project description

The EVA-North Malay Basin Gas Delivery System (ENGDS) Pipeline Installation Campaign was carried out under the Transportation and Installation of Offshore Facilities for Year 2014 – 2016 by GOM Resources Sdn. Bhd.

The ENDGS pipeline was installed from the Beach Valve at Terengganu Gas Terminal (TGAST) up to Pipeline Tie-In Facilities completing in total of approximately 280.9km long.

HGIS was providing the comprehensive Pre-Lay Survey, Surface and Underwater Positioning Support during Pipelay, Shore Approach Pipeline Installation, and Post-Lay Survey. The Pre-Lay and Post Lay campaign was divided into 2 sections covering approx. 8km at Nearshore and appox. 272km Offshore operations.

Key highlight of the project was having DLB 264 to conduct pipe-lay concurrently while a separate vessel by HGIS performing the Pre-Lay Survey ahead of DLB 264 with on-board processing. This high profile project consist of deployment of assets and resources on land, nearshore and offshore section carrying out simultaneous operations.

OBJECTIVE#1To provide data to Pipelay Barge (DLB 264) via Onboard Processing during Pre-lay Survey.

OBJECTIVE#2High Accuracy DGNSS System (GPS and GLONASS) at decimeter differential accuracy which allow more accurate positioning and navigation of the pipelay barge with minimal break down.
