Following the Building with Nature concept, a pilot study was conducted introducing finegrained dredged sediments as a semicontinuous source of mud into a shallow tidal channel, naturally dispersing sediment to nearby mudflats and salt marshes.
Crews routinely perform vessel to vessel transfers, ensuring a project continues seamlessly. But the operation is not risk free. A roundtable of IADC members shared ideas on how to improve procedures to make crew transfers safer.
‘What will “sustainability” be in ten years? Our industry needs to be prepared for that.’ Luc Vandenbulcke kicked off 2019 in his new role as CEO of DEME Group. After 21 years working within the group, with 14 of those years starting up, leading and growing the group’s offshore subsidiary, he is now heading the company’s future as it navigates the evolving processes of sustainability.
Numerical investigation of the head and unsteady flow characteristics of a dredge pump loading high-concentration sands
The head of a dredge pump is an important performance parameter and a strongly fluctuating head may affect the operating stability of the pump unit. The IADC Young Author’s Award paper analyses unsteady characteristics of pump performance to improve control of the dredge pump.
