New subsea inspection service for offshore

Lloyd’s Register (LR) has released its Subsea Inspection Services to support underwater inspections of subsea pipelines, assets and facilities for energy companies operating offshore, a press release stated. Services include project management, consultancy, personnel, quality control, data processing and data management applicable to ROV, AUV and diver projects. Headed by LR’s Subsea Inspection Manager Andrew Inglis and delivered by the company’s in-house experts in subsea inspection, survey and asset integrity, services will be provided to operators and contractors in the offshore oil and gas, wind farm, and submarine cable sectors. As operators begin to prepare for their annual subsea inspection programs, the company’s expertise will help operators achieve their subsea asset integrity requirements by optimizing project planning, execution and delivery and facilitating the potential for multiclient multiproject operations.

Collaboration lights the way for improved diver safety

A new on-demand wireless ribbon lighting system designed to improve diver safety and efficiency in remote subsea locations has been released following a collaboration between WFS Technologies Ltd. and PhotoSynergy Ltd. (PSL), a press release stated. Seatooth LIGHTPATH is a combination of two advanced technologies—WFS’s Seatooth, a subsea wireless communication system that can download and log information gathered on subsea installations remotely, and PhotoSynergy Ltd.’s LIGHTPATH, a side-emitting flexible fiber that projects a continuous line of light that carries no electrical power. The new product works for both diver and ROV operators working either near surface or at depths of up to 3,000 m (9,842.5 ft). The light is engaged automatically when the diver or the ROV comes within 5 m (16 ft) of a structure and provides instant illumination of subsea architecture and delineating features such as control valves, docking bays and even the outline of the structure itself against the natural darkness of the underwater environment. It switches off automatically when the diver or the ROV departs the scene and has the ability to act as a proximity warning system when approaching installations, other divers, ROVs or danger areas. The unit has been successfully tested in a laboratory and was scheduled to be trialed in subsea conditions in early 2017.

Air-mobile capping stack for global subsea market

Boots & Coots Services, a Halliburton business, has developed the Global Rapid Intervention Package (GRIP), a suite of services designed to help reduce costs and deployment time in the event of subsea well control events, a press release stated. GRIP provides well planning and well kill capabilities facilitated by the company’s global logistics infrastructure and existing product service lines. This includes an inventory of well test packages, coiled tubing units and relief well ranging tools. In addition, GRIP features the new high-temperature 15,000-psi RapidCap air-mobile capping stack. Sourced from Trendsetter Engineering Inc., RapidCap incorporates a specially designed gate valve-based system, making it significantly lighter, less expensive and more mobile than options currently on the market, according to the company.

Reimaging program improves data quality

TGS-NOPEC Geophysical Co. (TGS) and Schlumberger announced a new multi- and wide-azimuth (M-WAZ) multiclient reimaging program in the highly prospective Central U.S. Gulf of Mexico, a press release stated. Final results are expected in early 2018, ahead of a period when substantial block turnover in the area is anticipated. The new Fusion M-WAZ reimaging program comprises data covering more than 1,000 Outer Continental Shelf blocks (about 23,000 sq km or 8,880 sq miles) from 3-D WAZ programs previously acquired by TGS and Schlumberger with the WesternGeco Q-Marine pointreceiver marine seismic system between 2008 and 2012. This large reimaging program will process data from the Mississippi Canyon, Atwater Valley and Ewing Bank areas using the latest imaging technology to provide a significant uplift in data quality for upcoming licensing rounds. The area is expected to remain a high priority for E&P companies in the foreseeable future and will benefit from two licensing rounds every year for the next five years under the new Bureau of Ocean Energy Management 2017-2022 five-year program.

New subsea sampling cylinder reduces risks

Proserv has released a new subsea sampling cylinder that is designed to improve the quality of results and reduce risks normally associated with sample transfer, a press release stated. Based on existing technology, the Proserv Subsea Sampling Cylinder (SSC) is the world’s first fully qualified and certified “for shipping” sample cylinder to be deployed in a subsea environment. The system accurately captures well properties throughout the lifetime of a field. Subsea cylinders allow operators to take representative production samples from a subsea system for direct transfer to a laboratory. Proserv’s SSC eliminates the risks associated with handling and transferring samples on the surface, reducing the risk of containment loss and exposure to H2S/CO2.

Understand the growth, size and scope of subsea opportunities

Douglas-Westwood has released its Subsea Cable Tracker, which identifies the vessel installation day demand and a breakdown of component type by region as well as considering global drivers and outlook, a press release stated. Over the next five years Douglas-Westwood expects to see a significant increase in subsea cable demand, primarily driven by the strong growth in the offshore wind market. Douglas-Westwood has released the Subsea Cable Tracker to assist businesses in understanding this growth and the size and scope of opportunities that exist. The tracker details the subsea cable demand growth totaling 24,103 km (14,978 miles) over the 2017-2021 forecast period.
