UTEC Completes ROV Nav,
Seismic Project in Gulf

UTEC Survey has successfully completed a significant ROV navigation and seismic node positioning project in the deepwater Gulf of Mexico for FairfieldNodal in 2,425 m depth using acoustics and inertial positioning technology. A key element was the creation of an improved navigation software package incorporating the latest NavView technology from 4D Nav. The system provided enhanced and precise positioning awareness along with the management of inertial sensors and a bespoke link to FairfieldNodal’s data acquisition system.

Protea Delivers Chain
Hoist for VLS

Protea has adapted chain hoist technology for an offshore pipelay application with the delivery of a chain hoist to be installed on a vertical lay system (VLS). The 20-mT SWL chain hoist system was delivered to Remacut in Italy for installation on a 150-mT capacity VLS, which will be used to lay various offshore products (including flexible pipeline, umbilical and power cables) ranging 50 mm to 600 mm in diameter.

The chain hoist will be used for general handling operations in the worktable area and features a lifting height of 5 m and max hoist travel speed of 2.5 m/min. It is fully compliant with the DNV 2.22 Lifting Appliances standard.

IOGP Releases Technical
Notes on Offshore Drilling

A properly conducted drilling hazard site survey for an offshore drilling location is essential to minimize the risk of harm to personnel and equipment and to protect the natural environment. In 2013, the International Association of Oil & Gas Producers (IOGP) published guidelines for the conduct of offshore drilling hazard site surveys. IOGP’s new technical notes publication provides extensive supporting technical information to those guidelines. This includes background theory on the various phases in delivery of a site survey project, on the vessels and equipment used to acquire site survey data, and on the data processing and interpretation techniques. The techniques may also be applied to other types of seabed surveys for platform sites and pipeline and cable routes.

The guidelines and technical notes can be downloaded free at www.iogp.org/library.

Fugro to Start Geotechnical
Investigations off India

Fugro is to commence a major program of offshore geotechnical investigations under a contract awarded by Indian oil and gas company, ONGC. The contract involves site investigation work to gather geotechnical and geohazard data at the field, which is located in the KG-DWN-98/2 block off the east coast of India. The information will support the design and subsequent installation of wellheads, manifolds, platforms, FPSO anchors, umbilicals, pipelines and flow lines.

Fugro’s deepwater geotechnical vessel will perform the work in water depths ranging from 50 to 1,500 m. The fieldwork will be followed by extensive laboratory testing, data analysis, interpretation and integration with other data acquired by Fugro.

Lease Sale 248 to Offer
23.8 Million Acres off Texas

The Bureau of Ocean Energy Management (BOEM) will offer 23.8 million acres offshore Texas for oil and gas exploration and development in a milestone lease sale that will include all available unleased areas in the Western Gulf of Mexico Planning Area.

The Western Gulf of Mexico Lease Sale 248, to be held on August 24, 2016, in New Orleans, will be the first federal offshore oil and gas auction broadcast live on the Internet, delivering pertinent bid information immediately to a much broader national and international audience. Through this approach, BOEM aims to promote greater government efficiency and transparency. The livestream broadcast will run at www.boem.gov.

Sale 248 will be the 11th offshore sale in the Gulf of Mexico and the final sale for the Western Planning Area under the Outer Continental Shelf Oil and Gas Leasing Program for 2012 to 2017.

Centurion, ATR to Merge for
Oil, Gas Rentals, Services

Centurion Group and ATR Group are to merge to create a global player in the oil and gas rental equipment and services market. The group, which will have a combined turnover of over £100 million, will operate from bases in the U.K., Netherlands, Caspian, Singapore, Australia and the U.S. It will continue to be headquartered in Aberdeen with ATR’s Chief Executive Keith Moorhouse and Chief Financial Officer Euan Leask becoming CEO and CFO, respectively. Centurion’s acting CEO Peter Stuart will take on the role of chairman of the combined entity, while Alan MacLeod, Centurion’s CFO, will assume the role of director of integration.

Centurion Group provides specialist rental equipment and services on a global scale to the oil and gas and the mining sectors.

ATR Group is involved in the rental, sale and inspection of specialized equipment to the petrochemicals, marine, subsea and offshore oil and gas industries.

Compliance for New
Well Control Rule

The “Oil and Gas and Sulfur Operations in the Outer Continental Shelf-Blowout Preventer Systems and Well Control” rule, published by BSEE in April, set July 28, 2016 as the date when operators must be in compliance with most of the new regulations.

The rule enacts the recommendations of the Deepwater Horizon commission and formalizes standards that are widely seen as industry best practices.

A number of requirements will be phased in over several years, allowing as much as seven years before implementation of the final phase.

Some of the major provisions in the rule include mandates that require blowout preventer systems equipped with both drill pipe centering technologies and dual shear rams, rigorous third-party certification of shearing capability, real-time monitoring of higher-risk drilling operations, and reporting of safety equipment failures in order to address potential systemic problems in their early stages.
