    Hull and Machinery Surveys at U.S. Ports

    Independent H&M damage surveys for underwriters and owners after grounding, contact, collision, machinery breakdown and heavy weather damage, with repair scope, cost review and repair supervision at Gulf Coast yards.

    What is a hull and machinery survey at U.S. ports?

    A hull and machinery survey is an independent inspection of damage to a vessel’s hull, propulsion, steering or machinery, usually for H&M underwriters or owners. Amica Marine surveyors establish cause, extent and fair repair cost, and monitor repairs where instructed. We do not issue class or statutory certificates.

    Amica Marine provides hull and machinery surveys at U.S. ports for H&M underwriters, average adjusters, shipowners and ship managers. Hull and machinery insurance covers physical loss of or damage to the vessel itself, so after a casualty the insurer needs an independent view of what was damaged, why, and what it reasonably costs to repair.

    Typical casualties include grounding and contact damage, main engine and auxiliary engine failures, turbocharger damage, shafting and stern tube problems, propeller and rudder damage, and heavy weather damage. On the Gulf Coast, shallow approaches, river shoaling and busy channels add groundings and contacts to the usual machinery casualties.

    The H&M surveyor works alongside, but separately from, the classification society surveyor. Class decides whether the vessel is fit to sail and what repairs are required for class; the H&M surveyor reports to underwriters on the cause of damage and the cost that falls under the policy.

    Amica Marine provides independent commercial and insurance surveys. Statutory and class surveys and certificates are issued only by the vessel’s flag state or classification society.

    When do underwriters and owners need an H&M surveyor?

    Underwriters and owners need an H&M surveyor after a grounding, contact, collision, machinery breakdown, fire or heavy weather damage, before repairs are agreed, during repairs to separate casualty work from owners’ work, and when repair invoices must be reviewed before payment.

    • Grounding on channel edges, river bars or approaches, with possible bottom plating, propeller or rudder damage.
    • Contact and allision with docks, buoys or other fixed objects.
    • Collision with another vessel, where the hull damage claim is separate from liability under P&I.
    • Main engine damage such as bearing failures, crankshaft damage, piston and liner failures or crankcase explosions.
    • Auxiliary machinery including generators, boilers, steering gear and cargo pumps.
    • Propeller and rudder damage from debris, ice or grounding.
    • Repair supervision where underwriters want a representative at the repair yard.

    Notifying underwriters and appointing a surveyor before repairs start protects the claim. Damage repaired before inspection may be difficult to recover under the policy.

    How does a hull and machinery damage survey work?

    The surveyor inspects the damaged parts, often with divers, class surveyors or engine makers, reviews logbooks, alarm records and maintenance history, establishes probable cause and extent, then reviews the repair specification and quotations to agree a fair cost for underwriters.

    A typical H&M investigation includes:

    • Inspection: visual inspection of hull damage alongside or in dry dock, underwater inspection reports by divers where the vessel is afloat, and opened-up machinery inspection.
    • Records: deck and engine logbooks, alarm printouts, lubricating oil analysis, maintenance and overhaul history, and running hours.
    • Specialist input: engine makers’ service engineers, metallurgists or naval architects where the cause is complex.
    • Cause: distinguishing a sudden casualty from wear and tear, latent defect or lack of maintenance, which affects policy cover.
    • Repair scope: agreement of necessary repairs with owners and class, and identification of owners’ work carried out at the same time.
    • Cost: comparison of yard quotations, labor and material rates, and allocation of common costs such as dry docking.

    The report is written for underwriters and average adjusters, who use it to adjust the claim under the policy terms.

    H&M surveys in Houston, New Orleans, Mobile and Gulf Coast repair yards

    Gulf Coast H&M casualties often involve groundings on channel edges and river bars, contacts in narrow channels, and machinery failures discovered during long anchorage waits. Repairs are carried out alongside, at anchorage or at repair yards and dry docks across the United States.

    Houston Ship Channel and Galveston Bay

    Channel edges, passing-ship interaction and dense traffic contribute to contact damage and groundings. Repair contractors in the Houston and Galveston area carry out afloat repairs, and topside and machinery work is often done alongside during cargo operations.

    Lower Mississippi River

    River shoaling, high-water currents and debris cause groundings, propeller and rudder damage. Vessels are often inspected by divers at anchorage or at buoys, with repairs at yards in the New Orleans area.

    Corpus Christi and the Sabine-Neches Waterway

    Tanker and bulk carrier traffic to export terminals and refineries brings machinery and contact casualties, sometimes discovered while the vessel waits at offshore anchorages.

    Mobile and the Alabama coast

    Mobile has shipyards and repair facilities serving commercial vessels. Damage surveys and repair supervision for casualties elsewhere in the Gulf may be carried out at these yards.

    Where repairs are planned at a Gulf Coast yard, we can attend from the opening-up of damaged equipment through to sea trials, reporting to underwriters at each stage.

    Hull and machinery survey packages compared

    Amica Marine offers three H&M survey scopes: an initial damage survey, a full damage and cost survey through repair planning, and repair supervision for underwriters. Each is quoted in writing after confirming the casualty, location, repair plan and the parties involved.

    How do I appoint an H&M surveyor after a casualty?

    Appoint an H&M surveyor by calling 404-390-2132 or emailing info@amicamarine.com with the vessel, IMO number, location, date and type of damage, and the instructing party. We confirm scope and quotation and attend before repairs start whenever possible.

    1. Notify the casualty. Call 404-390-2132 or email info@amicamarine.com with the vessel, IMO number, location, date and type of damage, and whether you represent underwriters, owners or another party.
    2. Confirm instructions. We confirm the scope, the parties to be notified, including class, and provide a quotation.
    3. Damage survey. The surveyor attends, inspects and photographs the damage, reviews logs and records, and discusses findings with the chief engineer, master and class surveyor.
    4. Repair scope and cost. The surveyor reviews the repair specification and quotations, separating casualty damage from wear and tear and owners’ work.
    5. Report and follow-up. A preliminary report follows the first attendance, with further reports through repairs and a final report on cost and cause.

    What does an H&M survey report include?

    An H&M survey report includes the casualty description and chronology, inspection findings and photographs, records reviewed, specialist findings, probable cause and its relation to policy terms, the agreed repair scope, cost assessment with allocation of owners’ work, and recommendations for further investigation.

    • Particulars of the vessel, policy and instructing party
    • Chronology of the casualty from logbooks and statements
    • Inspection findings with photographs and diver or maker reports
    • Probable cause and whether wear and tear or latent defect is involved
    • Repair scope agreed with owners and class
    • Cost assessment, quotation comparison and owners’ work allocation
    • Status of repairs and any outstanding items

    Information to send with your instruction

    Send the vessel name, IMO number, location, casualty date and description, class society, contact details for the superintendent and chief engineer, and any diver, class or maker reports already available.

    Why use an independent H&M surveyor for underwriters?

    An independent H&M surveyor gives underwriters a neutral assessment of cause and cost, separate from the owner’s superintendent and the repair yard. That assessment helps adjust the claim fairly, separates casualty damage from maintenance, and controls repair costs without delaying the vessel’s return to service.

    Owners want the vessel repaired quickly; yards want the work; underwriters want to pay for what the policy covers and nothing more. An independent surveyor balances these interests by recording facts and assessing costs objectively.

    For owners, an early H&M survey avoids disputes that delay payment. For underwriters and average adjusters, it provides a reliable basis for the adjustment. For both, a surveyor familiar with Gulf Coast repair practice helps keep repairs efficient.

    Amica Marine reports to the instructing party and coordinates with class without taking on the role of class.

    How is casualty damage separated from wear and tear?

    Casualty damage is separated from wear and tear by examining the physical evidence, maintenance and running-hour records, oil analysis, alarm logs and the sequence of events. Sudden fractures, impact marks and fresh deformation indicate a casualty, while gradual wear, corrosion and neglected maintenance indicate uninsured deterioration.

    The distinction matters because hull and machinery policies generally cover sudden and accidental damage, not the cost of replacing parts that have worn out or were poorly maintained. Most H&M disputes turn on this question.

    On machinery claims, the surveyor reviews overhaul intervals against the maker’s recommendations, lubricating oil analysis trends, alarm and shutdown histories, and the condition of components not directly involved in the failure. On hull claims, the surveyor compares the damaged area with surrounding structure for pre-existing corrosion, previous repairs and coating breakdown.

    Where the cause is uncertain, specialist input from engine makers, metallurgists or naval architects may be recommended. Our report explains which findings point to a casualty and which point to wear, so underwriters, average adjusters and owners can discuss the claim on the same factual basis.

    Hull and machinery survey questions from underwriters and owners

    These answers address common questions from H&M underwriters, average adjusters, shipowners and superintendents before appointing a hull and machinery surveyor at a U.S. port. For an active casualty, contact Amica Marine 24/7 at 404-390-2132.

    Is an H&M survey the same as a class survey?

    No. Class surveys determine whether a vessel meets class rules and can sail. H&M surveys assess cause, extent and cost of damage for insurance. Both may occur after the same casualty.

    Should repairs wait until the H&M surveyor attends?

    Yes, wherever safe and practical. Underwriters should inspect damage before repairs. If urgent repairs are needed, photograph everything, keep removed parts and notify underwriters and the surveyor immediately.

    Can you attend underwater damage inspections at anchorage?

    Yes, subject to access and weather. Divers perform the inspection; our surveyor reviews footage and findings, discusses them with class and the owner, and reports to underwriters.

    Do you assess main engine failures?

    Yes. We inspect opened-up engine components, review maintenance and oil analysis records, and work with engine makers’ engineers where needed to establish cause and the repair cost attributable to the casualty.

    Can you supervise repairs at a Gulf Coast shipyard?

    Yes. We attend repairs at berth or in dry dock to verify work performed, separate owners’ work and review invoices for underwriters until the vessel returns to service.
