SURVEY
Some activity construction in land (onshore are) needed earth mapping data is produced by survey and topography mapping, horizontal and vertical control point measurement. Include in surey activity was giving services at construction activity until project finished (as-built survey).
Coastal area (inshore area) usually have definition area along beach between several meter from boundary of water high to land, and to ocean until 20-50m depth. This area was needed specific of technical survey and the most difficult of survey activity because coastal character like breaking wave and many coral became dangerous for navigation.
From boundary of beach to ocean usually definition as ocean (offshore area). Survey activity for this area was needed good planning because it has ‘hostile’ character for human, while he must living for several day.

OCEAN ENGINEERING
Specialises in developing metocean design and statistics to support coastal and ocean industry activities. We undertake using advanced statistical techniques on the choice of design practice. Methodologies for the derivation of environmental statistics for ocean engineering are well-established within the company. The range of project experience in this area has led to an in-depth knowledge of the regional ocean process, and a thorough understanding of the metocean data requirements and analysis techniques required for coastal, port and offshore developments etc
