Welaptega to Present OTC Paper on In-Service Inspection of MODU Moorings

Welaptega Marine, world leader and exclusive supplier of in-water mooring inspection and subsea 3D in the offshore oil and gas industry, has been selected by the Offshore Technology Conference (OTC) Houston to present a paper on a pioneering technology for recertifying moorings on mobile drill rigs.

The paper, entitled In-Service Mooring Inspection for Mobile Drilling Units (MODU), will be presented during the technical program covering mooring integrity systems on Thursday afternoon.

The paper is a case study of a mooring inspection program on semi-submersible drill rigs while on station.

The technology was estimated to have saved the driller $10 million in maintenance costs on one rig alone.

His company worked with the client to develop the DNV-accredited technique for a top-side inspection program for moorings on MODUs.

“The technique has huge cost-saving implications for the entire moored semi-submersible sector because it eliminates the need for costly and time-consuming shore-based mooring inspections,” he said.

Welaptega conducted the inspection on-deck during a mooring recovery and relocation to another well. It completed the SPS-compliant inspection on each of eight mooring lines during two rig moves for the drilling company.

Welaptega deployed its patented chain measuring system (CMS) to conduct the inspection.

The Offshore Technology Conference is the world’s foremost event for the development of offshore resources in the fields of drilling, exploration, production and environment.
