http://www.dreamstime.com/-image12074670NAUTIC is a specialist engineering contractor engaged in the inspection, repair, maintenance and installation of offshore and subsea structures as well as the design and construction of sustainable barges.

By combining the latest Ultra-High-Performance Cement (UHPC) technologies and subsea intervention systems with state-of-the-art grouting and installation equipment, NAUTIC offers bespoke solutions encompassing specialist consultancy, design, project management, field supervision and supply of offshore equipment and cementitious grouts. NAUTIC is a pioneer in the development, design, construction and commissioning of dry-docking free and corrosion resistant cargo and accommodation barges built in Ultra-Lightweight Cement Composite (ULCC) materials.

NAUTIC’s growth is continuously supported by research and development activities on Ultra Lightweight Cement Composite materials, High-Performance and Ultra-High-Performance Cementitious grouts. NAUTIC designs and manufactures proprietary cementitious grouts marketed under the NaX™ Premix System.

NAUTIC serves its client base locally with a growing network of regional and branch offices across Asia, the Middle-East and Central America.

Offshore Requalification



Reviving Ageing Offshore Assets

NAUTIC translates proven engineering concepts to offshore grouting applications helping Oil & Gas companies to maximise the utilisation of their offshore assets.

NAUTIC’s requalification services involve the strategic grouting of legs, joints and braces through the use of Ultra High Performance Cementitious (UHPC, NaX Q140™ and NaX™ B190) grouts or the installation of UHPC grouted structural clamps and sleeves. Subsea strengthening and repair measures are developed and designed by NAUTIC’s team of experienced engineers through global and local structural in-place analysis using SACS and ABAQUS.

Increasing the structural capacity of braces and joints by injecting UHPC grouts or deploying UHPC grouted clamps and sleeves is arguably the most cost effective and technically efficient option available. The injection of UHPC grouts, which in compression reach strengths that are similar to steel, is a swift operation with comparatively little offshore work involved. The application of UHPC grouts significantly increases the structural capacity of both tubular braces and fatigue exposed joints. NaX™ Q140 and NaX™ B190 UHPC grouts are designed and manufactured by NAUTIC and marketed under the NaX™ Premix System series.

NAUTIC’s offshore requalification services include:

  • Subsea inspection
  • Structural analysis and design
  • Subsea strengthening and repair works
  • Corrosion protection
  • Offshore asset certification
