumulated substantial operating hours may have wear affecting propulsion machinery, generators, electrical systems, decks, structural components and commercial operating equipment.

A professional pre-purchase commercial vessel survey in San Diego provides an independent assessment before the buyer completes the transaction.

Depending upon accessibility and vessel configuration, the inspection may include:

• Hull and structural components

• Deck and superstructure

• Bulkheads and framing

• Main propulsion engines

• Transmissions

• Generator systems

• Fuel systems

• Steering systems

• AC and DC electrical systems

• Battery installations

• Shore-power equipment

• Plumbing and sanitation

• Bilge systems

• Navigation electronics

• Communications equipment

• Fire-protection systems

• Ground tackle

• Safety equipment

• Machinery spaces

• Passenger areas

• Commercial operating equipment

When practical, a comprehensive pre-purchase survey should also include an out-of-water inspection and operational sea trial.

Passenger & Charter Vessel Surveys

San Diego has a substantial passenger, charter, sportfishing and excursion-vessel market.

Passenger vessels require particular attention because vessel condition can directly affect crew, passengers and commercial operations.

Depending upon the type of vessel and agreed survey scope, inspection may include:

• Passenger deck condition

• Railings and guard structures

• Boarding areas

• Deck surfaces

• Machinery spaces

• Electrical installations

• Fire extinguishing equipment

• Life-saving equipment

• Bilge systems

• Navigation lights

• Fuel systems

• Emergency equipment

• Passenger accommodations

Regulatory requirements vary based on vessel size, passenger capacity, construction and type of commercial operation.

COI & U.S. Coast Guard Inspection Support

Certain passenger and commercial vessels operate under a U.S. Coast Guard Certificate of Inspection, commonly known as a COI.

Great River Marine Surveying can assist vessel owners and operators by conducting independent condition assessments and helping identify observable deficiencies before a Coast Guard inspection.

Areas reviewed may include vessel condition, machinery, electrical equipment, fire protection, lifesaving equipment, navigation equipment and other accessible systems within the agreed scope.

An independent marine survey does not replace an official U.S. Coast Guard inspection or certification. However, identifying deficiencies before presenting the vessel for inspection can help owners better prepare for the regulatory process.

Hull & Structural Inspection

Commercial vessels may be constructed of fiberglass, aluminum, steel, wood or composite materials.

Depending upon vessel construction and accessibility, inspection may address observable portions of:

• Hull plating or fiberglass laminate

• Frames and stringers

• Bulkheads

• Deck structure

• Transom

• Superstructure

• Engine beds

• Structural supports

• Watertight boundaries

• Keel

• Rudder

• Previous structural repairs

Conditions such as corrosion, cracking, moisture intrusion, deterioration, impact damage or previous repairs may be documented when observable.

Commercial Machinery & Propulsion Systems

Main propulsion machinery can represent one of the largest operating and replacement costs aboard a commercial vessel.

Depending upon survey scope and accessibility, inspection may include observable portions of:

• Main engines

• Engine mounts

• Transmissions

• Cooling systems

• Exhaust systems

• Fuel systems

• Shafting

• Propellers

• Steering equipment

• Engine controls

• Instrumentation

• Charging systems

• Generator equipment

Operational testing may be conducted when practical.

For more detailed internal engine diagnostics, specialized electronic testing or mechanical analysis, an independent engine technician may also be recommended.

Commercial Vessel Electrical Systems

Commercial vessels may contain more extensive electrical systems than smaller recreational craft, particularly when operating passenger equipment, commercial electronics, refrigeration, pumps or auxiliary machinery.

Inspection may include accessible portions of:

• Battery banks

• Battery switches

• AC and DC distribution panels

• Circuit protection

• Shore-power connections

• Battery chargers

• Inverters

• Generators

• Wiring

• Grounding and bonding systems

• Navigation lighting

• Electrical machinery

San Diego’s saltwater marine environment makes proper electrical installation, corrosion control and maintenance especially important.

Commercial Vessel Safety Equipment

Safety equipment can be a critical component of a commercial vessel inspection.

Depending upon vessel type and applicable requirements, the survey may review accessible:

• Personal flotation devices

• Life rings

• Fire extinguishers

• Fixed fire-suppression systems

• Emergency equipment

• Bilge pumps

• High-water alarms

• Navigation lights

• Signaling devices

• Ground tackle

• Communication equipment

• Emergency exits and access areas

Specific regulatory requirements depend upon how the vessel is operated and whether it is an inspected or uninspected commercial vessel.

Commercial Vessel Haul-Out Inspections

For many pre-purchase and condition surveys, an out-of-water inspection is strongly recommended.

Hauling a commercial vessel allows additional inspection of areas including:

• Underwater hull

• Propellers

• Shafts

• Struts

• Rudders

• Through-hulls

• Transducers

• Anodes

• Keel

• Underwater coatings

• Evidence of grounding or impact

San Diego has substantial marine repair and haul-out infrastructure capable of accommodating vessels ranging from smaller commercial craft to significantly larger yachts and working vessels.

Commercial Vessel Sea Trials

A sea trial allows the surveyor to observe machinery and vessel systems under actual operating conditions.

Depending upon the vessel and requested scope, observations may include:

• Main engine operation

• Engine temperatures

• Operating RPM

• Transmission operation

• Steering

• Controls

• Generator operation

• Navigation equipment

• Autopilot

• Vibration

• Maneuverability

• Bilge systems

• Other operational equipment

A sea trial complements the static inspection but does not replace specialized engine diagnostics.

Commercial Vessel Insurance & Condition Surveys

Insurance companies and lenders may require a current commercial marine survey before providing coverage or financing.

A Condition & Value survey can document the vessel’s observed condition, major machinery, installed equipment, safety systems and estimated fair market value when valuation is part of the assignment.

These surveys may be requested when:

• Purchasing a commercial vessel

• Obtaining new insurance coverage

• Renewing coverage

• Changing insurance carriers

• Refinancing a vessel

• Establishing vessel value

• Documenting major modifications or refits
