ROV A-Frame and Winch System
Structural Analysis of Cable Lay Vessel
Murcott Energy was consulted by a Cable Lay Vessel OEM to provide a structural assessment of their A-Frame and Winch system.
Overview
Murcott Energy was consulted by a Cable Lay Vessel OEM to provide a structural assessment of their A-Frame and Winch system.
The customer also required Murcott Energy to provide classification society liaison with Lloyd’s Register, and to achieve Design Appraisal Documentation.
Application
The A-Frame and Winch were required to lower and lift a Remote Operating Vehicle (ROV) from the vessel to the sea floor in conditions up to and including Sea State 4. The analysis required to account for all dynamic loads and the heel and trim of the vessel.
Analysis Objectives
Simulate in-board and out-board conditions with reference to Lloyd’s Register, ‘Code for Lifting in a Marine Environment’.
Provide design optimisation guidance to the customer, addressing issues and improving design efficiency and cost effectiveness.
Provide interface loads to the wider deck structure, for use by the client’s Naval Architect.
Develop a finite element analysis (FEA) model from precise 3D CAD data.

Capabilities Employed
Murcott Energy utilized advanced engineering techniques, including:
Load Simulation
Safety Assurance
Material Validation
Results and
Benefits
The initial results identified some areas that required modification. Murcott Energy was able to work swiftly with the client to identify viable solutions. Once the design was fully validated for structural integrity, the technical reporting pack was submitted to Lloyd’s Register for review.
The design and supporting documentation subsequently achieved the Design Approval Documentation from Lloyd’s Register, enabling the customer to proceed to manufacture ahead of urgent cable lay campaigns for the vessel.
