IKM Subsea Singapore said it has kicked off 2018 with a double contract award.   The first is a contract to provide two remotely operated vehicles (ROV) for a floating liquefied natural gas (FLNG) mooring installation in Bangladesh. IKM Subsea provided one Merlin WR200 and a Comanche with the necessary toolings onboard the vessel Jumbo Javelin. IKM said it was chosen due to previous experience with the client, Jumbo Offshore, and the ability to perform in strong weather conditions in Bangladesh. With the Merlin WR200, the operating weather window is extended to help and execute the project.

Marine Hazards to Subsea Cables and Pipelines

In February 1989 the RoRo vessel Vinca Gorthon ran into heavy weather and sank off the Dutch coast. She landed on an oil pipeline that was severely damaged. Although the probability of sinking on top of a pipeline is very small, the incident showed that it can happen.   Shipping traffic can represent a potential hazard to subsea pipelines in various ways, such as sinking or grounding, lost containers or an anchor hooking onto a pipeline. Over the years MARIN has contributed to the development of a method by which the burial depth of a cable or pipeline is determined on the basis of actual

indicated that tidal current near the site can run at up to 2.5 meters per second providing an ideal site for harnessing tidal energy. Diesel generators currently provide all of the electrical power for the wood chipping operation and supporting infrastructure.   “This endeavor to introduce marine renewable energy on a logging site plays well with our commitment to sustainable carbon-neutral forest management,” Muljadi Tantra, Deputy Managing Director of GFPT explained. “PT BUMWI has been a pioneer in this, and is one of the first mangrove concession to obtain the Forest Stewardship

BISSO MARINE Completes GoM Dive Campaign

Full service offshore and subsea infrastructure services contractor BISSO MARINE said it has completed a two-month saturation diving campaign in the U.S. Gulf of Mexico. Using its 126.4m x 30.4m construction barge Bisso Subsea Vision, configured with a 12-man ABS Classed 300m saturation system, BISSO MARINE performed a variety of subsea infrastructure services including several subsea abandonments in water depths ranging from 91m to 220m.   Other scopes of work included a Reverse 'J' recovery of several miles of unpiggable 6" pipeline from 122m of water.  The 6" pipeline was

FlexMoT for Monitoring & Detection of Offshore leaks

Leaks on offshore platforms present a hazard to the marine environment and human health. The monitoring system FlexMoT will detect irregularities and provide a warning system for disasters. The system was presented at this year’s OCEANS’16 in Monterey.   (Rostock/Darmstadt/Graz) Accidents in offshore oil & gas drilling are dangerous. The damage caused by the Deepwater Horizon oil spill in the Gulf of Mexico five years ago shows how high the costs can be for nature and those responsible. Now, a solution was presented at this year’s OCEANS Conference.   FlexMoT is an

to discover new sources of the rare metals critical for low carbon technologies. HR Wallingford scientists, Jon Taylor and Neil Crossouard are on board the research vessel as it heads south west from the Canary Islands to the Tropic Sea mount, where a forty day investigation will use robotic submarines, autonomous seafloor instruments and drilling to answer questions about what controls the formation of marine mineral deposits on the floor of the North East Atlantic. E-tech elements, such as cobalt and tellurium, which are essential for emerging renewable energy technologies, are in short supply
