Vessel Hull Modelling and Calculations of Inertia Properties

Project Scope

The overall project scope consisted of detail design of marine facilities associated with development of a new port. The tanker vessel utilized and mooring arrangements had to be purpose built. Our scope consisted of generating hull mesh of a representative vessel and deriving inertia properties for various loading conditions.

Field Mooring Buoy Integrity Assessment

Project Scope

The scope of work consisted modelling of a field mooring buoy as per the as built mooring arrangement and perform analysis to assess its suitability for the field mooring operations of referenced vessels. The study work generated the OSV’s RAOs and established the limiting weather conditions. Lack of as-built data of the facility and OSV were the main challenges faced in developing an accurate hydrodynamic model of the facilities.

Some of our previous major projects with key contribution by individual team members are described as below;

Gjoa development Project

Project Scope

The Gjoa field is located in the North Sea and involved a shallow water field development with semi-submersible, risers, umbilicals, rigid pipelines and subsea templates. It was Norway’s largest offshore development till that year and first project to have power from shore to reduce to emissions. The project involved complex interfaces, large deliveries, new suppliers and complex technical solutions.

Work performed

Management of riser delivery contract from tendering phase through installation
Design, fabrication, integration testing and installation of subsea assets
Management of risk and supervision register, change procedures and non-conformance reports
Conduct design reviews, manufacturing readiness review, and HSE inspections
Participate in HAZOP and carry out load out and offshore installation of flexible risers
Execution of Risk mitigation and safety studies

Visund Nord Development Project

Project scope

The development includes a semi-submersible integrated accommodation, drilling and processing platform with subsea wells. Visund Nord is an oil and gas field located north of existing Visund platform in the North Sea. Due to a gas leak at Visund Platform, an emergency shutdown procedure was enforced leading to hydrate formations in the pipeline and riser. During the hydrate removal operation, multiple burst holes were identified and the system was regarded not fit for purpose. The project scope was to replace the system and safely recover existing subsea infrastructure.

Work performed

Assessment of integrity of riser, pipeline and subsea structures prior to recovery operations
Preparation of underwater inspection plan and evaluation of survey reports
Management of concept and FEED study work
Development of riser recovery procedure
Modification of host platform to accommodate updated design conditions and revised riser loads

Various conceptual and feasibility field development studies in North West Shelf, Australia

Work performed

Execution of subsea field development activities including feasibility design, installation and cost estimation activities within the area of subsea systems, SURF and pipelines;
Material selection and corrosion control alternatives for risers and pipeline;
Lead the flow assurance and subsea field development activities;
Perform benchmarking of subsea life cycle costing and scheduling;
Development of conceptual subsea field production and distribution schematics ;
Develop riser integrity management, subsea functioning and by-pass philosophies;
Cost estimation and scheduling.

Chinguitti Field Development

Project scope

The Chinguetti field is located offshore Mauritania in the water depth of 800m in West Africa region. The Reference Case development for Chinguetti comprises a system of subsea manifolds, flowlines, risers connected to a permanently turret moored FPSO. An electro-hydraulic control umbilical and subsea chemical distribution system were used to control the subsea facilities and distribute chemicals for flow assurance purposes. The project comprised of a complex dynamic risers and umbilicals system design for a turret moored FPSO.

Work performed

Development of comprehensive analysis premise in compliance with contract specification and industry safe practice codes
Perform extreme event, interference and fatigue finite element analysis of the system using Flexcom and Orcaflex;
Develop cost effective technical solution ensuring safety is considered in the system design
