Offshore & subsea

The jack-up drilling rig HAKURYU-11 started the drilling operation based on the subcontract with PetroVietnam Drilling & Well Services Corporation on 19 November at Vung Tau, offshore Vietnam.

Energy companies using the system will be able to access a reliable supply of up to 100 MW of power over distances of up to 600 km and at a depth of 3000 m via a single cable, paving the way for greater access to offshore hydrocarbons.

The Senegal North Ultra-Deep Offshore (SN-UDO-19) 3D survey will covers over 5100 km2.

The one-month project for Shell will commence in 4Q19 and will cover an area of approximately 600 km2 in the western Black Sea.

The three-year extension will see Rever Offshore secure exclusive and uninterrupted access to the DSV Rever Topaz from long-term partner Volstad Maritime until December 2022.

Most of the supply growth next year in the Gulf of Mexico will come from deepwater projects, according to the energy research and consulting firm.

The drill stem test flowed dry gas from the intra-Muda sands at a rate of 11.4 million ft3/d on a 181/64-in. (2.8 in.) choke, maintaining a wellhead tubing pressure of 225 psi.

The transaction entailed the sale to SBM Offshore of Constellation’s equity ownership in the lease and operating companies related to five Brazilian FPSOs.

As the project’s main automation contractor, Honeywell will deliver all systems, detailed engineering and lead procurement for the integrated control and safety system.

Maersk Supply Service will provide the full scope from site preparation, installation of pile anchors, tow of the FPSO, through to final hook up operations.

The new recommended practice aims to streamline manufacturing processes and significantly reduce lead-time and cost.

Dan Munro, PJ Valves, explains why the anticipated rapid growth in the FPSO market will mean operators and contractors will need to change in various ways in order to deliver on the sector’s promise – particularly in supply chain relationships.

Planned to start in early 2020, the survey has already received significant industry interest and is being prefunded in part by BP.

The contract will see Bourbon Marine & Logistics support Total E&P Namibia a deep offshore exploration campaign in southern Namibia in 2020.

Production optimisation specialist, Enpro Subsea, has completed two subsea hydraulic intervention campaigns for two operators in West Africa.
