Expertise

Technical services shaped around the decision at hand.

From a focused machinery failure to a complex refit dispute, each engagement begins with a defined technical question, an appropriate inspection scope and a clear understanding of who will rely on the conclusions.

Independent work built for scrutiny.

Grubb Marine Surveying & Consulting accepts assignments from yacht owners, attorneys, insurers, financial institutions and other marine-industry stakeholders. The work is proportionate to the matter: focused where the question is narrow, comprehensive where the consequences demand it.

Refit & Project Consulting

Independent technical involvement before, during or after a refit. The work may range from specification and contract review to progress verification, quality control, deficiency assessment and the development of a practical remedial scope.

  • Shipyard and contractor evaluation
  • Specification, proposal and change-order review
  • Progress, workmanship and payment verification
  • Structural, mechanical, electrical and coating quality control

  • Flooding and partial-sinking events
  • Machinery and component failures
  • Structural and composite damage
  • Corrosion, maintenance and installation analysis

Expert Witness & Dispute Support

Technical support structured for the demands of insurance claims, mediation, arbitration and litigation. Reports are written to be understood by non-engineers while preserving the engineering basis for each opinion.

  • Independent inspection and testing strategy
  • Failure analysis and expert reporting
  • Counsel support, deposition and testimony

Reasoned market-value and replacement-cost opinions supported by vessel condition, specifications, documented improvements, current market evidence and the purpose of the appraisal.
