Nigerian Agip Exploration Limited Tender Opportunity Provision of Geophysical & Geomorphological Survey in NAE Offshore Acreages

Posted by Chinyere on Mon 17th Dec, 2012 -

1.) Introduction
Nigerian Agip Exploration Limited (NAE) intends to put in place a global tender for the Provision of Geophysical & Geomorphological Survey Services in NAE Offshore Acreages.

The proposed contract shall have duration of two (2) years plus one optional year effective from the date of award of the contract for the service.

The geophysical & geomorphological sites survey contract, shall be executed on call-out basis as and when needed.

2.) Scope of Work
The scope of the contract shall cover the following without limitation:
Geophysical and Geomorphological Survey Services
  • Field area to be surveyed will be in water depths varying from 60 m to 2,100m The survey shall cover any significant area that will be utilized during the structure

lifecycle: as a minimum, survey area shall be as indicated in the following table

CONTRACTOR will have the responsibility to survey a larger area if so requested:

Offshore Structure: Mobile drilling rig jack-up platform fixed platforms
Bathy/Morphological Survey: 2 x 2 km area
Magnetometer Survey: 500 x 500 m area

Offshore Structure: Semisub / drilling ship and FPSO
Bathy/Morphological Survey: 3 x 3 km area, or larger to encompass the maximum expected anchor spread
Magnetometer Survey: Usually not necessary
  • The purpose of the survey is to carry out a thorough investigation of the seabed features with sufficient penetration and resolution to gather data that are essential for the emplacement of structures dedicated to hydrocarbon exploration and exploitation.
The scope of work shall include gathering detailed data about the water depth (high degree of precision), morphology and consistency of the seabed, presence of obstacles (wrecks, war surplus, etc) or pre-existent structures (pipelines, cables, etc) on the sea bottom, stratigraphy and lithology of shallow formations (few tens of meters below seabed), mechanical characteristics of the seabed, presence of shallow gas pockets and possible occurrence of oceanic Poseidon beds and banks and their relative density on the proposed platform/rig
location or pipeline routes.
  • Provide reconnaissance evaluation of seabed morphology, including topographic features (local steep slopes, channels, hills/dunes), unevenness (scour zones sand ripples, sand waves/dunes, seabed vegetation), geohazards (faults, landslide, rock outcrops/ridges, pockmarks/gas seepage, mud volcanoes, boulders, shallow gas, liquefaction potential induced by earthquakes or waves, hydrate zones), man—made hazards (ship-wrecks, well heads, flow lines, power cables and communication cables, debris, unexploded ordnances, chemical dump sites);
Geophysical & Geomorphological surveys include (Survey may be done by AUV):
  • Real time DGPS positioning system and navigation equipment for surface positioning of the mother vessel;
  • DGPS and high precision acoustic positioning, inertial navigation and Doppler velocity speed log to provide the AUV position (in case the latter system is adopted);
  • water column acoustic velocity measurement system;
  • bathymetry with multi and single beam swath echo sounder;
  • sea bed imaging with high resolution dual-frequency side scan sonar;
  • high resolution chirp sub bottom profiler;
  • magnetometer survey;
  • conductivity, temperature, depth (CTP) sensor;
  • deep stratigraphy imaging by means of high resolution multichannel survey with acoustic
  • source and streamer;
  • seabed sampling with gravity sampler, vibrocorer, piston sampler;
  • classification and testing of soil samples etc.;

The survey shall be conducted in two stages:
  • First general stage, where the specified area is covered with low resolution and detail, including multi beam echosounder, side scan sonar, sub-bottom profile and a 2-D high resolution siesmic. This survey shall be carried out on a line spacing suitable to ensure a survey coverage and data quality adequate for engineering and construction activities. Primary
  • tracklines shall be spaced maximum 150 to 200m and line spacing suitable to ensure the 100% coverage of the Side Scan Sonar with a proper overlap between adjoining lines.
  • Second detailed stage, where the above measurements are repeated with largely greater detail and resolution, across a limited area pertaining to the project structures and devices, with in addition magnetometer. This detailed survey shall be conducted in the specified areas of 1 x 1km.
