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.

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.

Oil, debris skimming boats

Elastec/American Marine (USA) has delivered two custom oil and debris skimming boats manufactured in Europe to a major client in Asia. The 10 m (32-foot) craft is capable of collecting, storing and transporting recovered oil and debris.


The boats were built after many months of consultation and are a development of an early skimming pontoon concept. The thoroughly updated design encompasses a number of important operational features that allow these boats to collect and transport floating garbage as well as skim and collect floating oil, should an accident happen.

Trelleborg launches new subsea vibration suppression system

Trelleborg Offshore has launched an innovative new vortex induced vibration (VIV) system.  The high performance T-Strake features a unique modular design enabling more efficient transportation and installation.

James Vultaggio, vice president engineered products, Trelleborg Offshore, commented: “Pipelines unsupported over free spans, such as steel catenary risers and rigid steel flowlines, are prone to VIV fatigue, which can cause serious performance issues such as pipe girth weld failure or premature pipe malfunction. To combat this, the T-Strake comprises overlapping and interlocking moldings, with three-start helical strakes to provide an effective triangular or trapezoidal strake profile.”

3.5MW subsea electric motor tested successfully

Flowserve Corporation has announced the successful completion of full load performance testing of a 6.6 kV, 3.5 MW, high-torque subsea electric motor. This 4-pole motor is one of the world's largest oil-filled motors designed for subsea applications. The Flowserve facility in Hamburg, Germany, engineered and built the motor using the combined technology of the Flowserve Pleuger and Byron Jackson brand submersible designs. The high-power motor is designed to enable the oil and gas industry to produce ultra-deep subsea fields and is part of a larger technology advancement initiative to develop high-pressure multiphase boosting for subsea applications.

"The successful completion of the test brings higher driver power levels to the subsea market than were previously available," said Dr. Andreas Dreiss, director, advanced technology. "The motor also demonstrates the ability of Flowserve to develop new technologies that provide solutions to the most demanding challenges our customers face."

Reflex Marine celebrates 10th anniversary of FROG crew transfer device

Reflex Marine is celebrating the 10th anniversary of its groundbreaking FROG crew transfer device. According to the company, more than 450 FROGs are now used in all the world’s major oil producing regions including Europe, the Middle East, West Africa, the former Soviet Union and the Gulf of Mexico.

Reflex Marine says the device has set the industry standard in marine transfer. It accounts for around 1 million crew transfers each year and the number is increasing. The grounding of helicopter flights in the North Sea, because of the volcanic ash cloud this past spring, led to a significant rise in demand for FROGs and heightened awareness of marine-based crane transfer as a viable alternative transfer solution. That incident, along with an increase in awareness among operators of the various options as well as advances in crew transfer, has created an increased acceptance of crane transfers as both a first-line and contingency option for moving personnel offshore.
