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.

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

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.

Trelleborg's Vikotherm II subsea insulation is applied onto a pipe by the extruding process

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.”

Industry’s First Standard For Certifying Subsea Equipment And Components

The subsea industry is challenged by the high cost levels, complexity and low predictability of quality control requirements throughout the supply chain. DNV GL aims to help address these issues through the launch of a new ‘Standard for certification of subsea equipment and components’. The goal of the certification scheme is to help increase quality control and efficiency, in addition to facilitating projects being delivered as scheduled by shortening lead times.

Major efficiency issues in the subsea sector are the highly variable requirements by operators from field to field and that quality assurance processes are customised on a project-specific basis, which greatly affects cost levels. The DNV GL standard aims to help the interpretation of existing API and ISO standards and the certificate will provide operators with confidence that fabrication quality is being controlled and assured throughout the industry’s complex and distributed value chain.

Successful pipeline pressure isolation in offshore application

TDW Offshore Services AS (TDW) announced that it has successfully completed a series of pipeline pressure isolation operations offshore western Borneo in Malaysia for Sarawak Shell Berhad. The operations were carried out on the Jintan, B11 and F6 platforms in the South China Sea, as part of Sarawak Shell Berhad’s ongoing pipeline valves maintenance program.

Pipeline pressure safely isolated
The first of the three operations took place on the Jintan platform on a 24-inch gas export pipeline that extends from the JNDR-A platform to platform M1 off the West coast of Sarawak. TDW executed a double-block pressure isolation against 90 bar pipeline pressure so that Shell could safely replace a passing shut down valve (SDV). A 24-inch SmartPlug isolation tool was pigged using production gas approximately 30 meters into the pipeline and set at the vertical section of the riser. Throughout the entire operation the SmartPlug tool was remotely operated, monitored and tracked continuously by TDW with its SmartTrack technology. The SmartTrack system, which uses proprietary electromagnetic and Extremely Low Frequency (ELF) technology, provides the operational security required to safely isolate pipelines in a wide range of operating environments. After the topside section was safely depressurized, a spool section was replaced and a new flange welded to it to accommodate the new shutdown valve. TDW utilized a joint tester tool to verify the flange installation prior to Shell installing the replacement SDV. Overall, the affected section was isolated for a period of 13 days at a pressure of 90 bar while necessary testing and SDV installation took place.
