Construction Support

Construction Support

Atteris has significant expertise in project management and construction support.

Atteris has the expertise to assist our clients with:

Development of tendering and contracting strategies
Preparation of ITT documentation, such as contracts, pricing schedules, scopes of work, specifications and drawings
Review of tender submissions
Package management, project management, contract administration and construction supervision
Project close-out reports

Construction Method Development and Review

Construction and execution experience is a valuable part of a design engineer’s development.

We develop and review construction methodologies, often running internal workshops to ensure the most constructible designs. Understanding construction methodologies in the early project phases will reduce risk of cost and schedule overrun during execution, maintaining project value.

Expert Installation Services

Atteris personnel have provided installation engineering support to installation contractors around the world. In addition, we have supported cost optimisation and installation method selection activities for operators.

Our services include:

Pipelay installation analysis and lay table preparation
Dynamic lifting analyses and calculations
Flexible and umbilical pull-in analysis
Development of installation procedures
Seafastening calculations
Dynamics analyses of lay products to determine optimum layback and maximise operation envelopes
Abandonment and recovery analyses to ensure acceptable stresses are maintained
Independent review and verification

Dynamic Analyses

Our clients leverage our detailed understanding of hydrodynamics, vessel motions and operational considerations to perform offshore installation analyses for any type of subsea structure or component.
