Sabah Blocks J and K
Landmark: First Malaysian subsea project engineered and manufactured from FMC's Malaysian facilities
The Gumusut-Kakap field is located northwest offshore of Sabah, Malaysia. Gumusut-Kakap will utilize FMC’s 5”x2” 10K EVDT tree system configured in different ways to accommodate the needs of the field. All trees will be provided for API Material Class HH utilizing CRA cladding on all production-wetted surfaces. The maximum flowing temperature condition is 210 F (99 C) and anticipated flowing pressures up to 6,000 psi.
The project will utilize the modular EVDT tree concept with standardized tree materials allowing for interchangeability for production, water injection and gas injection tree styles. The primary difference is the FMC retrievable flow control module (FCM) which allows easy conversion between tree systems to allow project flexibility. The production FCM includes a bolted bonnet choke with multiphase meter packaged in a single unit and included insulation to achieve a 10-hr thermal cool-down performance.
The project will provide Shell with state-of-the-art high-speed communications using FMC 200e protocol. FMC's 200e system provides a minimum communication rate of 9600 with full duplex point-to-point communications. This enhances the performance of data flow between the FPS and subsea architecture, and the system is designed to operate and control up to 40 SCMs, which will cover the current requirements and future phases.
The field comprises three unique manifold styles. Three production manifolds are provided with dual 8-inch headers and 6-inch branches completed with API material class HH trim components and Novolastic insulation for production, water injection and gas injection configurations. The manifold utilizes hydraulically actuated M3000 valves controlled by a manifold mounted subsea control module. The jumper connection systems utilize field-proven Torus-III connector systems with integral hydraulics and MC metal-to-metal gaskets.
