Seismic Support Overview
Through the distillation of years of experience, ongoing product development, and the retention of key personnel with superior expertise, NCS SubSea (NCS) remains at the forefront of marine seismic support with an emphasis on navigation, positioning and seismic source services for offshore operations. NCS offers customizable hardware and software configurations and post-processing workflows founded on the following key functionalities:
- Comprehensive shore-based support for companies without internal navigation equipment
- Proprietary or industry-standard integrated navigation systems
- Online positioning for all vessels and in-water seismic equipment
- Real-time coverage monitoring and binning
- Offline post-processing of navigation data
Seismic Support Offshore Team
At NCS SubSea, members of the offshore team are our greatest asset. Nearly every crew member on nearly every job is a full-time NCS employee. NCS takes pride in retaining excellent talent throughout industry ups and downs, our collective experience and teamwork are our differentiators.
Ocean Bottom Seismic
NCS SubSea supports the full suite of navigation tasks involved in conducting an OBS survey including source vessel control and positioning, node deployment and recovery, and USBL acoustic positioning of seafloor nodes with acoustic transponders. Depending on customer needs, NCS is capable of supporting seismic operations through the provision of equipment and/or personnel all the way up to complete onshore or offshore support, essentially acting as our customer’s navigation department.
VSP and DAS
NCS SubSea provides complete source vessel support, up to and including the provision of a fully-rigged and manned seismic source vessel for offshore downhole seismic data acquisition. For either VSP (vertical seismic profile) or DAS (distributed acoustic sensing) application, NCS offers a complete package including source array design and operation; real-time navigation and positioning; timing and event control; and near field hydrophone recording and QC.
NCS SubSea uses industry-standard or proprietary navigation and positioning systems to support both conventional 2D and 3D streamer data acquisition and ultrahigh resolution 3D systems such as P-Cable. Additionally, NCS supports the provision of remote source vessels for wide azimuth, rich azimuth and ultra-long offset streamer surveys.
From Project Manager and Party Chief level to system-specific operators, NCS SubSea offshore crews and onshore support teams are eminently capable of providing full project management services from planning and inception to completion and close out. Our integrated project management approach, based on the industry-standard PDCA (Plan-Do-Check-Act) model, ensures that each project we undertake is on time and on budget.
