What we do


Offshore platform at dusk

Advisian provides a comprehensive world-class specialist engineering and project delivery service in offshore facilities, strengthened by our contractor and concept independent approach.

Fixed Structures

Integrity management of fixed offshore structures is a full lifecycle process that starts at the design level and continues through till decommissioning.  It encompasses a variety of disciplines combined with a thorough understanding of regulatory frameworks.  It also deals with customer expectations in terms of managing the risk of failures associated with an asset or a group of assets.

The offshore fixed structures demand stream offers the following services:

  • SIM and reliability assessments to API or ISO standards
  • Pushover analyses and determination of the reserve strength ratio
  • Risk assessment and inspection programs
  • Response of a structure to increased metocean conditions or due to brownfield modifications
  • Advanced analysis support for brownfield modifications
  • Rapid response, damage assessment services and anomaly resolution

Subsea and Offshore Pipelines (SURF)

Our global network of consultants provide integrity management solutions from conceptual investigations to aging deepwater facilities for Subsea and Offshore Pipelines (SURF). We assist our customers to prevent or resolve integrity issues should they occur through targeted investigations, troubleshooting, conceptual and functional design and advisory services.

As a part of the larger Advisian organization, INTECSEA brings a unique blend of technical project management, operational and regulatory expertise. The team offers services across:

  • Existing shallow and deepwater production facilities
  • New technologies and existing systems
  • Idle subsea equipment Integration of subsea systems for offshore oil and gas platforms
  • Flowline and riser systems and components

Floating Structures

Our offshore floating structure services are built on the core skills of INTECSEA, specializing in deepwater and FPSO/FSO integrity management solutions. Our consultants provide comprehensive solutions and integrity support for floating systems of all types:

  • TLPs
  • SPARs
  • Monohulls
  • Semi-submersibles

These customized solutions meet our customers’ standards as well as the requirements of various regulatory bodies, and are delivered via strong, well established core technical expertise in:

  • Naval architecture
  • Structural engineering
  • Mooring systems
  • Riser systems
  • Installation planning and management
  • Engineering management

Our knowledge of all aspects of floating systems and the various interfaces between the vessel hull, production process equipment, mooring and riser systems, and offloading systems, allow us to assess a facility from an overall systems level.

SAFEstart (Simulated Asset and Facilities Exercise)

Our best-in-class, real-time simulation and training delivery (SAFEstart) offers a customisable approach to operator training for new developments and complex fields, building operator confidence prior to live management of operations.

By enabling a step-by-step virtual guide to field operations in a controlled environment, operators have a higher probability of identifying and mitigating unforeseen issues. SAFEstart can be used to identify potentially costly and time consuming errors, offline, with minimal impact to critical path operations.

The SAFEstart interface links complex subsurface, pipeline, and facilities models to seamlessly create a realistic control room operational environment. Existing models can be utilized, including HYSYS and OLGA.
