The solution

NAM suc­cess­ful­ly mod­ern­ized its vast engi­neer­ing archive using GTX, ensur­ing fast retrieval, effi­cient updates, and secure dig­i­tal stor­age. The shift to hybrid edit­ing and EDM inte­gra­tion enabled seam­less col­lab­o­ra­tion, improv­ing off­shore main­te­nance plan­ning, reg­u­la­to­ry com­pli­ance, and cost efficiency.

NAM: Mod­ern­iz­ing engi­neer­ing doc­u­men­ta­tion for off­shore operations

Ned­er­landse Aar­dolie Maatschap­pij (NAM) faced dif­fi­cul­ties dig­i­tiz­ing 1 mil­lion engi­neer­ing draw­ings. With GTXRaster CAD® PLUS, NAM pri­or­i­tized crit­i­cal scans, stream­lined raster edit­ing, and enabled remote doc­u­ment access, ensur­ing effi­cient off­shore main­te­nance, legal com­pli­ance, and reduced costs.

Ned­er­landse Aar­dolie Maatschap­pij (NAM), found­ed in 1947 by Esso and Shell, is the lead­ing pro­duc­er of nat­ur­al gas in the Nether­lands, sup­ply­ing 70% of the country’s total gas demand. With over 1 mil­lion engi­neer­ing draw­ings, span­ning 30 years across mul­ti­ple loca­tions, NAM faced a sig­nif­i­cant chal­lenge in mod­ern­iz­ing and dig­i­tiz­ing its archive while ensur­ing the integri­ty of its off­shore and onshore facilities.

Chal­lenge

NAM’s his­tor­i­cal doc­u­men­ta­tion con­sist­ed most­ly of poly­ester-based engi­neer­ing draw­ings, mak­ing retrieval man­u­al, slow, and costly.

  • Only 10% of draw­ings were dig­i­tal, com­pli­cat­ing mod­i­fi­ca­tion cycles for ​“as built” updates.
  • Legal and oper­a­tional require­ments made accu­rate record-keep­ing essen­tial for plant integri­ty and safety.
  • Off­shore plants posed addi­tion­al logis­ti­cal hur­dles: engi­neers had to phys­i­cal­ly retrieve draw­ings before each vis­it, impact­ing main­te­nance efficiency.

Solu­tion

NAM imple­ment­ed a com­pre­hen­sive EDM (Elec­tron­ic Doc­u­ment Man­age­ment) sys­tem, inte­grat­ing GTXRaster­CAD® PLUS with Auto­CAD® 2000 across 18 net­worked seats.

  • High-res­o­lu­tion scan­ning & pri­or­i­ti­za­tion: Crit­i­cal ​“as built” draw­ings received high-qual­i­ty scans to enable future dig­i­tal mod­i­fi­ca­tions, while sec­ondary doc­u­ments were dig­i­tized more simply.
  • Hybrid raster & vec­tor edit­ing: GTX pro­vid­ed an effi­cient alter­na­tive to full vec­tor­iza­tion, allow­ing engi­neers to mod­i­fy scanned draw­ings direct­ly in AutoCAD®.
  • Secure access via the NAM intranet: Engi­neers gained struc­tured priv­i­leges for query­ing, view­ing, print­ing, and updat­ing draw­ings — ensur­ing con­trolled revi­sions and reg­u­la­to­ry compliance.

Result

By tran­si­tion­ing to GTXRaster­CAD® PLUS, NAM sig­nif­i­cant­ly improved engi­neer­ing effi­cien­cy and doc­u­ment accessibility:

  • Engi­neers now access and update crit­i­cal draw­ings remote­ly, elim­i­nat­ing man­u­al retrieval delays.
  • Off­shore teams have up-to-date schemat­ics at all times, enhanc­ing main­te­nance and safe­ty operations.
  • NAM stream­lined draw­ing revi­sions, ensur­ing com­pli­ance with legal and oper­a­tional stan­dards while reduc­ing costs.
