Indonesia Processing Requests for Deep-sea Mining Waste Disposal

plant in neighboring Papua New Guinea spilled red mud into the sea last year due to an operational failure.Indonesia was a major nickel ore exporter until last year, before the government stopped exports in January to support the development of domestic smelters.The government is keen to produce stainless steel and battery-grade chemicals from nickel laterite, and eventually manufacture batteries and electric vehicles.Environmentalists, however, are concerned such developments will damage the local ecosystem.“Two companies have requested deep-sea tailing permits. One is based on Obi Island and

with a new software package called WaveConfigurator, enabling system set up and diagnostic monitoring by end users in the field. Unlike its predecessor, the WaveRadar REX2 incorporates an LCD screen for instantaneous sensor measurement display, as well as status and health data. It has a complete stainless-steel and Polytetrafluoroethylene (PTFE) external construction, making it virtually maintenance-free, and highly resistant to corrosion or extremes of temperature or humidity.The WaveRadar REX2 is fully backwards compatible with all existing REX installations. It includes a new suite of hazardous

Subsea Umbilicals Demand Hit by COVID-19

However, this short-term relief may not last long as the global economy recovers from the Covid-19 pandemic,” says Rystad Energy oilfield service analyst Henrik Fiskadal.Not the same downturnThe materials most commonly found in the manufacturing of umbilicals are high-grade stainless steel, carbon steel armor wire, hydraulic hoses, power cables, fiber optic cables and thermoplastic resins. In addition to the materials, engineering labor is the next largest cost input involved in the manufacturing of umbilicals. Therefore, the more complicated and unique is the design, the more

Sandvik Wins Mero Steel Tube Umbilical Order

Sandvik reports it has won the first large-scale stainless steel umbilical tube order in Brazil’s pre-salt Mero oilfield.Mero is an expansive pre-salt oilfield in the Santos Basin offshore Rio de Janeiro with immense oil production potential. The Mero oilfield is being managed by the Libra Consortium, made up of a partnership between Petrobras, Total, Shell Brasil, CNPC and CNOOC Ltd.The first phase of the project - Mero 1 - is an ultra-deepwater project consisting of 17 wells in a water depth of approximately 2,000 meters.According to Sandvik, the stainless steel umbilical tube order contract

OSIL Giant Piston Corer for CSIRO

The Commonwealth Scientific and Industrial Research Organization (CSIRO) in Australia have purchased a 24m Giant Piston Corer system for the RV Investigator from Ocean Scientific International Ltd (OSIL).The modular deep sea sediment coring system comprises four 6m-long barrels, a stainless steel head with removable lead weights and a mechanical trigger arm with 1m long pilot core. The system has been specified with deck stands, deck storage for the head and barrels and a comprehensive package of tools and spares.The OSIL Giant Piston Corer systems can achieve recovery rates of over 95% in soft

200mm of overlying supernatant water), and the corers can easily be fitted with core tubes of varying diameters by swapping out the mounting assembly. The frame of the corer can also be split in two to facilitate shipments where height restrictions are a known issue.The system is constructed from stainless steel and features detachable core assemblies, which enables the core tubes (or if necessary the entire core tube assembly) to be removed from the corer for analysis or storage. The core tubes are sealed top and bottom once the sample has been taken, allowing rapid retrieval of the corer without jeopardizi

With the Subsea Link, they can effectively source an ROV load shackle as they would any other standard product in our portfolio.”Renewable energy and offshore personnel will be among those to note the Subsea Link’s construction from 17-4PH stainless steel and resistance to saltwater, temperature variations and the incredible water pressure experienced at such sea depths. As stated, it can be handled and rigged via an ROV where a location may be inaccessible or it deemed cost-prohibitive to use divers. Several output options are available: mV/V
