Fugro Helps Prep for
Offshore Wind Centre

Fugro has completed offshore works undertaken in preparation for full construction of the European Offshore Wind Deployment Centre (EOWDC) at Aberdeen Bay, Scotland.

The geotechnical site investigation took place at 11 turbine locations to assess the seabed, with the data acquired being used to inform the final design and micro-siting of the turbine foundations. Full offshore construction is scheduled to start in late 2017 or early 2018, after an investment decision later this year.


Materia, Aegion to Supply
Appomattox Pipe Insulation

Materia, Inc., in conjunction with Aegion Corp., has been selected by Shell Offshore, Inc. to supply pipeline insulation materials for the Appomattox development in the deepwater Gulf of Mexico.

The insulation system provides an effective thermal barrier between flowlines and seawater. The thermosetting cross-linked hydrocarbon polymer maintains structural integrity as an incompressible solid at water depths greater than 10,000 ft.


Harris CapRock Comms
For Brazil Offshore Assets

Harris CapRock Communications was selected by Technip to provide turnkey, fully managed communications services to six offshore assets operating in Brazil’s Campos, Espírito Santo and Santos basins. The long-term contract covers remote communications supported by VSAT technology over C-band satellite with up to 7 Mbps of bandwidth delivered to support network traffic through Harris CapRock’s teleport in Macaé.

In addition to corporate applications, Harris CapRock will provide backhaul backup, VoIP backup, wireless area network (WAN) optimization and a certified field technician dedicated to managing Technip’s application testing, license facilitation, network performance, systems operation and maintenance, as well as teleport and IT operations.

The oil and gas assets to receive reliable communications include two drilling vessels stationed in the Campos Basin and four supply vessels carrying ROVs that will continually move between the offshore regions throughout the service period.


TerraSond to Map
Sinkholes, ID Seeps

TerraSond has been awarded a contract to map offshore sinkholes and identify potential gas seeps. The data collected in conjunction with near-surface seismic provides information for the impact assessment of sinkholes on the water supply of South Florida.

Using a unique underwater mass spectrometer for in-situ chemical analysis eliminates the traditional issues of handling, transportation, storage and analysis of samples typically performed in a laboratory.

An AUV will support the seafloor mapping and seep detection, given the depths and currents at this location.


Statoil Unveils Cap-X
Subsea Tech Concept

At the Barents Sea Conference in Hammerfest, Norway, Statoil presented a new subsea concept developed by Statoil, called Cap-X, which aims to drive subsea technology development on the Norwegian Continental Shelf.

Cap-X is intended to bring the industry one step closer to a plug-and-play solution on the seabed. It combines existing and new technology, is one-quarter the size of today’s subsea templates and enables more operations from vessels instead of rigs.

The technology increases the efficiency of horizontal drilling in shallow reservoirs. The main structure can be produced in shorter time by a larger number of suppliers, with potential for local production.


Reaffirming Arctic Offshore
Structure Standards

The U.S. Bureau of Safety and Environmental Enforcement (BSEE), in partnership with the University of Alaska, completed a research study that examined the ability of current offshore structural designs to successfully survive sea ice demands under extreme Arctic conditions.

The objective of the study, “Reliability-Based Sea Ice Parameters for Design of Offshore Structures,” was to produce information that would supplement current standards and recommendations, such as ISO 19906 Standard: Petroleum and Natural Gas Industries - Arctic Offshore Structures, to provide additional sea ice information for the Chukchi and Beaufort Seas.

BSEE’s Technology Assessment Program ensures that industry operations offshore incorporate the best available and safest technologies as required by the Outer Continental Shelf Lands Act and Energy Policy Act.

Over a two-year period, researchers gathered data from 16 seasons of ice measurements from the Chukchi and Beaufort Seas. This provided sufficient comparisons of various sea ice parameters, such as first and last ice occurrence, level of ice, rubble fields, ridges and ice movement.

The study identified critical keel depth and provided an assessment of the suitability of the current ISO 19906 recommendations for estimating global ice forces on offshore structures. Researchers concluded that the current standard of practice cited in ISO 19906 is conservative for current structural design parameters and is capable of surviving the demands from sea ice.

There are currently seven studies ongoing that assess offshore engineering technology and conditions in the Arctic. All of these efforts assist BSEE in understanding how conditions in the Arctic could impact future regulatory standards.


OTC Award for Teledyne
EOFL New Tech

Teledyne Oil & Gas received the “Spotlight on New Technology” award from OTC, recognizing products with potential to make a significant impact on the oil and gas industry.

The winning technology is an Electrical Optical Flying Lead (EOFL) comprising a Nautilus Rolling Seal Hybrid Wet Mate Connector and a seven- or 12-way Nautilus Electrical Wet Mate Connector on either end of a subsea jumper assembly. A qualified electrical/optical converter is embedded into the PBOF hose. The system helps optimize subsea data transmission network architecture, potentially reducing operational costs and system complexity.
