Tata Steel Reaches
Record Depth in GOM

More than 140 km of pipeline manufactured at Tata Steel’s recently enhanced double submerged arc welded (DSAW) mill has achieved an industry first by becoming the deepest to be laid in the Mexican section of the Gulf of Mexico (GOM) at more than 3,000 ft.

The mill has been the focus of significant recent investment to enhance technology and processes and increase power efficiency. More than 125 improvements were completed in 2015 to strengthen its overall operational and performance capability.

Trimming Newbuild Costs
By Creating New Standards

The second phase of a joint industry project (JIP) is underway to further develop the proposed Integrated Offshore Standard Specifications (IOSS) and test their application.

Initiated in 2015, the Korea-based JIP aims to develop common, globally accepted best practices for standardized offshore components and equipment. The first phase successfully focused on the constructability viewpoint and addressed items for structures, piping and E&I. The IOSS will be applied and tested against upcoming offshore development projects.

Phase two of the JIP involves a global constellation of about fifteen partners, including oil majors, fabricators, classification societies, ship yards and engineering companies.

New Company Born From
Harkand Management Buyout

A team led by AJ Jain, Harkand North America Managing Director, has agreed to a management buyout (MBO) of Harkand’s North American and African business. The new company, Ethos Offshore Ltd., will continue to provide subsea engineering and construction services to Harkand’s existing U.S., Mexican and West African client base.

The new company, backed by investment funds advised and managed by Oaktree Capital Management, L.P., is expected to have a contracted backlog of $145 million worth of projects. The move also could potentially safeguard more than 100 jobs across North America, Africa and Mexico.

The MBO has ensured that Ethos Offshore is able to deliver the full scope of subsea services to established clients, including ROV and diving, inspection, engineering, project management and survey services.

Forum Energy Delivers
Nine Custom PLRs

Forum Energy Technologies Inc. has successfully delivered a number of its largest subsea Pig Launchers and Receivers (PLRs) and laydown heads to a project in North Africa. The nine PLRs have been deployed as part of a development of nine subsea wells 4 to 24 in. in size at water depths from 300 to 800 m.

The custom-designed units will be used in the completion of flooding, cleaning, gauging, strength test, intelligent pigging and dewatering activities.

Pharos Renames,
Re-equips Vessel

Pharos Offshore Group secured a 12-month deal for the former Skandi Inspector and is now mobilizing the newly named DP2 Deepsea Worker with a work-class ROV, an observation-class ROV and a subsea excavation spread, ready for 2016/2017 operations.

Aleron Subsea will be Pharos Offshore’s ROV partner during the period, providing a comprehensive vehicle support package, while Pharos operates the equipment.

Among the equipment will be a full Pre-Lay Grapnel Run spread, boulder clearance spread and cable recovery spread.

Fugro Supports BP Wells
In Trinidad and Tobago

Fugro has provided a spectrum of services to BP Trinidad and Tobago LLC (bpTT) to allow safe drilling and completion of five subsea wells in an area of strong currents. The services include wellhead motion (fatigue) monitoring, metocean measurements and positioning services.

The positioning activities were carried out onboard the drilling vessel, as well as on the three supporting anchor handling tugs (one tug had subsea acoustic ROV positioning). Fugro provided bpTT with dimensional control survey services, DGNSS verification, gyrocompass calibration and offset measurements, navigation at the well locations, and final positioning of the drilling vessel within the required tolerance of 3 m.

Aquatic Carousel System
For Umbilical Installation

Aquatic Engineering & Construction Ltd., subcontracted to Bibby Offshore Ltd. to replace subsea infrastructure in the Central North Sea as part of BP’s $1 billion Eastern Trough Area Project (ETAP) Life Extension Project, will deploy its carousel system to install 35 km of umbilical, ensuring electrical control capability between ETAP’s central processing facility and the Machar field.

The umbilical lay campaign is scheduled to commence in June and is expected to last approximately 30 days. This is the first phase of Bibby’s five-vessel campaign, involving trenching, structure and riser installation, followed by electrical diagnostics and commissioning works. Aquatic has also been subcontracted to provide lay equipment and personnel for the riser installation campaign in September.

ETAP, located 240 km east of Aberdeen, is one of the largest and most complex developments in the North Sea, comprising nine oil and gas reservoirs, six of which are operated by BP. The ETAP Life Extension Project will help secure the future of the fields until 2030 and beyond.

CGG Acquires, Processes
Seismic Data Off Gabon

CGG has worked directly with the Direction Générale des Hydrocarbures of Gabon (DGH) to acquire and process over 25,000 sq. km of new 3D BroadSeis multiclient seismic data over available and licensed blocks in the South Basin to enable evaluation of this prospective area. A fast-track pre-stack time-migrated data set for this survey is now available, along with sample pre-stack depth reverse time-migrated (RTM) data in one area. The final RTM for the whole of the survey area will be available this summer.

Although this data set delivers unprecedented images of the subsurface in the area, additional data are being acquired to improve the imaging further in the most complex geology to the southeast of the survey.
