Clough java constructor1/23/2024 ![]() "We are excited about the inclusion of this vessel into Clough's subsea construction fleet," said Mr. Kevin Cain, Chief Operating Officer of Clough's Offshore Oil & Gas Business Unit welcomed the vessel acquisition. The vessel will be equipped with a fully integrated diesel electric propulsion system, dynamic positioning class DP2, a deepwater crane of 200T, an advanced ROV launch and recovery system for 2 Work Class ROV's and a 12 man saturation diving system. The vessel is designed for construction, subsea operations, diving and ROV services and will have a work deck area aft of the ROV section of approximately 1150 m2. Measuring 117.35 meters long, with a beam of 22 meters, the vessel is being built with accommodation for 120 people. The vessel is an advanced multi-purpose subsea construction vessel, developed in cooperation with owner and yard. Once operational the vessel will be deployed on various projects and contracts, primarily in the Australasian and SE Asian regions. The as yet unnamed vessel will be ready for service in June 2008. Three Vietnamese banks namely Vietnam International Commercial Joint Stock Bank (VIB), Asia Commercial Bank (ACB) and Saigon Hanoi Commercial Joint Stock Bank (SHB) provided a loan of approximately $51m for the field’s development.Clough Limited has entered into an agreement for an eight year charter of a new subsea operational support vessel. The control modules for the WHP were supplied by Satech System Automation. Clough also supplied the pipe components for the project.ĪBB supplied its System 800xA control system, Plantguard emergency shutdown system, Plantguard fire and gas detection system, a wellhead control panel with hydraulic power unit, the telecommunications equipment required for the WHP and CPP3 platforms, and the power generation systems for the WHP. The WHP and the subsea pipelines were installed using Clough Thailand’s derrick pipelay barge Java Constructor. The engineering, procurement and construction (EPC) contract for the WHP’s topsides was awarded to Vietsovpetro, who worked in collaboration with EDG Consulting Engineers.ĭetailed engineering design of the pipelines and risers, additional engineering, and construction management services were performed by Cronus Technology. Contractors involved with the Vietnamese oil and gas field HVJOC plans to resume drilling the well in 2015. They were, however, suspended in late 2014 due to unexpected geological issues. The project aims to access the undrilled south-western corner of the field and maintain a consistent production level from the field.ĭrilling activities for the CNV-7P development well started in April 2014 using the Naga 2 rig. ![]() ![]() HVJOC further received regulatory approvals for the Full Field Development Plan for CNV, which includes the drilling of the CNV-7P development well from the Vietnamese government in the first half of 2013. The crude oil is processed and stored in a floating storage and offloading (FSO) vessel near Bach Ho field and supplied to refineries, while wet gas separated offshore is transported to an onshore gas facility and sold to PV Gas for use at the Phu My power plant. ![]() The field achieved a milestone in December 2011 when it reached its 2011 crude oil production target of 128% without any lost time injuries and incidents. The second phase of development drilling at the field started in April 2010 and involved the drilling of an additional well by Scorpion Offshore’s Offshore Resolute jack-up rig. The field currently has five producing wells, all of which were drilled using PetroVietnam’s PV Drilling 1 rig. Two 26km-long and 10in-diameter subsea pipelines connect the two platforms. The development involved the installation of an unmanned wellhead platform (WHP) tied back to Vietsovpetro’s CPP3 central processing platform at Bach Ho field in Block 9-1 and the development of four production wells. The Field Development Plan (FDP) was approved in December 2006. It was further appraised and was declared commercial in April 2006. The field was discovered in October 2002 following the drilling of three exploration wells. The field is estimated to have a production life of approximately 20 years. The field started production in July 2008 at an initial rate of 8,000 barrels per day of oil and 20 million metric standard cubic feet per day (MMscfd) of gas.
