1.1 Introduction

A soil investigation programme is necessary to provide information for design and construction and for the environmental assessment. The purpose of a soil investigation are :

1. To evaluate the general suitability of the site for the proposed project.
2. To enable an adequate and economical design to be made.
3. To disclose and make provision for difficulties that may arise during construction due to ground and other local conditions.

Prior to any works, soil investigation works are required to determine the profile and the engineering characteristics of the sub-seabed soil in the vicinity of the proposed site based on the British Standard Code of Practice BS5930 – Site Investigations and ASTM D 3441 as well.

Positioning of offshore boreholes was done by DGPS. The as-built location is targeted to be within a radius of 5m from the proposed location. Exploratory drilling was performed to obtain soil samples for visual inspection and laboratory testing. It was performed by using rotary boring machine mounted on the jack-up barge.

All necessary onshore works shall be carried out including the accurate setting out of borehole locations based on given...
