4t Jumbo Piston Corer and lars

The project was developed from a basic concept for a seabed sediment core sampling tool. Griffiths Engineering Design Services developed the idea into an engineered solution, working with the client to ensure their expectations were met. The Project consisted of 2 principle elements, the Jumbo Piston Corer tool with variable sampler length and weight, and a LARS with a modular handling frame and 'A' frame lifting arm. The LARS was designed in accordance with DNV requirements for offshore lifting appliances, whilst the handling frame was analysised for environmental loading such as wave, current and vessel motion.

20T swl cpt spreader beam

4t Jumbo Piston Corer and lars

A client had a requirement for a suitable lifting device to interface with their existing LARS (Launch and Recovery System) and a new CPT (Cone Penetration Test) unit. The Lifting device was designed in accordance with DNVGL-ST-0378 and suitable for a subsea lift. The LARS winch location is dependant on the vessel of opportunity, therefore the spreader beam needed to accept a wide fleet angle. A detailed design package was delivered to the client enabling them to go straight to manufacture.

16-36" ILT

16-36" ILT

Development of a 16-36" Internal Lift Tool (ILT) for a marine contractor to enable handling of piles used in the marine/offshore construction industry. The tool is hydraulically actuated and grips the internal surface of the pile holding using saw toothed blocks. A modular design was developed to allow the tool to be adapted to a wide range of pile diameters and even for lifting casing with threaded ends. The detailed design, supporting calculations and engineering analysis report were submitted to the DNV for DVR review and approval.
