Low Gravity on Ocean Worlds Might Help Sustain Warm Water Circulation
of discharging fluids compared to what would be found on Earth.Planetary scientists are looking to observations from satellite missions to help determine what kinds of conditions are present or possible on ocean worlds. The author team for the new paper will be attending the launch of the Europa Clipper spacecraft at Cape Canaveral, FL later this fall, along with colleagues collaborating on the Exploring Ocean Worlds project.According to WHOI’s German, who is also co-author on the paper, “A significant outcome from this study is that it suggests that low temperature (not too hot for

then back rush up through the seafloor, much as the way that it happens on earth in hydrothermal vents. We’re working with JPL to work out how we would communicate, even (underwater) vehicle to vehicle, back up to the surface lander, back to Earth,” says Shank. Near-term, NASA's Europa Clipper mission will send an orbiter to study the moon during a series of flybys, while in orbit around Jupiter. Planned launch is 2024.Of course, that’s not the sole goal. There’s just as much to discover on Earth in the underexplored Hadal Zone (6,000-11,000 m deep), says Shank. “Right
Global Offshore to Take Care of Cables at Equinor's Offshore Wind Farms
cable management services and carry out associated call-off services, comprising of active cable maintenance as well as unplanned repairs. The agreement gives Equinor access to Global Marine Group’s fleet of cable ships and CTVs, including its cable laying ships, Global Symphony and Normand Clipper, equipped with one of Global Offshore’s Q1400 jet trenches."A first for Global Offshore, which traditionally carries out work on offshore cables, the framework agreement covers the onshore and offshore export cables at Equinor’s Dudgeon wind farm, as well as the offshore export
Global Offshore's Pre-Lay Plough Passes Kriegers Flak Test with Flying Colors
, with delivery to coincide with the Danish Kriegers Flak project start, the plow minimizes the operational risk and total time required to install subsea cables, Global Offshore said.Overall 72 routes have been completed, totaling approximately 158 km, supported by the Global Symphony and Normand Clipper undertaking boulder picking in the densely populated boulder fields. Despite the tough conditions, the PLP240 has achieved target trench depths in the majority, going over and above the project requirements, up to 1.7m in a large portion of the site.The first of 72 foundations was last month installed
Fugro ROVs for Normand Clipper Vessel
Dutch marine and offshore services company Fugro has won a long-term contract for two remotely operated vehicles (ROVs) and a full survey positioning package on Global Marine Group recently chartered vessel, the Normand Clipper.As part of the contract, Fugro will provide two Fugro core vehicles (FCVs) from their FCV600 model portfolio."The FCV600 is a versatile work-class ROV (WROV) and will allow Fugro to support the Normand Clipper across a range of operations, with primary focus on subsea cable-laying for the offshore utilities and renewables markets," Fugro said.The FCV600 model can be
OSV Powers Up for Deepwater Efficiency the Island Offshore Way
. While offshore wind vessels have developed in line with market growth, part of the decision to produce W2W vessels for oil & gas was based on a less immediate, but potentially significant need.“We are really combining different uses for the oil companies. Our newest W2W vessel, Island Clipper retains most of its original PSV capacities, but we have expanded its capabilities with a flexible gangway that can be mobilised within 48 hours, making it an ideal solution for maintenance on unmanned installations – the number of which is growing in the North Sea. Looking ahead the safe
Global Marine Taps IHC for Normand Clipper Cable Lay Spread
Dutch offshore equipment and vessel builder Royal IHC has secured a contract with Global Marine Group to design and delivery of an integrated power cable lay spread.The equipment will be installed on its newly chartered vessel, Normand Clipper, which Global Marine has chartered from Solstad Offshore.The spread to be supplied by Royal IHC is optimized for inter-array cable lay and includes a patented quadrant handling system for second-end deployment operations, Royal IHC said.The equipment also includes IHC’s 15Te break-back tensioners and an overarching control system."This integrates the
Will 2020 be the year for Subsea Mining?
; polymetallic nodules, seafloor massive sulfides and polymetallic crusts.Polymetallic Nodules were the first of the seafloor minerals to be discovered. These nodules are of commercial interest for their high manganese content. In one area of the North Pacific Ocean seabed known as the Clarion Clipper Zone, the International Seabed Authority (ISA) estimates there are over 20 billion tons of these nodules. Generally, these nodules lie atop ocean sediment at depths greater than 3000 meters.Seafloor Massive Sulfides (SMS) are formed by undersea volcanos and generally lie in shallower water than
