Smallest VSAT antenna and world’s first satellite messenger

Data Technology Solutions recently introduced the smallest VSAT antenna and SPOT, the world’s first satellite messenger.

The new mini-VSAT Broadband service uses sophisticated spread spectrum technology to provide vessels with data reception rates as fast as 2 Mbps and data transmission rates as fast as 512 Kbps via a 24” KVH-developed marine terminal. The first fully integrated maritime VSAT system works seamlessly by combining innovative and revolutionary technology, including rugged, fully stabilized antenna technology from KVH Industries, powerful KU-band satellite networks, and ViaSat’s ArcLight spread spectrum mobile broadband technology. The world’s first satellite messenger. SPOT is the only device of its kind, using the GPS satellite network to acquire its coordinates, and then sending its location – with a link to Google Maps – and a pre-programmed message via a commercial satellite network. SPOT can be used for commercial lone worker safety applications for those businesses with employees operating in remote areas outside the range of cellular and other wireless communications. It is also a valuable safety tool for any person who drives outside of cellular coverage or for emergency messaging when cellular or land-based communications may be damaged or unavailable. And because it uses 100 percent satellite technology, SPOT works around the world – even where cell phones don't.

60 years of servicing offshore operations to be marked at OTC

McCrometer’s exhibit at OTC will feature a flow demonstration unit. This live demo will show how the V-Cone Flow Meter conditions flow unlike any other flow technology. Conditioning the flow in the pipe ensures accurate, reliable dP flow measurement in any environment.

With its unique differential pressure (dP) cone design, the versatile V-Cone Flow Meter and highly scalable Wafer- Cone Flow Meter provide superior flow measurement accuracy and repeatability regardless of space and weight constraints. McCrometer’s field-proven flow measurement solutions have met the demanding production environment of the oil and gas industry for more than three decades.

Standalone Training Units Make Learning Easier In Offshore and Remote Locations

Since Dolphin Geophysical deployed the ConTrainer from Oilennium Ltd. on its global fleet of seismic vessels, the company has experienced a dramatic improvement in its ability to deliver quality, consistent Health, Safety and Technical training to its crews offshore. The ConTrainer, a standalone Learning Management System (LMS) that features comprehensive training content for the oil and gas industry on a small computer system, is the only one of its kind to offer eLearning modules offshore and in remote locations.

Developed by Oilennium, the ConTrainer was created in response to demand from oil and gas companies seeking to provide interactive learning for employees working in remote locations where access to the internet is intermittent.

Range of subsea solution advances

At the Australasian Oil and Gas Exhibition in Perth, Australia, Trelleborg presented a number of advancements in its flowline protection solutions including its T-Strake, an innovative new vortex induced vibration (VIV) system as well as subsea flow control developments, including its entire line of high performance Vikotherm insulation materials.

“In increasingly rougher seas, pipelines unsupported over free spans are prone to VIV fatigue. This is a growing concern as VIV can lead to serious issues such as pipe girth weld failure or premature pipe malfunction. We designed our T-Strake flowline protection to suppress the effects of these vibrations on pipes to avoid damage and downtime,” said Trelleborg key account manager within offshore, Iain Green. “Similarly, our Vikotherm insulation range ensures superior joint strength, reduced thermal conductivity and increased heat capacity, as well as flexibility and resistance to hydrostatic collapse down to more than 3,000 metres. As environments offshore grow harsher and exploration is going deeper, the need for thermal insulation solutions to perform in these extreme environments becomes increasingly more important.”

Subsea Processing In The Face Of Low Oil Prices

For the majority of people, recent low oil prices have simply meant a cheaper visit to the gas pump. For those who are focused on extracting and processing future fuels, however, this recent reduction in the price of a barrel of oil could have much further reaching effects.

As a somewhat nascent technology, subsea processing is perhaps the next leap forward in fuel extraction techniques. Rather than placing exposed facilities on the surface of the sea, the subsea approach dives under the waves. Away from temperamental weather conditions, these facilities are able to extract oil right on the ocean’s floor. Despite huge potential, however, these facilities could fall victim to the fluctuating prices of oil.

DNV GL Cooperation with Industry to Address Risks from Offshore Co2 Pipelines

Offshore carbon dioxide (CO2) pipelines could potentially pose a risk for offshore infrastructures, ships and the marine environment. To demonstrate that CO2 pipelines can be operated safely and to ensure the risks are well understood, industry stakeholders have asked DNV GL to initiate a Joint Industry Project (JIP) “CO2 Subsea Releases - Small Scale Experimental Programme’’. Several major operators have already joined the ‘Sub-CO2’ JIP including: National Grid, ENI, and Petrobras, but there is still time for others to join.

The number of offshore CO2 pipelines is expected to grow significantly in the future, as Carbon Capture Utilisation & Storage (CCUS) technology is deployed to mitigate CO2 emissions from power plants or other large industrial sources such as steel or cement factories.

DNV GL Launches A Joint Industry Project to Combat External Onshore-Pipeline Corrosion

Asle Venås - Pipeline Segment Director at DNV GL

Microbiologically influenced corrosion (MIC) is a serious threat to the integrity of onshore transmission pipelines and can lead to unexpected failures. Despite advances in understanding, there is limited knowledge to accurately predict its location and the rate of corrosion. For this reason, DNV GL is calling for partners to collaborate in a Joint Industry Project (JIP) to develop a Recommended Practice for the detection and mitigation of MIC.

External MIC is corrosion caused or promoted by microorganisms on the outside of the pipeline system and is one of the leading causes of corrosion failures in onshore pipelines. Microorganisms may adhere to metal surfaces and form biofilms (complex microbial ecosystems) that can alter the electrochemical conditions on the metal surface in such a way that corrosion can be induced locally; most commonly occurring as pitting. It is difficult to prevent this type of rapid corrosion, since it is not possible to prove the presence of MIC directly without excavating the suspected site to run tests. Indications of MIC can be found through detecting either coating degradation using DCVG (Direct Current Voltage Gradient) or the pipeline's metal loss using ILI (In-line Inspection).

Ultradeep Drilling Scientifically Explores Seismogenic Zones

In an effort to better understand geologic processes occurring at tectonic plate boundaries, scientists around the world are drilling deep beneath the seafloor. Their targets are seismogenic zones 5 to 40 km [3 to 25 mi] below the Earth’s surface where devastating subduction zone earthquakes originate.

From 2003 to 2013, the Integrated Ocean Drilling Program functioned as an international marine research drilling platform dedicated to advancing scientific understanding of the Earth by monitoring and sampling subseafloor environments. By studying core samples retrieved from these zones, scientists hoped to clarify how material properties and stress fields affected fault slip, which could potentially propagate to the seabed and become tsunami-generating earthquakes.

To cater for industry demands, Trelleborg’s offshore operation has consolidated its range of high performance thermal insulation materials, to house them all under one brand – Vikotherm. The company will present its newest portfolio at ONS, in Stavanger, Norway.

“As subsea environments become increasingly more demanding; going deeper and further than ever before, temperatures and hydrostatic pressure become much greater,” commented Oddvar Kopstad, Sales Manager with Trelleborg’s offshore operation. “As a result, the demand for more sophisticated products which can cope with these harsher environments is growing. And this is certainly the case with our thermal insulation materials; so we’ve taken the strategic decision to group all of our solutions together to allow for easier product selection and ensure that all customer needs can be met in one place.”
