Oceanographic and Met-Ocean Studies


Economic evaluation of an offshore lease can be aided by advance knowledge of ocean conditions. This advance knowledge is usually obtained from an oceanographic/meteorological study. Experience shows that a more usable study results if a detailed specification is followed. In this regard, GSIPL is a guide to preparing such a specification. A well-prepared specification enhances the usability of results, and simplifies the administration of the contract. It can also avoid much wasted effort on the part of the contractor and the project can proceed in the most expeditious manner.

The decision to proceed with acquisition, exploration, and development of an offshore lease requires favorable economics. Economic evaluation can be aided by advance knowledge of operating conditions (that is, wave, wind, current, and visibility conditions). This knowledge could make the difference between reliable or risky operations; profit or no profit; and government approval or rejection.

GSIPL offers such services for an advanced knowledge which is usually obtained from an oceanographic/meteorological study. The relatively small cost of the study is more than off set by safer and less costly operations. These operations result from information that is adequate to

  • Select design parameters that minimize the risk of failure and yet avoid over-design
  • Make weather down-time estimates (for over-all economic evaluation)
  • Select drilling vessels and equipment appropriate for operating conditions; and
  • Schedule construction to coincide with favorable weather.

GSIPL works with an intention to use oceanographic/meteorological information for planning and designing by demonstrating to government and to the public that the industry is doing its part to protect the ocean and shoreline environment. In considering an oceanographic/meteorological study, the operator faces the task of satisfying his data needs at a reasonable cost. has extensive stock of current meters, wave & metocean buoys.

GSIPL has Currentmeters – 2D ACM [2 Direction Acoustic Currentmeter], TeleDyne’s ADCP [Acoustic Doppler Current meter] and performs such studies with experienced specialists, offshore studies, extensive references, weather charts, etc., to develop the information required for an operation. Since wide variety of methods are used in developing oceanographic and meteorological information for offshore operations because of differences in marine conditions, the amount and types of data available, and the scope of study required by the
