TechnipFMC in high demand

Energean Oil & Gas has awarded TechnipFMC an iEPCI (integrated engineering, procurement, construction, and installation) contract for the Karish gas field development in the Mediterranean Sea offshore Israel. Water depth is 1,750 m (5,741 ft). The scope covers the design, procurement, construction and installation of the subsea system; an FPSO which will also be designed to accommodate production from the later subsea tieback of the Tanin gas field; the subsea pipeline system; and the onshore pipeline and valve station at the receiving station in Israel.

Hallvard Hasselknippe, president of TechnipFMC’s Subsea business, said: “Our strong value proposition builds on early involvement and integrated solutions. By simplifying subsea field architecture, we help our clients significantly improve their project economics.”

LLOG Exploration awarded TechnipFMC an iEPCI contract for the Who Dat field in the deepwater Gulf of Mexico. This includes the delivery and installation of a multi-phase pumping system, including a manifold, umbilical termination assembly, power umbilical, jumper and topsides control equipment.

The 2MW 10ksi multi-phase pump station is optimized for the high gas content in the field. The station leverages field-proven pump hydraulics with TechnipFMC’s high-speed permanent magnetic motor technology and subsea system design. This, the company claims, provides operational flexibility in subsea boosting.

The Who Dat field is in Mississippi Canyon blocks 503, 504 and 547 in 945 m (3,100 ft) of water. Production began in December 2011.

Sabah Shell Petroleum awarded TechnipFMC an EPCI contract for the Gumusut-Kakap Phase 2 project offshore Sabah, Malaysia. This covers supply and installation of subsea equipment including umbilicals, flowlines, and the subsea production system.

Hasselknippe added: “This award demonstrates the added value of our unique integrated offering (iEPCI) and brings TechnipFMC’s integrated model to the Asia/Pacific region.”

Subsea 7, Ocean Installer win Askeladd assignments

Statoil has issued two installation contracts for the Askeladd gas field development in the Norwegian sector of the Barents Sea.

During summer 2019, Subsea 7 will lay a 44-km (27-mi), 20-in. pipeline that will tie Askeladd to the Snøhvit field infrastructure. Support operations will be based in Hammerfest and other locations.

Ocean Installer will install two subsea templates in 2019, followed in 2020 by a 42-km (26-mi) umbilical, a 35-km (22-mi) MEG (mono-ethylene glycol) pipeline and two manifolds.

In addition, Ocean Installer will fabricate and install four spools and protective structures and conduct tie-ins and ready-for-operation activities, with main mobilization performed from Hammerfest.

Askeladd, which is due to start production start at the end of 2020, will extend plateau production at the Hammerfest LNG plant. Development calls for three wells and two new subsea templates - to be provided by Aker Solutions - with spare slots for future wells.

BP signs C-Innovation for IMR work in the Gulf of Mexico

BP has awarded C-Innovation LLC (C-I), an affliate of Edison Chouest Offshore (ECO) and its family of companies, a three-year contract forsubsea construction, inspection, maintenance and repair (IMR) and logistics services in the Gulf of Mexico. With Port Fourchon, Louisiana, serving as the home port, the new contract will bring together ECO’s fleet of multi-purpose platform supply and well intervention vessels with C-I’s ROV, tooling, project management, and engineering services. The scope of work includes: jumper installations; subsea tree installations; facility underwater inspections in lieu of dry-docking; commissioning of new assets; and general field support.

David Sheetz, manager of C-I’s Subsea Division, said: “This is a very large and significant contract for C-I and it helps solidify our reputation as a true, single source for subsea solutions with the backing and support of the diverse family of companies within the ECO group. C-I’s ability to offer a complete suite of services allows clients to have a single point of contact for all projects, which makes budgeting easier, saving time as well as money.”

Forum unveils XLe electric ROV

Forum Energy Technologies has developed a new range of electric ROVs. The XLe, designed and manufactured at the company’s Kirkbymoorside complex in northern England, is the first and smallest of the new range. However, it is sufficiently powerful to undertake subsea maintenance and repairs using its optional electric or hydraulic five-function manipulator arm.

According to the company, the vehicle’s self-regulating power feature compensates for tether losses, ensuring a constant and stable power delivery to the vehicle regardless of the length of the tether.

It employs the same Forum Integrated Control Engine (ICE++) that features in the company’s larger work-class and trencher vehicles. This is said to provide a wide range of auto-pilot and pilot assist modes when appropriate sensors are fitted.

A control electronics pod fitted to all the XLe electric vehicles provides superior connectivity and expansion capabilities to other ROVs, Forum claimed, while ethernet interfacing is said to allow for seamless integration with other sensors.
