For many field developments, floating structures can play a vital link and can have a large impact on the feasibility and practicality of the project. Peritus has in-depth knowledge and extensive experience in supporting field development and screening appropriate floating structure selection through to executing sophisticated analysis.
Typically, the floating structures work undertaken by Peritus covers screening, hydrodynamic (motions), stability, structural and mooring analysis and Riser analysis (in conjunction with the Peritus’ dedicated Riser group) across all design engineering phases (including Operate) and can be described broadly by the following activities:
Our services are structured under four broad headings:
Our services are applicable to any company, region, and size of field or water depth. The scope of our services is different for every client and is based on discussion or preliminary studies to identify requirements. Peritus adds value to its customers in these projects through its combined commercial and technical expertise.
These activities could occur anywhere from the pre-exploration, to post discovery, or even at a brown-field redevelopment stage and include:
Peritus, as a leading provider of specialised services offers the right expertise to undertake and support appropriate independent risk assessment of floating structure designs. Through their integrated offices, this can be the introduction of new floating structure technologies into new regions (such as FPSO into the GoM or Semi and TLP into Asia Pacific) or and the detailed knowledge of how to address local environmental design criteria) through to the risk assessment of the New Technologies aspects such as FLNG. For FLNG, Peritus can provide independent expertise identifying the new technology aspects (such as offshore storage and loading) but can also provide a systematic approach to measure maturity and ensure appropriate alternatives are carried till the risk is adequately mitigated.
Peritus has the capability to screen and analyse floating structures and their associated mooring systems, either as part of early screening or specialized analysis during FEED and Execute. During the initial evaluation phases, Peritus can undertake preliminary sizing, strength analysis, hydrodynamics (motions) and stability to identify insights appropriate for the environment. Whether it is challenges associated with floating structures and their associated riser systems (such as Semi or TLP and steel catenary risers in harsh and swell environments) or floating structures in shallower water where mooring and riser systems can be equally challenging. Activities can include:
These activities are typically in support of Operator’s conversion, or re-conversion projects. Activities would include:
These activities are typically in support of Operator’s new, conversion, or re-conversion projects. Activities would include:
Pertius employs subject matter experts across the disciplines that can innovate and solve complex and challenging issues supporting unconventional lower cost project execution. Capabilities include:
For operators, the selection of the contract strategy and the tender preparation and management is actually the most critical activity towards a successful Floating Structure development. These activities are in support of Operators’ projects; Peritus can develop such strategies (including framing workshops) or support the Operator in assessing and selecting an appropriate contract strategy for the development.
Peritus Floating Structures Staff have experience developing the following contract strategies and as well as developing these for the Operator can provide valuable lessons learned:
As part of developing the contract strategy, or once already developed by the Operator, Peritus can develop the technical package including scope and specifications to support the Invitation to Bid. Activities include:
The primary External analysis tools used by PERITUS are:
In addition to discipline engineering roles, Peritus can and has provided Project Management Services in the form of provision of senior staff to owners engineering roles; supervising the design contractors during Develop and Execute.
These activities can either be in an execution mode, typically in support of contractors or Operator. Activities would include:
